“…Using such configurations, simple atmospheric plasma systems using nitrogen, argon or helium as a carrier gas can produce high particle concentrations without requiring a complicated vacuum system. Particles have been successfully produced from ferrocene, acetylene and hexamethyldisiloxane (Vons et al 2006), and from titaniumisopropoxide for the production of titania particles (Bai et al 2004;). Furthermore, this type of plasma can also be used for gas-phase particle coating, both for particles from another DBD plasma or particles produced using other methods (e.g.…”

“…Plasma surface modification was reported as a possible method for aided mineral re-crystallization process. It can be used to produce nano-sized crystals with improved internal quality and dissolution rate, compared to conventional size crystalline products, however further research is needed for process optimization [14][15][16] . Conservative dental treatment can sometimes be painful due to heat generation with drilling.…”

This study investigated the combining effect of cold plasma and bioglass-phosphoric acid paste on demineralized enamel. Fifty bovine incisors' enamel specimens were challenged by a demineralization solution of pH 4.47 for 72 h. Specimens were divided into five groups: (I) Control, demineralized enamel (C); (II) Demineralized enamel treated with fluoride varnish (F); (III) Cold plasma application to demineralized enamel (P); (IV) Demineralized enamel treated with bioglass paste (B); (V) Application of bioglass paste to cold plasma-treated demineralized enamel (PB). Specimens were then immersed in remineralizing solution for 24 h, before being examined with micro-computed tomography (micro-CT), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and cross-sectional micro-hardness measurement. The results showed that; treating demineralized enamel with cold plasmas before bioglass application ensued a significant high mineral volume recovery and micro-hardness of demineralized region. It can be concluded that cold plasmas may improve the remineralization of bioglass on demineralized enamel.

Production of Metal Nanoparticles in Asymmetrical Dielectric Barrier Discharge-Plasma Reactor at Atmospheric PressureThis paper focuses on the production of metal nanoparticles in a dielectric barrier discharge (DBD) reactor at atmospheric pressure. In the developed reactor only one electrode is provided with a dielectric (alumina), while the point-shaped counter electrode is not covered and is accessible to the filamentary discharges (asymmetrical DBD). The metallic particles are formed from the material of the open counter electrode, on which the filamentary discharges lead to the formation of craters. A high number of larger nanoparticles (with diameter of some tens of nanometers) are observed in the cold reactor at the beginning of the discharges. After the achievement of the thermal equilibrium in the reactor mainly very small metallic nanoparticles are produced with constant size and number concentration. The produced metallic particles in thermal equilibrium are crystalline and not agglomerated. The mean diameter of the produced particles is about 4 nm. For given operating conditions of the reactor (fixed electrode gap and gas flow rate) the electrode material has almost no influence on the size of the produced particles, but it determines the number concentration.
