Amine functionalized MCM-41: An active and reusable catalyst for Knoevenagel condensation reaction

Parida, K.M.; Rath, D. (Journal Of Molecular Catalysis A-Chemical, 310(1-2), 2009: 93-100)

This paper reports preparation, characterization of amine modified mesoporous crystalline MCM-41 and its application in Knoevenagel condensation reaction. Amine modified MCM-41 was prepared by cocondensation and post-synthesis ...
A study on extraction of copper using LIX 84-I and LIX 622N

Panigrahi, S.; Parhi, P.K.; Sarangi, K.; Nathsarma, K.C. (Separation And Purification Technology, 70(1), 2009: 58-62)

The bulk sulphide precipitate obtained after addition of Na(2)S to the Fe- and Mn-free leach liquor of manganese nodule was leached with H(2)SO(4) and the leach liquor contained 13 kg/m(3) copper, 15.6 kg/m(3) nickel, 2.6 ...
Phosphotungstic acid promoted zirconia-alumina mixed oxides: A stable and reusable catalysts for epoxidation of trans-stilbene

Parida, K.M.; Mallick, S. (Catalysis Communications, 11(1), 2009: 51-57)

Zirconia-alumina mixed oxide supported phosphotungstic acid catalysts were synthesized and characterized by various techniques. The surface-and bulk properties of the catalysts were examined by Xray diffraction, BET surface ...
Thermal Plasma Processing for the Production of Pig Iron from Various Sources

Jayasankar, K.; Mohapatra, S.; Routray, S.K.; Gumaste, J.L.; Mukherjee, P.S. (High Temperature Materials And Processes, 28(1-2), 2009: 1-8)

Thermal plasma technology is emerging as one of the eco-friendly routes for processing fine wastes from metallurgical and allied industries. In the thermal plasma process, high density of ionic charges makes the uniform ...
Preparation and characterization of alpha-Fe2O3-CeO2 composite

Sahoo, S.K.; Mohapatra, M.; Pandey, B.; Verma, H.C.; Das, R.P.; Anand, S. (Materials Characterization, 60(5), 2009: 425-431)

In our previous study we attempted to see the effect of cerium doping (Ce/Fe ratio 0.015 to 0.074) on goethite matrix and conversion of doped goethite to hematite. In the present communication, nano-structured alpha-Fe2O3-CeO2 ...
Emission of N2O on pulse-rice crop rotation in upland

Ramulu, T.S.; Sahoo, S.K.; Mohapatra, R.K.; Chaudhury, G.R.; Das, S.N. (Atmospheric Environment, 43(12), 2009: 2087-2090)

The Seasonally Integrated Flux (SIF) of N2O emission during pulse cultivation in Rabi season (Season-I: December to April) in rain-fed uplands of Orissa, was found to be 17.7 +/- 0.07, 18.7 +/- 0.16 and 43.3 +/- 0.14 gha(-1) ...
Origin of graphite, and temperature of metamorphism in Precambrian Eastern Ghats Mobile Belt, Orissa, India: A carbon isotope approach

Sanyal, P.; Acharya, B.C.; Bhattacharya, S.K.; Sarkar, A.; Agrawal, S.; Bera, M.K. (Journal Of Asian Earth Sciences, 36(2-3), 2009: 252-260)

The carbon isotope composition of graphite and carbon and oxygen isotope composition of associated calcite from different locations of the Eastern Ghats Mobile Belt (EGMB) of Orissa have been measured in order to understand ...
Acylation of anisole over 12-heteropolyacid of tungsten and molybdenum promoted zirconia

Parida, K.M.; Mallick, S.; Pradhan, G.C. (Journal Of Molecular Catalysis A-Chemical, 297(2), 2009: 93-100)

The liquid-phase acylation of anisole using acetic anhydride was performed over 12 heteropoly acid of tungsten and molybdenum (PWM) modified zirconia (ZPWM). Catalysts with different PWM loadings (3-20 wt.%) were prepared ...
Manganese containing MCM-41: Synthesis, characterization and catalytic activity in the oxidation of ethylbenzene

Parida, K.M.; Dash, S.S. (Journal Of Molecular Catalysis A-Chemical, 306(1-2), 2009: 54-61)

A series of Mn-MCM-41 containing manganese from 2 to 10 wt.% were synthesized by impregnation method using aqueous manganese(II) acetate solution as the precursor. The samples were characterized by X-ray powder diffraction, ...
On the potential of Tephrosia purpurea as anti-Helicobacter pylori agent

Chinniah, A.; Mohapatra, S.; Goswami, S.; Mahapatra, A.; Karl, S.K.; Mallavadhani, U.V.; Das, P.K. (Journal Of Ethnopharmacology, 124(3), 2009: 642-645)

Aim of the study: Since Tephrosia purpurea (Linn.) Pets. (Fabaceae) has traditional use in curing different types of wounds including gastrocluodenal ulcers, it was of interest to evaluate the in vitro anti-Helicobacter ...
