Toward Nano-Scale Scanning Electrochemical Microscopy of Single Live Cells by Means of the COMSOL Multiphysics® software

Z. Ding [1], F. P. Filice [1], M. S. M. Li [1],
[1] Department of Chemistry, University of Western Ontario, London, ON, Canada

Scanning Electrochemical Microscopy (SECM) is a powerful noninvasive analytical technique employed in a variety of applications ranging from electrochemical characterization of material surfaces, to bioanalytical characterization of single live cells [1]. When applied to live cells, SECM ... Mehr lesen

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Mehr lesen

Fast Charging Strategy Optimization based on Electrochemical Model and Dynamic Programming for a Lithium-ion Battery Cell

M. Xu [1] , X. Wang [1]
[1]Department of Mechanical Engineering, Oakland University, Rochester, MI, USA

Fast charging of lithium-ion batteries is critical to commercial application of electrical vehicles (EV). Recharging lithium-ion batteries using standard charging methods usually takes more than one hour which is considerably longer than refueling an internal-combustion-engine (ICE) car. ... Mehr lesen

Design of an Electro-Osmotic Microfluidic Mixer

T. Eppes [1], I. Milanovic [1], S. Keilich [1],
[1] University of Hartford, West Hartford, CT, USA

This paper explores the performance of a microfluidic mixer that uses a sinusoidal electric field to accelerate the diffusion process between two Newtonian liquid species in an electrolytic solution. The 2D model was developed using the Microfluidics module in the COMSOL Multiphysics® ... Mehr lesen

Simulation and Design of Lithium Ion Battery Packs for the Altitude Conditions in Northern Chile

A. Mallco Carpio [1], M. Cortes Carmona [1],
[1] University of Antofagasta, Antofagasta Energy Center, Antofagasta, Chile

One of the most noticeable effects in loss of performance and capacity of thermal systems is produced by altitude. This causes that the density of a compressible fluid and the atmospheric pressure are considerably reduced, causing a decrease in electrical power and thermal systems. Given ... Mehr lesen

Uncertainty Assessment and Sensitivity Analysis of Heat Generation within a Lithium-Ion Battery

G. Liebig [1], G. Gupta [1], K. Derendorf [1], C. Agert [1],
[1] DLR Institute of Networked Energy Systems, Oldenburg, Germany

Dedicated work in modeling, simulation and design optimization of Lithium-ion Battery (LIBs) was done in the past decades, and still, the most widely used one for electrochemical processes is the Newman model. [1] The underlying parameters are treated deterministically, but the impact of ... Mehr lesen

Modeling and Simulation of Redox Titration of Metal Oxides at Porous Microelectrodes

L. Balboa [1], M. Hänsch [1] , J. Behnken [1], G. Wittstock [1],
[1] Institute of Chemistry, Carl von Ossietzky University of Oldenburg, Oldenburg, Germany

In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... Mehr lesen

2-D Modeling of CO2 Electrolysis Using Gas Diffusion Electrode Operate at Neutral pH and Mild Conditions

A. Monteverde Videla[1], N. Vasile[1], G. Saracco[1]
[1] Istituto Italiano di Tecnologia, Centre for Sustainable Future Technologies, Turin, Italy

CO2 capture and further conversion into valuable products can be a promising solution against global warming. Normally, CO2 conversion can be achieved by chemical methods, by photocatalytic and electrocatalytic reduction [1]. Specifically for electrocatalytic reduction of CO2, challenges ... Mehr lesen
