Study of Electrochemically Generated Two-Phase Flows

J. Schillings [1], O. Doche [2], J. Deseure [1],
[1] LEPMI, Grenoble, France
[2] SIMAP, Grenoble, France

The dependency of electrochemical processes performances on mass transfer is well-known. Electrolyte flow in the vicinity of electrodes surface can enhance reactions due to increased mass transfer. This flow can be generated by the production of a gaseous phase, leading to a natural ... Read More

Analysis of a Plasma-Mediated Photoacoustic Response From Plasmonic Nanoparticles in Ultrashort Regime

A. Hatef [1], B. Darvish [1], A. Dagallier [2], C. Boutopoulos [2], M. Meunier [2],
[1] Nipissing University, North Bay, ON, Canada
[2] École Polytechnique de Montréal, Montréal, QC, Canada

Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications [1]. Such functionality is due to the localized surface plasmon resonance (LSPR) ... Read More

Mitigation of Greenhouse Gas Leakage from Oil and Gas Wells

J. S. Crompton [1], H. Spencer [2], J. Thomas [1], K. Koppenhoefer [1]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Seal Well, Calgary, AB, Canada

Pre-existing oil and gas wells and well bores represent highly permeable pathways for leakage of greenhouse gases; in Alberta alone leaks have been estimated to provide the equivalent of 3.5 million tonnes of CO2 per annum. In addition to abandoned wells without plugs, gas leakage may ... Read More

A Strategy to Simulate Radio Frequency Heating Under Mixing Conditions

S. Wang [1], L. Chen [1],
[1] Northwest A&F University, Yangling, Shaanxi, China

A computer simulation model was developed using finite element-based commercial software, COMSOL Multiphysics®, to simulate temperature distributions in wheat samples packed in a rectangular plastic container and treated in a 6 kW, 27.12 MHz RF system with and without mixing conditions. ...

Auto assembled Ag-ZnO [1] star shaped nanostructures depicted in figure 1, presents their natural electromagnetic resonance at 60 THz. In this work we present that is possible to change this value by covering it with a variable in thickness layer of gold. The analysis is performed by ... Read More

Structural Design of a NFC-Reader-Antenna for Automotive Electronics with FEM Simulation

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, ZF-Friedrichshafen AG. Group, Friedrichshafen, Germany

The design of a right contour/structure of the NFC-antenna is presented. The NFC-reader-antenna is applied later to communicate with the NFC-tag (transponder) of a smart phone placed in the phone box of the car. The NFC-reader-antenna with selected contour is printed directly on the PCB ... Read More

Determination of NFC-Antenna Operating Distance by COMSOL Multiphysics® Simulation of Planar Transformer Modeling

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, Espelkamp, Germany

Although the Near Field Communication (NFC) concept has been developed for the short distance communication between the NFC-reader antenna and transponder/Tag, yet the requirements of different Automotive OEMs vary drastically. For instance, for the keyless entry into the car based on ... Read More
