CdS Thin Film Transistor Threshold Voltage Shift Investigation

W. Wondmagegn [1],
[1] Frostburg State University, Frostburg, MD, USA

A threshold voltage shift of CdS Thin Film Transistor is studied using the COMSOL Multiphysics® software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a single-crystal device except that traps and ... Read More

Flotation Height in 'Air Hockey' Spatial Atomic Layer Deposition

J. Grasso [1], B. Willis [1],
[1] Department of Chemical and Biomolecular Engineering, University of Connecticut, Storrs, CT, USA

Atomic layer deposition(ALD) is one proven method to deposit ultra-thin films. ALD is advantageous for its atomic-level thickness control and conformity; leading to high quality films. Slow deposition rates for conventional ALD contribute to the impracticality of utilization of this ... Read More

Simulation of Magnetically Driven Peristaltic Pumps for Microfluidic Applications

L. Gritter [1], J. Crompton [1], K. Koppenhoefer [1], P. Nath [2]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Applied Modern Physics, Los Alamos National Lab, Los Alamos, NM, USA

Microfluidic technologies can enable laboratory processes to be packaged in miniaturized and automated systems, allowing these processes to be performed with hand-held devices outside a laboratory environment. The practical usefulness of these “lab on a chip” systems has often been ... Read More

Finite element analysis approach for optimization of enzyme activity for enzymatic bio-fuel cell

C. Wang[1], Y. Song[1], Y. Parikh[1], and J.H. Yang[1]
[1]Department of Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, 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, we focused on a three dimensional EBFC chip with highly dense micro-electrode arrays, fabricated by ... Read More

Fluid Dynamics of Blood Flow during Reperfusion and Post-conditioning

T. Merrill[1], A. La Barck[1], and J. Docimo[2]
[1]Rowan University, Glassboro, New Jersey, USA
[2]FocalCool, LLC, Mullica Hill, New Jersey, USA

Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies ...

Simulation of Electromagnetic Enhancement in Transition Metamaterials using COMSOL

I. Mozjerin[1], T. Gibson[1], and N.M. Litchinitser[1]
[1]Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, New York, USA

Metamaterials are a new class of artificial materials, which possess various unusual properties. One of these properties is a negative index of refraction produced by setting both the dielectric permittivity ε and the magnetic permeability μ of the material less than zero. ... Read More

Expanding Your Materials Horizons

R. Pryor[1]
[1]Pryor Knowledge Systems, Inc. (COMSOL Certified Consultant), Bloomfield Hills, Michigan, USA

Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... Read More

[1]Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery ... Read More

Including Expert Knowledge in Finite Element Models by Means of Fuzzy Based Parameter Estimation

O. Krol[1], N. Weiss[1], F. Sawo[1], and T. Bernard[1]

[1]Fraunhofer Institute for Information and Data Processing, Karlsruhe, Germany

In this paper we present a novel approach for modeling spatial distributed bio- chemical and environmental processes like the growth of plants and the related biochemical reactions. The physical phenomena like flow and mass transport can be described by fluid dynamics equations, but for ... Read More
