2020-02-20 2020-12-09 Nanotechnology is the study that focuses on processing the materials on the atomic, molecular, and supramolecular scale.In the recent two decades, scientists started developing the capability to control matter at the level of single atoms and small groups of atoms and to characterize the properties of materials and systems at that scale.The importance of nanotechnology is that it will enhance We report on copper adsorption through a self-ordered molecular pattern, namely cyanide-modified Pt(111), in a attempt to develop a procedure with which periodic metallic nanostructured deposits could be fabricated. We show that copper (either in ionic or metallic state) adsorbs on the surface of a cyanide-modified Pt(111) electrode following exactly the molecular pattern.

Atomic Scale Simulation is the most advanced technology; it most applicable on nano-technology, special on nano-tribolgy. A quantitative understanding of the mechanism of charge transport in molecular junctions is not only vital for the future development of functional molecular electronic circuits but can also shed light on the electron transfer reactions in areas such as photochemistry, electrochemistry and catalysis.

It is therefore rather surprising that to the best of our knowledge polyimides have never been studied through atomistic computer simulations on a microsecond time scale.To fill this gap here, we employ microsecond atomic-scale molecular dynamics (MD) simulations to get insight into the structural and thermal properties of heat-resistant bulk polyimides.

We employ microsecond atomic-scale molecular dynamics simulations to get insight into the structural and thermal properties of heat-resistant bulk polyimides. As electrostatic interactions are essential for the polyimides considered, we propose a two-step equilibration protocol that includes long (microsecond-scale) MD simulations of polymer melt with partial atomic charges switched off Standard molecular dynamics algorithms, based upon solving Newton’s equations, are limited by the femtosecond time scale of atomic vibrations. EON simulations are designed for rare event systems where the interesting dynamics can be described by fast transition between stable states. 1999-01-01 · Molecular dynamics simulation of friction on the atomic scale .
