□ Composition Analysis
Al, Si is almost insoluble to each other at rsoom temperature.
All solid phase will have either 100% Al phase or 100% Si phase.
and intensified photodiode array detector (Princeton Instrument co., IRY1024, USA) at room temperature.
3. Results and Discussion
3.1 Structural Properties
Fig.1. presents cross-sectional FE-SEM images of all the samples. For all the samples, the columnar shaped ZnO grains grown normal to the substrate surface are clearly seen. When MZO and GZO films are deposited after ZnO films, it s
and starchy materials. There is a competition between these two feedstocks for fuel ethanol production. While sugar substances were the feedstock for more than 60% of fuel ethanol production at the beginning of the 2000s, its share decreased to 47% by 2006, when grains accounted for 53% of the production.
Ethanol has a potential market as big as the oil market. It can potentially replace the en
Ⅰ. X선(엑스선)회절실험 소개
1912년 X-선의 파장을 측정하는 방법이 개발되었다. 회절을 이용한 측정법이 가장 이상적인 것으로 생각되었으나 만족할 만한 결과를 얻기 위해서는 회절격자의 인접선 사이의 간격이 빛의 파장과 거의 같아야 하며, 이와 같이 X-선의 파장에 대응되는 좁은 간격의 회절격
and reassembled in an abstracted form — instead of rendering objects from a single fixed angle, the artist depicts the subject from multiple angles simultaneously as an attempt to present the subject in the most complete manner. Often the surfaces of the facets, or planes, intersect at angles that show no recognizable depth. The background and object (or figure) planes interpenetrate one an
