(Nanowerk News) For more than 100 years, scientists have been using X-ray crystallography to determine the structure of crystalline materials such as metals, rocks, and ceramics. This technique works ...

Every crystal's shape is a mirror of the internal arrangement of its molecules, but the molecules in photoswitchable crystals ...

For materials that exist only as a powdered crystal, solving these structures becomes much more difficult because the fragments don't carry the full 3D structure of the original crystal. "The precise ...
