Recent advances in hard disk drive mechanics, specifically the successful introduction of helium-filled enclosures, have enabled significant increases in drive capacity. The track mis-registration ...

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

An efficient NMR approach is described for determining the chemical structures of the monosaccharide glucose and four disaccharides, namely, nigerose, gentiobiose, leucrose and isomaltulose. This ...
