Polymer treatment by plasma immersion ion implantation of nitrogen for formation of diamond-like carbon film
(2004-09-01)
Nitrogen ions were implanted by plasma immersion in Kapton, Mylar and polypropylene, with the objective of forming a diamond-like carbon layer on these polymers. The Raman spectrum of the implanted polypropylene showed ...
The valuable role of renucleation rate in ultrananocrystalline diamond growth
(Elsevier B.V. Sa, 2012-03-01)
This is a comprehensive study of the ultrananocrystalline diamond renucleation rate. The films deposited in a hot-filament chemical vapor deposition system (HFCVD) used an argon rich environment (90 vol.%), known as ideal ...
Properties of DLC films deposited by an oxyacetylene flame
(Elsevier B.V., 1999-08-01)
Diamond-like carbon (DLC) films were obtained by spinning a tungsten carbide substrate at a high speed using an oxyacetylene flame. The films deposited at a typical experimental condition of substrate temperature of 810 ...
Effect of diamond-like carbon thin film coated acrylic resin on candida albicans biofilm formation
(2013-08-01)
Purpose: The purpose of this study was to evaluate the effect of diamond-like carbon thin films doped and undoped with silver nanoparticles coating poly(methyl methacrylate) (PMMA) on Candida albicans biofilm formation. ...
Optical and electrical properties of polymerizing plasmas and their correlation with DLC film properties
(Springer, 2004-03-01)
Diamond-like carbon (DLC) films were grown from radiofrequency plasmas of acetylene-argon mixtures, at different excitation powers, P. The effects of this parameter on the plasma potential, electron density, electron ...
Influence of CVD diamond tips and Er:YAG laser irradiation on bonding of different adhesive systems to dentin
(2013-01-01)
Aim: The aim of this study was to compare the microtensile bond strength of three adhesive systems, using different methods of dentin preparation. Materials and methods: A hundred and eight bovine teeth were used. The ...
Abutment coating with diamond-like-carbon films to reduce implant-abutment bacterial leakage
(Journal of Periodontology, 2015)
A non-hemorrhagic hybrid heparin/heparan sulfate with anticoagulant potential
(Elsevier B.V., 2014-01-02)
The structural characterization and the anticoagulant potential of a novel heparin/heparan sulfate-like compound from the heads of Litopenaeus vannamei shrimp are described. While it is distinct from either heparin or ...
Fatigue behavior of PVD coated Ti-6Al-4V alloy
(Elsevier B.V., 2011-06-01)
The aim of the present work is to identify an environmentally clean coating process that will present lower influence in the Ti-6Al-4V fatigue strength. Axial fatigue tests of Ti-6Al-4V alloy TiN, CrN and WC:H (tungsten ...
Microscopic characterization of teeth of pacas bred in captivity (Agouti paca, Linnaeus, 1766)
(Blackwell Publishing, 2007-10-01)
The microscopic description of the teeth of pacas (Agouti paca) bred in captivity was developed for providing biological data on one of the largest American wild rodents, as not many references exist in the literature about ...
