Scientists have developed a software package called GENESIS (GENeralized Ensemble SImulation System) which is designed to perform molecular dynamics (MD) simulations for studying large biological systems containing 10 or even 100 million atoms.
Researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing. They also developed a radio-controlled trigger that could remotely activate self-destruction on demand.
Twin boundaries - which are small, symmetrical defects in materials - may present an opportunity to improve lithium-ion batteries. The twin boundary defects act as energy highways and could help get better performance out of the batteries.
Researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework (MOF), a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting.
Researchers demonstrated that by irradiating a thermoelectric semiconductor with high-energy alpha particles, they can control native defects in the crystal so that these defects actually enhance the performance of the thermoelectric material by a factor of up to ten.
Scientists have developed a generalized strategy for the synthesis of mesoporous colloidal superparticles made of nanocrystals of platinum-group metals through self-limited growth of metal nanocrystals (or precursors) and silver halide in individual colloidal particles.
Rersearchers have created unexpected shapes of mesoscale atoms - structures built of microdroplets encapsulated within microdroplets. The discovery was possible with a new method for precise control over placement of tiny segments of liquid, one in another. With further progress in innovative microfluidic systems, the method may find use in medicine and materials science.
Most people are naturally adept at reading facial expressions - from smiling and frowning to brow-furrowing and eye-rolling - to tell what others are feeling. Now scientists have developed ultra-sensitive, wearable sensors that can do the same thing.
