Tenofovir Containing Thiolated Chitosan Core/Shell Nanofibers: In Vitro and in Vivo Evaluations. In addition, the ethanol vapor and the ethanol droplets from capillary were added, respectively, to the absorption system [24]. Vaporization of ethanol would be easier in the interface between the TEG-solution thin films and non-wetted packing surface, that is, the rate of vaporization of ethanol for the thinner liquid film would be larger than the thicker liquid film. According to surface thermodynamics, surface tension is defined as the Gibbs free energy required for an increase of unit surface area at constant temperature, pressure and composition, i.e. Journal of Petroleum Science and Engineering.

Badun. n Salla Hiltunen, Isto Heiskanen, Kaj Backfolk. Zhiqiang Chen, Shuqian Xia and Peisheng Ma. The experimental results showed that the effect of surface additives on surface tension was larger for adding in the gas phase than in the liquid phase. The small disturbance analysis was adopted to deduce that the surface tension gradient resulted from the change of temperature, which was large enough to produce the cellular-type flow in the liquid convective cell that was heated from the bottom [4]. According to these points of view and the experimental results, the removal amount of H2O by the TEG solution decreased with the larger air flow rate. For packed-bed absorber, the effective interfacial area is increased for the positive Marangoni effect. Ana Gayol, Lidia M. Casás, Alfonsina E. Andreatta, Raquel E. Martini, and José L. Legido . The results showed that the effective area was larger for the positive system than that of the negative system due to the more stable liquid film. Based on the thickness of the liquid layer, the Marangoni number was also calculated to assess the critical point for the interfacial disturbance resulting from the spreading liquid. Surface Tension of o-Xylene + Acetic Acid and m-Xylene + Acetic Acid Binary Mixtures from 303.15 K to 343.15 K. Karla Granados and, Jesús Gracia-Fadrique, , Alfredo Amigo and. The concentration of the TEG solution was measured by a refractometer. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. Mechanism of Charging and Supercharging Molecules in Electrospray Ionization. The present investigation was undertaken to probe the dependency of the acetic acid→acetone conversion on the redox behavior and acid–base properties of sites exposed on metal oxide surfaces. The surface tensions for absorption solutions could be measured by a surface tension meter (CBVP-A3, Kyowa Interface Co. Ltd.). The surface tension of liquid mixtures is an important physical property in heat and mass transfer at an interface. Measured surface tension and interface tension values of common articles of everyday use,surface tension, interfacial tension, interface tension, A collocation method for surface tension calculations with the density gradient theory. The working electrodes were set in the experimental cell to detect the potential energy [2]. Except for bubble absorber [9, 10], a continuous liquid phase was presented as a solution film in the mass transfer equipment for all others. Ethanol molecules would vaporize from the TEG thin film in the packed-bed absorber. Alicia García-Abuín, Diego Gómez-Díaz, José M. Navaza and Isabel Vidal-Tato. On the other hand, the larger liquid flow rate would promote the phenomenon of surface renewal. Industrial & Engineering Chemistry Research. The results showed that absorption of CO2 was enhanced by the interfacial disturbance. Viktor Kuznetsov, Alexander Akentiev, Viktor Rakhimov. Since the explanations of the effect of operating variables on mass transfer performance for TEG solution with surfactants were similar as that for the TEG solution without surfactants, the descriptions for the mass transfer performance affected by operating variables were neglected under the condition of adding surfactants.

Model for the Surface Tension of Dilute and Concentrated Binary Aqueous Mixtures as a Function of Composition and Temperature. cis L. Palaniappan, S. Nithiyanantham, S. Murugesan. The induced flowing disturbance will lead to an increment of mass transfer rate for a gas-liquid contact system. The vapor pressure of desiccant solution was lower for the lower liquid temperature, and the depression of water vapor pressure would be larger for the lower liquid temperature.

Available from: Advances in Modelling and Experimental Study for Industrial Applications, Advances in Microfluidic Technologies for Energy and Environmental Applications, Solution film in the mass transfer equipment, Surface tension of solution is suddenly dropped when the surfactant is added, Surface tension gradient was resulted in the presence of surface active substances, The area for the surface of packing material covered by TEG solution was greater for the higher concentration, Reduction in the surface tension of the solvent by adding glycine, Marangoni instability caused by the temperature dependence of the surface tension, Effective interfacial area affected by channel angle, The smaller packing and the lower liquid flow rates promote the surface refreshment, Methanol/water, methanol/isopropanol and water/acetic acid, The effective interfacial area is the same for the positive and neutral Marangoni systems at low vapor rates, Methanol-water, methanol-2-propanol and n-heptane-toluene, Froth stabilization in positives systems resulted in the increased interfacial area, The positive Marangoni effect causes stable film on the packing, Surface tension of LiBr was decreased by adding 2-ethyl-1-hexanol (2EH), Uneven distribution of surface tension at interface was induced by 2EH, Cellular convection was provoked by minute changes in surface tension, Cellular convection was observed by adsorption of CO, The Marangoni convection was induced by additive and hindered by surfactant, The interfacial disturbance was induced by adding ethanol, Department of Fashion Styling and Design, Chungyu University of Film and Arts, Taiwan, ROC, Department of Chemical Engineering, Chung Yuan Christian University, Taiwan, ROC. Journal of Analytical Atomic Spectrometry. Not only was the relationship between mass transfer process and interfacial phenomena described but also the enhancement of mass transfer performance for the absorption system was demonstrated in this study. In addition to the packed distillation column, the interfacial area for the positive system in a tray distillation column also increased with the stabilized froth [17]. For more data or any further information please search the DDB or contact DDBST. Generally speaking, the surface additive with lower surface tension was injected by a capillary tube into the center of the absorption cell. Find more information on the Altmetric Attention Score and how the score is calculated. The liquid film, flowed on the packing, contacted the gas phase in the packed-bed absorber and absorbed water vapor successfully. Foley, Muhammad A. Zenaidee, Rico F. Tabor, Junming Ho, Jonathon E. Beves, William A. Donald. Since the induced Marangoni convection and Marangoni instability were microscopic phenomena, they could be recorded or observed by scientific or special apparatus. Table 1. Effect of air flow rate on removal amount. As mentioned by Wu [11], the Marangoni effect could be triggered in mass transfer systems with continuous liquid phases.
