We explored the potential for membrane materials to reduce energy and carbon requirements for the separation of aliphatic hydrocarbon feedstocks and products. We developed a series of fluorine-rich poly(arylene amine) polymer membranes that feature rigid polymer backbones with segregated perfluoroalkyl side chains. This combination imbues the polymers with resistance to dilation induced by hydrocarbon immersion without the loss of solution-based membrane fabrication techniques.

One of the primary challenges in commercializing perovskite solar cells (PSCs) is achieving both high power conversion efficiency (PCE) and sufficient stability. We integrate wafer-scale continuous monolayer MoS buffers at the top and bottom of a perovskite layer through a transfer process. These films physically block ion migration of perovskite into carrier transport layers and chemically stabilize the formamidinium lead iodide phase through strong coordination interaction.

The well-known inhibitory strength of 3d metal Schiff base complexes against urease enzymes has long been acknowledged, but their untapped potential to act as ureolytic mimics of active metallobiosites remained unexplored. To break the new ground, we present pyrrolidine-based mononuclear Ni(II)-azide complex {[NiL(HL)(N)]·1.5(HO)} using the N,N,O donor ligand, namely ()-4-bromo-2-(((2-(pyrrolidin-1-yl)ethyl)imino)methyl)phenol.

Article Synopsis
- Solid-state polymer electrolytes (SPEs) are gaining attention for sodium metal batteries (SMBs) due to their flexibility and lower interfacial resistance, but they struggle with sodium ion conductivity and unstable interfaces.
- A novel composite electrolyte called PPNM is created by integrating a 3D copper metal organic framework (Cu-MOF) with polyacrylonitrile (PAN) fibers and polyethylene oxide (PEO), enhancing ionic conductivity and sodium ion movement.
- The improved stability and performance of the PPNM electrolyte lead to strong cycling results for Na3V2(PO4)3@C/PPNM/Na full cells, making it a promising strategy for advancing solid-state SMB technology.

Gouty arthritis is one of the most common forms of inflammatory arthritis and has brought a significant burden on patients and society. Current strategies for managing gout primarily focus on long-term urate-lowering therapy. With the rapid advancement of point-of-care testing (POCT) technology, continuous monitoring of gout-related biomarkers like uric acid (UA) or inflammatory cytokines can provide rapid and personalized diagnosis for gout management.
