Revealing How Acid Sites Enhance the Electrocatalytic Glycerol Oxidation Performance on Pt Loaded Zeolite‐Carbon Composite Materials

Advanced Materials, EarlyView.
In the work reported herein, the catalytic effects of acid sites on electrocatalytic glycerol oxidation reaction are investigated by using a novel catalytic material system that integrates Pt metal sites with acidic Al sites. Abstract The catalytic role and function of acid sites in solid acid catalysts, such as zeolites, are well understood in the ...

Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity

Advanced Materials, EarlyView.
Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...

Sustainable Self‐Healing of Perovskite Solar Cells Using Dendrimers as Volatile Reservoirs

Advanced Materials, EarlyView.
Sustainable self‐healing perovskite solar cells (PSCs) are developed through the incorporation of dendrimers with unique molecular structures and appropriately placed functional groups. Notably, even after subjecting ten harsh degradation and recovery cycles, these PSCs maintain 90% of their initial power conversion efficiency (>26%).

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

Advanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This
