Order Development in Polymer-Clay Nanocomposites: from Aqueous Gels to Multilayered Films

Stefanescu C., Stefanescu E.A., Stefanescu C., Stefanescu E.A., Daly W.H., Negulescu I.I., Virginia Commonwealth University, US

When passing a material through a semihyperbolic convergent die in an elongational rheometer, high degrees of order are induced in the material, and the entropy changes, indicative of orientation, can be calculated. The aim of [...]

Proposal of Porous Chromium Film Fabrication Method for an IR Absorber

Kimura M., Hobara M., Tohoku Gakuin University, JP

Novel fabrication method of porous chromium (Cr) film for an infrared (IR) absorber is proposed, and total absorption factor above 93% at about 10 micron m of the IR wavelength, which is corresponding to the [...]

Multiscale Treatment of Thin-Film Lubrication

Wu Z-B, Diestler D.J., Zeng X.C., Chinese Academy of Sciences, CN

A multiscale technique that combines an atomistic description of the interfacial (near) region with a coarse-grained (continuum) description of the far regions of the solid substrates is proposed. The new hybrid technique, which represents an [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

Topics in Finite-Element Modeling of Piezoelectric MEMS Devices

von Preissig F.J., Kim E.S., University of Hawaii at Manoa, US

Techniques for modeling thin-piezoelectric MEMS devices using existing finite-element packages are examined. The emphasis is on non-resonant sensors and actuators, but most results are applicable to resonant devices and large structures as well. Characteristic features [...]
