Crystallography and Chemistry: An Ongoing Engagement
A number of women were pioneers in X-ray crystallography at a time when they were excluded from most other branches of physical science. Kathleen Lonsdale was a research student of William Henry Bragg, who with his son Lawrence founded the science of X-ray crystallography at the beginning of the 20th century. She is known for both her experimental and theoretical work… WebApr 22, 2024 · Crystallization Definition. Crystallization is a natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or gas. This can be caused by a physical change, such as a temperature change, or a chemical change such as acidity.
