Summary: The study found that zero valent iron can degrade nitrobenzene through both reduction and advanced oxidation under oxygen-limited conditions. The contribution of center dot OH to the degradation of nitrobenzene increases with time, with reduction remaining the main pathway of transformation. The balance between ZVI, dissolved oxygen, and iron-complexing ligands is crucial for the optimal removal of organic contaminants.

Summary: The study found that a dual-layer Pt-Pd/Al2O3 washcoated monolith promoted by an Al2O3-supported Mn0.5Fe2.5O4 spinel base layer can effectively increase methane and NO conversions, with the O-2 storage and release property of the spinel being necessary to fully exploit the modulation enhancement. The addition of spinel moves the balance between metallic and oxidic precious metal crystallites closer to the theoretical neutral point, leading to higher oxidation efficiency and lower byproduct NH3 selectivity.

Summary: LowCat is a catalytic material that catalyzes CO oxidation and NOx reduction simultaneously, with effectiveness at low temperatures. By transforming the goethite component to hematite, it increases catalytic activity and forms a critical surface-bound oxygen intermediate for NO2 reduction. LowCat demonstrates significant performance under conditions relevant to automotive and diesel combustion systems, particularly in reducing NO2 to N2 at low temperatures.

Summary: Four different boron and cerium doped TiO2 photocatalysts were synthesized by the EDTA-citrate method and studied for degradation of two common fluoroquinolone-based antibiotics under sunlight. The synthesized catalysts showed 90-93% degradation for both antibiotics and demonstrated stability up to three consecutive runs, with e- and OH identified as the dominant species responsible for the photocatalytic activity. These catalysts also showed efficient disinfection capabilities against E.coli under solar light.

Summary: The issue of catalyst deactivation due to alkali poisoning remains a challenge for NOx reduction by NH3. A novel strategy of modifying Fe2O3/TiO2 catalysts with phosphate has been demonstrated to enhance NOx reduction in the presence of alkaline metals, by creating alkali-poisoning sites, increasing surface acidity, enhancing redox ability, and protecting active sites from alkali poisoning. This approach shows promise in providing inspiration for designing catalysts with exceptional resistance to alkaline metals for controlling NOx emissions.

Summary: The UK Department of Transport conducted a vehicle emissions testing programme in 2016 in response to the Volkswagen emissions scandal. The programme revealed significant discrepancies between real-world and in-lab testing of diesel passenger vehicles. Findings include mismanaged exhaust gas recirculation altering NOx emissions, the introduction of a new Real-Life Emissions methodology, and a concerning divergence between NOx improvement and CO2 deterioration. These findings contribute to improving vehicle emissions testing, developing climate change mitigation strategies, and enhancing air quality.

Summary: Blood derivatives are commonly used in metabolomic clinical studies due to their low invasiveness and rich biological information. However, the choice of blood collection tubes can affect the metabolic content of plasma and serum. In this study, the metabolomic and lipoprotein profiles of blood samples collected using different tubes were compared. Results showed significant alterations in metabolites and correlations among the three blood matrices. The influence of blood collection tubes on lipoprotein profiles was also observed but to a lesser extent. Overcoming the issue of different collection tubes is crucial for scaling metabolomics and lipoprotein analysis in epidemiological studies. A statistical solution based on regression was proposed to reduce the alterations induced by different collection tubes for both metabolomic and lipoprotein profiles.

Summary: Marble is prone to copper leaching, resulting in visible turquoise stains. Therefore, conservators search for cleaning materials specific to the structure to avoid damaging the surface. Agar and EDTA have been extensively studied, but microbiological growth and material damage are drawbacks. To address these issues, natural materials like kudzu and konjac gels combined with chelating agents such as citrate, oxalate, and gluconic acid were investigated. Various analytical techniques were used to characterize copper cleaning. Konjac and kudzu showed promise as alternatives to agar with simplified preparation and antimicrobial properties. EDTA was found to be the most harmful, while citrate and gluconic acid emerged as potential substitutes with comparable or superior cleaning capabilities without negative side effects.

Summary: A series of iron-niobium composite oxides prepared with the assistance of CTAB exhibited superior SCR performance, with strong interaction between Fe and Nb promoting the formation of gamma-Fe2O3 and enhancing reducibility of iron at low temperatures. This resulted in higher surface acidity and more active sites on the catalyst, leading to increased NOx conversion during the NH3-SCR reaction.

Summary: An axial traction strategy was developed to optimize the electronic structure of the M-N-4 moiety, leading to atomically dispersed nickel sites coordinated with four nitrogen atoms and one axial oxygen atom embedded within the carbon matrix (Ni-N-4-O/C). This Ni-N-4-O/C electrocatalyst exhibited excellent CO2RR performance with a high CO Faradic efficiency close to 100% at -0.9 V, maintaining the CO FE above 90% in a wide potential window. The superior CO2RR activity is attributed to the axial traction effect induced by the Ni-N-4-O active moiety.

Summary: Blended amine solvents, comprising N,N-dimethylcyclohexylamine (DMCA) and N-methylcyclohexyamine (MCA), showed rapid absorption rate, large CO2 capacity, and efficient regeneration for CO2 capture. The total mass transfer coefficient of CO2 in DMCA-MCA was higher than that of 5 M MEA, and the total regeneration energy of DMCA-MCA blend was significantly lower than 5 M MEA. This novel solvent could be a potential alternative for CO2 capture.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
