Superparamagnetic colloids in viscous fluids [PDF]
Scientific Reports, 2017 AbstractThe influence of a magnetic field on the aggregation process of superparamagnetic colloids has been well known on short time for a few decades. However, the influence of important parameters, such as viscosity of the liquid, has received only little attention.

Shaping the Assembly of Superparamagnetic Nanoparticles [PDF]
ACS Nano, 2019 Superparamagnetism exists only in nanocrystals, and to endow micro/macro-materials with superparamagnetism, superparamagnetic nanoparticles have to be assembled into complex materials. Most techniques currently used to produce such assemblies are inefficient in terms of time and material.

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

Nanochains Formation of Superparamagnetic Nanoparticles [PDF]
The Journal of Physical Chemistry C, 2011 We present simulations on the aggregation of nanometer sized polydispersed superparamagnetic particles under the application of an external magnetic field. We make use of a Monte Carlo method, using a cluster-moving approach, as previously used in literature for ferrofluids. van der Waals attraction and magnetic anisotropy are taken into account in the

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 ...
