A Parametric Study of the Synthesis of Silica Nanoparticles via Sol-Gel Precipitation Method
In this study, SiO2 nanoparticles were successfully synthesized via sol-gel precipitation method and the effects of different parameters such as temperature, ethanol, ammonia and tetraethylorthosilicate (TEOS) contents based on water were investigated in a systematic way applying Taguchi experimental design method. It was found that, among all the investigated parameters, ethanol as a co-solven...
متن کاملPreparation and Characterization of High Specific Surface Area γ-Alumina Nanoparticles Via Sol-Gel Method
In the present investigation, γ-alumina nanoparticles with particle sizes less than 10 nm, high specific surface area (351 m2/g), high pore volumes and relatively narrow pore sizes distribution was prepared via sol-gel method in presence of aluminum isopropoxide as an aluminum precursor, distilled water, acetic acid as hydrolysis rate controller and tert-butanol as solvent. They had meso ...
متن کاملEnhanced targeted MRI contrast using silica coated magnetite nanoparticles
Introduction MRI is a high spatial resolution non-invasive technique but it has low specificity for targeting explicit pathologies. In an effort to improve specificity, MRI contrast agents with strong paramagnetic properties such as Gadolinium have been developed. However recent reports of suspected deaths associated with gadolinium administration have severely limited their use [1-2]. Iron oxi...
متن کاملPreparation of Silica by Sol-Gel Method Using Formamide
In this work we obtained microporous and mesoporous silica gels by sol-gel processing. Tetraethylortosilicate (TEOS) was used as precursor. Nitric acid and hydrofluoric acid were used as catalysts. In order to study the affect of formamide as drying additive, we used a molar ratio alkoxide/formamide of 1/1. The performance of formamide in obtaining crack-free gels was evaluated through monolith...
