NH3‐Guided Low‐Temperature Nanostructural Refinement Boosts Visible‐Light‐Driven H2O2 Synthesis in Ionic Carbon Nitrides

Advanced Materials, EarlyView.
A nanostructural refinement strategy is reported for KPHI photocatalysts using NH4Cl in a molten salt environment to induce coherent domain fragmentation and controlled cyano defect formation. This dual modification promotes n→π* transitions, enhances charge separation, and accelerates ORR kinetics, yielding exceptional AQY values of 49% (410 nm) and 5%

Chip‐Scale Graphene/IGZO Cold Source FET Array Enabling Sub‐60 mV dec−1 Super‐Steep Subthreshold Swing

Advanced Materials, EarlyView.
Super‐steep subthreshold swing (SS) below 60 mV dec−1 is demonstrated in graphene/IGZO cold source transistor arrays. Linear density of states with Dirac cone in graphene suppressed the Boltzmann thermal tail, while high‐k HfO2 dielectric having small body factor enhanced gating efficiency, hereby further reducing SS. An average SS of ≈46.4 mV dec−1 is

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

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 ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
