Water pumping effect over the organic ions defined graphene oxide membrane impulses high flux desalination

Dian Gong et al.

Summary: In this study, graphene oxide (GO) membranes were modified by confining organic ions to achieve high water flux and ion rejection. The organic ions not only control the channel size, but also shorten the vapor diffusion distance and increase water permeability.

Recent Progress in a Membrane-Based Technique for Propylene/Propane Separation

Meng Guo et al.

Summary: The similar physico-chemical properties of propylene and propane molecules make their separation challenging. Membrane separation techniques offer significant prospects in propylene/propane separation due to their low energy consumption and investment costs. Organosilica membranes have attracted attention for their good molecular sieving properties and high hydrothermal stability.
