Simulating fully three-dimensional pressurized fracture propagation

Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy

We report the progress on a new computational technique for fully three-dimensional simulation of propagation of hydraulic fractures in the vicinity of a wellbore. One of the components of this technique is the boundary element code for modeling the elasti ...

Selective Trapping of DNA Using Glass Microcapillaries

Nadanai Laohakunakorn

We show experimentally that an inexpensive glass microcapillary can accumulate lambda-phage DNA at its tip and deliver the DNA into the capillary using a combination of electro-osmotic flow, pressure-driven flow, and electrophoresis. We develop an efficien ...

Metal-Coated SU-8 Structures for High-Density 3-D Microelectrode Arrays

Carlotta Guiducci, Samuel Kilchenmann, Pietro Maoddi, Enrica Rollo

Electric fields can be effectively used to sense, manipulate, and move particles in lab-on-a-chip devices. Nevertheless, the throughput of such devices is a critical issue, which can be effectively improved by increasing the height of the microchannels. Fo ...

Institute of Electrical and Electronics Engineers2016

The objective of this project is the fabrication of hollow piezoelectric micro electric mechanical systems (PZE-MEMS) arrays with suspended micro-channels integrated with a microfluidic network. The ultimate goal is to demonstrate the feasibility of charac ...

Microfluidic chip for monitoring Ca2+ transport through a confluent layer of intestinal cells

Martinus Gijs, Paolo Silacci, Hüseyin Cumhur Tekin, Josias Basil Wacker, Christine Ruffert, Guy Vergères

The absorption of dietary calcium through the intestinal barrier is essential for maintaining health in general and especially of the bone system. We propose a microfluidic model that studies free calcium (Ca2+) transport through a confluent monolayer of C ...

Zipping dielectric elastomer actuators: characterization, design and modeling

Herbert Shea, Samuel Rosset, Luc Maffli

We report on miniature dielectric elastomer actuators (DEAs) operating in zipping mode with an analytical model that predicts their behavior. Electrostatic zipping is a well-known mechanism in silicon MEMS to obtain large deformations and forces at lower v ...

Drying techniques for microfluidic and other systems

Esther Amstad

The present invention generally relates to microfluidics, and to spray drying and other drying techniques. Various embodiments of the invention are generally directed to systems and methods for drying fluids contained within a channel such as a microfluidi ...

2013

We present a novel image-based method to measure the on-chip microfluidic pressure and flow rate simultaneously by using the integrated optofluidic membrane interferometers (OMIs). The device was constructed with two layers of structured polydimethylsiloxa ...
