I was scientifically trained in magnetoelastic resonance measurements (WP1).
Samples of magnetoelastic resonators were prepared and optimized in order to present a higher resistance to corrosion (WP 2).
The composition Fe54Ni24Si10B10 was prepared by melt spinning in BCMaterials center. Posteriorly, samples with the same composition were prepared in a secondment in the company Vacuumschmelze gmbh & co. kg, with different thickness.Different compositions were also prepared and testes in Vacuumschmelze. (WP2)
An extensive study on the experimental determination of the Q factor in such magnetoelastic resonant platforms, using three different strategies was performed, since this is a determinant parameter in the increase of magnetoelastic ribbons mass sensitivity (WP2).
For the first time, different geometries (non rectangular) of magnetoelastic ribbon were used in the dectection of mass variation. The results showed that this is a crucial factor in the improvement of the performance of the sensors.(WP2)
I was scientifically trained in biological methods. (WP1)
The propagation of bacteriophage M13 was realized such as the obtention of E-coli population. Those were immobilized on magnetoelastic resonator by physical adsorption after their functionalization with specific functional groups. (WP 3 and WP4)
Finally, of different concentrations of E-coli population were detected with magnetoelastic ribbons using the new geometries. (WP 5)
I also collaborate in training students by suppervision of final projects of master students within the master in "New Materias" of the University of Basque Country as well as in the supervision of a PhD student under the Doctoral program of Science and Technology of Materials, also from the University of Basque Country. (WP1)
The dissemination and exploration of the results was done by preparation of papers and participation in conferences: (WP 6)
