Summary: Propylene, a crucial component for producing industrial chemicals like polypropylene, is difficult to separate from propane due to their similar physical properties. The separation process mainly relies on energy-intensive distillation processes and accounts for a significant portion of global energy consumption. However, a copper complex supported by a fluorinated bis(pyrazolyl)borate has shown promising results in achieving selective separation of propylene from propane under mild conditions.

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: Salinity gradient energy, especially using reverse electrodialysis (RED) technology, has attracted attention as a renewable energy source. However, the influence of divalent ions on the technology's performance has not been extensively studied. This study focuses on estimating the resistance of RED membranes in water flows containing divalent ions, both theoretically and experimentally. Results show that calcium and magnesium ions have a greater impact on energy generation compared to sulfate.

Summary: This study assesses the scale-up of reverse electrodialysis (RED) for the harvesting of renewable salinity gradient energy (SGE) in two selected coastal wastewater treatment plants in Europe. The research utilizes an optimization model to quantify the net present value (NPV), and finds that the industrial scale-up of SGE-RED is feasible in Ierapetra, Greece, due to higher flow rates and temperature. However, in Comillas, Spain, it could be cost-competitive with conventional alternatives under certain conditions.

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.
