Item New inorganic membranes for gas separations which are stated above the Robeson’s trade-off upper bound(Elsevier, 2023) Pallavi, K.C.; Isloor, A.M.; Mohammad, A.W.Gas isolation and separation methods are very precious among the operations in the industry related to oil and gas. Conventional methods involve huge extent of energy and less performance. Inorganic membranes possess excellent chemical, thermal, and mechanical stability compared to any other conventional counterparts. Very fast and attractive progresses have been found regarding inorganic membrane material modeling and development, fabrication method, control over microstructure, and optimization. Various zeolite, silica, and carbon-derived membranes are found effective in gas separations such as natural gas isolation, helium extraction, carbon dioxide capture, hydrocarbon separations, and many more. Because of the good stability, high separation performance, nonvolatility, and designable properties of the inorganic membranes, they have been rendered as novel potential candidates and alternative media for gas separation. This content enables to find out the new developments happened in the domain of inorganic membranes utilized in gas separation which stay above the Robeson’s boundary. © 2024 Elsevier Inc.

It can start malfunctioning due to various health conditions, in which case the process of extracorporeal blood purification - the haemodialysis - comes into focus. An efficient membrane is the heart of any dialysis technique. Selection of a proper dialysis membrane relies mainly on the material biocompatibility, toxin rejection, and antifouling profile. Many bio-derived polymers such as chitosan, cellulose acetate, and polylactic acid have been found to be attractive in terms of outstanding cytocompatibility. The existing low-range mechanical robustness of bio-derived polymeric substrates can be facilitated by the immobilization of membrane through use of nanoparticles. Polyetherimide, polyether sulfone, poly(vinylidene fluoride), and polysulfone which belong to the synthetic polymers are also utilized as dialysis membrane materials. Modifiers or nanostructured particles such as bioactive glass, anticoagulant-natured heparin, some copolymers, graphene oxide, and many more are incorporated into a membrane for its integration in terms of cytocompatibility, hydrophilicity, selective rejection, good permeation. and antifouling characteristics. The membrane-blood compatibility is assessed with respect to the lowered adhesion of platelets and proteins, long durable plasma recalcification time, reduced thrombus formation, and haemolysis proportion. A wide variety of polymer recipes have been developed for the fabrication of haemodialysis membranes. This chapter traces the various distinctive attempts made by researchers that have been appreciable in developing a potent haemodialysis membrane set-up. © 2024 selection and editorial matter, Anil Kumar Pabby; S.
