Thermoresponsive poly(N-vinylcaprolactam) as stationary phase for aqueous and green liquid chromatography [PDF]
, 2010 Poly(N-vinylcaprolactam) (PVCL) connected to aminopropyl silica is a new stationary phase for temperature responsive liquid chromatography (TR-LC). PVCL shows a transition from hydrophilic to hydrophobic interaction between 30 and 40 degrees C.

Соціальна культура громадян - найкращий антикризовий засіб [PDF]
, 2009 An anthracene-functionalized thermosensitive block copolymer was synthesized, which formed micelles by heating its aqueous solution above the lower critical solution temperature (LCST). The micelles were subsequently crosslinked by UV illumination at 365

Simultaneous Adsorption of Cation and Anion by Thermosensitive Hydrogels [PDF]
MATEC Web of Conferences, 2021 Simultaneous usage of cationic and anionic thermosensitive hydrogels was shown to positively contribute to adsorption of heavy metal ions. The potential capacity for recovering heavy metal ions from an aqueous solution was enhanced by incorporating ...
