TENACITY AND PERSISTENCE OF COPPER FUNGICIDES IN CITRUS SEEDLINGS UNDER SIMULATED RAINFALL
(Univ Fed Rural Semi-arido-ufersa, 2016-01-01)
The amount of fungicide that adheres to the leaf during spraying and the amount that remain on the leaf after weathering are the main factors that defines the amount of active residue on the leaf surface to effectively ...
Aging of plasma-activated copper and gold surfaces and its hydrophilic recovery after water immersion
(Elsevier B.V., 2014-01-01)
A significant increase of surface hydrophilicity of copper and gold surfaces was obtained after atmospheric pressure plasma treatment using the surface dielectric barrier discharge with specific electrode geometry, the ...
Behaviour of a copper-AISI 304 stainless steel mixed anode in electrolytic copper refining with periodic current reversal
(1986)
In the search for suitable materials to be used as anode supports in the periodic current reversal refining process this work covers the study of austenitic AISI 304 stainless steel. Experimental results show that the ...
Corrosion resistance and antibacterial properties of copper coating deposited by cold gas spray
(2019-03-15)
This work describes the morphology, corrosion resistance, and antibacterial performance of copper coating deposited onto carbon steel by cold gas spray (CGS). Cross-sectional images of the coating showed a dense microstructure, ...
Anti-biofilm activity and in vitro biocompatibility of copper surface prepared by cold gas spray
(2021-04-15)
In this work the cold gas spray (CGS) technique was used to produce anti-biofilm and biocompatibility copper surfaces. Copper was deposited onto carbon steel and the phase composition, morphology, porosity, and adherence ...
Anodically grown films on copper and copper-nickel alloys in slightly alkaline solutions
(Springer, 2006-02-01)
Surface oxides grown on copper and copper–nickel alloys (UNS 72000 and UNS 70600) in aerated borax-borate buffer solution of pH 7.7 were characterized using various experimental techniques. Their influence on the mechanism ...
Study of the influence of the rare earth elements (Ce3+ and Ce4+) concentration on the siloxanes coating applied on the copper surface
(2012-12-01)
This work studied the influence of the rare earth (Ce3+ and Ce4+) elements concentration in polysiloxane flints deposited on copper by dip-coating process, and evaluated their resistance in a 3.5 wt.% NaCl medium. Classical ...
