“BiSb expands the potential of topological insulators for ultra-low-power electronic devices Scientists have developed the world’s best-performing pure spin current source1 made of bismuth–antimony (BiSb) alloys, which they report as the best candidate for the first industrial application …
News Barium ruthenate: A high-yield, easy-to-handle perovskite catalyst for the oxidation of sulfides
“Researchers at Tokyo Tech have developed a ruthenium-based perovskite catalyst1 that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The …
“A Tokyo Institute of Technology research team has shown copper nitride acts as an n-type semiconductor, with p-type conduction provided by fluorine doping, utilizing a unique nitriding technique applicable for mass production and a computational search for appropriate doping elements …
“Researchers at Tokyo Tech have developed flexible terahertz imagers based on chemically “tunable” carbon nanotube materials. The findings expand the scope of terahertz applications to include wrap-around, wearable technologies as well as large-area photonic devices. Carbon nanotubes (CNTs) are beginning …
“Ultrashort Light-pulse-induced vibrations of atoms in a lattice, called optical coherent phonons, have been controlled in various materials. However, different experiments demonstrating such control have been explained differently through empirical theories, and a unified theory based on quantum mechanics is …
