A small beaker of water can look ordinary. Under the right light, it can also become a quiet factory. In a chemistry lab at Chalmers University of Technology in Sweden, researchers have shown that ...

Water has always responded well to sunlight, evaporating faster under the sun than when heated by other energy sources. For years, scientists knew this happened but didn’t fully understand why. Now, a ...

Researchers at Sun Yat-sen University, China, have developed a new water purification film. This “self-floating photocatalytic film” uses low levels of sunlight to purify highly contaminated water and ...

In a press release Researchers at the Laboratory of Nanoscience for Energy Technology (LNET) at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland announced they had developed a device ...

The proposed brackish water desalination system uses photovoltaic electrodialysis to enable direct-drive desalination at high production rates. It already operated for 6 months on real brackish ...

Cornell scientists have discovered a potentially transformative approach to manufacturing one of the world's most widely used chemicals—hydrogen peroxide—using nothing more than sunlight, water and ...

In the future, we could fuel the world with sunlight and water – using sunlight to derive hydrogen fuel from H2O. Currently, most hydrogen that’s used as feedstock and fuel is derived from natural gas ...
