The locomotion of droplets in emulsions is practical significance for fields related to medicine and chemical engineering, which can be done with a magnetic field move containing materials. Here, we demonstrate new method droplet the oil-in-water emulsion help nonuniform case where nanoparticles (MNPs) are dispersed continuous phase emulsion. paper analyses motion liquid film capillary various diameters droplets, their number density, viscosity It established that mechanism largely depends...
In this paper we investigate the linear stability and properties, such as speed, of planar travelling combustion front. The speed front is estimated both analytically, using matched asymptotic expansion, numerically, by means shooting relaxation methods. Evans function approach extended compound matrix method employed to numerically solve problem for wave solution.
Micromotors are fascinating objects that able to move autonomously and perform various complex tasks related drug delivery, chemical processes, environmental remediation. Among the types of micromotors, droplet-based micromotors characterized by a wide range functional properties capability encapsulation deformation possibility using them as microreactors. Relevant problems micromotor utilization in processes include intensification mixing locomotion passive objects. In this paper, technique...
Magnetic motors can transform the energy of an external magnetic field into kinetic their motion. When moving collectively in a microchannel, interact not only with each other but also channel walls, which leads to wide variety motion modes. In our work, collective Fe3O4 nanomotors different fluids microchannel non-uniform is studied. During process motion, induce flow surrounding liquid and move together convective flow. Due deceleration at wall, velocity depends on height. case gradient...
Active matter contains self-propelled units able to convert stored or ambient free energy into motion. Such systems demonstrate amazing features related the phenomenon of self-organization and phase transitions can be used for development artificial materials machines that operate away from equilibrium. Significant advances in fabrication active were achieved when studying low-density gas small crystallites. However, technique preparation matter, where one observe formation stable crystals,...
The propagation of planar combustion waves in an adiabatic model with two-step chain-branching reaction mechanism is investigated. travelling wave becomes unstable respect to pulsating perturbations as the critical parameter values for Hopf bifurcation are crossed space. demonstrated be a supercritical nature and it gives rise periodic neutral stability boundary crossed. increase ambient temperature found have stabilizing effect on waves. However, does not qualitatively change behaviour...
We consider travelling wave solutions of a reaction–diffusion system corresponding to single-step homogeneous premixed combustion scheme competitively coupled with an endothermic reaction. Properties the reaction fronts, such as speed and burnt temperature are derived numerically over range different parameter values, those describing relative enthalpies, rates activation energies exothermic reactions. Unique shown exist for each distinct combination values. Stability analyses using both...
In this paper we investigate the linear stability and properties of planar travelling non–adiabatic combustion front for cases zero non–zero ambient temperature. The speed is estimated numerically using shooting relaxation methods. It shown that given parameter values solution either does not exist or there are two solutions with different speed, which referred to as 'fast' 'slow'. Evans function approach extended by compound–matrix method employed solve linear–stability problem...

The wide research interest in nano-, micro-, and macromotors is due to the diverse range of applied problems engineering, biomedicine, ecology. At same time, amount known mechanisms responsible for locomotion motors limited. Here, we demonstrate a novel method motor locomotion, which can be contingently called "chemical magnetism". phenomenon considered here based on fact that any current loop magnetic field affected by force. "Chemical magnet" represents bimetal surfer swimming at...
A mathematical model of infiltrative tumour growth is investigated taking into account transitions between two possible states malignant cells: proliferation and migration. These are considered to depend on oxygen level in a threshold manner where high concentration allows cell proliferation, while below certain critical value induces The spreading rate dependence parameters obtained. It shown that the depends tissue manner.
