In Physics of Fluids, researchers show a droplet remains liquid for a much shorter time on a porous surface, making it less favorable to survival of the virus. Left: Schematic of capillary imbibition ...

Although advances in refrigeration technology means we don’t need to defrost the freezer as often as we used to, many of us are still forced to carry out the task on a regular basis lest we find the ...

Dr. Seunghak Lee, Jaeshik Chung, and Sang Hyun Kim of the Water Resources Cycle Research Center at the Korea Institute of Science and Technology (KIST) observed how oil and water interact in porous ...

Porous land such as foliage significantly lowers noise made by drones and air taxis which could reduce disturbances for urban communities as Urban Air Mobility (UAM) grows. The findings, published ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...
