NANOMATERIALS PHYSICAL PROPERTIES SIMULATION AND MODELING APPLICATIONS
Journal Title: Journal of Science And Arts - Year 2009, Vol 10, Issue 1
Abstract
Modeling of nanomaterials requires realistic description of the system across various length and time scales. In order to illustrate how atomistic modeling is being used to determine the structure, physical, and chemical properties of materials at the nanoscale, molecular dynamics (MD) simulations will be presented for nanoscale assemblies based on carbon nanotubes, diamond surfaces, metal alloy nanowires, and ceramics. Some possible applications of atomistic modeling to carbon nanotubes, diamond surfaces, metallic nanowires, and organic liquids confined to nanoscale slits and structural transitions in ceramics will be also presented. These simulations use recent developments in force fields for metals, alloys, ceramics, and various phases of carbon which are also summarized here. This gives some glimpse of the enormous role that theory and modeling is likely to play as nanoscale science becomes a central theme in the 21st century technology.

BINARY OPERATIONS ASSOCIABLE WITH A GROUP OPERATION
Conditions under which two binary operations on a set M are associable (x○(y*z)=(x○y)*z, z,y,zєM) were given by J. Dhombres in the case when the operations are associative. We characterize the associability of two group...
ULTRASONIC PROPERTIES OF ANCIENT CERAMIC MATERIALS WITH POROUS STRUCTURE
This paper reports a new method of estimating mechanical properties of ancient ceramic materials from the ultrasonic properties. The methodology is based on the observation that the ratio of normalized value of Young's m...
SOLUTION OF TIME INDEPENDENT SCHRÖDINGER EQUATION FOR THE QUANTUM HARMONIC OSCILLATOR USING FRACTIONAL HARTLEY TRANSFORM
In this paper we have proved some operation transform formulae for fractional Hartley transform in section 2. Solution of Time Independent Schrödinger Equation for the Quantum Harmonic Oscillator was found using the abov...

In this paper we give some integral forms of some refinements and counterparts of Radon’s inequality using recent generalizations.
SOME MODELS OF DISSIPATIVE PROCESSES IN PHASE TRANSFORMATIONS ON A WIDE RANGE OF TEMPERATURES
The phase transitions in solid materials (called solid-solid transformations) are connected with the thermo dynamical processes with hysteresis, leading to the dissipative models. Obvious, the liquid-solid transitions ar...
