Lipid peroxidation is a major process that determines the quality of various oil samples during their use and storage, in which the primary products are hydroperoxides (HP'). HP' are very stable compounds at ambient conditions and are harmful to human health. Therefore, the evaluation of the degree of oil oxidation is an excellent tool for ensuring food safety.

This study aimed at evaluating the occurrence, antibiotic resistance, and β-lactamase production in isolates recovered from meat and meat products, as well as the incidence of antimicrobial resistance (AMR) genes in these bacterial isolates. The prevalence of was very high (75% and 50%) in street kebab and raw buffalo meat, respectively. The antibiotic resistance and susceptibility behavior showed that 82% of the isolates were resistant to β-lactam antibiotics such as aztreonam, followed by methicillin (68%), oxacillin (54%), cefepime (36%), ceftazidime (34%), cefaclor (24%), cefotaxime (22%), ertapenem (4%), meropenem and imipenem (2%).

Iodometric and iodimetric titrations represent a prevailing technique to determine the concentration of Cu ions in aqueous solutions; However, their utilization in electrochemical energy storage has been overlooked due to the poor reversibility between CuI and Cu related to the shuttling effect of I species. In this work, we developed a 4A zeolite separator capable of suppressing the free shuttling of I ions, thus achieving a record-high capacity retention of 95.7% upon 600 cycles.

Designing cost-effective and highly efficient electrocatalysts for water splitting is a significant challenge. We have systematically investigated a series of quasi-2D oxides, LaSrMnMO (M = Co, Ni, Cu, Zn), to enhance the electrocatalytic properties of the two half-reactions of water-splitting, namely oxygen and hydrogen evolution reactions (OER and HER). The four materials are isostructural, as confirmed by Rietveld refinements with X-ray diffraction.

The production of e-cigarette aerosols through vaping processes is known to cause the formation of various free radicals and reactive oxygen species (ROS). Despite the well-known oxidative potential and cytotoxicity of fresh vaping emissions, the effects of chemical aging on exhaled vaping aerosols by indoor atmospheric oxidants are yet to be elucidated. Terpenes are commonly found in e-liquids as flavor additives.
