I found the field of Science & Technology – Other Topics; Materials Science; Physics very interesting. Saw the article Adjusting the Neel relaxation time of Fe3O4/ZnxCo1-xFe2O4 core/shell nanoparticles for optimal heat generation in magnetic hyperthermia published in 2021. SDS of cas: 103-50-4, Reprint Addresses De Biasi, E; Winkler, EL (corresponding author), Consejo Nacl Invest Cient & Tecn, Ctr Atom Bariloche, Inst Nanociencia & Nanotecnol CNEA, RA-8400 San Carlos De Bariloche, Argentina.; De Biasi, E; Winkler, EL (corresponding author), Univ Nacl Cuyo, Inst Balseiro, Mendoza, Argentina.. The CAS is 103-50-4. Through research, I have a further understanding and discovery of Benzyl ether
In this work it is shown a precise way to optimize the heat generation in high viscosity magnetic colloids, by adjusting the Neel relaxation time in core/shell bimagnetic nanoparticles, for magnetic fluid hyperthermia (MFH) applications. To pursue this goal, Fe3O4/ZnxCo1-xFe2O4 core/shell nanoparticles were synthesized with 8.5 nm mean core diameter, encapsulated in a shell of similar to 1.1 nm of thickness, where the Zn atomic ratio (Zn/(Zn + Co) at%) changes from 33 to 68 at%. The magnetic measurements are consistent with a rigid interface coupling between the core and shell phases, where the effective magnetic anisotropy systematically decreases when the Zn concentration increases, without a significant change of the saturation magnetization. Experiments of MFH of 0.1 wt% of these particles dispersed in water, in Dulbecco modified Eagles minimal essential medium, and a high viscosity butter oil, result in a large specific loss power (SLP), up to 150 W g(-1), when the experiments are performed at 571 kHz and 200 Oe. The SLP was optimized adjusting the shell composition, showing a maximum for intermediate Zn concentration. This study shows a way to maximize the heat generation in viscous media like cytosol, for those biomedical applications that require smaller particle sizes.
