Optical property modification of ZnO: Effect of 1.2 MeV Ar irradiation

Chattopadhyay, S.; Dutta, S.; Pandit, P.; Jana, D.; Chattopadhyay, S.; Sarkar, A.; Kumar, P.; Kanjilal, D.; Mishra, D.K.; Ray, S.K. (Physica Status Solidi C: Current Topics In Solid State Physics, Vol 8, No 2, 8(2), 2011)

We report a systematic study on 1.2 MeV Ar8+ irradiated ZnO by X-ray diffraction (XRD), room temperature photoluminescence (PL) and ultraviolet-visible (UV-Vis) absorption measurements. ZnO retains its wurtzite crystal ...
Cobalt-Bearing Grunerite in the Metamorphosed Banded Iron Formation in Orissa, India

Nayak, P.K.; Mohapatra, B.K.; Singh, P.P.; Martha, R.K. (Resource Geology, 61(3), 2011: 281-289)

Banded iron formation (BIF) comprising high grade iron ore are exposed in Gorumahisani-Sulaipat-Badampahar belt in the east of North Orissa Craton, India. The ores are multiply deformed and metamorphosed to amphibolite ...
Adsorption of Cadmium from Aqueous Solution by Ficus religiosa Leaf Powder and Characterization of Loaded Biosorbent

Rao, K.S.; Anand, S.; Venkateswarlu, P. (Clean-Soil Air Water, 39(4), 2011: 384-391)

The present investigation evaluates the adsorption effectiveness of Cd(II) ions on Ficus religiosa leaf powder (FRL). The experimental parameters chosen included time, pH, particle size, temperature, adsorbate, anion, and ...
Novel-Type Inorganic Foams from Preceramic Polymers with Embedded Titania Nanoparticles for Photo-Catalytic Applications

Bhattacharjee, S.; Das, P.R.; Ohl, C.; Wilker, V.; Kappa, M.; Scheffler, F.; Scheffler, M. (Advanced Engineering Materials, 13(11), 2011: 996-1001)

Photocatalytic active silica-based foams were prepared by embedding nanotitania (anatase) into a self-foaming glass particle-loaded preceramic polymer and then thermally converting it in air into a silica-based material. ...
WASTE TO WEALTH: PRODUCTION OF Fe-Ni FROM LATERITIC ORE/CHROMITE OVERBURDEN OF SUKINDA DEPOSIT IN ORISSA, INDIA

Bhoi, B.; Mishra, C.R.; Mishra, H.P. (2nd International Symposium On High-Temperature Metallurgical Processing, 2011: 363-370)

the Sukinda Valley of Orissa, India, the total quantity of nickel ore reserves comprising of both lateritic and chromite over burden(COB) have been estimated at around 231 million tonnes containing 0.3 to 0.9% Ni. While ...
Facile Synthesis of Bi2O3/TiO2-xNx and its Direct Solar-Light-Driven Photocatalytic Selective Hydroxylation of Phenol

Naik, B.; Parida, K.M.; Behera, G.C. (Chemcatchem, 3(2), 2011: 311-318)

Mesoporous Bi2O3/TiO2-xNx nanocomposites (BiNT) have been synthesized by using a template-free homogeneous coprecipitation technique. X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission electron ...
Probing the effect of nitrogen gas on electrical conduction phenomena of ZnO and Cu-doped ZnO thin films prepared by spray pyrolysis

Behera, D.; Panigrahi, J.; Acharya, B.S. (Ionics, 17(8), 2011: 741-749)

Zinc oxide (ZnO) and Cu-doped ZnO (CZO) thin films were prepared on borosilicate glass substrates by spray pyrolysis technique. The X-ray diffraction study revealed that Cu doping caused a reduction in crystallite size. ...
Facile Synthesis of Dodecatungstophosphoric Acid @ TiO2 Pillared Montmorillonite and Its Effectual Exploitation Towards Solvent Free Esterification of Acetic Acid with n-Butanol

Varadwaj, G.B.B.; Parida, K.M. (Catalysis Letters, 141(10), 2011: 1476-1483)

An acid activated montmorillonite, treated with organic cationic surfactant, i.e. cetyltrimethylammonium bromide (CTAB), was used as a template to prepare TiO2 pillared montmorillonite taking titanium ethoxide as titania ...
Preparation and characterization of molybdenum trioxide from spent hydrodesulfurization catalyst

Dash, B.; Bhattacharya, I.N.; Ramanamurthy, B.V.; Paramguru, R.K. (Korean Journal Of Chemical Engineering, 28(7), 2011: 1546-1549)

An approach to produce molybdenum trioxide from spent hydrodesulfurization (HDS) catalyst, obtained from a petroleum refinery, is presented here. The spent catalyst was devolatilized at 600 degrees C so as to make it free ...
Efficient Synthesis and Characterization of Nanostructured TiC Powder by Reaction Milling

Chaira, D.; Sangal, S.; Mishra, B.K. (Transactions Of The Indian Institute Of Metals, 64(6), 2011: 549-554)

Nanocrystalline TiC powder is synthesized from corresponding elemental constituents by reaction milling in a dual drive planetary mill. The study shows nanocrystalline TiC powder could be produced from Ti + graphite and ...
