  • Magnetic interactions in the martensitic phase of Mn rich Ni-Mn-In shape memory alloys 
    Lobo, D.N.; Dwivedi, S.; daSilva, C.A.; Moreno, N.O.; Priolkar, K.R.; Nigam, A.K. (Journal of Applied Physics. 114(17); 2013; Article No. 173910.)
    The magnetic properties of Mn(2) Ni (1+ x )In(1- x ) (x = 0.5, 0.6, 0.7) and Mn(2- y) Ni (1.6+ y)In(0.4) (y = -0.08, -0.04, 0.04, 0.08) shape memory alloys have been studied. Magnetic interactions in the martensitic phase ...
  • Quantum phases and phase transitions of frustrated hard-core bosons on a triangular ladder 
    Mishra, T.; Pai, R.V.; Mukerjee, S.; Paramekanti, A. (Physical Review B. 87(17); 2013; Article ID. 174504.)
    Kinetically frustrated bosons at half filling in the presence of a competing nearest-neighbor repulsion support a wide supersolid regime on the two-dimensional triangular lattice. We study this model on a two-leg ladder ...
  • Diffusion of water in bentonite clay: Neutron scattering study 
    Sharma, V.K.; Prabhudesai, S.A.; Raut-Dessai, R.; Desa, J.A.E.; Mitra, S. (AIP Conf. Proc. 2013; 918-919.)
    Diffusion of water confined in natural bentonite clay is studied using the quasi-elastic neutron scattering (QENS) technique. X-ray diffraction shows a well-defined crystalline structure of the clay with an interlayer ...
  • Role of manganese in red long-lasting phosphorescence of manganese-doped diopside for in vivo imaging 
    Lecointre, A.; Bessiere, A.; Priolkar, K.R.; Gourier, D.; Wallez, G.; Viana, B. (Materials Research Bulletin. 48(5); 2013; 1898-1905.)
    Materials with red long-lasting phosphorescence, such as MnII-doped diopsides, can be used for small animal in vivo imaging. CaMgSi2O6:Mn powders with various amounts of Mn were prepared by sol-gel to investigate their ...
  • Effect of sintering on magnetic properties of Ni0.55Zn0.45Fe2O4 
    Kothawale, M.M.; Tangsali, R.B.; Naik, G.K.; Budkuley, J.S. (Journal of Superconductivity and Novel Magnetism. 26(11); 2013; 3293-3298.)
    Bulk Ni0.55Zn0.45Fe2O4 samples were obtained by sintering their nanopowder at 1100 degrees C, 1200 degrees C, and 1300 degrees C. Improvement in crystallinity on sintering was identified from increase in intensity of the ...
  • Infrared properties of 'lead free' thick film NTC thermo-resistive sensor based on the mixture of spinel material and RuO2 
    Jagtap, S.; Rane, S.; Gosavic, S.; Mulik, U.; Amalnerkar, D. (Sensors and Actuators A-Physical. 197; 2013; 166-170.)
    Thermistors fit into the category of infra-red detectors commonly called thermal detectors which operate through the heating effects of the incident radiation. This thermal detector converts the infra-red radiation into ...
  • Evaluation of ZnO nanoparticles and study of ZnO-TiO2 composites for lead free humidity sensors 
    Jagtap, S.; Priolkar, K.R. (Sensors and Actuators B-Chemical. 183; 2013; 411-418.)
    This paper deals with synthesis of ZnO nanoparticles through two different baths: Ammonium zincate bath and sodium zincate bath. Synthesized ZnO nanoparticles were characterized by means of TG/DTA, FTIR, UV-vis, XRD, and ...
  • Effects of pressure and temperature on pore structure of ceramic synthesized from rice husk: A small angle neutron scattering investigation 
    Dessai, R.R.; Desa, J.A.E.; Sen, D.; Mazumder, S. (Journal of Alloys and Compounds. 564; 2013; 125-129.)
    Ceramic powder has been synthesized from rice husk as the source of silica. In order to probe the evolution of its hierarchical mesoscopic and microscopic porous structure, the ceramic powder was compacted at different ...
  • Diffusion of water in bentonite clay 
    Dessai, R.R.; Sharma, V.K.; Prabhudesai, S.A.; Mitra, S.; Desa, J.A.E.; Mukhopadhyay, R. (Journal of The Physical Society of Japan. 82; 2013; SA008-.)
    Diffusion of water confined in sodium bentonite clay is studied using the quasi-elastic neutron scattering (QENS) technique. Hydration of bentonite clay is characterized by several methods including X-ray diffraction and ...
  • Red persistent luminescence in MgGa(2)O(4):Cr3+; a new phosphor for in vivo imaging 
    Basavaraju, N.; Sharma, S.; Bessiere, A.; Viana, B.; Gourier, D.; Priolkar, K.R. (Journal of Physics D-Applied Physics. 46(37); 2013; Article ID: 375401.)
    A new red-emitting long-lasting phosphorescence (LLP) material useful as biomarker for small animal in vivo imaging is presented. X-ray irradiated MgGa(2)O(4):Cr3+ is shown to be a suitable persistent phosphor emitting in ...
