Bai et al. report a novel fluorescent styrylpyridinium-based probe that exhibits strong coordination and highly selectivity toward Zn2+ ions in aqueous solution with low detection limit at room temperature for metal ion detection. Read the article: doi.org/10.1071/CH23... #AusJChem

A novel ratiometric fluorescent sensor based on terpyridine derivatives for Zn2+ in aqueous solution

We designed and synthesized a new fluorescent probe G based on 4-bromobenzaldehyde, CH3I and 4-vinylpyridine. Probe G formed a 1 : 1 complex with Zn2+ that

(1/2) Manesha Fernando & al. explore the applicability of recycled carbon fibres as structural composites and for energy storage (free standing anodes for Li-ion batteries) when modified with bis-aryldiazomethine. They determined that this modification improved flexural modulus and

(1/2) Colette A. Geier et al. developed a safe, low-cost antioxidant assay technique which uses readily available materials. The method is based on the blue colouration of a starch-Betadine (a povidone–iodine complex) solution and demonstrates quantitative agreement with conventional assay methods.

Blue Betadine assay: a safe, low-cost test for antioxidant activity

Antioxidants, such as those in customarily used plants, are vital to health and nutrition, but testing them often requires expensive or hazardous chemicals

In this paper Siyao Qiu & al. present a DFT study of the hydrogen evolution mechanism for the widely studied [FeFe]-hydrogenases-inspired molecular catalysts. They also investigate the effect different ligands have on the hydrogen evolution reaction. #AusJChem Details: connectsci.au/ch/article/7...

(1/4) Mahinga kai (food gathering) is still practised in the Te Arawa Rotorua Lakes of Aotearoa New Zealand. However, biophysical characteristics and geothermal influences in these lakes result in high concentrations of heavy metals (As, Cd, Cu, Fe, Pb, Mn, Hg and Zn).

Heavy metal concentrations in the tissues of kākahi, Echyridella menziesii (Gray, 1843), and water from wadable depths in Lake Tarawera, Aotearoa–New Zealand

This study identified that concentrations of heavy metals vary spatially within Lake Tarawera, with greater concentrations in areas of higher water flow, p
