Congratulations Dr. Natalia Chamorro, new SUMAN-UAB graduate!

Doctor Natalia Chamorro from the Superconducting Materials and Large Scale Nanostructures (SUMAN) group at ICMAB and the Chemistry Department at UAB, defend her PhD thesis entitled “Hybrid approach to obtain high-quality BaMO perovskite nanocrystals for YBaCuO7−δ superconducting nanocomposite” on Thursday, 14 January 2021 in an online session. Congrats!

Abstract: In this work, we present a general hybrid solvothermal methodology to synthesise perovskite BaMO3 nanocrystals with tunable sizes and long-time stability. In contrast with commonly reported methodologies, the combination of aqueous sol-gel and solvothermal treatments not only allowed the successfully production of these particles but also a high tunable control of their size and homogeneity. By using this approximation, we evidence the role of water in the hydrolytic step as the key parameter to tune the size of the final nanocrystals.

In addition we also demonstration the nanocrystals effectiveness to enhance the superconducting properties once the nanocrystals are mixed into YBa2Cu3O7 matrix. Given the novelty and potential relevance of our hybrid method in a deep range of nanoscaled systems.

The PhD thesis was supervised by Ramón Yáñez (UAB) and Susagna Ricart (SUMAN group, ICMAB). The PhD Committee that evaluated the Thesis was formed by Eduardo Solano from the ALBA Synchrotron (President), Roser Pleixats, from the UAB (Secretary) and Amalia Mesaros, from the Universitatea Tehnica Cluj-Napoca, Romania (Vocal). 

Natalia’s PhD thesis was part of the PhD Programme in Materials Science from the Universitat Autònoma de Barcelona (UAB).
