Structures determined from powder diffraction data by trial and error method

Some structures determined early in China
from powder diffraction data by trial and error method

Institute of physics, Chinese Academy of Sciences

Powder diffraction concepts were soon introduced in China because of a few chinese students trained in England by the two Braggs - son and father - inventors of crystal structure analysis.

The following papers were kindly provided by Xiaolong Chen (Institute of Physics, Academy of Sciences, Beijing).
