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, ...
Elaboration and characterization of the electrodeposited phosphates masses doped with various ions on stainless steel
(Virtual Institute of Physics, 2014-06)
The present paper is focused on elaboration of phosphate masses with good molar ratios on SS 316L, with fluoride, Zn2+ and Cu2+ as dopant ions, using an electrochemical procedure and also the attempt to select the best ...
Chemical modification of styrene-butadiene-styrene co-polymer by grafting of N-carbamyl maleamic acid
(Brill Academic Publishers, 2004-12)
A styrene-butadiene-styrene (SBS) block co-polymer was functionalized using different amounts of N-carbamyl maleamic acid (NCMA) and benzoyl peroxide as initiator. NCMA, which is a bifunctional monomer, was synthesized in ...
Effect of the spreading solvent on the three-phase contact angle of microparticles attached at fluid interfaces
(Royal Society of Chemistry, 2010-11)
We address a systematic study of the three-phase contact angle, , of microparticles at flat fluid-liquid interfaces by using different experimental methods. We measured the dependence of not only on the particle chemical ...

Construction and calibration of a goniometer to measure contact angles and calculate the surface free energy in solids with uncertainty analysis
(Elsevier, 2018-12)
Here, we present the construction and calibration of a low-cost goniometer to measure contact angles by the sessile drop method. Besides, we propose a simple and fast method to calculate the uncertainty in the determination ...
Improvement of Cr-Co-Mo membrane surface used as barrier for bone regeneration through UV photofunctionalization: An in vitro study
(MDPI AG, 2017-07)
Although there are several studies of the ultraviolet (UV) light-mediated photofunctionalization of titanium for use as implant material, the underlying mechanism is not fully understood. However, the results of in vitro ...
