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 …

as the dispersed phase. Interestingly, the results have shown that the morphology can be controlled not only by adjusting experimental parameters specific to the membrane emulsification step such as membrane pore size and pressure, but also by changing the nature of organic solvent. Therefore, pores formed after KOH activation can allow the facile mass transport of reactants and products (H 2 O, OH −, O 2 and H 2). Additionally, the pores mitigate diffusion limitations and are favorable for easy formation of the interfacial area between active sites and reactants, eventually increasing the overall electrolyzer Nanoparticles via Cross-Flow Membrane Emulsification Jae Man Shin1†, Minsoo P.

Kim*,1 1 Department of Chemical and Biomolecular Engineering, Korea Advanced Institute of Science and Technology (KAIST), Daejeon, 305-701 Republic of Korea However, for the 3 μm pore size membranes, at a similar cross-membrane pressure and for a similar formulation, we can expect that a larger fraction of the pores are active. Obviously, if more pores are active, then the mean distance between two growing drops on the membrane surface at any given time will be reduced and the possibility of neighbouring drops interacting will be increased. 2018-04-27 In the study of Yasuno and colleagues , in which actually no cross-flow was applied and spontaneous emulsification was allowed to take place, very low pore activation (0.3%–0.5%) was found, which could very well be caused by wettability changes that prevent inflow of the continuous phase into the membrane. Among other parameters, pore size of the membrane, pressure of the disperse phase, and adsorption kinetics of the emulsifier influence the results of emulsification.

However, little is known about the fouling mechanism of the ceramic membrane during O/W emulsion treatment. This paper investigated how stabilization surfactants of O/W emulsions influence the irreversible fouling of ceramic membranes during ultrafiltration.

Equipment for electro-optical studies of temperature-activated influence emulsion stabilisation through contact angles and e.g., characterisation of pore-structure and connectivity for fluid flow The Division of Building Materials currently has two pressure plate cells and one pressure membrane cell.

The synthetic procedure of AAO membranes enables significant tunability of the various porosity parameters (channel diameter 5–400 nm, interpore distance 20–600 nm, porosity 10–50%, thickness from 500 nm to 300 µm The effects proved stronger for PA 10 kDa than for 50 kDa. In fact, similar pretreatment procedures caused larger pore size and pore size distribution for PA 10 kDa than for 50 kDa. The properties of emulsions in terms of droplet size distribution reflected the membrane pore … The swirl flow membrane emulsification method involved the generation of a centrifugal kind of flow in the continuous phase.

Abstract In this study, a rotating membrane emulsification setup incorporating a 6.1μm pore diameter SPG membrane was used to produce O/W emulsions of average droplet sizes between 23.4 and 216.6μm. All emulsions consisted of 10vol% of sunflower oil or silicone oil stabilised by 1wt% Tween 20. The transmembrane pressure (0.1–1.8bar), rotational speeds (100–2000RPM) annular gap width (5
