Significantly higher surface area and much narrower pore size distribution in the mesopore region
A large amount of amine-type CO2 capturing agent into its mesopores in a well dispersed manner
Synthesis of MA
PEI impregnation on MA
Amine grafting on MCM-41
Characterization of the materials prepared
CO2 adsorption-desorption measurement
Al(i-PrO)3 (41.68g)+ Alcohol solvent
instrument composition
-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

- 압축기에 유입된 공기는 임펠러의 회전력에 의해 통상
40,000~100,000rpm/min 의 속도로 임펠러 중심부로 흡입
- 디퓨져는 공기 유로로서 공기의 속도를 감소시켜 감소되는 공기의
속도를 압력으로 변환
- 디퓨져에서 나온 공기
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
