The current study show the results related to investigating the Compton scattering(Cs) of Indium Antimonite (InSb). 241Am with 59.54 keV Gamm-radiations source Compton spectrometer is employed for the purpose of experimental measurement. The technique of linear combination of atomic orbitals (LCAO) is utilized within the framework of density functional theory (DFT),is used to assess the theoretical values of distributing the electron momentum density. A comparison was then made between the research findings and empirical data. Additionally, calculations employing the ionic model (IO) based on the 5p state of In and the 5p state of Sb atoms reveal that 0. 5 electrons of the state of 5pIn may have been transferred to the 5p state of Sb atoms in order to estimate the charge transfer in indium antimonite (InSb).

The structural, electronic, and optical properties were investigated by performing firstprinciples calculations within the framework of density functional theory (DFT) for zincsaturated magnesium oxide (ZnxMg1−x O) with different concentrations of Zn (x = 0, 0.125, 0.375 and 0.5). The crystal structure used in this calculation was the cubic MgO with a space group of Fm-3m with a 2x1x1 supercell. An increase in the zinc concentration increased the lattice parameters of ZnxMg1−x O and reduced the band gap of the material. The absorption function and refractive index were improved with increasing doping concentration of Zn in the ZnxMg1−x O compared to pure MgO. In addition, this information could provide a direction in the fabrication of a good photo catalyst material.

Many individuals have always found the ability to recognize human speech interesting because of the diversity of applications in virtually every industry. Improvements in human voice/speech recognition capacity and quality have been made possible via advancements in science and technology, particularly when using equipment known as a terminal. Speech recognition enables devices to alter speech data in a manner that is understandable, and this means that information has been completely identified and comprehended. The main aim of recognizing human voice is to be able to tailor information (for humans) for device use. The main goal of voice recognition systems is to allow the device to interact with the user and provide new possibilities. The growing use of intelligent terminals, as well as their substantial scientific and technological potential, calls into question the capabilities of human voice recognition in the workplace. The aim of this article is to demonstrate human speech recognition capabilities utilizing intelligent terminal devices. Also, this will primarily be investigated in the transportation (vehicle) context, where the advantages and disadvantages of these devices and concepts will be assessed.

This work investigates the electronic momentum density (EMD) distribution in nanosize zirconia (ZrO2) using the technique of Compton scattering. The ZrO2 nanoparticles (11.2nm) are synthesized of mechanical milling and characterized by SEM, XRD and TEM probes. The Compton profile J ( p z ) of nanoZrO2 is measured by Compton spectrometer 59.54KeV Gamma rays (Americium-241) source. The study finds out that EMD in nanoZrO2 is narrower comparing in case bulk ZrO2. This study adopts the ionic-model-based free atom J ( p z ) calculation for many configurations (Zr) + x (O − x ∕ 2 )2 ( 0 . 0 ≤ x ≤ 0 . 2 ) to measure the charge transfer (CT) on the compound formation. According to this study’s findings, CT values in these materials are ranged from 1.5 to 1.0 electrons from Zr to O atom.
