The authors present a simple and material-sparing approach for estimating the powder-flow performance of previously uncharacterized single-component bulk powders when only particle-size distribution data are available.

X-ray microtomography has great potential for improving the understanding of the structural features of solid dosage forms and the changes in those features during manufacturing, handling, and storage. This article describes the basic principles of the technique and provides examples of its potential applications.
