Microwave‐assisted one‐pot synthesis of MXene–rGO–Au nanocomposites for high‐sensitivity dopamine detection

VIEW, EarlyView.
MXene/rGO/Au nanocomposites on a modified glassy carbon electrode enable rapid, sensitive DA detection with strong selectivity and reliable real‐sample recovery. The one‐pot microwave synthesis delivers a conductive, high‐performance platform for practical electrochemical DA sensing.

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 ...

Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.

Prevalence of novel psychoactive substances in selected clinical urine specimens submitted for drug monitoring

Journal of Forensic Sciences, EarlyView.
Abstract Novel psychoactive substances (NPS) are compounds emerging as alternatives to more established drugs of abuse. They are constantly changing and being modified, which makes their detection difficult. The study objective was to determine the prevalence of NPS in selected clinical specimens. Deidentified urine specimen remnants were analyzed that
