Confirmation of anomalous dynamical arrest in attractive colloids: A molecular dynamics study

Previous theoretical simulation and experimental studies have indicated that particles with a short-ranged attraction exhibit a range of dynamical arrest phenomena. These include very pronounced reentrance in the dynamical arrest curve, a logarithmic singu ...

An Integrated Fritless Colum for On-Chip Capillary Electrochromatography with Conventional Stationary Phases

Nico de Rooij

A new polymer device for use with conventional particulate stationary phases for on-chip, fritless, capillary electrochromatography (CEC) has been realized. The structure includes an injector and a tapered column in which the particles of the stationary ph ...

Electroosmotic Flow in Composite Microchannels and Implications in Microcapillary Electrophoresis Systems

Hubert Girault, Patrik Willi Hoffmann, François Bianchi, Frank Rüdiger Wagner

The electroosmotic flow in laminated excimer laser-ablated microchannels has been studied as a function of the depth of the rectangular channels, and particular emphasis has been given to the difference in the ζ-potentials between the lamination layer and ...

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 ...

The morphology of hyperbranched polymer compatibilized polypropylene/polyamide 6 blends

The influence of hyperbranched polymer grafted polypropylene (PP-HBP) on the morphology of polypropylene (PP)/polyamide 6 (PA6) blends has been investigated. The final morphology was strongly influenced by the PP-HBP compatibilizer concentration. At low co ...

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 ...

Infiltration processing of fibre reinforced composites: governing phenomena

Andreas Mortensen, Véronique Michaud

All three classes of fibre reinforced composite materials (polymer, metal and ceramic matrix) may be produced by flow of liquid matrix into the open spaces left within pores of a fibre preform. Even though several specific issues arise from the nature of e ...

Scanning excimer laser ablation of poly(ethylene terephthalate) (PET) and its application to rapid prototyping of channels for microfluidics

Frank Rüdiger Wagner

Excimer Laser Ablation is a micro-machining method which has undergone an important breakthrough in the last twenty years. In contrast with most literature studies, dealing with Static Ablation, this PhD work focuses on the study of Scanning Ablation of po ...

Self-assembly and steric stabilization at heterogeneous, biological surfaces using adsorbing block copolymers

Jeffrey Alan Hubbell

BACKGROUND: We present the synthesis, characterization and initial structure-function analysis of a new class of bioactive agent that allows the application of techniques from colloid science to biological surfaces. Stable colloidal suspensions can be gene ...

Particle agglomeration study in rf silane plasmas: In situ study by polarization-sensitive laser light scattering

Christoph Hollenstein, Alan Howling

To determine self-consistently the time evolution of particle size and their number density in situ multi-angle polarization-sensitive laser light scattering was used. Cross-polarization intensities (incident and scattered light intensities with opposite p ...
