Ferromagnetic semiconductors, which combine semiconductor and magnetic properties, are key to developing spin-based devices. Previously studied materials, such as (Ga,Mn)As, have Curie temperatures below room temperature, thereby limiting their practical use. Now, researchers from Institute of Science Tokyo and The University of Tokyo have overcome these limitations by utilizing the step-flow growth method, achieving a record-high Curie temperature of 530 K, facilitating the development of stable, room-temperature semiconductor spintronic devices.

Hydrogen boride (HB) nanosheets can inactivate viruses, bacteria, and fungi within minutes in the dark conditions. By coating surfaces with HB nanosheets, it rapidly inactivates SARS-CoV-2, influenza virus, and other pathogens. The nanosheets work by denaturing microbial proteins, offering a safe, effective, and versatile antimicrobial coating for everyday items.

Examining complex heat transfer processes in detail, even under extreme conditions such as those found in power plants and industrial plants – this is now possible with the COSMOS-H research facility at Karlsruhe Institute of Technology (KIT) which was opened on Thursday, May 8, 2025. For the first time, scientists have an infrastructure at their disposal to investigate flow and boiling phenomena in detail, even under realistic high-pressure conditions.
