Critical Fluctuations in Polymer Solutions: Crossover from Criticality to Tricriticality
Mikhail A. Anisimov, Thomas J. Longo, Jan V. Sengers
Critical fluctuations in fluids and fluid mixtures yield a nonanalytic asymptotic Ising-like critical thermodynamic behavior in terms of power laws with universal exponents. In pol…
Thermodynamic Modeling of Fluid Polyamorphism in Hydrogen at Extreme Conditions
Nathaniel R. Fried, Thomas J. Longo, Mikhail A. Anisimov
Fluid polyamorphism, the existence of multiple amorphous fluid states in a single-component system, has been observed or predicted in a variety of substances. A remarkable example…
Modeling Fluid Polyamorphism Through a Maximum-Valence Approach
Nikolay A. Shumovskyi, Thomas J. Longo, Sergey V. Buldyrev +1
We suggest a simple model to describe polyamorphism in single-component fluids using a maximum-valence approach. The model contains three types of interactions: i) atoms attract ea…
Physical origin of the expansion of polymer coils in a binary solvent in the vicinity of its demixing critical point
Jan V. Sengers, Mikhail A. Anisimov, Xiong Zheng
Critical fluctuations are known to induce a collapse of polymer chains in a mixed solvent upon approaching its liquid-liquid critical point, as originally predicted by Brochard and…
Unusual transformation of polymer coils in a mixed solvent close to the critical point
Xiong Zheng, Mikhail A. Anisimov, Jan V. Sengers +1
We have discovered unusual behavior of polymer coils in a binary solvent (nitroethane+isooctane) near the critical temperature of demixing. The exceptionally close refractive indic…
Mesoscale solubilization and critical phenomena in binary and quasi binary solutions of hydrotropes
Andreas E. Robertson, Dung H. Phan, Joseph E. Macaluso +5
Hydrotropes are substances consisting of amphiphilic molecules that are too small to self assemble in equilibrium structures in aqueous solutions, but can form dynamic molecular cl…
