The impacts of zinc oxide nanoparticles on embryonic development following oocyte stage exposure are unknown and the underlying mechanisms are sparsely understood. In the current investigation, intact nanoparticles were detected in ovarian tissue in vivo and cultured cells in vitro under zinc oxide nanoparticles treatment. Zinc oxide nanoparticles exposure during the oocyte stage inhibited embr...

Abstract Residual fragments can remain after kidney stone extraction which may necessitate another intervention. Magnetic nanoparticles (MNP) be applied due to their properties of being able bind residual and extracted by an external magnetic field. Calcium oxalate crystals have been synthesized, characterized used for binding separation studies. The is validated simulation experimentally. MNP ...

Previous measurements show that calcium manganese oxide nanoparticles are better water oxidation catalysts than binary manganese oxides (Mn3O4, Mn2O3, and MnO2). The probable reasons for such enhancement involve a combination of factors: The calcium manganese oxide materials have a layered structure with considerable thermodynamic stability and a high surface area, their low surface energy sugg...

BACKGROUND Accumulating evidence indicates that iron oxide nanoparticles modulate immune responses, and induce oxidative stress in macrophages. It was recently reported that iron oxide nanoparticles attenuated antigen-specific immunity in vivo, though the underlying mechanism remains elusive. The present study investigates the direct effect of iron oxide nanoparticles on antigen-specific cytoki...

Cobalt oxide (Co3O4) nanoparticles were successfully prepared by thermal decomposition of cobalt hydroxide synthesized from cobalt acetate, ammonium hydroxide and 10% glycerol. The cobalt oxide nanoparticles calcined at 450 °C were characterized by using XRD. The XRD confirms the crystallinity and crystal structure of the sample. It also shows that the diffraction peak are broadened which revea...

There is a considerable interest in new technologies that allow noninvasive imaging of physiological parameters in living systems, especially in the neuroscience. Magnetic resonance imaging (MRI) is a very powerful tool for neuroimaging, because it can image the tissue noninvasively, in depth, at a good spatial (~100 pm) and temporal (~1s) resolution. In order to study neural activity at a cell...

Abstract In the construction industry, cement-based materials as aggregate binding agent are still widely used. Due to environmental concern, researchers working create eco-friendly cement-free materials. Calcium oxide (CaO) is a reactive earth metal that could serve potential activator for ground granulated blast furnace slag (GGBFS). this experimental study, mortar was produced by using GGBFS...

objective(s): so far, extensive research has been conducted on the preparation and characterization of nano ceramics based on ca-si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (ma). the aim of this study was the preparation of akermanite nano powder by mechanical activation method and bioact...
