A process is provided for the production of a surface coating as well as the use of surface coatings to increase the surface tension of objects. The surface coating is obtained by depositing a layer of at least one element that can be oxidized with water or an alloy that can be oxidized...
IN 1900, Bénard 1 described his observations of a cellular deformation produced on the free surface of a liquid film the bottom surface of which (in contact with a floor) was uniformly heated and hotter than its top surface. He also observed a cellular flow associated with the deformation. ...
In addition, the temperature coefficient −(dγ/dT) of the surface tension of the binder melt was changed. In the case of two additives, the surface tension of the powder coating and its temperature coefficient were lowered considerably. This effect of additives is desirable to reach good ...
Derive a relation between surface tension and surface energy. What is the cause of surface tension? Explain 2 factors that affect surface tension. Explain how is surface tension related to surface energy. What is the use of surface tension? What do you understand by the term surface tens...
Surface tensionis a physical property equal to the amount of force per unit area necessary to expand the surface of aliquid. It is the tendency of a fluid surface to occupy the smallest possible surface area. Surface tension is a principal factorin capillary action. The addition of substan...
aWith the same concentration, the product’s surface tension is reduced while increase the oleoyl chloride usage, accordingly, the foam height is also increased (the results are shown in Figure5). 正在翻译,请等待... [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语...
The encapsulation occurred during SMSI can be considered as a wetting process of the Au NPs by reduced titanium oxide (TiO2−x). As reported by Fu et al.18, the encapsulation process is mainly determined by the surface tensions. According to surface tension balance Eq. (1), a larger surf...
Bidirectional Control of Flow in Thin Polymer Films by Photochemically Manipulating Surface Tension To this end, we describe here a photopolymer whose melt-state surface tension can be selectively raised or lowered in light exposed regions depending on the wavelength and dose of applied light. The ...
摘要: Surface tension in the static condition and the temperature coefficient of surface tension were determined in the temperature range from the vicinity of liquidus temperature to 1873 K.DOI: 10.2320/jinstmet1952.45.2_147 被引量: 6 年份: 1981 ...
Residual trapping means that CO2 is stuck in the pores of the rock, and cannot flow even if there is an opening, because of the surface tension between CO2 and water. Chemical trapping Chemical trapping occurs when CO2 is absorbed onto organic matter present in coal and shale (adsorption trap...
