Anion-adsorbing membranes provide an interesting possibility to remove toxic arsenate and chromate from drinking water. A promising way prepare anion-exchange materials is introduce positively charged amine groups on polymers. In this study, polyacrylonitrile (PAN) ultrafiltration were modified with functionalities the membranes. The success of modifications was demonstrated using infrared spec...

We provide a comprehensive review of advanced membrane materials for organic solvent separations exhibiting superior and robust separation properties, including polymeric architectures porous with well-controlled nanostructures.

Oil–in–water emulsion separation is a challenging process in industries due to the large volumes of emulsified oil produced. Membrane technology has become more important treatment its high efficiency and straightforward operational procedure. Up now, microfiltration ultrafiltration are most utilized membrane processes for oil-in-water separation. However, deals with several problems. The prese...

Background and Objectives: One of the problems in juice membrane clarification is the accumulation and deposition of rejected compounds on membrane surfaces or inside its pores which results in a membrane fouling. Materials and Methods: Several parameters can have influence on fouling in one hand and prediction of juice permeates flux during the membrane processing is of importance in indust...

The performance of high-temperature polymer electrolyte membrane fuel cells (HT-PEMFC) is critically dependent on the selection of materials and optimization of individual components. A conventional high-temperature membrane electrode assembly (HT-MEA) primarily consists of a polybenzimidazole (PBI)-type membrane containing phosphoric acid and two gas diffusion electrodes (GDE), the anode and t...

BACKGROUND The purpose of this study was to investigate the clinical characteristics of a hyporeflective space between hyperreflective materials in pigment epithelial detachment (PED) and Bruch's membrane in neovascular age-related macular degeneration (AMD) using spectral-domain optical coherence tomography (SD-OCT) or swept source optical coherence tomography (SS-OCT). METHODS Among 223 pat...
