Olive-shaped SnO2 nanocrystals were synthesized successfully via a facile hydrothermal route, using tin dichloride hydrate, oxalic acid dihydrate and polyvinylpyrrolidone as reaction precursors, and showed great potential in the large-scale preparation of SnO2 nanocrystals. The prepared SnO2 nanocrystals were characterized

Lefetamine (N,N-dimethyl-1,2-diphenylethylamine, L-SPA) was marketed as an opioid analgesic in Japan and Italy. After being widely abused, it became a controlled substance. It seems to be a pharmaceutical lead for designer drugs because N-ethyl-1,2-diphenylethylamine (NEDPA) and N-iso-propyl-1,2-diphenylethylamine (NPDPA) were confiscated
