A Gemini basic ionic liquid and functionalized cellulose nanocrystal-based mixed matrix membrane for CO/N separation.

Owing to the adverse environmental impact, carbon capture and separation have gained tremendous interest throughout the globe. Herein, a CO/N gas separative mixed matrix membrane containing amine functionalized cellulose nanocrystals and a Gemini basic ionic liquid has been developed, which exhibits the highest permeance of 21 033 GPU and moderate selectivity of 21.3.

Cellulose nanofiber-poly(ethylene terephthalate) nanocomposite membrane from waste materials for treatment of petroleum industry wastewater.

Petroleum industry wastewater contains high level of crude oil and other types of organic substances that can cause immense harm to the agriculture, aquatic as well as terrestrial organisms. Organic solvent resistance of membranes is very important to treat such wastewater that contains high level of organic pollutants. This work reports the designing of a superhydrophilic and organic solvent resistant nanocomposite membrane using waste bottles made of poly(ethylene terephthalate) (PET) and cellulosic papers.
