    Nanocrystalline Mg-7.4%Al powder was prepared by mechanical alloying using a high-energy mill. The evolution of the various phases and their microstructure, including size and morphology of the powder particles in the ...
  • Active Control of Transformer Noise by Using Power Line Signal as Reference 
    Das, D.P.; Moreau, D.J.; Cazzolato, B. (Proceedings Of The 2013 Ieee 8th Conference On Industrial Electronics And Applications (Iciea), 2013: 953-956)
    The hum noise generated from the distribution transformers is annoying and is significant when the transformer is installed near the residential area. This hum noise consists of harmonics of 100 Hz, when the power line ...
  • Statistical Modeling Studies of Iron Recovery from Red Mud Using Thermal Plasma 
    Rath, S.S.; Pany, A.; Jayasankar, K.; Mitra, A.K.; Kumar, C.S.; Mukherjee, P.S.; Mishra, B.K. (Plasma Science & Technology, 15(5), 2013: 459-464)
    Optimization studies of plasma smelting of red mud were carried out. Reduction of the dried red mud fines was done in an extended arc plasma reactor to recover the pig iron. Lime grit and low ash metallurgical (LAM) coke ...
  • Oxidation-Precipitation of Cobalt (II) in Aqueous Sulphate Solution Using Sodium Persulfate 
    Kim, H.H.; Park, K.H.; Nam, C.W.; Parhi, P.K. (Korean Journal Of Metals And Materials, 51(12), 2013: 865-871)
    Oxidation and precipitation of Co(II) in sulphate solution using Na2S2O8 as an oxidant was studied. The main factors affecting the oxidation of Co(Il), the reaction time, temperature, pH of solution, agitation speed and ...
  • Preliminary investigations on alkali leaching kinetics of red sediment ilmenite slag 
    Laxmi, T.; Mohapatra, R.; Rao, R.B. (Korean Journal Of Chemical Engineering, 30(1), 2013: 123-130)
    The present paper deals with soda ash roasting of red sediment ilmenite (47.03% TiO2) and leaching of obtained titanium rich slag with hydrochloric acid for preparation of synthetic rutile. The experimental conditions used ...
  • Maximizing Biomass Productivity and CO2 Biofixation of Microalga, Scenedesmus sp by Using Sodium Hydroxide 
    Nayak, M.; Rath, S.S.; Thirunavoukkarasu, M.; Panda, P.K.; Mishra, B.K.; Mohanty, R.C. (Journal Of Microbiology And Biotechnology, 23(9), 2013: 1260-1268)
    A series of experiments were carried out with three native strains of microalgae to measure growth rates, biomass, and lipid productivities. Scenedesmus sp. IMMTCC-6 had better biomass growth rate and higher lipid production. ...
  • Characterization and optical properties of Eu-doped cubic nano ceria synthesized by using the co-precipitation-hydrothermal route 
    Sahoo, S.K.; Mohapatra, M.; Anand, S. (Journal Of The Korean Physical Society, 62(2), 2013: 297-304)
    A series of nano ceria samples containing 0 to 2 mol% europium were synthesized following the co-precipitation hydrothermal technique. The X-ray diffraction patterns showed peaks corresponding to the fluorite structure of ...
  • Aqueous processing of nickel spent catalyst for a value added product 
    Sheik, A.R.; Ghosh, M.K.; Sanjay, K.; Subbaiah, T.; Mishra, B.K.; Baba, A.A. (Korean Journal Of Chemical Engineering, 30(2), 2013: 400-404)
    Nickel was recovered from a fertilizer industry spent catalyst by leaching with nitric acid followed by nickel hydroxide precipitation. The optimization of temperature, initial acid concentration and particle size for ...
  • Dissolution kinetics of nickel from spent catalyst in nitric acid medium 
    Sheik, A.R.; Ghosh, M.K.; Sanjay, K.; Subbaiah, T.; Mishra, B.K. (Journal Of The Taiwan Institute Of Chemical Engineers, 44(1), 2013: 34-39)
    In this study, the kinetics of nitric acid leaching of a spent NiO-Al2O3 catalyst was investigated. Influence of leaching parameters such as temperature (60-90 degrees C), acid concentration (1.5-5 M) and average particle ...
  • Bioleaching of copper from pre and post thermally activated low grade chalcopyrite contained ball mill spillage 
    Panda, S.; Pradhan, Nilotpala; Mohapatra, U.; Panda, S.K.; Rath, S.S.; Rao, D.S.; Nayak, B.D.; Sukla, L.B.; Mishra, B.K. (Frontiers Of Environmental Science & Engineering, 7(2), 2013: 281-293)
    Bioleaching of a low grade chalcopyrite (ball mill spillage material) was tested for copper recovery in shake flasks. The original samples (as received) were thermally activated (600A degrees C, 30 min) to notice the change ...
