Fumed silica is synthesized by the pyrolysis method in which silicon tetrachloride reacts with oxygen in a flame, and the SiO 2 seed grows in size or aggregates .The sol–gel process [9,10] is performed in a liquid phase and silica nanoparticles are synthesized with an acidic or basic catalyst and alcoholic solvent in the presence of silicon alkoxide.
Zn doped mesoporous silica nanoparticles (Zn-MSNs) with uniform distribution of Zn, large specific surface area and ordered mesoporous channels were prepared by a sol–gel method. The incorporation of Zn-MSNs could significantly improve the mechanical and antibacterial properties without compromising the cytocompatibility of the dental resins.
In this article, we report our novel results on the double-pulse processing approach on the improvement of chemical etching anisotropy and >30% faster processing speed in fused silica. The effects of pulse delay and pulse duration were investigated for further understanding of the relations between nanograting formation and etching.
