Summary: In this study, a persulfate-enhanced electro-coagulation system (PECS) was constructed to improve the removal of COD and shorten the settling time of the flocculation precipitates. By using activated persulfate oxidation process, PECS can reduce the aromaticity and complexity of organic matter, generating small molecular-weight organic matter to alleviate the pressure of subsequent treatment of the leachate. The results suggest that PECS could improve the removal of organic matter, increase the COD removal, and shorten the separation time of precipitates under similar treatment costs to conventional processes.

Summary: The study evaluates the efficacy of four different garbage enzymes prepared from fruit peels (pineapple, banana, orange, and lemon) in removing soluble chemical oxygen demand (sCOD) from landfill leachate at two temperatures (room temperature and higher temperature). The results showed that orange (10%) and lemon (15%) garbage enzymes had the highest sCOD reduction at room temperature. The study demonstrated that the garbage enzyme could increase the bioavailability of organics in leachate.

Summary: The study demonstrated the potential of a one-stage partial nitrification-Anammox process (PNA) to effectively remove nitrogen and organics from leachate, with up to 96% of total nitrogen and 43% of COD being removed. Fluorescence analysis revealed insights into the dynamics of influent fluorophores, seasonal variations, and the preferential removal of protein-like compounds. Oxygen supply was found to promote the degradation of protein-like compounds, with potential implications for aerobic oxidation pathways. Additionally, fluorescence was suggested as a potential indicator for biodegradable organics, showing strong correlations with biodegradable chemical oxidation demand (BCOD).

Summary: Landfill waste disposal has become popular in recent decades due to its easy and cost-effective nature for managing waste. However, the heterogeneity of the waste makes it difficult to predict the fate of pollutants, making bio-monitoring and specific treatment challenging. One major issue associated with landfill treatment is leachate, which poses a greater risk of soil and groundwater pollution. The presence of diverse micropollutants in landfill leachates, including microbial pathogens, pesticides, microplastics, pharmaceuticals, and other harmful chemicals, calls for improved methods for their treatment and removal.

Summary: Landfills can lead to microplastic pollution as plastic waste degrades and releases microplastics into the surrounding environment, contaminating soil and water. This paper provides a comprehensive review of the degradation process of macroplastics into microplastics, the types of microplastics in landfill leachate, and the potential toxicity of microplastic pollution. Various treatment methods, including chemical precipitation and filtration, can effectively remove microplastics from wastewater. Continuous monitoring and effective removal of microplastics from landfill leachate are important to protect human and environmental health.

Summary: The development of new strategies to combat Gram-negative bacterial infections, particularly those resistant to antibiotics, is crucial due to the global increase in antibiotic resistance. This study focuses on the use of extracorporeal blood cleansing devices with affinity sorbents for capturing bacterial lipopolysaccharide (LPS), which stimulates an exacerbated immune response during infection. Molecular dynamics simulations were conducted to investigate the interaction mechanism between an anti-LPS factor (ALF) isoform 3 from Penaeus monodon (AL3) and lipid A (LA, a component of LPS). The results revealed the binding mechanism and key interacting residues, which can guide the design of LPS-sequestrating molecules for blood detoxification.

Summary: In response to the demand for cost-effective monitoring, glucose sensing devices have made significant progress in recent years. Enzyme-based devices face challenges such as poor stability and time-consuming purification procedures, leading to the development of enzyme-free sensors using different components. Several reviews have been published addressing sensor materials and synthesis methods, but the information has not yet translated into commercial devices. This review critically analyzes existing information on non-enzymatic glucose electrodes from an engineering perspective, linking sensitivity, stability, and response under physiological conditions to electrode characteristics.

Summary: Disinfection is commonly used in wastewater treatment plants to reduce the presence of pathogens. However, the emergence of micropollutants has become a serious concern, and it is worth investigating tertiary treatments that can remove both pathogens and micropollutants. UV-C photo-degradation processes are widely used for disinfection due to their simplicity and easy operation, and they have shown potential for the removal of contaminants. This study compared the performance of several photo-degradation technologies for the removal of two targeted micropollutants, and found that UV-C photolysis and UV-C photocatalysis were the most suitable technologies for degradation.

Summary: Difluoromethane (R-32), a hydrofluorocarbon (HFC), has been widely used as a primary component of refrigerant mixtures in refrigeration and air conditioning. The recovery of R-32 from depleted mixtures collected from end-of-life equipment is sought for synthesizing low-GWP refrigerant blends. Composite polymer/ionic liquid membranes based on poly-ether-block-amide have shown potential for separating R-32 from other fluorinated hydrocarbons. In this study, a spray coating technique was successfully applied to create defect-free thin selective layers of different coatings. The pilot results confirmed the superior performance and stability of [C2C1im] [SCN]-based membranes in recovering R-32 from refrigerant mixtures.

Summary: In this study, the design of extractive distillation (ED) processes for separating the components of the R-410A mixture was evaluated by considering the influence of mass transfer phenomena and ionic liquid (ILs) properties. The results showed that solubility selectivity was the most influential IL property, and [C2C1im][SCN] was identified as a promising entrainer due to its high solubility selectivity and low viscosity, which allowed for operation at lower temperatures. The recovered R-32 can serve as a greener alternative to high-GWP R-410A and as a main component in the formulation of new low-GWP mixtures.

Summary: This paper updates the RESNA Position on the Application of Power Wheelchairs for Pediatric Users with current and additional scientific literature. It provides clinical applications and evidence supporting the use of power mobility for young children, assisting practitioners in decision-making and justification. RESNA states that age, limited vision or cognition, behavioral issues, and the ability to walk or propel a manual wheelchair should not be used as discriminatory factors against providing power mobility for children. RESNA recommends early utilization of power mobility for children with mobility limitations to promote integration, development, independence, and participation.

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.
