Ceramic membranes are considered as alternatives for their polymeric counterparts due to highmechanical strength and thermal resistance; thus long lifetime. Usually, asymmetric ceramicmembranes are synthesized including several layers with different pore size distributionswith the top-layer playing the main separation role. Titania has several properties such asphotocatalytic activity and chemi...

the overall goal of this study was to identify the appropriate biomaterials able to facilitate the regeneration in rat's injured adult spinal cord. acute damage to axons is manifested as a breach in their membranes, ionexchange distortion across the compromised region, local depolarization and even conduction block. it would be of particular importance to interrupt the progress of events h...

uv-induced grafting technique was used as a flexible method for surface modification of polysulfone (psf) ultrafiltration (uf) membranes in order to prepare hydrophilic nanofiltration (nf) membranes. flat sheet polysulfone (psf) ultrafiltration membranes were prepared via phase inversion method. n-methylene-2-pyrrolidone (nmp) and polyethylene glycol (peg) of three different molecular weights (...

Polymeric filtration membranes could be a cost-effective alternative to cation exchange (CEMs) in electrolysis with contained anolyte and saltwater catholyte because they size selectively hinder salt ion transport between compartments while facilitating proton hydroxide transport. Optimizing membrane performance requires better understanding of properties that impact electrical resistances rete...

objective(s): nowadays hydrogels are one of the upcoming classes of polymer-based controlled-release drug delivery systems. temperature and ph-responsive delivery systems have drawn much attention because some diseases reveal themselves by a change in temperature and/or ph. the objective of this work is to prepare and characterize composite membrane using responsive nanoparticles into a polymer...

In this work, we report the synthesis and characteristics of cyclomatrix polyphosphazene membranes based on interfacial polymerization between 1,1-tris(4-hydroxyphenyl)ethane hexachlorocyclotriphosphazene top alumina or polyacrylonitrile supports. The potential alumina-supported thin film composite as organic solvent nanofiltration has been confirmed with a polystyrene-based molecular weight cu...

Herein, novel bioactive glass flakes (BGFs) (45S5 composition), obtained by compression in the liquid phase a stirred media mill, are combined with chitosan (CS) to develop composite membranes using solvent casting for guided bone regeneration (GBR). The incorporation of BGFs endows CS superior bioactivity as evidenced rapid hydroxyapatite formation after 3 days immersion simulated body fluid (...

The objective of this research was to evaluate a select number of promising surface treatments for making ceramic membranes hydrophobic and suitable for application in direct contact membrane distillation (DCMD). Alumina anodiscTM membranes were made hydrophobic through surface treatments that utilized perfluorodecyltriethoxysilane, trimethylchlorosilane, or trichloromethylsilane. The effective...

Over the past decade or so, alternative energy plays a pivotal role in addressing challenges posed by nature. Polymer electrolyte membrane fuel cell is one of the promising alternative energy and there has been significant research and technological investments done in this field. The key information and future prospective of the field is energy conversion and storage, both of which are essenti...
