  • Processing of solutions containing nickel and ammonium sulphate through solvent extraction using PC-88A 
    Reddy, B.R.; Parija, C.; Sarma, P.V.R.B. (Hydrometallurgy, 53(1), 1999: 11-17)
    A process was developed to obtain a concentrated nickel sulphate:solution from a nickel-containing: cobalt raffinate using PC-88A as the extractant. More than 99% nickel extraction was achieved in three stages with I hi ...
  • Diamond and diamond-like-carbon growth on Si (100) by hot filament-assisted RF plasma CVD 
    Roul, B.K.; Nayak, B.B.; Mishra, Pratima Kumari; Mohanty, B.C. (Journal Of Materials Synthesis And Processing, 7(5), 1999: 281-288)
    Diamond and diamond-like carbon (DLC) crystallites can be grown on a Si (100) substrate by hot filament-assisted RF plasma CVD in a low-vacuum (2-Torr) environment from C2H2 without using hydrogen. The deposition was carried ...
  • The new sponge resources of Orissa coast 
    Bapuji, M.; Sree, A.; Mishra, S.; Vimala, A.; Sahu, S.K.; Choudhury, S.; Thomas, P.A. (Current Science, 77(2), 1999: 220-222)
  • Effects of perfluorocarboxylic acids during zinc electrowinning from acidic sulphate solutions 
    Tripathy, B.C.; Das, S.C.; Singh, P.; Hefter, G.T. (Bulletin Of Electrochemistry, 15(9-10), 1999: 340-342)
    In the present study the effects of perfluoro surfactants like perfluorobutyric acid (PFBA), tridecafluoroheptanoic acid (TDFHA) and pentadecafluoroctanoic acid (PDFOA) on zinc electrowinning from acidic sulphate solutions ...
  • Smelting reduction studies: Scope and limitations 
    Jouhari, A.K.; Galgali, R.K.; Ray, H.S. (Icarism '99: Proceedings Of The International Conference On Alternative Routes Of Iron And Steelmaking, 99(3), 1999: 173-184)
    It is well accepted that the blast furnace will continue as the main route for iron-making for many more years. However, its limitations have motivated researchers to look for alternative routes, particularly, those where ...
  • Somaclonal variation in cell suspension culture-derived regenerants of Cymbopogon martinii (Roxb.) Wats var. motia 
    Patniak, J.; Sahoo, S.; Debata, B.K. (Plant Breeding, 118(4), 1999: 351-354)
    Plants regenerated from cell suspension cultures of palmarosa grass, Cymbopogon martinii (Roxb.) Wats, were analysed for somaclonal variation in five clonal generations. A wide range of variation in important quantitative ...
  • A study on the preparation of TiC reinforced cast iron composites by plasma smelting of ilmenite ore 
    Galgali, R.K.; Ray, H.S.; Chakrabarti, A.K. (International Journal Of Cast Metals Research, 12(1), 1999: 41-48)
    TiC reinforced cast iron composites have been prepared by plasma smelting of ilmenite ore in a bed of steel scrap. The influence of magnesia and zircon coating on smelting hearth on microstructure of composites have been ...
  • Magnetic properties of topochemically sintered barium hexaferrite 
    Gumaste, J.L.; Ray, H.S.; Godkhindi, M.M.; Mukunda, P.G. (Journal Of The American Ceramic Society, 82(11), 1999: 3269-3271)
    This communication describes the method of topochemical reaction sintering for the production of barium hexaferrite. Topochemical reaction sintering overcomes crucial process steps that are used in the conventional wet ...
  • Mass transfer conditions in an electrochemical cell in the presence of turbulence promoters 
    Subbaiah, T.; Venkateswarlu, P.; Das, S.C.; Das, R.P.; Raju, G.J.V.J. (Plating And Surface Finishing, 86(1), 1999: 94-98)
    The presence of turbulence promoters in an electrochemical cell increases the intensity of local turbulence, which enhances the limiting current density and, consequently, mass transfer coefficients. The regularity of their ...
  • Microstructure-dependent coercivity in monodispersed hematite particles 
    Rath, C.; Sahu, K.K.; Kulkarni, S.D.; Anand, S.; Date, S.K.; Das, R.P.; Mishra, N.C. (Applied Physics Letters, 75(26), 1999: 4171-4173)
    Microstructure and magnetic properties of monodispersed pseudocubic and trapezoidal particles with varying sizes prepared through the hydrothermal precipitation route are reported. The coercivity for trapezoidal particles ...
