Effect of planetary ball milling on phase transformation of a silica-rich iron ore

Sakthivel, R.; Jayasankar, K.; Das, S.K.; Das, B.; Mishra, B.K. (Powder Technology, 208(3), 2011: 747-751)

The phase transformation of a silica-rich iron ore during planetary milling has been studied. A mixture of silica-rich low grade iron ore and iron powder (4.75 wt.%) was subjected to high energy ball milling and the resulting ...
Optimization of variables in grinding brass particles for paint and pigment industry

Badjena, S.K.; Mishra, B.K. (Powder Technology, 214(3), 2011: 349-355)

Flaky metal powders commonly used as paint and pigments, are generally produced by grinding in ball mills or vibration mills. The key to good quality powder production is to optimize the processing parameters. In the present ...
Root growth of TiO2 nanorods by sputtering

Pradhan, S.S.; Pradhan, Siddhartha Kumar; Bagchi, S.; Barhai, P.K. (Journal Of Crystal Growth, 330(1), 2011: 1-4)

The growth of TiO2 nanorods by a simple sputtering method is reported. Here we show that by sputtering of Ti target in argon-oxygen plasma it is possible to grow rutile core and anatase shell heterostructure TiO2 nanorods ...
Alteration in metal ion induced fluorescence signaling responses of benzofurazan appended acyclic amino-receptor through its structural modification

Bag, B.; Pal, A.; Biswal, B. (Journal Of Luminescence, 131(6), 2011: 1121-1130)

Fluorescent signaling probes 3 and 4 in the integrated 'fluorophore-receptor' format have been synthesized by derivatization of 'amino-alkyl-amino' based receptors with 7-chloro-4-nitrobenz-2-oxa-1,3-diazole fluorophore ...
Fluoride removal studies from contaminated ground water by using bauxite

Sujana, M.G.; Anand, S. (Desalination, 267(2-3), 2011: 222-227)

The present study explores the feasibility of utilizing bauxite for fluoride removal from synthetic and natural fluoride bearing groundwater samples of Orissa, India. Adsorption experiments with respect to variation in ...
Lipid Composition and Antibacterial Screening of Lipophilic Extract of a Marine Sponge Haliclona sp Collected from the Bay of Bengal (Orissa Coast), India

Mishra, P.M.; Sree, A. (Asian Journal Of Chemistry, 23(10), 2011: 4321-4324)

The fatty acid composition as well as volatiles and antibacterial screening of lipophilic extract of the sponge Haliclona sp. were analyzed. The fatty acids are characterized by linear saturated, short chain unsaturated, ...
Separation of Copper from Chalcopyrite-Ammoniacal Leach Liquor Containing Copper, Zinc, and Magnesium by Supported Liquid Membrane

Adebayo, A.O.; Sarangi, K. (Chemical And Biochemical Engineering Quarterly, 25(3), 2011: 309-316)

A low grade chalcopyrite ore was leached with H(2)O(2)/(NH(4))(2)SO(4) and the leach liquor contained 42.96 mol m(-3) copper, 3.52 mol m(-3) zinc and 11.23 mol m(-3) magnesium. From this leach liquor separation of copper ...
Separation of Co (II) and Ni (II) from the mixed sulphate/chloride solution using NaPC-88A

Parhi, P.K.; Padhan, E.; Palai, A.K.; Sarangi, K.; Nathsarma, K.C.; Park, K.H. (Desalination, 267(2-3), 2011: 201-208)

The mixed sulphate/chloride leach liquor of manganese nodules bearing 11.8 iron, 24.8 copper, 0.23 zinc, 3.8 cobalt, 35.2 nickel, 176.3 chloride and 48.9 sulphate in g/L was processed for separation of Fe. Cu and Zn and ...
Erosion Behavior of Glass-epoxy Composites Filled with SiC from Bamboo Leaf

Mantry, Sisir; Mohapatra, S.; Mohapatra, S.; Singh, S.K.; Manda, A.; Satapathy, A. (International Polymer Processing, 26(2), 2011: 164-172)

The present article reports the processing, mechanical characterization and solid particle erosion response of a new class of multi phase composites consisting of epoxy resin reinforced with E-glass fiber and SiC particulates. ...
In Situ Synthesis of Entrapped Silver Nanoparticles by a Fungus-Penicillium purpurogenum

Pradhan, Nilotpala; Nayak, R.R.; Pradhan, A.K.; Sukla, L.B.; Mishra, B.K. (Nanoscience And Nanotechnology Letters, 3(5), 2011: 659-665)

Intracellular silver nanoparticles are produced by exposing silver nitrate to a fungus-Penicillium purpurogenum. The formation of silver nanoparticles is greatly influenced by the secretion of proteins and more specifically ...
