Won HJ, Pyo YS, Oh SS, Kim YC, Kim YS, Hwang JHet al., 2006, Fabrication of monodisperse silica spheres using statistical design of experiments, Metals and Materials International, Vol: 12, Pages: 95-99, ISSN: 1598-9623

The statistical design of experiments was successfully carried out in order to synthesize monodisperse silica spheres using a fractional factorial design with a resolution of V. In this design, the input variables were the temperature, the concentration of NH3, the concentration of TEOS, the methanol/n-prophyl alcohol ratio, and the distilled water. The output variables were the particle size, standard deviations, and the degree of agglomeration. Simultaneous consideration of the particle characteristics allowed for an optimum regime in the experimental conditions in addition to an understanding of the experimental variables. The concentrations of TEOS and distilled water are determined to be statistically significant variables for the controlling of the particle sizes. The size of the monodisperse silica spheres was found to be approximately 400 nm.

Wong S, Saba M, Hess O, Oh SSet al., Gapless Unidirectional Photonic Transport Using All-Dielectric Kagome Lattices

Photonic topological insulators are a promising photonic platform due to thepossibility of unidirectional edge states with insensitivity to bending,fabrication imperfections or environmental fluctuation. Here we demonstratehighly efficient unidirectional photonic edge mode propagation facilitated bythe optical quantum valley Hall effect. With an all-dielectric kagome latticedesign, we demonstrate broadband suppressed reflection in the presence of sharpcorners and further show negligible vertical losses in a semiconductor-baseddevice at telecommunication wavelengths.
