Magnetohydrodynamic Liquid Metal Jet Printing

Vader S., Vader Z., Vader S., Vader Z., Karampelas I.H., Furlani E.P., SUNY-Buffalo, US

We present a novel method for drop-on-demand (DOD) printing of molten metal droplets into 3D objects. This method involves the use of heating to pre-melt a solid metal structure (e.g. rod) to form a reservoir [...]

Fishbone Pattern Phenomena on a Non-Conductive Substrate in Electrohydrodynamic Discharging

Son S., Lee S., Choi J., Haque S., Sungkyunkwan University, KR

The intense electric field concentrated on the meniscus at a nozzle orifice is able to trigger the electro-hydrodynamic (EHD) discharging of tiny droplets or jets [1-2]. The electric field distribution along the pathway from the [...]

Fabrication of Active Digital Microfluidic Paper Chips with Inkjet-printed Patterned Electrodes and their Point-of Care Biomedical Application

Ko H., Lee J., Kim K., Kim Y., Kee Y., Kim K., Kim Y., Jung C-H, Choi J-H, Kwon O-S, Shin K., Sogang University, KR

Active, paper-based, microfluidic chips driven by electrowetting are fabricated by using inkjet printing and demonstrated for reagent transport and mixing. Instead of using the passive capillary force on the pulp to actuate a flow of [...]

Superhydrophobic 3D Printed Surfaces by Dip-Coating

Milionis A., Loth E., Bayer I.S., University of Virginia, US

Here we demonstrate a technique to fabricate three-dimensional superhydrophobic patterns. First a three-dimensional pattern was designed by 3D printing using acrylonitrile butadiene styrene (ABS) as printing material. A linear printing algorithm is followed for the [...]

Reliability Evaluation of Inkjet-Printed Silver Patterns for Application to Printed Circuit Board

Shin K.-Y., Kang H.S., Kang K.T., Kang H.S., Kang K.T., Hwang J.Y., Lee S-H., Kim J-M, Korea Institute of Industrial Technology, KR

Recently, several studies on the reliability of inkjet-printed patterns have been conducted to evaluate inkjet printing technology as a fabrication process for the printed circuit board industry. However, the methods and standards for evaluating the [...]

Simulation of desolvated self-assembly in a picoliter drop of colloidal solution by dissipative particle dynamics

Lebedev-Stepanov P., Photochemistry Center, RU

A method of dissipative particle dynamics of charged colloidal submicro- and nanoparticles in evaporating picoliter droplet of solution deposited on plane substrate is proposed for investigation of self-assembly and self-ordering of colloids during solute evaporation, [...]

A Simple and Robust Fabrication of Microwell Array by Pdms on a Glass Substrate for Cell-To-Cell Adhesion

Lee H., Row S., Xu L., Andreadis S.T., Oh K.W., SUNY at Buffalo, US

We describe a simple micro-fabrication method by using polydimethylsiloxane (PDMS) patterns on a glass substrate that enables simultaneous control of cell-to-cell adhesion. While the microwells used previously facilitated the cell-to-cell formation by PDMS stamping method, [...]

Pore wall charge patterning and spatial profiles of electrical conductivity in short nanopores

Tajparast M., Glavinovic M.I., McGill University, CA

Artificial nanopores are now used as filters, nanofluidic switches or biosensors. Given that their functioning often critically depends on pore conductivity it is important to determine what influences the pore conductivity and how far these [...]

Modeling of liquid pumping via microchannels

Berdenova B., Ainabayev A., Insepov Z., Hassanein A., Bralts V., Insepov Z., Purdue University, US

We present our finite element modeling and discuss the main principles of our water actuation technique for water transport in micron scale tubes. The effect of water flow actuation by application of surface acoustic waves [...]
