Effect of Polymer Concentr ation on the Structure and Performance of Polysulf one Flat Membrane for CO 2 Absorption in Membrane Contactor

Structure Formation in Anode and Its Effect on the Performance of Micro-Tubular SOFC: A Brief Review

Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to ...

A Comparative Study on the Application of Porous PES and PEI Hollow Fiber Membranes in Gas Humidifcation Process

Humidification process is one of the applications of membrane contactor in which partial pressure of a vapor in the gas stream increases. In this study, two different polyethersulfone and polyetherimide hollow fiber membranes were fabricated and characterized by various test methods and their performance in humidification process under different operating conditions was investigated. The PES me...

Efficient Immobilised TiO2 in Polyvinylidene fluoride (PVDF) Membrane for Photocatalytic Degradation of Methylene Blue

Immobilised titanium dioxide (TiO2) in membrane structures has recently become attractive. This is due to the elimination of the separation step after the process of photocatalytic degradation. The efficiency of the TiO2 surface area exposed to UV light as the main important parameter needs to be considered. The immobilisation of TiO2 nanoparticles in the polyvinylidene fluoride (PVDF) membrane...

Computer Aided Molecular Modeling Of Membrane Metalloprotease

Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

Effect of Ultrasonication on Membrane Structure and Flux Recovery for Whey Ultrafiltration

In this study, the effect of ultrasound irradiation on the flux recovery and fouling mitigation for the membranes made of the polysulfone by the phase inversion method were investigated. Two ultrasound irradiation regimes, including inside and outside the module, were chosen for this study. The experiments were conducted to investigate the effect of ultrasound irradiation on the membrane struct...
