Article Abstract
A diisocyanate-bridged polyethylene glycol modification and time-controlled amidoximation strategies are developed to engineer UiO-66 metal-organic frameworks (MOFs), achieving 115.3% and 130.0% CO/N adsorption selectivity enhancements escalated CO-MOF interactions. This universal approach could be accommodated in diverse MOF systems for tailored carbon capture and separation applications.

The Role of the Environment (Water, Air, Soil) in the Emergence and Dissemination of Antimicrobial Resistance: A One Health Perspective.

Antimicrobial resistance (AMR) has emerged as a planetary health emergency, driven not only by the clinical misuse of antibiotics but also by diverse environmental dissemination pathways. This review critically examines the role of environmental compartments-water, soil, and air-as dynamic reservoirs and transmission routes for antibiotic-resistant bacteria (ARB) and resistance genes (ARGs). Recent metagenomic, epidemiological, and mechanistic evidence demonstrates that anthropogenic pressures-including pharmaceutical effluents, agricultural runoff, untreated sewage, and airborne emissions-amplify resistance evolution and interspecies gene transfer via horizontal gene transfer mechanisms, biofilms, and mobile genetic elements.

The application of animal manure to agricultural soil is a very common practice to improve soils fertility, providing a rich source of organic matter and nutrients. However, the presence of certain trace elements in the manure can result in a threat for food safety and the environment. In addition to their potential toxic effects on crops, animal and humans, certain metals such as cadmium, chromium, copper, nickel, mercury, cobalt, lead and zinc may play a role in the emergence and spread of antibiotic resistance, as they can increase the selective pressure on bacteria.

The scope of this work was to develop a thin-film composite (TFC) membrane for the separation of CO/CO mixtures, which are relevant for many processes of gas processing and gasification of carbon-based feedstock. Special attention was given to the development of highly permeable porous polysulfone (PSF) supports (more than 26,000 GPU for CO) since both the selective and support layers contribute significantly to the overall performance of the TFC membrane. The PSF porous support is widely used in commercial and lab-scale TFC membranes, and its porous structure and other exploitation parameters are set during the non-solvent-induced phase separation (NIPS) process.

The proliferation of pathogenic bacteria and antibiotic resistance genes (ARGs) in the biofilm of drinking water distribution pipes poses a serious threat to human health. This work adopted 15 polyethylene (PE) pipes to study the co-selective effect of dissolved organic matter (DOM) and chlorine on the bacterial community and their antibiotic resistance in biofilm. The results indicated that ozone and granular activated carbon (O-GAC) filtration effectively removed lignins and proteins from DOM, and chlorine disinfection eliminated carbohydrate and unsaturated hydrocarbons, which both contributed to the inhibition of bacterial growth and biofilm formation.

Article Synopsis
- Optimizing the binding energy at active sites is essential for improving the selectivity and activity of catalysts in the electrochemical reduction of CO2. !* -
- Copper is effective in reducing CO to hydrocarbons but struggles with product selectivity due to moderate binding energies of intermediates; a new Cu-Pd dimer structure is proposed using a metal-organic framework (MOF) to address this issue. !* -
- The incorporation of palladium into the Cu-Pd structure enhances the adsorption of the COOH* intermediate, leading to more selective generation of carbon monoxide and deepening the understanding of catalyst structure-activity relationships. !*
