Sulfide Detection by Gold-Amalgam Microelectrodes in Artificial Wastewater
Chemosensors, 2020 Gold amalgam microelectrodes (GAMEs) have been characterized and successfully calibrated to measure >1.5 mM (30 mg L−1) sulfide in artificial wastewater (AWW) using cathodic stripping voltammetry (CSV).

Clinical resolution of oral lichenoid lesions after amalgam replacement: A systematic review and meta-analysis of observational studies. [PDF]
J Oral Biol Craniofac ResIntroduction Oral lichenoid lesions (OLLs) can mimic oral lichen planus but are often linked to contact with dental amalgam. Replacement with biocompatible materials has been associated with lesion resolution, yet prior evidence lacked quantitative ...

Patch Test Reactions to Dental Materials: A Retrospective Single-Centre Study. [PDF]
Contact DermatitisIn this retrospective single‐centre study of 439 adults referred for suspected delayed‐type hypersensitivity to dental materials, 50.1% had at least one positive patch test reaction, most often to metals. Nickel (23.0%) and palladium (16.6%) pre‐dominated, whilst methacrylate positivity was uncommon (6.2%) and not fully captured by HEMA alone.

Analytical Chemistry, 2018 Hexavalent chromium ion (Cr6+) is one of the most toxic substances for plants, for animals, and is a confirmed human respiratory carcinogen. However, so far, there are few independent and efficient colorimetric methods for detection of Cr6+.

Advanced Science, EarlyView.An amalgamated lithium metal method enables systematic control of Sn–Cu active‐site dimensions from isolated atoms to nanocrystallites. Increasing the metal loading shifts CO2 electroreduction selectivity from acetaldehyde on highly dispersed Sn–Cu sites to formate on Sn‐rich crystallites, revealing how bimetallic dispersion and local coordination ...

British Educational Research Journal, EarlyView.Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

Advancing Theory and Practice Concerning CO2e Emissions: A Time‐Based Tool for Organisations
Business Strategy and the Environment, EarlyView.ABSTRACT Although organisations are increasingly scrutinised on their CO2e emissions, economic growth is frequently encouraged. Eco‐efficiency–based initiatives—‘doing more with less’—could be a solution. The problem is that many organisations (e.g., smaller enterprises without access to specialist knowledge) have difficulties in gauging the impact of ...
