An aqueous sol-gel synthesis of chromium (III) doped mesoporous titanium dioxide for visible light photocatalysis

Jaimy, K B; Ghosh, S K; Sankar, S; Warrier, K G K (Elsevier, 2011)

Nanoparticles of titanium dioxide doped with Cr (3+) ions have been prepared through an aqueous sol-gel method. The mesoporous nature of both pure and Cr(3+) doped TiO(2) powders, with specific surface area of 7.4 and 6.6 ...
Critical behaviour and magnetocaloric effect of nano crystalline La0.67Ca0.33Mn1 xFexO3 (x ¼ 0.05, 0.2) synthesized by nebulized spray pyrolysis

Nisha, P; Savitha Pillai, S; Darbandi, A; Manoj Raama Varma; Suresh, K G; Hahn, H (Elsevier, 2012-09-14)

The structure, critical exponents and magnetocaloric effect (MCE) of Nebulized Spray Pyrolysis (NSP)synthesized nano crystalline La0.67Ca0.33Mn1 xFexO3 (x ¼ 0.05, 0.2) were investigated. The Reitveld refinement of XRD ...
Electrical transport properties of manganese containing pyrochlore type semiconducting oxides using impedance analyses

Sumi, S; Prabhakar Rao, P; Mahesh, S K; Peter Koshy (Elsevier, 2012)

A new series of manganese containing pyrochlore type semiconducting oxides CaCe1 xMnxSnNbO7 d(x = 0, 0.2, 0.4 and 0.6) have been synthesized to study the effect of Mn substitution on the structure,microstructure and ...
High-surface-area alumina-silica nanocatalysts prepared by a hybrid sol-gel route using a boehmite precursor

Padmaja, P N; Moothetty, P; Wunderlich, W; Berry, F J; Mortimer, M; Creamer, N J; Warrier, K G K (Wiley -Blackwell, 2010)

High-surface-area alumina-silica mixed oxide (Al(2)O(3):SiO(2)) nanocatalysts have been prepared by a hybrid sol-gel method using boehmite (synthesized from aluminum nitrate) as the source of alumina and tetraethyl ...
Ionic conductivity in new perovskite type oxides: NaAZrMO(6) (A = Ca or Sr; M = Nb or Ta)

Deepthi, N R; Ravindran Nair, K; Prabhakar Rao, P; Sibi, K S; Peter Koshy; Vaidyan, V K (Elsevier, 2008)

New oxides of the type, NaAZrMO(6) (M = Ca or Sr; M = Nb or Ta), have been prepared by the solid-state reaction technique. Phase identification by powder X-ray diffraction (XRD) shows that NaCaZrMO6 has orthorhombic ...
Microwave dielectric properties of Ca2+xLa8-x (SiO4)(6-x)(PO4)(x)O-2 solid solution

Dhanesh, T; Sebastian, M T (Wiley, 2011)

The present communication investigates the microwave dielectric properties of Ca2+xLa8-x(SiO4)(6-x)(PO4)(x)O-2 (x = 0, 2, 4, and 6) ceramics. The ceramics have been prepared by the conventional solid state ceramic route. ...

Prabhakar Rao, P; Ravindran Nair, K; Peter Koshy; Vaidyan, V K (Springer, 2006)

New dielectric materials based on complex oxides containing rare earth tantalates: Ca3RE3Ti7Ta2O26.5 (RE = Pr, Sm, Gd, Dy or Y) have been investigated for their structure, FT-IR spectra, microstructure and dielectric ...
Tape casting and dielectric properties of sr2znsi2o7-based ceramic-glass composite for low-temperature co-fired ceramics applications

Tony Joseph; Sebastian, M T; Jantunen, H; Jacob, M; Sreemoolanadhan, H (Wiley, 2011)

The Sr2ZnSi2O7 ceramics sintered at 1475 degrees C has epsilon(r) = 8.5, Q (u) x f = 105,000 GHz (at 12.63 GHz), and tau(f) = -51.5 ppm/degrees C. The sintering temperature of Sr2ZnSi2O7 has been lowered to 875 degrees C ...
Y-Doped Bi2MoO6 yellow pigments for the coloration of plastics

Kumari, L S; Gayathri, T H; Sameera, S F; Prabhakar Rao, P (Wiley, 2011)

Y-doped Bi2MoO6 was synthesized by the conventional ceramic method in order to assess its potential as ceramic pigment. The optimized colorants were characterized for their structural as well as optical properties. The ...
