carbon dioxide. Other methods that not only help to preserve food, but also add flavor, include pickling, salting, smoking, preserving in syrup or alcohol, sugar crystallization and curing.
As the preceding paragraphs say, many kinds of food preservation technologies are around for preventing foods from the undesirable results. Specifically this report deals with the methods that inhibiting the

1.1 연구 배경
철근콘크리트 구조는 현재 가장 널리 이용되고 있는 구조의 하나이다. 철근콘크리트 구조에 사용되는 콘크리트는 경제성과 내구성능이 우수한 건설재료이지만, 시간의 경과에 따른 자연적인 노후화와 주변환경의 변화 등에 의하여 부재 및 재료 자체의 성능이 점
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
(4) Double patterning
The double patterning is divided into four parts, leading with wafer requirements and then two sets of lithographic requirements (Generic Pitch Splitting - Double Patterning Requirements Driven by MPU metal Half-Pitch and Generic Spacer Patterning Requirements - Driven by Flash). The lithography requirements are different for each process; the requirements for pitch splitti
1. Uptake Hydrogenase
1) Definition of Uptake Hydrogenase and Mechanism of Hydrogen Production
Uptake hydrogenases are Ni-Fe enzymes that catalyze the conversion of hydrogen gas to hydrogen ions and electrons. They are found in the heterocysts and not in the vegetative cells of nitrogen-fixing strains of cyanobacteria. They remove the hydrogen gas produced by nitrogenase when they carry o
