in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...

Using a solid-state-reaction method, La-doped AgNbO(3) samples of Ag(1-x)La(x)NbO(3) were synthesized and their photocatalytic activities were evaluated from gaseous 2-propanol decomposition under visible light irradiation. The photocatalytic activity and the surface area were increased by La doping, but the crystal structure and light absorption property did not change. The photocatalytic acti...

Significant efforts are continuously exerted by the scientific community to explore new strategies design materials with high nonlinear optical responses. An effective approach is alkalides based on Janus molecules. Herein, we present a remarkably boost NLO response of stacking Alkalides stacked molecule, M-n-M' (where n = 2 & 3 while M and M′ Li/Na/K) studied for structural, energetic, electri...

Nuclear parton distribution functions (NPDFs) are determined by a global analysis of experimental measurements on structure-function ratios FA 2 /F A 2 and Drell-Yan cross section ratios σ A DY /σA ′ DY , and their uncertainties are estimated by the Hessian method. The NPDFs are obtained in both leading order (LO) and next-to-leading order (NLO) of αs. As a result, valence-quark distributions a...

Abstract: We present the exact next-to-leading order (NLO) QCD corrections to dijet production at the LHC via quark contact interactions, with different color and chiral structures induced from new physics. Following the recent analysis of quark compositeness search at the LHC, we find that the NLO QCD corrections can lower the dijet cross sections by several tens percent, depending on the theo...

Theoretical predictions show that at low values of Bjorken x the spin structure function, g1 is influenced by large logarithmic corrections, ln (1/x), which may be predominant in this region. These corrections are also partially contained in the NLO part of the standard DGLAP evolution. Here we calculate the non-singlet component of the nucleon structure function, g 1 = g 1 − g 1 , and its firs...

A Monte Carlo at next-to-leading order (MC@NLO) has been constructed for the production of heavy quark flavours in photoproduction. As such, it is the first Monte Carlo event generator with next-to-leading order (NLO) accuracy for a process in lepton hadron scattering. In order to construct such an MC@NLO, the matrix element for the process has to be calculated at NLO and then be matched with a...

The decomposition reaction of niobium(V) oxytrichloride ammoniate to the oxynitride of niobium in the 5+ oxidation state was developed in a methodological way. By combining elemental analysis, Rietveld refinements of X-ray and neutron diffraction data, SEM and TEM, the sample compound was identified as approximately 5 nm-diameter particles of NbO(1.3(1))N(0.7(1)) crystallizing with baddeleyite-...

We study the effect of scheme dependence upon the NLO QCD analysis of the world data on polarized DIS. The reliability of an analysis at NLO is demonstrated by the consistency of our polarized densities with the NLO transformation rules relating them to each other. We stress the importance of the chiral JET scheme in which all the hard effects are consistently absorbed in the Wilson coefficient...
