ABSTRACT

A fast and precise method for detergent concentration determination is presented. (Patent applications for the method described here have been submitted (EP05011904 and US60/702,261). Depending on the interest of the scientific community, the system will be commercialized. (For further information contact Hervé-W. Rémigy at the e-mail address below.) A small droplet of the detergent solution is deposited on a piece of Parafilm M and side views are recorded by two orthogonall...

Dynamic fingerprint of inks using surface tension measurement.
Ink Maker ; A unique dynamic fingerprint of any ink formulation can be generated in terms of surface tension versus surface age, from zero time to several minutes, using a differential maximum bubble pressure technique. This allows formulators and users to characterize ink performance under all possible
Temperature Dependence of Blood Surface Tension
Physiological Research ; Summary Whole blood surface tension of 15 healthy subjects recorded by the ring method was investigated in the temperature range from 20 to 40 C. The surface tension σ as a function of temperature t (C) is described by an equation of linear regression as σ(t) = (-0.473 t + 70.105) 10^sup
DYNAMIC SURFACE TENSION and Surface Energy in Ink Formulations and Substrates.
Paint & Coatings Industry ; It is essential that ink formulators understand the principles and relationships of surface tension, and surface energy or wetting tension. They must control coating transfer and adhesion by developing formulations that perform well under widely varying application speeds and operating conditions.
Effect of shield gas composition on surface tension of steel droplets in a gas-metal-arc welding arc
Metallurgical and Materials Transactions ; A technique for in-situ measurement of the surface tension of molten steel droplets in a gas-metalarc welding plasma is described. Surface tension measurements obtained using this method are reported for ER70S-6 wire, with varying shielding gas compositions, and compared with previously reported
Dynamic surface tension measurement of water-based inks formulations, frustrations and flexibilities.
Ink & Print ; Introduction Many factors influence the successful implementation and use of water-borne ink systems in the printing process. External factors such as shipping and storage, freezing and thawing both before and after the process, are controllable to some degree. The physical properties of the
The Role of Surface Tension on the Residual Water Content of Fabrics
Journal of Surfactants and Detergents ; ABSTRACT: Cotton has been shown to hold up to 80% of its initial weight in water due to strong capillary forces after washing. According to the LaPlace equation for capillary rise, the rise is proportional to the surface tension of the air-liquid interface. The use of a tailored rinse additive has
On the Role of Surface Tension in the Pathophysiology of Emphysema
American Journal of Respiratory and Critical Care Medicine ; Pulmonary emphysema is a disease that is characterized, if not defined, by the destruction of lung parenchyma (1). This destruction is believed to result principally from the damaging effects of proteolytic enzymes and free radicals generated within the alveolar compartment in response to noxious
Surface tension and viscoelastic properties of embryonic tissues depend on the cytoskeleton. (includes panel discussion)(The Cytoskeleton: Mechanical, Physical, and Biological Interactions)
The Biological Bulletin ; A number of morphogenetic phenomena in early development, as well as in vitro experiments, suggest that embryonic tissues in many respect behave as liquids. A small chunk of such tissue, originally of arbitrary shape, will eventually assume an almost perfectly spherical shape when left alone in the
Formulation Problem Solving with Dynamic Surface Tension Measurement.
Paint & Coatings Industry ; The process of applying a fluid onto a substrate is a dynamic one w endive surfactants are used, causing surface tension to vary as the speed of the application varies. Surfactants are used to reduce surface tension in water- and solventborne formulations. Waterborne coatings, inks, and similar
Surface Tension of Polyethylene Used in Thermal Coating.
Polymer Engineering and Science ; NICOLE RAYMONDE DEMARQUETTE [1] In this work the surface tension of a polyethylene used in thermal coating, identified as a mixture of low density polyethylene (LDPE) and stearic acid, was measured as a function of temperature for temperatures ranging from 120[degrees]C to 150[degrees]C using a
