Alkaline Metal Reagent-Assisted Synthesis of Monodisperse Iron Oxide Nanostructures
Metals, 2018 The solvothermal decomposition of iron complexes using the heat-up process enables monodisperse Fe3O4 nanoparticle synthesis. Here, we demonstrate that the high reduction potential capability of alkaline metal reagents in the reductive environment allows

Magnetochemistry, 2022 Single-crystalline magnetite (Fe3O4) particles having a size beyond the nanometric range (1 µm to 50 µm) and showing high (close to the bulk value) saturation-specific magnetization (σs = 92 emu/g), were obtained by the hydrothermal decomposition of the ...

Natural clustering: the modularity approach [PDF]
, 2007 We show that modularity, a quantity introduced in the study of networked systems, can be generalized and used in the clustering problem as an indicator for the quality of the solution. The introduction of this measure arises very naturally in the case of

Magneto‐Ionic Switching of Superparamagnetism [PDF]
Small, 2019 AbstractElectrochemical reactions represent a promising approach to control magnetization via electric fields. Favorable reaction kinetics have made nanoporous materials particularly interesting for magnetic tuning experiments. A fully reversible ON and OFF switching of magnetism in nanoporous Pd(Co) at room temperature is demonstrated, triggered by ...

Magnetic needles and superparamagnetic cells [PDF]
Physics in Medicine and Biology, 2007 Superparamagnetic nanoparticles can be attached in great numbers to pathogenic cells using specific antibodies so that the magnetically-labeled cells themselves become superparamagnets. The cells can then be manipulated and drawn out of biological fluids, as in a biopsy, very selectively using a magnetic needle. We examine the origins and uncertainties

Core-Shell-Nanoparticles with Superparamagnetic Properties for Novel Applications as Biomaterials
Current Directions in Biomedical Engineering, 2023 Due to the increasing average age of the population, the number of implants is also increasing and with it the number of explantations. Therefore, facilitated implant removal is of great interest.

Implications of a temperature-dependent magnetic anisotropy for superparamagnetic switching [PDF]
, 2017 The macroscopic magnetic moment of a superparamagnetic system has to overcome an energy barrier in order to switch its direction. This barrier is formed by magnetic anisotropies in the material and may be surmounted typically after 10^9 to 10^12 attempts
