Exploring bismuth-doped polycrystalline ceramic Ba0.75Bi0.25Ni0.7Mn0.3O3: synthesis, structure, and electrical properties for advanced electronic applications

“…The diffraction pattern revealed that the structure of the compound is orthorhombic, belonging to the Pnma space group. The refinement of the structure was performed using the FULLPROOF tool, 20,21 confirming the successful crystallization of our molecule, which exhibited distinct large peaks.…”

“…The diffraction pattern revealed that the structure of the compound is orthorhombic, belonging to the Pnma space group. The renement of the structure was performed using the FULLPROOF tool, 20,21 conrming the successful crystallization of our molecule, which exhibited distinct large peaks. The Rietveld method was employed to rene the structure further, yielding important parameters related to the unit cell (a, b, and c), and the volume of the unit cell (V).…”

Investigating Fe-doped Ba0.67Ni0.33Mn1−xFexO3 (x = 0, 0.2) ceramics: insights into electrical and dielectric behaviors

“…An intriguing observation emerges as the introduction of iron doping leads to a single-phase composition, devoid of any indications of secondary phases according to conventional interpretations of the XRD spectra. For an in-depth exploration of the structural attributes, the researchers harnessed the FULLPROF soware [17][18][19] in conjunction with the Rietveld method 20,21 for structure optimization. Comprehensive outcomes of the Rietveld renement are documented in Table 1.…”

Highly Efficient NO2 Sensors Based on Al-ZnOHF under UV Assistance

“…The NO2-sensing process is shown in Figure 8. When exposing Al-ZnOHF sensors to NO2 without UV light, the NO2 molecules are ionized into NO by capturing conductive band electrons, leading to an increase in resistance (Reaction (4)) [49]. In comparison, the…”
