Researchers have reported the high-performance SnS thermoelectric crystals combining the desirable features of low-cost, earth-abundant materials and environmental friendliness. For the first time, they discovered the interplay of triple electronic bands leading to the high performance of thermoelectric SnS crystals, which is promoted by Se alloying. Furthermore, Se alloying plays a second important role in lowering the thermal transport.
Read moreUS cities could see a decline in mortality rates and an improved economy through midcentury if federal and local governments maintain stringent air pollution policies and diminish concentrations of diesel freight truck exhaust, according to new research.
Read moreTo develop higher capacity batteries, researchers have looked to lithium sulfur batteries because of sulfur's high theoretical capacity and energy density. But there are still several problems to solve before they can be put into practical applications. The biggest is the shuttling effect that occurs during cycling. To solve this problem and improve lithium sulfur battery performance, the researchers created a sandwich-structured electrode using a novel material that traps polysulfides and increases the reaction kinetics.
Read moreResearchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11.
Read moreResearchers have reported a nanocatalyst that is able to produce hydrogen isotope compounds D2 and HD via the heterogeneous dehydrogenation of formic acid in the presence of heavy water. Amine groups on the catalyst support provided a handle for tuning the selectivity of the reaction through their basicity. It is hoped that the reported process, which is appropriate for large-scale production, can be used to improve the accessibility of deuterated materials worldwide.
Read moreWhen designed holistically, tidal barrage schemes can provide additional transport links for commuters, become tourism destinations, mitigate wildlife habitat loss, as well as provide opportunities to boost people's health and wellbeing with additional options for cycling and walking, say researchers.
Read moreResearchers have come up with a new, safe way to clean up oil spills using compounds equally useful as common household cleaning products.
Read moreSeparating pure ethylene from ethane is a difficult and costly process, but one that new research is poised to streamline. The technique would avoid liquefaction and distillation by designing a material that only binds ethylene molecules, thus separating them from ethane.
Read moreThere is no clear link between cancer incidence and locally produced food from an area with a history of glass manufacture with contaminated soil, according to a new study. A high consumption of certain local foods seems to be linked to an increased risk of certain cancers, but this probably reflects that the exposure to contaminants was higher in the past.
