We recently started a program at Argonne to exploit patterned, polarizable ferroelectric surfaces, such as lead zirconium titanate (PZT), as a means to create field-responsive inorganic-biomolecule interfaces to study and manipulate biomatter on surfaces. In [...]
We have developed and implemented a method which when given a three-dimensional object can infer from the object's topology the two-dimensional masks needed to produce that object with surface micromachining. The masks produced by this [...]

A recently developed RF-MEMS technology based on high resistivity Silicon substrate and suspended gold membrane is proposed for the design of a switching dual frequency LC-tank, for the implementation of a hybrid MEMS-CMOS dual-band voltage [...]
Paper describes the fabrication and testing of a micromachined electrical field-flow fractionation system, performing separations of various types of nanoparticles.
Using higher order sigma-delta modulator topologies, similar to the ones used for electronic A/D converters, and applying them to micromachined capacitive sensors is a promising approach to increase the performance of these sesnors. The paper [...]
As the U.S. Army transforms into a lighter, more lethal force, the technologies that support both legacy and emerging weapon systems must decrease in size while increasing in intelligence. Micro-electromechanical systems (MEMS) are one such [...]
This paper is about the impact of scaling on the system performance of mechanical inertia sensors and first activities towards nano mechanical sensors. Permanent cost pressure will result in continuous efforts to integrate more functions [...]
This paper reviews the field of intelligent (smart) sensor technology and describes some of the trends that have emerged over the last two decades. The functionality of intelligent sensors is discussed, together with an assessment [...]

Nanometric control of optical quality is relevant in many different fields, ranging from Ophthalmology to Lithography, where ordinary setups suffer from optical aberrations. Most common aberrations feature amplitudes in the nanometer range and are often [...]
This paper describes the potential for optimising a resonant gas sensor by using nano-textured surfaces. Initial modelling proved that a device with a nano-textured active layer could have its surface area increased by an order [...]

The performance of a membrane microreactor was tested and compared with that of microreactor, packed bed reactor (PBR) and packed bed membrane reactor (PBMR) for the Knoevenagel condensation reaction of benzaldehyde and ethyl cyanoacetate to [...]
The advance of MEMS based sensors and microfabrication techniques has facilitated innovative technologies such as so-called ‘atom chips’, where a cloud of ultra cold atoms in a Bose Einstein Condensate (BEC) is controlled and manipulated [...]
Electro-thermal polysilicon actuators are widely employed in optical MEMS applications. These actuators are typically designed for maximum deflection (unloaded) or force (loaded) output characteristics. The optimal design methodology of the actuator has been investigated previously [...]

This paper reports on modeling/simulation and design, MEMS-based fabrication of MHz ultrasonic nozzles, and their applications to micro- and nano-technologies. The ultrasonic nozzle is made of a piezoelectric drive section and a silicon-resonator consisting of [...]
This paper presents a mechanism of developing a novel out-of-plane micro electrostatic actuator capable of causing large out-of-plane deflection. The proposed actuation mechanism is using the attraction force between the charged bodies to bend the [...]
