We show that very diluted dispersions of ferromagnetic metal nanoparticles in diamagnetic hosts show a large, linear response under an applied magnetic field, which is of interest for emerging applications in sensing, integrated optical communications, and magneto-optical current transformers and transducers.  We present also a theory that describes accurately these results and that can be further extended to describe the optical properties of e.g., metal inclusions in polymers or glasses.

    Dr. Blai Casals Montserrat has defended his PhD thesis, entitled "Magneto-optical spectroscopy and domain imaging of functional oxides" on Friday, September 15th, at 11 am. The ICMAB Sala d'actes Carles Miravitlles was not big enough to fit all the people, including ICMAB colleagues, friends and family, who attented the PhD defense!
  • Iron oxide nanoparticles stress the cells

    07 August 2017 946 hit(s)

    ICMAB researchers lead a study on the toxicity of iron oxide nanoparticles based on the analysis of specific genetic markers linked to nanotoxicity in the C. elegans organisms. Part of the experiment, published in the journal Nanotoxicology, has been carried out at the ALBA Synchrotron, in its infrared light MIRAS beamline. The study suggests that nanoparticles can be captured by intestinal cells in their interior, they can interact with cell lipids, and they can activate cellular mechanisms of oxidative stress.
