Preparation and Evaluation of NiFe204 and CuFe204 Nanoeatalysts by Combination of Sol- Gel Auto-Combustion Method and Irradiation Technique
The dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. Cu and Ni Unites nanocatalyst powders sithcomposition of Caned], and NiFe204 were synthesized by a sol-gel auto catalnic combustion process. Themolar ratio between metal ions and urea was 11.2. The sob gel process was done at 8...
متن کاملImprovement of anti-cancer drug efficacy via thermosensitive hydrogel in peritoneal carcinomatosis in gastric cancer
Peritoneal carcinomatosis (PC) of gastric origin has a poor prognosis with short survival due to lack of effective therapeutic modalities. Here, we evaluated the therapeutic efficacy of an injectable thermosensitive poly (organophosphazene) (PPZ) hydrogel with docetaxel (DTX-gel) to develop an effective therapeutic agent for patient with PC. Three days after inoculation of highly metastatic 44A...
متن کاملSynthesis and characterization of nanocrystalline spinel Zinc ferrite prepared by sol-gel auto-combustion technique
Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning electron microsco...
متن کاملEvaluation of Photocatalytic Activity of Fe Doped TiO2 Thin Film Prepared by sol-gel hot dip-coating
The application of Fe–TiO2 photocatalysis using sol–gel method by hot–dipping technique was investigated. Then, the influences of fabrication parameters, molar ratios of Fe to TiO2, the sol temperature, poly ethylene glycol (PEG) content and the number of dipping cycles on the photocatalytic activity in visible light region were mainly studied. The experimental results revealed the sample with ...
