Cobalt ferrite aerogels by epoxide sol-gel addition: Efficient catalysts for the hydrolysis of 4-nitrophenyl phosphate

Akl J.; Ghaddar T.; Ghanem A.; El-Rassy H. (AMSTERDAMPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2009)

Porous cobalt ferrite aerogel catalysts were obtained by 1,2-epoxide sol-gel process and investigated in the hydrolysis of 4-nitrophenyl phosphate. These materials were synthesized by reacting cobalt and iron salts with ...
Electric resistivity and magnetic susceptibility studies of Tl-1223 substituted by cobalt

Isber S.; Awad R.; Abou-Aly A.I.; Tabbal M.; Kaouar J.M. (BRISTOLDIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2005)

Bulk superconductor samples of type TlBa2Ca2(Cu 3-xCox)O9-δ with 0 ≤ x ≤ 0.6 were prepared by a single-step solid-state reaction. The prepared samples were characterized by powder x-ray diffraction and the superconductivity ...
Reaction-diffusion based co-synthesis of stable α- and β-cobalt hydroxide in bio-organic gels

Al-Ghoul M.; El-Rassy H.; Coradin T.; Mokalled T. (AMSTERDAMPO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2010)

We report the preparation, dynamics of formation and extensive characterization of a stable two-phase system of crystalline α- and β-Co(OH)2. The method is based on the reaction and diffusion of hydroxide ions into a ...
