Surface sieving carbon skins for propylene and propane separation
The adsorptive separation of olefin/paraffin mixtures requires the development of robust adsorbents with high selectivity and adsorption capacity. Here we introduce surface sieving carbon adsorbents for propyl...

Molecular transport under extreme confinement
Mass transport through the nanoporous medium is ubiquitous in nature and industry. Unlike the macroscale transport phenomena which have been well understood by the theory of continuum mechanics, the relevant p...
