Dansyl-based fluorescent films prepared by chemical and electrochemical methods: cyclic voltammetry, afm and spectrofluorimetry characterization

Characterization of Pure and Antimony Doped SnO2 Thin Films Prepared by the Sol-Gel Technique

Pure and antimony doped SnO2 thin films have been prepared by the sol-gel dip coating technique on glass substrate using starting material SnCl2.2H2O as a host and SbCl3 as a dopant. Our experimental results revealed that, the quality of the coated films on the glass depends on process parameters. The effect of annealing temperature, dipping numbe...

Synthesis of Au Nanoparticles by Thermal, Sonochemical and Electrochemical Methods: Optimization and Characterization

The present study concentrates on the synthesis of Au nanoparticles (AuNPs) using aqueous solution of Polyvinylpyrrolidone (PVP) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. The PVP has been used as a reducing agent and acts as a stabilizer for Au nano particles that obtained as principal product. In all synthesis procedures, the active radi...

Antioxidant Properties of Ajwain using Square wave, Cyclic voltammetry methods and DPPH method

Ajwain is one of the medicinal plants, which the highest composition is thymol, as a strong antioxidant respect to the obtained chromatograms of GC/MS. The antioxidant activity of the Ajwain is measured by square wave voltammetry method and cyclic voltammetry method and 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) method in at the specific concentrations of 1%, 1.5%, 2% and 2.5% and constant pH. The r...

Growth and Characterization of Thin MoS2 Films by Low- Temperature Chemical Bath Deposition Method

Transition metal dichalcogenide (TMDC) materials are very important inelectronic and optical integrated circuits and their growth is of great importance in thisfield. In this paper we present growth and fabrication of MoS2 (Molibdan DiSulfide)thin films by chemical bath method (CBD). The CBD method of growth makes itpossible to simply grow large area scale of the thin la...
