Supramolecular synthons in hydrates and solvates of lamotrigine: a tool for cocrystal design

The molecule of anti-epileptic drug lamotrigine [LAM; 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine] is capable of the formation of multicomponent solids. Such an enhanced tendency is related to the diverse functionalities of the LAM chemical groups able to form hydrogen bonds. Two robust synthons are recognized in the supramolecular structure of LAM itself formed via N—H⋯N hydrogen bond: homosynthon, so-called aminopyridine dimer or synthon 1 [R22(8)] and larger homosynthon 2 [R32(8)]. The synthetic procedures for a new hydrate and 11 solvates of LAM (in the series: with acetone, ethanol: two polymorphs: form I and form II, 2-propanol, n-butanol, tert-butanol, n-pentanol, benzonitrile, acetonitrile, DMSO and dioxane) were performed. The comparative solid state structural analysis of a new hydrate and 11 solvates of LAM has been undertaken in order to establish robustness of the supramolecular synthons 1 and 2 found in the crystal structure of LAM itself as well as LAM susceptibility to build methodical solid state supramolecular architecture in the given competitive surrounding of potential hydrogen bonds. The aminopyridine dimer homosynthon 1 [R22(8)] has been switched from para-para (P-P) topology to ortho-ortho (O-O) topology in all crystal structures, except in LAM:n-pentanol:water solvate where it remains P-P. Homosynthon 2 [R32(8)] of the LAM crystal structure imitates in the LAM solvates as a heterosynthon by replacing the triazine nitrogen proton acceptor atoms of LAM with the proton acceptors of solvates molecules.

Fast nanoscale imaging of strain in a multi-segment heterostructured nanowire with 2D Bragg ptychography

Developing semiconductor devices requires a fast and reliable source of strain information with high spatial resolution and strain sensitivity. This work investigates the strain in an axially heterostructured 180 nm-diameter GaInP nanowire with InP segments of varying lengths down to 9 nm, simultaneously probing both materials. Scanning X-ray diffraction (XRD) is compared with Bragg projection ptychography (BPP), a fast single-projection method. BPP offers a sufficient spatial resolution to reveal fine details within the largest segments, unlike scanning XRD. The spatial resolution affects the quantitative accuracy of the strain maps, where BPP shows much-improved agreement with an elastic 3D finite element model compared with scanning XRD. The sensitivity of BPP to small deviations from the Bragg condition is systematically investigated. The experimental confirmation of the model suggests that the large lattice mismatch of 1.52% is accommodated without defects.

Phase-contrast neutron imaging compared with wave propagation and McStas simulations

Propagation-based phase contrast, for example in the form of edge enhancement contrast, is well established within X-ray imaging but is not widely used in neutron imaging. This technique can help increase the contrast of low-attenuation samples but may confuse quantitative absorption measurements. Therefore, it is important to understand the experimental parameters that cause and amplify or dampen this effect in order to optimize future experiments properly. Two simulation approaches have been investigated, a wave-based simulation and a particle-based simulation conducted in McStas [Willendrup & Lefmann (2020). J. Neutron Res. 22, 1–16], and they are compared with experimental data. The experiment was done on a sample of metal foils with weakly and strongly neutron absorbing layers, which were measured while varying the rotation angle and propagation distance from the sample. The experimental data show multiple signals: attenuation, phase contrast and reflection. The wave model reproduces the sample attenuation and the phase peaks but it does not reproduce the behavior of these peaks as a function of rotation angle. The McStas simulation agrees better with the experimental data, as it reproduces attenuation, phase peaks and reflection, as well as the change in these signals as a function of rotation angle and distance. This suggests that the McStas simulation approach, where the particle description of the neutron facilitates the incorporation of multiple effects, is the most convenient way of modeling edge enhancement in neutron imaging.

Demonstration of neutron time-of-flight diffraction with an event-mode imaging detector

Neutron diffraction beamlines have traditionally relied on deploying large detector arrays of 3He tubes or neutron-sensitive scintillators coupled with photomultipliers to efficiently probe crystallographic and microstructure information of a given material. Given the large upfront cost of custom-made data acquisition systems and the recent scarcity of 3He, new diffraction beamlines or upgrades to existing ones demand innovative approaches. This paper introduces a novel Timepix3-based event-mode imaging neutron diffraction detector system as well as first results of a silicon powder diffraction measurement made at the HIPPO neutron powder diffractometer at the Los Alamos Neutron Science Center. Notably, these initial measurements were conducted simultaneously with the 3He array on HIPPO, enabling direct comparison. Data reduction for this type of data was implemented in the MAUD code, enabling Rietveld analysis. Results from the Timepix3-based setup and HIPPO were benchmarked against McStas simulations, showing good agreement for peak resolution. With further development, systems such as the one presented here may substantially reduce the cost of detector systems for new neutron instrumentation as well as for upgrades of existing beamlines.

Coherent X-ray diffraction imaging of single particles: background impact on 3D reconstruction

Coherent diffractive imaging with X-ray free-electron lasers could enable structural studies of macromolecules at room temperature. This type of experiment could provide a means to study structural dynamics on the femtosecond timescale. However, the diffraction from a single protein is weak compared with the incoherent scattering from background sources, which negatively affects the reconstruction analysis. This work evaluates the effects of the presence of background on the analysis pipeline. Background measurements from the European X-ray Free-Electron Laser were combined with simulated diffraction patterns and treated by a standard reconstruction procedure, including orientation recovery with the expand, maximize and compress algorithm and 3D phase retrieval. Background scattering did have an adverse effect on the estimated resolution of the reconstructed density maps. Still, the reconstructions generally worked when the signal-to-background ratio was 0.6 or better, in the momentum transfer shell of the highest reconstructed resolution. The results also suggest that the signal-to-background requirement increases at higher resolution. This study gives an indication of what is possible at current setups at X-ray free-electron lasers with regards to expected background strength and establishes a target for experimental optimization of the background.

Low-dose electron microscopy imaging for beam-sensitive metal–organic frameworks

Metal–organic frameworks (MOFs) have garnered significant attention in recent years owing to their exceptional properties. Understanding the intricate relationship between the structure of a material and its properties is crucial for guiding the synthesis and application of these materials. (Scanning) Transmission electron microscopy (S)TEM imaging stands out as a powerful tool for structural characterization at the nanoscale, capable of detailing both periodic and aperiodic local structures. However, the high electron-beam sensitivity of MOFs presents substantial challenges in their structural characterization using (S)TEM. This paper summarizes the latest advancements in low-dose high-resolution (S)TEM imaging technology and its application in MOF material characterization. It covers aspects such as framework structure, defects, and surface and interface analysis, along with the distribution of guest molecules within MOFs. This review also discusses emerging technologies like electron ptychography and outlines several prospective research directions in this field.

Development of crystal optics for X-ray multi-projection imaging for synchrotron and XFEL sources

X-ray multi-projection imaging (XMPI) is an emerging experimental technique for the acquisition of rotation-free, time-resolved, volumetric information on stochastic processes. The technique is developed for high-brilliance light-source facilities, aiming to address known limitations of state-of-the-art imaging methods in the acquisition of 4D sample information, linked to their need for sample rotation. XMPI relies on a beam-splitting scheme, that illuminates a sample from multiple, angularly spaced viewpoints, and employs fast, indirect, X-ray imaging detectors for the collection of the data. This approach enables studies of previously inaccessible phenomena of industrial and societal relevance such as fractures in solids, propagation of shock waves, laser-based 3D printing, or even fast processes in the biological domain. In this work, we discuss in detail the beam-splitting scheme of XMPI. More specifically, we explore the relevant properties of X-ray splitter optics for their use in XMPI schemes, both at synchrotron insertion devices and XFEL facilities. Furthermore, we describe two distinct XMPI schemes, designed to faciliate large samples and complex sample environments. Finally, we present experimental proof of the feasibility of MHz-rate XMPI at the European XFEL. This detailed overview aims to state the challenges and the potential of XMPI and act as a stepping stone for future development of the technique.

X-ray ghost imaging with a specially developed beam splitter

X-ray ghost imaging with a crystal beam splitter has advantages in highly efficient imaging due to the simultaneous acquisition of signals from both the object beam and reference beam. However, beam splitting with a large field of view, uniform distribution and high correlation has been a great challenge up to now. Therefore, a dedicated beam splitter has been developed by optimizing the optical layout of a synchrotron radiation beamline and the fabrication process of a Laue crystal. A large field of view, consistent size, uniform intensity distribution and high correlation were obtained simultaneously for the two split beams. Modulated by a piece of copper foam upstream of the splitter, a correlation of 92% between the speckle fields of the object and reference beam and a Glauber function of 1.25 were achieved. Taking advantage of synthetic aperture X-ray ghost imaging (SAXGI), a circuit board of size 880 × 330 pixels was successfully imaged with high fidelity. In addition, even though 16 measurements corresponding to a sampling rate of 1% in SAXGI were used for image reconstruction, the skeleton structure of the circuit board can still be determined. In conclusion, the specially developed beam splitter is applicable for the efficient implementation of X-ray ghost imaging.

A study of structural effects on the focusing and imaging performance of hard X-rays with 20–30 nm zone plates

Hard X-ray microscopes with 20–30 nm spatial resolution ranges are an advanced tool for the inspection of materials at the nanoscale. However, the limited efficiency of the focusing optics, for example, a Fresnel zone plate (ZP) lens, can significantly reduce the power of a nanoprobe. Despite several reports on ZP lenses that focus hard X-rays with 20 nm resolution – mainly constructed by zone-doubling techniques – a systematic investigation into the limiting factors has not been reported. We report the structural effects on the focusing and imaging efficiency of 20–30 nm-resolution ZPs, employing a modified beam-propagation method. The zone width and the duty cycle (zone width/ring pitch) were optimized to achieve maximum efficiency, and a comparative analysis of the zone materials was conducted. The optimized zone structures were used in the fabrication of Pt-hydrogen silsesquioxane (HSQ) ZPs. The highest focusing efficiency of the Pt-HSQ-ZP with a resolution of 30 nm was 10% at 7 keV and >5% in the range 6–10 keV, whereas the highest efficiency of the Pt-HSQ-ZP with a resolution of 20 nm was realized at 7 keV with an efficiency of 7.6%. Optical characterization conducted at X-ray beamlines demonstrated significant enhancement of the focusing and imaging efficiency in a broader range of hard X-rays from 5 keV to 10 keV, demonstrating the potential application in hard X-ray focusing and imaging.

The Cosby Show at 30: Changing the face of black America

The original cast of The Cosby Show. ; Credit: Frank Carroll/Associated Press

Thirty years ago, on September 20,"The Cosby Show" debuted on NBC and went on to dominate our screens for almost a decade.

The award-winning sitcom introduced us to the Huxtables, an upper-middle class black family  made up of Heathcliff, Clair and their five children. Plus a cast of ugly sweaters.

"The Cosby Show" covered familiar territory; from children getting body piercings, bad boyfriends and maintaining a long term relationship as parents with professional lives.

Speaking to Take Two's Alex Cohen, Mark Anthony Neal, professor of African and African American Studies at Duke University said "The Cosby Show" broke down racial stereotypes.

"It  really was the first program to present not just a middle class, or upper-middle class black family, but a professional family. Clair and Heathcliff Huxtable were educated, they had advanced degrees. It was an image we hadn't seen before."

 

From 1985 to 1990, "The Cosby Show" held the number one spot in the TV ratings war, appealing to audiences across color lines. Black viewers in particular welcomed a broader representation of African American life on screen, building on the success of shows such as "The Jeffersons", "Sanford and Son" and "Good Times". 

"Bill Cosby was very honest about the fact that when he conceived the character of Heathcliff Huxtable, he was looking for images that countered, say, Fred Sanford who was a junk dealer, or James Evans, Jr. in 'Good Times' who was always struggling to find a job. Bill Cosby wanted to bring a different view of the black family into the mix."

Despite its popularity, some people took issue with how "The Cosby Show" tackled race issues.

"It's not that black Americans didn't enjoy the show, but there were criticisms because it didn't explore the broader world of African Americans." says Professor Neal. "The Huxtable family became a stand in for the successes of the civil rights movement. It became the rationale that if the Huxtables can do it, why can't other African Americans do it?"

Today's media landscape is very different to the one "The Cosby Show" existed in. For this reason, says Professor Neal, its success has been difficult to replicate.

"Right after it went off the air, cable TV takes hold and we get this niche programming.  Many African American programs ended up on Fox, UPN and the WB, so there was no incentive for the major networks to do any Cosby-like programming with a black family at the center."

With the debut of ABC's "Blackish" on September 24, it's hoped this will go some way to fill the Cosby-shaped void. In the meantime there's always YouTube and re-runs. Just be thankful Heathcliff's ugly sweaters are a thing of the past.

Engineering Milestone Secures Progress for Key Lithium Project in Brazil

Source: Streetwise Reports 10/23/2024

Lithium Ionic Corp. (LTH:TSX.V; LTHCF:OTCQX; H3N:FSE) has announced the initiation of Engineering, Procurement, and Construction Management (EPCM) services for its flagship Bandeira Lithium Project. See why the CEO Blake Hyland says that the company's momentum towards production is stronger than ever.

Lithium Ionic Corp. (LTH:TSX.V; LTHCF:OTCQX; H3N:FSE) has announced the initiation of Engineering, Procurement, and Construction Management (EPCM) services for its flagship Bandeira Lithium Project in Minas Gerais, Brazil. Globally recognized engineering firm Hatch Ltd. will lead engineering and design services. Reta Engenharia, a leading Brazilian construction management firm, will manage construction. This significant milestone signals the project's progression into the construction and development phase as Lithium Ionic moves closer to production.

Key Highlights from the company press release:

  • Hatch Ltd. has been awarded engineering and design services. Hatch is an internationally recognized engineering firm with extensive global experience in several commodities and a local presence in Brazil, including offices in Belo Horizonte, the capital city of Minas Gerais state. Hatch's involvement will bring world-class expertise and innovative solutions to the Bandeira Project, ensuring a streamlined and efficient development process.
  • Reta Engenharia, a leading Brazilian construction management company, has been selected to provide construction management services for the Bandeira Project. With extensive experience in greenfield mining projects, Reta has supported both junior and large-cap producers, making them ideally suited to drive efficient and effective project outcomes. Their proven track record in managing greenfield projects, combined with their deep regional knowledge, will be instrumental in advancing the Bandeira Project towards production.
  • Growing the Owner's Team: To support this transition to project development and ensure a smooth transition into production, Lithium Ionic is expanding the technical capabilities of its owner's team by bringing in experienced professionals to guide the Bandeira Project through the construction and operational readiness phases.

In the company's news release, Blake Hylands, CEO of Lithium Ionic, noted the importance of this transition, "Our momentum towards production is stronger than ever as we kick off the engineering and construction management phase with our esteemed partners, Hatch and Reta."

The Bandeira Project is advancing through the permitting process at both state and federal levels, with key approvals expected soon. Initial production is scheduled to begin in the second half of 2026, following the approval of the Licença Ambiental Concomitante (LAC) and subsequent Mining Concession and Operating License.

Lithium Sector Gains Momentum Amid Growing Demand

Visual Capitalist reported on September 29 that despite the price drop, lithium-ion battery demand is projected to increase ninefold by 2040. This move is driven by the continued growth of the EV market and broader electrification trends.

Greg Jones of BMO Capital Markets described new drill results from the Bandeira project as continuing to "highlight the exploration potential at the property" and suggested that these results could present opportunities for optimization.

This long-term growth trajectory supports the ongoing development of lithium projects like Lithium Ionic's Bandeira Project in Brazil, which aims to meet this increasing global demand.

As Forbes reported on October 8, lithium prices had fallen by nearly 90% since their peak in 2022.

This is attributed to an oversupply of the commodity and slower-than-expected electric vehicle (EV) sales. Despite these challenges, industry experts indicated that the sector was showing early signs of recovery.

Also, on October 8, Barry Dawes of Martin Place Securities highlighted that "the lithium market is showing strong signs of upturn" and suggested that lithium shortages are likely after 2027, reinforcing the long-term potential of the sector. His comments reflected a growing optimism for the post-2027 period. It is then that demand for lithium is expected to outstrip supply.

Lithium Ionic's Catalysts

Lithium Ionic's Bandeira Project is positioned as a critical development in Brazil's Lithium Valley. According to the company's investor presentation, this project is expected to deliver significant output. A Feasibility Study projects a 14-year mine life, producing 178,000 tonnes of spodumene concentrate annually. The post-tax net present value (NPV) is projected at US$1.3 billion with an internal rate of return (IRR) of 40%.

The company's strategic partnerships with Hatch and Reta, combined with the strong regional infrastructure in Minas Gerais, which includes renewable hydroelectric power and proximity to export markets, are expected to accelerate the development of the project. These factors are key drivers of Lithium Ionic's goal to become one of Brazil's major lithium producers, contributing to the growing global demand for lithium in the electric vehicle market.

Analysts on Lithium Ionic

Analysts have shown optimism about Lithium Ionic Corp., particularly regarding the potential of its Bandeira Lithium Project. Katie Lachapelle from Canaccord Genuity, in her September 10, 2024, research note, highlighted the company's progress in securing approvals for the Final Exploration Reports for the Bandeira and Outro Lado lithium properties.

Lachapelle emphasized that the next major catalyst would be the approval of the Licença Ambiental Concomitante (LAC), which is needed to begin construction at the Bandeira project. She maintained a Speculative Buy rating with a target price of CA$2.50, representing a potential upside of 303% from the price at the time of the report. Lachapelle also noted the company's CA$35 million cash balance following recent financing transactions but indicated that additional funds would be required to cover the estimated US$266 million in initial capital costs.

On October 8, 2024, Greg Jones of BMO Capital Markets provided further positive insights into Lithium Ionic's development. He described new drill results from the Bandeira project as continuing to "highlight the exploration potential at the property" and suggested that these results could present opportunities for optimization. Jones maintained an Outperform rating on the stock, with a target price of CA$1.25, reflecting a 40% potential return. He also emphasized that the company traded below the peer median, with its lithium carbonate equivalent valued at US$40 per ton, compared to US$60 for peers, marking it as undervalued. He further pointed out that Lithium Ionic was one of BMO's preferred lithium developers. [OWNERSHIP_CHART-11098]

Queena Kim, Off-Ramp's first producer, sheds light on the show's beginnings

Off-Ramp producer Queena Kim acts on behalf of millions of Angelenos. The meter didn't stand a chance.

John Rabe | Off-Ramp®

Off-Ramp began eleven years ago, just as digital technology was beginning to overtake radio. No more cassette tape or mini-discs; host John and producer Queena Kim thought they could take on all of Los Angeles with two digital audio recorders and a different approach to public radio.

Short-handed as they were, John and Queena had to adopt slash-and-burn tactics to get each show produced on time. The majority of interviews were conducted in the field; at the homes, workplaces, and favorite hang-outs of their subjects (instead of waiting for guests to come to the station) and many of the stories were edited as simple two-way interviews with life in Southern California picked up as ambient, background noise. After all, a show called Off-Ramp had better be ready to brave some LA traffic.

At this juncture, John feels free to say what he has always wanted to, but hasn't for fear of self-aggrandizement: "I think we were trendsetters. I think Marketplace and NPR heard the stuff we were doing, and started doing stuff like it." Once again, Kim chalks it up to being in the right place at the right time technologically, and the two person team's willingness to break out of the old-school, public radio way writing a story: with a very clear sonic difference between studio narration and field audio.

Of course, it wasn't just Marantz recorders and minimal rewriting that gave Off-Ramp its flavor. There was a whole lot of weird spewing up out of Los Angeles during the show's formative years and Kim's tenure (2006-2010). She recalls covering a ten-theremin orchestra at Disney Hall, and the excitement of working on a show that let her (and the listeners, vicariously) do things she always wanted to do. "It was almost like having a free pass to the city."

In order to capture what was new and exciting, John and Queena both agree that it was absolutely vital to abandon the reporter's instinct for safely packaging the story ahead of time. John cites his editor at Minnesota Public Radio's philosophy, Mike Edgerly; "Go find what the story is, go out and explore and figure out what the story is. Don't figure it out at your desk first." The collaboration between John's ideas and Kim's sense of logistics formed a dialectic relationship, valuing the "third, better idea" over either of their original perspectives. In light of that, John says Queena Kim was the perfect person with whom to start Off-Ramp.

A new survey shows that in the era of widespread vaccine availability, American couples are more satisfied in their relationships -- and some are even getting more experimental than they have been.

Led by Indiana University Kinsey Institute researcher Justin Lehmiller in collaboration with the website Lovehoney, which describes itself as “global sexual happiness experts,” the report looked at responses from 2,000 U.S. adults age 18-45, including an oversample of 200 who identified as LGBTQ, and among the major findings of the survey were that more than half (51 percent) of respondents said their sexual interests had changed during the pandemic, and many of those said they’d started trying things they hadn’t before. It also found that 44 percent of people surveyed said they were communicating better with their partner, and among singles surveyed 52 percent say they’re less interested in casual sex and more than a third of them said they weren’t interested in having sex on the first date.

Today on AirTalk, we’ll talk with Professor Lehmiller about the survey, its findings and how the pandemic impacted Americans’ views on relationships and sex.

Dominique Maria Bonessi | NPR

Jury selection in the trial of the gunman who fatally shot five employees at the Capital Gazette newspaper in Annapolis, Md., on June 28, 2018 gets underway on Wednesday.

Jarrod Ramos, 41, has pleaded guilty — but not criminally responsible for reason of insanity — in the killings of John McNamara, Rob Hiaasen, Gerald Fischman, Wendi Winters and Rebecca Smith. The mass shooting was one of the deadliest attacks on journalists in modern U.S. history.

"There is a sense that you don't want this to be the thing that makes your life change," Phil Davis, the paper's former criminal justice reporter who now works at the Baltimore Sun, told NPR.

Davis was hiding under his desk while live tweeting the shooting that day. Later, he was part of the Pulitzer Prize-winning team that put out a paper the very next day.

"That's kind of what drove me to continue as a criminal justice reporter. Once I got the feeling of like, 'no we're going to get back to exactly what we do. We're going to tackle this how we would even if it wasn't us and try to go at it from the perspective of a local community newspaper,'" Davis said.

Bruce Shapiro, the executive director of the Columbia University's Dart Center for Journalism and Trauma, said what made this shooting reverberate in newsrooms across the U.S. was "the idea of a newsroom full of colleagues being murdered just because they are journalists. It's an identity based attack."

Attacks on journalists in the U.S. haven't stopped there. During his time in office, President Donald Trump tweeted that the news media is the enemy of the people. Associated Press journalists were threatened and had their equipment damaged by supporters of Trump during the Capitol insurrection on Jan. 6. And last year, during the protests in Minneapolis over the murder of George Floyd by police, the U.S. Press Freedom Tracker reported at least 160 threats to journalists across the country in one week--mostly by police.

Shapiro says the trial is a reminder to the public of the risks and costs local reporters take daily.

"The reality is that local newsrooms all over the country cover extraordinarily difficult events affecting their own families, neighbors, kids, schools whether that is wildfires, whether that is mass shooting, whether that is COVID-19," Shapiro said.

The Capital Gazette trial has been delayed several times due to COVID-19, turnover in the public defender and state's attorney's offices, and rounds of court hearings. Davis says he hopes the long-awaited trial brings some closure.

"Certainly for the families of the victims themselves, I look forward to being on the other end of this trial," he said. "And whatever the outcome is, being able to embrace them and support them just to bring them some sort of closure."

Today, less than a week before the third anniversary of the shooting, the judge has called a pool of 300 people to determine the 12 that will sit as jurors. They will then determine Ramos's mental sanity during the attack.

Steve Mercer, a former Maryland public defender, said the defense has the burden to prove Ramos's sanity. He said that in cases like these, the defense will look at motive and intent. One possible motive, Mercer says, is Ramos' "long-simmering feud with the paper."

Ramos sued the paper for defamation in 2012 after reporters wrote about his guilty plea on charges of criminal harassment and 90-day suspended jail sentence. But that motive might not hold up.

"I think there's a big gap between sort of being upset about a story that's published ... and then going in and committing a mass shooting," Mercer said.

Mercer adds what presents a challenge to both the defense and prosecution is Ramos's conduct after the shooting. He was found by police under a desk at the scene of the shooting with a pump-action shotgun which was purchased legally a few years before.

"The defense may point to it and say that it shows just a disconnect from reality and a lack of awareness of what was going on," Mercer said.

Circuit Court Judge Judge Michael Wachs will ultimately decide if he ends up in prison or a state psychiatric hospital.
