Bilayer films that combine chitosan and alginate, two natural polysaccharides, and magnetic iron oxide nanoparticles (MNPs) were obtained. Physical and microscopic observations revealed that chitosan and alginate interact ...

Magnetic nanoparticles (MNPs) encapsulated in polymeric systems are promising materials for hyperthermia treatments and targeting drug delivery in cancer therapy. To improve the encapsulation efficiency of therapeutic ...

We investigate the influence of sub-Ohmic dissipation on randomly diluted quantum Ising and rotor models. The dissipation causes the quantum dynamics of sufficiently large percolation clusters to freeze completely. As a ...

En este trabajo presentamos un marco completo de para la simulación atomística de materiales magnéticos patronados. Tiene características que permiten la observación de efectos causados por impurezas magnéticas en la matriz ...

Magnetic nanocomposites using chitosan as a matrix and magnetite nanoparticles generated "in situ" were prepared and magnetically characterized. The content of nanoparticles on the composites was varied from 2 to 10 wt.% ...

This work investigates the structure and magnetic properties of chitosan based films with different contents of magnetic nanoparticles (MNPs) of around 10 nm as well as the effects of the addition of glycerol as plasticizer. ...

In this work, sodium alginate was used as the polymeric matrix of magnetic nanocomposite films where iron oxide particles, in percentages varying from 2 to 10 wt.% (respect to alginate content), were synthesized “in situ”. ...

We study a model of localized spins which can assume three different states, S = 0 and 1, with two competing interactions: a antiferromagnetic first neighbour interaction (JA) and a three body interaction between third ...

Superparamagnetic iron oxide nanoparticles (MNP) were synthesized and incorporated into alginate film forming solutions, leading to composite magnetic films. Both plasticized and non-plasticized films were obtained after ...
