A Mean Field Approach to Many-particles Effects in Dielectrophoresis

O. Nicotra, and A. La Magna
CNR-IMM Sezione di Catania, Catania, Italy

One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in ... Read More

Computational Modeling of Magnetorheological Elastomers Using Soft and Hard Magnetic Particles

J. Biggs[1], P. VonLockette[1], and S. Lofland[1]
[1]Rowan University, Glassboro, New Jersey

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and ... Read More

Designing B-field Coils from the Inside-Out

C.B. Crawford[1], Y. Shin[1], and G. Porter[1]
[1]Department of Physics and Astronomy, University of Kentucky, Lexington, Kentucky, USA

Traditionally the design cycle for magnetic fields involves guessing at a reasonable conductor / magnetic material configuration, using FEA software to calculate the resulting field, modifying the configuration, and iterating to produce the desired field. Our method involved solving the ... Read More

Development of an On-Line Wall-Fouling Sensor for Pipeline Transportation of Heavy Oil-Water Mixtures

S. Rushd[1], and R.S. Sanders[1]
[1]Chemical & Materials Engineering Department, University of Alberta, Edmonton, AB, Canada

A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... Read More

Electron Trajectories in Scanning Field-Emission Microscopy

H. Cabrera [1],
[1] Swiss Federal Institute of Technology, Zurich, Switzerland

The Scanning Field Emission Microscopy (SFEM) is a novel technology similar to the better known Scanning Tunneling Microscopy (STM). In STM, electrons are exchanged between the outermost atom of a sharp tip and the outermost atom of a target over sub-nanometer distances by means of the ... Read More

Non-linear DC Electrophoresis in High Electric Field Conditions

E. Ruiz-Reina [1], F. Carrique [1],
[1] University of Málaga, Málaga, Spain

Very recently, the synthesis and experimental study of a new class of highly charged polymer particles has been described, which spontaneously charge in non-aqueous low-polarity solvents [1,2]. These suspensions are an example of what is known as salt-free systems. The study of ... Read More

Simulation of Silicon Nanodevices at Cryogenic Temperatures for Quantum Computing

F. A. Mohiyaddin [1], F. G. Curtis [1], M. N. Ericson [1], T. S. Humble [1],
[1] Quantum Computing Institute, Oak Ridge National Laboratory, Oak Ridge, TN, USA

Electronic devices operating at cryogenic temperatures are critical for a wide variety of applications including quantum computing, space, medicine and fundamental research [1]. The design of these devices requires accurate physical modeling of the electric fields, currents, conduction ... 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

Nanofluidic Analyte Preconcentration Using Fluid Field-Effect Diodes

A. Eden [1], K. Scida [1], J. C. T. Eijkel [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California, Santa Barbara, CA, USA
[2] University of Twente, Enschede, Netherlands

Introduction Throughout the field of micro- and nanoscale electrokinetics, floating bipolar electrodes (BPEs) have proven to be useful in manipulating charged ionic species and biomolecules for electroanalytical studies. The growing use of integrated electronics in working towards fully ... Read More

Increasing Dust Removal Efficiency of Electrodynamic Screens Using Frequency Optimization via COMSOL Multiphysics®

C. Morales [1], R. Eriksen [1], M. Horenstein [1], M. Mazumder [1],
[1] Boston University, Boston, MA, USA

Utility-scale photovoltaic (PV) and concentrated solar power (CSP) generation facilities are located in desert environments throughout the world to take advantage of the high availability of sunlight in these areas. Unfortunately, naturally occurring sandstorms in these deserts often ... Read More
