Abstract:
The present invention relates to a method and an apparatus of manufacturing a photonic crystal structure capable of simplifying a manufacturing process and improving effectiveness. The method of manufacturing a photonic crystal structure comprises a step of providing a colloidal solution including photoreactive particles to a subject; a step of crystal-structuralizing the photoreactive particles; and a step of rotating the subject while crystal-structuralizing the photoreactive particles, wherein centrifugal force is applied to the photoreactive particles.
Abstract:
The present invention relates to hydrazine and hydrazine derivatives which are used for storing carbon dioxide or converting the carbon dioxide into useful compounds by effectively capturing the carbon dioxide and, more specifically, to hydrazine and hydrazine derivatives which can be used as a carbon dioxide absorbent and have excellent thermal stability, high absorption ability of carbon dioxide at atmospheric pressure, and is generated with less energy. Additionally, the hydrazine and hydrazine derivatives can be used as an efficient and stable absorbent with less decomposition of the absorbent during sorption and desorption of the carbon dioxide, thereby showing economic efficiency.
