2001 journal article

Optimization of scanning transmission X-ray microscopy for the identification and quantitation of reinforcing particles in polyurethanes

ULTRAMICROSCOPY, 88(1), 33–49.

By: A. Hitchcock *, I. Koprinarov*, T. Tyliszczak*, E. Rightor*, G. Mitchell*, M. Dineen*, F. Hayes*, W. Lidy* ...

author keywords: X-ray microscopy; polymers; quantitative chemical mapping; particle size distributions
MeSH headings : Microscopy, Electron, Scanning / instrumentation; Microscopy, Electron, Scanning / methods; Particle Size; Polyurethanes / chemistry; X-Rays
TL;DR: The size distribution of all particles determined by STXM is shown to be similar to that determined by TEM, and the size distributions of each type of reinforcing particle, which differ considerably, were obtained by analysis of STXM images at chemically selective energies.
