Chinese scientists have recently developed a facile photochemical route for the preparation of gold nanoparticles with excellent luminescence properties. Gold nanoparticles (AuNPs) are noble metal ...
IT has been a matter of general experience that photochemical reactions are not much altered in their courses by change of light intensity. The range of light intensity hitherto available ...
This is a photochemical product that forms in the atmosphere when water vapour encounters sunlight. "For us, that's perfect. Antarctica works like an on-off switch with the long 'polar nights' in ...
