Low temperature plasma treatment of polymeric membranes: a comparative review
Abstract: This paper presents a comparative study of plasma surface modification of various polymeric membranes. Low temperature plasma treatment using pulsed direct current discharge of different gases was employed to enhance hydrophilicity of membranes. Radio frequency discharge of various gases was used to improve surface properties of different polymeric membranes. The enhancement of hydrophilicity of the plasma modified membrane surface was evaluated by measuring the contact angle. The membranes were characterized …

Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …

Review On Bipolar Plate Geometric Design and Materials for Proton Exchange Membrane Fuel Cell Applications
Abstract: Abstract Bipolar plates (BPs) are vital components in proton exchange membrane fuel cells (PEMFCs), performing multiple essential functions that directly influence system efficiency, durability, and overall operational performance. They ensure uniform distribution of reactant gases across the active area, provide electrical conductivity between adjacent cells, assist in effective thermal management by dissipating heat generated during electrochemical reactions, and maintain proper sealing to prevent leakage of gases and coolant. Among these …
