CFD-Assisted Design and Optimization of a Pharmacokinetic Microfluidic System

Moeini Sedeh M., Khodadadi J.M., Hong J.W., Cramer K.A., Hamon M., Auburn University, US

In this research, a microfluidic system was designed and optimized to carry out in vitro pharmacokinetic studies of drug candidates in the liver. Computational fluid dynamics (CFD) was called on to assist in the system [...]

Synthesis and Optimization of Metallic nanofluids using Electrical Explosion of Wire in Liquids

Park E.J., Park H-W., Park E.J., Park H-W., Ulsan National Institute of Science and Technology (, KR

This study has been focusing on controlling the size, oxidation, and agglomeration of the nanoparticle by adjusting the plasma of EEWL and the base fluid, including water, ethylene glycols, oil, polymeric solution and other common [...]

Optimization study of Supercapacitor electrode material composition and thickness for enhanced performance of the Supercapacitor

Ranade A.P., Jung D.Y., Sammakia B.G., Eilertsen T., Davis T., Binghamton University, US

A prototype electrode was constructed to verify the optimization of composition of materials for the supercapacitors. Surface area analysis and SEM images were used initially to select the most appropriate active carbon from a group [...]

Geospatial Analysis and Optimization of Fleet Logistics to Exploit Alternative Fuels and Advanced Transportation Technologies

Sparks W., Nationl Renewable Energy Laboratory, US

Today's fleet managers are faced with new challenges posed by government mandates and private-sector goals that include reducing petroleum use, reducing greenhouse gas (GHG) emissions, and—for federal and other government fleets—complying with alternative-fuel mandates. Choosing [...]

Optimizing Multiscale Networks for Transient Transport in Nanoporous Materials

Nilson R.H., Griffiths S.K., Sandia National Laboratories, US

Hierarchical nanoporous materials afford the opportunity to combine the high surface area and functionality of nanopores with the superior charge/discharge characteristics of wider transport channels. In the present paper we optimize the apertures and spacing [...]

Design Optimization of Field Emission from a Stacked Carbon Nanotube Array

Roy Mahapatra D., Sinha N., Melnik R., Yeow J.T.W., University of Waterloo, CA

Field emission (FE) from carbon nanotubes (CNTs) grown on a cathode substrate is difficult to characterize using simple formulae or data fitting, which is due to (1) electron-phonon interaction (2) electromechanical force field leading to [...]

Study of Thermal Efficiency Optimization in a Twin-bubble MEMS Micro-injector

Tang H-K, Tseng F-C, Wang W.W., Lee C-K, Lee I.Y., Lee K., Lee C-K, Lee I.Y., Lee K., Lee C-K, Lee I.Y., Lee K., BenQ Corporation, TW

In this paper, the methodology of design optimization to achieve optimal thermal efficiency of a twin bubble MEMS micro-injector is reported. This twin bubble back shooting structure can reduce the problems of crosstalk and satellite [...]

Monte Carlo Algorithm for Nanoscale Electro-Thermal Optimization

Skorek A.W., Ble S.V., Anders G., Nazarko J., University of Quebec at Trois-Rivieres, CA

In this paper, we will present a Monte Carlo method based algorithm established for a sample nanoelectronics device. We are assuming that at the nanoscale level like at the highest the thermal phenomena are important [...]

Smart Pressure Sensor on SOI optimized by Finite Element Analysis for Heatspreader Integration

Bercu B., Montès L., Morfouli P., INPG-MINATEC, FR

Finite element analysis is used to maximize the response of the piezoresistive pressure sensor into an integrated heatspreader, designed for high-power electronic device cooling. This study shows the possibility of obtaining small area piezoresistive pressure [...]

Programmable Three-Dimensional Microfluidic Fabrication by Direct-Write Assembly

Ghafar-Zadeh E., Therriault D., Sawan M., École Polytechnique de Montréal, CA

There are increasing needs for 3D microfluidic components such as microchannels, micromixers or micropumps for Laboratory-on-chip systems. To date, several efficient, but expensive and complex techniques such as Liga and micro-stereo-lithography [1] have been developed [...]
