Finite Element Analysis Approach for Optimization of Enzyme Activity for Enzymatic Bio-fuel Cell

Y. Song, and C. Wang
Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are miniature, implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study using COMSOL Multiphysics, we use an EBFC chip, having three dimensional, highly dense micro-electrode ... Read More

Optimizing Bio-Inspired Flow Channel Design on Bipolar Plates of PEM Fuel Cells

X. Wang[1], J. Peitzmeier [2], and S. Kapturowski[3]
[1]Oakland University, Rochester, MI, USA
[2]Michigan Technological University, Houghton, MI, USA
[3]The State University of New York at Buffalo, Buffalo, NY, USA

The flow channel design on bipolar plates affects proton exchange membrane (PEM) fuel cell performance by influencing reactant distribution and water removal in an operating fuel cell. The fuel cell performance can be improved by varying the type, size, or arrangement of channels. Two ... Read More

Mixers and Pumps for Microfluidic Systems, based on Conducting Polymer Oxidation Wave

K. Kannappan, G. Bogle, J. Travas-Sejdic, and D.E. Williams
University of Auckland, Auckland, New Zealand

Electrochemically-active conducting polymers (ECP) swell or shrink in response to ion and solvent incorporation or ejection as a result of electrochemical reaction of the polymer. When anodic potential is applied to an electrode attached to one end of ECP strip, the oxidation process ... Read More

Simulating the Electrical Double Layer Capacitance

G. Zhang
Clemson University, Clemson, SC, USA

When a solid surface makes contact with a liquid medium, an electrical double layer (EDL) structure forms spontaneously through thermodynamic interaction between electrons and ions. In this study, we developed a computational model using commercial finite element analysis package COMSOL ... Read More

Characterization of an AlGaN/GaN Electrostatically Actuated Cantilever Using the Finite Element Method

N. DeRoller, M. Qazi, J. Liu, and G. Koley
University of South Carolina, Columbia, SC, USA

AlGaN/GaN heterostructures are unique because the 2DEG at the interface is created by the difference in polarization properties of the AlGaN and the GaN layers; not due to intentional doping. In this work, a 3D model of an electrostatically actuated micro cantilever has been developed ... Read More

Modeling Thickness Shear Mode Quartz Sensors for Increased Downhole Pressure & Temperature Applications

G.R. Kirikera, W. Patton, and S.M. Behr
Geophysical Research Company LLC, Tulsa, OK, USA

Numerous sensors based on various sensing principles are used to measure pressures and temperatures in wellbores. Of all these sensors, piezoelectric quartz is the most preferred means of sensing pressure and temperature and is probably the only sensor to meet stringent downhole ... Read More

Modeling Energy Harvesting From Membrane Vibrations in COMSOL

R.K. Kapania, R.C. Singh, and C. Sultan
Virginia Polytechnic Institute and State University, Blacksburg, VA, USA

This paper presents an ongoing effort, motivated by developing self-contained sensors for structural health monitoring of inflatable structures, to model the process of extracting useable electrical power from the mechanical vibrations of thin, prestressed membrane structures. Energy ... Read More

Exploiting New Features of COMSOL Version 4 on Conjugate Heat Transfer Problems

J.D. Freels[1], I.T. Bodey[2], and R.V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]University of Tennessee, Knoxville, TN, USA

Recent new releases of COMSOL provide the user with a dramatic new interface from which to interact, and many new features “under the hood” for solving problems more efficiently and with even greater accuracy and consistency than before. This paper will explore several of these new ... Read More

Reliability Testing for the Next Generation of Microelectronic Devices

J. Plawsky, W. Gill, M. Riley, J. Borja, and B. Williams
Rensselaer Polytechnic Institute, Troy, NY, USA

Understanding and predicting the reliability of new generations of high and low-k dielectrics is increasingly important for gate oxides and interlayer dielectrics as both films have become thinner and scaling of device operating voltages has not kept pace with the decrease in the size of ...

Numerical Modeling of Falling Aluminum Particle Oxidation in Air

A. Davidy
Israel Military Industry, Ramat-Hasharon, Israel

Because of its high enthalpy of combustion, aluminum has been added to energetic materials. In this paper, a two dimension thermal model is developed and assessed to describe the interrelated processes of Aluminum particle oxidation by using the software COMSOL Multiphysics. The thermal ...
