CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration .The optimum condition ...

Introduction: External radiotherapy is the most common method of radiotherapy which the most important problem associated with is that there is no difference between healthy and tumor tissues in dose absorption. One way to differentiate the dose sensitivity is to use metal-based nanoparticles. Bismuth oxide nanoparticles are good candidates for cancer radiotherapy. In this study, we investigate...

In this study, the effects and interactions of reaction time and capping agent assistance during sol-gel synthesis of magnesium substituted hydroxyapatite nanopowder (MgHA) on hydroxyapatite (HA) to β-tricalcium phosphate (β-TCP) ratio, Ca/P ratio and mean crystallite size was examined experimentally as well as through statistical analysis. MgHA nanopowders were synthesized by sol-gel technique...

in this study, we investigated the antifungal effects of silver nanoparticles (ag-nps) on candida albicans (atcc 5027), saccharomyces cerevisiae (atcc 5027). investigating method by using minimum inhibitory concentration (mic) technique, some of drugs including amphotericin b, fluconazole and synthesized ag-nps have been obtained on the fungi and the changes on membrane reactions of yeasts have...

The synthesis of semiconductor nanoparticles is an expanding research area due to the potential applications in the development of nanotechnologies. Especially, biosynthesized nanoparticles have become an important branch of nanotechnology. In the present work, we describe a low-cost and simple procedure for biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using Pyrus Pyrifolia leaf extract. ...

Background: Recently, applications of albumin nanoparticles as drug delivery carriers have increased. Most toxicology studies have shown that surface chemistry and size of nanoparticles play an important role in biocompatibility and toxicity. Objective: The effect of desolvating agents with different chemical properties on the size of synthesized HSA NPs was investigated. Materials and Method...

Cancer is a leading cause of death worldwide and sustained focus is on the discovery and development of newer and better tolerated anticancer drugs, especially from plants. In the present study, a simple, eco-friendly, and inexpensive approach was followed for the synthesis of zinc oxide nanoparticles (ZnO NPs) using the aqueous leaf extract of Eclipta prostrata. The synthesized ZnO NPs were ch...

06 Transparent conductive oxides (TCOs) are a technologically important class of materials. [ 1 ] Herein we describe a facile, universal, and green ‘one-pot’ approach to produce stable dispersions comprising TCO nanoparticles (NPs) such as SnO 2 , In 2 O 3 , ATO ( ≡ SnO 2 :Sb), ITO ( ≡ In 2 O 3 :Sn), and ZTO ( ≡ SnO 2 :Zn). The synthesis begins by etching the bare metal powder precursors (Sn, I...
