Volatile Sieving Using Architecturally Designed Nanochannel Lamellar Membranes in Membrane Desalination.

Thermally driven membrane desalination processes have garnered significant interest for their potential in the treatment of hypersaline wastewater. However, achieving high rejection rates for volatiles while maintaining a high water flux remains a considerable challenge. Herein, we propose a thermo-osmosis-evaporation (TOE) system that utilizes molecular intercalation-regulated graphene oxide (GO) as the thermo-osmotic selective permeation layer, positioned on a hydrophobic poly(vinylidene fluoride) fibrous membrane serving as the thermo-evaporation layer.

State Key Laboratory of Roll Composite Materials, Sinosteel Xing Tai Mechanical Roll Co., Ltd., No. 1 Xinxing West Street, Xingtai 054000, China.
Composite roll produced through casting methods typically remain in the as-cast state after forming. During the preparation process, extended exposure to high temperatures often results in microstructural coarsening at the interface and surface layers, restricting their mechanical performance. To overcome this limitation, we developed a novel vacuum billet forging process for the fabrication of composite rolls.

This review analyzes the primary etiological factors of diffuse lamellar keratitis following various laser corneal refractive surgery techniques. The use of advanced diagnostic methods such as optical coherence tomography, confocal microscopy, and immunohistochemical methods has allowed for the identification of the main pathogenetic mechanisms underlying this condition, which will help improve the prevention, as well as assist with the development of optimal treatment strategies for this complication.

This manuscript reports on the effect of different bile salts concentration on the gastrointestinal digestion of casein and casein-agar hybrid systems and evaluates the effect on the nanostructural assembly of the digestion products through the application of advanced small angle X-ray scattering analysis (SAXS). The results showed that bile salts promote the hydrolysis of micellar casein upon in vitro gastrointestinal digestions. It is noteworthy that in the presence of agar, bile salts interact with the polysaccharide, leading to a reduction in their proteolytic activity.

Exploring the transfer ability of proton carriers at different relative humidity (RH) is vital for the rational design and development of high-performance proton exchange membranes (PEMs). However, the highly humidity-dependent transfer channel and random carrier distribution disqualify most membrane materials. Herein, a series of MIL-53 metal-organic framework (MOF) nanosheets with stable, quantifiable pore structures and different conducting groups are prepared through postsynthetic ligand exchange, followed by spin coating to assemble lamellar membranes.
