Surface tension

View this topic in
Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example, in floating of some objects on the surface of water, even though they are denser than water, and in the ability of some insects and even reptiles to run on the water surface. This property is caused by cohesion of like molecules, and is responsible for many of the behaviors of liquids. (Wikipedia.org)

  • Dynamics Study on Soft Matter Drop by Ultrasound

    In this paper, the motion equation of the bubble radius in the incompatible liquid under the action of ultrasound is derived from the studying of cavitation bubble motion, which provides foundation for the study of the change of the radius of the bubble under the action of ultrasound. The influence of ultrasonic frequency, amplitude of ultrasonic, initial radius and interfacial tension on the change of bubble radius are discussed by using the MATLAB methods.The results show that the smaller of frequency or the higher of ultrasonic pressure magnitude, the movement of droplets is more intense. If ultrasonic pressure magnitude is smaller than the static pressure, the drop will do micro steady vibration at the initial radius. In the case of the initial radius is smaller, the movement of the droplet is more intense, but has very little influence on the last radius of drop. The size of interfacial tension coefficient has little effect on the change droplet radius in ultrasonic field.

  • Influence of bulk surfactant transport on airway reopening

    During pulmonary airway reopening, a finger of air creates an interface that is continually expanding into a surfactant filled fluid. The quantity of surfactant transported to this interface affects the local surface tension, /spl gamma/, and thus the reopening pressure. The goal of this study is to demonstrate how transport barriers can affect the mechanics of this system. We use a combined boundary integral and finite difference technique to solve the governing equations in an axisymmetric geometry. When the quantity of surfactant in the fluid is low, a bulk diffusion barrier exists such that C/sub s/<C/sub 0/, where C/sub s/ is the concentration near the interface and C/sub 0/ is the upstream concentration. Under these conditions, reopening pressures are elevated since /spl gamma/>/spl gamma//sub eq/, the equilibrium surface tension.

  • Generation of Water Droplet in Fluorocarbon Using Electrostatic Atomization

    Droplet-based micro-reactor systems have been investigated by many researchers and used in bioengineering and micro total analytical systems (μTAS). In these applications, individual water droplets in oil perform as micro-reactors. Generally, a magnetic stirrer and a homogenizer have been used to produce water droplets in oil. For these studies, fluorocarbon oil is an attractive candidate for the droplet-based system because of its very low solubility in water, and very low solubility of water in them. However, it is more difficult to generate W/F (water-in-fluorocarbon oil ) emulsion for a reason of the stability of fluorocarbon oils compare with other common oils. Here we conducted W/F droplet formation using the electrostatic method. Electrostatic atomization was used to produce charged water droplets into fluorocarbon oil. Our method can control the size of water droplets by adjusting the applied DC voltage. The generated water droplets were stable without a surfactant due to electrical charge. Moreover, the generated droplets kept their shape and position until fluorocarbon oil evaporated. Therefore, W/F emulsion was highly expected for an application in micro total analytical systems.

  • The effect of atmospheric contaminants on the electrical properties of plasma-deposited hydrogenated amorphous silicon for use in photovoltaic cells

    Current measurements were begun on fresh samples within 1.5 h after removal from the plasma generator. These invariably showed a transient which decayed, over a period of a day, to a steady state, as seen in Figure 1. On short circuiting, the current measured was zero. On reapplication of the bias, the current which flowed was transientless and of the same magnitude as the previous steady-state current.

  • A new method of measuring blood viscosity with a U-shaped scanning capillary-tube viscometer using a Casson model

    The present study introduces a method to consider different surface tensions at two riser tubes for the viscosity measurements of fluids using a U-shaped scanning capillary-tube viscometer (SCTV). The accuracy and repeatability of the SCTV were demonstrated by comparing the viscosity results of distilled water obtained from the SCTV with the well-accepted reference data for water. Non-Newtonian viscosity of fresh human blood was measured at a body temperature of 37/spl deg/C. The results demonstrate that whole blood viscosity can be measured over a range of shear rates in less than 2-3 min without any anticoagulants using disposable U-shaped capillary-tube sets.

  • Lead-Free Soldering Technology Review - Evaluating Solder Pastes and Stencils

    Lead-free solders differ from lead-bearing solders in several properties such as surface tension, wetting ability, etc. In paste form they have greater adhesion force, so they can block small stencil apertures more easily. Because of this fact, the printing parameters and stencils design criterias have to be changed. Since lead-free soldering has to be implemented in the electronic industry until 1<sup>st</sup> of July 2006, selection of the appropriate pastes and stencils is more important than ever. In our experiment six TSC (Tin-Silver-Copper) solders from different suppliers were evaluated from aspects of wetting properties, solderability and printability alike. Component self alignment was also investigated. In addition three kinds of stencils (lasercut stainless steel, lasercut nickel and electroformed nickel) were investigated as well by measuring transfer efficiency in function of area ratio of stencil-apertures. Results have shown that electroform stencils have outstanding printing properties while lasercut stencils (stainless steel and nickel) have similar capabilities independently of the material, thus it is not sure it is worth using lasercut nickel stencils for double the price. The evaluation of solders has revealed that the new lead-free pastes have equally excellent printing and soldering properties. Lead-free soldering with these pastes will not be problem.

  • Defect control of immersion lithography with top coat material

    193nm immersion lithography is the most promising lithography candidate toward 45nm node technology and beyond; because it is able to obtain larger DOF and higher resolution at a hyper NA lens design greater then 1.0. Also the recent progress of 193nm immersion lithography technology would be applicable to establish the high volume manufacturing process soon. However, immersion specific issue, such as the immersion specific defect (Gil et al., 2005) and the leaching of resists compound into immersion fluid (Tsuji et al., 2005), still exists without any effective countermeasure. In order to prevent these immersion specific criteria, topcoat is one of the most useful materials. In this report, we discuss the top coat development criteria that are the suppression ability for leaching material, the protection capability for water penetration, surface tension control and so on.

  • New technology for recording the information based on intramolecular bonds in water

    A new technology for recording information based on the discreet spectrum of the intramolecular bond energies in water is described. For the latter the existence of a space net of bonded with H-bonds molecules with approximate tetrahedral symmetry is supposed. The discrete character of the water energy spectrum is proved by the measurement of the surface tension variations of evaporating water drops. Using the Shannon's formula, a new term information spectrum of water is introduced, in which the information related to one pair of water molecules as a function of the discrete values of the intramolecular bond energies is represented. The experimental results showing why this information spectrum as a method registered the weak physical and chemical influences on the water are represented.
