Competition between vacancy creation and filling in defect-engineering of hBN

Abstract Hexagonal boron nitride (hBN) has recently become the focus of intense research as a material that can host quantum emitters. It is known that such emission is related to point defects, but in order to conclusively correlate specific defects to their spectra, having cont...

Dipole–dipole interaction facilitates anion-rich solvation structures in polymer electrolytes for solid-state lithium metal batteries

Polymer electrolytes are vital for safe and high-energy–density lithium metal batteries but face challenges from interfacial instability and Li dendrites. Here, we report a molecular design exploiting dipole–dipole interactions to tailor Li + solvation structures and interfacial...

Epitaxial MgSnN 2 on 4H‐SiC (0001): An Earth‐Abundant Nitride for Green Optoelectronics and Photovoltaics

ABSTRACT Group II–IV‐Nitrides has emerged as a novel class of Earth‐abundant semiconductors. Owing to their tunable bandgaps these materials are attractive candidates for replacing expensive Ga‐based alloys in photovoltaics and green‐gap optoelectronics. In this work, epitaxial g...

Comment on “The elusive fluid‐and‐crystal coexistence state in simulations of monodisperse, hard‐sphere colloids”

Abstract In a recent article [1], Wang et al. discuss the absence of simulations of monodisperse hard spheres in which a metastable fluid spontaneously nucleates into a stable fluid‐crystal coexistence. Here, we show that such a simulation can be readily accomplished with standar...

Quantifying the Correlation Between Capacity Utilization and Electrolyte Dosage for Ultrahigh‐Energy‐Density 769 Wh Kg −1 Rechargeable Lithium Metal Batteries

ABSTRACT The pursuit of high‐energy‐density lithium metal batteries requires simultaneous optimization of electrode architecture, electrolyte formulation, and interfacial stability. Here, we establish a fundamental parameter g(σ e , D e ) that quantifies the relationship between...

Dual Oxygen Precursors Boosting the Ionic Conductivity of Glassy Electrolytes for All‐Solid‐State Sodium Batteries

ABSTRACT Amorphous halide‐based solid electrolytes (SEs) are promising candidates for all‐solid‐state Na batteries (ASSNaBs) due to their structural flexibility and favorable mechanical properties. Among them, aluminum‐based halide electrolytes are particularly attractive owing t...

A BifunctionalKeggin-Type POM-Based Cu(II) Complexfor Oxidizing Phenolic Compounds and Trace Detecting Phenol

Abstract Given the broad applications of p-benzoquinones in medicine and materials, developing efficient and environmentally benign catalysts for their synthesis from phenolic compounds is of great significance. Herein, a polyoxometalate (POM)-based Cu(II)-complex (POMOC), formul...
