Researchers advance the board engineering pathway to improve power electronics
Atomic power microscopy (AFM) shows the surface of the TAC thin film before and after annealing at high temperatures. The initial film surface is made up of many cylindrical grains, but the annealed surface is reorientated to a plateau or “step terrace.” This flat surface promotes the growth of much higher quality argan layers, thus leading to high-performance electronics.

New insights into Cyclone Way Recovery can help advance predictive models for extreme weather phenomena
(a) SST from AMSR-2 on June 16th, 2023. The green dots indicate the route for Cyclone By Paljoy (obtained from IMD, 2023). (b) Time series of average SST from AMSR-2 from June 1 to May 5, 2023. The ship investigated the wake between June 17th and 20th and is indicated by a cyan marker. The solid line shows the average…

Scientists will advance to produce abundant singga from biomass gas.
The leafy NI/CA3ALO catalyst is used for biomass gas and achieves high stability hydrogen production. Credit: Yin Jiao The production of hydrogen from biomass is gaining attention, and thermal methods have emerged as the most widely adopted approach. Among these, steam gasization stands out as a particularly promising method for producing H2 rich Singa. However, the main challenge related to…

Record-low Antarctic sea ice can be explained by wind patterns and predicted months in advance
Sea ice off the coast of West Antarctica photographed from a research vessel in October 2018. A new study explains and predicts the recent decline in winter sea ice around Antarctica. Credit: Hannah Dawson/University of Washington Amid all the changes in Earth’s climate, the stormy Southern Ocean sea ice surrounding Antarctica has long been a strange exception. Despite rising global…

New model can predict ocean heatwaves and extreme ocean acidity months in advance
Prediction skill of MHW, OAX(Ωa), OAX((H+)). Credit: Nature Geoscience (2024). DOI: 10.1038/s41561-024-01593-0 In the 21st century, the Earth’s oceans are becoming warmer and more acidic. This change occurs slowly over the long term, but can also cause short-term local spikes. These events are like heat waves or days of poor air quality that we experience on land, but only under…

X-rays advance understanding of Earth’s core-mantle boundary and super-Earth magma oceans
Schematic diagram of the experimental setup available at the MEC end station. Four epiX 10k detectors cover the Q range from 15 to 106 nm-1 with an X-ray beam energy of 17 keV. The complete signal can be reconstructed by stitching together the diffuse scattering recorded by each detector. Credit: Nature Communications (2024).

Waterless manufacturing approach could help advance integration of 2D electronics
These materials are made from molybdenum disulfide, a two-dimensional semiconductor, grown on the surface of sapphire. The triangles align because a specialized process called epitaxy allows the material to grow in a pattern that follows the surface it’s grown on. Insulating layers, such as amorphous boron nitride, are added during the manufacturing process of these ultra-thin materials that will be…
