Development of a Microfluidic-Based Electrochemical Cell for Analyzing Bacterial Biofilms

I. Claydon [1], J. Turner [1], B. Sammakia [1],
[1] Binghamton University, Binghamton, NY, USA

The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of the self-contained microfluidic-based electrochemical cell portion of a multifaceted analysis system is ...

Optimization of Device Geometry of a Fully-Implantable Hearing Aid Microphone

A. Dwivedi [1], G. Khanna [1],
[1] National Institute of Technology Hamirpur, Himachal Pradesh, India

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices provide freedom from the social and practical difficulties of using conventional hearing aids. The paper presents ...

Model Based Stimulus Experiments to Improve Biological Wastewater Treatment Performance

[1] Non-linearity and Complexity Research Group, System Analytics Research Institute, School of Engineering and Applied Science, Aston University, Birmingham, United Kingdom

The municipal wastewater treatment in a sustainable context requires a smart technology in which an optimal combination of the ecological status and energy demand can be achieved. The integration of electron conductive materials into a traditionally constructed wetland (CW) has been demonstrated as an emerging strategy for wastewater treatment [1, 2]. By exploiting the electron transfer ...

In supplying consultancy services, Engineers at BE CAE & Test propose their Customers to use COMSOL Multiphysics® apps to run parametric models and carry-out predictive analyses ...

Effect of KFm Airfoils Application on Aerodynamic Characteristics on the Example of NACA 0012

R. Szczepaniak [1], R. Bąbel [1],
[1] Polish Air Force Academy, Aeronautics Faculty, Deblin, Poland

The paper presents of the application of Kline-Fogleman modified to determine aerodynamic characteristics and flow filed around the exemplary airfoil. This type of airfoil is currently used in models and small unmanned aircraft. Work on the use of this profile in larger aircraft is on-going, however, the increase in Reynolds number requires an active step change in the size of the stairs to ...

Multiphysics Simulations for the Design of a Superconducting Magnet for Proton Therapy

C. Calzolaio [1], H. Carolin [1], S. Stephane [1],
[1] Paul Scherrer Institut, Villigen, Switzerland

The use of proton therapy for cancer treatment shows a growing trend, since the radiation dose delivered to the target volume is maximized and the dose to the surrounding healthy tissues is minimized. To direct the proton beam from all directions to the tumor in the patient, the last part of the beam transport system is mounted on a gantry rotating 360° around the patient. This system consists ...

Optics at the Nanoscale: Merging Nanoparticles with Light

Naomi Halas
Professor of Electrical and Computer Engineering, Chemistry and Bioengineering,
Rice University, Houston, TX, USA

Dr. Naomi Halas is currently Professor of Electrical and Computer Engineering, Chemistry, and Bioengineering at Rice University. She is the inventor of nanoshells, nanoparticles with optical resonances spanning the visible and infrared regions of the spectrum. She is co-founder of a company developing nanoshell-based cancer therapy. She is author of more than 150 refereed publications, more than ...

Electromagnetic Analysis of Cloaking Metamaterial Structures

E. Furlani, and A. Baev
The Institute for Lasers, Photonics and Biophotonics, University at Buffalo, Buffalo, NY, USA

We study cylindrical and spherical shell structures that have cloaking material properties proposed by Pendry et al. We use 2D and 3D time-harmonic analysis to study the field distribution and power flow for various arrangements of these structures. We have shown that the COMSOL RF solver is well suited for the analysis of cloaking metamaterial structures If cloaking material properties can be ...

Magneto-hydrodynamic Flow in Electrolyte Solutions

M. Qin[1], and H. Bau[1]
[1]Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania, Pennsylvania, USA

The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides detailed information on ions’ concentrations. The second model treats the electrolyte as a conductor, and ...

Coupled Heat and Mass Transfer Processes in Enclosed Environments

J.L.Wilson[1], and R. Dwivedi[1]

[1]New Mexico Institute of Mining and Technology, Socorro, New Mexico, USA

Geothermally driven natural convection in enclosures is a ubiquitous process occurring in many physical environments such as caves, mines, etc. We have numerically simulated laminar and turbulent natural convection in isolated air-filled cavities, buried in a more conductive rock mass. We have modeled heat transfer using COMSOL's Convection and Conduction mode. To better understand the ...
