A metal vacuum line was constructed for preparing diluted standard mixtures at parts per billion by volume (ppbv) or <br> Traceless solid phase synthesis of isoquinolone derivatives. https://ir.lib.ncu.edu.tw/handle/987654321/34887 title: Traceless solid phase synthesis of isoquinolone derivatives. The XPS studies of the dedoping processes of polyalkylthiophenes https://ir.lib.ncu.edu.tw/handle/987654321/34885 title: The XPS studies of the dedoping processes of polyalkylthiophenes abstract: The room temperature doping and auto-dedoping processes of FeCl3 and AuCl3 doped polyalkylthiophenes were studied with X-ray photoelectron spectroscopy. The redox chemistry of both the carbon and sulfur atoms on polymer backbone was revealed with the ESCA <br> The tiny ionospheric photometer: An instrument for measuring ionospheric gradients for the COSMIC constellation https://ir.lib.ncu.edu.tw/handle/987654321/34883 title: The tiny ionospheric photometer: An instrument for measuring ionospheric gradients for the COSMIC constellation abstract: We describe the specifications for an ultraviolet radiometer for measuring the F-region electron density gradients from the Constellation Observing System for Meteorology, Ionosphere, and Climate(COSMIC). We also present a technique for determining the tw <br>
