A basic research study for improvement of plasma-sprayed zirconia coatings has been conducted. The contact angle and surface tension of the molten manganese/zirconia-yttria ceramic system were measured at 1573 K by the sessile drop method, suggesting that molten manganese would spontaneously infiltrate open pores in zirconia coatings. Structure and elementary composition development of zirconia ceramics caused by reaction with manganese were examined by using scanning electron microscopy (SEM...

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.
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
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
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
