When adhesion is stronger than cohesion, capillary action occurs. The rate of capillary flow is still affected by the viscosity of a fluid and the geometry and surface energy of the surfaces of the ...

Researchers are still busy trying to understand some of the CNT basics, for instance something as fundamental as "how do nanotubes grow"? How can their various properties – electronic, transport, or ...

ANN ARBOR, Mich.---Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes ...

Coating the inside of glass microtubes with a polymer hydrogel material dramatically alters the way capillary forces draw water into the tiny structures, researchers have found. The discovery could ...

Capillary electrophoresis (CE) is a fast-growing area of separation technology. CE techniques enable the high-resolution separation of an impressive variety of sample types, from ions and small ...

When you water plants, you water their roots. But how does the water travel all the way from the roots of the plant to the leaves? They are standing upright: wouldn’t that defy gravity? In fact, there ...

Controlling light in optical systems quickly and easily is crucial for all-optical switching. An approach that does this by exploiting the condensation of gases in a porous structure could open up new ...
