Atomically Thin Materials Significantly Shrink Qubits



Quantum computing is a devilishly complex technology, with many technical hurdles impacting its development. Of these challenges two critical issues stand out: miniaturization and qubit quality.

IBM has adopted the superconducting qubit road map of reaching a 1,121-qubit processor by 2023, leading to the expectation that 1,000 qubits with today’s qubit form factor is feasible. However, current approaches will require very large chips (50 millimeters on a side, or larger) at the scale of small wafers, or the use of chiplets on multichip modules. While this approach will work, the aim is to attain a better path toward scalability.

Now researchers at MIT have been able to both reduce the size of the qubits and done so in a way that reduces the interference that occurs between neighboring qubits. The MIT researchers have increased the number of superconducting qubits that can be added onto a device by a factor of 100.

“We are addressing both qubit miniaturization and quality,” said William Oliver, the director for the Center for Quantum Engineering at MIT. “Unlike conventional transistor scaling, where only the number really matters, for qubits, large numbers are not sufficient, they must also be high-performance. Sacrificing performance for qubit number is not a useful trade in quantum computing. They must go hand in hand.”

The key to this big increase in qubit density and reduction of interference comes down to the use of two-dimensional materials, in particular the 2D insulator hexagonal boron nitride (hBN). The MIT researchers demonstrated that a few atomic monolayers of hBN can be stacked to form the insulator in the capacitors of a superconducting qubit.

Just like other capacitors, the capacitors in these superconducting circuits take the form of a sandwich in which an insulator material is sandwiched between two metal plates. The big difference for these capacitors is that the superconducting circuits can operate only at extremely low temperatures—less than 0.02 degrees above absolute zero (-273.15 °C).

Superconducting qubits are measured at temperatures as low as 20 millikelvin in a dilution refrigerator.Nathan Fiske/MIT

In that environment, insulating materials that are available for the job, such as PE-CVD silicon oxide or silicon nitride, have quite a few defects that are too lossy for quantum computing applications. To get around these material shortcomings, most superconducting circuits use what are called coplanar capacitors. In these capacitors, the plates are positioned laterally to one another, rather than on top of one another.

As a result, the intrinsic silicon substrate below the plates and to a smaller degree the vacuum above the plates serve as the capacitor dielectric. Intrinsic silicon is chemically pure and therefore has few defects, and the large size dilutes the electric field at the plate interfaces, all of which leads to a low-loss capacitor. The lateral size of each plate in this open-face design ends up being quite large (typically 100 by 100 micrometers) in order to achieve the required capacitance.

In an effort to move away from the large lateral configuration, the MIT researchers embarked on a search for an insulator that has very few defects and is compatible with superconducting capacitor plates.

“We chose to study hBN because it is the most widely used insulator in 2D material research due to its cleanliness and chemical inertness,” said colead author Joel Wang, a research scientist in the Engineering Quantum Systems group of the MIT Research Laboratory for Electronics.

On either side of the hBN, the MIT researchers used the 2D superconducting material, niobium diselenide. One of the trickiest aspects of fabricating the capacitors was working with the niobium diselenide, which oxidizes in seconds when exposed to air, according to Wang. This necessitates that the assembly of the capacitor occur in a glove box filled with argon gas.

While this would seemingly complicate the scaling up of the production of these capacitors, Wang doesn’t regard this as a limiting factor.

“What determines the quality factor of the capacitor are the two interfaces between the two materials,” said Wang. “Once the sandwich is made, the two interfaces are “sealed” and we don’t see any noticeable degradation over time when exposed to the atmosphere.”

This lack of degradation is because around 90 percent of the electric field is contained within the sandwich structure, so the oxidation of the outer surface of the niobium diselenide does not play a significant role anymore. This ultimately makes the capacitor footprint much smaller, and it accounts for the reduction in cross talk between the neighboring qubits.

“The main challenge for scaling up the fabrication will be the wafer-scale growth of hBN and 2D superconductors like [niobium diselenide], and how one can do wafer-scale stacking of these films,” added Wang.

Wang believes that this research has shown 2D hBN to be a good insulator candidate for superconducting qubits. He says that the groundwork the MIT team has done will serve as a road map for using other hybrid 2D materials to build superconducting circuits.

The Unlikely Inventor of the Automatic Rice Cooker



“Cover, bring to a boil, then reduce heat. Simmer for 20 minutes.” These directions seem simple enough, and yet I have messed up many, many pots of rice over the years. My sympathies to anyone who’s ever had to boil rice on a stovetop, cook it in a clay pot over a kerosene or charcoal burner, or prepare it in a cast-iron cauldron. All hail the 1955 invention of the automatic rice cooker!

How the automatic rice cooker was invented

It isn’t often that housewives get credit in the annals of invention, but in the story of the automatic rice cooker, a woman takes center stage. That happened only after the first attempts at electrifying rice cooking, starting in the 1920s, turned out to be utter failures. Matsushita, Mitsubishi, and Sony all experimented with variations of placing electric heating coils inside wooden tubs or aluminum pots, but none of these cookers automatically switched off when the rice was done. The human cook—almost always a wife or daughter—still had to pay attention to avoid burning the rice. These electric rice cookers didn’t save any real time or effort, and they sold poorly.

This article is part of our special report, “Reinventing Invention: Stories from Innovation’s Edge.”

But Shogo Yamada, the energetic development manager of the electric appliance division for Toshiba, became convinced that his company could do better. In post–World War II Japan, he was demonstrating and selling electric washing machines all over the country. When he took a break from his sales pitch and actually talked to women about their daily household labors, he discovered that cooking rice—not laundry—was their most challenging chore. Rice was a mainstay of the Japanese diet, and women had to prepare it up to three times a day. It took hours of work, starting with getting up by 5:00 am to fan the flames of a kamado, a traditional earthenware stove fueled by charcoal or wood on which the rice pot was heated. The inability to properly mind the flame could earn a woman the label of “failed housewife.”

In 1951, Yamada became the cheerleader of the rice cooker within Toshiba, which was understandably skittish given the past failures of other companies. To develop the product, he turned to Yoshitada Minami, the manager of a small family factory that produced electric water heaters for Toshiba. The water-heater business wasn’t great, and the factory was on the brink of bankruptcy.

How Sources Influence the Telling of History


As someone who does a lot of research online, I often come across websites that tell very interesting histories, but without any citations. It takes only a little bit of digging before I find entire passages copied and pasted from one site to another, and so I spend a tremendous amount of time trying to track down the original source. Accounts of popular consumer products, such as the rice cooker, are particularly prone to this problem. That’s not to say that popular accounts are necessarily wrong; plus they are often much more engaging than boring academic pieces. This is just me offering a note of caution because every story offers a different perspective depending on its sources.

For example, many popular blogs sing the praises of Fumiko Minami and her tireless contributions to the development of the rice maker. But in my research, I found no mention of Minami before Helen Macnaughtan’s 2012 book chapter, “Building up Steam as Consumers: Women, Rice Cookers and the Consumption of Everyday Household Goods in Japan,” which itself was based on episode 42 of the Project X: Challengers documentary series that was produced by NHK and aired in 2002.

If instead I had relied solely on the description of the rice cooker’s early development provided by the Toshiba Science Museum (here’s an archived page from 2007), this month’s column would have offered a detailed technical description of how uncooked rice has a crystalline structure, but as it cooks, it becomes a gelatinized starch. The museum’s website notes that few engineers had ever considered the nature of cooking rice before the rice-cooker project, and it refers simply to the “project team” that discovered the process. There’s no mention of Fumiko.

Both stories are factually correct, but they emphasize different details. Sometimes it’s worth asking who is part of the “project team” because the answer might surprise you. —A.M.


Although Minami understood the basic technical principles for an electric rice cooker, he didn’t know or appreciate the finer details of preparing perfect rice. And so Minami turned to his wife, Fumiko.

Fumiko, the mother of six children, spent five years researching and testing to document the ideal recipe. She continued to make rice three times a day, carefully measuring water-to-rice ratios, noting temperatures and timings, and prototyping rice-cooker designs. Conventional wisdom was that the heat source needed to be adjusted continuously to guarantee fluffy rice, but Fumiko found that heating the water and rice to a boil and then cooking for exactly 20 minutes produced consistently good results.

But how would an automatic rice cooker know when the 20 minutes was up? A suggestion came from Toshiba engineers. A working model based on a double boiler (a pot within a pot for indirect heating) used evaporation to mark time. While the rice cooked in the inset pot, a bimetallic switch measured the temperature in the external pot. Boiling water would hold at a constant 100 °C, but once it had evaporated, the temperature would soar. When the internal temperature of the double boiler surpassed 100 °C, the switch would bend and cut the circuit. One cup of boiling water in the external pot took 20 minutes to evaporate. The same basic principle is still used in modern cookers.



Yamada wanted to ensure that the rice cooker worked in all climates, so Fumiko tested various prototypes in extreme conditions: on her rooftop in cold winters and scorching summers and near steamy bathrooms to mimic high humidity. When Fumiko became ill from testing outside, her children pitched in to help. None of the aluminum and glass prototypes, it turned out, could maintain their internal temperature in cold weather. The final design drew inspiration from the Hokkaidō region, Japan’s northernmost prefecture. Yamada had seen insulated cooking pots there, so the Minami family tried covering the rice cooker with a triple-layered iron exterior. It worked.

How Toshiba sold its automatic rice cooker

Toshiba’s automatic rice cooker went on sale on 10 December 1955, but initially, sales were slow. It didn’t help that the rice cooker was priced at 3,200 yen, about a third of the average Japanese monthly salary. It took some salesmanship to convince women they needed the new appliance. This was Yamada’s time to shine. He demonstrated using the rice cooker to prepare takikomi gohan, a rice dish seasoned with dashi, soy sauce, and a selection of meats and vegetables. When the dish was cooked in a traditional kamado, the soy sauce often burned, making the rather simple dish difficult to master. Women who saw Yamada’s demo were impressed with the ease offered by the rice cooker.

Another clever sales technique was to get electricity companies to serve as Toshiba distributors. At the time, Japan was facing a national power surplus stemming from the widespread replacement of carbon-filament lightbulbs with more efficient tungsten ones. The energy savings were so remarkable that operations at half of the country’s power plants had to be curtailed. But with utilities distributing Toshiba rice cookers, increased demand for electricity was baked in.

Within a year, Toshiba was selling more than 200,000 rice cookers a month. Many of them came from the Minamis’ factory, which was rescued from near-bankruptcy in the process.

How the automatic rice cooker conquered the world

From there, the story becomes an international one with complex localization issues. Japanese sushi rice is not the same as Thai sticky rice which is not the same as Persian tahdig, Indian basmati, Italian risotto, or Spanish paella. You see where I’m going with this. Every culture that has a unique rice dish almost always uses its own regional rice with its own preparation preferences. And so countries wanted their own type of automatic electric rice cooker (although some rejected automation in favor of traditional cooking methods).

Yoshiko Nakano, a professor at the University of Hong Kong, wrote a book in 2009 about the localized/globalized nature of rice cookers. Where There Are Asians, There Are Rice Cookers traces the popularization of the rice cooker from Japan to China and then the world by way of Hong Kong. One of the key differences between the Japanese and Chinese rice cooker is that the latter has a glass lid, which Chinese cooks demanded so they could see when to add sausage. More innovation and diversification followed. Modern rice cookers have settings to give Iranians crispy rice at the bottom of the pot, one to let Thai customers cook noodles, one for perfect rice porridge, and one for steel-cut oats.



My friend Hyungsub Choi, in his 2022 article “Before Localization: The Story of the Electric Rice Cooker in South Korea,” pushes back a bit on Nakano’s argument that countries were insistent on tailoring cookers to their tastes. From 1965, when the first domestic rice cooker appeared in South Korea, to the early 1990s, Korean manufacturers engaged in “conscious copying,” Choi argues. That is, they didn’t bother with either innovation or adaptation. As a result, most Koreans had to put up with inferior domestic models. Even after the Korean government made it a national goal to build a better rice cooker, manufacturers failed to deliver one, perhaps because none of the engineers involved knew how to cook rice. It’s a good reminder that the history of technology is not always the story of innovation and progress.

Eventually, the Asian diaspora brought the rice cooker to all parts of the globe, including South Carolina, where I now live and which coincidentally has a long history of rice cultivation. I bought my first rice cooker on a whim, but not for its rice-cooking ability. I was intrigued by the yogurt-making function. Similar to rice, yogurt requires a constant temperature over a specific length of time. Although successful, my yogurt experiment was fleeting—store-bought was just too convenient. But the rice cooking blew my mind. Perfect rice. Every. Single. Time. I am never going back to overflowing pots of starchy water.

Principles of PID Controllers



Thanks to their ability to adjust the system’s output accurately and quickly without detailed knowledge about its dynamics, PID control loops stand as a powerful and widely used tool for maintaining a stable and predictable output in a variety of applications. In this paper, we review the fundamental principles and characteristics of these control systems, providing insight into their functioning, tuning strategies, advantages, and trade-offs.

As a result of their integrated architecture, Zurich Instruments’ lock-in amplifiers allow users to make the most of all the advantages of digital PID control loops, so that their operation can be adapted to match the needs of different use cases.

Teens Gain Experience at IEEE’s TryEngineering Summer Institute



The future of engineering is bright, and it’s being shaped by the young minds at the TryEngineering Summer Institute (TESI), a program administered by IEEE Educational Activities. This year more than 300 students attended TESI to fuel their passion for engineering and prepare for higher education and careers. Sessions were held from 30 June through 2 August on the campuses of Rice University, the University of Pennsylvania, and the University of San Diego.

The program is an immersive experience designed for students ages 13 to 17. It offers hands-on projects, interactive workshops, field trips, and insights into the profession from practicing engineers. Participants get to stay on a college campus, providing them with a preview of university life.

Student turned instructor

One future innovator is Natalie Ghannad, who participated in the program as a student in 2022 and was a member of this year’s instructional team in Houston at Rice University. Ghannad is in her second year as an electrical engineering student at the University of San Francisco. University students join forces with science and engineering teachers at each TESI location to serve as instructors.

For many years, Ghannad wanted to follow in her mother’s footsteps and become a pediatric neurosurgeon. As a high school junior in Houston in 2022, however, she had a change of heart and decided to pursue engineering after participating in the TESI at Rice. She received a full scholarship from the IEEE Foundation TESI Scholarship Fund, supported by IEEE societies and councils.

“I really liked that it was hands-on,” Ghannad says. “From the get-go, we were introduced to 3D printers and laser cutters.”

The benefit of participating in the program, she says, was “having the opportunity to not just do the academic side of STEM but also to really get to play around, get your hands dirty, and figure out what you’re doing.”

“Looking back,” she adds, “there are so many parallels between what I’ve actually had to do as a college student, and having that knowledge from the Summer Institute has really been great.”

She was inspired to volunteer as a teaching assistant because, she says, “I know I definitely want to teach, have the opportunity to interact with kids, and also be part of the future of STEM.”

More than 90 students attended the program at Rice. They visited Space Center Houston, where former astronauts talked to them about the history of space exploration.

Participants also were treated to presentations by guest speakers including IEEE Senior Member Phil Bautista, the founder of Bull Creek Data, a consulting company that provides technical solutions; IEEE Senior Member Christopher Sanderson, chair of the IEEE Region 5 Houston Section; and James Burroughs, a standards manager for Siemens in Atlanta. Burroughs, who spoke at all three TESI events this year, provided insight on overcoming barriers to do the important work of an engineer.

Learning about transit systems and careers

The University of Pennsylvania, in Philadelphia, hosted the East Coast TESI event this year. Students were treated to a field trip to the Southeastern Pennsylvania Transportation Association (SEPTA), one of the largest transit systems in the country. Engineers from AECOM, a global infrastructure consulting firm with offices in Philadelphia that worked closely with SEPTA on its most recent station renovation, collaborated with IEEE to host the trip.

The benefit of participating in the program was “having the opportunity to not just do the academic side of STEM but also to really get to play around, get your hands dirty, and figure out what you’re doing.” — Natalie Ghannad

Participants also heard from guest speakers including Api Appulingam, chief development officer of the Philadelphia International Airport, who told the students the inspiring story of her career.

Guest speakers from Google and Meta

Students who attended the TESI camp at the University of San Diego visited Qualcomm. Hosted by the IEEE Region 6 director, Senior Member Kathy Herring Hayashi, they learned about cutting-edge technology and toured the Qualcomm Museum.

Students also heard from guest speakers including IEEE Member Andrew Saad, an engineer at Google; Gautam Deryanni, a silicon validation engineer at Meta; Kathleen Kramer, 2025 IEEE president and a professor of electrical engineering at the University of San Diego; as well as Burroughs.

“I enjoyed the opportunity to meet new, like-minded people and enjoy fun activities in the city, as well as get a sense of the dorm and college life,” one participant said.

Hands-on projects

In addition to field trips and guest speakers, participants at each location worked on several hands-on projects highlighting the engineering design process. In the toxic popcorn challenge, the students designed a process to safely remove harmful kernels. Students tackling the bridge challenge designed and built a span out of balsa wood and glue, then tested its strength by gradually adding weight until it failed. The glider challenge gave participants the tools and knowledge to build and test their aircraft designs.

One participant applauded the hands-on activities, saying, “All of them gave me a lot of experience and helped me have a better idea of what engineering field I want to go in. I love that we got to participate in challenges and not just listen to lectures—which can be boring.”

The students also worked on a weeklong sparking solutions challenge. Small teams identified a societal problem, such as a lack of clean water or limited mobility for senior citizens, then designed a solution to address it. On the last day of camp, they pitched their prototypes to a team of IEEE members that judged the projects based on their originality and feasibility. Each student on the winning teams at each location were awarded the programmable Mech-5 robot.

Twenty-nine scholarships were awarded with funding from the IEEE Foundation. IEEE societies that donated to the cause were the IEEE Computational Intelligence Society, the IEEE Computer Society, the IEEE Electronics Packaging Society, the IEEE Industry Applications Society, the IEEE Oceanic Engineering Society, the IEEE Power & Energy Society, the IEEE Power Electronics Society, the IEEE Signal Processing Society, and the IEEE Solid-State Circuits Society.

New Carrier Fluid Makes Hydrogen Way Easier to Transport



Imagine pulling up to a refueling station and filling your vehicle’s tank with liquid hydrogen, as safe and convenient to handle as gasoline or diesel, without the need for high-pressure tanks or cryogenic storage. This vision of a sustainable future could become a reality if a Calgary, Canada–based company, Ayrton Energy, can scale up its innovative method of hydrogen storage and distribution. Ayrton’s technology could make hydrogen a viable, one-to-one replacement for fossil fuels in existing infrastructure like pipelines, fuel tankers, rail cars, and trucks.

The company’s approach is to use liquid organic hydrogen carriers (LOHCs) to make it easier to transport and store hydrogen. The method chemically bonds hydrogen to carrier molecules, which absorb hydrogen molecules and make them more stable—kind of like hydrogenating cooking oil to produce margarine.

A researcher pours a sample of Ayrton’s LOHC fluid into a vial.Ayrton Energy

The approach would allow liquid hydrogen to be transported and stored in ambient conditions, rather than in the high-pressure, cryogenic tanks (to hold it at temperatures below -252 ºC) currently required for keeping hydrogen in liquid form. It would also be a big improvement on gaseous hydrogen, which is highly volatile and difficult to keep contained.

Founded in 2021, Ayrton is one of several companies across the globe developing LOHCs, including Japan’s Chiyoda and Mitsubishi, Germany’s Covalion, and China’s Hynertech. But toxicity, energy density, and input energy issues have limited LOHCs as contenders for making liquid hydrogen feasible. Ayrton says its formulation eliminates these trade-offs.

Safe, Efficient Hydrogen Fuel for Vehicles

Conventional LOHC technologies used by most of the aforementioned companies rely on substances such as toluene, which forms methylcyclohexane when hydrogenated. These carriers pose safety risks due to their flammability and volatility. Hydrogenious LOHC Technologies in Erlanger, Germany and other hydrogen fuel companies have shifted toward dibenzyltoluene, a more stable carrier that holds more hydrogen per unit volume than methylcyclohexane, though it requires higher temperatures (and thus more energy) to bind and release the hydrogen. Dibenzyltoluene hydrogenation occurs at between 3 and 10 megapascals (30 and 100 bar) and 200–300 ºC, compared with 10 MPa (100 bar), and just under 200 ºC for methylcyclohexane.

Ayrton’s proprietary oil-based hydrogen carrier not only captures and releases hydrogen with less input energy than is required for other LOHCs, but also stores more hydrogen than methylcyclohexane can—55 kilograms per cubic meter compared with methylcyclohexane’s 50 kg/m³. Dibenzyltoluene holds more hydrogen per unit volume (up to 65 kg/m³), but Ayrton’s approach to infusing the carrier with hydrogen atoms promises to cost less. Hydrogenation or dehydrogenation with Ayrton’s carrier fluid occurs at 0.1 megapascal (1 bar) and about 100 ºC, says founder and CEO Natasha Kostenuk. And as with the other LOHCs, after hydrogenation it can be transported and stored at ambient temperatures and pressures.

Judges described [Ayrton's approach] as a critical technology for the deployment of hydrogen at large scale.” —Katie Richardson, National Renewable Energy Lab

Ayrton’s LOHC fluid is as safe to handle as margarine, but it’s still a chemical, says Kostenuk. “I wouldn’t drink it. If you did, you wouldn’t feel very good. But it’s not lethal,” she says.

Kostenuk and fellow Ayrton cofounder Brandy Kinkead (who serves as the company’s chief technical officer) were originally trying to bring hydrogen generators to market to fill gaps in the electrical grid. “We were looking for fuel cells and hydrogen storage. Fuel cells were easy to find, but we couldn’t find a hydrogen storage method or medium that would be safe and easy to transport to fuel our vision of what we were trying to do with hydrogen generators,” Kostenuk says. During the search, they came across LOHC technology but weren’t satisfied with the trade-offs demanded by existing liquid hydrogen carriers. “We had the idea that we could do it better,” she says. The duo pivoted, adjusting their focus from hydrogen generators to hydrogen storage solutions.

“Everybody gets excited about hydrogen production and hydrogen end use, but they forget that you have to store and manage the hydrogen,” Kostenuk says. Incompatibility with current storage and distribution has been a barrier to adoption, she says. “We’re really excited about being able to reuse existing infrastructure that’s in place all over the world.” Ayrton’s hydrogenated liquid has fuel-cell-grade (99.999 percent) hydrogen purity, so there’s no advantage in using pure liquid hydrogen with its need for subzero temperatures, according to the company.

The main challenge the company faces is the set of issues that come along with any technology scaling up from pilot-stage production to commercial manufacturing, says Kostenuk. “A crucial part of that is aligning ourselves with the right manufacturing partners along the way,” she notes.

Asked about how Ayrton is dealing with some other challenges common to LOHCs, Kostenuk says Ayrton has managed to sidestep them. “We stayed away from materials that are expensive and hard to procure, which will help us avoid any supply chain issues,” she says. By performing the reactions at such low temperatures, Ayrton can get its carrier fluid to withstand 1,000 hydrogenation-dehydrogenation cycles before it no longer holds enough hydrogen to be useful. Conventional LOHCs are limited to a couple of hundred cycles before the high temperatures required for bonding and releasing the hydrogen breaks down the fluid and diminishes its storage capacity, Kostenuk says.

Breakthrough in Hydrogen Storage Technology

In acknowledgement of what Ayrton’s nontoxic, oil-based carrier fluid could mean for the energy and transportation sectors, the U.S. National Renewable Energy Lab (NREL) at its annual Industry Growth Forum in May named Ayrton an “outstanding early-stage venture.” A selection committee of more than 180 climate tech and cleantech investors and industry experts chose Ayrton from a pool of more than 200 initial applicants, says Katie Richardson, group manager of NREL’s Innovation and Entrepreneurship Center, which organized the forum. The committee based its decision on the company’s innovation, market positioning, business model, team, next steps for funding, technology, capital use, and quality of pitch presentation. “Judges described Ayrton’s approach as a critical technology for the deployment of hydrogen at large scale,” Richardson says.

As a next step toward enabling hydrogen to push gasoline and diesel aside, “we’re talking with hydrogen producers who are right now offering their customers cryogenic and compressed hydrogen,” says Kostenuk. “If they offered LOHC, it would enable them to deliver across longer distances, in larger volumes, in a multimodal way.” The company is also talking to some industrial site owners who could use the hydrogenated LOHC for buffer storage to hold onto some of the energy they’re getting from clean, intermittent sources like solar and wind. Another natural fit, she says, is energy service providers that are looking for a reliable method of seasonal storage beyond what batteries can offer. The goal is to eventually scale up enough to become the go-to alternative (or perhaps the standard) fuel for cars, trucks, trains, and ships.

Honor a Loved One With an IEEE Foundation Memorial Fund



As the philanthropic partner of IEEE, the IEEE Foundation expands the organization’s charitable body of work by inspiring philanthropic engagement that ignites a donor’s innermost interests and values.

One way the Foundation does so is by partnering with IEEE units to create memorial funds, which pay tribute to members, family, friends, teachers, professors, students, and others. This type of giving honors someone special while also supporting future generations of engineers and celebrating innovation.

Below are three recently created memorial funds that not only have made an impact on their beneficiaries and perpetuated the legacy of the namesake but also have a deep meaning for those who launched them.

EPICS in IEEE Fischer Mertel Community of Projects

The EPICS in IEEE Fischer Mertel Community of Projects was established to support projects “designed to inspire multidisciplinary teams of engineering students to collaborate and engineer solutions to address local community needs.”

The fund was created by the children of Joe Fischer and Herb Mertel to honor their fathers’ passion for mentoring students. Longtime IEEE members, Fischer and Mertel were active with the IEEE Electromagnetic Compatibility Society. Fischer was the society’s 1972 president and served on its board of directors for six years. Mertel served on the society’s board from 1979 to 1983 and again from 1989 to 1993.

“The EPICS in IEEE Fischer Mertel Community of Projects was established to inspire and support outstanding engineering ideas and efforts that help communities worldwide,” says Tina Mertel, Herb’s daughter. “Joe Fischer and my father had a lifelong friendship and excelled as engineering leaders and founders of their respective companies [Fischer Custom Communications and EMACO]. I think that my father would have been proud to know that their friendship and work are being honored in this way.”

The nine projects supported thus far have the potential to impact more than 104,000 people because of the work and collaboration of 190 students worldwide. The projects funded are intended to represent at least two of the EPICS in IEEE’s focus categories: education and outreach; human services; environmental; and access and abilities.

Here are a few of the projects:

IEEE AESS Michael C. Wicks Radar Student Travel Grant

The IEEE Michael C. Wicks Radar Student Travel Grant was established by IEEE Fellow Michael Wicks prior to his death in 2022. The grant provides travel support for graduate students who are the primary authors on a paper being presented at the annual IEEE Radar Conference. Wicks was an electronics engineer and a radio industry leader who was known for developing knowledge-based space-time adaptive processing. He believed in investing in the next generation and he wanted to provide an opportunity for that to happen.Ten graduate students have been awarded the Wicks grant to date. This year two students from Region 8 (Africa, Europe, Middle East) and two students from Region 10 (Asia and Pacific) were able to travel to Denver to attend the IEEE Radar Conference and present their research. The papers they presented are “Target Shape Reconstruction From Multi-Perspective Shadows in Drone-Borne SAR Systems” and “Design of Convolutional Neural Networks for Classification of Ships from ISAR Images.”

IEEE Nick Holonyak Jr. Medal for Semiconductor Optoelectronic Technologies

The IEEE Nick Holonyak Jr. Medal for Semiconductor Optoelectronic Technologies was created with a memorial fund supported by some of Holonyak’s former graduate students to honor his work as a professor and mentor. Presented on behalf of the IEEE Board of Directors, the medal recognizes outstanding contributions to semiconductor optoelectronic devices and systems including high-energy-efficiency semiconductor devices and electronics.

Holonyak was a prolific inventor and longtime professor of electrical engineering and physics. In 1962, while working as a scientist at General Electric’s Advanced Semiconductor Laboratory in Syracuse, N.Y., he invented the first practical visible-spectrum LED and laser diode. His innovations are the basis of the devices now used in high-efficiency light bulbs and laser diodes. He left GE in 1963 to join the University of Illinois Urbana-Champaign as a professor of electrical engineering and physics at the invitation of John Bardeen, his Ph.D. advisor and a two-time Nobel Prize winner in physics. Holonyak retired from UIUC in 2013 but continued research collaborations at the university with young faculty members.

“In addition to his remarkable technical contributions, he was an excellent teacher and mentor to graduate students and young electrical engineers,” says Russell Dupuis, one of his doctoral students. “The impact of his innovations has improved the lives of most people on the earth, and this impact will only increase with time. It was my great honor to be one of his students and to help create this important IEEE medal to ensure that his work will be remembered in the future.”

The award was presented for the first time at this year’s IEEE Honors Ceremony, in Boston, to IEEE Fellow Constance Chang-Hasnain and Life Fellow Fumio Koyama for “pioneering contributions to vertical cavity surface-emitting laser (VCSEL) and VCSEL-based photonics for optical communications and sensing.”

Establishing a memorial fund through the IEEE Foundation is a gratifying way to recognize someone who has touched your life while also advancing technology for humanity.

Adaptive-morphology multirotors exhibit superior versatility and task-specific performance compared to traditional multirotors owing to their functional morphological adaptability. However, a notable challenge lies in the contrasting requirements of locking each morphology for flight controllability and efficiency while permitting low-energy reconfiguration. A novel design approach is proposed for reconfigurable multirotors utilizing soft multistable composite laminate airframes.

Foundation models from machine learning have enabled rapid advances in perception, planning, and natural language understanding for robots. However, current systems lack any rigorous assurances when required to generalize to novel scenarios. For example, perception systems can fail to identify or localize unfamiliar objects, and large language model (LLM)-based planners can hallucinate outputs that lead to unsafe outcomes when executed by robots. How can we rigorously quantify the uncertainty of machine learning components such that robots know when they don’t know and can act accordingly?

Katherine Bennell-Pegg: Australia’s First Astronaut Makes History



This is a sponsored article brought to you by BESydney.

In July 2024, Sydney woman Katherine Bennell-Pegg made history as the first astronaut to graduate under the Australian flag and the first female astronaut in Australia. Her journey, marked by determination and discipline, showcases Australia’s growing prominence in space exploration and research.

From her academic achievements at the University of Sydney (USYD) to her rigorous training at the European Space Agency (ESA), Bennell-Pegg’s success has paved a path forward for aspiring space and aerospace professionals in Australia and globally.

A journey to the stars begins in Sydney

Katherine Bennell-Pegg was born in Sydney, New South Wales, and grew up in the Northern Beaches area. Her fascination with space began at an early age.

“I always dreamed of being an astronaut,” Bennell-Pegg shared in her “Insights from an Australian Astronaut” Space Forum Speech in July 2024. “When I was young, it was for the adventure, but after more than a decade working in space, it’s now because I know the role it plays in tackling real-world problems and developing new knowledge that can benefit our society, environment and science.”

Sydney: A Hub for Space Innovation


Sydney, the vibrant heart of the state of New South Wales (NSW), stands at the forefront of aerospace innovation in Australia. With its world-class research facilities, leading academic institutions and strategic geographic positioning, Sydney is not only Australia’s gateway to the Indo-Pacific but also a burgeoning hub for international aerospace endeavours.

NSW is home to more than 40 per cent of Australia’s aerospace industry. Substantial investments from both the state and federal governments support this concentration of capabilities, underpinning Sydney’s role as a leader in aerospace. From advanced manufacturing and cybersecurity to quantum technologies and space exploration, this progressive city is truly thriving.

Sydney’s appeal as a desirable location for hosting aerospace conferences and business events is bolstered by its comprehensive infrastructure, vibrant startup community and strategic position as a transport hub.

Sydney’s track record of successfully hosting events highlights the city’s ability to organise impactful international gatherings, including:

  • Australian Space Summit

Sydney proved to be the ideal location for Bennell-Pegg’s journey to begin. She studied at the University of Sydney, where she earned a Bachelor of Engineering (Honors) in Aeronautical Engineering (Space) and a Bachelor of Science (Advanced) in Physics.

Sydney’s universities are at the forefront of aerospace education and research. Institutions such as the University of Sydney (USYD), the University of New South Wales (UNSW Sydney) and the University of Technology Sydney (UTS) attract students from around the world. UNSW Sydney, with its School of Aerospace, Mechanical, and Mechatronic Engineering, is renowned for its innovative research in space technology and satellite systems, while UTS provides cutting-edge programs in aerospace engineering and physics, emphasizing practical applications and industry partnerships. USYD excels in aeronautical engineering and space science, supported by advanced facilities and strong ties to major aerospace organisations. Together, these universities offer comprehensive programs that integrate theoretical knowledge with hands-on experience, preparing students for dynamic careers in the rapidly evolving aerospace and space sectors.

Having excelled in her studies at USYD, Bennell-Pegg was awarded the Charles Kuller Graduation Prize for her top-placed undergraduate thesis. Subsequently, her quest for knowledge took her to Europe, where she earned two Master of Science degrees: one in Astronautics and Space Engineering from Cranfield University and another in Space Technology from Luleå University of Technology.

Reflecting on her educational path, Bennell-Pegg stated, “With the encouragement of my parents, I researched what it would take to become an astronaut and worked hard at school, participating in everything from aerobatic flying lessons to amateur astronomy.”

Inside the rigorous training regimen of an astronaut

Bennell-Pegg’s professional career began with roles at Airbus UK, where she contributed to numerous space missions and concept studies, such as Martian in-situ resource utilisation and space debris removal. Her expertise led her to the Australian Space Agency, where she became the Director of Space Technology.

In 2021, Bennell-Pegg was invited by the European Space Agency (ESA) to undertake Basic Astronaut Training at the European Astronaut Centre in Germany. When the ESA application opened in 2021, it was the first opening in 15 years. Bennell-Pegg jumped at the opportunity to apply alongside over 22,000 others from 22 countries. She endured six knock-out rounds, including medical, psychometrics, psychology and technical tests and made it to the group of 25 who passed.

This historic invitation marked the first time an international astronaut candidate was offered training by the ESA.

“The training was demanding, but it was also an incredible opportunity to learn from some of the best minds in the field and to be part of a team that is pushing the boundaries of human exploration.”—Katherine Bennell-Pegg

Bennell-Pegg’s training regimen was intense, encompassing physical conditioning, complex simulations, and theoretical classes designed to prepare candidates for long-duration missions to the International Space Station (ISS) and beyond. This included:

  • Studies in biology, astronomy, earth sciences, meteorology, materials, medical and fluids, both in theory and in labs.
  • Radiation research – an area of expertise for Australia. This will increase as humans travel back to the Moon.
  • Medical operations: Astronauts need to be able to perform medical procedures on themselves and others.
  • Training for expeditions: This included honing team dynamics through behavioral training, ocean and winter survival training, rescue and firefighting.

Sharing her thoughts on this transformative experience, Bennell-Pegg said, “The training was demanding, but it was also an incredible opportunity to learn from some of the best minds in the field and to be part of a team that is pushing the boundaries of human exploration.”

In April 2024, Bennell-Pegg completed her training, graduating with her ESA classmates from “The Hoppers” group. Upon graduation, she became fully qualified for assignments on long-duration missions to the ISS, making her the first Australian female astronaut and the first person to train as an astronaut under the Australian flag.

“I want to use this experience to open doors for Australian scientists and engineers to utilize space for their discoveries,” Bennell-Pegg said. “I hope to inspire the pursuit of STEM careers and show all Australians that they too can reach for the stars.”

Elevating Australia’s role in space exploration

Katherine Bennell-Pegg’s achievements represent a significant milestone. Her journey from the University of Sydney to the rigorous training programs at the European Astronaut Centre showcases the potential of Australian talent in the global space community.

“Being the first astronaut trained under the Australian flag is an incredible honor,” Bennell-Pegg said. “I’m grateful for the support that has fueled me through intense training and opened doors for more Australians in space exploration. Whether I fly or not, there is much to accomplish here on Earth. I’m excited to leverage this experience to inspire future generations in STEM and elevate Australia’s presence in the global space community. Becoming an astronaut is just the beginning.”

Bennell-Pegg’s dream to become an Australian astronaut is more than just a personal triumph; it is a win for anyone who aspires to a career in space or aerospace. Sydney, with its world-class educational institutions, advanced manufacturing facilities scheduled for the Western Sydney Aerotropolis and expanding opportunities in aerospace and defence, is an ideal starting point for anyone looking to make their mark in these sectors.

Azerbaijan Plans Caspian-Black Sea Energy Corridor



Azerbaijan next week will garner much of the attention of the climate tech world, and not just because it will host COP29, the United Nation’s giant annual climate change conference. The country is promoting a grand, multi-nation plan to generate renewable electricity in the Caucasus region and send it thousands of kilometers west, under the Black Sea, and into energy–hungry Europe.

The transcontinental connection would start with wind, solar, and hydropower generated in Azerbaijan and Georgia, and off-shore wind power generated in the Caspian Sea. Long-distance lines would carry up to 1.5 gigawatts of clean electricity to Anaklia, Georgia, at the east end of the Black Sea. An undersea cable would move the electricity across the Black Sea and deliver it to Constanta, Romania, where it could be distributed further into Europe.

The scheme’s proponents say this Caspian-Black Sea energy corridor will help decrease global carbon emissions, provide dependable power to Europe, modernize developing economies at Europe’s periphery, and stabilize a region shaken by war. Organizers hope to build the undersea cable within the next six years at an estimated cost of €3.5 billion (US $3.8 billion).

To accomplish this, the governments of the involved countries must quickly circumvent a series of technical, financial, and political obstacles. “It’s a huge project,” says Zviad Gachechiladze, a director at Georgian State Electrosystem, the agency that operates the country’s electrical grid, and one of the architects of the Caucasus green-energy corridor. “To put it in operation [by 2030]—that’s quite ambitious, even optimistic,” he says.

Black Sea Cable to Link Caucasus and Europe

The technical lynchpin of the plan falls on the successful construction of a high voltage direct current (HVDC) submarine cable in the Black Sea. It’s a formidable task, considering that it would stretch across nearly 1,200 kilometers of water, most of which is over 2 km deep, and, since Russia’s invasion of Ukraine, littered with floating mines. By contrast, the longest existing submarine power cable—the North Sea Link—carries 1.4 GW across 720 km between England and Norway, at depths of up to 700 meters.

As ambitious as Azerbaijan’s plans sound, longer undersea connections have been proposed. The Australia-Asia PowerLink project aims to produce 6 GW at a vast solar farm in Northern Australia and send about a third of it to Singapore via a 4,300-km undersea cable. The Morocco-U.K. Power Project would send 3.6 GW over 3,800 km from Morocco to England. A similar attempt by Desertec to send electricity from North Africa to Europe ultimately failed.

Building such cables involves laying and stitching together lengths of heavy submarine power cables from specialized ships—the expertise for which lies with just two companies in the world. In an assessment of the Black Sea project’s feasibility, the Milan-based consulting and engineering firm CESI determined that the undersea cable could indeed be built, and estimated that it could carry up to 1.5 GW—enough to supply over 2 million European households.

But to fill that pipe, countries in the Caucasus region would have to generate much more green electricity. For Georgia, that will mostly come from hydropower, which already generates over 80 percent of the nation’s electricity. “We are a hydro country. We have a lot of untapped hydro potential,” says Gachechiladze.

Azerbaijan and Georgia Plan Green Energy Corridor

Generating hydropower can also generate opposition, because of the way dams alter rivers and landscapes. “There were some cases when investors were not able to construct power plants because of opposition of locals or green parties” in Georgia, says Salome Janelidze, a board member at the Energy Training Center, a Georgian government agency that promotes and educates around the country’s energy sector.

“It was definitely a problem and it has not been totally solved,” says Janelidze. But “to me it seems it is doable,” she says. “You can procure and construct if you work closely with the local population and see them as allies rather than adversaries.”

For Azerbaijan, most of the electricity would be generated by wind and solar farms funded by foreign investment. Masdar, the renewable-energy developer of the United Arab Emirates government, has been investing heavily in wind power in the country. In June, the company broke ground on a trio of wind and solar projects with 1 GW capacity. It intends to develop up to 9 GW more in Azerbaijan by 2030. ACWA Power, a Saudi power-generation company, plans to complete a 240-MW solar plant in the Absheron and Khizi districts of Azerbaijan next year and has struck a deal with the Azerbaijani Ministry of Energy to install up to 2.5 GW of offshore and onshore wind.

CESI is currently running a second study to gauge the practicality of the full breadth of the proposed energy corridor—from the Caspian Sea to Europe—with a transmission capacity of 4 to 6 GW. But that beefier interconnection will likely remain out of reach in the near term. “By 2030, we can’t claim our region will provide 4 GW or 6 GW,” says Gachechiladze. “1.3 is realistic.”

COP29: Azerbaijan’s Renewable Energy Push

Signs of political support have surfaced. In September, Azerbaijan, Georgia, Romania, and Hungary created a joint venture, based in Romania, to shepherd the project. Those four countries in 2022 inked a memorandum of understanding with the European Union to develop the energy corridor.

The involved countries are in the process of applying for the cable to be selected as an EU “project of mutual interest,” making it an infrastructure priority for connecting the union with its neighbors. If selected, “the project could qualify for 50 percent grant financing,” says Gachechiladze. “It’s a huge budget. It will improve drastically the financial condition of the project.” The commissioner responsible for EU enlargement policy projected that the union would pay an estimated €2.3 billion ($2.5 billion) toward building the cable.

Whether next week’s COP29, held in Baku, Azerbaijan, will help move the plan forward remains to be seen. In preparation for the conference, advocates of the energy corridor have been taking international journalists on tours of the country’s energy infrastructure.

Looming over the project are the security issues threaten to thwart it. Shipping routes in the Black Sea have become less dependable and safe since Russia’s invasion of Ukraine. To the south, tensions between Armenia and Azerbaijan remain after the recent war and ethnic violence.

In order to improve relations, many advocates of the energy corridor would like to include Armenia. “The cable project is in the interests of Georgia, it’s in the interests of Armenia, it’s in the interests of Azerbaijan,” says Agha Bayramov, an energy geopolitics researcher at the University of Groningen, in the Netherlands. “It might increase the chance of them living peacefully together. Maybe they’ll say, ‘We’re responsible for European energy. Let’s put our egos aside.’”

Equipped with a new behavior architecture, Nadia navigates and traverses many types of doors autonomously. Nadia also demonstrates robustness to failed grasps and door opening attempts by automatically retrying and continuing. We present the robot with pull and push doors, four types of opening mechanisms, and even spring-loaded door closers. A deep neural network and door plane estimator allow Nadia to identify and track the doors.

In this study, we integrate the musculoskeletal humanoid Musashi with the wire-driven robot CubiX, capable of connecting to the environment, to form CubiXMusashi. This combination addresses the shortcomings of traditional musculoskeletal humanoids and enables movements beyond the capabilities of other humanoids. CubiXMusashi connects to the environment with wires and drives by winding them, successfully achieving movements such as pull-up, rising from a lying pose, and mid-air kicking, which are difficult for Musashi alone.

This paper presents a novel learning-based control framework that uses keyframing to incorporate high-level objectives in natural locomotion for legged robots. These high-level objectives are specified as a variable number of partial or complete pose targets that are spaced arbitrarily in time. Our proposed framework utilizes a multi-critic reinforcement learning algorithm to effectively handle the mixture of dense and sparse rewards. In the experiments, the multi-critic method significantly reduces the effort of hyperparameter tuning compared to the standard single-critic alternative. Moreover, the proposed transformer-based architecture enables robots to anticipate future goals, which results in quantitative improvements in their ability to reach their targets.

We present the first static-obstacle avoidance method for quadrotors using just an onboard, monocular event camera. Quadrotors are capable of fast and agile flight in cluttered environments when piloted manually, but vision-based autonomous flight in unknown environments is difficult in part due to the sensor limitations of traditional onboard cameras. Event cameras, however, promise nearly zero motion blur and high dynamic range, but produce a large volume of events under significant ego-motion and further lack a continuous-time sensor model in simulation, making direct sim-to-real transfer not possible.

Cross-embodiment imitation learning enables policies trained on specific embodiments to transfer across different robots, unlocking the potential for large-scale imitation learning that is both cost-effective and highly reusable. This paper presents LEGATO, a cross-embodiment imitation learning framework for visuomotor skill transfer across varied kinematic morphologies. We introduce a handheld gripper that unifies action and observation spaces, allowing tasks to be defined consistently across robots.
