Membrane Separation and Gas Transport

Membrane Separation and Gas Transport is a research topic within Mechanical Engineering. Science Explorer counts 24k research works in it since 1950. 31.5% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the advances in membrane gas separation technology, including the development of mixed matrix membranes, polymeric membranes, and metal-organic frameworks for improved gas permeability and selective CO2 capture. It also explores the application of pervaporation and polymer of intrinsic microporosity (PIMs) in enhancing gas separation performance and hydrogen purification.
