The photogating effect has been previously utilized to realize ultra-high photoresponsivity in a semiconductor-graphene hybrid photodetector. However, the spectral response of the graphene hybrid ...

Chemists Joel Rosenthal and Daniel G. Nocera of the Massachusetts Institute of Technology provide this answer. When molecular hydrogen (H 2) and oxygen (O 2) are combined and allowed to react together ...

The spontaneity of redox reactions is demonstrated using copper, zinc, and silver, and their cations. When solid zinc is placed in Cu2+ solution, the blue color of the solution becomes less intense as ...
