چکیده

We use quantum mechanics to characterize the structure and current-voltage (I-V) performance of the Stoddart-Heath rotaxane-based programmable electronic switch. We find that the current when the ring is on the DNP is 37~58 times the current when the ring is on the TTF, in agreement with experiment (ratio of 10 to 100). The basis is now established for iterative experimental-theoretical efforts to optimize systems for molecule based electronics which we illustrate by predicting the effect of adding a group such as CN group to the rotaxane.

Planar Molecular Dynamics Simulation of Au Clusters in Pushing Process

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...

Combining agoric and genetic methods in stochastic design

Molecular nanotechnology will be physically capable of producing objects whose complexity exceeds that of any currently designed artifact by several orders of magnitude. Designs which make more than non-trivial use of this capability are beyond the capabilities of human designers, even using current CAD methods. Thus automatic design, or at least an improvement in automation over existing pract...

Computer Aided Molecular Modeling Of Membrane Metalloprotease

Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

Computational Aided-Molecular Imprinted Polymer Design for Solid Phase Extraction of Metaproterenol from Plasma and Determination by Voltammetry Using Modified Carbon Nanotube Electrode

A molecular imprinted polymer (MIP) was computationally designed and synthesized for the selective extraction of metaproterenol (MTP), from human plasma. In this regards semi empirical MP3 and mechanical quantum (DFT) calculations were used to find a suitable functional monomers. On the basis of computational and experimental results, acrylic acid (AA) and DMSO:MeOH (90:10 %V/V) were found to b...
