Effects of gamma radiation on two aromatic polysulfones [PDF]
, 1975 Two aromatic polysulfones, poly(oxy‐1,4‐phenylenesulfonyl‐1,4‐phenyleneoxy‐1,4‐phenyleneisopropylidene‐1,4‐phenylene) (I) and poly (oxy‐1,4‐phenylenesulfonyl‐1,4‐phenylene) (II), undergo crosslinking and chain scission at 30°C during γ‐irradiation, the ...

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Water reclamation in the textile industry is essential to reduce environmental impacts associated with high water consumption and pollutant discharge. Among emerging technologies, pervaporation (PV) has gained attention due to its high selectivity and efficiency in contaminant removal. However, there is still a lack of comprehensive

Polysulfones grafted with poly(vinylphosphonic acid) for highly proton conducting fuel cell membranes in the hydrated and nominally dry state [PDF]
, 2008 Mechanically strong and flexible membranes with very high local concentrations of immobilized proton-conducting phosphonic acid have been achieved by grafting poly(vinylphosphonic acid) side chains onto polysulfones. The graft copolymers were prepared by

Porous Organic Cages for CO2 Capture and Confined Reduction
Angewandte Chemie, Volume 138, Issue 28, 6 July 2026.Porous organic cages (POCs) enable the coupling of CO2 capture and conversion through the interplay of molecular structure and solid‐state organization. Beyond intrinsic cavities, packing‐dependent pore accessibility and mass transport govern local CO2 concentration and catalytic performance, linking adsorption to reactivity in integrated capture ...

Aromatic polysulfones containing functional groups by synthesis and chemical modification [PDF]
, 1987 Aromatic polysulfones containing functional groups were prepared by two synthetic approaches: by copolymerization of a carboxyl containing bisphenol monomer, or by chemical modification of polysulfones.

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

A molecular dynamics simulation study of three polysulfones in dry and hydrated states [PDF]
, 2010 International audienceMolecular dynamics (MD) simulations of three polysulfones (poly(ether sulfone) PESU, poly(phenylene sulfone) PPSU and polysulfone PSU) in dry and hydrated states were undertaken in order to study the specific interactions between ...

Small, EarlyView.An in situ fabricated porous organic cage membranes (PCM) exhibits reversible solvent pore switching property in response to water and methanol. Water stimulated structural rearrangement enables selective removal of Rh B and heavy metal ions (Ni2+ and Zn2+), whereas methanol stimulates the pore expansion promotes Ni2+ and Zn2+ ions recovery.
