the rapidly increasing interest in functional materials with reversibly switchable physico- chemical properties has led to significant work on the development of stimuli responsive membranes. thermotropic liquid crystals with their exceptional properties have potentials for drug-delivery applications. thermoresponsive liquid-crystal-embedded membranes were investigated for the purpose of develo...

Countercurrent membrane supported reactive extraction (MSRE) was studied for removal of carboxylic acids from aqueous streams with a PTFE capillary membrane. Analysis the mass transfer rates performed to support modeling process. Total coefficients ranging 2.0·10-7 4.0·10-7 m/s were obtained when extracting lactic acid 20 wt% tri-N-octyl amine in 1-decanol thicknesses 260 µm and 80 µm. The limi...

liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

The membrane contactor system is one of the most important technologies to trap CO2 from natural gas. To apply this technology, hollow fibre membranes with a superhydrophobic surface must be used, where were prepared kaolin clay through phase inversion/sintering technique and modified by three types fluoroalkylsilane (FAS) molecules (C6, C8, C10) at different immersion times (6, 24, 48,72 h) ca...

No. # 121 Determination of Hollow Cathode Plasma Contactor System Requirements using an Electrodynamic Tether System Simulation Tool One application of bare electrodynamic tether systems is to deorbit spent satellites and debris from Low-Earth Orbit. In these systems a hollow cathode plasma contactor sub-system is used to form a plasma bridge between one end of the tether and the space plasma i...
