Anion engineering in lithium cobalt oxide for application in high-performance supercapacitors
Figure 2 illustrates the FTIR spectra of LiCoO2 and LiCoO1.6(F0.8Cl0.2)0.4. In the spectrum of LiCoO2, the peaks at 555 and 600 cm−1 are attributed to the symmetric and asymmetric vibrations of O–Co–O in the octahedral sites35. The…

High-resolution high-throughput spatiotemporal strain imaging reveals loss mechanisms in a surface acoustic wave device
Surface acoustic wave device fabrication
Black Y-cut LiNbO3 wafers were immersed in Caro’s acid (H2SO4:H2O2 9:1) for 10 min and then rinsed in deionized (DI) water at 80 °C. The wafers were then immersed in an RCA surface clean 1 solution,…

Study of Z-scan technique, dispersion energy, and Wemple–DiDomenico model on Cu, Cr and Fe doped NiO nanopowder for the determination of nonlinear and linear optical characteristics
Structural studies
Figure 3a shows that all the synthesized samples possess a polycrystalline cubic structure. For both pristine and doped NiO samples, the diffraction peaks at 37.37°, 43.41°, 62.98°, 75.51°, and 79.50° are attributed to the…
