Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

Advanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

Strong Metal‐Support Interaction Driven Janus Reconstruction in PtRu Alloys for Low‐Temperature Hydrogen Storage

Advanced Science, EarlyView.
Strong metal‐support interactions (SMSI) drive the spontaneous segregation of RuPt alloy into Janus nanoparticles on CeO2, spatially partitioning Pt‐rich domains for H2 dissociation and Ru‐rich domains for toluene adsorption. This Janus nanocatalysts yield a turnover frequency of 10 906 h−1 for toluene hydrogenation at 50 °C, which is 6.7 times that of

Atomistic Kinetics of Dislocation‐Mediated Grain Growth in Monolayer MoS2

Advanced Science, EarlyView.
Atomic‐resolution in‐situ heating microscopy directly visualizes dislocation‐mediated grain boundary migration and grain growth in monolayer MoS2. Mobile grain boundaries migrate through collective motion of Mo 5|7 dislocations, whereas S 5|7 defects remain largely immobile.

Water‐Soluble POSS Promotes Concurrent Coalescence and Crosslinking for Multiscale‐Reinforced, Coalescent‐Free Waterborne Coatings

Advanced Science, EarlyView.
Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...

High-Energy Electron Confinement in a Magnetic Cusp Configuration

Physical Review X, 2015
We report experimental results validating the concept that plasma confinement is enhanced in a magnetic cusp configuration when β (plasma pressure/magnetic field pressure) is of order unity.

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

Advanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...
