Abstract Chemical pesticide delivery is a fundamental aspect of agriculture. However, the extensive use of pesticides severely endangers the ecosystem because they accumulate on crops, in soil, as well as in drinking and groundwater. New frontiers in

In this article, we present a facile approach, pyrolysis end-doping (PED), to finely tune pore structures to optimize separation properties of polyimide-derived asymmetric carbon molecular sieve (CMS) hollow fiber membranes. The PED approach creates

This article considers a previously overlooked feature in carbon molecular sieve (CMS) membranes that we term a “hyperskin” present at the outermost region of dense CMS selective layers. Such a feature with much lower permeability, but similar se
