Quantifying Efficiency Roll‐Off Factors in Quantum‐Dot Light‐Emitting Diodes

Advanced Science
The application of quantum‐dot light‐emitting diodes (QLEDs) is hindered by efficiency roll‐off at high current densities. Factors contributing to this roll‐off include Auger recombination, electric field‐induced quenching, Joule heating, and electron ...

Comparison of different X‐ray‐based scanning electron microscopy methods to detect sub‐nanometre ultra‐thin InAs layers deposited on top of GaAs

Journal of Microscopy, EarlyView.
Abstract We compare three different methods of X‐ray analysis in a scanning electron microscope (SEM): energy‐dispersive X‐ray spectroscopy (EDX), wavelength‐dispersive X‐ray spectroscopy (WDX) and micro X‐ray fluorescence (μXRF). These methods are all applied to the same gallium arsenide (GaAs) wafer with a 0.8 nm layer of indium arsenide (InAs) on ...

Binary Active Sites Construction of More Stable and Higher Dispersed Mn‐Doped CuOx/CeO2 Catalysts via Ethylene Glycol‐Assisted Impregnation for Highly Efficient CO Oxidation

cMat, Volume 3, Issue 2, June 2026.
ABSTRACT The copper–cerium catalyst has shown brilliant performance in catalytic CO oxidation at low temperatures. However, the current research focus is needed to comprehensively understand the impact of doped elements and metal species content on the structure and performance of the catalysts.

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, Volume 58, Issue 6, Page 387-399, June 2026.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 6, Page 2097-2115, June 2026.
ABSTRACT This study explores the impact of surface condition on high‐cycle fatigue performance of a high‐nitrogen martensitic tool steel manufactured through powder metallurgy and hot isostatic pressing. In near‐net manufacturing applications, acid‐leaching pickling treatment and/or machining is used as a post‐treatment to remove the powder container ...

Boron‐Doped Carbon Coatings Stabilize Cu+/Cu0 Interfaces to Promote Multicarbon Formation in CO2 Electroreduction

ChemSusChem, Volume 19, Issue 10, 27 May 2026.
The boron‐doped carbon coating of a dual‐phase Cu2O(Cu) catalyst stabilizes abundant Cu+/Cu0 interfaces during CO2 electrolysis, enhancing *CO coverage and promoting C2+ formation. The catalyst achieves a C2+ Faradaic efficiency of 83.4%, a partial current density of 460 mA cm−2, and operates stably for at least 42 h.

Enhancing Catalyst Stability for Magnetically Induced Aqueous Catalysis: Functionalization with a Hydrosoluble Zwitterionic Amidinate Ligand

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
A stable, water‐compatible catalyst for the magnetically induced hydrogenation of biomass‐derived compounds in aqueous media was developed by functionalizing magnetic core–shell FeCo@Ni nanoparticles with a new hydrosoluble zwitterionic amidinate ligand via ligand exchange in a biphasic system. The efficient conversion of biomass‐derived compounds into

Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...
