Amine functionalized K10 montmorillonite: a solid acid-base catalyst for the Knoevenagel condensation reaction

Varadwaj, G.B.B.; Rana, S.; Parida, K.M. (Dalton Transactions, 42(14), 2013: 5122-5129)

Different amine functionalized K10 montmorillonites were hydrothermally fabricated by a simple method of treatment of the neat clay with different amine solutions and used as heterogeneous catalysts towards the Knoevenagel ...
Quick photo-Fenton degradation of phenolic compounds by Cu/Al2O3-MCM-41 under visible light irradiation: small particle size, stabilization of copper, easy reducibility of Cu and visible light active material

Pradhan, A.C.; Nanda, B.; Parida, K.M.; Das, M. (Dalton Transactions, 42(2), 2013: 558-566)

The present study reports the photo-Fenton degradation of phenolic compounds (phenol, 2-chloro-4-nitrophenol and 4-chloro-2-nitrophenol) in aqueous solution using mesoporous Cu/Al2O3-MCM-41 nanocomposite as a heterogeneous ...
Effect of strain rate on acoustic emission during tensile deformation of alpha-brass

Pattnaik, A.B.; Jha, B.B.; Sahoo, R. (Materials Science And Technology, 29(3), 2013: 294-299)

In the present investigation, acoustic emission (AE) technique has been used to study the effect of variation in strain rate on AE signals during tensile deformation of alpha-brass. Tensile tests have been carried out at ...
Effect of microstructural degradation on acoustic emission during tensile deformation of 2.25Cr-1Mo steel

Pattnaik, A.B.; Jha, B.B. (Canadian Metallurgical Quarterly, 52(2), 2013: 217-221)

In this paper a systematic study has been undertaken to correlate the microstructural variation with acoustic emission parameters during tensile deformation of 2.25Cr-1Mo steel. Tensile testing of normalised and thermally ...
Experimental study on microstructural variation in near alpha titanium alloy during non-optimal regime of superplastic deformation

Sahoo, R.; Jha, B.B.; Sahoo, T.K. (Materials Science And Technology, 29(7), 2013: 854-860)

Superplasticity is generally achieved in titanium alloys with a fine grained microstructure when deformation is carried out under narrow ranges of strain rate and temperature. Under these conditions, titanium alloys show ...
Deposition of plasma sprayed copper slag coatings on metal substrates

Mantry, Sisir; Behera, D.; Satapathy, A.; Jha, B.B.; Mishra, B.K. (Surface Engineering, 29(3), 2013: 222-227)

Copper slag is a waste product obtained during matte smelting and refining of copper. The present work explores the coating potential of copper slag by plasma spraying. This work shows that copper slag is eminently coatable. ...
Agrigenomics for Microalgal Biofuel Production: An Overview of Various Bioinformatics Resources and Recent Studies to Link OMICS to Bioenergy and Bioeconomy

Misra, N.; Panda, P.K.; Parida, B.K. (Omics-A Journal Of Integrative Biology, 17(11), 2013: 537-549)

Microalgal biofuels offer great promise in contributing to the growing global demand for alternative sources of renewable energy. However, to make algae-based fuels cost competitive with petroleum, lipid production ...
Preliminary investigation into direct reduction of iron in low temperature hydrogen plasma

Rajput, P.; Bhoi, B.; Sahoo, S.; Paramguru, R.K.; Mishra, B.K. (Ironmaking & Steelmaking, 40(1), 2013: 61-68)

There has been an increasing interest in reduction of iron ore by hydrogen. This study deals with the reduction of haematite in a microwave assisted non-thermal hydrogen plasma. The plasma is composed of excited hydrogen ...
In Search of Actionable Targets for Agrigenomics and Microalgal Biofuel Production: Sequence-Structural Diversity Studies on Algal and Higher Plants with a Focus on GPAT Protein

Misra, N.; Panda, P.K. (Omics-A Journal Of Integrative Biology, 17(4), 2013: 173-186)

The triacylglycerol (TAG) pathway provides several targets for genetic engineering to optimize microalgal lipid productivity. GPAT (glycerol-3-phosphate acyltransferase) is a crucial enzyme that catalyzes the initial step ...
Synthesis and Characterization of NanocrystallineMg-7.4%Al Powders Produced by Mechanical Alloying

Chaubey, A.K.; Scudino, S.; Khoshkhoo, M.S.; Prashanth, K.G.; Mukhopadhyay, N.K.; Mishra, B.K.; Eckert, J. (Metals, 3(1), 2013: 58-68)

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 ...
