Research has shown that vulnerable communities are facing the dangers of complex environments.
Serious danger accumulation in a very social vulnerable census. Credit: Environmental survey letter (2024). Doi: 10.1088/1748-9326/AD9EC7 Environmental disasters have confused the life of the entire region and are on the same burden of communities that are already facing social and economic difficulties. Extreme events, such as floods caused by Tennessee and Hurricane Helen in North Carolina, indicate this phenomenon in…

New “all-optical” nanoscale force sensor accesses previously inaccessible environments
Illustration of atomic arrangement within a single lanthanide-doped nanocrystal. Each lanthanide ion can emit light. Credit: Andrew Mueller/Columbia Engineering Mechanical forces are an essential feature of many physical and biological processes. Telemetry of mechanical signals with high sensitivity and spatial resolution is required for a wide range of applications, from robotics to cell biophysics and medicine, and even space travel.…

Neural networks unlock the potential of high-entropy carbonitrides in extreme environments
The crystal structures of high-entropy carbide and carbonitride (TiZrTaHfNb)C0.75N0.25 were simulated at 3000, 3500, 4000, and 4500 K (liquid), respectively. The inset shows the nonmetallic sublattice. Carbon atoms are shown in gray and nitrogen in red. Credit: Alexander Kvashnin et al. Melting point is one of the most important measurements of material properties and informs the potential applications of materials…

Flexible thermoelectric fibers for wearables maintain stable energy performance even in extreme environments
Schematic diagram and actual images of an all-inorganic flexible thermoelectric yarn made without the use of polymer additives. Credit: KAIST A team of South Korean researchers has developed a thermoelectric material that can be used in wearable devices such as smart clothing and maintains stable thermal energy performance even in extreme environments. This dramatically solved the long-standing problem in the…
