Interaction of Coupled Particles Based on Lennard-Jones and Spring Forces in Brownian Ratchet Devices

Retkute R., Gleeson J.P., University College Cork, IE

Electrophoresis is a technique used to separate polyelectrolyte strands of different lengths. One of its fields of application in nanotechnology is in the separation of DNA. Chains of particles can undergo net transport on a [...]

Coupled Multiphysics Modeling of Semiconductor Lasers

Sikorski Z., Jiang Y., Czyszanowski T., Przekwas A., Turowski M., CFD Research Corporation, US

Comprehensive models of semiconductor lasers are required to predict realistic behavior of various laser devices for the spatially nonuniform gain that results due to current crowding. Nonuniform gain has visible effect on laser dynamics and [...]

A Mixed Rigid/Elastic Formulation for an Efficient Analysis of Electromechanical Systems

Ramaswamy D., Aluru N.R., White J.K., Massachusetts Institute of Technology, US

In this paper we describe both how to extract rigid bodies given an input file of elements, and how to efficiently construct and solve the rigid-elastic system of equations. Results are given to demonstrate that [...]
