Iron chelating drugs can impede the rapid reproduction of tumor cells. Among these drugs, deferasirox (DEF) have shown antitumor properties and therefore been selected for this study. The aim of this study was preparation and characterization of the bifunctional polymeric nanoparticles (NPs) by targeting moieties which is applied in cancer. Therefore, DEF NPs were fabricated by exploiting of PLGA-PEG-FOL conjugate and com Read More

In this study, Fe doped barium aluminate nano powder has been synthesized via homogeneous precipitation method and was investigated for its activity on the epoxidation chalcone with hydrogen peroxide as a pure oxidant. The obtained samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and Energy-dispersive X-ray spectroscopy (EDAX). The average particle siz Read More

Urea intercalated layered material nanohybrid formulations based on two types of layered clays, layered double hydroxides and montmorillonite were developed for agricultural applications as slow release nitrogen plant nutrient formulations. The resulting nanohybrids were prepared by the intercalation of urea between the nanolayers of clay matrixes. The successful intercalation of the guest urea molecule was confirmed us Read More

In this study, sulfonated poly ethylene terephthalate (SPET) nonwoven membrane for heavy metal ion filtration was prepared by electrospining with different conditions and then simulated by wastewater containing metal ion as an aqueous solution. Commonly used for the exclusion of metal ions from wastewater, the ionic interaction between negatively charged matrices and positively charged metal ions has been utilized. The co Read More

In this study the effect of annealing at 400oC and gamma irradiation at 30 kGy doses with the rate of 2.4 Gy/s as post treatments on optical properties and dimension of Ag nanoclusters was investigated. Ag nanoclusters were formed by ion-exchange process during which SLS substrates immersed in to the AgNO3 salt bath at 400°C. Grazing incidence x-ray diffraction analysis demonstrated the presence of Ag on Ag-ion e Read More

Ab initio calculations of ZnO nanowires (NW) were performed using density functional theory within LDA-1/2, to account for the excited states energies. The effects of hydrogenpassivated and non-passivated nanowires in a range of diameters were studied. For passivated cases it was obtained a band gap of 5.5 eV for the thinnest wire (∼0.6 nm thick) and 4.0 eV for the thickest NW (∼1.6 nm) (and similar to bulk for the Read More

Engineered nanomaterials in the 21st century have revolutionized all dimensions of life and Titanium di oxide nanoparticles are one such important materials, which are being increasingly used for a variety of clinical, cosmoceutical, pharmaceutical, optical and other commercial applications. Their versatile applications are mainly due to the large surface-to-volume ratio and unique physico-chemical, mechanical and electrical Read More
