Sample Preconcentration in Channels with Nonuniform Surface Charge and Thick Electric Double Layers

A. Eden [1], C. McCallum [1], B. Storey [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California Santa Barbara, Santa Barbara, CA, USA
[2] Olin College, Needham, MA, USA

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... Mehr lesen

Comparison of User vs. COMSOL® Developed Automated Installation Verification of COMSOL Multiphysics® Software

M. W. Crowell [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Verifying that a local software installation performs as the developer intended is a potentially time consuming but necessary step for safety related codes. Automating this process not only saves time, but can increase reliability and scope of verification compared to ‘hand’ comparisons. ... Mehr lesen

Optimization of a Thermoelectric Conversion System

J. R. Chase [1],
[1] Alphabet Energy, Hayward, CA, USA

Thermoelectric materials have no theoretical limit to conversion efficiency of heat into electrical power. In order to compete with other forms of power generation and small-scale energy conversion, thermoelectric converters need to maximize their practical usability when integrated with ... Mehr lesen

Simulating Spiking Neurons Using a Simple Mathematical Model

S. Kirigeeganage [1], J. Naber [1], D. Jackson [1], R. Keynton [1], T. Roussel [1],
[1] University of Louisville, Louisville, KY, USA

This paper utilizes COMSOL Multiphysics® software and the Application Builder to simulate neurological responses in nerve axons due to external electrical stimuli. The AC/DC Module of the COMSOL® software is first used to solve the Maxwell's equations. Then the results from the Maxwell's ... Mehr lesen

Modeling of a Diffraction Grating Coupled Waveguide Based Biosensor for Microfluidic Applications

Y. Wu [1], M. L. Adams [1],
[1] Auburn University, Auburn, AL, USA

Grating couplers are a common optical component for introducing light into chip-based photonic structures. They are used extensively for optical interconnects and optical device integration. A microfluidic diffraction grating coupled waveguide (MDGCW) biosensor applies a grating coupler ... Mehr lesen

Using COMSOL Multiphysics® Software for Benchmarking Problems in Cell Migration

M. Nickaeen [1], I. L. Novak [1], A. Mogilner [2], B. M. Slepchenko [1],
[1] Richard D. Berlin Center for Cell Analysis and Modeling, University of Connecticut Health Center, Farmington, CT, USA
[2] Courant Institute and Department of Biology, New York University, New York, NY, USA

A recently published conservative algorithm for simulating reactions and transport in moving domains have been extended to models in which cell kinematics are coupled with intracellular dynamics. For this, the method that combines a Eulerian approach with tracking an explicit boundary ... Mehr lesen

Design of a Self-Recharging Untethered Mobile Inspection Tool inside a Pipeline

W. Chalgham [1], A. C. Seibi [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... Mehr lesen

Simulating Fluid Flow through a Culture Chip for Cell Migration Studies in Microgravity

A. Dhall [1], T. Masiello [1], L. Butt [1], M. Strohmayer [1], M. Hemachandra [1], N. Tokranova [1], J. Castracane [1],
[1] Colleges of Nanoscale Science and Engineering, SUNY Polytechnic Institute, Albany, NY, USA

Exposure to microgravity is known to alter genomic and proteomic expression and suppress immune cell activity. These changes may influence cancer development. Studying cancer cells in this environment, may help uncover novel therapeutic targets. SUNY Polytechnic Institute and ... Mehr lesen
