Preparation and Characterization of ZrO2/TiO2 Nanocomposite under Ultrasonic Irradiation by Sol-gel Route
TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...

متن کاملUltrasonic Irradiation Assisted Enantioselective Synthesis of Alzheimer’s Disease Drug Rivastigmine Tartrate by Using Nanocatalyst
A highly efficient and convenient procedure for the enantioselective synthesis of (S)-Rivastigmine tartrate, a cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer’s disease, is accomplished by the treatment of versatile, readily accessible N-Ethyl-N-methyl carbamoyl chloride with 3-hydroxyacetophenone under ultrasonic irradiation in presence of nano-K2CO3 were repo...
متن کاملPreparation of Deferasirox in nano-scale by ultrasonic irradiation and optimization the amount and reaction time parameters
This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...
