Our high-speed, high-bandwidth world constantly requires new ways to process and store information. Semiconductors and magnetic materials have made up the bulk of data storage devices for decades. In recent years, however, researchers and engineers have turned to ferroelectric materials, a type of crystal that can be manipulated with electricity.
In 2016, the study of ferroelectrics got more interesting with the discovery of polar vortices essentially spiral-shaped groupings of atoms within the structure of the material. Now a team of researchers led by the U.S. Department of Energy s (DOE) Argonne National Laboratory has uncovered new insights into the behavior of these vortices, insights

The unique interactions between perovskite oxide, its changing surface layer, and iron species that are active toward the OER paves a new path for the design of active and stable materials, bringing us one step closer to efficient and affordable green hydrogen production.

Abstract:
A clean energy future propelled by hydrogen fuel depends on figuring out how to reliably and efficiently split water. That s because, even though hydrogen is abundant, it must be derived from another substance that contains it and today, that substance is often methane gas. Scientists are seeking ways to isolate this energy-carrying element without using fossil fuels. That would pave the way for hydrogen-fueled cars, for example, that emit only water and warm air at the tailpipe.

Landmark discovery may lead to safe, effective antiviral drugs against COVID-19
The COVID-19 vaccines currently rolling out are providing hope that the spread of the disease can be halted. But infection rates are still high, and for those who contract COVID-19, the search for effective treatments remains important.
Researchers examining the atomic structure of SARS-CoV-2, the virus that causes COVID-19, have made a landmark discovery that could contribute critical information to the design of safe and effective antiviral drugs in the fight against the virus.
Understanding enzymes goes hand in hand with understanding their atomic structures -; and the higher resolution the better, because subtle differences can affect the interpretation. We wanted the best data possible, so we went to the APS.
