Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic magnetic orientations of electrons) and atoms start forming new arrangements, promoting new phases of matter or stretching a crystal lattice. /news/2025-11-solid-oxygen-crystal-extreme-magnetic.html General 糖心视频ics Condensed Matter Sat, 08 Nov 2025 07:30:02 EST news681643943 When a slab slides beneath an overriding plate in a subduction zone, the slab takes on a property called anisotropy, meaning its strength is not the same in all directions. Anisotropy is what causes a wooden board to break more easily along the grain than in other directions. In rock, the alignment of minerals such as clay, serpentine, and olivine can lead to anisotropy. Pockets of water in rock can also cause and enhance anisotropy, as repeated dehydration and rehydration commonly occur at depth in a subducting slab. /news/2025-10-earthquake-grain.html Earth Sciences Mon, 27 Oct 2025 14:36:03 EDT news680794562 A research team led by Professor Jong Sung Yu of the Department of Energy Science and Engineering at DGIST has developed a new alloy structure that can significantly enhance the performance of electrode catalysts, a key component of hydrogen fuel cells. /news/2025-10-magnetic-interactions-alloy-catalyst-hydrogen.html Analytical Chemistry Materials Science Tue, 21 Oct 2025 08:12:03 EDT news680253121 Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.
