films formed by stepwise self-assemblyof ~6 nm Au particles and organic di- thiol on mercaptosilane-functionalized glass substrates. The thin films produced have been studied by UV/Vis spectroscopy, ellipsometry, scanning tunneling microscopy, and temperature-dependent conductivity measurements. The results show that the Au parti- cles are well-protected by the dithiol linker molecules and do not

※IR spectrum
아래 Fig. 1의 IR spectrum은 일반적으로 흔히 사용되고 있는 IR spectrophotometer로 얻은 thin polystyrene film의 IR spectrum이다. 여기에서 알 수 있는 바와 같이, 가로축은 파수로 되어 있으며(파수로 할 경우 선형적이다) 세로축은 투광도(%)이다. 근래에는 사용 목적에 따라 두 축을 T-λ, A-λ 또는 A-
1) Meaning of consumption in the specific context
At the beginning of the film, the main character went to the hospital to inquire about the plastic surgery, saying that "I just want to live like a normal person even one day, not because of the vanity ". and it was the most important reason for doing the plastic surgery which she thought important and invaluable consumption for her. the real
[3] Thin Film Deposition
초집적 반도체를 구성하는 소자들은 그 특성상 그 크기가 매우 얇아(작고) 미세한 조직을 가진다. 그리고 이것은 박막 증착(TFD = Thin Film Deposition) 공정을 통해 제작된다. 박막 증착이란 이름 그대로 표면에 얇은 막을 씌우는 기술을 뜻하는데 이 공정을 통해 기판(substrate)이나 이전에

Synthesis of PVAc and PVA
2.Objective
PVA(poly vinyl alcohol) is prepared by hydrolysis of PVAc, which is synthesized by emulsion polymerization of vinyl acetate.
3.Theory
◇ Background
-PVA
Polyvinyl alcohol has excellent film forming, emulsifying, and adhesive properties. It is also resistant to oil, grease and solvent. It is odorless and nontoxic. It has high tensile
