Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Raman spectroscopic study of the vivianite arsenate minerals

, 2003
The molecular structures of the vivianite-type arsenate minerals were studied using a combination of Raman and infrared spectroscopy. The Raman spectra of the hydroxyl-stretching regions are complex with overlapping bands at 3419, 3209, 3185 and 3010 cm ...

On the Effect of Pore Shape and Size on the Auxetic Properties of Perforated Sheets Based on the ‘Rotating Squares’ Model

physica status solidi (b), Volume 263, Issue 5, May 2026.
The auxetic system with diamond‐shaped voids reproducing the classic ‘rotating‐square’ auxetic system is re‐investigated and optimised via the incorporation of additional triangular voids at the edges of each diamond perforation. The resulting systems are better suited for applications requiring lightweight design or where specific pore geometries are ...

Arsenic accumulation by the aquatic fern Azolla: Comparison of arsenate uptake, speciation and efflux by A. caroliniana and A. filiculoides

, 2008
This study investigates As accumulation and tolerance of the aquatic fern Azolla. Fifty strains of Azolla showed a large variation in As accumulation. The highest- and lowest-accumulating ferns among the 50 strains were chosen for further investigations.

Nitric oxide alleviated arsenic toxicity by modulation of antioxidants and thiol metabolism in rice (Oryza sativa L.).

Frontiers in Plant Science, 2016
Nitric oxide is a gaseous signalling molecule and has a profound impact on plant growth and development. It is reported to serve as pro oxidant as well as antioxidant in plant system.

Can Coastal Rowing Be Made Safer Through Auxetics‐Inspired Personal Protective Equipment?

physica status solidi (b), Volume 263, Issue 5, May 2026.
A survey of beach sprint coastal rowers examined perceived injury risk, attitudes towards personal protective equipment (PPE) and barriers to its use. The findings were used to guide the design of auxetic‐based PPE for this sport that is highly conforming, breathable and visually appealing. We report the results of a survey aimed at assessing how beach
