Researchers reveal electronic nematicity without charge density waves in titanium-based kagome metal
Electronic nematic order in kagome materials has thus far been entangled with charge density waves. Now it is finally observed as a stand-alone phase in a titanium-based Kagome metal, a team of researchers led by Boston College physicists reported re.....»»
Researchers find Asian Americans to have significantly higher exposure to "toxic forever" chemicals
Asian Americans have significantly higher exposure than other ethnic or racial groups to PFAS, a family of thousands of synthetic chemicals also known as "toxic forever" chemicals, Mount Sinai-led researchers report......»»
When proteins get stuck at the solid phase: Unlocking the secrets to brain diseases
Many diseases affecting the brain and nervous system are linked to the formation of protein aggregates, or solid condensates, in cells from their liquid form condensate, but little is known about this process......»»
IBM team builds low-power analog AI processor
Huge arrays of phase-change material perform in-memory processing. Enlarge (credit: IBM) Large language models, the AI tech behind things like Chat GPT, are just what their name implies: big. They often have billions of.....»»
Team develops way to integrate electro-optic modulator device on end faces of a single-mode optical fiber jumper
Electro-optic modulators (EOMs) are cardinal elements in the optical communication networks that control the amplitude, phase and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance EOMs, most in.....»»
I try synthetic salmon and enter the “uncanny valley” of taste
Synthetic fish isn't quite there yet—and may not be worth the effort. Enlarge / It may look a lot like fish, but it's not. (credit: New School Foods) I could count on one thing as I sat down for a multiple-course meal.....»»
Saturday Citations: Ancient anarchists, filthy tycoons and a new state of matter
This week on Phys.org, we published news about ancient anarchists, a hidden phase transition, dark matter developments, hot oceans and pollution taxes......»»
Scientists use FAST to discover a new population of "dwarf" pulses
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. Han Jinlin from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) has detected distinct "dwarf pulses" from a bright.....»»
Stabilizing precipitate growth at grain boundaries in alloys
Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure......»»
Electrochemical flow aziridination of terpenes
Due to the inherent physiological properties of nitrogen-containing heterocyclic moieties, the construction of nitrogen-containing compounds has emerged as one of the central issues in contemporary synthetic chemistry over recent decades. Among these.....»»
Researchers take important step toward developing cavity-based X-ray laser technology
Researchers have announced an important step in the development of a next-gen technology for making X-ray free-electron laser pulses brighter and more stable. They used precisely aligned mirrors made of high-quality synthetic diamond to steer X-ray l.....»»
Scientists theorize a hidden phase transition between liquid and a solid
Anything made out of plastic or glass is known as an amorphous material. Unlike many materials that freeze into crystalline solids, the atoms and molecules in amorphous materials never stack together to form crystals when cooled. In fact, although we.....»»
Uncovering the local atomic structure of zeolite using optimum bright-field scanning transmission electron microscopy
Zeolites have unique porous atomic structures and are useful as catalysts, ion exchangers and molecular sieves. It is difficult to directly observe the local atomic structures of the material via electron microscopy due to low electron irradiation re.....»»
