Iron-doped Nickel Oxide Nanoparticles Synthesis and Analyzing Different Properties

by Manar Saleh Alshatwi, Huda Abdulrahman Alburaih, Shahad Salem Alghamdi, Danah Abdullah Alfadhil, Joud Awadh Alshehri and Farah Abdullah Aljamaan

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 1422–1426, 2021; DOI: 10.25046/aj0601161

Abstract:

This is a report describing the impact of calcination on the morphological and optical properties of nanoparticles Iron doped-nickel oxide. By synthetic precipitation, the technique makes use of it. Three samples have been calcined in different temperatures and were characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), UV spectroscopy, and scanning electron microscopy…

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 151–158, 2020; DOI: 10.25046/aj050120

Abstract:

This paper describes a silicon carbide-field effect transistor (SiC-FET) gas sensor that is able to detect NO, O2, NH3, CO, and SO2. The gate of the sensor FET is a gas detection layer that consists of yttria-stabilized zirconia, nickel oxide, and platinum. The threshold voltages of the sensor depend on the target gas concentration, measurement…
