Effect of Cu/In molar ratio on the microstructural and optical properties of microcrystalline CuInS2 prepared by solvothermal route

Das, K.; Panda, S.K.; Gorai, S.; Mishra, Pratima Kumari; Chaudhuri, S. (Materials Research Bulletin, 43(10), 2008: 2742-2750)

Synthesis and characterization of CuInS2 powder sample prepared by a simple and convenient solvothermal method is reported. The influence of the variation of Cu/In molar ratio from 0.69 to 1.25 on the particle morphology, ...
Optimization of electrophoretic deposition of alumina onto steel substrates from its suspension in iso-propanol using statistical design of experiments

Mohanty, G.; Besra, L.; Bliattacharjee, S.; Singh, B.P. (Materials Research Bulletin, 43(7), 2008: 1814-1828)

Statistical design of experiments was used to investigate the effect the process parameters on electrophoretic deposition (EPD) of alumina onto steel substrates from its suspension in iso-propanol. The process parameters ...
Synthesis, characterization and dielectric properties of europium-doped barium titanate nanopowders

Rath, M.K.; Pradhan, G.K.; Pandey, B.; Verma, H.C.; Roul, B.K.; Anand, S. (Materials Letters, 62(14), 2008: 2136-2139)

Europium-doped cubic barium titanate (BT) nanocrystals with % [Eu/Ti] mol ratio varying from 0.05 to 0.25 were prepared through hydrothermal route. The nano nature of these powders was confirmed by XRD and TEM studies. ...
Thermal plasma assisted rapid sintering of MgO-doped Al-Zr oxide composites

Ray, M.; Sahu, D.R.; Singh, S.K.; Verma, S.; Roul, B.K. (Materials Chemistry And Physics, 107(2-3), 2008: 435-443)

MgO-doped Al-Zr oxide composites of Zr0.95Al1.05MgxO with x = 0, 0.01,..., 0.05, 0.75, 1 were sintered to high density by both dc thermal plasma assisted rapid sintering as well as conventional sintering. It was observed ...
Critical fluidization velocities and maximum bed pressure drops of homogeneous binary mixture of irregular particles in gas-solid tapered fluidized beds

Sau, D.C.; Mohanty, Swati; Biswal, K.C. (Powder Technology, 186(3), 2008: 241-246)

Recently, tapered fluidized bed has become more attractive because of the problems associated with conventional (cylindrical) beds like fluidization of widely distributed particles, entrainment or particles and limitation ...
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)
