A simple and rapid GC-MS method for separation, identification and quantitative determination of combustion products of organophosphorus and chlorine pesticides viz; monocrotophos, chloropyriphos, butachlor and benzenehexachloride has been developed. The method provides a positive means of identifying organic combustion products and enables to assess not only their toxicity to human beings but also their impact on the environment. The data is useful for emergency preparations in case of fire in chemical plants and warehouses that store pesticides in large quantities.

The photoinduced reaction of [Pt(NO)] with pyridine or its derivatives (L) was found to result in the formation of [PtL](NO) salts in high yield. This transformation was successfully probed for methyl- and carboxyethyl-substituted pyridines, and the corresponding [PtL](NO) salts were isolated and fully characterized using single-crystal X-ray diffraction (SCXRD). Anation of the [Pt(py)] cationic complex with N was studied by H NMR spectroscopy in aqueous and water/dimethyl sulfoxide solutions of [Pt(py)](NO).

Practical Zn metal batteries have been hindered by several challenges, including Zn dendrite growth, undesirable side reactions, and unstable electrode/electrolyte interface. These issues are particularly more serious in low-concentration electrolytes. Herein, we design a Zn salt-mediated electrolyte with in situ ring-opening polymerization of the small molecule organic solvent.

Objectives: Characterise US residents' exposure to restrictions on sales of flavoured electronic nicotine delivery system (ENDS), cigars and menthol cigarettes across states and time, and assess correlations between these policies.
Methods: From 2022 to 2024, we compiled flavour policy locations from advocacy groups and online searches, located corresponding legal texts and reviewed these to identify policy details, including effective dates. Using census data, we calculated the proportion of state residents covered by each policy quarterly from 2009 to 2024 and estimated correlations between them and cigarette taxes.

Many approaches have been implemented in order to reduce the emissions of particular pollutants without compromising engine performance. Cotton and castor mixed seed oil was chosen for the current study due to their distinct fatty acid composition and potential as a feedstock for bio-additives. Three fuel samples-99 % diesel and 1 % blended fuel (cottonseed oil + castor seed oil), 99.

This work studies the influence of flue gas composition, its moisture and ash content, on the efficiency of a CO adsorption/desorption process to capture the CO from flue gases along with its subsequent reuse in greenhouse CO enrichment (Patent ES2514090). The influence of the inlet flow rate, moisture, and ash content were analysed. The experimental conditions were based on those that are achievable under real operating conditions, namely an inlet flow rate from 1.
