Finite-size and surface effects in maghemite nanoparticles: Monte Carlo simulations
Finite-size and surface effects in fine particle systems are investigated by Monte Carlo simulation of a model of a g-Fe2O3 ~maghemite! single particle. Periodic boundary conditions for a large enough system have been used to simulate the bulk properties and the results compared with those for a spherical shaped particle with free boundaries to evidence the role played by the surface on the ano...
متن کاملMonte Carlo study of the finite-size effects on the magnetization of maghemite small particles
Monte Carlo simulations of a model for g-Fe2O3 ~maghemite! single particle of spherical shape are presented aiming at the elucidation of the specific role played by the finite size and the surface on the anomalous magnetic behavior observed in small particle systems at low temperature. The influence of the finite-size effects on the equilibrium properties of extensive magnitudes, field coolings...
متن کاملSize and surface effects in the magnetic properties of maghemite and magnetite coated nanoparticles.
An increasing number of promising applications for future technology is arising from size constraints in nanoparticles (NPs) and from the chemical manipulation of their surfaces. In this work, we analyse the finite-size and surface effects on polyacrylic acid-coated Fe(3)O(4) NPs and oleic acid-coated gamma-Fe(2)O(3) NPs by studying their magnetization curves at different temperatures. The meas...
متن کاملSize Effects of Gold and Iron Nanoparticles on Radiation Dose Enhancement in Brachytherapy and Teletherapy: A Monte Carlo Study
Introduction In this study, we aimed to calculate dose enhancement factor (DEF) for gold (Au) and iron (Fe) nanoparticles (NPs) in brachytherapy and teletherapy, using Monte Carlo (MC) method. Materials and Methods In this study, a new algorithm was introduced to calculate dose enhancement by AuNPs and FeNPs for Iridium-192 (Ir-192) brachytherapy and Cobalt-60 (Co-60) teletherapy sources, using...
متن کاملMonte Carlo simulations of surface reactions
Numerical simulations based on the Monte Carlo method offer a powerful approach for detailed studies of complex reaction sequences, such as those associated with heterogeneous catalysis. In this article, we summarize some of the recent work based on discrete models for irreversible surface reactions. Particular emphasis is placed on kinetic phase transitions, bistability, and oscillatory (nonst...
