For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...

IN opening the discussion on electron diffraction and surface structure before a joint meeting of the Physical and Chemical Societies held on March 17, Prof. G. I. Finch compared electron diffraction ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Researchers have used artificial intelligence to predict dozens of previously unknown carbon crystal structures, including at ...

I know, this is being picky, but the double helix structure of DNA was not proposed based on a crystal structure. DNA oligonucleotides suitable for crystallization were not available to Wilkins and ...

When looking at calcite under a microscope, a scientist would immediately recognize the crystalline form of calcium carbonate by its rhombohedral appearance. That is, calcite is shaped like a ...
