The Scientific and Technological Qualification refers to the necessary adaptation to the development of new radiopharmaceuticals, specifically in the phase of scheduling until pilot, within the required quality standards. In addition, one must consider safety issues for manipulation of high radioactive activities, compatible with the scale of industrial production, making it possible to c…

The present project aims to investigate a metallic oxide with a perovskite structure of the BaTiO3 type and its doping by the Cs element, in order to analyze its instability when exposed to different doses of radiation. Different synthesis methods of this structure will be employed, namely solid-state synthesis and hydrothermal synthesis, and then compared to determine the one with the be…
This project aims at fabrication of biocompatible magnetic nanoparticles on cobalt or nickel ferrite basis with a potential to adapt them for radiotherapy among other medical applications. Organic coating is expected to provide the biocompatibility of (Ni,Co)Fe2O4, whereas doping elements, RE=Sm, Eu, Gd, Er, are believed to enhance radiotherapeutic efficiency. We intend to adapt synthesis…
The main purpose of this project is the atomic scale investigation of nanostructuredmaterials of semiconductor oxides by means of experimental measurements of hyperfineinteractions (HFI) and first-principles calculations. Pure or mainly metal doped semiconductoroxides present very interesting properties which make them good candidates for technologicalapplications which can have significa…

We propose a continuation of the study of intrinsic effects in vanadium oxides. The mechanism of temperature-induced reduction in V2O5 is to be probed by TDPAC spectroscopy with 111mCd probes implanted at ISOLDE. We expect to extract information on the dynamics of oxygen vacancies and identify all the reduction products. In addition, a study of cadmium meta- and pyrovanadates is to be per…
Hyperfine interactions probed at different nuclei of implanted ions (acting as dopants) in vanadiumoxides (VO2 and V2O5) will be measured in order to understand, along with first-principlescalculations, the doping phenomenology at the nanoscopic scale and its consequence on the electric and magnetic properties of the host oxides. Vanadium oxides are particularly attractive due to the phas…
Strongly Correlation system has very interesting properties, in particular, Ce-based intermetallic compounds. In recent decades this type of systems has been studied by different experimental techniques and theoretical models. The objective of this project is to carry out a systematic study of the structural and magnetic properties as well as the hyperfine parameters in intermetallic com…
