*New publication from EMSR* Airborne pathogens and pollution control typically necessitate multiple membranes, each specializing in efficient aerosol filtration, moisture regulation, or antimicrobial protection. Integrating all these functions into a single membrane is highly advantageous but remains inherently challenging due to material incompatibility and inevitable performance trade-offs. Here, we present a photoactive Janus nanofibrous membrane…

*New publication from EMSR* In this work, we highlight inorganic solid-state electrolytes (ISSEs), originally engineered for all-solid-state batteries, as highly selective, energy-efficient membranes for extracting lithium from seawater and brines, addressing rising demand and the vast but dilute oceanic resource. Surveying oxide, sulfide, and emerging halide (and related) chemistries, the review identifies oxide-based NASICON-like materials…

*New publication from EMSR* Osmotic energy, an infinite, clean energy source, can be efficiently harnessed through reverse electrodialysis using ion-selective membranes. While polymeric membranes are excellent candidates due to their solution-processability and scalability, their non-uniform pore architecture and high resistance limit their power density output. Here, an in situ space-confined synthesis strategy is proposed to…
