Upper critical solution temperature (UCST)-type thermoresponsive polymers from hydrogen-bonding monomers

open access: yes, 2018
UCST-type thermoresponsive polymers (i.e. that phase separate from solution upon cooling) present a tremendous potential not only in aqueous media where they can be used in drug delivery, diagnostic and microfluidic applications, but also in water ...

Dual-functional ionic liquids exhibiting upper critical solution temperature behavior and antibacterial activity as draw solutes for forward osmosis

open access: yesChemical Engineering Journal Advances
Eight ionic liquids (ILs) were systematically synthesized by pairing alkylammonium-based cations—dodecyltrimethylammonium ([N11112]+) and octyltrimethylammonium ([N1118]+)—with fluorinated anions, including trifluoromethanesulfonate ([OTf ...

Topology‐Encoded Charge Polarity Governs Multiphase Organization in Intrinsically Disordered Protein Polymer Condensates

open access: yesSmall, Volume 22, Issue 52, 16 September 2026.
Electrostatic topology is shown to program phase separation and internal organization in thermoresponsive intrinsically disordered protein polymer (IDPP) condensates. By comparing oppositely charged IDPPs with a covalent diblock, chain connectivity is revealed to control charge compensation, dense‐phase micropolarity, miscibility, and apparent acid ...
