Modelling of a Single Cardiomyocyte Interaction with a Microcantilever Using COMSOL Multiphysics®

I. Banerjee[1]
[1]Tampere University of Technology, Tampere, Finland

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... En savoir plus

Modeling of Silicon Transport into Germanium Using a Simplified Crystal Growth Technique

F. Mechighel[1][3], B. Pateyron[1], M. El Ganaoui[1], S. Dost[2], and M. Kadja[3]

[1]Laboratory SPCTS UMR CNRS, ENSCI, Limoges University, Limoges, France
[2]Crystal Growth Laboratory, Department of Mechanical Engineering, University of Victoria, British Columbia, Victoria, Canada
[3]Department of Mechanical Engineering, University of Constantine, Constantine, Algeria

A numerical simulation study, using COMSOL Multiphysics®, was carried out to examine the temperature and concentration fields in the dissolution process of silicon into germanium melt. This work utilized a simplified configuration which may be considered to be similar material ... En savoir plus

CVD Graphene Growth Mechanism on Nickel Thin Films

K. Al-Shurman[1], H. Naseem[2]
[1]The Institute for Nanoscience & Engineering, University of Arkansas, Fayetteville, AR, USA
[2]Department of Electrical Engineering, University of Arkansas, Fayetteville, AR, USA

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very ... En savoir plus

Equation Based Heat and Mass Transfer in Porous Media

S. Pemberton[1], K. Ekici[1], R. Arimilli[1]
[1]The University of Tennessee, Knoxville, TN, USA

Perspiration during intense physical activity is an essential part of human thermoregulation. Clothing affects the cooling rate of the body. Heat and water vapor are coupled through evaporation and transported through the fabric. A model of the above system was developed for fabrics of ... En savoir plus

COMSOL Multiphysics-Based Exploratory Insulin Secretion Model for Isolated Pancreatic Islets

P. Buchwald
University of Miami, Miami, FL, USA

Insulin released by the beta-cells of pancreatic islets is the main regulator of glucose homeostasis, hence, insulin secretion models are of considerable interest for many possible applications. Building on our previous oxygen consumption and cell viability model for avascular islets of ... En savoir plus

Designing and Simulating the Performance Analysis of Piezoresistive Fluid Flow Pressure Sensor

K. PraveenKumar[1], P. Suresh[1], K. Subash[1], M. Alagappan[1], A. Gupta[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India.

In this work, we present the performance analysis of novel micro machined Piezoresistive fluid flow pressure sensor using COMSOL Multiphysics. The principle of the sensing mechanism is based on the deflection of four sensing layers embedded on a thin membrane. The fluid passes through ... En savoir plus

Numerical Modeling of the Bistability of Electrolyte Transport in Conical Nanopores

H. White[1], L. Luo[1]
[1]Department of Chemistry, University of Utah, Salt Lake City, UT, USA

A characteristic feature of nanochannels is that surface properties (e.g., electrical charge) play a more significant role in the transport of fluid and electrolyte. Two oppositely directed flows (electroosmotic flow and pressure-driven flow) determine the flow profile at the nanopore ... En savoir plus

Transport Phenomena in the Conversion of an Anaerobic Landfill into an Aerobic Landfill

H. Omar [1], S. Rohani [1],
[1] University of Western Ontario, London, ON, Canada

The world’s landfills are beginning to fill up due to the growing human population. Landfills require land and there will come a time when there will be no land to be used for landfills. A solution that is gaining attraction is the conversion of traditional “dry-tomb” landfills (used for ... En savoir plus

Flow Simulation In A Submerged Membrane Bioreactor At Laboratory Scale

Y.M. Carreño-Martinez, J.M. Gozalvez-Zafrilla, J.A. Mendoza-Roca, and A. Santafé-Moros
Universidad Politecnica de Valencia, Spain

Submerged membrane bioreactor (SMBR) is an efficient technology for wastewater treatment that combines biological process and membrane filtration in one single stage. In the most usual configuration, submerged membrane hollow fibers are set in several planes. Air is introduced from the ... En savoir plus

Surface Acoustic Wave Properties (SAW) and Acoustic Streaming Characterization for Annular and Curved Electrodes on 128˚ Y-Cut, X-Propagating LiNbO3

G. Potter[1], N. Tokranova[1], S. Gattu[1], J. Castracane[1]
[1]SUNY College of Nanoscale Science and Engineering, Albany, NY, USA

Microfluidic devices and lab-on-a-chip (LOC) require the ability to transport or pump reagents or reaction products, the ability to effectively mix small volumes of fluid, and provide direct data display. Surface acoustic wave (SAW) driven acoustic streaming generated by a piezoelectric ... En savoir plus
