Instability and Dynamics of EHD Flow with Unipolar and Bipolar Charge Injection in an Annulus

Fernandes D.V., Suh Y.K., Dong-A University, KR

Instability of steady-state conduction of a fluid in an annulus between two concentric circular cylinders subjected to charge injection either from the inner or outer and from both cylinder electrodes is considered. The results given [...]

Hydrophobic silicone elastomer chamber for recording trajectories of motile sperms without adsorption

Matsuura K., Funahashi H., Okayama University, JP

Sperm motility analysis is a representative method for evaluation of male fertility, since motility correlates with viability. The conventional method, commonly referred to as Computer-Assisted Sperm Analysis (CASA), to records motility and linear velocity (LV) [...]

Microfluidic manipulation of Caenorhabditis elegans using acoustic radiation forces

Yu G., Chen X., Xu J., Washington State University, US

The ability to precisely trap, transport and manipulate micrometer-sized objects is very important in microfluidic applications. Caenorhabditis elegans (C. elegans) is one of the most commonly used animals in biological and medical research due to [...]

Microfluidic Control of Adipose-Derived Stem Cell Growth and Positioning

Wadhawan N., Kalkat H., Ma X., Gajjeraman S., Nandagopal S., Hao N., Deng J., Xiang B., Zhang M., Tian G., Lin F., University of Manitoba, CA

Microfluidic devices provide powerful new tools for quantitative stem cell research owing to its advantages in cellular microenvironmental control and experiment throughput over conventional methods. Particularly, microfluidics is playing a growing role in studying stem [...]

Conductive Polymer Microelectrodes for on-chip measurement of transmitter release from living cells

Tylsgaard Larsen S., Matteucci M., Taboryski R., Technical University of Denmark, DK

In this work we present an all-polymer chip for measuring exocytotic release from neuronal cells using electrochemical sensing at a conductive polymer microelectrode. This chip combines several novel aspects, such as the use of conductive [...]

New microfluidic chip for the production of spherical gelled capsule for cell encapsulation

Dalle P., Morales S., Berthier J., Benhamou P-Y., Bellemin Comte A., Boizot F., Costa G., Rivera F., CEA-LETI, FR

Implantation of Langerhans islet in alginate shell is an alternative for the treatment of diabetes type 1. Finding an adapted process for cell encapsulation is a challenge. The process must product spherical and monodisperse capsules [...]

Numerical Simulation of the Solidification of Water-Based Nanofluid

El Hasadi Y.M.F., Khodadadi J.M., Auburn University, US

Nanofluids are colloidal suspensions which they consist particles in the size range of 100-1 nm. In the recent years nanofluids kept the attention of the scientific community due to their improved thermal physical properties compared [...]

Novel Chemistry and Dispersive Techniques for Diverse Applications

Hladik M., Brewer Science, US

Carbon nanotubes (CNTs) do not disperse very easily in organic media or at low viscosities. Thus, to produce a nanomaterial coating that can be applied by various methods, such as screen printing or ink-jet printing, [...]

Prediction of Thermal Conductivity of Liquid Methane/Ethane-Cu Nanofluids via Molecular Dynamics Simulations

Babaei H., Khodadadi J.M., Auburn University, US

The improvement of thermal conductivity by suspending nanoparticles in two hydrocarbon-based nanofluids is investigated by means of molecular dynamics simulations. Base fluids are methane and ethane and nanoparticles are pure copper. Two temperatures for which [...]
