The interaction between two spheres in a solution of nonadsorbing polymers, with excluded volume interaction, is calculated from the depletion layers around the spheres using the generalized Gibbs adsorption equation. By combining the bulk correlation length with the curvature-dependent interfacial tension between a sphere and the surrounding polymer solution [Hanke, Eisenriegler, and Dietrich,...

In this paper we analyze the effects of the following phenomena associated with the thermocapillary migration of a drop. The first is the influence of Newtonian surface rheology of the interface and the second is that of the energy changes associated with stretching and shrinkage of the interfacial area elements, when the drop is in motion. The former occurs because of dissipative processes in ...

The actual mechanisms occurring at interfaces underlying the Dzyaloshinskii-Moriya interaction (DMI) remain a question in nanomagnetism. In this study, we investigate origin of interfacial DMI, aiming estimating how independent DMI contributions two FM layer are and what their relative weight effective amplitude is. To aim, explore correlation between metal properties, namely, atomic number, el...

This article shows that in a van der Waals multiferroic heterostructure, the electric field controls polarization and influences interfacial Dzyaloshinskii-Moriya interaction, resulting creation annihilation of skyrmions.

this study focuses on the preparation and modification of a thin-film composite (tfc) hollow fiber polyamide membrane fabricated by the interfacial polymerization of piperazine (pip) and trimesoyl chloride (tmc) on a porous polysulfone substrate. the effects of triethylenetetramine (teta) and silica nanoparticles (sio2) contents in the aqueous phase (as the additives) on the morphology and perf...

in this paper, a simplified formulation for compositional reservoir simulator is presented. these types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. the procedure for solving compositional model equations is completely described. for equilibrium calculation, property estimation peng robinson equation of state is used. this equation was ...

Monitoring the quality of frying oil is important for the health of consumers. This paper reports a microfluidic technique for rapidly quantifying the degradation of frying oil. The microfluidic device generates monodispersed water-in-oil droplets and exploits viscosity and interfacial tension changes of frying oil samples over their frying/degradation process. The measured parameters were corr...
