Study the stability of Si, Ge, Fe and Co in the interior surface of metallic carbon nanotube for hydrogen storage
In this article, we have performed calculations for studying the stability of the carbon group elements such as Si and Ge and also the magnetic elements like Fe and Co via first principle investigations. We found that Si and Ge decoupled from the interior surface of carbon nanotubes, this fact was independent in curvature, radius, conductivity and numbers of atoms in the carbon nanotubes. But t...
متن کاملImproving the Magnetic Properties Co2FeSi Heusler Compound by Modifying the Crystalline Order in Different Manufacturing Procedures
In this study, the improvement of the magnetic properties of Co2FeSi Heusler compound was followed by the utilization of different experimental synthesizing procedures. Comparing the crystal structure showed that the milled samples had a higher crystalline order than the arc-melted ones. Annealing of the milled sample improved the crystalline order, resulting in the highest saturation magnetiza...
متن کاملDensity Functional Studies on Crystal Structure and electronic properties of Potassium Alanate as a candidate for Hydrogen storage
Potassium Alanate is one of the goal candidates for hydrogen storage during past decades. In this report, initially the Density Functional Theory was applied to simulate the electronic and structural characteristic of the experimentally known KAlH4 complex hydride. The relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
متن کاملAn investigation of the effect of hyperthermia using iron and magnetic nanoparticles in cancer treatment
Introduction: hyperthermia using different methods such as microwave and magnetic waves is one of the methods to treat cancer. In this method, iron and magnetic nanoparticles are used to increase the temperature and increase the effect of hyperthermia as auxiliary treatment with chemotherapy and radiotherapy. In this study, the role of iron and magnetic nanoparticles have been ...
متن کاملThe synergistic character of the defect-induced magnetism in diluted magnetic semiconductors and related magnetic materials.
In this work, we introduce a new perspective in explaining the origin of magnetism in dilute magnetic semiconductors, carbon-based materials and other related materials. According to our proposal, the magnetism in these materials is the result of the synergistic action of defect-induced electronic processes mostly of local character which can provide magnetic moments and develop a ferromagnetic...
