Hybrid magnetic nanoparticles as efficient nanoheaters in biomedical applications
(Royal Society of Chemistry, 2021-02)
Heating at the nanoscale is the basis of several biomedical applications, including magnetic hyperthermia therapies and heat-triggered drug delivery. The combination of multiple inorganic materials in hybrid magnetic ...
Dynamic symmetry loss of high-frequency hysteresis loops in single-domain particles with uniaxial anisotropy
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Understanding how magnetic materials respond to rapidly varying magnetic fields, as in dynamic hysteresis loops, constitutes a complex and physically interesting problem. But in order to accomplish a thorough investigation, ...
Magnetic coupled electrochemistry: Exploring the use of superparamagnetic nanoparticles for capturing, transporting and concentrating trace amounts of analytes
(ELSEVIER SCIENCE INC, 2011)
We propose the use of functionalized superparamagnetic nanoparticles for capturing, and transporting analytes, in association with an external miniature magnet to deposit such nanocarrier species at the electrode surface. ...
Synthesis of highly stable Fe/FeOx@citrate colloids with strong magnetic response by mechanochemistry and coprecipitation for biomedical and environmental applications
(Elsevier Science, 2020-03)
We present a simple, scalable, and low-cost route for producing aqueous colloids of nanometer size Fe cores coated with iron oxide and stabilized with sodium citrate. The Fe cores were obtained by mechanosynthesis by means ...
Homologous flares and magnetic field topology in active region NOAA 10501 on 20 November 2003
(Springer, 2011-03)
We present and interpret observations of two morphologically homologous flares
that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homologous Hα ribbons and were both accompanied ...
Relaxation time diagram for identifying heat generation mechanisms in magnetic fluid hyperthermia
(Springer, 2014-12)
We present a versatile diagram to envisage the dominant relaxation mechanism of single-domain magnetic nanoparticles (MNPs) under alternating magnetic fields, as those used in magnetic fluid hyperthermia (MFH). The diagram ...
Oxidation processes and their effects on the magnetic remanence of Early Cretaceous subaerial basalts from Sierra Chica de Córdoba, Argentina
(Geological Soc Publ House, 2014-09)
We carried out magnetic analyses on a sequence of Cretaceous alkaline–transitional subaerial basalts of Co´rdoba Province, Argentina, which have high-Ti magnetite as the main opaque phase. Three different groups are ...
Multifunctional antitumor magnetite/chitosan-l-glutamic acid (core/shell) nanocomposites
(Springer, 2011-09-01)
The development of anticancer drug delivery systems based on biodegradable nanoparticles has been intended to maximize the localization of chemotherapy agents within tumor interstitium, along with negligible drug distribution ...
