Analytical modeling of micelle growth. 4. Molecular thermodynamics of wormlike micelles from ionic surfactants: theory vs. experiment
K. D. Danov, P. A. Kralchevsky, R. D. Stanimirova +3
Hypotheses: The aggregation number and length of spherocylindrical (rodlike, wormlike) micelles in solutions of an ionic surfactant and salt can be predicted knowing the molecular…
Analytical modeling of micelle growth. 3. Electrostatic free energy of ionic wormlike micelles -- effects of activity coefficients and spatially confined electric double layers
K. D. Danov, P. A. Kralchevsky, S. D. Stoyanov +2
Hypotheses: To correctly predict the aggregation number and size of wormlike micelles from ionic surfactants, the molecular-thermodynamic theory has to calculate the free energy pe…
Rheology of protein-stabilised emulsion gels envisioned as composite networks. 1 -- Comparison of pure droplet gels and protein gels
Marion Roullet, Paul S. Clegg, William J. Frith
Protein-stabilised emulsion gels can be studied in the theoretical framework of colloidal gels, because both protein assemblies and droplets may be considered as soft colloids. The…
Viscosity of protein-stabilised emulsions: contributions of components and development of a semi-predictive model
Marion Roullet, Paul S. Clegg, William J. Frith
Protein-stabilised emulsions can be seen as mixtures of unadsorbed proteins and of protein-stabilised droplets. To identify the contributions of these two components to the overall…
Why clothes don't fall apart: tension transmission in staple yarns
Patrick B. Warren, Robin C. Ball, Raymond E. Goldstein
The problem of how staple yarns transmit tension is addressed within abstract models in which the Amontons-Coulomb friction laws yield a linear programming (LP) problem for the ten…
DNA-coated Functional Oil Droplets
Alessio Caciagli, Mykolas Zupkauskas, Aviad Levin +6
Many industrial soft materials often include oil-in-water (O/W) emulsions at the core of their formulations. By using tuneable interface stabilizing agents, such emulsions can self…
Diffusiophoresis in non-adsorbing polymer solutions: the Asakura-Oosawa model and stratification in drying films
Richard P. Sear, Patrick B. Warren
A colloidal particle placed in an inhomogeneous solution of smaller non-adsorbing polymers will move towards regions of lower polymer concentration, in order to reduce the free ene…
Dissipative particle dynamics: systematic parametrization using water-octanol partition coefficients
Richard L. Anderson, David J. Bray, Andrea S. Ferrante +3
We present a systematic, top-down, thermodynamic parametrization scheme for dissipative particle dynamics (DPD) using water-octanol partition coefficients, supplemented by water-oc…
The flow and evolution of ice-sucrose crystal mushes
Andrew Gilbert, Felix Oppong, Robert Farr
We study the rheology of suspensions of ice crystals at moderate to high volume fractions in a sucrose solution in which they are partially soluble; a model system for a wide class…
Sliding friction in the hydrodynamic lubrication regime for a power-law fluid
Patrick B. Warren
A scaling analysis is undertaken for the load balance in sliding friction in the hydrodynamic lubrication regime, with a particular emphasis on power-law shear-thinning typical of…
Screening properties of four mesoscale smoothed charge models, with application to dissipative particle dynamics
Patrick B. Warren, Andrey Vlasov
We extend our previous study [J. Chem. Phys. 138, 204907 (2013)] to quantify the screening properties of four mesoscale smoothed charge models used in dissipative particle dynamics…
Lamellar and inverse micellar structures of skin lipids: Effect of templating
Chinmay Das, Massimo G. Noro, Peter D. Olmsted
The outermost layer of skin, the stratum corneum (SC), comprises rigid corneocytes in a layered lipid matrix. Using atomistic simulations we find that the equilibrium phase of the…
Screening properties of Gaussian electrolyte models, with application to dissipative particle dynamics
Patrick B. Warren, Andrey Vlasov, Lucian Anton +1
We investigate the screening properties of Gaussian charge models of electrolyte solutions by analysing the asymptotic behaviour of the pair distribution functions. We use a combin…
Self-consistent field theory for the interactions between keratin intermediate filaments
Anna Akinshina, Etienne Jambon-Puillet, Patrick B. Warren +1
We have developed a model for the interactions between keratin intermediate filaments based on self-consistent field theory. The intermediate filaments are represented by charged s…
How to impose stick boundary conditions in coarse-grained hydrodynamics of Brownian colloids and semi-flexible fiber rheology
Robert D. Groot
Long-range hydrodynamics between colloidal particles or fibers is modelled by the Fluid Particle Model. Two methods are considered to impose the fluid boundary conditions at colloi…
Controlling the self-assembly of binary copolymer mixtures in solution through molecular architecture
M. J. Greenall, P. Schuetz, S. Furzeland +4
We present a combined experimental and theoretical study on the role of copolymer architecture in the self-assembly of binary PEO-PCL mixtures in water-THF, and show that altering…
Phase Phenomena in Supported Lipid Films under Varying Electric Potential
Andrey V. Brukhno, Anna Akinshina, Zachary Coldrick +2
We model cyclic voltammetry experiments on supported lipid films where a non-trivial dependence of the capacitance on the applied voltage is observed. Previously, based on a mean-f…
Ultra-long range correlations of the dynamics of jammed soft matter
Simona Maccarrone, Giovanni Brambilla, Olivier Pravaz +8
We use Photon Correlation Imaging, a recently introduced space-resolved dynamic light scattering method, to investigate the spatial correlation of the dynamics of a variety of jamm…
Water permeation through stratum corneum lipid bilayers from atomistic simulations
Chinmay Das, Peter D. Olmsted, Massimo G. Noro
Stratum corneum, the outermost layer of skin, consists of keratin filled rigid non-viable corneocyte cells surrounded by multilayers of lipids. The lipid layer is responsible for t…
Simulation studies of stratum corneum lipid mixtures
Chinmay Das, Massimo G. Noro, Peter D. Olmsted
We present atomistic molecular dynamics results for fully hydrated bilayers composed of ceramide NS-24:0, free fatty acid 24:0 and cholesterol, to address the effect of the differe…
Jamming in sheared foams and emulsions, explained by critical instability of the films between neighboring bubbles and drops
N. D. Denkov, S. Tcholakova, K. Golemanov +1
Phenomenon of foam and emulsion jamming at low shear rates is explained by considering the dynamics of thinning in the transient film, formed between the neighboring bubbles and dr…
Scaling theory for diffusion limited cluster aggregation in a porous medium
Patrick B. Warren
A scaling theory is developed for diffusion-limited cluster aggregation in a porous medium, where the primary particles and clusters stick irreversibly to the walls of the pore spa…
