In this paper, the physical characteristics of La0.5Ag0.1Ca0.4MnO3 and La0.6Ca0.3Ag0.1MnO3 compounds have been studied. Structural analysis by XRD showed that both samples crystallize in an orthorhombic structure. For the La0.5Ag0.1Ca0.4MnO3 sample it can be seen that there are two bands: the first is due to the stretching Mn–O bond the υs vibratio...

Magnetic nanocomposite CeO2/SrFe12O19 including a hard magnetic material (SrFe12O19) and soft magnetic material (CeO2) was prepared by a one-step chemical co-precipitation with high-temperature (900 °C) sintering method. Its structure and properties were studied using Fourier transform infrared (FT-IR), X-ray diffraction (XRD), vibrating-sample mag...

X-Ray Fundamentals

Density functional theory (DFT) calculations were undertaken to investigate the effect of Fe-doping on the capability of a graphene-like BC3 nano-sheet ([email protected]3NS) in detecting the gas SO3. The interaction of the pure BC3NS with SO3 was a physisorption, showing that it could not be used as a sensor. However, there was a considerable incr...

In this work, the shock wave response of a pore-embedded CuZr metallic glass (PEMG) under different impact velocities (0.5-1.5 km/s) and initial temperatures (300-600 K) was evaluated through the molecular dynamics (MD) simulation.
