Diffusiophoresis in suspensions of highly charged soft particles
ELECTROPHORESIS, 2022AbstractDiffusiophoresis phenomenon of aoft particles suspended in binary electrolyte solutions is explored theoretically in this study based on the spherical cell model, focusing on the chemiphoresis component in absence of diffusion potential. Both the electrostatic and hydrodynamic aspects of the boundary confinement, or steric effect, due to the ...

Charge density glass dynamics – Soft potentials and soft modes
Physica B: Condensed Matter, 2012An universal fingerprint of glasses has been found in low-temperature thermodynamic properties of charge/spin density wave (C/SDW) systems. Deviations from the well-known Debye, elastic continuum prediction for specific heat (flat Cp/T3 plot) appear as two anomalies ; the upturn below 1 K and a broad bump at T~10 K (named Boson peak in glasses).

Electrophoresis of a Charge-Regulated Soft Sphere in a Charged Cylindrical Pore
The Journal of Physical Chemistry B, 2010The boundary effect on the electrophoresis of a soft spherical particle, which comprises a rigid core and a porous layer, along the axis of a cylindrical pore is analyzed under the conditions of low surface potential and weak applied electric field. The porous layer of the particle is of charge-regulated nature where the distribution of fixed charge ...

Charge heteroaggregation between hard and soft particles
Physical Review E, 2000In this paper, the heteroaggregation of opposite sign hard and soft colloidal particles has been studied by static and dynamic light scattering. The structure of the aggregates, as well as the aggregation kinetics, have been investigated. At low electrolyte concentration, where both long-range electrostatic repulsive and attractive forces are present ...

Impact of charged soft layers on electroosmosis of Maxwell fluids in soft nanochannels
Physics of Fluids, 2023In the present paper, we theoretically study the transient electroosmotic flow of general Maxwell fluids through the polyelectrolyte grafted nanochannel with a layered distribution of charges. By applying the method of Laplace transform, we semi-analytically obtain the transient electroosmotic flow from the Cauchy momentum equation and the Maxwell ...

Diffusiophoresis of a Highly Charged Soft Particle in Electrolyte Solutions
Langmuir, 2021Diffusiophoresis of a soft particle suspended in an infinite medium of symmetric binary electrolyte solution is investigated theoretically in this study, focusing on the chemiphoresis component when there is no global diffusion potential in the bulk solution.

Electrophoresis of a charge-regulated soft sphere: Importance of effective membrane charge
Colloids and Surfaces B: Biointerfaces, 2013The importance of the effective membrane charge on the electrophoretic behavior of a soft spherical particle comprising a rigid core and a charge-regulated membrane layer, mimicking both inorganic and biological colloids, is investigated. The mobility of the particle is simulated under various conditions by varying the double layer thickness, the bulk ...

Soft charge form factor of the pion
Physical Review D, 1992We identify the source of a discrepancy between ${F}_{\ensuremath{\pi}}^{\mathrm{soft}}|\mathrm{long}$ and ${F}_{\ensuremath{\pi}}^{\mathrm{soft}}|\mathrm{trans}$ found by Isgur and Llewellyn Smith. We find that the discrepancy disappears when virtual $q\overline{q}$ pair production for longitudinal-momentum transfers is included.
