Water adsorption on a sodium smectite clay surface: an ab initio study

John Christopher Plummer, Pascal Clausen

Using calculations based on density-functional theory, we explore the configurations that water molecules (2,3,4;6) assume on the surface a sodium 2:1 smectite clay with isomorphic substitutions both on octahedral and tetrahedral sheets. The hydrophilicity ...

Ion-implanted compliant and patternable electrodes for miniaturized dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Muhamed Niklaus

This article presents metal ion implantation as an alternative technique to fabricate compliant electrodes for small-size dielectric elastomer actuators. When reducing the size of these actuators to below 1 cm, the ability to pattern the electrodes is adde ...

Fluorine based plasma treatment of biocompatible silicone elastomer. Effect of temperature on etch rate and surface properties

Arnaud Bertsch, Cyrille Hibert

This paper describes F-based dry etching and resulting surface properties of biocompatible silicone elastomer. The etch rate of polysiloxane and surface morphology was found to be highly temperature dependent. An increase in temperature results in a signif ...

Metal ion implanted electrodes for dielectric elastomer actuators

Samuel Rosset

This thesis reports on the successful use of low-energy metal ion implantation to fabricate compliant electrodes for miniaturized dielectric elastomer actuators (DEAs, also known as artificial muscles). DEAs are elastomeric actuators capable of large defor ...

Selective removal of acetone and butan-1-ol from water with supported ionic liquid-polydimethylsiloxane membrane by pervaporation

Paul Joseph Dyson, Zhaofu Fei

The use of ionic liq.-polymer in supported ultrafiltration membrane in vacuum pervaporation has been verified. The ultrafiltration membranes were impregnated by two ionic liqs. (1-ethenyl-3-ethyl-imidazolium hexafluorophosphate and tetrapropylammonium tetr ...

3-D modulable PDMS-based microlens system

Luis Guillermo Villanueva Torrijo, Victor Javier Cadarso Busto

The design, simulation, fabrication and characterization of 3-D modulable micro-optical system based on poly-dimethilsiloxane (PDMS) are presented in this paper. This system consists on two uncoupled PDMS lenses with different diameter (2 and 10 mu m). Und ...

Interface interactions in hybrid organosilane-nitride films on polymer substrates

Yves Leterrier

Organic-inorganic hybrid coatings are becoming increasingly important due to their unique property combination [1, 2], including high optical transparency, improved scratch and abrasion resistance and excellent weathering, thanks to the synergism between t ...

Plasma silane concentration as a determining factor for the transition from amorphous to microcrystalline silicon in SiH4/H-2 discharges

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm

In this work, the microstructure transition from amorphous to microcrystalline silicon is defined in terms of the silane concentration in the plasma as opposed to the silane concentration in the input gas flow. In situ Fourier transform infrared absorption ...

A fast low-temperature micromolding process for hydrophilic microfluidic devices using UV-curable acrylated hyperbranched polymers

Yves Leterrier, Lars Schmidt

A novel UV-curable low-stress hyperbranched polymer (HBP) micromolding process is presented for the fast and low-temperature fabrication of hydrophilic microfluidic devices. Process, material and surface properties of the acrylated polyether HBP are also c ...

Influence of dehydration-rehydration process on rheological properties of liquid fruit foods

Paolo Perona

The effects of the dehydration-rehydration process on the recovering of the original rheological characteristics of the re-hydrating solution were studied. Four different fruit fluid products were investigated: apricot, banana purees, non-pureed citrus fru ...
