Nano Crystalline Cellulose – Optical and Structural Properties by Molecular Dynamic Simulations

Kadiri Y., Simon D., Picard G., Ghozayel F., Lebreux J.-D., Ahuntsic College, CA

Structural and optical properties of Nano Crystalline Cellulose (NCC) in liquid solutions and in nematic films were investigated by large-scale molecular dynamics (MD) simulation using empirical Coulombian interaction potentials. The latter was modified by taking [...]

The Concatenation of the Concurrent Self-replication and Self-organization Processes

Wegrzyn S., Znamirowski L., Silesian University of Technology, PL

In the paper the concatenation of the concurrently running two self-replication processes and concurrently running self-replication and self-organization processes has been analyzed and discussed. Basing on the simulation, there was possible to predict the behavior [...]

Facile Assembly of Nanoparticles into 2D Micro-structured Films by a Polymer-aided Self-organization Process

Nurmawati M.H., Ajikumar P.K., Renu R., Valiyaveettil S., National University of Singapore, SG

There have been many reported approaches for tailoring the properties of nanomaterials by manipulating the way in which they order on several different length scales. The self-assembly of micro- and nano-structures in periodic arrangement of [...]

Biomimetic Molecules as Building Blocks for Synthetic Muscles – A Proposal

Flood A.H., Badjic J., Han J-Y, Pentecost C., Northrop B.H., Cantrill S.J., Houk K.N., Stoddart J.F., UCLA and CNSI, US

Biomolecular motors are natures machines that convert chemical energy into mechanical work. The performance and scale of these systems are believed to derive from their precise positioning and alignment into organized hierarchical levels at the [...]

Surface Shaping by Ion Beams at Grazing Incidence: Simulations vs. Experiment

Stepanova M., Dew S.K., University of Alberta, CA

Miniaturization of electronic technologies highlights special approaches such as selforganization of nanostructures. Particularly, surface etching by ion beams at grazing incidence is of interest for applications, because it provides pronounced submicron size, self-organized ripples. Formation [...]

Numerical Simulation of Periodical Distribution of Antisite Defects in Irradiated Semiconductors

Mykhaylovskyy V.V., Russell K.C., Sugakov V.I., Academy of Science of Ukraine, UA

A simulation of radiation-induced instability in binary semiconductors, such as GaAs, was fulfilled. The instability is connected with antisite defects accumulated. It was shown that the number of antisite defects in crystal under irradiation can [...]
