Nanosilica/PMMA composites obtained by the modification of silica nanoparticles in a supercritical carbon dioxide-ethanol mixture
(Springer, 2009)
Nanosilica/poly(methyl methacrylate) (PMMA) composites are used to improve the mechanical properties of neat PMMA polymer. In order to obtain superior mechanical properties, it is essential to achieve good bonding between ...
Mechanochemically induced amorphous/crystalline phase transition in the Bi4Ti3O12 compound
(Elsevier, 2009)
Concurrent milling of Bi4Ti3O12 was carried out in a planetary ball mill with hardened-steel 13 or 6 mm diameter balls with a goal to investigate how the system responds to the constrains imposed by milling. Milling intensity ...
TiO2 films prepared by ultrasonic spray pyrolysis of nanosize precursor
(Materials Letters, 2002)
A methodology for the preparation of the TiO2 films, based on the process of ultrasonic spray pyrolysis and usage of TiO2 nanoparticles, with the mean diameter of 45 Angstrom as a precursor, was developed. The X-ray ...
Combined FTIR and SEM-EDS study of Bi2O3 doped ZnO-SnO2 ceramics
(Wiley, 2008)
The effects of Bi2O3 addition on the phase composition, microstructure and optical properties of ZnO-SnO2 ceramics were investigated. Starting powders of ZnO and SnO2 were mixed in the molar ratio 2:1. After adding Bi2O3 ...
The influence of urea on the formation process of BiPbSrCaCuO superconducting ceramics synthesized by spray pyrolysis method
(Elsevier, 2000)
The influence of urea on the formation process in the Bi-Pb-Sr-Ca-Cu-O system, as well as, on the final high Tc. phase content and morphology of the powders obtained by spray pyrolysis method was studied. The process ...
Structural and magnetic characterization of LiMn1.825Cr0.175O4 spinel obtained by ultrasonic spray pyrolysis
(Materials Research Bulletin, 2007)
Quaternary spinel oxide LiMn1.825Cr0.175O4 Powder was synthesized by using an ultrasonic spray pyrolysis method, without additional annealing. The crystal structure of the as-prepared powder was revealed by X-ray powder ...
Hydrothermal synthesis of NaxFexTi2-xO4 from natural ilmenite sand: A CaFe2O4 structure type compound
(Elsevier, 2008)
NaxFexTi2-xO4 a compound from the CaFe2O4 structure type group, was obtained via hydrothermal route at a temperature lower than 200 {ring operator}C for the first time. Natural ilmenite sand, a low cost reagent, was used ...
Polypyrrole as possible electrode materials for the aqueous-based rechargeable zinc batteries
(Elsevier, 2008)
Polypyrrole (PPy) thin film electrode was galvanostatically synthesized and characterized in 0.1 M HCl on graphite electrode as cathode materials for the aqueous-based rechargeable zinc batteries. The charge/discharge ...
Reaction sintering of the 2ZnO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 minutes. ...
Infrared reflection spectroscopy of Zn2SnO4 thin films deposited on silica substrate by radio frequency magnetron sputtering
(Elsevier, 2008)
Single-phase zinc-stannate thin films of different thickness values were prepared by radio frequency magnetron sputtering on a silica substrate. Rietveld analysis of X-ray diffraction data confirmed that the films had an ...
