Structural and dynamic properties of colloids near jamming transition

Sol/gel transition of oil/water microemulsions controlled by surface grafted triblock copolymer dodecyl–PEO227–dodecyl: molecular dynamics simulations with experimentally validated interaction potential

“…This change in the g(r) curves can be explained by the fact that the low volume fraction microemulsions lost their uid characters and form gel structures. As observed in similar published studies, [52][53][54] the critical temperature, corresponding to the loss of the sol state characteristics, shows a pronounced increase with increasing F,…”

Static and dynamic properties of decane/water microemulsions stabilized by cetylpyridinium chloride cationic surfactant and octanol cosurfactant

“…The present ndings in terms of g(r) and S(q) are in good agreement with the results of other experimental and numerical approaches for similar colloidal systems. [11][12][13][39][40][41] The results presented in Table 2 indicate that the pressure and the potential energy increase monotonically with increasing F, and the osmotic compressibility decreases with increasing F. where m stands for the mass of the microemulsion, v(t) stands for its velocity, z stands for the friction coefficient, and F s (t) represents a random force. The friction coefficient z is related to the microemulsion viscosity, h, and the microemulsion radius, R, by the classical Stokes relation z ¼ 6phR.…”

“…From a mesoscopic point of view, much effort has been dedicated to the development and parameterization of effective interaction potentials to study the structure and dynamics of colloidal systems. [11][12][13] This is supposed to save extensive details and yield valuable information. Thus, the physical properties, in terms of the micro arrangements and collective dynamics of colloidal systems, are determined by considering the colloids as dispersed particles interacting via an effective interaction.…”

Liquid, glass, gel: The phases of colloidal Laponite

“…Kumar and Wu [33] reported molecular dynamics simulations of colloids interacting through a short-ranged van der Waals attraction and a longer-ranged electrostatic repulsion. They observed a variety of 'jammed states' at volume fractions between / = 0.4 and / = 0.1, ranging from nearly uniform glass-like structures to network-like gel structures.…”
