Item Review on polymeric membrane materials for gas separations which are stated above the Robeson’s trade-off upper bound(Elsevier, 2023) Vijesh, A.M.; Isloor, A.M.Membrane separation of gases is highly energy efficient and are widely accepted compared to other conventional gas separation methods. Membrane gas separation plays a vital role in the protection of our environment and ensures sustainable growth of industries. The compromise between permeability and selectivity as explained by the Robeson’s upper bound minimized the number of commercial gas separation membranes. It unveiled the tailoring of new materials in the design of superior membranes. This review chapter explores the recent developments of membrane materials for various gas/vapor separation applications. © 2024 Elsevier Inc. All rights reserved.Item Membrane technology—a promising approach for metal ion extraction(Elsevier, 2024) Antony, N.; Vijesh, A.M.; Isloor, A.M.Metal ion extraction using ion exchange membranes (IEM) receives much attention as it can find a solution to environmental problems to reduce emissions of heavy metals from wastewater contaminated with industrial effluents. Among the various IEM available, cation exchange membranes are widely used by researchers due to its enhanced ability to hold the metal ion and retain them in the organic phase. This review book chapter emphasizes the extraction of metal ions, specifically about the studies carried out in the field of iron, zinc, and copper metal ions using IEM. © 2024 Elsevier Inc.

Hydrogen-based fuel cells, supercapacitors, and batteries are used as energy storage devices in many commercial applications to make them a cleaner and more environmentally friendly process. Hydrogen produced from nonrenewable energy sources, such as oil, natural gas, and coal, is not cost-effective and involves processes that pollute our environment. Thus, developing economically viable and environmentally friendly processes is necessary to satisfy the massive demand for H2 as a green energy source. This chapter provides a comprehensive review of pilot-scale studies conducted in the field of membrane-based biohydrogen technology. © 2026 Elsevier Inc. All rights reserved.
