Molecular insight into the lower critical solution temperature transition of aqueous alkyl phosphonium benzene sulfonates

Communications Chemistry, 2019
Ionic liquid (IL)-water mixtures can exhibit a lower critical solution temperature (LCST) transition, but changes in long-range order and local molecular environment during this transition are not comprehensively understood.

Responsive glyco-poly(2-oxazoline)s: synthesis, cloud point tuning, and lectin binding [PDF]

, 2011
A new sugar-substituted 2-oxazoline monomer was prepared using the copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction. Its copolymerization with 2-ethyl-2-oxazoline as well as 2-(dec-9-enyl)-2-oxazoline, yielding well-defined copolymers with ...

A route to explain water anomalies from results on an aqueous solution of salt

, 2010
In this paper we investigate the possibility to detect the hypothesized liquid-liquid critical point of water in supercooled aqueous solutions of salts. Molecular dynamics computer simulations are conducted on bulk TIP4P water and on an aqueous solution ...

Holographic superconductors in quintessence AdS black hole

, 2013
We present a solution of Einstein equations describing a $d$-dimensional planar quintessence AdS black hole which depends on the state parameter $w_q$ of quintessence. We investigate holographic superconductors in this background and probe effects of the

Recognition-mediated hydrogel swelling controlled by interaction with a negative thermoresponsive LCST polymer [PDF]

, 2016
Most polymeric thermoresponsive hydrogels contract upon heating beyond the lower critical solution temperature (LCST) of the polymers used. Herein, we report a supramolecular hydrogel system that shows the opposite temperature dependence.
