Measuring dynamic surface and interfacial tensions

Advanced Materials, 1992
The surface and interfacial tensions of pure liquids and surfacttant solutions can be measured using a variety of techniques including the drop volume method (see Figure) and the ring or plate method. The various methods are briefly discussed and an automated version of the drop volume method which reliably produces results of the highest quality ...

Effects of Pilocarpine on Ocular Tension Dynamics

American Journal of Ophthalmology, 1964
Pilocarpine has been used since 1877 in the treatment of glaucoma because of its effect in lowering intraocular pressure. How­ ever, it is only since the advent of tonography and anterior chamber perfusion tech­ niques that the mechanism of this effect has been investigated.

Dynamic interfacial tension of surfactant solutions

Advances in Colloid and Interface Science, 2017
The dynamics of surfactant interfacial layers was first discussed more than a century ago. In 1946 the most important work by Ward and Tordai was published which is still the theoretical basis of all new models to describe the time dependence of interfacial properties. In addition to the diffusion controlled adsorption mechanism, many other models have

Dynamic surface tensions and dynamic surface potentials

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract Dynamic surface properties are investigated by means of measurements of the surface potential with time. These surface potentials were measured by the principle of the vibrating plate, using a toothed wheel which rotates around an axis parallel to that of the jet.

Dynamical relaxation of the surface tension of miscible phases

Physical Review Letters, 1993
The dynamical behavior of the surface tension of two initially immiscible phases on raising the temperature to a value greater than or equal to the critical temperature is studied using analytic techniques, mean field dynamical equations, Monte Carlo simulations, and molecular dynamics simulations.

Surface Tensions: Dynamics of Stria

Computer Music Journal, 2007
John Chowning's Stria is among the most famous works in the field of digital music. Since its premiere in October 1977, it has never ceased to amaze listeners owing to its sheer originality and perfect construction. Stria is a case study for electroacoustic music analysis for at least two reasons.

Concrete in dynamic tension

2016
The fracture properties of concrete are rate dependent. In this thesis the results on tensile tests at static, moderate and high loading rate are presented. The results show the influence of the loading rate not only the tensile strength, but also on the fracture energy, stress-defromation relation and fracture parameters, like fracture lengths and ...

Dynamic Surface Tension

2019
Like how static surface tension indicates various basic properties of surfactants, dynamic surface tension is an indicator for various features of surfactants under transient and non-equilibrium conditions such as concentration dependency or detergent foaming. Such features are key factors in industrial application. For example, determining the dynamic

Dynamic analysis of tension structures

Computers & Structures, 1997
Summary: The equations of motion for curved membranes are determined via Hamilton's principle and subsequently solved by the finite element method. Initially linearized equations are determined by considering small amplitude oscillations about the position of static equilibrium.
