Phase Transformation of TiO2 from Anatase to Rutile by Thermal Annealing and Swift Heavy Ion Irradiation

Rath, H.; Anand, S.; Mohapatra, M.; Dash, P.; Som, T.; Singh, U.P.; Mishra, N.C.; Kanjilal, D.; Avasthi, D.K. (Mesoscopic, Nanoscopic, And Macroscopic Materials, 1063, 2008: 250-+)

In die present study, we probe into the phase transition from anatase to rutile in natiocrystalline thin films under thermal annealing and swift heavy ion (SHI) irradiation. TiO2 thin films were prepared through chemical ...
Effect of milling time on the rheology of highly loaded aqueous-fused silica slurry

Mohanta, K.; Bhargava, P. (Journal Of The American Ceramic Society, 91(2), 2008: 640-643)

The effects of milling time on the rheological behavior of 70-vol% loaded fused silica slurries were studied. A transition from shear thickening to shear thinning behavior was observed with milling time. Slurry viscosity ...
Nano-star formation in Al-doped ZnO thin film deposited by dip-dry method and its characterization using atomic force microscopy, electron probe microscopy, photo luminescence and laser Raman spectroscopy

Behera, D.; Acharya, B.S. (Journal Of Luminescence, 128(10), 2008: 1577-1586)

Zinc oxide doped with Al (AZO) thin films were prepared on borosilicate glass substrates by dip and dry technique using sodium zincate bath. Effects of doping on the structural and optical properties of ZnO film were ...
Preparation, characterization, and photocatalytic activity of sulfate-modified titania for degradation of methyl orange under visible light

Parida, K.M.; Sahu, N.; Biswal, N.R.; Naik, B.; Pradhan, A.C. (Journal Of Colloid And Interface Science, 318(2), 2008: 231-237)

Hydrated titania was prepared by a sol-gel method, taking tetraisopropyl orthotitanate as starting material, and then promoted with different weight percentages of sulfate by an incipient wetness impregnation method. The ...
Biodegradable polymers. XI. Spectral, thermal, morphological, and biodegradability properties of environment-friendly green plastics of soy protein modified with thiosemicarbazide

Nanda, P.K.; Rao, K.K.; Nayak, P.L. (Journal Of Applied Polymer Science, 103(5), 2007: 3134-3142)

The demand for biodegradable polymers produced from renewable natural resources continues to grow as environmental concerns increase. Biodegradable plastics derived from agricultural feedstock are a new generation of ...
Effect of organized assemblies. Part 4. Formulation of highly concentrated coal-water slurry using a natural surfactant

Das, D.; Panigrahi, S.; Misra, P.K.; Nayak, A. (Energy & Fuels, 22(3), 2008: 1865-1872)

Coal-water slurry has received considerable research nowadays due to its ability in substituting energy sources. The present work reports the formulation of highly concentrated coal-water slurry using a natural occurring ...
Morphology evolution of Sb2S3 under hydrothermal conditions: Flowerlike structure to nanorods

Ota, J.; Roy, P.; Srivastava, S.K.; Nayak, B.B.; Saxena, A.K. (Crystal Growth & Design, 8(6), 2008: 2019-2023)

Nanorods of Sb2S3 have been synthesized by a Surfactant assisted hydrothermal method. The formation of nanorods through flowerlike morphology with an intermediate straw tide like structure has been depicted by scanning ...
Preparation of Non Oxide Ceramics in Thermal Plasma

Singh, S.K. (Mesoscopic, Nanoscopic, And Macroscopic Materials, 1063, 2008: 183-189)

Titanium carbonitride (TiCN) and ultrafine SiC have been prepared in extended arc thermal plasma reactors using graphite electrodes. The prepared materials have been characterized by a variety of analytical methods. It has ...
Sintering Of MgO and TiO2 Doped Al-Zr Oxides Composites by Extended Arc Thermal Plasma

Ray, M.; Pradhan, S.K.; Dash, S.; Mishra, D.K.; Singh, S.K.; Sahu, D.; Roul, B.K. (Mesoscopic, Nanoscopic, And Macroscopic Materials, 1063, 2008: 230-+)

MgO and TiO2 doped Al-Zr oxide composites of Zr0.95Al1.05MgxO with x=0,0.01,...,0.05,0.75,1 and Zr-0.95-Al-1.05-Ti-z-O with z=0, 0.025,..., 1 were sintered to high density by both DC thermal plasma assisted rapid sintering ...
Adsorption kinetics of natural dissolved organic matter and its impact on arsenic(V) leachability from arsenic-loaded ferrihydrite and Al-ferrihydrite

Mohapatra, D.; Mishra, D.; Rout, M.; Chaudhury, G.R. (Journal Of Environmental Science And Health Part A-Toxic/hazardous Substances & Environmental Engineering, 42(1), 2007: 81-88)

The present work was broadly divided into two parts: first, the efficiency of synthetically prepared ferrihydrite and Al-ferrihydrite to adsorb dissolved organic matter (DOM) was tested as a function of time, pH and ionic ...
