Summary: Artificial photocatalysis is a promising method for selective conversion of CH4 to CH3OH, but the over-oxidization by active oxygen radicals hinders its efficiency. In this study, a strategy of transferring key intermediates for stability was proposed. A Co3O4/ZnO composite photocatalyst effectively converted CH4 to CH3OH under simulated sunlight irradiation, while pure ZnO only over-oxidized CH4 into CO2. Co(3)O(4) was found to play a crucial role in adsorbing .CH3 key intermediates and desorbing CH3OH to suppress CH4 over-oxidation on the ZnO surface.

Summary: A TiO2/ZnO bilayer thin film was prepared using magnetron sputtering and thermal oxidation. The oxidation temperature was found to affect the structural, optical, photocatalytic, photostability, and antimicrobial properties of the film. Increasing the oxidation temperature led to the transformation of Ti0.895O.77 into the anatase/rutile TiO2 phase and improved the crystallinity of TiO2. The resulting Ti/ZnO thin film exhibited excellent photocatalytic performance and antimicrobial properties when thermally oxidized at 550°C.

Summary: A new photocatalytic methodology was developed for the depolymerization of oxidized Kraft lignin to industrially relevant aromatic platform chemicals. The process involves oxidation of alcohol moieties using a gold nanoparticle/hydrotalcite composite, followed by UVA irradiation with TiO2 to decrease the molecular weight of lignin. Characterization of the products confirmed the depolymerization of lignin to smaller molecular weight products. This method offers both energetic and chemical advantages over thermochemical processing for lignin valorisation.

Summary: The degradation of the emerging pollutant fluoxetine (FLX) and the formation of potentially present by-products were investigated through photocatalytic processes using modified TiO2. The photocatalysts showed the ability to produce hydroxyl radicals (& BULL;OH) and achieved 100% degradation of RhB under UV or visible irradiation. LC-MS-Q-TOF analysis confirmed an alternative mechanism for FLX degradation mediated by one of the by-products. Other by-products were also identified after photodegradation, indicating their presence in FLX-contaminated ecosystems cannot be ignored. Therefore, the high-performance photocatalysts obtained in this study are viable alternatives for the remediation of organic pollutants in aquatic ecosystems.

Summary: The study evaluated the degradation and transformation of four phenylurea herbicides into NDMA under three oxidation conditions. Results showed that the efficiency of oxidants in degrading PUHs varied, with ozone being the fastest and chlorine the slowest. NDMA formation potential was significantly promoted by ozonation compared to chloramination alone, with different molar yields for each PUH. Additionally, the degradation kinetics data agreed with the pseudo-first-order model, and the reaction mechanisms revealed several pathways for NDMA formation from DMA and phenylamino-compounds during oxidation processes.

Summary: The use of biostimulants, such as oligosaccharins, can improve tomato yield under stress conditions without negatively impacting the environment. Applying oligosaccharins to the roots decreases the concentration of certain compounds in the fruit, while applying them via the leaves does not have this effect. The stimulatory effect of oligosaccharins on yield is more evident under lower temperature-stress.

Summary: This study focuses on the detoxification of aqueous waste solutions polluted with emerging pharmaceuticals and pesticides using a coupled biological-photocatalytic facility under natural sunlight. The results showed that pharmaceutical residues were effectively removed during the biological treatment process, while the biodegradation of pesticides was less effective. However, all compounds were rapidly degraded during the photocatalytic treatment process. Solar heterogeneous photocatalysis could be a promising technology for tertiary treatment in wastewater treatment plants, particularly in arid areas with water scarcity and ample sunlight.

Summary: This manuscript presents the results of a bibliometric analysis conducted on the Dithiocarbamate Fungicides (DTFs) and food research area using the Web of Science database. A total of 374 publications were examined, with the majority of scientific production occurring between 2012 and 2021, but showing a 32% decline in the last two years. The Journal of Agricultural and Food Chemistry, India, and Sardar Vallabhbhai National Institute of Technology were identified as the most productive journal, country, and institution, respectively. The study also highlights the decreasing trend in the Reference Publication Year Spectroscopy index and suggests focusing on individual DTFs, metabolites, and a change in analysis methodology for future research.

Summary: This paper reviews the impact of different stages of beer-making on the behavior of pesticide residues. The use of pesticides on barley and hop can result in the presence of pesticide residues in beer. Factors such as pH, temperature, water content, and physical-chemical properties of pesticides play important roles in determining the fate of residues. Most pesticides show a decrease in concentration during the brewing process, but maltsters should pay attention to hydrophobic pesticides while brewers should control hydrophilic pesticides to maintain the quality and organoleptic properties of beer.

Summary: The presence of emerging micropollutants in the environment has become a significant threat to human health and aquatic ecosystems. These micropollutants, including pharmaceuticals and pesticides, enter the environment through human activities and can be found in various water sources. Conventional wastewater treatment plants are not effective in removing a large portion of these pollutants, particularly pharmaceuticals, leading to continuous contamination of freshwater systems. In this study, the effectiveness of TiO2 as a photocatalyst combined with Na2S2O8 as an oxidant was evaluated for the treatment of wastewater effluent contaminated with pharmaceutical residues. The results showed that this solar heterogeneous photocatalysis method significantly enhanced the removal of pharmaceuticals from the wastewater effluent. However, the presence of dissolved salts and organic carbon in the wastewater effluent slowed down the degradation process. The study also found that macrolides had the longest degradation time in wastewater effluent compared to other compounds studied. This methodology is particularly relevant in water-scarce areas with abundant sunlight, such as the southeast of Spain.

Summary: This paper reviews the impact of different stages in beer-making process (malting, mashing, boiling, and fermentation) on the behavior of pesticide residues in beer. The factors affecting residue stability and the physical-chemical properties of pesticides are crucial in determining their fate. Pesticide concentrations decrease during the beer-making process, but different attention should be given to hydrophobic residues in malt and hydrophilic residues in young beer to ensure beer quality.

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.

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.
