Synergistic Catalysis for Closed‐Loop Alcohol Refining: Concurrent H2 Evolution and Selective Oxidation

open access: yesEcoEnergy, EarlyView.
Photocatalytic, electrocatalytic, and photoelectrocatalytic systems exhibit a clear synergistic integration logic in closed‐loop alcohol refining—concurrently driving hydrogen evolution and selective alcohol oxidation to enable the directed conversion of alcohols into high‐value chemicals.

Infrared Absorption and Electron Spin Resonance Studies of Nanocrystalline Cubic Boron Nitride/Amorphous Hydrogenated Boron Nitride Mixed Phase Thin Films

open access: yes, 1995
Both infrared absorption (IR) and electron spin resonance (ESR) spectroscopies have been used to investigate the complicated structure of nanocrystalline cubic boron nitride/amorphous hydro-genated boron nitride thin films.

The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.

Intrinsic Metallic and Semiconducting Cubic Boron Nitride Nanofilms

open access: yes, 2016
We show by density functional theory calculations with both hybrid and semilocal functionals that cubic boron nitride (111) nanofilms are intrinsically metallic and even turn into semiconductors once the thickness is less than 0.69 nm, which is in sharp ...

Breaking the Temperature Barrier: Ultra‐Stable SiHfBCN Ceramic Coatings for High‐Temperature Pressure Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A 3D conductive net including HfC(N) conductive nanodomains and in‐situ carbon ribbons was generated within the amorphous SiHfBCN matrix by a new molecular‐level composition and microstructure design strategy, making a smooth and dense polymer‐derived SiHfBCN ceramic coatings exhibits excellent electrical conductivity, wide‐temperature sensing, cycling
