surface morphology and roughness of the films was observed by field emission scanning electron microscopy (FE-SEM, Model: JSM-6701F) and atomic force microscopy (AFM, Digital Instrument, nanoscope III) operated at room temperature, respectively. The electrical properties of the films were determined using Hall measurement system (Van der Pauwconfiguration, Hilton, Australia) at room temperature.
task currently important.
Regulation of nanoparticles.
Size : 10~100nm (EPR effect)
Coating PEG polymer
Why nanoparticles?
1) It can deliver a larger quantity of drugs with better safety.
2) Easy to attach targeting ligands.
3) It is enough size to deliver multi-drugs.
4) Can regulate releasing of drug particles.
5) Can avoid multidrug resistance through cell-surface protein pump.
위 그림은 Oil Sands에 Bacteria를 넣어줌으로써 Bacteria가 oil과 water의 interface에서 oil을 degradation 할 수 있도록 해주는 것이다. Bacteria는 oil과 같은 hydrocarbon을 degrade시켜서 methane gas를 배출한다. Oil Sands가 전부 degradation되어 methane gas로 변하고 나면 우리는 단순히 이 천연가스를 뽑아내기만 하면 될 것이다. 이

3. Method of Research
To progress this research, the research team will mainly consult former theses about North Korea Collapse and historical examples of U.N. intervention. Press release such as articles and news will be the secondary material to use. Also, the research will definitely reflect academic advisor (Professor Chung Kyung-young)'s feedback.
Like a finger in the macro world so feels a tiny tip on a lever in the nano world a surface Forces are in Pico Newton range the same like intermolecular binding forces
1-1. AFM tip
- actually feels the sample surface.
- silicon nitride
exhibit excellent flexibility, Contact AFM mode
- silicon crystal
high frequency oscillating(100kHz), more stiffer than silicon nitride, non co
