Zeolite Membrane Microreactors for Fine Chemical Synthesis

Zhang X., Lai S.M., Lam K.F., Yeung K.L., Martin-Aranda R., Hong Kong University of Science and Technology, CN

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 [...]

Control of Particles Using Multi-Frequency DEP

Loire S., Zhang Y., Bottausci F., Mezic I., McDonald N., university of california, santa barbara, US

We present numerical simulations and experiments on dielectrophoretic (DEP) separation and trapping performed in a titanium-based microchannel linear electrode array. The device is designed to allow for effects driven by inhomogeneities in electric-field magnitude driven [...]

The Optimisation of a Resonant Gas Sensor by Using Nano-Tectured Surfaces

Docker P.T., Kinnell P.K., Ward M.C.L., University of Birmingham, UK

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 [...]

Y-nano X-micro Technologies: nanometric optical control

de Lima Monteiro D.W., Honorato F.P., Ferreira Jr A.I., Soloviev O., Vdovin G., Loktev M., Federal University of Minas Gerais, BR

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 [...]

Intelligent Sensors: Systems or Components?

White N., Southampton University, UK

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 [...]

Towards Nano Mechanical Sensors

Hierold C., ETH Zürich, CH

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 [...]

MEMS Reliability Assessment ProgramMicro-electromechanical Systems (MEMS) Reliability Assessment Program for Department of Defense Activities

Zunino III J.L., Skelton D., Mason R., U.S. Army Corrosion Office, US

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 [...]
