Abstract Engineering a catalytic membrane capable of efficiently removing emerging organic microcontaminants under ultrahigh flux conditions is significance for water purification. Herein, drawing inspiration from the functional attributes lymphatic vessels involved in immunosurveillance and fluid transport with minimal energy consumption, novel hierarchical porous engineered. This membrane, based on an innovative nitrogen‐rich conjugated microporous polymer (polytripheneamine, PTPA), synthesized using electrospinning coupled situ polymerization approach. The resulting bioinspired channels comprises thin layer (≈1.7 µm) crosslinked PTPA nanoparticles covering interconnected electrospun nanofibers. unique design creates intrinsic angstrom‐confined system activating peroxymonosulfate (PMS) to generate 98.7% singlet oxygen ( 1 O 2 ), enabling durable highly efficient degradation microcontaminants. Additionally, presence mesoporous structure between macroporous within interwoven nanofibers enhances mass transfer efficiency facilitates high rates. Notably, prepared demonstrates enduring high‐efficiency performance superior permeance (>95% >2500 L m −2 h −1 bar ) sustained over 100 h. work introduces pathway high‐performance membranes removal

Potassium metal batteries (KMBs) hold promise for stationary energy storage with certain cost and resource merits. Nevertheless, their practicability is greatly handicapped by dendrite-related anodes, the target design of specialized separators to boost anode safety in its nascent stage. Here, we develop a thermally robust biopolymeric separator customized via solvent-exchange amino-siloxane decoration strategy render durable safe KMBs. Through experimental investigation theoretical computation, reveal that optimized porosity surface functionalization could manage ion transport interfacial chemistry, thereby enabling efficient K+ diffusion favorable solid electrolyte interphase achieve prolonged cycling stability (over 3000 h). The thus-assembled full cell retains 80% initial capacity after 400 cycles at 0.5 A g–1. heat-proof property designed further demonstrated. Our separator, affording multifunctional features, provides an appealing solution circumvent instability issues associated potassium batteries.

Abstract As the global energy structure transforms and renewable rapidly develops, rechargeable batteries are increasingly focus on high density, rapid charge/discharge rates, enhanced safety performance, particularly in extreme environments. Lithium metal (LMBs) have emerged as a significant research area recent years owing to capacity low electrochemical potential of lithium (Li). However, challenges, uncontrolled Li dendrite growth, unstable solid electrolyte interface separator puncture/interface incompatibility, greatly impact battery life lead failure, thus impeding commercialization. This review presents thorough analysis key challenges facing stable LMBs from multiple perspectives, alongside regulatory strategies. The methods include anode, interface, solid/liquid electrolytes, separators, pressure artificial intelligence. An in‐depth discussion operational mechanism, advantages/drawbacks is provided. Additionally, it offers succinct overview anticipated future trends challenges. A comprehensive numerous documents studies has been conducted summarize number published papers unique characteristics corresponding provides valuable recommendations for practical application other high‐energy‐density (Sodium, Potassium, Magnesium, Zinc), thereby contributing effectively implementation national strategic planning new sector.
