Journal Article
Rigby, S. P., Husan, M., Hitchcock, I., & Fletcher, R. S. (2017). Detection of the delayed condensation effect and determination of its impact on the accuracy of gas adsorption pore size distributions. Colloids and Surfaces A: Physicochemical and Engineering Aspects, 517, https://doi.org/10.1016/j.colsurfa.2016.12.043

Macroscopic, highly disordered, mesoporous materials present a continuing challenge for accurate pore structure characterization. The typical macroscopic variation in local average pore space descriptors means that methods capable of delivering stati...
