Superparamagnetic iron oxide nanoparticles (SPIONs): from synthesis to in vivo studies - A summary of the synthesis, characterization, in vitro and in vivo investigations of SPIONs with particular focus on surface and colloidal properties

In this work, we present a short summary of the synthesis and characterization of superparamagnetic iron oxide nanoparticles and their behavior in vitro and in vivo. Therefore, we have used various characterization techniques to deduce the physical particl ...

Low stress acrylated hyperbranched polymers

Lars Schmidt

The objective of this study was to investigate the behavior of highly functional acrylates, during isothermal ultraviolet (UV) curing. The materials included a pentafunctional acrylate and two acrylated hyperbranched polymers, one with a stiff polyester co ...

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 ...

Magnetic and electrostatic effects on the polymerization of water-soluble monomers

Ignacio Rintoul

Free radical polymerization is the most frequently used technique to produce synthetic polymers. They represent more than 25% of the total volume of materials made by the mankind. 3% thereof correspond to water soluble polymers with annual growth rates est ...

Microdeformation mechanisms in rubber toughened PMMA and PMMA-based copolymers

John Christopher Plummer, Laure Dupuits Lalande

The classical method of toughening polymethylmethacrylate (PMMA) is to incorporate composite rubber particles into the homopolymer matrix. This approach has been extended in the present work by (i) combining rubber toughening with chemical modification of ...

Reaction calorimetry in supercritical fluids

Sophie Fortini

This thesis is devoted to the study of the dispersion polymerization of methyl methacrylate in supercritical carbon dioxide (scCO2), using a poly(dimethylsiloxane) macromonomer (PDMS macromonomer) as stabilizer. Supercritical fluids (SCF) and SCF mixtures ...

High performance thick-film pressure sensors on steel

Peter Ryser, Sebastien Martinerie, Thomas Maeder, Caroline Jacq, Giancarlo Corradini

The aim of this work is to examine the possibility of high performance pressure sensors based on piezoresistive thick films deposited on steel membranes, which combine the performance advantage of thin-film sensors (high-strength steel substrates, assembly ...

Photorheology of Fast UV Curing Multifunctional Acrylates

Yves Leterrier, Jean-Marc Vesin, Lars Schmidt

The fast photopolymerization of different multifunctionalacrylates was analyzed by means of photorheology.The materials studied included a penta/hexaacrylatemonomer and two different acrylated hyperbranchedpolymers. The sensitivity of the commercial rheome ...

Adsorption of charged macromolecules on oppositely charged porous column materials

Jutta Christine Wandrey, Vesela Malinova

A family of cationic polyelectrolytes possessing defined chain lengths, narrow chain length distributions, uniform charge d., but substituents of different hydrophilicity at the quaternary ammonium group served as model compds. for adsorption studies. Thes ...

Novel Pulp Fibre Reinforced Thermoplastic Composites

Yves Leterrier

The reinforcement potential of pulp fibres is presently not fully explored in thermoplastic composites. One of the reasons is that currently used processing methods comprise several severe thermomechanical steps inducing premature degradation of the fibres ...
