Extracting clean fuel from sunlight

Securing enough energy to meet human needs is one of the greatest challenges society has ever faced. Previously reliable sources—oil, gas and coal—are degrading air quality, devastating land and ocean and altering the ...

Research breakthrough could transform clean energy technology

By some estimates, the amount of solar energy reaching the surface of the earth in one year is greater than the sum of all the energy we could ever produce using non-renewable resources. The technology necessary to convert ...

3D graphene: Solar cells' new platinum?

One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.

'Artificial leaf' makes fuel from sunlight (w/ video)

Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that ...

Adding a carbon atom transforms 2-D semiconducting material

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers ...
