  Abstract
  Construction of Einstein field equations for the freely falling shell is explained. Modifications of gravitational theory from Newtonian view to quantum complexity is analyzed and discussed. Gravity has been revisited and treated as component of quantum complexity. Proposed cause of bodies falling into the black hole may be due to the changes occurring in the quantum complexity. Trajectory of infalling object is derived with trajectory of quantum complexity. A possible connection for quantum mechanics and general relativity is discussed. Some specialized theories such as holographic principle is also discussed for gravity which treat gravity as illusion. Relationship between gravitational attraction and changes in quantum complexity is elaborated.

  Abstract
  The hybrid organic-inorganic nanocomposite of silica nanoparticles with transparent polymer poly (methyl methacrylate) (PMMA) were synthesized by Wet chemical method. To start with, the silica nanoparticles were created by utilizing tetraethoxysilane (TEOS) and ethanol as starting materials. The surface of nanoparticles was modified by surface modifier Cetyltrimethylammonium Bromide (CTAB). In situ polymerization of MMA (methyl methacrylate) was done with the synthesized nanoparticles to form core shell structured organic-inorganic hybrid composites. The thin films of hybrid nanoparticles of Silica-PMMA were prepared by spin coater method on the substrate of glass. These composite particles were investigated by UV–Vis spectrophotometer and Fourier Transform Infrared Spectroscopy (FTIR). The structural and morphological investigations were also done with X ray diffraction (XRD) and High Resolution Transmission electron microscopy (HRTEM) respectively.

  Abstract
  Polycyclic aromatic hydrocarbons (PAHs) appear to be ubiquitous in terrestrial atmosphere as well as in the interstellar medium (ISM). In the astrophysical context presence of PAHs is interpreted by the observations of mid-IR emission bands at 3.3, 6.2, 7.7, 8.6, 11.2 and 12.6 micron (3030, 1610, 1300, 1160, 890 and 790 cm-1). The profile of these emission bands exhibit definite variations from source to source, which are explained due to sources having different types of PAHs in different ionization states. The model spectra of mixtures of PAHs show good fit for most bands except for the 6.2 micron feature. Thus a wider variety of PAHs need to be considered for this feature. Therefore, in the present work phenyl substituted phenanthrenes are studied. PAH formation in circumstellar medium of planetary nebulae and dense clouds do indicate formation of phenyl radical and phenyl substituted PAHs. To understand the modifications in infrared lineaments upon phenyl substitution and also due to substitution at different positions, study is made on the five isomers of phenylphenanthrene. The features that may account for possible phenylphenanthrenes in protoplanetary nebulae atmospheres are discussed. Possible contribution of phenylphenanthrenes towards the 6.2 micron feature and other astrophysical emission bands is assessed.

  Abstract
  Sodium borotellurite glasses in the system xNaF2-(20-x)Na2O-40B2O3-40TeO2 ((0 < x < 20 mol%) were ready by melt quenching method. The density, molar volume and optical parameters were calculated for present glasses with increasing NaF2 concentration. The results shows that the calculated parameters strongly depends on increasing NaF2 concentration. The density reduction is due fluorine ions will enters interstitial spaces of the network and breaking B-O-Te bonds which results decreasing density of the present glasses. The thermodynamically parameters such as glass transition temperature and onset of crystallization temperature of the present glasses and were found to decrease as a function of NaF2 concentration. A shift of UV absorption edge to longer wavelength indicating reduction in the number of NBO’s with increasing fluorine concentration. When NaF2 introduced in glass network, fluorine ions break the network effects in a depolymerization, i.e. B-O-Te bonds are broken and non-bridging oxygen’s are made hence the decreasing band gap energy observed in the present glasses.

  Abstract
  X-ray absorption fine structure (XAFS) at the K-edge of copper has been studied in some copper (II) complexes with substituted anilines like (2Cl, 4Br, 2NO2, 4NO2 and pure aniline) with o-PDA (orthophenylenediamine) as ligand. The X-ray absorption measurements have been performed at the recently developed BL-8 dispersive EXAFS beam line at 2.5 GeV Indus-2 Synchrotron Source at RRCAT, Indore, India. The data obtained has been processed using EXAFS data analysis program Athena. The graphical method gives the useful information about bond length and also the environment of the absorbing atom. The theoretical bond lengths of the complexes were calculated by using interactive fitting of EXAFS using fast Fourier inverse transformation (IFEFFIT) method. This method is also called as Fourier transform method. The Lytle, Sayers and Stern method and Levy’s method have been used for determination of bond lengths experimentally of the studied complexes. The results of both methods have been compared with theoretical IFEFFIT method.

  Abstract
  A.C. conductivity of LSM thin film prepared by spray pyrolysis technique and sintered at 900OC was measured at room temperature having various strontium concentrations. The results reveal that as strontium content increases a. c. conductivity increases. The experimental results of doped LSM thin films reveal that correlated barrier hopping (CBH) model is the most suitable model to explain the a. c. conduction mechanism. The dielectric constant was measured keeping frequency constant with varying temperature and it is found that as temperature increases dielectric increases and after peak it decreases.

  Abstract
  The X-ray absorption spectra at the K-edge of copper have been recorded in five mixed ligand copper complexes having orthophenylenediamine as one of the ligand. Various X-ray absorption near edge structure (XANES) parameters, such as chemical shift, i.e., shift of K-edge of copper in complexes with respect to K-edge of copper metal, energy position of principal absorption maximum and edge-width have been determined. Copper has been found to be in oxidation state +2 in all the complexes. From these XANES data the effective nuclear charge on copper and percentage co-valency in these complexes has been estimated.

  Abstract
  The neutron induced reaction cross section of eleven stable isotopes of Platinum and Osmium i.e. 192Pt(n,α)189Os, 194Pt(n,α)191Os, 195Pt(n,α)192Os, 196Pt(n,α)193Os, 198Pt(n,α)195Os 184Os(n,α)181W, 187Os(n,α)184W, 188Os(n,α)185W, 189Os(n,α)186W, 190Os(n,α)187W and 192Os(n,α)189W have been calculated by using software TALYS 1.4 in the energy range between 13MeV to 15MeV. The present situation of (n, α) reaction cross section data for the energy region just below and above the 14MeV threshold region is important for reactor technology but as of now it is still extremely little and discrepant. Thus, the precise cross- sections of all kinds of nuclear reactions are very important and necessary. The result obtained has been compared with several experimental values taken from EXFOR data file and the updated evaluated data file of ROSFOND-2010, JEFF-3.2 and JENDL-4.0.
