Screen-printed polymer-based microfluidic and micromechanical devices based on evaporable compounds

Peter Ryser, Thomas Maeder, Caroline Jacq, Yannick Sébastien Fournier, Nathalie Sophie Adeline Serra

We investigate in this work the fabrication of polymer fluidic and mechanical devices based on evaporable compounds as sacrificial layers using the screen-printing process. The combination of thermosetting polymer resins with evaporable compounds as sacrif ...

High-performance, nano-structured LiMnPO4 synthesized via a polyol method

Michael Graetzel, Nam Hee Kwon, Gianluca Deghenghi

A novel polyol synthesis was adopted to synthesize nano-structured LiMnPO4. This route yields well-crystallized nanoparticles with platelet morphology that are only similar to 30 nm thick oriented in the b direction. The obtained material presented a good ...

Optimum thickness of joints made of pultruded GFRP adherends and polyurethane adhesive

Thomas Keller, Till Vallée

This paper presents results of experimental and numerical investigations on double-lap joints composed of pultruded GFRP profiles and polyurethane adhesive subjected to quasi-static axial tensile loading. The objective was to investigate the effect of the ...

Time-intensity transformation and internal stress in UV-curable hyperbranched acrylates

Yves Leterrier, Lars Schmidt

The photocuring of three different highly functional acrylates—Di-pentaerythritol penta/hexaacrylate (DPHA) and two hyperbranched molecules (HBP), one with a stiff polyester and one with a more flexible polyether structure—was investigated by means of phot ...

New efficient synthetic routes toward functionalised polyketides

Gérald Coste

RNA plays key roles in essential biological processes, such as protein synthesis, transcriptional regulation, splicing and retroviral replication. The structural diversity of RNA molecules and the lack of known RNA repair mechanisms make these biopolymers ...

Synthesis and evaluation of 2'-O-substituted oligoribonucleotide analogues with new properties

Luc Reymond

During a previous, exploratory project in our group, it was observed that duplexes formed by oligonucleotides modified with polar 2'-O-substituents were more tolerant towards the addition of 1,2-dimethoxyethane (DME) than RNA and DNA duplexes [1]. Inspired ...

Low-Profile mechanisms in a PVAc/polyester blend

Véronique Michaud, Xavier Bulliard

The different steps associated with the curing of a PVAc/polyester blend are identified and correlated to the mechanism of shrinkage control in the presence of a low-profile additive (LPA). Poly(vinyl acetate) (PVAc) is used as a LPA and is shown to induce ...

Design of hybrid bridge girders with adhesively bonded and compositely acting FRP deck

Thomas Keller, Herbert Gürtler

Analytical prediction methods for axial stresses and deflections at the serviceability limit state and for ultimate failure loads are proposed for hybrid bridge girders consisting of FRP bridge decks adhesively bonded to steel girders. The methods allow fo ...

Silyl methallylsulfinates: efficient and powerful agents for the chemoselective silylation of alcohols, polyols, phenols and carboxylic acids

Pierre Vogel, Loay Awad, Cotinica Craita, Xiaogen Huang

Alcohols, phenols and carboxylic acids are silylated with very good yields in the presence of silyl methallylsulfinates under non- basic conditions and with the formation of volatile co-products. ...
