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, … WitrynaAn impurity, present in SBECD, has been shown to be an alkylating mutagenic agent with evidence for carcinogenicity in rodents.

Chemical Vapor Epitaxy of … WitrynaThe large Stokes shift between excitation and emission, 0.85 eV, is consistent with a deep-level impurity. To estimate the acceptor binding energy, resistivity measurements were performed by McCluskey et al. (2014). The resistivity was quite high (~ 10 9 Ω cm) and constant up to 400 K.
