Analytical investigation of nanofluids dispersion stability

Farzaneh H., Behzadmehr A., Samimi A., University of Sistan and Baluchestan, IR

Experimental and numerical investigations on nanofluids flows at different geometrical configurations and different thermo-fluid conditions show a significant enhancement on the convective heat transfer while the pumping power cost remains reasonable. However, many problems such [...]

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 [...]

Fabrication of Magnetic Poly (ethylene glycol) Hydrogels Blocks Using Microfluidic System for Cell Patterning Techniques

Chang H.-Y., Fu C.-Y., Lin C.Y., Wang T.-P., National Tsing Hua University, TW

In this study, we developed a novel technique called magnetic hydrogel-based cell patterning (MHCP) to easily achieve heterotypic cell patterning in both of multi-well plate-based methods and microfluidic system. We also demonstrated that the material [...]

Self-alignment of Silicon Chips on Wafers: the Effect of Spreading and Wetting

Berthier J., Brakke K., Sanchez L., Di Cioccio L., CEA-LETI, FR

3D integration appears as the key to advanced microelectronic systems. While robotic methods experience difficulties to accommodate fabrication speed and alignment accuracy, self-assembly methods are promising due to their parallel aspect, which overcomes the main [...]

Microchannel for IOP Relief and Glaucoma Treatment

Barth D., Heureaux J., Pilapil B., Ponce de Leon P., Zhao K., Stevens Institute of Technology, US

An implantable biomedical device intended for glaucoma treatment was designed, modeled, fabricated, and tested. Glaucoma is a degenerative eye disease that is normally characterized by high Intraocular Pressure (IOP) and causes progressive vision loss. According [...]

System for Measuring Drop Volume and Consistency in Lab-on-Chip Applications

Kipman Y., Mehta P., ImageXpert Inc., US

A machine vision based system has been developed for measuring in-channel characteristics of droplets for lab-on-chip microfluidic applications. The small, fully integrated system can be used in R&D and in production and combines a high-powered [...]

Array-Nozzle EHD Print Head and its Drop-on-Demand Experimentation

Son S., Lee S., Lee W.H., Kim Y.J., An K., Choi J., Sin J., Lee S., Lee W.H., Wijesundara M., Stephanou H.E., Sungkyunkwan University, KR

EHD (electrohydrodynamics) printing has recently attracted attention for micro/nano size pattern devices due to it can make very small droplet than nozzle diameter and possibility of the use of various ink such as including metal, [...]

High efficiency E. coli concentration via dynamic light-induced optoelectro-osmosis flow

Yang S.M., National Chiao Tung University, TW

We demonstrate a dynamic light-induced optoelectroosmosis flow design for E. coli concentration on an organic photoconductive material based biochip. Several traditional approaches of purification and enrichment for bacteria are to use magnetic beads coated with [...]

Hot spots active-cooling micro-channel heat sink device, using electro-osmotic flow

Al-Rjoub M.F., Roy A.K., Ganguli S., Banerjee R.K., University of Cincinnati, US

In this pilot study a micro-scale heat exchanger/ spreader was designed and tested. This device is dedicated for the thermal management of microchip hot spots. The basic design consisted of an array of microchannels etched [...]

Red Blood Cell Deformation in Flows through a PDMS Hyperbolic Microchannel

Yaginuma T., Oliveira M.S.N., Lima R., Ishikawa T., Yamaguchi T., FEUP - Faculdade de Engenharia da Universidade do Porto, PT

Red blood cells (RBCs) are the major cellular component in blood and are highly deformable in their normal state. RBC deformability is important in the delivery of oxygen to the tissues and plays a major [...]
