A Model of a Horizontal Atmospheric Pressure Chemical Vapor Deposition Reactor

T. Adams

Naval Surface Warfare Center Crane Division, CRANE, IN, USA

A model of a horizontal atmospheric pressure chemical vapor deposition reactor was implemented to aid in the design of a laboratory based one. The model coupled momentum transport, energy transport, and mass transport phenomena to account for reacting fluid flow of a compressible gas in ... Per saperne di più

Multiphysics Modeling of an Ion Mobility Spectrometer

T. Adams, and J. Fulton

Naval Surface Warfare Center, Crane Division, Crane, IN, USA

In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field." The production of the ... Per saperne di più

Computational Analysis of the Mechanical and Thermal Stresses in a Thin Film PProDOT-Based Redox Capacitor

J. Sotero-Esteva[1], M. Rosario-Canales[2], P. Gopu[3], and J. Santiago-Avilés[3]

[1]Department of Mathematics, University of Puerto Rico at Humacao, Humacao, PR
[2]Department of Chemistry, University of Pennsylvania, Philadelphia, PA, USA
[3]Department of Electrical and Systems Engineering, University of Pennsylvania, Philadelphia, PA, USA

Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like ... Per saperne di più

AC/DC Modeling and Experimental Impedance Verification of 3D MEMS Inductor Coils

T. Reissman, and E. Garcia
Sibley School of Mechanical and Aerospace Engineering, Cornell University, Ithaca, NY, USA

In this work, an analysis is presented for a 3-dimensional RF MEMS coil using the COMSOL AC/DC module in conjunction with the CAD import module. The realization of being able to produce such 3-dimensional RF coils allows for less surface area to be needed for similar inductor performance ... Per saperne di più

Modeling Joule Heating Effect on Lunar O2 Generation via Electrolytic ...

Modeling Joule Heating Effect on Lunar O₂ Generation via Electrolytic Reduction

J. Dominguez[1], S. Poizeau[2], and L. Sibille[1]

[1]ASRC Aerospace Corporation, Kennedy Space Center, Fl, USA
[2]Massachusetts Institute of Technology, Cambridge, MA, USA

Kennedy Space Center is leading research work on lunar O2 generation via electrolytic reduction of regolith. The metal oxide present in regolith is dissociated into oxygen anions and metal cations leading to the generation of gaseous oxygen at the anode and liquid metal at the cathode. ...

Temperature Excursions at the Pulp-Dentin Junction during the Curing of Light-Activated Dental Restorations

M. Jakubinek[1,2], C. Neill[1], C. Felix[3], R. Price[2,3], M. White[1,2]

[1]Departments of Chemistry and Physics, Dalhousie University, Halifax, NS, Canada
[2]Institute for Research in Materials, Dalhousie University, Halifax, NS, Canada
[3]Department of Dental Clinical Sciences, Dalhousie University, Halifax, NS, Canada

Heat produced during the curing of light-activated dental restorations could damage the dental pulp. Given the prevalence of composite restorations and the importance of avoiding injury to the pulp, efforts should be made to minimize the temperature increase that occurs at the pulp ...

Magnetic Particle Buildup Growth on Single Wire in High Gradient Magnetic Separation

F. Chen
Department of Chemical Engineering, M.I.T., Cambridge, MA, USA

Magnetic fluids containing nano or submicron magnetic particles and their application in food, biological and pharmaceutical systems have recently attracted increasing attention. Magnetic particles can be collected efficiently in magnetizable matrices (e.g. iron wires) in high gradient ... Per saperne di più

Using COMSOL Multiphysics for Modeling of Musculoskeletal Biomechanics

R. L. Spilker
Department of Biomedical Engineering, Rensselaer Polytechnic Institute, New York, USA

In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft ...
