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 ...
Effects of O2 addition on the discharge parameters and production of reactive species of a transferred atmospheric pressure plasma jet
(2021-07-02)
The therapeutic effects of atmospheric pressure plasma jets (APPJs) have been associated with the presence of reactive species, mainly the reactive oxygen and nitrogen ones, generated in this kind of plasmas. Due to that, ...
In vitro study on how cold plasma affects dentin surface characteristics
(2021-11-01)
Purpose: Studies evaluating different features of cold plasma action on dentin surface characteristics are lacking. Thus, this in vitro study aimed to determine the effect of cold plasma under different protocols of exposure ...
Atmospheric plasma treatment of carbon fibers for enhancement of their adhesion properties
(2013-01-18)
Plasma processing of carbon fibers (CFs) is aimed to provide better contact and adhesion between individual plies without decrease in the CF mechanical resistance. This paper deals with surface modification of CFs by an ...

Innovative low temperature plasma approach for deposition of alumina films
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-11-01)
Alumina films were deposited from a new plasma method using aluminum acetylacetonate (AAA) powder as precursor. The AAA was sputtered in argon and oxygen plasma mixtures. It was investigated the effect of the oxygen ...
Evaluation of blood compatibility of plasma deposited heparin-like films and SF6 plasma treated surfaces
(2010-01-01)
In devices used in open-heart surgery and dialysis, blood must be continuously processed using extracorporeal circuits composed of peristaltic pumps and active components such as specifc flters and oxygenators. Several ...
