For many decades, nanotechnology has been developed with cooperation from researchers in several fields of studies including physics, chemistry, biology, material science, engineering, and computer science. In this chapter, we explore the nanotechnology development community and identify the needs and opportunities of computer science research in nanotechnology. In particular we look at methods...

The field equations and boundary conditions of Hořava-Witten theory, compactified on a smooth compact quotient of CH, where CH denotes the hyperbolic cousin of CP, are studied in the presence of Casimir energy density terms. If the Casimir energy densities near one boundary result in a certain constant of integration taking a value greater than around 10 in units of the d = 11 gravitational len...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...

We develop a network model of bone microstructure and dynamics, BoneNET, which is capable of quantitative assessment of Bone Mineral Density (BMD) and bone remodelling dynamics. First, we introduce a network model of bone microstructure by describing structural properties and process of bone network modelling. Secondly, we explain a mathematical model of bone microstructure by analysing the den...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...

In this study, the changes in microstructure of HP-Nb cast heat resistant steel after 8 years of service at high temperatures were investigated. Study of microstructure using optical microscopy (OM) and scanning electron microscopy (SEM) equipped with an energy dispersive spectrometry (EDS) showed that the microstructure of this steel in as-cast condition includes an austenitic matrix, and that...
