  • Nanometric study of nickel oxide prepared by sol gel process 
    Raut-Dessai, R.; Desa, J.A.E.; Sen, D.; Babu, P.D. (AIP Conference Proceedings. 1942(1); 2018; ArticleID_050052.)
    Nickel oxide nanopowder was synthesized by sol gel method using nickel nitrate as the starting material. Nickel oxide nanoparticles with a grain size of 15-90 nm have been studied by; small angle neutron scattering; scanning ...
  • Investigation of route to martensitic transition in Ni-Mn-In shape memory alloys 
    Nevgi, R.; Priolkar, K.R.; Righi, L. (AIP Conference Proceedings. 1942(1); 2018; ArticleID_030016.)
    The temperature dependent x-ray diffraction and magnetization measurements on the off stoichiometric Ni sub(2)Mn sub(1+x) In sub(1-x) alloys have confirmed the appearance of martensite at critical Mn concentration of x=0.35. ...
  • Random phase approximation and cluster mean field studies of hard core Bose Hubbard model 
    Alavani, B.K.; Gaude, P.P.; Pai, R.V. (AIP Conference Proceedings. 1942(1); 2018; ArticleID_030005.)
    We investigate zero temperature and finite temperature properties of the Bose Hubbard Model in the hard core limit using Random Phase Approximation (RPA) and Cluster Mean Field Theory (CMFT). We show that our RPA calculations ...
  • Magnetic properties of Fe-Nd Silica Glass Ceramics 
    Nayak, M.T.; Desa, J.A.E.; Babu, P.D. (DAE Solid State Physics Symposium. 2017; Article ID 70006-4.)
    Soda lime silica glass ceramics containing iron and neodymium have been synthesized. The XRD pattern revealed that the glass samples devitrified into multiple phases. Fe2O3 as an initial component converted into Fe3O4 in ...
  • Revealing optoelectronic and transport properties of potential perovskites Cs2PdX6 (X = Cl, Br): A probe from density functional theory (DFT) 
    Bhamu, K.C.; Soni, A.; Sahariya, J. (Solar Energy. 162; 2018; 336-343.)
    Metal-halide perovskites are rapidly emerging crystalline materials that are reasonably preferred as leading aspirant for applications in optoelectronic and thermoelectric devices. In this paper, we have thoroughly reviewed ...
  • Magnetic and spectroscopic studies of an iron lithium calcium silicate glass and ceramic 
    Nayak, M.T.; Desa, J.A.E.; Babu, P.D. (Journal of Non-Crystalline Solids. 484; 2018; 1-7.)
    A glass forming matrix consisting of SiO sub(2)-Li sub(2)O-CaO was doped with 10 percent and 15 percent molar of Fe sub(2)O sub(3) and investigated for changes in structural and bulk physical properties of the host when ...
  • Enhanced photoluminescence of CoWO sub(4) in CoWO sub(4)/PbWO sub(4) nanocomposites 
    Jeyakanthan, M.; UmaSubramanian; Tangsali, R.B. (Journal of Materials Science: Materials in Electronics. 29(3); 2018; 1914-1924.)
    CoWO sub(4)/PbWO sub(4) nanocomposites were successfully synthesized at room temperature (RT) by co-precipitation route without using any templates or surfactants and sintered at 600 degrees C for good crystallization. The ...
  • Reentrant behaviour in polyvinyl alcohol-borax hydrogels 
    Lawrence, M.B.; Desa, J.A.E.; Aswal, V.K. (Materials Research Express. 5(1); 2018; Article ID 015315.)
    Polyvinyl alcohol (PVA) hydrogels, cross-linked with varying concentrations of borax, were studied with Small Angle Neutron Scattering (SANS), X-ray Diffraction (XRD) and Differential Thermal Analysis (DTA). The SANS data ...
  • XAFS as a tool for study of persistent luminescence biomarkers 
    Priolkar, K.R. (Transactions of the Indian Ceramic Society. 76(2); 2017; 85-96.)
    Persistent luminescence or long afterglow or long lasting phosphorescence has attracted a lot of attention because of its varied applications in emergency or safety sign boards, toys and more recently for in vivo imaging ...
  • Phase-separated magnetic ground state in Mn sub(3)Ga sub(0.45)Sn sub(0.55)C 
    Dias, E.T.; Priolkar, K.R.; Nigam, A.K.; Singh, R.; Das, A.; Aquilanti, G. (Physical Review B. 95(14); 2017; ArticleID 144418.)
    The existence of nonergodic ground states is considered as a precursor to a first-order long-range magnetostructural transformation. Mn sub(3)Ga sub(0.45)Sn sub(0.55)C lies compositionally between two compounds, Mn sub(3)GaC ...
