The final bouncing surface had much different surface tension, she said, and she sank into it.
But oil has much lower surface tension than water does, so it has a greater tendency to spread over and cling to surfaces.
Hierarchical structure composed of nanorod arrays and microflowers was formed on the copper surface by an alkali assistant oxidation process; after fluorination, the surface became super-repellent toward water and several organic liquids possessing much lower surface tension than that of water, such as hexadecane.
Oil-proof technology is harder to achieve as oil has a much lower surface tension than water, so it spreads out easier and thus is harder to get rid off.
In contrast, DEPN-8+1.5% Mini-B reached much lower surface tensions of 43.7±0.8 mN/m and 38.1±0.7 mN/m after 1 and 20 min of adsorption, respectively.
The incorporation of SDS, AOS, APG or LAB into 2- 4- 3,3,4,4,5,5,5-heptafluoro-2,2-bis trifluoromethyl pentyl benzamido -N,N-dimethylethana-mine oxide 4a could generate much lower CMC and surface tension value at the CMC than individual 4a.
In species with larger spores, like T. caries (Fig. 1a), the merger of Buller's drop with a prominent adaxial drop is associated with a much greater change in surface tension that powers the longer flight of the spore.
This dispersion has much higher equilibrium and dynamic surface tension than those before freezing.
Bubbles and droplets, which depend upon a perfect balance between internal and external air pressure to maintain their surface tension, bear much of the emblematic weight, appearing literally in a fountain or a stream of piss, or as metaphors for physical experience: "My body's / a drop of water", "the soap film is my skin".
We have developed a new method for the estimation of critical micelle concentrations (cmcs) that is suitable for use at high temperatures and pressures; is much more rapid than the surface tension method; and is applicable to a wide range of surfactant classes, including both ionic and amphoteric (zwitterionic) surfactants.
