Are we at the limits of measuring water-repellent surfaces?

How liquids are repelled by a surface, a property called "wettability," is important for engineers to develop aircraft that resist ice formation, for fashion designers developing outdoor gear that repels rain and dirt, and ...

Surface science concepts are up for revision

The textbook directions for characterizing the wetting properties of solid surfaces are likely to change as KAUST researchers demonstrate that conventional tests can be misleading.

Filter may be a match for fracking water

A new filter produced by Rice University scientists has proven able to remove more than 90 percent of hydrocarbons, bacteria and particulates from contaminated water produced by hydraulic fracturing (fracking) operations ...

Gas gives laser-induced graphene super properties

Rice University scientists who invented laser-induced graphene (LIG) for applications like supercapacitors have now figured out a way to make the spongy graphene either superhydrophobic or superhydrophilic.

Added bacterial film makes new mortar resistant to water uptake

Moisture can destroy mortar over time - for example when cracks form as a result of frost. A team of scientists at the Technical University of Munich (TUM) has found an unusual way to protect mortar from moisture: When the ...

Flow phenomena on solid surfaces

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between ...
