Transforming Gas Separations with Scalable Carbon Molecular Sieve Membranes Enabled by Chemically Tuned Hollow‐Fiber Precursors

ABSTRACT Blending hydrogen into natural gas pipelines requires efficient separation, while helium recovery from natural gas via cryogenic distillation is energy‐ and capital‐intensive, driving demand for better membranes. This study develops ultraselective carbon molecular sieve...

Direct Air CO2 Capture via Hot Water Cycling of Poly(ethyleneimine)/Silica Hollow Fiber Sorbents

Abstract Hollow fiber sorbents containing amine-infused mesoporous silicas are promising materials for CO2 capture from ambient air due to their ease of heat integration and low pressure drops. This advanced sorbent design permits a wide range of heat source integration options,...
