In this work firstly CoFe2O4 nanoparticles were synthesized via a hydrothermal method. The temperature, surfactant and capping agent effects on the size of CoFe2O4 nanoparticles were investigated. 2-hydroxyacetophenone used as a good capping agent to produce cubic-like nanostructure. When SDBS used as surfactant, particles had spherical morphology. Nanoparticle was studied by scanning electron ...

Background:Characterizing the structure and function of superoxide dismutase (SOD), as an antioxidant enzyme providing opportunities for its application in food supplements. Objectives: In this study, the features of the Manganese-SOD of Lactococcus lactis (SDLL), subsp. cremoris MG1363, as probiotic bacteria, were determined on the ...

Yttrium tungstate precursors with novel 3D hierarchical architectures assembled from nanosheet building blocks were successfully synthesized by a hydrothermal method with the assistance of sodium dodecyl benzenesulfonate (SDBS). After calcination, the precursors were easily converted to Y(2)(WO(4))(3) without an obvious change in morphology. The as-prepared precursors and Y(2)(WO(4))(3) were ch...

A review is presented on the properties, origin and evolutionary links of hot subluminous stars which are generally believed to be extreme Horizontal Branch stars or closely related objects. They exist both in the disk and halo populations (globular clusters) of the Galaxy. Amongst the field stars a large fraction of sdBs are found to reside in close binaries. The companions are predominantly w...

This article reports a novel synthetic methodology for preparing Bi2Te3 nanotubes as well tailoring their size and aspect ratio, which provides strong potential interest in the field of thermoelectrics. were synthesized via 1-dodecanethiol (DDT) assisted aqueous two-steps synthesis. One its main advantages is to be easily scalable because it carried under mild experimental conditions. The compl...
