Using a simple method we produce polyethylene film with embedded chains of cobalt nanoparticles. The crystalline magnetic nanoparticles were synthesized through a simple chemical reduction method at room temperature using ultrasonic assistance. These

The hysteresis curves of systems composed of small interacting magnetic particles, regularly placed on a two-dimensional lattice, are obtained with Monte Carlo simulations, for magnetic fields on the plane of the monolayer. The remanence as a functio

The magnetization reversal of three-segment cylindrical nanoelements comprising of alternating nanowire and nanotube sections is investigated by means of Monte Carlo simulations. Such nanoelements may feature a three-state behaviour with an intermedi

The formation of the lamellar pattern in thin films of even diblock copolymers confined by hard walls is studied. The analysis of the free energy of a film with lamellae parallel to the confining walls, in the weak segregation regime, indicates that,

The microphase separation of symmetric diblock copolymers in the presence of an external force field is simulated by means of a cell dynamical system model. It is found that the pattern formation is greatly affected by the presence of the field and b

The possibility of a three-state nanoelement, composed by a wire and a tube, is investigated by means of Monte Carlo simulations. The desired behavior may be identified by a step or plateau in the hysteresis curve, corresponding to a partial pinning

We propose a computationally efficient discrete model with short-range coupling for a system of limit cycle oscillators. Depending on the intensity of the coupling and of the attraction to the limit cycle, the system exhibits synchronization, amplitu

The internal morphology and magnetic properties of layer-by-layer assembled nanofilms of polyaniline (PANI) and maghemite (γ-Fe2O3—7.5-nm diameter) were probed with cross-sectional transmission electron microscopy (TEM) and magnetization measureme

The possibility of confining magnetic nanoparticles inside multisegmented nanotubes by using strong field gradients is considered by means of Monte Carlo simulations. The problem is reduced to the random walk performed by the nanoparticle on the ener

During the last years great attention has been given to the encapsulation of magnetic nanoparticles. In this work we investigated the stability of small magnetic particles inside magnetic nanotubes. Multisegmented nanotubes were tested in order to op
