Key Points

This research aims to develop an improved technique for measuring pore radius distribution in powders using advanced imaging and analytical methods.
Utilized scanning electron microscopy (SEM) for high-resolution imaging of powders.
Implemented deep learning techniques for data processing and analysis.
Applied a robust stereological algorithm to quantify pore distributions.
Achieved greater resolution in measuring sub-micron pores compared to conventional X-ray tomography.
Demonstrated enhanced accuracy in pore size characterization within powders.

Implication

A new method measures pore distributions in powders, suggesting improved accuracy over traditional imaging techniques.

Abstract

A new method combines SEM imaging, deep learning, and a robust stereological algorithm to resolve sub-micron pore distributions in powders, outperforming X-ray tomography resolution.
