Knowledge of the structure of biological macromolecules, especially in their native environment, is crucial because of the close structure–function relationship. X-ray small-angle scattering is used ...

Polyurethane elastomers (PUEs) were prepared with poly(oxytetramethylene) glycol (M n =2000), 4,4′-diphenylmethane diisocyanate, 1,4-butanediol (BD) and 1,1,1 ...

The author describes the development of small-angle X-ray scattering and analyzes its advantages in the characterization of drug-delivery systems and large molecules. This article is part of a special ...
