Minimally Invasive Photopolymerization In Intervertebral Disc Tissue Cavities

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

Photopolymerized hydrogels are commonly used for a broad range of biomedical applications. As long as the polymer volume is accessible, gels can easily be hardened using light illumination. However, in clinics, especially for minimally invasive surgery, it ...

Optimisation en Temps Réel: Optimiser les Performances des Procédés Chimiques malgré l’Incertitude et les Erreurs de Modélisation

Grégory François

This document summarizes the author’s research activities since 1999. They mainly focus on the modelling, the control and the optimization of processes and contributed to the development of real-time optimization methods (RTO), that is, process optimizatio ...

Multi-Scale Modeling Of Photopolymerization For Medical Hydrogel-Implant Design

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

We report on the modeling of a photopolymerizable hydrogel and its application as a replacement of the interior of the intervertebral disc (so called Nucleus Pulposus). The hydrogel is initially injected in its liquid form and then photopolymerized via a s ...

Solution viscosity and flocculation characteristics of linear polymeric flocculants in various media

Jutta Christine Wandrey, David Hunkeler

Rheological characteristics of linear copolymers of acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride (Q9), differing in molar mass and chemical composition, have been studied in distilled water (DW) and industrial water (IW) obtained from a ...

Synthesis of Pyridyl Disulfide-Functionalized Nanoparticles for Conjugating Thiol-Containing Small Molecules, Peptides, and Proteins

Jeffrey Alan Hubbell, Conlin O'Neil, Urara Hasegawa

Previously we reported emulsion polymerization of propylene sulfide with Pluronic F127 as an emulsifier, yielding nanoparticles (NPs) in the 25 nm size range. Immunologically functional NPs were prepared by adding an antigen Pluronic conjugate to the polym ...

Surface modification of PES virus filtration membrane

Claire Roulin

Virus filtration by size exclusion is a robust means of eliminating viruses in blood or pharma products. Porous polymer membranes with a narrow size distribution are used to allow passage of the protein product but retain viruses. The chosen polymer must r ...

Synthesis and characterization of novel polyelectrolytes based on double-charged cationic monomers

Ricardo Losada Mateo

Bis-1,3(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and bis-1,3(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A), two new double-charged monomers, were the subject of the research reported in this thesis. These monomers provi ...

We present a novel technological approach for the in situ realization of a micron-thin poly-acrylamide membrane in the center of a microfluidic channel. The membrane is formed by interfacial polymerization of an inner stream of monomer solution in between ...

The radical polymerization of bis-1,3(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride revealed non-ideality with 0.59 and 4.4 for the reaction orders of the initiator and monomer concentration, respectively. Further, autoacceleration was observed ...
