Rocksalt MgS solar blind ultra-violet detectors
AIP Advances, 2012 Studies using in-situ Auger electron spectroscopy and reflection high energy electron diffraction, and ex-situ high resolution X-ray diffraction and electron backscatter diffraction reveal that a MgS thin film grown directly on a GaAs (100) substrate by ...

Multichannel Photoluminescence of Graphene Quantum Dots Across Femtosecond to Cryogenic Timescales
Small, EarlyView.This study reveals how graphene quantum dots emit light across all relevant timescales, from femtoseconds to cryogenic steady states. By integrating optical Kerr gating, time‐correlated single‐photon counting, and low‐temperature photoluminescence, distinct intrinsic, surface, and defect‐related emission channels are temporally and spectrally ...

Bimetallic Bismuth‐Based Nanoparticles From Pseudo‐Tetrahedral Zintl Anions
Small, EarlyView.Bismuth‐based Zintl anions are explored as precursors for synthesizing bimetallic nanoparticles with tunable compositions and morphologies, including alloyed, core–shell, and Janus types. The resulting nanoparticles display composition‐dependent UV absorption.

Correlative Chemical Imaging to Reveal the Nature of Different Commercial Graphene Materials
Small Methods, EarlyView.Commercial graphene‐based materials from different sources and of varying complexities were investigated correlatively using commonly employed imaging techniques, including SEM, AFM, ToF‐SIMS, AES, and EDS. ToF‐SIMS combined with SEM was identified as the most effective combination for simultaneously resolving the complex morphology and chemical ...

steel research international, EarlyView.The study evaluates mill scale‐based briquettes, which meet industrial standards for shatter strength and exhibit a low decrepitation index. Despite their limited reducibility in nonisothermal reduction experiments, softening and melting results indicate potential application as a substitute for conventional acidic iron‐bearing materials for use in ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

High Cycle Fatigue Properties of PM‐HIPed High‐Nitrogen Tool Steel: Effect of Surface Condition
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.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 ...

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 ...

Engineering Hybrid Polymeric Gd2O3 Nanoparticles for Tumor‐Targeted Neutron Capture Therapy
ChemNanoMat, Volume 12, Issue 4, April 2026.Neutron capture therapy (NCT) stands as a transformative approach for precision oncology. The principle relies on tumor‐targeted isotopes, such as boron‐10 (10B) and gadolinium‐157 (157Gd), for generating cytotoxic high energy particles upon thermal neutron irradiation.
