the performances of two-phase polymer-liquid pebax®/polyethylene glycol (peg) and three-phase polymer-liquid-solid pebax®/peg/mwnt thin film composite membranes for co2 and ch4 permeation were studied. the effect of temperature and mwnt/pebax® ratio on single gas (co2 and ch4) permeability was investigated. the permeation of both gases was measured at different temperatures from 303 to 323 ˚k. ...

Liquid/liquid separation after monophasic reactions is a viable way to use and recover polysiloxane-supported catalysts.

Formation of liquid-ordered domains in model membranes can be linked to raft formation in cellular membranes. The lipid stoichiometry has a governing influence on domain formation and consequently, biochemical hydrolysis of specific lipids has the potential to remodel domain features. Activation of phospholipase A(2) (PLA(2)) by ternary model membranes with three components (DOPC/DPPC/Cholester...

Liquid membranes usually consist of an extracting agent (carrier) in an organic solvent which separates "feed" and "stripping" phases containing aqueous solutions of the solute of interest and a stripping agent, respectively. In supported liquid membranes (SLMs) the membrane solution is immobilised into a thin solid microporous support, between the feed and stripping phases where transport is f...

bibliometric, and scientometric approaches are used to provide appropriate tools for evaluating scientific products at local, national, and international levels. iran, the same as other countries, has many universities and research centers in the field of engineering that iran's most of the scientific products account for the field of engineering. this study is a descriptive approach using scie...

Monolithic support materials with the mechanical resistance and thermal conductivity of SiC as well tunable surface chemistry textural properties were developed for their use in catalytic membrane reactors. After heat treatment, extruded monoliths have a monomodal distribution macropores few μm diameter depending on particle size starting material. A macroporous, defect-free, smoother skin was ...
