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 ...

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, ...

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 ...

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 ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.
