Abstract
In this seminar, Dr Martín Jefremovas will present key findings from her current MSCA-YIA project, HYPUSH, which seeks to harness intra-particle magnetic inhomogeneities to enhance the therapeutic efficiency of magnetic hyperthermia.
The presentation will focus on maghemite nanoflowers, which are excellent nanotransducers in this field. Despite their efficiency, the influence of intra-particle disorder on their heat release has remained elusive. By employing micromagnetic simulations and small-angle neutron scattering, her research has modelled these specific morphologies and their associated spin textures. This approach allows for the identification of intra-particle “hot-spots” of energy dissipation, providing predictive metrics for the design of optimised nanoparticles in biomedical applications.
About the speaker
Elizabeth Martín Jefremovas is a postdoctoral researcher in the Nanomag group at the University of Luxembourg. She earned her PhD in “Spin dynamics in magnetic nanoparticles” from the University of Cantabria in 2021. Her distinguished career includes an Alexander von Humboldt postdoctoral fellowship at Johannes Gutenberg University Mainz (2022–2024), where she worked on the “3D-SKY” project. She is currently a Marie-Curie-Young International Academics fellow, focusing on elucidating the paradigm of spin disorder in magnetic nanomaterials.
