Vertical ordering of rods under vertical vibration

Thomas Liebling, Lionel Pournin, Marco Ramaioli

Granular media composed of elongated particles rearrange and order vertically upon vertical vibration. We perform pseudo-two-dimensional discrete element model simulations and show that this phenomenon takes place also with no help from vertical walls. We ...

Second harmonic generation response by gold nanoparticles at the polarized water/2-octanone interface: from dispersed to aggregated particles

Hubert Girault, Pierre-François Marie Brevet

Gold nanoparticles with a diameter of approximately 20 nm have been observed at the polarized water/2-octanone interface by the nonlinear optical technique of second harmonic generation. Electric field induced adsorption of the gold particles at this liqui ...

Phases of granular segregation in a binary mixture

Pedro Miguel Nunes Pereira de Almeida Reis

We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with the surface of a vibrating horizontal tray. Three distinct phases of the mix ...

Cargese lectures on extra-dimensions

Riccardo Rattazzi

I give a pedagogical introduction to the concepts and the tools that are necessary to study particle physics models in higher dimensions. I then give a more detailed presentation of warped compactifications and discuss their possible relevance to the hiera ...

Analyzing the scattering properties of coupled metallic nanoparticles

Hans Peter Herzig

We apply the boundary element method to the analysis of the plasmon response of systems that consist of coupled metallic nanoscatterers. For systems made of two or more objects, the response depends strongly on the individual particle behavior as well as o ...

Gases, liquids and crystals in granular segregation

Pedro Miguel Nunes Pereira de Almeida Reis

We report the results of an experimental investigation of segregation in a binary mixture of dry particles subjected to horizontal oscillatory excitation. The thin layer of particles was driven by the stick-slip frictional interaction with the surface of a ...

Homogenization method for transport of DNA particles in heterogeneous arrays

Assyr Abdulle

In this paper we study the large scale transport of the DNA particles through a heterogeneous micro array in the framework of homogenization theory. We derive the macro scale particle transport equation and show that for transport of particles in a diverge ...

The effects of calcium phosphate cement particles on osteoblast functions

Dominique Pioletti, Pascale Van Landuyt

Calcium phosphate cements (CPC) are increasingly used in the orthopedic field. This kind of cement has potential applications in bone defect replacements, osteosynthetic screw reinforcements or drug delivery. In vivo studies have demonstrated a good osteoi ...

Inverse grading in granular flow

The current work concerns with the parametrical dependencies of inverse grading in granular flows from material properties of individual particles involved in the flow. The investigations were initiated and motivated by the search for an explanation of the ...

The physics and chemistry of dusty plasmas

Christoph Hollenstein

An overview of the most recent experimental and modelling efforts on powder formation in reactive plasmas is given. The physics and chemistry of these dusty plasmas and their fundamental mechanisms leading to the production of nanometre-sized particles and ...
