Condensation Sink Efficiency of Atmospheric Particles Regulated by Their Chemical Compositions and Hygroscopicity

Abstract Condensation sink (CS) from atmospheric pre-existing particles is a crucial limiting factor for the occurrence of new particle formation (NPF). However, intense NPF events occur frequently in polluted urban areas despite high CS levels. Here, to address this discrepancy,...

Functionalized Olefin-Linked Covalent Organic Frameworks for Selective Mercury Capture and Recovery from Vinyl Chloride-Rich Gas Streams

Abstract The calcium carbide-derived acetylene hydrochlorination route for vinyl chloride monomer (VCM, C2H3Cl) production remains a major source of mercury consumption and emission owing to its reliance on HgCl2/activated carbon catalysts. Selective removal of elemental mercury...

Fatty acid cycling drives metabolic uncoupling and simultaneous nitrogen removal in a low-aeration and no-recirculation activated sludge system

Metabolic uncoupling represents a fundamental strategy for in-situ sludge reduction, yet its underlying metabolic mechanisms under low-aeration conditions remain poorly understood. Here, we investigated activated sludge performance in a reactor with a depth-to-diameter ratio of 4...

Multispectroscopic Insights into the Role of Extracellular Polymeric Substances in PFOS Adsorption and Retention onto Sewage Sludge

Per- and polyfluoroalkyl substances (PFASs) in sewage sludge have attracted increasing attention due to their persistence, bioaccumulation potential, and environmental risks. However, the molecular mechanisms by which extracellular polymeric substances (EPSs) regulate PFAS adsorp...
