How to get rid of the coffee-stain effect

3 июля, 2020 - 12:24
Previously, researchers discovered that the well-known coffee-stain effect is caused by a remarkable mechanism, showing avalanche-like behavior of particles in a fluid. They now show how to prevent the ring-shaped coffee-stain and get a uniform distribution of the particles instead.

The superiority of single-layer molybdenum disulfide for water desalination

3 июля, 2020 - 09:25
Researchers show that a nanoporous MoS2 membrane allows a higher water flux compared with other 2D materials such as graphene, boron nitride and phosphorene. The team dug deeply into the physical reasons behind why MoS2 performed better than other two-dimensional materials in water desalination processes. Through molecular dynamics simulation, they found out that water density near a MoS2 membrane is lower compared to that near other materials, which indicates that water molecules were more likely to transport through the membrane instead of accumulating around it.
