Dynamical arrest in dense short-ranged attractive colloids

We study thermodynamic and dynamic properties of model colloidal systems interacting with a hard core repulsion and a short-range attraction, and provide an overall picture of their phase diagrams which shows a very rich phenomenology. We focus on the slow ...

Wetting, interfacial interactions and sticking in glass/steel systems

Andreas Mortensen

Wetting and sticking of soda-lime glass on two types of stainless steel as well as on platinum and vitreous carbon substrates are studied in a neutral gas atmosphere between 860 and 1200degreesC. Wetting is measured by the "transferred drop" version of the ...

Low-temperature thick-film dielectrics stabilised by reaction with a nanocrystalline powder

Peter Ryser, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

In this work, a low-temperature thick-film dielectric consisting of a high-lead low-temperature glass with a reactive nanoscale filler is characterised to enable deposition of thick-film electronics onto substrates such as glass and metals (steel, aluminiu ...

Competition between crystallization and glassification for particles with short-ranged attraction. Possible applications to protein crystallization

Giuseppe Foffi, Francesco Sciortino

We discuss the phase behaviour of spherical hard-core particles, with an attractive potential, as described by a hard-core Yukawa model. The ratio of the range of the attraction to the diameter of the particles is an important control parameter of the prob ...

Mode-coupling theory of colloids with short-range attractions

Giuseppe Foffi, Francesco Sciortino

Within the framework of the mode-coupling theory of super-cooled liquids, we investigate new phenomena in colloidal systems on approach to their glass transitions. When the inter-particle potential contains an attractive part, besides the usual repulsive h ...

Higher-order glass-transition singularities in colloidal systems attractive

Giuseppe Foffi, Francesco Sciortino, Martin Fuchs

The transition from a liquid to a glass in colloidal suspensions of particles interacting through a hard core plus an attractive square-well potential is studied within the rnode-coupling-theory framework. When the width of the attractive potential is much ...

Mechanical properties of a model of attractive colloidal solutions

Giuseppe Foffi, Francesco Sciortino

We review the nature of glass transitions and the glasses arising from a square-well potential with a narrow and deep well. Our discussion is based on the mode coupling theory (MCT), and the predictions of glasses that we make refer to the â€œidealâ€? glas ...

Development of novel low temperature bonding technologies for microchip chemical analysis applications

Martinus Gijs, Abdeljalil Sayah, Dominique Solignac

We introduce two new low temperature bonding technologies for the assembly of microstructured glass substrates for the realisation of microchannels for miniaturised chemical analysis applications. A first method consists of a proper cleaning of the two gla ...

Novel low temperature pressure-assisted bonding technology

Martinus Gijs, Abdeljalil Sayah, Dominique Solignac

We introduce a new low temperature bonding technology to assemble two microstructured glass substrates for the realization of microchannels for miniaturized chemical analysis applications. To realize the microchannels, we introduce, besides the well-known ...

Compression moulding of glass and polypropylene composites for optimised macro- and micro- mechanical properties. Part 4 : technology demonstrator - a door cassette structure

Martyn Douglas Wakeman

A systematic study of the effects of charge composition and process parameters is presented for a prototype automotive part (a door cassette) produced by compression moulding from glass fibre and polypropylene composites. This follows previous studies (Par ...
