● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

1. Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules.

In the semiconductors, when the energy excesses the band gap, electrons and holes are generated.
Similar to this, photons must overcome the photonic band gap energy to generate the color.
Then, if we know the specific color band gap, we can make that color by control the atomic structures.
Also, we can use this in ‘Information and communications technology’ by controls of total internal
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

To avoid 'Worn-out room facilities'(one of weakness) and 'Lack awareness of Echo'(one of treats), remodel Commodore's facilities Eco-friendly. For example, there are theme night light which use solar heat, use of pollution-free wallpapers and tiles, and replacement of air-conditioners, TVs, lights to less electricity consu
