The project is entitled “Ultrafast growth of ultrahigh performance superconducting tapes (ULTRASUPERTAPE)” and has been granted under the Panel PE8 “Products and Processing Engineering”. An unprecedented approach for low cost / high throughput / high performance High Temperature Superconducting tapes for the new clean, efficient and smart energy paradigm is envisaged. A transient liquid assisted growth (TLAG) in chemical solution deposited layers is used to reach ultrafast growth of thick superconducting tapes. An integrated system based on additive manufacturing and digital printing is devised to address a competitive manufacturing process with very high throughput and low cost, where combinatorial chemistry is selectively used for fast screening. Ultra-high tapes performances at high and ultrahigh magnetic fields are envisioned by maximizing the superconducting condensation energy with local strain and electronic state engineering.

Alexander Stangl

alexander stangl Hola! My name is Alex and I just started my PhD in Physics in superconductivity. I love the idea to work in a field which might change our future to a greener one (loss less power grids, fusion plants, energy storages for green energy) and combines basic research with applications. I graduated from Vienna University of Technology but studied some semesters abroad in Göttingen, Germany and at the High Magnetic Field Lab in Tallahassee, Florida. I enjoy deepening my knowledge and understanding of physics and traveling and experiencing new cultures at the same time and  I’m looking forward to a fruitful and great time with all of you here at the ICMAB!

Ultrafast Crystallization of Ce0.9Zr0.1O2–y Epitaxial Films on Flexible Technical Substrates by Pulsed Laser Irradiation of Chemical Solution Derived Precursor Layers

cg-2015-001156_0010 A. Queraltó, A. Pérez del Pino, M. de la Mata, J. Arbiol, X. Obradors and T. Puig Crystal Growth and Design 15, 1957-1967 (2015) DOI: 10.1021/acs.cgd.5b00115 The epitaxial growth of Ce0.9Zr0.1O2–y (CZO) thin-films on yttria-stabilized zirconia (YSZ) (001) single crystal and YSZ (001)/stainless steel (YSZ/SS) technological substrates is investigated by pulsed laser irradiation of solution-derived cerium–zirconium precursor layers using a UV Nd:YAG laser source at atmospheric conditions. The influence of laser processing parameters on the morphological and structural properties of the obtained films is studied by atomic force and transmission electron microscopies, as well as X-ray diffractometry. The analyses performed demonstrate that laser treatments enable the epitaxial growth of tens of nanometers thick CZO films with a crystallization kinetic process several orders of magnitude faster than that of conventional thermal annealing. Fully epitaxial films are attained using stainless steel (SS) flexible tapes as a substrate. Even though photochemical mechanisms are not fully discarded, it is concluded that photothermal processes are the main contribution responsible for the fast epitaxial crystallization.

Thermal analysis of metal organic precursors for functional oxide preparation: Thin films versus powders

1-s2.0-S0040603114005693-fx1 P Roura, J. Farjas, H. Eloussifi, L. Carreras, S. Ricart, T. Puig Molina and X. Obradors Thermochimica Acta 601, 1-8 (2015) DOI:10.1016/j.tca.2014.12.016 The thermal decomposition of several metal organic precursors, used in the preparation of YBa2Cu3O7−xsuperconducting coated conductors (Cu acetate, Cu, Y and Ba trifluoroacetates and Ce propionate) is analyzed by means of several thermoanalytical techniques (TG/DTA, MS and DSC). In all cases, the metal organic precursors deposited as thin films decompose differently than powders from the same precursors. In thin films, decomposition is facilitated by the easier transport of reactive gas from the surrounding atmosphere and by the easier out-diffusion of volatile products. Consequently, films decompose at lower temperature and are more sensitive to the presence of any residual reactive gas in the furnace. Good thermal contact with the substrate is also shown to minimize overheating in films and avoid combustion processes that are otherwise often observed during the thermal decomposition of powders. Finally, the formation and stability of intermediate products towards the oxide formation, such as metal fluorides, differs in films because of the easier gas exchange. With respect to powders, these compounds are much less stable in films, where their decomposition temperature can be lowered by several hundreds of degrees Celsius. While in some cases the behaviour of films can be predicted by analyzing varying masses of precursor powders, this is not always the case. Therefore, thermal analysis carried out on films is recommended to avoid erroneous conclusions about materials preparation drawn from powders.

[su_slider source=”media: 839,838,835″ target=”blank” height=”400″ title=”no”] From 20th to 28th of October, Dr. Anna Palau and PhD student Ferran Vallès visited the high magnetic field laboratory LNCMI in Grenoble to perform electric transport measurements at up to 29T on CSD-YBCO thin films with the collaboration of the local contact Dr. Xavier Chaud.


image008 Our project manager, Dr. Mar Tristany, has participated in the PAN EUROPEAN NMP CLUSTER VISION2020 organized by LEITAT the 31st October in Terrassa. The event focused on addressing the Horizon 2020 NMP2014 calls for proposals, and included talks by several invited speakers from Vision 2020, the EU and industry. During the Open Brokerage Session, we presented some proposal ideas for the NMP Calls 2015.
