Surface Tension profiles in vertical soap films
Physical Review E, 2015Co-Authors: Nicolas Adami, Herve CapsAbstract:: Surface Tension profiles in vertical soap films are experimentally investigated. Measurements are performed by introducing deformable elastic objets in the films. The shape adopted by those objects once set in the film is related to the Surface Tension value at a given vertical position by numerically solving the adapted elasticity equations. We show that the observed dependency of the Surface Tension versus the vertical position is predicted by simple modeling that takes into account the mechanical equilibrium of the films coupled to previous thickness measurements.

Experimental and theoretical investigation on Nano-fluid Surface Tension
Journal of Natural Gas Science and Engineering, 2015Co-Authors: Hemat Ranjbar, Amir Safiri, Samaneh Bovard, Mohammad Reza Khosravi-nikou, Ali KhazaeiAbstract:Abstract Effect of γ-Al 2 O 3 and MgO nanoparticle on Surface Tension of Tri Ethylene Glycol (TEG) was studied for different nanoparticle concentrations. Furthermore, the effect of nanoparticle size on the Nano-fluid Surface Tension was investigated. Results showed that Surface Tension increases for some particle concentrations and decreases for some others; in other words, a certain particle concentration could not be determined as the boundary for the increase or decrease of Surface Tension. Moreover, Sorbitan oleate was added to TEG solution to investigate the changes in Surface Tension that may occur due to the addition of surfactants. It is shown that by increasing surfactant concentration, Nano-fluid Surface Tension would decrease. The effect of nanoparticle size on Surface Tension was analyzed as well. Using experimental data, five empirical and thermodynamic-based models; i.e., Redlich–Kister (RK), Malanovsky-Marsh (MM), Jufu et al. (JBZ), Chunxi et al. (CWZ) and Santos et al. (SFF) were evaluated for Surface Tension estimation, and it was found that SFF method is the best method to correlate nano fluid Surface Tension in this study.

Vibration based on liquid Surface Tension
Applied Physics Letters, 2011Co-Authors: Xing Yang, Dan Li, Jia Rui Yang, Zhaoying Zhou, Quan Shui ZhengAbstract:In this paper, vibration based on liquid Surface Tension is reported. A prototype vibrator composed of a water film sandwiched between two plates is fabricated and tested. The free and the continuous vibrations (electromagnetic drive) of the proposed vibrator are demonstrated. The mechanical model of the vibrator is also presented. Theoretical analysis and experiments prove the Surface Tension, which has the advantages of the no-mechanical parts, simple-structure, and self-lubrication, is effective for driving. The liquid Surface Tension vibrator demonstrates the potential applications in resonating sensors, precision actuator, and mechanical switch.
