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 ...

Producing electricity at estuaries using light and osmosis

Most renewable power technologies are weather dependent. Wind farms can only operate when there's a breeze, and solar power plants rely on sunlight. Researchers at EPFL are working on a method to capture an energy source ...

New surface treatment could improve refrigeration efficiency

Unlike water, liquid refrigerants and other fluids that have a low surface tension tend to spread quickly into a sheet when they come into contact with a surface. But for many industrial process it would be better if the ...

Discovering the next generation of catalysts

The use of solar and wind energy must be doubled to meet the world's demand for clean energy over the next 30 years. Catalysts that can ensure the storage of solar and wind energy in fuels and chemicals will therefore play ...

New catalyst turns pollutant into fuel

Rather than allow power plants and industry to toss carbon dioxide into the atmosphere, incoming Rice University assistant professor Haotian Wang has a plan to convert the greenhouse gas into useful products in a green way.
