Physicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly every color of light at high speeds and obtain measurements at and far above room-temperature.
Read moreTungsten diselenide emits light with very special properties. Nobody could tell why — but now, scientists have solved the riddle: a combination of atomic defects in the material and microscopic distortion is responsible for the remarkable effect.
Read moreChemists have created a new material that self-assembles into 2D networks in a predictable and reproducible manner. They have successfully synthesized a complex material by design — paving the way for its suite of new properties to be applied in many fields.
Read morePartial unfolding of proteins can be a major challenge in the industry, as it may affect the stability of products. So how does an empty space or cavity in its hydrophobic core destabilize a protein? And would such a cavity, in fact, be empty? These are some of the questions that researchers answer in a new study.
Read moreThe entry probe of the Galileo mission to Jupiter entered the planet's atmosphere in 1995 in fiery fashion, generating enough heat to cause plasma reactions on its surface. The data relayed about the burning of its heat shield differed from the effects predicted in fluid dynamics models, and new work examines what might have caused such a discrepancy. Researchers now report their findings from new fluid radiative dynamics models.
Read moreIn work that combines a deep understanding of the biology of soft-bodied animals such as earthworms with advances in materials and electronic technologies, researchers have developed a robotic device containing a stretchable transistor that allows neurological function.
Read moreWrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assess this method of defense. Rigorous testing reveals that existing blanket technology can protect structures from a short wildfire attack, but for successful deployment against severe fires and in areas of high housing density, technological advancement of blanket materials and deployment methods, as well as multi-structure protection strategies, are needed.
Read moreTopological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report.
Read moreThe nanoscale radiation detector is a hundred times faster than its predecessors, and can function without interruption.
Read moreResearchers have discovered a new technology for refrigeration that is based on twisting and untwisting fibers. They demonstrated twist-based refrigeration using materials as diverse as natural rubber, ordinary fishing line and nickel titanium wire.
