ResIn: A Combination of Result Caching and Index Pruning for High-performance Web Search Engines

Results caching is an efficient technique for reducing the query processing load, hence it is commonly used in real search engines. This technique, however, bounds the maximum hit rate due to the large fraction of singleton queries, which is an important l ...

An Epoxy Photoresist Modified by Luminescent Nanocrystals for the Fabrication of 3D High-Aspect-Ratio Microstructures

Jürgen Brugger, Vahid Fakhfouri

An epoxy-based negative-tone photoresist, which is known as a suitable material for high-aspect-ratio surface micromachining, is functionalized with red-light-emitting CdSe@ZnS nanocrystals (NCs). The proper selection of a common solvent for the NCs and th ...

Introduction of hydroxyl- or keto- functionalities into the side chain of azetidin-2-ones via allylic bromide rearrangement, followed by supported reagent substitution

Fides Benfatti

This paper reports the allylic bromide rearrangement of 3-bromo-3-alkenyl-azetidin-2-ones, induced by m-chloroperbenzoic acid, N-bromosuccinimide or benzoylperoxide as radical initiators. The substitution of bromide by resin supported acids, followed by hy ...

Microfabrication of ceramic components by microstereolithography

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technique that allows the manufacture of small and complex three-dimensional (3D) components in plastic material. Many of the components produced by this technique are too small and too complex to be replicated by molding and, c ...

Ceramic microcomponents by microstereolithography

Philippe Renaud, Heinrich Hofmann, Arnaud Bertsch, Sébastien Jiguet

This paper describes new polymer/ceramic photosensitive resins that can be used in the microstereolithography process for manufacturing complex 3D components in composite material. These new resins contain high loads (up to 80 wt.%) of alumina nanoparticle ...

Microfabrication d'objets composites fonctionnels en 3D et à haut facteur de forme, par procédés UV-LIGA et microstéréolithographie

Sébastien Jiguet

The present thesis deals with new composite photoresists for the UV-LIGA and microstereolithography microfabrication processes. The aim is to build functional 3D objects, with high aspect ratio. Two projects have been investigated in parallel for each micr ...

Microstereolithography: a review

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technology at the interface of the microengineering and rapid prototyping domains. It has evolved from the stereolithography technique, and is also based on a light-induced layer- stacking manufacturing, As the resolution of the ...

Microstereolithography: Concepts and applications

Philippe Renaud, Arnaud Bertsch

Microstereolithography is a new microfabrication process that evolved from the rapid prototyping industry. The first developments in this technology started in 1993 and different research teams around the world have developed microstereolithography machine ...

Microstereolithography: a new process to build complex 3D objects

Philippe Renaud, Arnaud Bertsch

In this paper, a new microstereolithography apparatus is described. It is an integral process in which a complete layer can be made in one exposure only, in contrast to vector-by-vector processes which are based on the vectorial tracing of each layer. As f ...

3D microfabrication by combining microstereolithography and thick resist UV lithography

Philippe Renaud, Arnaud Bertsch

A new approach for the realization of true 3D polymer structures is presented in this paper. It consists in adding, in a post-processing microstereolithography step, 3D polymer microstructures on top of a micropart patterned by means of planar processes su ...
