As a part of this study, mathematical model based on two-compartment pharmacokinetic system with general fractional derivatives was developed. Its aim to describe the release BisGMA and TEGDMA monomers from composite core resin over three time periods. For purpose, five Clearfil Photo Core samples were prepared elution measured using high performance liquid chromatography at 1, 7 28 days post-i...
The Bruggeman formalism provides an estimate of the effective permittivity of a composite material comprising two constituent materials, with each constituent material being composed of electrically small particles. When one of the constituent materials is silver and the other is an insulating material, the Bruggeman estimate of the effective permittivity of the composite exhibits resonances wi...
TiCl4, ammonia, inorganic salts as raw material, nanometer composite-crystal TiO2 powders were synthesized by two-step chemical method. Precursors were crystallized with different phase and stable composite-crystal TiO2 with anatase and rutile phase was prepared at low temperature. Quantitative control of crystal phase was realized. Remarkable factors includ...
