Photopolymerization device for minimally invasive implants: application to nucleus pulposus replacement

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

Photopolymerization is a common tool to harden materials initially in a liquid state. A surgeon can directly trigger the solidification of a dental implant or a bone or tissue filler. Traditionally, photopolymerization has been used mainly in dentistry. Ov ...

Mesoscale Characterization of Supramolecular Transient Networks Using SAXS and Rheology

Maartje Martina Cornelia Bastings

Hydrogels and, in particular, supramolecular hydrogels show promising properties for application in regenerative medicine because of their ability to adapt to the natural environment these materials are brought into. However, only few studies focus on the ...

Composite hydrogels

Dominique Pioletti, Pierre-Etienne Bourban, Arne Christian Vogel

The present invention relates to reinforced composite hydrogel based on a polymer blend and comprising a network of fibres, said polymer blend comprising UV sensitive molecules. It also relates to a process for preparing the reinforced composite hydrogel a ...

Contribution to the Production and Characterization of W-Y, W-Y2O3 and W-TiC Materials for Fusion Reactors

Lyubomira Veleva

This PhD Thesis work was aimed at investigating the potentiality of tungsten-base materials as structural materials for the future thermonuclear fusion reactors in attempting to develop reduced activation tungsten-base materials with high strength and suff ...

Poroviscoelastic Characterization of Particle-Reinforced Gelatin Gels using Indentation and Homogenization

Matteo Galli, Joël Cugnoni, Elvis Fornasiere

Hydrogels are promising materials for bioengineering applications, and are good model materials for the study of hydrated biological tissues. As these materials often have a structural function, the measurement of their mechanical properties is of fundamen ...

High doses of sodium fluoride in bones lead to severe softening, by weakening interfacial properties between the inorg. minerals and the org. components, while leaving mineralization unchanged. This leads to redn. of microdamage and assocd. stress-whitenin ...

In finite element simulations dedicated to the modelling of microstructure evolution, the mesh has to be fine enough to: (i) accurately describe the geometry of the constituents; (ii) capture local strain gradients stemming from the heterogeneity in materi ...

Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
