Ce-doped LCMO CMR manganites: a consequence of enhanced T-c and T-IM

Mishra, D.K.; Sahu, D.R.; Mishra, Pratima Kumari; Singh, S.K.; Mohapatra, B.K.; Roul, B.K. (Bulletin Of Materials Science, 34(7), 2011: 1501-1506)

A series of Ce-doped (1-20 mol%) La0.67Ca0.33MnO3 (LCMO) sintered (1400 degrees C) ceramic samples were prepared by the solid-state reaction route. The significant enhancement of metal insulator transition temperature (T-IM ...
Studies on the effect of flocculant adsorption on the dewatering of iron ore tailings

Dash, M.; Dwari, R.K.; Biswal, S.K.; Reddy, P.S.R.; Chattopadhyay, P.; Mishra, B.K. (Chemical Engineering Journal, 173(2), 2011: 318-325)

The adsorption characteristics of polyacrylamide polymer on iron ore tailings have been studied to understand the mechanism of adsorption. Adsorptions of both the anionic and non-ionic flocculants were analyzed using ...
A fascinating Suzuki homo-coupling reaction over anchored gold Schiff base complexes on mesoporous host

Parida, K.M.; Singha, S.; Sahoo, P.C.; Sahu, S. (Journal Of Molecular Catalysis A-Chemical, 342-43, 2011: 11-17)

We present a study of the use of chloro-functionalized mesoporous silicas as supports for immobilization of Au(III) Schiff base complex, and use of this composite material as heterogeneous catalyst for homocoupling of aryl ...
Role of Ag ions on the structural evolution of nano ZnO clusters synthesized through ultrasonication and their optical properties

Sahu, D.; Acharya, B.S.; Panda, A.K. (Ultrasonics Sonochemistry, 18(2), 2011: 601-607)

ZnO powder doped with 0.84 at wt.% of silver has been synthesized through continuous and pulsed mode sonication method. The particle size was found to be 57(+/- 1) nm and 44(+/- 1) nm for continuous and pulsed mode powder, ...
The Mosquitocidal Activity of Methanolic Extracts of Lantana cramera Root and Anacardium occidentale Leaf: Role of Glutathione S-Transferase in Insecticide Resistance

Tripathy, A.; Samanta, L.; Das, S.; Parida, S.K.; Marai, N.; Hazra, R.K.; Mallavdani, U.V.; Kar, S.K.; Mahapatra, N. (Journal Of Medical Entomology, 48(2), 2011: 291-295)

Larvicidal activity of methanolic plant extracts of Lantana cramera (P1) root and Anacardium occidentale (P2) leaf was investigated against the larvae of the three mosquito species (Culex quinquefasciatus, Anopheles ...
In vitro bioactivity and phytochemical screening of Suaeda maritima (Dumort): A mangrove associate from Bhitarkanika, India

Patra, J.K.; Dhal, N.K.; Thatoi, H.N. (Asian Pacific Journal Of Tropical Medicine, 4(9), 2011: 727-734)

Objective: To investigate the in vitro antioxidant and antimicrobial activities along with phytochemical screening of organic and aqueous extracts of leaf and stem of Suaeda maritima (Dumort) a mangrove associate from ...
EFFECTIVE COMPOSITION OF HIGH CONCENTRATION FLY ASH-BOTTOM ASH MIXTURE SLURRY FOR EFFICIENT DISPOSAL THROUGH PIPELINES

Senapati, P.K.; Mishra, B.K.; Sahu, A.; Kumar, V. (Applied Rheology, 21(2), 2011)

The composition of high concentration ash slurry requires careful selection of particle size distribution (PSD) to achieve the required rheological properties for efficient disposal through pipelines. In the present study, ...
High temperature nitriding of grey cast iron substrates in arc plasma heated furnace

Nayak, B.B.; Kar, O.P.N.; Behera, D.; Mishra, B.K. (Surface Engineering, 27(2), 2011: 99-107)

Grey cast iron substrates were case nitrided at 1000-1100 degrees C by varying several process parameters such as nitriding time, flowrate of N(2) and nitriding gas configuration. Ar and N(2) were mixed with N(2) to change ...
Correlation between properties of zirconia mullite and Y2O3 stabilised zirconia mullite derived by various processing techniques

Prusty, S.; Mishra, D.K.; Mohapatra, B.K.; Singh, S.K. (Advances In Applied Ceramics, 110(6), 2011: 360-366)

Zirconia mullite (MUZ) and Y2O3-MUZ composites were synthesised by plasma melting, plasma sintering and conventional sintering techniques. Mixtures of tetragonal and cubic phases have been observed in all the processed ...
Synthesis, characterization and photoluminescence study of modified titania

Behera, D.; Bag, B.; Sakthivel, R. (Indian Journal Of Pure & Applied Physics, 49(11), 2011: 754-758)

The modified titania has been prepared by nitrogen doping and dispersion of nano-gold particles. They were characterized by using X-ray diffractometer, UV-visible spectrophotometer, BET surface area analyzer, laser Raman ...
