  Abstract
  Synthesis of Copper complexes (Ni1-xCuxFe2O4) by the solid root method. XANES spectra have been recorded at the K-edge of Cu using the dispersive beam line at 2.5GeV Indus-2 synchrotron radiation source RRCAT(Raja Ramanna Centre for Advance Technology ), Indore, India. All the samples have been studied in powder form. From the Ni(1-x)Cu(x)Fe2O4 experimental measurements, the energy of the K-absorption edge(Ek),chemical shift(∆Ek), shift of the principal absorption maxima(EA),edge widths(Ew) percentage Covalency, and effective nuclear charge (ENC) in these complexes have been estimated.

  Abstract
  Flower like nano bismuth oxy chloride (BiOCl) was successfully synthesized by a simple hydrolytic method using Bi (NO3)3.5H2O as Bi source material at room temperature. The as-prepared samples were characterized by X-ray diffraction (XRD), High Resolution Field Emission Scanning Electron Microscope (HR FESEM). The results indicated that the as-prepared BiOCl sample is self-assembled hierarchically with nano sheets. The photocatalytic activity of BiOCl was tested on the degradation of the methomyl under solar light irradiation. The results showed that pesticide molecules could be efficiently degraded over BiOCl under solar light irradiation.

  Abstract
  Here for the synthesis of ZnO (Zinc Oxide) nanorods we have used hydrothermal process. Seed layers were deposited on FTO (Fluorine doped tin oxide) glass substrates using electro deposition method with zinc nitrate dehydrate. ZnO nanorods were synthesized on annealed seeded layer by hydrothermal method using hexamethylenetetramine as a precipitant and zinc nitrate dehydrate as source at different temperatures 50°C, 65°C, 75°C, and 85°C. The crystal surfaces were investigated by Scanning Electron Microscopy (SEM). SEM produces image by using electrons rather than light photons. A beam of electrons is sent by electron gun which follows the vertical path and after travelling through the magnetic lens it hits the sample. After the beam hits the sample, electrons and X-rays are ejected and collected by detector to give final image. It is found that the dimension of ZnO nanorods changed with different temperature. SEM images show that the average diameters of ZnO nanorods are about 10-15 nm by changing growth temperature. The smallest diameter of ZnO nanorods is observed while the growth temperature is equal to 50 ℃. ZnO nanorods have applications in Quantum Dot Sensitized Solar Cells (QDSSC).

  Abstract
  Here we have discussed the role of compound of metals such as ZnO, TiO2, PbS nanomaterials in QDSSC. Quantum dots have many advantages such as they form bilayer structure on the top of metal oxide, besides this it provides good carrier pathways and large interface areas for collection of carriers. PbS is used as photovoltaic material in near IR region. PbS quantum dots have also number of applications such as in nanotechnology, light emitting diodes and solar cells. In Quantum dots due to high level control over the size of crystals it is possible to have control over the band gap and conductive properties of the materials. This property makes quantum dots suitable for solar cells. Semiconductor quantum dots such as CdSe, InP, InAs, PbS, PbSe are used in solar cells. Cobalt nanoparticles are used in solar energy absorption and magnetic recording data purposes. QDSSC are less expansive and highly efficient in comparison to traditional solar cells.

  Abstract
  Determination of the orientation of the elliptical galaxies is an important problem. We determine the orientation of the light distribution of individual elliptical galaxies by combining the profiles of photometric data from the literature with triaxial models. The likelihood of obtaining the data from a model is a function of the parameters describing the intrinsic shape and the orientation. Integrating the likelihood over the shape parameters, we obtain the estimates of the orientation. Apply the methodology to determine the orientation of the galaxy NGC 741.

  Abstract
  ‘Quantum’- is one of the important and valuable names in the field of Physical Science. However, due to its importance and applications in several sectors or domains; it is treated as valuable Applied Science Field. Quantum in generally has important linkages with Physics and then Mathematics. The importance of Quantum in Computing developed a domain called Quantum Computing which is responsible for healthy and speedy Computing and Technological Science. Computing has an important relationship with Information Science. Information collection, selection, organization, processing and management and dissemination are the main roles of Information Science and for building and developing such information activities; computing tools play an important role. Thus, Quantum Computing is also helpful in better Information Science Practice and ultimately responsible for sophisticated Informatics practice. In this paper, Quantum Science and Information Science, and their integration role as Quantum Information Science; including its need, value and role are discussed and analyzed.
