The immersion precipitation process makes most commercial polymeric membranes, which enjoy widespread use in water filtration and purification. In this work, a ternary Cahn-Hilliard formulation incorporating a Flory-Huggins homogeneous free energy function is used to model both initial diffusion and the liquid-liquid demixing stage of the immersion precipitation process, which determines much o...

Direct Ink Writing In article number 2300866, Leyu Wang, Malcolm Xing, and co-workers prepare, printed graphene oxide (GO)/reduced GO bilayer membrane for asymmetric structure with hydrophobicity hydrophilicity on two sides, leading to multifunctional applications in conformable ultra-thin cardiac patches, moisture-responsive soft robots, wearable electronics.

One of the research directions renewable energy sources is production biohydrogen from dark fermentation organic matter. During this process, since hydrogen produced along with a complex mixture other gases and vapors, gas requires further purification. relatively easy solution to problem might be utilization separation membrane modules given their low consumption, simple operation ease upscali...

The outer membrane of Gram-negative bacteria is a unique asymmetric lipid bilayer composed of phospholipids (PLs) in the inner leaflet and lipopolysaccharides (LPSs) in the outer leaflet. Its function as a selective barrier is crucial for the survival of bacteria in many distinct environments, and it also renders Gram-negative bacteria more resistant to antibiotics than their Gram-positive coun...

In the present study, asymmetric membrane capsules (AMCs) with two compartments were successfully developed for simultaneous delivery of two poorly water-soluble drugs, Atenolol and Amlodipine Besylate, by using solubility modulation approach. Scanning electron microscopy (SEM) before dissolution showed presence of outer dense region and inner porous region for the prepared asymmetric membrane ...

Ultra-small all-optical switches are of importance in highly integrated optical communication and computing networks. However, the weak nonlinear light-matter interactions in natural materials present an enormous challenge to realize efficiently switching for the ultra-short interaction lengths. Here, we experimentally demonstrate a submicron bidirectional all-optical plasmonic switch with an a...
