Contact-angle-hysteresis effects on a drop sitting on an incline plane
(American Physical Society, 2019-04)
We study the contact-angle hysteresis and morphology changes of a liquid drop sitting on a solid substrate inclined with respect to the horizontal at an angle α. This one is always smaller than the critical angle, αcrit, ...
Wetting behaviour of silicon nitride ceramics by Ti-Cu alloys
(ELSEVIER SCI LTD, 2008)
The wetting of Ti-Cu alloys on Si3N4 was analyzed by the sessile drop method, using an imaging system with a CCD camera during the heating under argon flow. The contact angle was measured as a function of temperature and ...
Hydrophilization of PVC surfaces by argon plasma immersion ion implantation
(Kluwer Academic/plenum Publ, 2003-03-01)
Commercial polyvinylchloride (PVC) sheets were treated by plasma immersion ion implantation, PIII. Samples were immersed in argon glow discharges and biased with 25 kV negative pulses. Exposure time to the bombardment ...
Effects of aging on chlorinated plasma polymers
(2017-07-01)
Thin films deposited from propanol-chloroform-argon mixtures by plasma enhanced chemical vapor deposition at different partial pressures of chloroform in the feed, CCl, were characterized after two years of aging and their ...
INFLUENCE OF GLYPHOSATE CONCENTRATIONS ON SPRAY SOLUTION PHYSICOCHEMICAL CHARACTERISTICS AND DRIFT POTENTIAL
(Soc Brasil Engenharia Agricola, 2020-01-01)
The herbicide glyphosate is sprayed with varying application volumes that result in different concentrations used in the spray solutions. Thus, this study aimed to evaluate the effect of glyphosate concentrations on the ...
Water Flow in Silica Nanopores Coated by Carbon Nanotubes from a Wetting Translucency Perspective
(American Chemical Society, 2019)
Nearly frictionless water transport makes carbon nanotubes promising materials for use as conduits in nanofluidic applications. Here, we conduct molecular dynamics simulations of water flow within amorphous silica nanopores ...
A New Framework to Quantify the Wetting Behaviour of Carbonate Rock Surfaces Based on the Relationship between Zeta Potential and Contact Angle
(2020-02-23)
This study introduces a new framework to quantify the wettability of powdered carbonate rock from existing correlations between zeta potential and contact angle. The new framework has the potential to be faster and cheaper ...
Drops with non-circular footprints
(American Institute of Physics, 2016-04)
In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. These drops are consequence of the breakup processes occurring in thin films when anisotropic contact ...
Superhydrophobic polyethylcyanoacrylate coatings. Contact area with water measured by Raman spectral images, contact angle and Cassie-Baxter model
