Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

Van der Waals Gap‐Confined Molecular Engineering of MoS2 for Selectivity‐Enhanced and Humidity‐Tolerant Gas Sensing

Advanced Science, EarlyView.
Molecular confinement within van der Waals gaps of MoS2 is established as a powerful design strategy for selective and stable chemical sensing. Ethanol‐confined films simultaneously tune electronic doping, surface wettability, and sulfur vacancy configurations, suppressing water interference while enhancing NO2 adsorption.

Magnetic‐Field‐Tuned Spin‐Dependent D‐Band and Bifunctionality in L10‐FeCoPt for Enhanced Methanol Oxidation

Advanced Science, EarlyView.
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...
