Chaotic advection induced by a magnetic chain in a rotating magnetic field

Kang T.G., Hulsen M.A., Anderson P.D., den Toonder J.M.J, Meijer H.E.H., Eindhoven University of Technology, NL

We investigated chaotic advection induced by a magnetic chain suspended in a fluid in a rotating magnetic field. Our main focus is on the dynamics of the chain and the route to induce chaotic mixing, [...]

Novel piezo motor enables positive displacement microfluidic pump

Henderson D., New Scale Technologies, US

Microfluidic pumping mechanisms, such as membrane micro pumps, create a pulsed stream with generally low pressure, low flow and limited precision. We present a novel piezoelectric motor that is used to create a positive displacement [...]

Embeddable Low-Voltage Micropump using Electroosmosis of the Second Kind

Heldal T., Volden T., Auerswald J., Knapp H., IQ Micro Inc., CH

A low-voltage micropump with no moving parts and based on standard MEMS fabrication techniques has been developed. High pumping rate is achieved by using electroosmosis of the second kind (EO2). The pump has been characterized [...]

Nanodroplet Impact on Liquid Substrates via Molecular Dynamics

Lussier D., Kakalis N.M.P., Ventikos Y., University of Oxford, UK

In this paper, several aspects of the dynamic behaviour of liquid nanodroplets impacting on liquid substrates are investigated using molecular dynamics (MD) simulations. We consider liquid droplets of 5-10 nm in diameter, consisting of 7,000 [...]

Fabrication of 1D nanochannels with thin glass wafers for single molecule studies

Hoang H., Segers-Nolten I., Tas N., de Boer M., Subramaniam V., Elwenspoek M., Mesa+ Institute for Nanotechnology, NL

1D nanochannels are fabricated by direct bonding between the silicon wafer containing the nanochannels, microchannels, access holes and the blank thin glass of 170 µm thickness. The thin glass wafers are used as channel covers [...]

Multi-walled Carbon Nanotube Film as Strain Sensors for Structural Vibration Control

Li X., Levy C., Florida International University, US

We have employed pure multi-walled carbon nanotube (MWCNT) films as strain sensors for structural vibration control. The MWCNT films were prepared by solution/filtration method and were bonded directly onto aluminum specimens by nonconductive adhesives. Conventional [...]
