  • Comparison of EXAFS foil spectra from around the world 
    Kelly, S.D.; Bare, S.R.; Greenlay, N.; Azevedo, G.; Balasubramanian, M.; Barton, D.; Chattopadhyay, S.; Fakra, S.; Johannessen, B.; Newville, M.; Pena, J.; Pokrovski, G.S.; Proux, O.; Priolkar, K.R.; Ravel, B.; Webb, S.M. (Journal of Physics: Conference Series. 190(1); 2009; Article ID: 012032)
    The EXAFS spectra of Cu and Pd foil from many different beamlines and synchrotrons are compared to address the dependence of the amplitude reduction factor (S02) on beamline specific parameters. Even though S02 is the same ...
  • Effect of rare earth size on structural, magnetic and transport properties of RBaCo(2)O(5.5) 
    Ganorkar, S.; Priolkar, K.R.; Sarode, P.R.; Banerjee, A. (AIP Conference Proceedings. 1447; 2012; 1141-1142.)
    Oxygen deficient double perovskites RBaCo(2)O(5.5) (R=Pr, Nd, Sm, Gd and Y) has been studied by XRD, magnetization and resistivity measurements. It has been found that the as rare earth size decreases, the distortions in ...
  • Hybridization effects in Ni-Mn based shape memory alloys: XAFS study 
    Priolkar, K.R.; Bhobe, P.A.; Sarode, P.R. (Advanced Materials Research. 52; 2008; 155-164)
    Martensitic and magnetic properties of ferromagnetic shape memory alloys are known to depend up on structural modulations and associated changes in the Fermi surface. These modulations although periodic and spanning over ...
  • Magnetic Compton scattering study of Ni(2)Mn(1.4)Sn(0.6) shape memory alloy 
    Dashora, A.; Mund, H.S.; Sahariya, J.; Priolkar, K.R.; Lobo, N.; Itou, M.; Sakurai, Y.; Ahuja, B.L. (Advanced Materials Research. 665; 2013; 189-193.)
    Spin momentum density in Ni(2)Mn(1.4)Sn(0.6) shape memory alloy has been measured using magnetic Compton scattering technique. The experiment has been performed using 182 keV circularly polarized synchrotron radiation at ...
  • Effect of carbon tailoring on magnetic properties of Mn(3)GaC 
    Dias, E.T.; Priolkar, K.R.; Nigam, A.K. (AIP Conference Proceedings. 1447; 2012; 1139-1140.)
    We have investigated the magnetic properties of antiperovskite Mn(3)GaC(x). Tailoring of carbon content affects the magnetic transition temperature of these materials. Magnetization decreases with decrease in carbon ...
  • Persistent luminescence in ZnGa2O4:Cr: An outstanding biomarker for in-vivo imaging 
    Sharma, S.K.; Bessiere, A.; Gourier, D.; Binet, L.; Viana, B.; Basavaraju, N.; Priolkar, K.R.; Maldiney, T.; Scherman, D.; Richard, C. (Proc. SPIE 8982, Optical Components and Materials. 2014; 898215-.)
    ZnGa2O4 (ZGO) is a normal spinel. When doped with Cr3+ ions, ZGO:Cr becomes a high brightness persistent luminescence material with an emission spectrum perfectly matching the transparency window of living tissues. It ...
  • Quantum phases of attractive bosons on a Bose-Hubbard ladder with three-body constraint 
    Singh, M.; Mishra, T.; Pai, R.V.; Das, B.P. (Physical Review A. 90(1); 2014; Article No. 013625.)
    We obtain the complete quantum phase diagram of bosons on a two-leg ladder in the presence of attractive onsite and repulsive interchain nearest-neighbor interactions by imposing the onsite three-body constraint. We find ...
  • Supersolid in a one-dimensional model of hard-core bosons 
    Mishra, T.; Pai, R.V.; Mukerjee, S. (Physical Review A. 89(1); 2014; Article No. 013615.)
    We study a system of hard-core boson on a one-dimensional lattice with frustrated next-nearest-neighbor hopping and nearest-neighbor interaction. At half filling, for equal magnitude of nearest- and next-nearest-neighbor ...
  • Liquid phase selective oxidation of benzene over nanostructured Cu(x)Ce(1-x)O(2-delta) (0.03 less than or equal to x less than or equal to 0.15) 
    Mistri, R.; Rahaman, M.; Llorca, J.; Priolkar, K.R.; Colussi, S.; Ray, B.C.; Gayen, A. (Journal of Molecular Catalysis A-Chemical. 390; 2014; 187-197.)
    Liquid phase direct oxidation of benzene to phenol was carried out over copper loaded on oxides such as ceria, alumina, magnesia, ferric oxide, zinc oxide with 30 percent H(2)O(2) as oxidant under atmospheric pressure. Of ...
  • Properties of poly(vinyl alcohol)-borax gel doped with neodymium and praseodymium 
    Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K.; Rai, R. (Bulletin of Materials Science. 37(2); 2014; 301-307.)
    The magnetic properties of the Mn3Ga(1-x)SnxC, 0 less than equal to x less than equalt to 1 antiperovskite compounds have been investigated in detail. Though all compounds of this series crystallize in a cubic structure, ...
