In this study we use state of the art x-ray scattering and molecular dynamics structural probes to carry out a careful analysis of amine-water mixtures that show the unusual lower critical solution temperature (LCST) behavior. The goal is to provide direct experimental evidence for the entropy-lowering molecular cluster formation originally ...

Development of hybrid diblock copolypeptide amphiphile/magnetic metal complexes and their spin crossover with lower-critical-solution-temperature(LCST)-type transition [PDF]
Abstract Diblock copolypeptide amphiphiles have been attracting much interest as motifs for self-assembly in the production of nanostructures such as nanoparticles, nanosheets, and nanofibers. In this study, we first focus on the self-assembly of magnetic metal complexes in water using diblock copolypeptides. In addition, not only were nanocomposites

Unique LCST phase behaviour of imidazolium-based ionic liquids is reported, which can be controlled by concentration, the choice of cation, anion and solvent, and by supramolecular complex formation. MD simulations provide insight into the molecular basis of this LCST phenomenon.

A thermodynamic analysis of LCST mixtures reveals important relationships and application-specific property targets. While LCST phase separation is always endothermic, LCST behavior can emerge even when the entropy of mixing is positive.

Machine learning to determine optimal conditions for controlling the size of elastin-based particles
This paper evaluates the aggregation behavior of a potential drug and gene delivery system that combines branched polyethyleneimine (PEI), a positively-charged polyelectrolyte, and elastin-like polypeptide (ELP), a recombinant polymer that exhibits lower

Constrained thermoresponsive polymers – new insights into fundamentals and applications
In the last decades, numerous stimuli-responsive polymers have been developed and investigated regarding their switching properties. In particular, thermoresponsive polymers, which form a miscibility gap with the ambient solvent with a lower or upper ...
