Highly Selective Arsenite Sensor Based on Gold Nanoparticles and Ionic Liquids

Chemosensors, 2023
Here, we report a highly selective arsenite (As(III)) sensor based on gold nanoparticles (AuNPs) and ionic liquids (ILs). AuNPs were citrate-capped with negative charges on their surfaces, and could aggregate and precipitate once electrolytes were ...

Das ungewöhnliche [B(ReO4)4]−‐Anion in der nicht‐zentrosymmetrischen Kristallstruktur von K[B(ReO4)4]

Angewandte Chemie, EarlyView.
Farblose Kristalle von K[B(ReO4)4] wurden durch die Reaktion von KReO4 mit B2O3 in einer Re2O7 Schmelze erhalten. Die Einkristallstrukturanalyse zeigt B(ReO4)4]−‐ Anionen, die durch vier [ReO4]‐Tetraeder, die an ein zentrales Boratom koordinieren, aufgebaut ist.

The Elusive [B(ReO4)4]− Anion in the Non‐Centrosymmetric Crystal Structure of K[B(ReO4)4]

Angewandte Chemie International Edition, EarlyView.
Colorless crystals of K[B(ReO4)4] have been obtained from the reaction of KReO4 with B2O3 in a melt of Re2O7. According to single‐crystal structure analysis the compound has an anion which is built up by four (ReO4)‐tetrahedra coordinated to a central boron atom. Furthermore, the compound has been investigated by Raman spectroscopy and DFT calculations

Influence of silicon on arsenic uptake and toxicity in lettuce

Journal of Applied Botany and Food Quality, 2015
Lettuce grown in soil is found to contain high concentrations of arsenic (As). This paper investigates the uptake and speciation of As in lettuce as well as the influenceof silicon (Si) on As uptake, since Si may decrease it.

Critical mineral removal from mining‐impacted waters using microalgal biomass

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large
