crystallization of aluminum fluoride at atmospheric pressure has been considered. structure, size and shape of crystals formed during the crystallization process have been investigated. by applying the direct analysis method for the existed aluminum in solution, the aluminum fluoride nucleation process has been detected as a concentration valley at the outset of crystallization process. the lin...

metal nanoshells consists of a dielectric core surrounded by a thin noble metal shell, possess unique optical properties, which render nanoshells attractive for use in different technologies. this paper reports a facile method for growth of small gold nanoparticles on the functionalized surface of larger silica nanoparticles. mono-dispersed silica particles and gold nanoparticles were prepared ...

We study electronic and topographic properties of the Si(335) surface, containing Au wires parallel to the steps. We use scanning tunneling microscopy (STM) supplemented by reflection of high energy electron diffraction (RHEED) technique. The STM data show the space and voltage dependent oscillations of the distance between STM tip and the surface which can be explained within one band tight bi...

We observed that radio-frequency (rf) irradiation significantly enhances the c-axis resistance near and below the superconducting transition of the CuO2 layer in contact with a normal-metal electrode on the surface of Bi2Sr2CaCu2O8+x single crystals. We attribute the resistance anomaly to the rf-induced charge-imbalance nonequilibrium effect in the surface CuO2 layer. The relaxation of the char...

Diffuse coplanar surface barrier discharge (DCSBD) as the source of nonequilibrium plasma is widely used nowadays for surface modification of different materials. DCSBD plasma consists of many microdischarges which are moving along the planar dielectric plate and create a thin layer of macroscopically homogeneous plasma above dielectric. The influences of humidity in carrier gas at atmospheric ...

A 3-parameter local hot spot model of gas-surface reactivity is employed to analyze and predict dissociative sticking coefficients for CH(4) incident on Ir(111) under varied nonequilibrium and equilibrium conditions. One Ir surface oscillator and the molecular vibrations, rotations, and translational energy directed along the surface normal are treated as active degrees of freedom in the 14 dim...

We present nonequilibrium molecular dynamics simulations of planar elongational flow (PEF) by an algorithm proposed by Tuckerman et al. [J. Chem. Phys. 106, 5615 (1997)] and theoretically elaborated by Edwards and Dressler [J. Non-Newtonian, Fluid Mech. 96, 163 (2001)], which we shall call the proper-SLLOD algorithm, or p-SLLOD for short. [For background on names of algorithms see W. G. Hoover,...

We report numerical investigations of a 3D model of diffusive growth of fine particles, the internal structure of which corresponds to different crystal lattices. A growing cluster (particle) is immersed in and exchanges monomer building blocks with a surrounding medium of diffusing (off-lattice) monomers. On-surface dynamics of the latter is accounted for by allowing, in addition to detachment...

A three-parameter local hot spot model of gas-surface reactivity is employed to analyze and predict dissociative sticking coefficients for SiH4 incident on Si(100) under varied nonequilibrium conditions. Two Si surface oscillators and the molecular vibrations, rotations, and translational energy directed along the local surface normal are active degrees of freedom in the 15 dimensional microcan...
