Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride

Rare Metals, EarlyView.
ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

A Micro‐Nano Flower‐Like Na3V2(PO4)3@C Constructed by Polar‐Driven H‐Bond Engineering Toward High‐Rate Sodium Storage

Rare Metals, EarlyView.
ABSTRACT The polyanionic compound Na3V2(PO4)3 (NVP) has emerged as a competitive cathode material for sodium‐ion batteries (SIBs), owing to its high‐voltage redox activity (3.4 V vs. the Na+/Na reference couple) and NASICON‐type framework that enables superior ionic conductivity.

A High Capacity‐Long Cycling Concurrent Strategy of Ti3C2/MgH2 for Lithium Storage

Rare Metals, EarlyView.
ABSTRACT The excellent electrical conductivity and superior cycling stability render Ti3C2 MXene a promising Li ion battery anode. Nevertheless, the practical implementation of Ti3C2 MXene in commercial applications faces significant challenges, predominantly due to the low specific capacity.

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

Small, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

Small, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

MnBr2${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super‐Moiré

Small, EarlyView.
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Thermal Transport Properties of W2TMB2 Solid Solutions (TM = Fe, Co, Ni)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Thermal transport properties of W2TMB2 (TM: Fe, Co, Ni) and their solid solutions, as well as electron backscatter diffraction measurements, show interesting particularities depending on the TM type and content. In this work, thermal transport properties of W2FexCo1‐xB2, W2FexNi1-xCoB2, and W2NixCo1‐xB2 (x: 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were ...

Hawking radiation from Feynman diagrams [PDF]

Physical Review D, 1999
The aim of this letter is to clarify the relationships between Hawking radiation and the scattering of light by matter falling into a black hole. To this end we analyze the S-matrix elements of a model composed of a massive infalling particle (described by a quantized field) and the radiation field.
