Unraveling MXene Oxidation Mechanisms Under Realistic Gas Environments by In Situ Gas‐Cell TEM

Advanced Functional Materials, EarlyView.
Real‐time visualization of MXene degradation reveals a fundamental oxidation mechanism under oxygen and moisture environments. Using in situ gas‐cell electron microscopy, this study demonstrates that oxygen degradation drives a thermodynamically controlled high‐temperature transformation into mixed rutile/anatase phases.

Replicated transfer matrix analysis of Ising spin models on 'small world' lattices

, 2004
We calculate equilibrium solutions for Ising spin models on `small world' lattices, which are constructed by superimposing random and sparse Poissonian graphs with finite average connectivity c onto a one-dimensional ring.

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Spontaneous symmetry breaking on graphs and lattices

Journal of Physics: Complexity
Spontaneous symmetry breaking (SSB) is a cornerstone of modern physics, defining a wealth of phenomena in condensed-matter and high-energy physics, and beyond. It requires an infinite number of degrees of freedom, and even then, for continuous symmetries,

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...
