Organic solvent nanofiltration (OSN) is gradually expanding from academic research to industrial implementation. The need for membranes with low and sharp molecular weight cutoffs that are able operate under aggressive OSN conditions increasing. However, the lack of comparable uniform performance data frustrates screening membrane selection processes. Here, a collaboration presented between sev...

Artificial Cells In article number 2202962, Yoon-Kyoung Cho and co-workers discuss the latest advances in cell membrane-engineered micro or nanoreactors that simulate biochemical compartments, signaling cascades, energy generation, growth, reproduction, adaptability. These reactors have potential to provide hybrid solutions for pharmaceutical drugs, biosensors, novel materials, microreactors.

Ocular Surfaces In article number 2200283, Jinyao Liu, Lu Lu, Yan Pang, and co-workers describe a strategy of forming long-acting protective ocular surface against external viral invasion by instilling adhesive dual-antiviral nanoparticles, which are enabled coating antiviral agent-loaded nanoparticles with “double-lock” hybrid cell membrane.

Proton exchange membrane fuel cells (PEMFCs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. In this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/La2Ce2O7 (PVA-LC) with the aim of increasing the water uptake and proton conductivity. Glutaraldehyde (GA) was used as cross linking agent ...

1. Introduction Mesoporous materials with ordered arrays of uniform nanochannels of a controllable size have wide-ranging applications, one of which is membrane separation. In order to be used as a membrane for size-exclusive separation of molecules, it is necessary to synthesize a defect-free structure with continuous nanoporosity. Mesoporous silica and porous anodic alumina have been extensiv...

Cyclooxygenase isoform-2 (COX-2) and microsomal prostaglandin E(2) synthase-1 (mPGES-1) are inducible enzymes that become up-regulated in inflammation and some cancers. It has been demonstrated that their coupling reaction of converting arachidonic acid (AA) into prostaglandin (PG) E(2) (PGE(2)) is responsible for inflammation and cancers. Understanding their coupling reactions at the molecular...
