Facile Synthesis of Bi2O3/TiO2-xNx and its Direct Solar-Light-Driven Photocatalytic Selective Hydroxylation of Phenol

Naik, B.; Parida, K.M.; Behera, G.C. (Chemcatchem, 3(2), 2011: 311-318)

Mesoporous Bi2O3/TiO2-xNx nanocomposites (BiNT) have been synthesized by using a template-free homogeneous coprecipitation technique. X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission electron ...
Probing the effect of nitrogen gas on electrical conduction phenomena of ZnO and Cu-doped ZnO thin films prepared by spray pyrolysis

Behera, D.; Panigrahi, J.; Acharya, B.S. (Ionics, 17(8), 2011: 741-749)

Zinc oxide (ZnO) and Cu-doped ZnO (CZO) thin films were prepared on borosilicate glass substrates by spray pyrolysis technique. The X-ray diffraction study revealed that Cu doping caused a reduction in crystallite size. ...
Facile Synthesis of Dodecatungstophosphoric Acid @ TiO2 Pillared Montmorillonite and Its Effectual Exploitation Towards Solvent Free Esterification of Acetic Acid with n-Butanol

Varadwaj, G.B.B.; Parida, K.M. (Catalysis Letters, 141(10), 2011: 1476-1483)

An acid activated montmorillonite, treated with organic cationic surfactant, i.e. cetyltrimethylammonium bromide (CTAB), was used as a template to prepare TiO2 pillared montmorillonite taking titanium ethoxide as titania ...
Preparation and characterization of molybdenum trioxide from spent hydrodesulfurization catalyst

Dash, B.; Bhattacharya, I.N.; Ramanamurthy, B.V.; Paramguru, R.K. (Korean Journal Of Chemical Engineering, 28(7), 2011: 1546-1549)

An approach to produce molybdenum trioxide from spent hydrodesulfurization (HDS) catalyst, obtained from a petroleum refinery, is presented here. The spent catalyst was devolatilized at 600 degrees C so as to make it free ...
Efficient Synthesis and Characterization of Nanostructured TiC Powder by Reaction Milling

Chaira, D.; Sangal, S.; Mishra, B.K. (Transactions Of The Indian Institute Of Metals, 64(6), 2011: 549-554)

Nanocrystalline TiC powder is synthesized from corresponding elemental constituents by reaction milling in a dual drive planetary mill. The study shows nanocrystalline TiC powder could be produced from Ti + graphite and ...
Ambient temperature synthesis of nanorod 6-line ferrihydrite and its cation sorption behavior

Mohapatra, M.; Padhi, T.; Dash, T.; Singh, P.; Anand, S.; Mishra, B.K. (Toxicological And Environmental Chemistry, 93(5), 2011: 844-859)

Nano-structured rod-shaped particles of 6-line ferrihydrite were synthesized at ambient temperature under controlled conditions. The phase formation was confirmed through X-ray diffraction (XRD). Shape and size of the ...
Fe(III)-salim anchored MCM-41: synthesis, characterization and catalytic activity towards liquid phase cyclohexane oxidation

Singha, S.; Parida, K.M.; Dash, A.C. (Journal Of Porous Materials, 18(6), 2011: 707-714)

A novel organic-inorganic hybrid catalyst [MCM-41-Fe-III(salim)] was synthesized by covalently anchoring Fe-III(salim) complex into the pore channels of MCM-41. The material was synthesized by the co-condensation of ...
Microbial Beneficiation of Salem Iron Ore Using Penicillium purpurogenum

Mishra, M.; Pradhan, M.; Sukla, L.B.; Mishra, B.K. (Metallurgical And Materials Transactions B-Process Metallurgy And Materials Processing Science, 42(1), 2011: 13-19)

High alumina and silica content in the iron ore affects coke rate, reducibility, and productivity in a blast furnace. Iron ore is being beneficiated all around the world to meet the quality requirement of iron and steel ...
Green synthesis of silver nanoparticle by Penicillium purpurogenum NPMF: the process and optimization

Nayak, R.R.; Pradhan, Nilotpala; Behera, D.; Pradhan, K.M.; Mishra, S.; Sukla, L.B.; Mishra, B.K. (Journal Of Nanoparticle Research, 13(8), 2011: 3129-3137)

An eco-friendly microbial method for synthesis of silver colloid solution with antimicrobial activity is developed using a fungal strain of Penicillium purpurogenum NPMF. It is observed that increase in concentration of ...
Acoustic emission studies during the high temperature oxidation of 2.25Cr-1Mo steel at 1173 K

Jha, B.B.; Mishra, B.K.; Mohapatra, B.K.; Ojha, S.N. (Materials At High Temperatures, 27(4), 2011: 301-311)

Breakaway oxidation behaviour of 2.25Cr-1Mo steel has been studied at 1173 K, using the acoustic emission (AE) technique. AE parameters, i.e. events, ring down counts (RDC), rise time (RT) and event duration (ED) show ...
