Finite Element Modeling a Redox-Enzyme-Based Electrochemical Biosensor

Y. Huang[1], and A. Mason[1]
[1]Electrical and Computer Engineering, Michigan State University, East Lansing, Michigan, USA

This paper describes the modeling of an electrochemical biosensor embedded in a microfluidic channel to determine the concentration of a target biomolecule. The total amount of analyte in the sample can be calculated by integrating the analyte concentration over the duration of the peak ... En savoir plus

Coupled Electromagnetics-Multiphase Porous Media Model for Microwave Combination Heating

V. Rakesh, and A. Datta
Dept. of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics ...

[1]Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari, Italy
[2]Department of Civil Engineering, Environmental and Architecture, University of Cagliari, Cagliari, Italy

In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and ... En savoir plus

Fluid Flow and Current Density Distribution in Large-area HT PEMFCs

G. C. Bandlamudi[1,2], C. Siegel[2], C. Heßke[1], and A. Heinzel[1,2]
[1]ZBT Duisburg, Duisburg, Germany
[2]University of Duisburg-Essen, Duisburg, Germany

High temperature polymer electrolyte membrane fuel cells (HT PEMFCs) are very promising technologies when used in combined cooling and heating power (CCHP) systems. They are operated at 160°C, offering the possibility of high tolerance to fuel impurities and a possibility to use the heat ... En savoir plus

Radiofrequency Inductive Coupled Plasmas Towards Low Pressure

M. Cavenago
Laboratori Nazionali di Legnaro
INFN
Legnaro, Italy

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... En savoir plus

Multiphysics Simulation of an Ultrasonic Piezoelectric Motor

P. Carvalho [1], C. Nycz [1], K. Gandomi [1], G. Fischer [1],
[1] Worcester Polytechnic Institute, Worcester, MA, USA

Operation in strong magnetic fields, vacuum or high precision positioning has often surpassed the limits of traditional actuators. Piezoelectric motors provide a suitable alternative in these applications where non-ferromagnetic based construction or low inertia may be required. We ... En savoir plus
