RF Dynamics in Nanoparticle Systems With Tuned Strength of Interactions
نویسنده
چکیده
The dynamic response in a large experimental time window (10 –10 s) of Co and CoPt nanoparticle systems is reported. In order to reveal the dynamics effects, along with classic experiments as a.c. susceptibility and static magnetic measurements, a rf temperature dependent transverse susceptibility experiment is used. To study the effect of interaction between particles, samples of Co and CoPt nanoparticles dispersed in an insulated matrix in different volume fractions were investigated.

Effect of shear on nanoparticle dispersion in polymer melts: A coarse-grained molecular dynamics study.
Coarse-grained, molecular dynamics (MD) simulations have been conducted to study the effect of shear flow on polymer nanocomposite systems. In particular, the interactions between different components have been tuned such that the nanoparticle-nanoparticle attraction is stronger than nanoparticle-polymer interaction, and therefore, the final equilibrium state for such systems is one with cluste...
متن کاملGlobal Stabilization of Attitude Dynamics: SDRE-based Control Laws
The State-Dependant Riccati Equation method has been frequently used to design suboptimal controllers applied to nonlinear dynamic systems. Different methods for local stability analysis of SDRE controlled systems of order greater than two such as the attitude dynamics of a general rigid body have been extended in literature; however, it is still difficult to show global stability properties of...
متن کاملEffect of the Interparticle Interactions on Adsorption-Induced Frequency Shift of Nano-beam-Based Nanoscale Mass-Sensors: A Theoretical Study
It is well-known that the Interparticle interactions between adsorbates and surface of an adsorbent can affect the surface morphology. One of the consequences of this issue is that the resonant frequency of a nanoscale resonator can be changed due to adsorption. In this study we have chosen a cantilever-based nanoscale mass-sensor with a single nanoparticle at its tip. Using the classical...
متن کاملA molecular dynamics simulation study of nanoparticle interactions in a model polymer-nanoparticle composite
Molecular dynamics (MD) simulations were performed on a model polymer–nanoparticle composite (PNPC) consisting of spherical nanoparticles in a bead-spring polymer melt. The polymer-mediated effective interaction (potential of mean force) between nanoparticles was determined as a function of polymer molecular weight and strength of the polymer–nanoparticle interaction. For all polymer–nanopartic...
متن کاملMolecular dynamics simulation of a polymer melt with a nanoscopic particle
We perform molecular dynamics simulations of a bead-spring polymer melt surrounding a nanoscopic particle. We explore the effect of the polymer/nanoparticle interactions, surface-to-volume ratio, and boundary conditions on both the structure and dynamics of the polymer melt. We find that the chains near the nanoparticle surface are elongated and flattened and that this effect is independent of ...
