Simulation of Gravity-Driven Flow Through a Microfluidic Device on a Rocker Platform

B. Srinivasan[1], J. Hickman[1], M. Shuler[2]
[1]University of Central Florida, Orlando, FL, USA
[2]Cornell University, Ithaca, NY, USA

A micropump delivers fluid between different components of a microfluidic device in a controlled manner. The elimination of micropump can reduce the design complexity, simplify fabrication, shrink the device footprint and decrease the set-up time required for the operation of the ... Mehr lesen

CVD Graphene Growth Mechanism on Nickel Thin Films

K. Al-Shurman[1], H. Naseem[2]
[1]The Institute for Nanoscience & Engineering, University of Arkansas, Fayetteville, AR, USA
[2]Department of Electrical Engineering, University of Arkansas, Fayetteville, AR, USA

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very ... Mehr lesen

COMSOL Multiphysics® Simulations of Graphene Chemical Vapor Deposition (CVD) Growth

K. M. Al-Shurman[1], H. Naseem[1]
[1]The Institute for Nanoscience & Engineering, University of Arkansas, Fayetteville, AR, USA

Chemical vapor deposition (CVD) is a promising effective method for synthesis of graphene films. CVD graphene film is obtained from hydrocarbon species such as CH4 through complex catalytic chemical reactions on the surface of the catalyst. Therefore, studying the catalytic reaction ... Mehr lesen

COMSOL Multiphysics® Software: Time-Lapse Electrical Resistivity Inversion

T. K. Chou[1], M. Chouteau[1], M. J. Yi[2]
[1]Department of Civil, Geological & Mining Engineering, École Polytechnique de Montréal, Montreal, QC, Canada
[2]Korea Institute of Geoscience and Mineral Resources, Daejeon, South Korea

Time-lapse electrical resistivity tomography (ERT) method provides a non-invasive way to monitor subtle sub-surface changes caused by water flow such as in an infiltration test. Problems arise when the inversion models contain artifacts due to measurement errors, rapid change in soil ... Mehr lesen

Use of FEM in the Design of an HTS Insert Coil for a High Field NMR Magnet

E. Bosque[1]
[1]Applied Superconductivity Center, National High Magnetic Field Laboratory, Tallahassee, FL, USA

High temperature superconductors (HTS) allow larger current densities through coil wound electromagnets, which produce higher magnetic fields. A high field HTS insert demonstration magnet is being built with high field homogeneity (~1 ppm) for application in nuclear magnetic resonance ... Mehr lesen

Numerical Study of Flux Models for CO2 - Enhanced Natural Gas Recovery and Potential CO2 Storage in Shale Gas Reservoirs

N. Prajapati[1], P. L. Mills[1]
[1]Department of Chemical & Natural Gas Engineering, Texas A&M University, Kingsville, TX, USA

This work encompasses different physics involved in fluid flow in shale gas reservoir. Non-linear equations for fluid flow are solved with COMSOL Multiphysics® PDE module. It focuses on comparing the performance of various species transport flux models by accounting for inter-molecular ... Mehr lesen

Kinetic Parameters for Gas Phase Photocatalysis: Analytic Versus CFD Approach

S. Denys[1], S. Verbruggen[1], S. Lenaerts[1]
[1]Sustainable Energy and Air Purification, Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Introduction Among the advanced oxidation processes (AOPs) for removal of volatile organic compounds (VOCs) from air, photocatalytic oxidation (PCO) is considered a very promising technology [1,2]. PCO can achieve mineralization of harmful VOCs to CO2 and H2O using only UV light [3]. A ... Mehr lesen

DNA Interactions in Crowded Nanopores

K. Misiunas[1], N. Laohakunakorn[1], S. Ghosal[2], O. Otto[1], U. F. Keyser[1]
[1]University of Cambridge, Cambridge, UK
[2]Northwestern University, Evanston, IL, USA

The motion of DNA in crowded environments is a common theme in physics and biology. Examples include gel electrophoresis and the self-interaction of DNA within cells and viral capsids. Here we study the interaction of multiple DNA molecules within a nanopore by tethering the DNA to a ... Mehr lesen
