Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intra- cellular level. While able to image tissue samples with up to 5nm isotropic resolution, image acquisition is prohibitively sl ...

Light-trapping textures were produced in hyperbranched polymer (HBP) silica nanocomposites using a UV-nanoimprint lithography (UVNIL) replication method, either in batch or roll-to-roll processes. The hardness of the HBP was found to increase by a factor o ...

For biologists studying the morphology of cells, Electron Microscopy (EM) is the method of choice with its {\it nm} resolution, across increasingly larger volumes. However, the time necessary to acquire such image series is long and often limits the amount ...

Modélisation physique et analyse numérique de la propagation d'une masse granulaire

Claire Sauthier

Rock avalanches are processes involving a huge amount of mobilised material, larger than 106 m3, and their propagation is characterised by a very high energy, such that no active mitigation measure is capable of protecting human lives and properties potent ...

Self-Assembled Molecular Rafts at Liquid|Liquid Interfaces for Four-Electron Oxygen Reduction

Hubert Girault, Jiri Vanicek, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Tomas Zimmermann

The self-assembly of the oppositely charged watersoluble porphyrins, cobalt tetramethylpyridinium porphyrin (CoTMPyP4+) and cobalt tetrasulphonatophenyl porphyrin (CoTPPS4−), at the interface with an organic solvent to form molecular “rafts”, provides an e ...

Electron-beam induced photoresist shrinkage influence on 2D profiles

Vasiliki Tileli

For many years, lithographic resolution has been the main obstacle in keeping the pace of transistor densification to meet Moore's Law. For the 32 nm node and beyond, new lithography techniques will be used, including immersion ArF (iArF) lithography and e ...

Catalyst preparation with ball milling for catalytic synthesis of coiled carbon nanotubes

László Forró, Klara Hernadi

The aim of our experiments was the production of helically coiled carbon nanotubes selectively. The influence of catalytic particles prepared by ball milling (dry and wet method) was investigated on the growth. of coiled carbon nanotubes under conditions. ...

Consolidation of net-shape random fiber thermoplastic composite preforms

Véronique Michaud, Patrick Blanchard, Martyn Douglas Wakeman, Simon Jespersen

A novel thermoplastic composite preforming process has been developed. This thermoplastic programmable powdered preforming process (TP-P4) uses commingled glass and polypropylene yarns, which are chopped to a desired length and deposited onto a vacuum scre ...

Fabrication and Characterization of 1-D diffusing elements

Hans Peter Herzig, Roland Andreas Bitterli, Toralf Scharf, Myun Sik Kim

Certain high power laser applications require thin homogeneous laser lines. In this paper we describe the concept, fabrication and characterization of a 1-D diffuser that generates such a line. The device is based on an array of concave cylinder lenses wit ...

Local tuning of the optical response of two-dimensional photonic crystals

Romuald Houdré, Libero Zuppiroli, Rolando Ferrini, Laurent Balet

Local tuning of the optical response of GaAs-based two dimensional photonic crystals (PhCs) is reported. A selective polymer infiltration technique was developed. Scanning electron microscopy and optical measurements were used to characterize the filled Ph ...
