  　View Summary

  <p>Tunable colloidal photonic crystal films consisting of loosely packed colloidal crystals immobilized in elastomers were prepared. The prepared soft film was adhered to an aluminum specimen and the tensile testing was performed. Before applying the tensile force, the film exhibited red color due to Bragg reflection from (111) lattice planes of the face-centered cubic structure, which are parallel to the film surface. With increasing strain on the specimen, the Bragg wavelength of the colloidal crystals was blue-shifted, mainly owing to reduction of the lattice spacing. Consequently, the color of the film changed to orange, yellow, and green in accordance with increasing strain. The prepared films can be used as simple sensors that detect the strain on the materials to which they are adhered based on color change.</p>

  　View Summary

  <p>A mixture of soybean oil and hexane and ultrapure water containing a surfactant were injected into hexane-resistant glass capillary microfluidic devices to generate monodisperse oil/water emulsions. The diameter of the oil droplets was adjusted to be within the range of 2.7–15.6 µm by changing the water phase flow rate. By evaporation of hexane dissolved in the droplets, monodisperse soybean oil emulsions with droplet diameters of 0.5–3.1 µm were prepared. The present method is useful for the preparation of monodisperse emulsions with small droplets and could be used to prepare emulsions with smaller droplets by increasing the hexane concentration.</p>
