Immobilisation of apatite on Ti30Ta alloy surface by electrospinning of PCL
(Ice Publishing, 2017-06-01)
Surface modifications of titanium alloy have been extensively researched for the purpose of increasing the biocompatibility of medical implants. In this study, a Ti30Ta alloy surface was modified by functionalisation with ...
Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...
Surface modification of polymeric materials by cold atmospheric plasma jet
(Elsevier B.V., 2014-09-30)
In this work we report the surface modification of different engineering polymers, such as, polyethylene terephthalate (PET), polyethylene (PE) and polypropylene (PP) by an atmospheric pressure plasma jet (APPJ). It was ...
Nano-modification of Si-wafer surfaces using low-cost ambient air diffuse plasma
In this paper, we demonstrated the cleaning and nano-oxidation of Si-wafer surfaces by atmospheric pressure plasma, generated in ambient air using diffuse coplanar surface barrier discharge. Plasma treatment for one second ...
Surface modification of siloxane containing polyurethane polymer by dielectric barrier discharge at atmospheric pressure
Surface treatment of polymers by discharge plasmas is of great and increasing industrial application because it can uniformly modify the surface of treated samples without changing the material bulk properties. Present ...
A surface modification for hydrogen storage intermetallic particles by sol-gel method
A new process for the surface modification of hydrogen storage intermetallic particles used as anode material in secondary batteries is proposed in this article. The copper oxide particles coverage obtained by the sol-gel ...
Surface modification of Ti dental implants by Nd: YVO4 laser irradiation
(Elsevier B.V., 2007-09-30)
Surface modifications have been applied in endosteal bone devices in order to improve the osseointegration through direct contact between neoformed bone and the implant without an intervening soft tissue layer. Surface ...
ACTIVATION OF HMDSO THIN FILMS WITH LOW PRESSURE ARGON PLASMA AND VACUUM ULTRAVIOLET RADIATION

Investigations on the stability of plasma modified silicone surfaces
(Kluwer Academic/plenum Publ, 2004-03-01)
In this work it was investigated the effect of the exposure to different plasmas on the wettability of silicone samples. We have observed that oxygen. argon, and hydrogen glow discharges are quite effective in reducing the ...
Cell and Bacteria-Baterial Interactions on the Ti10Mo8Nb Alloy After Surface Modification
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2018-01-01)
The purpose of this study is the surface modification of Ti10Mo8Nb experimental alloy by using TiO2 nanostructure growth. Ingots of the Ti10Mo8Nb experimental alloy were produced by fusion from sheets of molybdenum, niobium, ...
