Elimination of fast variables in stochastic nonlinear kinetics
(2020-08-21)
A reduced chemical scheme involving a small number of variables is often sufficient to account for the deterministic evolution of the concentration of the main species contributing to a reaction. However, its predictions ...
Scaling of submicrometric Turing patterns in concentrated growing systems
(American Physical Society, 2018-09-18)
The wavelength of a periodic spatial structure of Turing type is an intrinsic property of the considered reaction-diffusion dynamics and we address the question of its control at the microscopic scale for given dynamical ...
Stochastic approach to Fisher and Kolmogorov, Petrovskii, and Piskunov wave fronts for species with different diffusivities in dilute and concentrated solutions
(2020-11-15)
A wave front of Fisher and Kolmogorov, Petrovskii, and Piskunov type involving two species A and B with different diffusion coefficients and is studied using a master equation approach in dilute and concentrated solutions. ...
The FKPP wave front as a sensor of perturbed diffusion in concentrated systems
(American Physical Society, 2019-02-11)
The sensitivity to perturbations of the Fisher and Kolmogorov, Petrovskii, Piskunov front is used to find a quantity revealing perturbations of diffusion in a concentrated solution of two chemical species with different ...
Assembly of Helical Structures in Systems with Competing Interactions under Cylindrical Confinement
(American Chemical Society, 2019)
The behavior under confinement of nanoparticles interacting with the short-range attraction and long-range repulsion potential is studied by means of Monte Carlo simulations in the grand canonical ensemble. The study is ...
Chemical and structural properties of reduced graphene oxide – dependence on the reducing agent
(Springer, 2020-11-09)
Graphene oxide (GO) prepared from graphite powder using a modified Hummers method and reduced graphene oxide (rGO) obtained from GO using different reductants, i.e. sodium borohydride, hydrazine, formaldehyde, sodium ...
Grooved step emulsification systems optimize the throughput of passive generation of monodisperse emulsions
(Royal Society of Chemistry, 2019-04-07)
Microfluidic step emulsification passively produces highly monodisperse droplets and can be easily parallelized for high throughput emulsion production. The two main techniques used for step emulsification are: i) edge-based ...
Investigation of Shape Transformations of Vesicles, Induced by Their Adhesion to Flat Substrates Characterized by Different Adhesion Strength
(MDPI, 2021)
The adhesion of lipid vesicles to a rigid flat surface is investigated. We examine the influence of the membrane spontaneous curvature, adhesion strength, and the reduced volume on the stability and shape transformations ...
The influence of confinement on the structure of colloidal systems with competing interactions
(Royal Society of Chemistry, 2020)
Colloidal systems with competing interactions have a complex phase diagram with several periodic microphases, in which particles are arranged in lamellae, cylinders or clusters. Using grand canonical Monte Carlo simulations, ...
Shape Transformations of Vesicles Induced by Their Adhesion to Flat Surfaces
(American Chemical Society, 2020)
The shape transformations of lipid vesicles induced by the adhesion to a flat surface is investigated. We perform the calculations within the framework of the Helfrich spontaneous curvature model. The calculations were ...
