(PhysOrg.com) -- By itself, titanium dioxide (TiO2) is a very poor electrode. Electrons move very slowly through the material - so slowly, in fact, that it can take years to fill a millimeter-thick piece of TiO2. However, ...
(PhysOrg.com) -- Porphyrins are most commonly thought of as the pigment in red blood cells, but now scientists have found that porphyrins can also be used to increase the efficiency of an inexpensive type of solar cell. In ...
A team of University of California, Riverside's Bourns College of Engineering students created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen ...
