The gravimetric analysis of electrodeposited nickel is demonstrated using electrochemical quartz crystal microbalance (EQCM) where the nickel coatings come from a solution of the metal chloride salt separately in either a1choline chloride: 2 ethylene glycol (ethaline) or 1 choline chloride: 2 urea (reline) based ionic liquid. The possibility of adapting the Quartz Crystal Microbalance EQCM (which measures the mass attached to the electrode) to probe kinetics of electrochemically-driven solid state phase transformations has been explored in a Ni electrodeposition in absence and presence of complexing agents ethylene diamine en and acetylacetonate acac from both electrolytes ethaline and reline. The study shows that the current efficiency and the rate of deposition of nickel coatings obtained from ethaline and reline baths in absence of brighteners en and acac are different, and the addition of en and acac to both ionic liquid solutions results in a significant decrease current. And the associated growth rate will also be decreased, suggesting that the en acac stops the formation and growth of Ni nuclei. This suggests that the mechanism of growth is changed.

In recent years Copper-64 in the chemical form of copper chloride ([64Cu]CuCl2) has been identified as a potential agent for PET imaging and radionuclide therapy. The aim of this research was to determine the biodistribution and the labeling of radio nanoparticle with 64CuCl2, the nanoparticles Cu(acac)2/F-TiO2 were mixed with 64CuCl2 (20-37 MBq), then the final solution was used to injected healthy Wistar rats to probe the absorption of nanoparticle inside tissue trough of the groups OH that are formed during the functionalization of the Cu(acac)2/F-TiO2. The “in vivo” evaluation after realize the images study in micro PET equipment, uptake of the radio-nanoparticle was observed in the digestive system in the healthy Wistar rats.
