Life at ultralow interfacial tension: wetting, waves and droplets in demixed colloid-polymer mixtures
Mixtures of colloids and polymers display a rich phase behavior, involving colloidal gas (rich in polymer, poor in colloid), colloidal liquid (poor in polymer, rich in colloid) and colloidal crystal phases (poor in polymer, highly ordered colloids). Recently, the colloidal gas-colloidal liquid interface received considerable attention as well. Due to the colloidal length scale the interfacial t...
متن کاملDynamic Analysis of Moving Cables with Variable Tension and Variable Speed
Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...
متن کاملInterfacial Tension of Electrolyte Solutions
A theory is presented to account for the increase in surface tension of water in the presence of electrolyte. Unlike the original “grandcanonical” calculation of Onsager and Samaras, which relied on the Gibbs adsorption isotherm and lead to a result which could only be expressed as an infinite series, our approach is “canonical” and produces an analytic formula for the excess surface tension. F...
متن کاملFluctuation-induced dynamics of multiphase liquid jets with ultra-low interfacial tension.
Control of fluid dynamics at the micrometer scale is essential to emulsion science and materials design, which is ubiquitous in everyday life and is frequently encountered in industrial applications. Most studies on multiphase flow focus on oil-water systems with substantial interfacial tension. Advances in microfluidics have enabled the study of multiphase flow with more complex dynamics. Here...
متن کاملEquilibria for anisotropic surface energies with wetting and line tension
We study the stability of surfaces trapped between two parallel planes with free boundary on these planes. The energy functional consists of anisotropic surface energy, wetting energy, and line tension. Equilibrium surfaces are surfaces with constant anisotropic mean curvature. We study the case where the Wulff shape is of a special type of “product form”, that is, its horizontal sections are a...
