Physico–Chemical Characterization of Dentinal Surface Treated with Atmospheric- Pressure Plasma

Aluminium 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). ...

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...

Modification 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...

Modeling Studies of Atmospheric Pressure Microplasmas: Plasma Dynamics, Surface Interaction

Technologies based on atmospheric-pressure microplasmas (APMs) have been widely developed due to their unique nature such as its non-equilibrium state and capability for high pressure operation. Electrophotographic printing, sensors, surface functionalization and plasma medicine are typical applications of APMs. However, obtaining accurate measurements of key plasma parameters is challenging du...
