Single-particle Langevin model of particle temperature in dusty plasmas
A model of heating a particle in a dusty plasma is developed to predict the particle kinetic temperature. A Langevin approach is developed, generalizing a familiar Brownian motion model. Particles are cooled by neutral gas while being heated by one of two mechanisms: fluctuating electric fields and randomly fluctuating particle charge. Expressions are derived for the particle temperature result...
متن کاملPhase Diagram of Strongly Coupled Yukawa Particulates in Deformable Background and Application to Fine Particle (Dusty) Plasmas
We analyze thermodynamics of the system composed of charged particles with hard cores interacting via the repulsive Yukawa potential and the ambient plasma (of ions and electrons), taking the contribution of the latter properly into account. When the Coulomb coupling between particles becomes sufficiently strong, the isothermal compressibility of the whole system diverges and we have a phase se...
متن کاملDynamics in fine particle magnets
Several magnetic fine particle systems have been studied with selective excitation double Mössbauer ~SEDM! spectroscopy. Static disorder, collective excitations, and superparamagnetic spin flips are all detected and their contributions quantified. Zero-field muon spin relaxation spectroscopy has been used to confirm these observations in one sample. A theoretical description of SEDM spectra in ...
متن کاملResponsive Binders for Controlling Dispersion Behavior of Fine- Particle Clusters
Agglomerates of fine particles are frequently encountered in a wide range of important chemical, biotechnical, medical and materials processing applications including pharmaceutical, polymer, mining, and food technologies. Often, the processing goal is the dispersion of the agglomerate into smaller clusters (or if possible, into its constituent particles) and distribution of these finely divide...
متن کاملInteraction Fields Evaluation in Fine Particle Systems
A computer simulation model for estimation of the interaction fields in fine particle systems has been developed. The method uses the experimental Ma(H) plot, constructed from the Fourier description of the initial magnetization curve and the hysteresis loop, and the M(H) plot, obtained from the remanence curves. The dependencies of the interaction fields on the external magnetic field have bee...
