Removal of methylene blue using biosynthesized silver nanoparticles
In recent decades, the focus of science and industry has been concentrated on production of metalnanoparticles (NPs). In this study, the biosynthesis of silver NPs by using Tragopogon buphthalmoides(Tragopogon b.) plant was investigated. Various effective parameters on the synthesis such as pH, extractvolume, concentration of silver nitrate, temperature and reaction time were ...
متن کاملPhotocatalytic Coating Using Titania-Silica Core/Shell Nanoparticles
The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...

متن کاملSynthesis of Silica Coated Magnetic Nanoparticles
In this research controlled coating of magnetite (Fe3O4) nanoparticles with SiO2 was investigated. The Fe3O4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to Stober method. Effects of tetra ethyl ortho silicate (TEOS) concentration and ethanol to TEOS on the coating thickness were inves...
متن کاملMethylene blue-containing silica-coated magnetic particles: a potential magnetic carrier for photodynamic therapy.
We present the preparation and characterization of methylene blue-containing silica-coated magnetic particles. The entrapment of methylene blue (MB), a photodynamic therapy drug under study in our group, in the silica matrix took place during the growth of a silica layer over a magnetic core composed of magnetite nanoparticles. The resulting material was characterized by transmission electron m...
