UV-nano-imprint lithography technique for the replication of back reflectors for n-i-p thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Karin Söderström

Texturing of interfaces in thin film silicon solar cells is essential to enhance the produced photocurrent and thus the efficiencies.AUVnano-imprint-lithography (UV-NIL) replication processwas developed to prepare substrates with textures that are suitable ...

Enhanced long-term microcircuit plasticity in the valproic Acid animal model of autism

Henry Markram, Kamila Markram, Tania Rinaldi, Jean-Vincent Le Bé, Imad Riachi, Guilherme Silva

A single intra-peritoneal injection of valproic acid (VPA) on embryonic day (ED) 11.5 to pregnant rats has been shown to produce severe autistic-like symptoms in the offspring. Previous studies showed that the microcircuitry is hyperreactive due to hyperco ...

The evaluation of colorimetric films for the detection of low concentrations of gaseous ammonia in a waveguide configuration is presented. They were composed of a pH indicator selective to NH3 embedded in a polymeric matrix and deposited on an optical wave ...

We propose a microfabrication technology for a flexible temperature sensor with a 100x100 mu m(2) sensing area and a probe length of 7 cm. We use a biocompatible new high temperature-resistant polyimide (U-Vamish-S, Ube, Dosseldorf, Germany) to embed a thi ...

Ieee Service Center, 445 Hoes Lane, Po Box 1331, Piscataway, Nj 08855-1331 Usa2007

Formulating effective coatings for use in nano- and biotechnology poses considerable technical challenges(1). If they are to provide abrasion resistance, coatings must be hard and adhere well to the underlying substrate(2). High hardness, however, comes at ...

2007

We present a new meshless animation framework for elastic and plastic materials that fracture. Central to our method is a highly dynamic surface and volume sampling method that supports arbitrary crack initiation, propagation, and termination, while avoidi ...

2005

A process for making hollow composite structures or vessels which includes the steps of: A) heating a mixture of thermoplastic matrix and reinforcing fibres wrapped over a rigid or semi-rigid thermoplastic liner or bladder above the melting point of the th ...

Nanocomposites based on luminescent colloidal nanocrystals in polymers: new opportunities for micro and nano fabrication

Jürgen Brugger, Vahid Fakhfouri

In recent years a wide range of materials including metals, semiconductors and metal oxides have been synthesized with nanometer dimensions. In particular II–VI semiconductor nanocrystals (NCs) are receiving considerable attention for fundamental studies a ...

2005

We present a method for modeling and animating a wide spectrum of volumetric objects, with material properties anywhere in the range from stiff elastic to highly plastic. Both the volume and the surface representation are point based, which allows arbitrar ...
