Monnier, Christophe A. Crippa, Federica Geers, Christoph Knapp, Evelyne Rothen-Rutishauser, Barbara Bonmarin, Mathias Lattuada, Marco Petri-Fink, Alke 2017-12-07 Magnetic nanoparticles and their ability to convert electromagnetic energy into heat are of explicit interest for various applications. However, precise quantification of their heating efficiency is not always upfront, and several parameters render comparative studies challenging. This paper describes the theory behind lock-in thermography, a new technique for quantifying the heating properties of magnetic nanoparticles. This technique allows the investigation of some of the potential sources of variability: key factors such as magnetic field inhomogeneity and its effects on the heating power are explored in detail. The presented results, obtained from various nanoparticle batches of different origins, highlight the importance of pursuing a standardized and systematic approach when quantifying the heating efficiency of magnetic nanoparticles. application/pdf https://folia.unifr.ch/global/documents/306341 https://folia.unifr.ch/documents/306341/files/lat_lta.pdf https://folia.unifr.ch/documents/306341/files/lat_lta_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1021/acs.jpcc.7b09094 info:eu-repo/semantics/openAccess License undefined The Journal of Physical Chemistry C. - 2017, vol. 121, no. 48, p. 27164–27175 info:eu-repo/classification/udc/54 Lock-in thermography as an analytical tool for magnetic nanoparticles: measuring heating power and magnetic fields http://purl.org/coar/resource_type/c_6501
