Simulating 200 kHz AC Tumor-Killing Fields with COMSOL Multiphysics®

K. W. Carlson [1], N. Paudel [2], S. Dokos [3], J. A. Tuszynski [4],
[1] Beth Israel Deaconess Medical Center - Harvard Medical School, Boston, MA, USA
[2] IEEE, Greenville, NC, USA
[3] University of New South Wales, Sydney, NSW, Australia
[4] University of Alberta, Edmonton, AB, Canada

Alternating 200 kHz electric fields ~2 V/cm (Tumor Treating Fields, ‘TTFields’) kill cancer cells by disrupting the delicate orchestration of chromosome spindle formation, but the exact mechanism of action is unknown. The likely suspects are polarized intracellular molecules such as ... Read More

Elucidating the Mechanisms of Charge and Temperature Modulated Ionic Transport in Nanochannels

G. Zhang [1], Y. Zhao [1],
[1] Department of Biomedical Engineering, University of Kentucky, Lexington, KY, USA

The transport of fluid through nanochannels is of importance in a variety of technological applications, including biological sensing, energy storage and conversion, chemical separation and many others. Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... Read More

Comprehensive Numerical Modeling of Filamentary RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... Read More

Time-dependent Thermoelectric Switching in Vanadium Oxide

G. Àbel [1], F. Torres [1], M. Kiwi [1],
[1] Universidad de Chile, Santiago, Región Metropolitana, Chile

We report the reversible thermoelectric switching [1, 2, 3] induced by a time dependent and frequency domain electric field (or AC voltage) in a microscopic single contact nano-device based on Gold and Vanadium Oxide, which promises potential applications for future information storage ...

The Effect of Aluminum Content on Convective Flow of Molten Metal Generated by Arc Plasma

Y. T. Cho [1], C. K. Kim [1], H. U. Hong [1],
[1] Changwon National University, Changwon, Gyeongsangnam-do, South Korea

Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... Read More

Steady-State and Transient Electrothermal Simulation of Microheater for Gas Sensing

A. N. Radwan [1], M. Mehregany [1],
[1] Case Western Reserve University, Cleveland, OH, USA

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...

Simulating Specular Reflectance in Solar Cleaning Films using the Particle Tracing Module of the COMSOL Multiphysics® Software and LiveLink™ for MATLAB®

J. Bone [1], C. Morales [1], R. Eriksen [1], M. Mazumder [1], M. Horenstein [1],
[1] Electrical and Computer Engineering, Boston University, Boston, MA, USA

One of the obstacles preventing photovoltaic and concentrated solar power technologies from scaling up to meet increasing electricity demands is the inevitable dust accumulation on the optical surfaces of solar collectors. The ideal location for solar power is arid environments due to ... Read More

Several Hydrodynamic Instabilities Illustrated Using the COMSOL Multiphysics® Software

C. F. Ivory [1],
[1] Washington State University, Pullman, WA, USA

The COMSOL Multiphysics® software has proved itself an invaluable tool for teaching "Transport Phenomena" to graduate and undergraduate engineers. In particular, the software allows us to visualize and explore solutions well beyond what students could do with pencil and paper. For ... Read More

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 ... Read More

Modeling the Electric Double Layer in Finite Electrolyte Solutions

J. C. Woehl [1],
[1] University of Wisconsin - Milwaukee, Milwaukee, WI, USA

While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ... Read More
