The hydro­thermal synthesis and structural characterization of four novel 3D pillared-layer metal–organic frameworks are studied, revealing how the malleability of copper coordination geometries drives diverse supramolecular isomerism. The findings provide new insights into designing advanced hybrid materials with tailored properties, emphasizing the significant role of reaction conditions and metal ion flexibility in determining network topologies.

In Part I of this series, all topologically possible 1-periodic infinite graphs (chain graphs) representing chains of tetrahedra with up to 6–8 vertices (tetrahedra) per repeat unit were generated. This paper examines possible restraints on embedding these chain graphs into Euclidean space such that they are compatible with the metrics of chains of tetrahedra in observed crystal structures. Chain-silicate minerals with T = Si4+ (plus P5+, V5+, As5+, Al3+, Fe3+, B3+, Be2+, Zn2+ and Mg2+) have a grand nearest-neighbour 〈T–T〉 distance of 3.06±0.15 Å and a minimum T⋯T separation of 3.71 Å between non-nearest-neighbour tetrahedra, and in order for embedded chain graphs (called unit-distance graphs) to be possible atomic arrangements in crystals, they must conform to these metrics, a process termed equalization. It is shown that equalization of all acyclic chain graphs is possible in 2D and 3D, and that equalization of most cyclic chain graphs is possible in 3D but not necessarily in 2D. All unique ways in which non-isomorphic vertices may be moved are designated modes of geometric modification. If a mode (m) is applied to an equalized unit-distance graph such that a new geometrically distinct unit-distance graph is produced without changing the lengths of any edges, the mode is designated as valid (mv); if a new geometrically distinct unit-distance graph cannot be produced, the mode is invalid (mi). The parameters mv and mi are used to define ranges of rigidity of the unit-distance graphs, and are related to the edge-to-vertex ratio, e/n, of the parent chain graph. The program GraphT–T was developed to embed any chain graph into Euclidean space subject to the metric restraints on T–T and T⋯T. Embedding a selection of chain graphs with differing e/n ratios shows that the principal reason why many topologically possible chains cannot occur in crystal structures is due to violation of the requirement that T⋯T > 3.71 Å. Such a restraint becomes increasingly restrictive as e/n increases and indicates why chains with stoichiometry TO<2.5 do not occur in crystal structures.

Analytical calculations of absorption corrections for X-ray powder diffraction experiments on non-ideal samples with surface roughness, porosity or absorption contrasts from multiple phases require complex mathematical models to represent their material distribution. In a computational approach to this problem, a practicable ray-tracing algorithm is formulated which is capable of simulating angle-dependent absorption corrections in reflection geometry for any given rasterized sample model. Single or multiphase systems with arbitrary surface roughness, porosity and spatial distribution of the phases in any combination can be modeled on a voxel grid by assigning respective values to each voxel. The absorption corrections are calculated by tracing the attenuation of X-rays along their individual paths via a modified shear-warp algorithm. The algorithm is presented in detail and the results of simulated absorption corrections on samples with various surface modulations are discussed in the context of published experimental results.

The growth quality of AlN single crystals was improved by optimizing the crucible structure for Al vapor transport with the help of finite element simulation.

A new processing technique for synchrotron scanning 3D X-ray diffraction data is introduced, utilizing symmetric Bragg reflections hkl and hkl, known as Friedel pairs. This technique is designed to tackle the difficulties associated with large, highly deformed, polyphase materials, especially geological samples.

The present study introduces a processing strategy for synchrotron scanning 3D X-ray diffraction (s3DXRD) data, aimed at addressing the challenges posed by large, highly deformed, polyphase materials such as crystalline rocks. Leveraging symmetric Bragg reflections known as Friedel pairs, our method enables diffraction events to be precisely located within the sample volume. This method allows for fitting the phase, crystal structure and unit-cell parameters at the intra-grain scale on a voxel grid. The processing workflow incorporates several new modules, designed to (i) efficiently match Friedel pairs in large s3DXRD datasets containing up to 108 diffraction peaks; (ii) assign phases to each pixel or voxel, resolving potential ambiguities arising from overlap in scattering angles between different crystallographic phases; and (iii) fit the crystal orientation and unit cell locally on a point-by-point basis. We demonstrate the effectiveness of our technique on fractured granite samples, highlighting the ability of the method to characterize complex geological materials and show their internal structure and mineral composition. Additionally, we include the characterization of a metal gasket made of a commercial aluminium alloy, which surrounded the granite sample during experiments. The results show the effectiveness of the technique in recovering information about the internal texture and residual strain of materials that have undergone high levels of plastic deformation.

In the conventional crucible structure for AlN crystal growth by physical vapor transport, owing to the long molecular transport path of Al vapor and the disruption of the gas flow by the presence of a deflector, the Al vapor easily forms polycrystals in the growth domain. The result is increased internal stress in the crystals and increased difficulty in growing large-sized crystals. On this basis, with the help of finite element simulations, a novel crucible structure is designed. This crucible not only optimizes the gas transport but also increases the radial gradient of the AlN crystal surface, making the enhanced growth rate in the central region more obvious. The thermal stresses between the deflector and the crystal are also reduced. High-quality AlN crystals with an FWHM of 79 arcsec were successfully grown with this structure, verifying the accuracy of finite element simulation of the growth of AlN crystals. Our work has important guiding significance for the growth of high-quality AlN crystals.

xrdPlanner is a software package designed to aid in the planning and preparation of powder X-ray diffraction and total scattering beam times at synchrotron facilities. Many modern beamlines provide a flexible experimental setup and may have several different detectors available. In combination with a range of available X-ray energies, it often makes it difficult for the user to explore the available parameter space relevant for a given experiment prior to the scheduled beam time. xrdPlanner was developed to provide a fast and straightforward tool that allows users to visualize the accessible part of reciprocal space of their experiment at a given combination of photon energy and detector geometry. To plan and communicate the necessary geometry not only saves time but also helps the beamline staff to prepare and accommodate for an experiment. The program is tailored toward powder X-ray diffraction and total scattering experiments but may also be useful for other experiments that rely on an area detector and for which detector placement and achievable momentum-transfer range are important experimental parameters.

UPDATE: “Allegiance” will be performed Feb. 21-April 1, 2018, at the Aratani Theater at the Japanese Cultural and Community Center in downtown L.A.'s Little Tokyo.

ORIGINAL STORY: In an intimate interview, George Takei tells Off-Ramp host John Rabe about crafting the Japanese-American internment camp history into compelling Broadway musical theater. "Allegiance," with Takei, Lea Salonga and Telly Leung, played at the Longacre Theater.

George Takei and his husband Brad were putting their house in mothballs when I arrived for our interview in August. They'd already been spending a lot of time in New York because of George's recurring role on "The Howard Stern Show," but now, with the Broadway opening of "Allegiance" just a couple months away, they were preparing to move for as long as the musical brings in the crowds.

While Brad went off to deal with the mundane domestic tasks around the move, I sat with George in their living room to talk about turning one of America's most shameful episodes — the internment of some 120,000 loyal Japanese-Americans during World War II — into a musical that could make it on the Broadway stage.

George, you just sent an email to your fans with the subject line: "I've Waited 7 Years to Send You this Email. Seven years!" Inside, you wrote: "Few things are as difficult and complex as taking a show to ‪Broadway‬. It's both thrilling and terrifying." What was terrifying?

"The terrifying part is, you've poured your passion, your energy, your resources ...  you make all that investment in that project, and then you're hoping the seats are going to be filled.That 'what if' is terrifying. But in San Diego, we had a sold-out run and broke their 77-year record. But now we're going to Broadway, and that same fear is there. Will they come? What will the critics say? Because it's life or death."

It took a long time just to get a Broadway theater.

"It took a long time to get a theater.You think there are a lot of Broadway theaters, but there are even more productions that want those chunks of New York real estate. So we thought we'd get in line. But then the other discovery we made is that the theater owners have relationships with grizzled old producers who have brought them a vast fortune with enormous hits, and they can cut in line. They have a track record. And so, 'will we ever get a theater' became a big question. But we have this time now — let's use it creatively, productively."

So, Takei says, the team tweaked the show, removing parts that didn't work didn't advance the story, inserting numbers that worked better and kept the story moving. They doubled down on social media, building and proving demand in the show.

"We have a Shubert theater (the Longacre), and Bob Wankel is head guy there, and I remember pouring my heart out, telling the story of my parents, hoping that touches. And he was understanding, but I understood his problem, too. Everybody is trying to get a theater and he has to make a good business decision and was initially skeptical. An internment camp musical? But music has the power to make an anguished painful situation even more moving, even more powerful. It hits you in the heart."

This is your Broadway debut, right? Are you petrified?

"Yes, yes. I've done a lot of stage work, and I've done a lot of public speaking, but it's Broadway, and I'm a debutante... at 78 years old! And it's the critics, too. The New York Times, Ben Brantley. That's who I'm going to be facing, and so it's both exciting and absolutely filling me with ecstasy, but what makes it ecstatic is the fear."

Geologic mapping has been one of the most fundamental mandates of the U.S. Geological Survey (USGS) since its establishment in 1879. Congress created the USGS to "classify the public lands and examine the geological structure, mineral resources, and products within and outside the national domain."

A new study from USGS describes a previously unknown process of marine mineral formation in the Arctic Ocean, driven by frictional heating along tectonic faults rather than by hydrothermal activity.

Attorney General Merrick Garland announced Friday that the U.S. Justice Department is suing the state of Georgia over its new voting law, saying that the controversial measure is intended to restrict ballot access to Black voters.

"Our complaint alleges that recent changes to Georgia's election laws were enacted with the purpose of denying or abridging the right of Black Georgians to vote on account of their race or color, in violation of Section 2 of the Voting Rights Act," Garland said at a news conference.

The lawsuit marks the first major action from the Biden administration to combat a series of new restrictive voting measures passed by Republican-led state legislatures. And it came on the eighth anniversary of the U.S. Supreme Court decision to gut another key provision of the landmark Voting Rights Act, Section 5.

Garland noted that Georgia experienced record voter turnout and participation in the 2020 election cycle.

In March, Georgia Gov. Brian Kemp, a Republican, signed Senate Bill 202, a 98-page omnibus measure that makes sweeping changes to the state's absentee voting rules, adds new voter identification mandates and nearly cuts in half the amount of time for voters to request a mail-in ballot. It also expands early voting access for most counties and formally codifies Sunday voting hours as optional.

The legislation outlaws passing out food or drinks to voters within 150 feet of a polling place or too close to voters waiting in line, a provision that Assistant Attorney General Kristen Clarke, who heads the department's Civil Rights Division, highlighted at the press conference.

"Historically, minority voters in Georgia have been disproportionately more likely to wait in long lines to vote in person on Election Day," she said. "Given those long and protracted wait times, civic groups, including churches, have at times provided food and water to voters in line to make their wait more comfortable. As we allege in our complaint, this needless ban was passed with unlawful discriminatory intent."

Clarke also said the Georgia Legislature passed the bill through "a rushed process that departed from normal practice and procedure."

"The version of the bill that passed the state Senate ... was three pages long. Days later, the bill ballooned into over 90 pages in the House. The House held less than two hours of floor debate on the newly inflated SB 202 before Gov. Kemp signed it into law the same day," she said. "These legislative actions occurred at a time when the Black population in Georgia continues to steadily increase, and after a historic election that saw record voter turnout across the state, particularly for absentee voting, which Black voters are now more likely to use than white voters."

Garland said the lawsuit is the first of "many steps" the department is taking to protect the right to vote for all eligible voters. He said the Civil Rights Division will continue to examine voting laws that other states have passed.

"We will not hesitate to act," Garland said.

The Justice Department announced this month it would vigorously defend voting rights. Garland said that the department will double the number of voter enfranchisement lawyers and focus attention on litigation related to voting rights.

In response to the filing, Kemp said the lawsuit is "born out of the lies and misinformation the Biden administration has pushed against Georgia's Election Integrity Act from the start."

"[Biden and his allies] are weaponizing the U.S. Department of Justice to carry out their far-left agenda that undermines election integrity and empowers federal government overreach in our democracy," he said in a statement.

Georgia Secretary of State Brad Raffensperger, another Republican who notably defended the state's administration of the 2020 election, said in a statement he "looks forward to ... beating [the administration] in court."

Garland's announcement comes just days after Senate Republicans united to block Democrats' attempts to pass sweeping voting rights legislation.

Senate Judiciary Chairman Dick Durbin, D-Ill., tweeted his approval of the lawsuit shortly after the announcement Friday.

"If Republicans think the fight for voting rights ended with their filibuster of the For the People Act, they are sorely mistaken," he wrote. "Glad to see the Biden Administration is joining this effort. We must protect our democracy."

The Republican National Committee also linked the failed Senate vote to the Department of Justice's lawsuit.

"After failing to sell the partisan federal election takeover known as H.R. 1 to the American people, Joe Biden is now weaponizing the Justice Department to attack election integrity," RNC Chair Ronna McDaniel said in a statement.

George R.R. Martin has entered into a five year deal with HBO to develop content for both HBO and HBO Max, the network said in a statement on Monday.

The best-selling fantasy author and four-time Emmy award winner, best known for his book series A Song of Ice and Fire and its television adaptation Game of Thrones, is attached to multiple projects in the pipeline for the media company and streaming service.

The Game of Thrones television series followed powerful families aiming for the iron throne in the continent of Westeros. It ran for eight years on HBO, with the final season wrapping in 2019.

Martin has a new drama series in the works, House of the Dragon, which is based on his Fire & Blood book. The Game of Thrones prequel follows House Targaryen and is set 300 years before the events of Game of Thrones.

The show has been given a ten episode order. Paddy Considine, Olivia Cooke, Matt Smith, and Emma D'Arcy have joined the series, with additional cast members to be announced.

The show is co-created by Martin and Ryan Condal, whose prior work includes Colony, Rampage, and Hercules. Condal and Miguel Sapochnik (Game of Thrones, Altered Carbon) serve as showrunners and producers with Martin and Vince Gerardis (Game of Thrones).

Martin is also set to executive produce HBO's Who Fears Death, a fantasy post-apocalyptic series with Tessa Thompson attached to star and adapted from the novel by Nnedi Okorafor; and Roadmarks, an adaptation of the sci-fi novel from Roger Zelazny.

Eleven questions that should shape the next decade of geographical sciences research were identified today in a new report by the National Research Council.

A new report from the National Academies of Sciences, Engineering, and Medicine says that enhancements to the geodetic infrastructure are needed to answer important questions about sea level rise, water resources, geological hazards, and more over the next decade.

Given the urgency of the risks posed by climate change, the U.S. should pursue a research program for solar geoengineering — in coordination with other nations, subject to governance, and alongside a robust portfolio of climate mitigation and adaptation policies, says a new report from the National Academies of Sciences, Engineering, and Medicine.
