이번 실험은 spectrofluorometer를 이용하여 250nm, 350nm에서 빛을 흡수하고 450nm에서 fluorescence를 방출하는 quinine에 대한 spectrum을 얻어 fluorescence spectroscopy로 unknown quinine의 농도를 결정하고, 특정 조건에 따른 quinine의 quenching을 확인해 보는 데에 목적이 있다. 농도 결정 실험에서 solvent가 0.05M H2SO4(aq)인 quinine sta
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

우리나라에서 발생하는 닭 깃털은 연간 4만여 톤 정도이며 거의 전부 토양에 매립하고 있다. 가금육 생성공정에서 발생되는 닭의 깃털은 케라틴(keratin)이라는 단백질 성분이 주를 이루고 있는데 일반적인 단백질 효소로 쉽게 분해되지 않기 때문에 농업 폐기물 문제의 하
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
