Performance and Reliability Review of 650 V and 900 V Silicon and SiC Devices: MOSFETs, Cascode JFETs and IGBTs

IEEE transactions on industrial electronics (1982. Print), 2020
The future of power conversion at low-to-medium voltages (around 650 V) poses a very interesting debate. At low voltages (below 100 V), the silicon (Si) MOSFET reigns supreme and at the higher end of the automotive medium-voltage application spectrum ...

Combination of ICP‐OES, XRF and XRD techniques for analysis of several dental ceramics and their identification using chemometrics

Journal of Spectroscopy, Volume 26, Issue 2, Page 141-149, 2011., 2011
In this paper dental ceramic samples from seven vendors were studied. The elemental composition for each type was investigated using the ICP‐OES and the XRF. Assessment of the seven types of ceramic was also successfully achieved using the XRD spectral data and processed with Principal Component Analysis (PCA).
