Revealing the Origin and Nature of the Buried Metal‐Substrate Interface Layer in Ta/Sapphire Superconducting Films

Advanced Science, EarlyView.
The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Deep‐UV Light‐Emitting Based on the hBN:S/hBN: Mg Homojunction

Advanced Science, EarlyView.
S‐atoms are selected as donor dopants to achieve the n‐type conductivity of the hBN film. A theoretical model of S‐doping hBN using DFT calculation and experimentally prepared S‐doped hBN multilayers with a recorded doping concentration of 1.21% is established.

Photopatternable PEDOT:PSS Hydrogels for High‐Resolution Photolithography

Advanced Science, EarlyView.
A photosensitive biphasic conducting polymer hydrogel (PB‐CH) is rationally designed with PEDOT:PSS as the conductive phase and a light‐sensitive matrix as the mechanical phase. Such a PB‐CH offers a unique combination of excellent conductivity (≈30 S cm⁻¹), robust mechanical performance (with stretchability up to 50%), and high photopatternability ...

Advanced Solid Lubrication with COK‐47: Mechanistic Insights on the Role of Water and Performance Evaluation

Advanced Science, EarlyView.
This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...

Comparison of the performance of a microwave plasma torch and a gliding arc plasma for hydrogen production via methane pyrolysis

Plasma Processes and Polymers, Volume 20, Issue 1, January 2023., 2023
Hydrogen production via plasma methane pyrolysis is investigated using a microwave plasma torch (MPT) and a gliding arc plasmatron (GAP). The performance of the two plasma sources in terms of methane conversion, product spectrum, and energy efficiency is compared. The physical and chemical properties of the produced carbon particles are compared.

A Bias‐Tunable Multispectral Photodetector Based on a GaN/TexSe1‐x Homo‐Type Heterojunction with a Unidirectional Barrier

Advanced Science, EarlyView.
A bias‐tunable multispectral photodetector based on a TexSe1‐x/GaN homo‐type heterojunction with a unidirectional barrier is proposed. By modulating the bias polarity and magnitude, the device's spectral response range can be extended from UV to the SWIR region.

Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

Advanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

Advanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.
