Nanoparticles of La1-xSrxMnO3 compounds
(2002-12-01)
A nanoparticles of La1-xSrxMnO3 were synthesized using homogenous coprecipitation method. The precipate was washed with water and dried at 80 °C. The samples were characterized by X-ray powder diffraction, transmission ...
Study of ITO@PMMA composites by transmission electron microscopy
(2011-10-03)
ITO nanowires were synthesized by carbothermal reduction process, using a co-evaporation method, and have controlled size, shape, and chemical composition. The electrical measurements of nanowires showed they have a ...
The effect of ionic strength on the structural organization of dioctadecyldimethylammonium bromide in aqueous solution
(Springer, 2004-01-01)
High-curvature and stabilized vesicles of dioctadecyldimethylammonium bromide (DODABr) can be formed spontaneously in aqueous electrolytic solution. It is shown by cryo-transmission electron microscopy that 5.0 mM DODABr ...
Yttrium iron garnet heterocoagulated by silica
(2002-09-01)
Coated purpose of homogeneous distribution as a second phase is introduced in magnetic systems. Yttrium iron garnet (YIG) shows special interest as magnetic dye, microwave absorber, and magnetic fluids when heterocoagulated ...
Defect-induced photoluminescence of powdered silica glass
(2008-03-27)
Visible photoluminescence was generated in standard soda-lime-silica glass powder, mechanically milled in a high-energy attrition mill. The broad emission band maximum shows a linear dependence on the exciting wavelength, ...
Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
Influence of oxygen atmosphere on LiNbO3 thin films prepared by Pechini process
(2004-07-27)
Thin films of lithium niobate were deposited on the Pt/Ti/SiO2 (111) substrates by the polymeric precursor method (Pechini process). Annealing in static air and oxygen atmosphere was performed at 500°C for 3 hours. The ...
Analysis of the nucleolar cycle in the seminiferous epithelium of rodents
(2007-12-28)
The nucleolus is a subcompartment of the nucleus and the site of ribosome biogenesis. During the mitotic and meiotic cell cycles, a disorganization and later reorganization of the nucleolar material occur, an event called ...
