Thus, a laser - based technology for reduction of graphene oxide, conversion of the solution based
metal oxide precursor and patterning of graphene electrodes and metal oxide semiconductor was developed.
All of Bullfrog Power's electricity comes from wind and low - impact hydro facilities that do not emit any carbon dioxide, nitrogen
oxides and sulphur dioxide (
precursors to smog), particulate matter (which gives rise to respiratory disease), heavy
metals (mercury, lead, cadmium) and carcinogens.
