2.1 XRD를 이용한 고분자의 분석
2.1.1 금속과 고분자의 차이
금속은 결정으로 되어있다. 그래서 XRD를 이용해 그 구조를 알 수 있다. 더 나아가서는 그 금속이 무엇인지를 찾아서 알 수도 있다. 하지만 고분자는 비정질로서 결정을 가지고 있지 않다. 정확한 위치에서 회절이 일어나지 않으며 back
2. Betty Crocker

3. Gold Medal
They select the best grades of premium wheat and perform quality checks throughout the milling process. The means consumers are assured of consistent results – time after time, recipe
This material can also be used as anti-reflection layer. The required index of refraction for this layer to act as anti-reflector is 1.9 and SiON has refractive index ranging from 1.8 to 2.0. By applying this encapsulation technique, cell gets a value of 2% reflectivity. The enhanced corrosion resistance may make it more stability and longer lifetime of amorphous silicon solar cell.
