Witryna13 kwi 2024 · In this study, the tendency of having different grain structures depending on the impurity levels in AZ91 alloys was investigated. Two types of AZ91 alloys were analyzed: commercial-purity AZ91 and high-purity AZ91. The average grain size of the commercial-purity AZ91 alloy and high-purity AZ91 is 320 µm and 90 µm, … Witryna10 kwi 2024 · This impurity can convert (6, 3) TSC-SWBNNTs to n-type semiconductors. Also, the carbon atom has one electron less than the nitrogen atom. Hence, by replacing the carbon atom instead of nitrogen atom, a hole is injected into (6, 3) TSC-SWBNNTs. This impurity can turn (6, 3) TSC-SWBNNTs into a p-type …
