Properties of hydrogenated amorphous carbon films deposited by PECVD and modified by SF6 plasma
(Elsevier B.V. Sa, 2011-11-15)
Hydrogenated amorphous carbon (a-C:H) films were grown at room temperature on glass and polished silicon substrates using RF-PECVD (Radio-Frequency Plasma Enhanced Chemical Vapor Deposition). Plasmas composed by 30% of ...

The use of syngas from biomedical waste plasma gasification systems for electricity production in internal combustion: Thermodynamic and economic issues
(2020-05-15)
Brazil has problems with the incorrect disposal of biomedical waste (BW) and studies of new technologies to eliminate this problem is becoming increasingly important. The plasma gasification technology provides reliable ...
Characterization of an Air-Based Coaxial Dielectric Barrier Discharge Plasma Source for Biofilm Eradication
(Springer, 2018-05)
Air-based atmospheric-pressure cold plasmas are a source of charged particles, excited species, radicals, and UV rays, known to induce degradation of biomaterials. In this work we characterize an air-based Dielectric Barrier ...
Dynamic Characteristics of X-pinch Experiments Conducted in a Small Capacitive Generator: Refractive Optical Observations
(2016)
Among the dense plasmas configurations of interest for applications as a portable intense source of X-rays, the X-pinches are the most attractive by their brightness, source size, short duration and space localization, ...
Observations of Ablation Dynamics in Wire-Array Z-Pinch Experiments on the Llampüdkeñ Generator
(2012)
Wire-array Z-pinch experiments have been performed on the Llampüdkeñ generator (~470 kA in ~410 ns) [Chuaqui et al., Laser Part. Beams 15, 241 (1997)] using an overmassed load of aluminum wires. Time-resolved optical ...
Sterilization by pure oxygen plasma and by oxygen-hydrogen peroxide plasma: An efficacy study
(ELSEVIER SCIENCE BV, 2008)
Plasma is an innovative sterilization method characterized by a low toxicity to operators and patients, and also by its operation at temperatures close to room temperatures. The use of different parameters for this method ...
Tratamento da superfície do alumínio via eletrólise a plasma
(Universidade Estadual Paulista (Unesp), 2011)
This paper presents the study on the application of the electrolytic plasma for surface treatment of aluminum. A bibliographical study on the material of interest was preliminarily performed and later designed and built ...
