Time-related surface modification of denture base acrylic resin treated by atmospheric pressure cold plasma.
The changes of denture base acrylic resin surface properties under cold plasma and the relationships with time were investigated. Cold plasma treated the specimens for 30 s, 60 s, 90 s, and 120 s, respectively. Water contact angles were measured immediately after the treatment, 48 h, 15 days and 30 days later. Surface roughness was measured with 3-D laser scanning microscope. Candida albicans a...
متن کاملModification of Glass Surface by Atmospheric Pressure Plasma
A Diffuse Coplanar Surface Barrier Discharge (DCSBS) operating in air at atmospheric pressure has been used to induce changes in the surface properties of glass. The contact angles of water drop on the surface of glass, which were measured by drop shape analysis, decreased markably with plasma treatment for 1 s. With the increasing of the plasma treatment time, the contact angles of the samples...
متن کاملCharacterization of Simulated Martian Atmospheric Entry Plasma
During entry into the Martian atmosphere the friction between the surface of a probe and the atmosphere will cause thermal ionization of the surrounding air. The plasma parameters associated with this Martian atmospheric entry plasma will vary considerably depending on the spacecraft’s trajectory. The probable range of these parameters was evaluated using the existing Martian atmospheric data a...
متن کاملAluminium Surface Activation Using Atmospheric-pressure Plasma
Contact angles and Attenuated Total Reflection FTIR measurements were performed to study plasma activation of aluminium surface in air atmosphere using Diffuse Coplanar Surface Barrier Discharge plasma source. Two types of aluminium surfaces were used: i) industrially produced bulk aluminium samples; ii) thermally evaporated thin films of aluminium on glass (sets of 400 nm and 2 μm thickness). ...
متن کاملSurface Decontamination by Dielectric Barrier Discharge Plasma
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
