Summary: This study fabricates nitrogen-doped porous carbon coembedded with lanthanum and cobalt (La-Co@NPC) as a dual-functional catalyst for sulfite oxidation and arsenic removal in the desulfurization process. The La-Co@NPC/S(IV) catalytic system generates strongly oxidizing free radicals for sulfite oxidation and oxidizes As(III) into As(V). The results show high efficiency in ammonium sulfite oxidation and arsenic removal, making it significant for the high-value recovery of sulfur resources in coal-fired desulfurization.

Summary: This study proposes a waste control method to treat wastewater containing highly toxic Cr(VI) and sulfite. Through the redox reaction of Cr(VI)-sulfite, highly toxic Cr(VI) is converted into non-toxic substances and enriched on a novel biochar-induced cobalt-based silica composite. This method effectively reduces the harm to aquatic life and human health.

Summary: This study focuses on the pollution problem of low-content SO(2) in the non-ferrous metal production industry, specifically investigating the oxidation kinetics of zinc sulfite in the zinc oxide desulfurization process. The results indicate that the oxidation process is primarily controlled by diffusion and is not significantly affected by the temperature. The presence of different crystal water in the raw material has little effect on the oxidation kinetics of zinc sulfite.

Summary: The catalysts using cobalt ferrite (CoxFe(3-x)O(4)) and sphere mesoporous silica (MCM-41) nanoparticles as support were found to enhance the oxidation rate of MgSO3 under moderate temperatures. The combination of electric field and CoFe2O4/MCM-41 showed a synergistic effect, significantly increasing the oxidation rate of MgSO3 compared to when only one factor was present. The study also revealed the mechanism of the catalytic oxidation of MgSO3, involving the reduction of oxidation potential and increased electron transfer rate.

Summary: The oxidation kinetics of zinc sulfite in the zinc-based wet flue gas desulfurization process are studied through varying parameters such as zinc sulfite concentration, initial pH, oxygen partial pressure, temperature, stirring speed, gas flow rate, and particle size. The results show that the oxidation rate is influenced by zinc sulfite concentration, oxygen partial pressure, and critical concentration, while factors like initial pH and particle size have minimal effect. The oxidation rate increases with stirring speed, gas flow rate, and temperature, with an apparent activation energy of 15.85 kJ center dot mol-1.

Summary: This article presents an electrochemical technique that uses an electroactive tracer species to probe the rate-limiting factors of redox reactions at an electrode surface. A theoretical model is developed for the transient response in step 2, considering diffusion-limited and desorption-limited recovery of the electrode potential. The mathematical modeling shows that in a desorption-limited system, the electrode potential drifts to open circuit slowly compared to a diffusion-limited system. This technique can be used to study adsorption-desorption processes during electrochemistry.

Summary: The research aimed to develop a cheap and non-toxic electrochemical sensor for determining a target analyte and reducing electronic waste. The sensor was prepared using a graphite rod from zinc-carbon batteries and was used to detect L-tryptophan in a Britton-Robinson buffer solution. Two electrochemical methods, differential pulse voltammetry and cyclic voltammetry, were employed in the experiment. The pH value of the support solution, scan rate, and L-tryptophan concentration were found to affect the current response. The oxidation of L-tryptophan was determined to be an irreversible two-electron/two-proton reaction controlled by a mixture of adsorption and diffusion.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
