11 DE FEBRERO, DÍA INTERNACIONAL DE LA MUJER Y LA NIÑA EN LA CIENCIA

El día 11 de Febrero ha sido recientemente proclamado por la Organización de las Naciones Unidas Día Internacional de la Mujer y la Niña en la Ciencia.
Este día ha de servir para mostrar a la sociedad que la ciencia y la tecnología son también cosas de mujeres y qué mejor forma de hacerlo que con nuestras científicas favoritas… ¡las socias del GEFES!

We present our work in the preparation of metallorganic precursor solutions with reduced fluorine content, able to fulfil the requirements for high-performance superconducting YBCO epitaxial layers as a promising approach to low cost and scalable coated conductors. Six different solutions using different quantities of fluorine and non-fluorine carboxylate precursors with a total amount of fluorine from 10 to 50% that of standard trifluoroacetic acid (TFA) solutions. For stabilization purposes different coordinating agents have been used and the solution rheology has been modified for proper substrate wettability. Thermal decomposition analysis and infrared spectroscopy performed directly in films, have revealed that the decomposition takes place in two consecutive stages around 265 and 310 °C respectively, and nuclear magnetic resonance (NMR) analysis could unveil the chemical reactions taking place in the solution. Using the solutions with 20% fluorine and upon optimization of the growth process parameters, YBCO layers with Tc andJc(77 K) of 90 K and 4 MA cm−2 are obtained.

22 January 2016: Neus Roma’s PhD thesis defense

Neus Romà defended his PhD Thesis, entitled “Estudio de soluciones precursoras para el crecimiento de capas superconductoras gruesas por el método de deposición de soluciones químicas”, the jury formed by Maria Lourdes Calzada, Jordi Farjas and Monica Lira awarded her work with an Excel·lent Cum Laude which is the maximum qualification for a PhD thesis at the Universitat Autònoma de Barcelona.

Congratulations Neus!
