like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development is still slight. To develop fuel cell technique as the core industry, we have to construct effective infrastructures from extraction to supply. So, in this project, our team has searched the fuel cell technique dividing into four parts ; extraction, storing, type, merits & demerits.
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

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

It is helpful to first review what TMB PROCESS is, and how it works.
In TMB process, Solvent and adsorbents flow in opposite direction.
it makes a contact of countercurrent, then more efficient separation can be obtained.
if A has strong selectivity than B, adsorbent carries around A. and then eluent carries around B.
But TMB process is hard to perform in real world.
Because it

1. Background of study
Although the name of 'QR code' was difficult to remember at first, the recognition rate of 'QR Code' is increasing day by day. As smart phones have become popular globally, various marketings which are using it have appeared. One of the typical marketings is QR code marketing. If QR code which is also called 2D barcode is scanned, it simpl

Humankind in modern society has been leading an affluent life by virtue of the rapid scientific progress. However, we are never safe from natural disasters such as a typhoon and an earthquake which are powerful enough to bring it down.(A Research on the Actual Condition of the Victims of Natural Disasters in Korea and

2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.
