Oxidative damage induced by extracts of condensate, particulate matters and semivolatile organic compounds from gasoline engine exhausts were investigated in testicles of adult Sprague-Dawley rats. The results showed that gasoline engine exhaust could increase the contents of malondialdehyde and carbonyl protein, decrease activities of superoxide dismutase and glutathione peroxidase, and induce DNA damage in testicle of rat. Taking together, the gasoline engine exhaust could promote oxidative damage of bio-macromolecular in testicles of rat and oxidative stress might be an alternative mechanism for male reproductive function of male mammals.

This study investigates the HO and CO sorption behavior of two chemically distinct polystyrene-divinylbenzene-based ion exchange sorbents: a primary amine and a permanently charged strong base quaternary ammonium (QA) group with (bi)carbonate counter anions. We compare their distinct interactions with HO and CO through simultaneous thermal gravimetric, calorimetric, gas analysis, and molecular modeling approaches to evaluate their performance for dilute CO separations like direct air capture. Thermal and hybrid (heat + low-temperature hydration) desorption experiments demonstrate that the QA-based sorbent binds both water and CO more strongly than the amine counterparts but undergoes degradation at moderate temperatures, limiting its compatibility with thermal swing regeneration.

Plant biomass has emerged as a cornerstone of the global bioenergy landscape because of its abundance and cost-effectiveness. The cell wall of plant biomass is an intricate network of cellulose, hemicellulose, and lignin. The hydrolysis of cellulose and hemicellulose by holoenzymes converts these polymers into monosaccharides and paves the way for the production of bioethanol and other bio-based products.

Developing low-temperature gas sensors for parts per billion-level acetone detection in breath analysis remains challenging for non-invasive diabetes monitoring. We implement dual-defect engineering via one-pot synthesis of Al-doped WO nanorod arrays, establishing a W-O-Al catalytic mechanism. Al doping induces lattice strain to boost oxygen vacancy density by 31.

Sea surface temperature of the Red Sea has increased by up to 0.45 °C per decade over the last 30 years, and coral bleaching events are becoming more frequent. A reef bleaching event was observed in October 2020, whereby some parts of the Red Sea experienced more than 12 °C-weeks.

The study of the self-assembly of surfactants in aqueous solutions, though a traditional field, remains fascinating and full of novelty. In this article, the anionic perfluorodecanoic acid surfactant (PFA) is separately complexed with three hydroxyalkylamines (monoethanolamine (MEA), diethylamine (DEA), and triethanolamine (TEA)) in aqueous solutions. The transformation of aggregate morphologies from spherical unilamellar to nanotubes and then to spherical bilamellar is observed at room temperature, which is confirmed by cryo-transmission electron microscopy (cryo-TEM).
