알루미늄 부품의 표면상에 단단하고 투명한 산화 피막을 만든다.
다시 말하면, 아노다이징이란 금속(부품)을 양극에 걸고 일반적으로 산용액에서 전해하여, 양극에서 발생하는 산소에 의해서 소지금속과 대단한 밀착력을 가진 산화피막(산화알루미늄: Al2O3 )을 생성한다.

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

1. SVE(soil vapor extraction-in situ)
1) principle
Soil vapor extraction, also known as soil
venting or vacuum extraction, is a cleanup
technology commonly used to remove
VOCs in vapor from contaminated property.
4) Application
Contaminant : VOCs
Place : gas station base, industrial base,
military base
Layer : contaminated
1) Make taste desirable
2) Increasing stability of food
3) Extend shelf-life
- Separation process
- Mix existing olis and solvent or crystallization
(separation by solubility at low temperatures)
- coconut oil, palm oil,and palm kernel oils are
fractionated to produce oils of different chemical
composition (Viscosit
