Dynamic surface tension of xylem sap lipids

Tree Physiology, 2020
AbstractThe surface tension of xylem sap has been traditionally assumed to be close to that of the pure water because decreasing surface tension is thought to increase vulnerability to air seeding and embolism. However, xylem sap contains insoluble lipid-based surfactants, which also coat vessel and pit membrane surfaces, where gas bubbles can enter ...

Effects of Dynamic Surface Tension on Droplet Formation of Surfactant Solution Injected from a Capillary Tube

Journal of Fluid Science and Technology, 2010
Effects of dynamic surface tension on the droplet formation of surfactant solutions were studied. Test fluids used were aqueous solutions of CTAB at several surfactant mol concentrations (CD) and CTAB/NaSal aqueous solutions at CD=1.0 mM and at three mol

Evaluation of surface activity of rhamnolipid biosurfactants produced from rice bran oil through dynamic surface tension

Journal of Petroleum Exploration and Production Technology, 2023
The use of low-cost carbon substrates such as agricultural residues can drastically lower the cost of biosurfactant production. In this study, rice bran oil extracted from agricultural waste was used as a renewable carbon source for biosurfactant ...

Surface tension implementation for Gensmac 2D [PDF]

, 2001
In the present work we describe a method which allows the incorporation of surface tension into the GENSMAC2D code. This is achieved on two scales. First on the scale of a cell, the surface tension effects are incorporated into the free surface boundary ...

Surface tension fluctuations and a new spinodal point in glass-forming liquids [PDF]

, 2009
The dramatic slowdown of glass-forming liquids has been variously linked to increasing dynamic and static correlation lengths. Yet, empirical evidence is insufficient to decide among competing theories.

Surface tension of steel at high temperatures

SN Applied Sciences, 2023
Surface tension is a material property that is needed to describe fluid behaviour, which impacts industrial processes, in which molten material is created, such as thermal cutting, welding and Additive Manufacturing.

Influence of graphene nano-platelets dispersion on the thermo-physical properties of sunflower oil [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2022
In this article, thermal stability, viscosity, density and surface tension of graphene nano-platelet dispersed in sunflower oil are experimentally determined by varying the graphene concentration (0.1-1.1 wt.%) and temperature (40-100°C).

Dynamic renormalization group study of a generalized continuum model of crystalline surfaces [PDF]

, 2001
We apply the Nozieres-Gallet dynamic renormalization group (RG) scheme to a continuum equilibrium model of a d-dimensional surface relaxing by linear surface tension and linear surface diffusion, and which is subject to a lattice potential favoring ...
