앞선 실험들을 바탕으로 하여 간이 fermenter를 제작하였다. 이를 이용하여 E. coli 의 Growth curve를 잡는다. fermenter를 설계할 때 고려해야 하는 중요한 사항은 기질(substrate)을 생성물로 전환시키는 속도(conversion rate), 생성물 수율(product yield), 생성물 농도, 생산성(productivity)을 높이는 것이다. 본
To prevent silicon from agglomerating
→ should cool the solid quickly
Rapid cooling
→ large thermal gradient in crystal
Postulate K=20W/m K
Diameter of wafer: 10-20 cm
L (latent heat of fusion) = 340 cal/g
Temperature gradient in silicon CZ (dT/dx) : 100°C/cm
