Influence of experimental variables on the measure of contact angle in metals using the sessile drop method
(Elsevier, 2015-08)
The sessile drop method is an easy and fast method used to measure the contact angle between solids and liquids. The value of the contact angle is used in surface characterization, in particular the wettability of solid ...
Minimal surfaces in S(3) with constant contact angle
(SPRINGER WIEN, 2009)
We provide a characterization of the Clifford Torus in S(3) via moving frames and contact structure equations. More precisely, we prove that minimal surfaces in S(3) with constant contact angle must be the Clifford Torus. ...
Wettability alteration of internal surfaces of pipelines for use in the transportation of heavy oil via core-flow
(Elsevier Science BvAmsterdamHolanda, 2006)
A Method for Measuring Contact Angle and the Influence of Surface-Fluid Parameters on the Boiling Heat Transfer Performance
(Asme, 2020-09-01)
An experimental apparatus and a computational routine were developed and implemented in order to obtain the sessile drop images and the contact angle measurement for different fluids and surface conditions. Moreover, ...
Wettability of Aqueous Rhamnolipids Solutions Produced by Pseudomonas aeruginosa LBI
(Springer Heidelberg, 2009-05-01)
The wetting behavior of rhamnolipids produced by Pseudomonas aeruginosa LBI strain grown on waste oil substrate and sodium dodecyl sulfate (SDS) on glass, polyethylene terephthalate (PET), poly(vinyl chloride) (PVC), ...
Relationship of contact angle of spray solution on leaf surfaces with weed control
(2021-12-01)
The weeds are important in agricultural and livestock areas because these plants can cause several damages, especially in the yield. The herbicide pulverization for weed control is the most used, but the efficiency of the ...
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 ...
