The electrochemical stability of antimony in a water stable room temperature ionic liquid composed of 1:5 mole ratio of hydrated ammonium aluminum sulfate -urea ionic liquid at 30 °C was investigated at 0.3 M antimony (III) chloride solution. The electroplating of antimony at -0.8 V showed black coating on copper substrate. The stability of this cation in this ionic liquid was studied by cyclovoltammogram. The electrodeposition was followed up by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Energy Dispersive X-ray analysis (EDAX) and X-ray diffraction (XRD).The nanoparticles size of the metal were in the range of less than 500nm.
New tin complexes were made from the reaction of various tin reagents with atenolol. These complexes were mixed with PVC to produce the stabilized polymeric films. The stability of the films was evaluated using UV/Vis absorption spectroscopy and field emission scanning electron microscopy. The rate of photodecomposition constant have been calculated for PVC films as a method for evaluating the efficiency of atenolol-tin complexes 1–4 that used as a photostabilizers after 300 hour of irradiation. The results have showed that the additives had reduced the rate of photodecomposition constant of PVC films significantly with comparison to PVC (blank). The rate constant of photodecomposition (kd) value for PVC films was higher than that after addition of atenolol tin complexes as photostabilizers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
