Active Phase of Nickel Electrocatalysts Driving Alkaline Hydrogen Evolution

Advanced Materials, EarlyView.
Using depth‐resolved and operando spectroscopic measurements coupled with electrochemical mass spectrometry, the authors uncover the critical role of sub‐surface oxidised species in increasing the activity and durability of Ni‐based cathodes for hydrogen evolution.

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Multi‐Stimuli Responsive Angstrom‐Scale Two‐Dimensional Channels of Natural Layered Materials

Advanced Materials, EarlyView.
Å‐scale ion channels naturally formed within the interlayers of vermiculite clay enable ionic current modulation in response to mechanical, chemical, and electrical stimuli. Coupled pressure and electric fields induce reversible streaming current (Istream) polarity inversion, which is explained by a modified surface charge regulation model.

Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector

, 2016
Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior.

Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

Advanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.
