Phase
behaviors of metals have been modeled with colloidal systems.
Inspired by the thermal treatment of metals, we design colloidal counterparts
confined in microcapsules that show cooling rate-dependent crystallization
behavior and optical properties. Thermoresponsive colloidal particles
are highly concentrated in microcapsules to make colloidal crystals.
The crystals melt upon heating and particles recrystallize upon cooling
due to reversible change of the volume fraction. The crystallization
behavior strongly depends on the cooling rate, similarly to metals.
For slow cooling, large single-crystalline grains are grown from the
inner wall of microcapsules by heterogeneous nucleation and merging.
By contrast, fast cooling causes both homogeneous and heterogeneous
nucleation, resulting in small crystallites with random orientations
in the inner volume. This structural variation changes optical properties
originated from Bragg diffraction. The slowly cooled microcapsules
display structural colors from the entire projection that are bright
and orientation-dependent. The fast-cooled microcapsules show axisymmetric,
rotation-independent color patterns in the projection. As the thickness
of crystalline grains that align parallel to the inner wall decreases
along with the cooling rate, so does the color brightness and reflectance.
Recently, design semiosis stands out in been developing industrial goods. It is that form of product has meaning. Is changing to company's image with concept of CIPD (Corporate Identity through Product Design). Now, it is that consumer's awareness changes to side that the much wealths prefer product that have better design than product that have function. Accordingly, each company is changing to development of design putting first in product development of function putting first. Is changing by entertainment robot and so on in industrial robot for production as well as robot development purpose. Therefore, need design method of robot based on design to developed robot forward. For this, must decide basis Design from development step of robot. And need correct synthesize use subject and purpose. In this PAPER, recognize about effect of when design compares applied case and other that is not so and applied design to robot. Establish target to apply in design of small size mobile robot and consider above thing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
