Non-thermal atmospheric pressure plasma jet applied to inactivation of different microorganisms
Non-thermal atmospheric pressure plasma jets (APPJs) are capable of generating cold plasma plumes that are not confined by electrodes, which makes them very attractive for bio-medical applications. In the present work, the ...
Corrosion Behavior of Plasma Nitrided and Nitrocarburised Supermartensitic Stainless Steel
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2018-01-01)
Supermartensitic stainles steels (SMSS's) are a new generation of martensitic steels that have been increasingly used in oil and gas applications due to their adequate corrosion resistance and mechanical properties. In the ...
Bacterial sterilization by a dielectric barrier discharge (DBD) in air
(Elsevier B.V. Sa, 2010-06-25)
Cold atmospheric plasma treatment of microorganisms and living tissues has become a popular topic in modern plasma physics and in medical science. The plasma is capable of bacterial inactivation and noninflammatory tissue ...

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 ...
Propagation of localized structures in relativistic magnetized electron-positron plasmas using particle-in-cell simulations
(American Institute of Physics, 2015)
We use a particle-in-cell simulation to study the propagation of localized structures in a magnetized electron-positron plasma with relativistic finite temperature. We use as initial condition for the simulation an envelope ...
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 ...
