Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells
Advanced Materials, EarlyView.A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Mass Shootings, Community Mobility, and the Relocation of Economic Activity [PDF]
arXivUsing foot traffic data for over 150,000 points of interest (POIs) near the sites of 42 mass shootings (2018-2022, U.S.), we evaluate the spatial-temporal impact of the tragic events on community mobility and relocation of economic activities. Visits to nearby POIs decrease, while farther away POIs experience increased foot traffic, implying that ...

Advanced Materials, EarlyView.Carbon‐based piezoelectric materials are systematically categorized based on their structural and functional properties. The mechanisms of stress‐induced charge transfer are elucidated, and their applications are explored across three key domains: piezoelectric catalysis for energy conversion and environmental remediation, piezoelectric biomedical ...

Advanced Materials, EarlyView.Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...

Revisiting Shooting Point Monte Carlo Methods for Transition Path Sampling [PDF]
arXivRare event sampling algorithms are essential for understanding processes that occur infrequently on the molecular scale, yet they are important for the long-time dynamics of complex molecular systems. One of these algorithms, transition path sampling (TPS), has become a standard technique to study such rare processes since no prior knowledge on the ...
