Front Propagation Through a Perforated Wall

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

New‐Generation Integrated Devices: Multiple‐Energy Utilization and Integration Systems Based on Perovskite Photovoltaics

open access: yesEcoEnergy, EarlyView.
This review highlights emerging integrated energy systems based on perovskite photovoltaics, including PSC–thermoelectric, photovoltaic–electrochemical, self‐charging, and building‐integrated architectures. By coupling multiple energy conversion and storage pathways, these multifunctional platforms enable enhanced solar utilization, improved stability,

Synergistic Crystallinity Reduction and Lewis Acidic Promotion by PVDF‐Al(OH)3 for High Room‐Temperature Ionic Conductivity in PEO‐Based Composite Quasi‐Solid Electrolytes

open access: yesEcoEnergy, EarlyView.
Through the synergistic effects of crystallinity reduction and Lewis acidic promotion enabled by PVDF‐Al(OH)3, a PEO‐based composite quasi‐solid electrolyte has been developed, achieving both a high Li+ transfer number and superior ionic conductivity. It endows lithium metal batteries with excellent cycling stability at room temperature, even without ...
