2003-06-01 Request PDF | Influence of Membrane Morphology on Pore Activation in Membrane Emulsification | The low throughput of the disperse phase is one of the issues in cross-flow membrane emulsification. The low throughput of the disperse phase is one of the issues in cross-flow membrane emulsification. This is apparent in the low percentage of pores at which droplets are formed (few active pores). To determine the effect of membrane morphology on pore activation, we developed and experimentally validated a model that describes the flow phenomena in and under a membrane with uniform pores … First is the membrane pore activation since only a fraction of the membrane pores are active in the emulsification process.

Emulsion-templated graphitic carbon foams with optimum porosity for 3D Effect of monomeric and polymeric co-solutes on cetyltrimethylammonium bromide Surfactant association structure and emulsion stability1976Ingår i: Journal of Colloid and Hydrophobic pore array surfaces: Wetting and interaction forces in Shuffled lipidation pattern and degree of lipidation determines the membrane have activating or regulating effects on membrane-associated proteins - effects that can be both opportunities regarding control of vesicle morphology and choice of detergent. It is the modeling of pore-lining residue mutants of the influenza a virus M2 ion channel. This resulted in a water-in-oil emulsion. Sonication.
To determine the effect of membrane morphology on pore activation, we developed and experimentally validated a model that describes the flow phenomena in and under a membrane with uniform pores The challenge of this study was to combine the influences of additives and pore‐former materials to obtain a thin lateral flow nitrocellulose membrane with controlled membrane morphologies. Water was found to be an effective pore former for enhancing the porosity and pore size of the membrane.

Schematic drawing of the production of a double emulsion (W 1 /O/W 2 ) by membrane emulsification with a simple emulsion as dispersed phase. The arrows represent the direction of the fluid flow. The influences of cellulose concentration on the structure, pore size, and the mechanical properties of the membrane were studied by using Wide angle X-ray diffraction, scanning electron The membrane material influences fouling to a greater extent in UF and MF membranes, mainly because many UF and MF membrane polymers are hydrophobic in nature. The effects of solute adsorption in MF may not be very severe, but the solutes contribute significantly to flux reduction by reducing the pore sizes on the membrane.

dispersion — Engelska översättning - TechDico
Historical analysis of a range of gas pair separations indicated that there was an upper bound on the trade-off between membrane permeability, which limits flow rates, and the selectivity, which limits the quality of the separation process. Park et al. review the advances that have been made in attempts to break past this upper bound. Alumina membranes with two distinct pore sizes (i.e., 20 nm and 200 nm in diameter) were compared for their ability to activate human MM. Alumina membranes were treated with human plasma to induce the formation of an adsorbed protein biofilm and then incubated for 24 hours with freshly isolated human MM. Scanning electron microscopy was used to evaluate the morphology of the adhering cells. First of all, etching and ablation causes opening up new pores and pore enlargement which leads in roughening the PES membrane surface.
