In this work, we studied the effect of zinc and manganese doping on the magnetic and structural properties of MNPs synthesized by the microwave-assisted polyol process, using diethylene glycol (DEG) and tetraethylene glycol (TEG) as polyols. The detailed morpho-structural and magnetic characterization showed a correspondence between the higher amounts of Mn and smaller crystal sizes of the MNPs. Such size reduction was compensated by an increase in the global magnetic moment so that it resulted in an increase of the saturation magnetization. Saturation magnetization MS values up to 91.5 emu/g and NMR transverse relaxivities r2 of 294 s−1mM−1 were obtained for Zn and Mn- doped ferrites having diameters around 10 nm, whereas Zn ferrites with diameters around 15 nm reached values of MS∼ 97.2 emu/g and of r2∼ 467 s−1mM−1, respectively. Both kinds of nanoparticles were synthesized by a simple, reproducible, and more sustainable method that makes them very interesting for diagnostic applications as MRI contrast agents. info:eu-repo/grantAgreement/EC/H2020/101007629 /EU/Nanomaterials for Enzymatic Control of Oxidative Stress Toxicity and Free Radical Generation/NESTOR This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101007629 -NESTOR info:eu-repo/grantAgreement/EC/H2020/829162/EU/Redesigning biocatalysis: Thermal-tuning of one-pot multienzymatic cascades by nanoactuation/HOTZYMES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 829162-HOTZYMES info:eu-repo/grantAgreement/EC/H2020/853468/EU/Remote control of cellular signalling triggered by magnetic switching/SIROCCO This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 853468-SIROCCO info:eu-repo/grantAgreement/ES/MICINN/PID2020-113480RB-I00 info:eu-repo/grantAgreement/ES/MINECO/SEV-2016-0686 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.3 2022 PHYSICS, APPLIED 39 / 160 = 0.244 2022 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 51 / 107 = 0.477 2022 Q2 T2 CHEMISTRY, MULTIDISCIPLINARY 58 / 178 = 0.326 2022 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 110 / 343 = 0.321 2022 Q2 T1 0.811 2022 Chemical Engineering (miscellaneous) 2022 Q1 Materials Science (miscellaneous) 2022 Q2 7.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Morales, María del Puerto Gallo-Cordova, Alvaro Espinosa, Ana Moros, María (orcid)0000-0002-2861-2469 Brero, Francesca Mariani, Manuel Lascialfari, Alessandro Ovejero, Jesús G. 12, 19 (2022), 3304 [12 pp.] Nanomaterials (Basel) Nanomaterials 2079-4991 6254399 http://zaguan.unizar.es/record/120132/files/texto_completo.pdf Versión publicada 2703491 http://zaguan.unizar.es/record/120132/files/texto_completo.jpg?subformat=icon icon Versión publicada oai:zaguan.unizar.es:120132 articulos driver 2024-03-18-16:41:22 ARTICLE
