Researchers develop new method to remove dust on solar panels

Taking a cue from the self-cleaning properties of the lotus leaf, researchers at Ben-Gurion University of the Negev have shed new light on microscopic forces and mechanisms that can be optimized to remove dust from solar ...

'Self-cleaning' concrete could keep buildings looking new

Building materials that clean themselves could save immense time and labor in homes and businesses, as well as reduce disease risk in settings such as hospitals. Now, researchers reporting in ACS Applied Materials & Interfaces ...

Solving a condensation mystery

Condensation might ruin a wood coffee table or fog up glasses when entering a warm building on a winter day, but it's not all inconveniences; the condensation and evaporation cycle has important applications.

Researchers solve mystery of how gas bubbles form in liquid

The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those ...

Using waves to move droplets

Controlling individual droplets leads to more efficient self-cleaning surfaces and lab-on-a-chip implementations. University of Groningen professor Patrick Onck and colleagues from Eindhoven University of Technology have ...

Jumping drops get boost from gravity

A decade ago a new idea was brought into the general scientific community—shedding water from condensers was more efficient by using surface tension to make microscopic water droplets "jump" off the surface. The idea took ...
