A medium-scale volume dielectric barrier discharge system for short-term treatment of cereal seeds indicates improved germination performance with long-term effects
(2021-01-28)
Atmospheric pressure plasma has the potential of being applied in pre-harvest processes as a sustainable technology for seed and plant treatment. In this study, a medium-scale volume dielectric barrier discharge reactor ...
Polyurethane paint adhesion improvement on aluminium alloy treated by plasma jet and dielectric barrier discharge
(2016-01-17)
The effect of atmospheric pressure plasma treatment on the adhesion between a protective coating and AA1100 alloy was investigated. Two plasma sources were used for surface modifications: atmospheric pressure plasma jet ...
Plasma nitriding and nitrocarburising of a supermartensitic stainless steel
(2012-03-01)
Supermartensitic stainless steels (SMSSs) are a new generation of the classic 13%Cr martensitic steels, lower in carbon and with additional alloying of nickel and molybdenum offering better weldabilty and low temperature ...
Surface properties and corrosion resistance of SF6 plasma-treated polyester-based thermoplastic elastomer
(2018-01-01)
Copolyester thermoplastic elastomers (COPE) have interesting mechanical properties but low chemical resistance in aggressive environments. Developing a treatment that would increase their chemical resistance while preserving ...
The Effect of Different Plasma Treatments on the Surface Properties and Bond Strength between Lithium Disilicate and Resin Cement
(2020-01-01)
Purpose: To evaluate the roughness, surface energy, and the bond strength of lithium disilicate yielded by two different types of nonthermal plasma (NTP), oxygen- or argon-based, compared to the conventional method. Materials ...
Antimicrobial effect of plasma-activated tap water on staphylococcus aureus, escherichia coli, and Candida albicans
(2021-06-01)
In this study, the potential antimicrobial activity of plasma-activated tap water (PAW) was evaluated against Staphylococcus aureus, Escherichia coli, and Candida albicans. For this, PAW was prepared in a gliding arc plasma ...
Surface functionalization of polyvinyl chloride by plasma immersion techniques
(2021-04-01)
In this work we discuss the wettability, chemical composition, surface morphology and optical transmittance of polyvinyl chloride (PVC) samples treated by Plasma Immersion and by Plasma Immersion Ion Implantation. The total ...
Surface characterization of different surface treatments associations with plasma and bonding analysis of Y-TZP and the veneering ceramic
(2021-01-01)
Objectives: To characterize the surface of zirconia (Y-TZP) submitted to different surface treatments (with and without plasma associations) and to evaluate the shear bond strength (SBS) between veneering ceramic (VC) and ...
Reduction of bacterial adhesion to biocompatible polymer surfaces via plasma processing
(2011-12-01)
Plasma processing of the surfaces of biomaterials is interesting because it enables modification of the characteristics of a surface without affecting bulk properties. In addition, the results are strongly influenced by ...
