Frontispiece: In article number 2000776, Andriy Horechyy, Iryna Yevchuk, Andreas Fery, and co-workers present a series of hybrid proton conducting membranes composed covalently cross-linked interpenetrating polymeric silica networks. The effects monomer composition, sol–gel composition fraction on performance are investigated discussed. These novel hold promise for the application in direct met...

To improve the CO2/N2 separation performance, mixed-matrix carbon molecular sieve membranes (mixed-matrix CMSMs) were fabricated and tested. Two carbon-based fillers, graphene oxide (GO) activated (YP-50F), separately incorporated into two polymer precursors (Matrimid® 5218 ODPA-TMPDA), resulting CMSMs demonstrated improved CO2 permeability. The improvement afforded by YP-50F was more substanti...

Permporometry IS a method by which the characterlstlcs of the mterconnectmg ‘active’ pores of an ultrafiltration membrane can be measured It 1s these ‘active’ pores that are responsible for the actual membrane performance Apphcatlon of permporometry on different membrane types, including ceramic as well as polymeric membranes, shows that the method can provide obJectwe mformatlon on the ‘active...

Surface modification of polymeric scaffolds for biomedical applications is a versatile and widely used method to improve interactions between cells. Specifically, chemical immobilization proteins provides significant advantages such as stable biocompatible properties, however, it generally requires expensive instruments or complex steps. In this study, the facile presented that changes poly (l-...

The carbon dioxide (CO2) separation can be enhanced by using modified materials like a deep eutectic solvent (DES) mesoporous silica SBA-15 in polymeric support i.e polysulfone via mixed matrix membranes (MMMs). pure and DES are potential candidates for the CO2 capturing their combination has not been reported yet. In this work, fresh was synthesized combining equal concentrations of Decanoic a...

A protein of Mr 94000 was isolated from detergent-solubilized bovine intestinal, liver and mammary-gland membranes. It binds immunoglobulin M and also undergoes proteolytic fragmentation in a similar manner to bovine secretory component (Mr 74000). The affinity-purified membrane protein is therefore most likely to be the bovine epithelial receptor for polymeric immunoglobulin. A structural mode...

Water pollution is a growing environmental issue which severely threatens human health. Consequently, development of novel materials for water purification and waste treatment is an important research topic. Functional nanomaterials exhibiting photocatalytic properties, along with a very high surface area, have been widely investigated, since these nanostructures are quite effective in the degr...

Global lack of clean water makes it essential that new technologies are developed for separation pollutants from raw water. Membrane has arisen as a promising solution among other conventional liquid-separation processes, such evaporation, distillation, and crystallization. Synthetic polymer membranes have been emphasized an important component in liquid processes due to their outstanding water...
