Modeling a plane 3 DOF compliant micromanipulator

Verotti M., University of Rome “La Sapienza”, IT

In the present work, a new MBS (Multi-Body System) code has been dedicated to the static and dynamic analysis of micro-compliant mechanisms. Although the inertial force become more and more negligible, the smaller becomes the [...]

Numerical evaluation of growth conditions of GaN-based LEDs in multiwafer MOCVD reactor

Yang L., Zhang J., Hu J., Shanghai University, CN

In this paper, numerical evaluation of growth conditions of GaN in multiwafer planetary MOCVD reactor was carried out. The growth of GaN films using TMGa as a precursor, hydrogen and nitrogen as carrier gas was [...]

Application of a Nanoclay-Polypropylene Composite to Efficient Vehicle Occupant Safety Countermeasure Design

Deb A., Venkatesh G.S., Karmarkar A.G., Gurumoorthy B., Indian Institute of Science, IN

Polypropylene (PP) which is a thermoplastic polymer is extensively used in various shades and textures for designing interior trim of vehicles for covering metallic body bestowing an aesthetic and pleasing look as well as providing [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

Carbon Nanotube Field Effect Transistor (CNTFET) 2-D Channel Electrostatic Potential Model for TCAD Application

Abebe H., Cumberbatch E., USC, US

A 2-D channel electrostatic potential model of CNTFET is presented. The model is developed by directly solving Laplace’s equation in cylindrical coordinates with appropriate boundary conditions. To the best of our knowledge, the Technology Computer [...]

Calculated Production Yields in Metallofullerene Series

Slanina Z., Akasaka T., Nagase S., Institute for Molecular Science, JP

The paper reports computations for all lanthanoids L on their encapsulation into the only C74 IPR (isolated pentagon rule) cage (L@C74), for Z@C82 based on encapsulation into the IPR C2v C82 cage, and also for [...]

Dissipative Intrinsic Localized Modes in Nano-ferroelectrics

Biswas A., Chowdhury K., Bandyopadhyay A.K., Bhattacharjee A.K., Mandal D., Dumkal Institute of Engg. & Technology, IN

Ferroelectrics are important materials for optical communication and other important areas of applications where discreteness and nonlinearity causes the formation of intrinsic localized modes that can transport energy with the help of the lattice. Based [...]

Smectic structure of Nano Crystalline Cellulose Established by Large-Scale Parallel Molecular Dynamic Simulations

Kadiri Y., Simon D., Picard G., Ahuntsic College, CA

Structural and optical properties of Nano Crystalline Cellulose (NCC) in liquid solutions and in solid films were investigated by large-scale parallel molecular dynamics (MD) simulation using empirical Coulombian interaction potentials. Our calculations give a good [...]

SUGARX: A Online Tool That Bridges the Gap Between Experiment and Simulation

Marepalli P., Li F., Clark J.V., Purdue University, US

We present a pioneering online tool called SugarX that, for the first time, bridges the gap between experiment and simulation. Our tool is available online at nanoHUB.org with remote experimental control and simulation. A web [...]

Numerical Study on the Mixing Performance of Ring-Type Electroosmotic Micromixer with Configurations of Obstacle in the Mixing Chamber

Seo H.S., Kim Y.J., Sungkyunkwan University, KR

Rapid and efficient mixing is important for many microfluidic applications but challenging process in many microfluidic systems that perform complex chemical synthesis and analysis. Most existing microfluidic mixing systems are limited to low Reynolds number [...]
