Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

X-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...

Quartz-tuning-fork enhanced photothermal spectroscopy for ultra-high sensitive trace gas detection

, 2018
A gas sensing method based on quartz-tuning-fork enhanced photothermal spectroscopy (QEPTS) is reported in this paper. Unlike usually used thermally sensitive elements, a sharply resonant quartz-tuning-fork with the capability of enhanced mechanical ...

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 12, Page 1552-1563, December 2026.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, Volume 36, Issue 89, 5 November 2026.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...
