Long-range adsorbate interactions mediated by a two-dimensional electron gas

We report on long-range interactions between adsorbates on metal surfaces with a surface state. A comparison of three adsorbate/substrate systems [Cu/Cu(111), Co/Cu(111), and Co/Ag(111)] suggests the general existence of such interactions and shows up comm ...

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 ...

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 ...

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 ...

Kinetic Arrest Originating in Competition Between Attractive Interaction and Packing Force

Giuseppe Foffi, Francesco Sciortino

We discuss the situation where attractive and repulsive portions of the interparticle potential both contribute significantly to glass formation. We introduce the square-well potential as prototypical model for this situation, and reject the Baxter model a ...

Determination of the rheological properties of thermoplastic composites for compression flow molding

Paul Sunderland

The influence of the fiber mat structure and the matrix rheology on the squeeze flow behavior of thermoplastic composites for compression flow molding has been investigated. An analytical model for isothermal squeeze flow has been developed and experimenta ...

Size Dependence of the Surface Plasmon Enhanced Second Harmonic Response of Gold Colloids: Towards a New Calibration Methods

Hubert Girault, Pierre-François Marie Brevet

Hyper Rayleigh scattering in solution is used for the determination of the first order hyperpolarizability b(colloid) of gold colloids in the size range 5–22 nm; these hyperpolarizabilities are found to range from 0.60 × 10–25 esu for 5 nm diameter colloid ...

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 ...

Growth, microstructure and sintering behavior of nanosized silicon powders

Christoph Hollenstein, Heinrich Hofmann

The growth and properties of nanosized silicon particles produced by gas-phase reaction in a low-pressure silane plasma has been studied. In situ ion-mass spectroscopy and Mie scattering measurements were used to monitor the formation of powders. High reso ...
