Surface modification of Ti implants by plasma oxidation in hollow cathode discharge
(Elsevier, 2006-01-24)
Comportamento em fadiga da liga Ti-6Al-4V para uso biomédico com superfícies modificadas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2011-09-09)
Surface modification in implants is used, basically, to improve osseointegration, which is defined as the intimate contact between bone and implant material, without a soft tissue layer in the bone/implant interface. ...
Impact of surface roughness on the self-assembling of molecular films onto gold electrodes for label-free biosensing applications
(2021-05-10)
The properties of molecular films assembled over gold electrode surfaces are prone to reflect fabrication characteristics. Here we show the importance of controlling electrode surface characteristics of a gold interface ...
Effect of airborne particle abrasion protocols on surface topography of Y-TZP ceramic
(2012-04-01)
This study aimed to evaluate Y-TZP surface after different airborne particle abrasion protocols. Seventy-six Y-TZP ceramic blocks (5×4×4) mm3 were sintered and polished. Specimens were randomly divided into 19 groups (n=4) ...

Adherence in vitro of Candida albicans to plasma treated acrylic resin. Effect of plasma parameters, surface roughness and salivary pellicle
(Pergamon-Elsevier B.V. Ltd, 2010-10-01)
The adhesion of Candida albicans to surfaces is the prerequisite for occurrence of denture stomatitis.Objective: Hence, this study investigated if surface modifications with plasma treatments could reduce the adherence of ...

Control and suppression of vortex shedding from a slightly rough circular cylinder by a discrete vortex method
(2020-09-01)
A discrete vortex method is implemented with a hybrid control technique of vortex shedding to solve the problem of the two-dimensional flow past a slightly rough circular cylinder in the vicinity of a moving wall. In the ...
Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
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 ...
