A team of 15 female materials scientists and engineers from Pacific Northwest National Laboratory has collectively provided their perspective on identifying and speeding up the slowest steps when studying and designing the battery's electrochemical p.....»»
How to Get Android 13 Developer Preview 1 on Your Google Pixel Phone
We’ve warned you in a couple of separate posts that downloading and installing the Android 13 Developer Preview 1 on your Pixel phone is probably not a good idea right now, unless you are a developer. Google made it crystal clear in their annou.....»»
Researchers develop promising molecule in quest to create drug to treat COVID-19
Uppsala researchers have succeeded in designing a molecule that inhibits the replication of coronaviruses and has great potential for development into a drug suitable for treating COVID-19. The molecule is effective against both the new variant and p.....»»
Predicting superconductor crystal structures with computer simulations
Superconductivity refers to the loss of electrical resistance of a material and requires extremely low temperatures (< -200 degrees Celsius) in order to persist. This low temperature, otherwise known as the transition temperature, has been a limiting.....»»
Scientists discover a mysterious transition in an electronic crystal
When temperature changes, many materials undergo a phase transition, such as liquid water to ice, or a metal to a superconductor. Sometimes, a so-called hysteresis loop accompanies such a phase change, so that the transition temperatures are differen.....»»
Taiwan 2021 photonic production value up 16.7% on year, says PIDA
Taiwan-based optoelectronics makers generated a total production value of NT$1,671.7 billion (US$60.1 billion) in 2021, increasing 16.7% on year, according to the government-sponsored Photonics Industry & Technology Development Association (PIDA)......»»
Hydrogen-soaked crystal lets neural networks expand to match a problem
Programmable control of hydrogen atoms allows switching between useful states. Enlarge (credit: Getty Images) Training AIs remains very processor-intensive, in part because traditional processing architectures are poor matches.....»»
N-alkanes proved to be a safe, novel and green cooling material
The traditional refrigerant Freon is a strong greenhouse gas that leads to serious climate problems. Stimulated by the excellent cooling performance of plastic crystal materials, barocaloric (BC) cooling received much attention recently as a promisin.....»»

NASA is working on a new design of supersonic plane which, instead of causing a sonic boom, causes a quieter sonic thump......»»
Study reveals topology at the corner of the dining table
A joint research team from the Hong Kong University of Science and Technology (HKUST) and the University of Tokyo discovered an unusual topological aspect of sodium chloride, commonly known as table salt, which will not only facilitate the understand.....»»
Nano-architected material refracts light backward; an important step toward creating photonic circuits
A newly created nano-architected material exhibits a property that previously was just theoretically possible: it can refract light backward, regardless of the angle at which the light strikes the material......»»
Ion pairings change honeycomb crystal states
Tohoku University researchers have observed a rare change in the structure of a mineral-like crystal that, if controlled, could lead to the development of new functional materials. The findings were reported in the Journal of the American Chemical So.....»»
Solving a crystal"s structure when you"ve only got powder
Crystals reveal the hidden geometry of molecules to the naked eye. Scientists use crystals to figure out the atomic structure of new materials, but many can't be grown large enough. Now, a team of researchers report a new technique in the January 19.....»»
A nonlinear-transport perspective of field-induced phase transitions in pentatellurides
Combining topological states of matter with strong electron correlation promises many exotic phenomena such as charge fractionalization, excitonic instability, and axionic excitation. Layered transition-metal pentatellurides ZrTe5 and HfTe5 were foun.....»»
Research produces record levels of strain in single-crystal silicon
University of Surrey researchers have developed a single-step procedure to put single-crystal silicon under more strain than has been achieved before. The discovery, which has a patent pending, could be crucial to the future development of silicon ph.....»»
