Controle da pressão em um sistema de nitretação por plasma
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrônica, 2014-11-25)
This work presents a solution to pressure control in a plasma nitriding system. The control is made by a valve between the chamber and a vacuum pump, the original valve was improved to become automatic, in addition, an ...
Electrical studies and plasma characterization of an atmospheric pressure plasma jet operated at low frequency
(American Institute of Physics, 2013-05)
Low-temperature, high-pressure plasma jets have an extensive use in medical and biological applications. Much work has been devoted to study these applications while comparatively fewer studies appear to be directed to the ...
Caracterização da alumina anódica porosa modificada por plasma
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2015-06-29)
In this study, the wettability of porous anodic alumina (PAA) surfaces modified by plasma was investigated. The porous anodic alumina films were grown on aluminum substrate using a two step anodization procedure in oxalic ...
Time-Varying Inductance of the Plasma Sheet in the PF1000 Plasma-Focus Device
(Institute Of Electrical And Electronics Engineers, 2016-05)
The time-varying inductance Lp(t) of the system formed by the coaxial electrodes and the current sheet (CS) in plasma focus (PF) discharges was calculated for the first time by Mather and Bottoms [1] on a 13-kJ PF device ...
Transfer of a cold atmospheric pressure plasma jet through a long flexible plastic tube
(Iop Publishing Ltd, 2015-04-01)
This work proposes an experimental configuration for the generation of a cold atmospheric pressure plasma jet at the downstream end of a long flexible plastic tube. The device consists of a cylindrical dielectric chamber ...
Cold atmospheric plasma jet as a possible adjuvant therapy for periodontal disease
(2021-09-01)
Due to the limitations of traditional periodontal therapies, and reported cold atmospheric plasma anti-inflammatory/antimicrobial activities, plasma could be an adjuvant therapy to periodon-titis. Porphyromonas gingivalis ...
