Characterization of the order-disorder transition of a charged hard-sphere model.

چکیده
Monte Carlo simulations at constant pressure are used to characterize the structure of the restricted primitive model in the tetragonal-ordered solid phase. A method to estimate the location of the order-disorder transition and the densities of the coexistence phases is discussed. The results support the weakly first-order character of the transition.

Order-disorder transition in the solid phase of a charged hard sphere model.
We investigate the solid phases of the restricted primitive model (RPM). Monte Carlo simulations show the existence of an order-disorder transition from a substitutionally disordered face centered cubic lattice (fcc) to a new ordered fcc structure which is proposed as the ground state of the RPM at the close packing density. Our results suggest that the new phase might turn out in a new triple ...
متن کاملSolvation Force in Hard Ellipsoid Molecular Liquids with Rod-Sphere and Rod- Surface Interactions
In previous work, one of us calculated the Solvation force of hard ellipsoid fluid with hard Gaussian overlap potential using hard needle wall interaction and non-linear equation proposed by Grimson- Rickyazen. In present work, using density functional theory and extended restricted orientation model, the solvation force of hard ellipsoid fluid in presence of more realistic rod- sphere and rod-...
متن کاملSynthesis and characterization of Alumina (Al2O3) nanoparticles prepared by simple sol-gel method
Alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. This study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. Aluminium oxide (Al2O3) nanoparticles were synthesized by iron (III) nitrate 9-hydrate as precursor. Physicochemical properti...

متن کاملشبیه سازی اثر بی نظمی و میدان مغناطیسی بر ترابرد کوانتومی نانوساختارهای دو بعدی مدل شده با تقریب تنگابست
In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
