Tesla has been building Prefabricated Supercharger Units (PSUs) for at least a year at its Giga New York facility, and now the company released a video claiming it can deploy the pre-built EV fast chargers in just four days after getting them delivered to the installation site.

The company’s PSUs have up to four Supercharger stalls installed on a concrete base, with all the wiring in place and everything ready to be hooked up to the utilities. Up to three units–that’s 12 stalls in total–can be loaded onto the back of a truck with a crane and delivered to a new Supercharger location in the United States.

“Our research is inspired by the idea that unconventional superconductivity usually emerges in proximity to magnetism,” Xiang said. “In particular, for copper-based and iron-based , many of the proposed superconducting pairing mechanisms are closely connected to magnetism; moreover, the interplay between magnetism and superconductivity may give birth to more peculiar phases of matter, including the pair-density-wave (PDW) order with a spatially oscillating superconducting order parameter and finite-momentum pairing which has been an intense focus of research recently.”

The EuO/KTO heterostructure examined by Xiang and his colleagues exhibits a strong ferromagnetic proximity effect elicited by the EuO overlayer. This effect makes it an ideal platform to study unconventional superconductivity.

“The first report on the superconductivity at the EuO/KTO interface was published in 2021, focusing on the KTO (111) interface,” Xiang said. “We have since worked on the EuO/KTO (110) interface (considering its improved interface quality), at which we revealed the emergence of two-dimensional superconductivity in a previous paper.”

Nuclear nonproliferation scientists at the Department of Energy’s Oak Ridge National Laboratory have published the Compendium of Uranium Raman and Infrared Experimental Spectra, or CURIES, a public database and analysis of structure-spectral relationships for uranium minerals. This first-of-its-kind dataset and corresponding analysis fill a key gap in the existing body of knowledge for mineralogists and actinide scientists.

Laser based vibrational spectroscopy methods such as Raman and IR are frequently employed by nonproliferation materials scientists because they are rapid, nominally non-destructive, and can give direct insight to what a material contains. Where spectral assignments may be difficult, the CURIES database uses structural information, subject matter expertise and statistical analysis to determine key features of Raman spectra based on their structural origins.

“When I was in grad school studying uranium mineralogy, there was no single repository to look up a feature of a sample and compare it for identification,” said ORNL’s Tyler Spano, lead author on the CURIES article in American Minerologist. “What we did was bring together data from many different sources including structural information and spectroscopy to understand spectral features and similarities as they relate to chemical, structural and other properties.” The ORNL team hopes that CURIES will support researchers who are looking for new relationships among various types of uranium materials and foster development of rapid characterization and analysis of spectra collected on new materials.

A team of MIT researchers has addressed significant barriers to the practical application of 2D magnetic materials. This innovation will enable the development of the next generation of energy-efficient computers.

The team achieved a notable breakthrough by developing a “van der Waals atomically layered heterostructure” device. The device connects two 2D materials: tungsten ditelluride and iron gallium telluride, a 2D van der Waals magnet.

MAWI United, a studio specializing in creating lifelike 3D environments, has once again pushed photorealism to the next level by presenting Dead Spruce Forest Tree Biome, a new procedural environment asset pack that lets you create AAA-quality forests in Unreal Engine 5.

Featuring over 200 photogrammetry-made plant, debris, and tree assets, as well as full Nanite support, the pack has everything you need to build next-level environments for your games and projects. As usual, MAWI’s latest creation comes with tools for procedural forest generation and interactive foliage and an advanced ground material with five different surface types (forest, meadow, wetland, stones, dirt) that automatically generates all the small ground cover and foliage.

Anthropogenic plastic pollution is often experienced through evocative images of marine animals caught in floating debris, yet its reach is far more expansive. The polar regions of the Arctic and Antarctica are increasingly experiencing the impacts of plastic reaching floating ice and land, not solely as larger macroplastics (>5 cm), but as microplastics (0.1 µm—5 mm) and nanoplastics (<0.1 µm) that may be carried vast distances from their source or be ingested in more populated areas during seasonal migration.

Using sugarcane waste as bricks for construction.

Architecture studio Grimshaw and the University of East London have collaborated to create Sugarcrete, a biomaterial construction block with an interlocking shape made from the sugarcane by-product bagasse.

Sugarcrete was developed to be a low-cost and low-carbon reusable construction-material alternative to brick and concrete.

The concept, design and fabrication of the material were led by staff and fellows of the University of East London (UEL), including senior architecture lecturer Armor Gutierrez Rivas, Sustainability Research Institute co-director Alan Chandler and research fellow Bamdad Ayati.
