NANO TECHNOLOGY: MOLECULAR SIMULATION

Nano-technology and nano-toxicology

Rapid developments in nano-technology are likely to confer significant benefits on mankind. But, as with perhaps all new technologies, these benefits are likely to be accompanied by risks, perhaps by new risks. Nano-toxicology is developing in parallel with nano-technology and seeks to define the hazards and risks associated with nano-materials: only when risks have been identified they can be ...

Nano Technology

We present a new approach using genetic algorithms, neural networks, and nano robotics concepts applied to the problem of control design for nanoassembly automation and its application in medicine. As a practical approach to validate the proposed design, we have elaborated and simulated a virtual Environment focused on control automation for nano robotics teams that exhibit collective behavior....

Nano-technology: a Disruptive Technology?

Simulation of Nano-scale Cutting with Molecular Dynamics

The simulation of nanometric cutting of copper with diamond cutting tools, with the Molecular Dynamics method is considered. A 2D model of orthogonal nano-scale cutting is presented and the influence of the depth of cut and tool rake angle on chip morphology and cutting forces is investigated. For the analysis, three different depths of cut, namely 10Å, 15Å and 20 Å and four tool rake angles, n...

Molecular Dynamics Simulation and Its Application to Nano-rheology

Over the last 15 years molecular dynamics (MD) simulations have become one of the important tools to tackle many of the complex problems that are faced by rheologists and engineers. The advent of modern areas of science such as nanotechnology and the need to understand physical phenomena including rheology and tribology at the molecular scale have helped the growth of research both experimental...
