Design of Optimized Microfluidic Devices for Viscoelastic Fluid Flow

Alves M.A., Universidade do Porto - Faculdade de Engenharia, PT

In this work we present a fully automated procedure for the design of microfluidic devices with optimal performance. The proposed approach combines an in-house finite-volume viscoelastic flow solver, an optimizer, and an automatic mesh generation [...]

Modeling Nanoscale Plasmon-assisted Bubble Nucleation and Applications

Furlani E.P., Swihart M.T., Litchinitser N., Delametter C.N., Carter M., University at Buffalo, US

Metallic nanoparticles exhibit a plasmon resonance at optical frequencies that enables efficient conversion of optical to thermal energy at the nanoscale. This photothermal coupling can be leveraged for various applications using femtosecond-pulsed laser illumination tuned [...]

Design, Simulation, and Prototyping of an Impulse Turbine for Biomedical Applications

Cabra H., University of South Florida, US

An impulse bio-turbine with circular inlet/outlet area is presented. The system was designed using a scaled impulse macro turbine model, which was modified in size and shape to facilitate transformative integration in implantable biomedical devices [...]

The Physics of Pressure Powered Micro-Flow Focusing Device for the Encapsulation of Live Cells

Berthier J., Dalle P., Rivera F., Renaudot R., Morales S., Benhamou P-Y., Caillat P., CEA-LETI, FR

Flow focusing devices (FFD) have emerged as a powerful tool for cell encapsulation and formation of micro-emulsions [1,2]. In the frame of live cell encapsulation, a micro-FFD using alginate solutions for the capsule and powered [...]

Capillary Electrophoresis in Nanofluidic Channels

Atzberger P.J., Gibou F., Pennathur S., university of california, santa barbara, US

Electrophoretic separation in nanofluidic channels exhibits significant differences with microfluidics. We discuss a theoretical / experimental collaboration investigating particle separation by electropohoresis in nanochannels. Recent experimental results in the laboratory of our collaborator Dr. Pennathur [...]

Simulating the Fast Transport of Water Through Carbon Nanotubes

Nicholls W.D., Borg M.K., Reese J.M., University of Strathclyde, UK

This paper presents our simulation results of pressure-driven water flow through a single (7,7) CNT 2.5nm in length as part of an investigation of the reasons for such high flow rates. A pressure gradient is [...]

Using nanofluids to enhance the operation of solar energy systems

Otanicar T., Loyola Marymount University, US

Nanofluids have garnered a lot of attention for their potential to modify thermal properties, particularly the thermal conductivity. While these modifications have been heavily investigated within the heat transfer and materials community, nanofluids additionally offer [...]
