    The structural and magnetic interactions in stoichiometric (Mn sub(3)SnC), carbon deficient (Mn sub(3)SnC sub(0.8)) and tin deficient (Mn sub(3)Sn sub(0.85)C) antiperovskite compounds are studied using X-ray absorption ...
  • Importance of site occupancy and absence of strain glassy phase in Ni sub(2-x)Fe sub(x)Mn sub(1.5)In sub(0.5) 
    Nevgi, R.; Das, G.; Acet, M.; Priolkar, K.R. (Journal of Alloys and Compounds. 797; 2019; 995-1001.)
    Martensitic transition temperature steadily decreases in Ni sub(2-x)Fe sub(x)Mn sub(1.5)In sub(0.5) and is completely suppressed at x = 0.2. Despite suppression of martensitic transition, Ni sub(1.8)Fe sub(0.2)Mn sub(1.5)In ...
  • Ultra-low temperature CO oxidation activity of octahedral site cobalt species in Co sub(3) O sub(4) based catalysts: Unravelling the origin of unique catalytic property 
    Baidya, T.; Murayama, T.; Nellaiappan, S.; Katiyar, N.; Bera, P.; Safonova, O.; Lin, M.; Priolkar, K.R.; Kundu, S.; Rao, B.S.; Steiger, P.; Sharma, S.; Biswas, K.; Pradhan, S.; Nakka, L.; Malviya, K.D.; Haruta, M. (Journal of Physical Chemistry C. 123(32); 2019; 19557-19571.)
    Co sub(3) O sub(4) with spinel structure shows CO oxidation activity at very low temperature under dry condition. This study aims at finding the origin of the unique catalytic activity of Co species in Co sub(3) O sub(4) ...
  • Relaxor like colossal dielectric constant in CoWO sub(4) and CoWO sub(4) /PbWO sub(4) nanocomposites 
    Jeyakanthan, M.; UmaSubramanian; Tangsali, R.B.; Jose, R.; Saravanan, K.V. (Journal of Materials Science: Materials in Electronics. 30(15); 2019; 14657-14668.)
    Dielectric constant epsilon' and dielectric loss epsilon" were measured in the frequency range of 500 Hz-3 MHz from room temperature (RT) to 350 degrees C for CoWO sub(4) and CoWO sub(4)/PbWO sub(4) nanocomposites sintered ...
  • Edge consecutive gracefulness of a graph 
    Pereira, J.; Singh, T.; Arumugam, S. (Discrete Applied Mathematics. 280; 2020; 214-220.)
    We present several basic results on ecg and use this parameter to prove that any connected graph G can be embedded as an induced subgraph of a graceful graph and as an induced subgraph of an eulerian graceful graph.
  • Important influence of Bi deficiency on the conducting property of Na sub(0.5)Bi sub(0.5) TiO sub(3) perovskite oxide 
    Santhoshkumar, B.; LokeswaraRao, P.; Ramanathan, K.V.; Bera, A.K.; Pahari, B. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030570.)
    Recently it has been reported that low levels of Bi nonstoichiometry (only plus or minus 1 atomic percent) in the nominal starting composition of Na sub(0.5) Bi sub(0.5) TiO sub(3) (NBT) ceramics can lead to dramatic changes ...
  • Mossbauer study and Curie temperature configuration on sintering Nano-Ni-Zn Ferrite powder 
    Kothawale, M.M.; Tangsali, R.B.; Meena, S.S.; Prasad, N.K.; Gangwar, A. (Journal of Superconductivity and Novel Magnetism. 32(7); 2019; 2141-2147.)
    Variations of Curie temperature and strength of magnetic phases with sintering temperature and Ni concentration is investigated in the present work. The AC susceptibility studies show a decrease in Curie temperature (TC) ...
  • Influence of praseodymium on alumino-germanate glasses containing Nd and La inclusions 
    Soares, B.P.; Desa, J.A.E.; Krishna, P.S.R. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030247.)
    Oxides of La, Nd and Pr have been included both singly and as pairs in Alumino-Germanate glasses at molar percentages varying from 5 percent to 10 percent. The glass transition temperatures were found by differential thermal ...
  • Spin-1 bosons in optical superlattice 
    Gaonker, C.G.F.; Alavani, B.K.; Das, A.; Pai, R.V. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030016.)
    In this paper, we analyze superfluid, insulator and various magnetic phases of ultracold spin-1 bosonic atoms in two-dimensional optical superlattices. Our studies have been performed using Cluster Mean Field Theory. ...
  • Effect of iron and sodium inclusion on some properties of silicate glass 
    Nayak, M.T.; Desa, J.A.E.; Babu, P.D. (AIP Conference Proceedings. 2115(1); 2019; ArticleID_030224.)
    Sodium silicate glasses with a fixed molar percentage of iron and varying percentages of sodium alkali have been synthesized by the method of melt quenching in air. The variation of glass transition temperatures Tg in this ...
