Experimental method to characterize the strain dependent permeability of tissue engineering scaffolds

Dominique Pioletti, Naser Nasrollahzadeh Mamaghani

Permeability is an overarching mechanical parameter encompassing the effects of porosity, pore size, and interconnectivity of porous structures. This parameter directly influences transport of soluble particles and indirectly regulates fluid pressure and v ...

Avoiding compositional drift during the RAFT copolymerization of N-(2-hydroxypropyl)methacrylamide and N-acryloxysuccinimide: towards uniform platforms for post-polymerization modification

Harm-Anton Klok, John Moraes, Ioana-Maria Simionca

Controlled radical polymerization techniques such as RAFT allow fine control over polymer molecular weight and architecture. These techniques, however, do not eliminate compositional drifts in copolymerizations, which are the consequence of differences in ...

Correlation between flocculation and adsorption of cationic polyacrylamides on precipitated calcium carbonate

Jutta Christine Wandrey, David Hunkeler, Hamideh Ahmadloo

The study of each stage of the flocculation process is essential to better understand and predict flocculation mechanisms. The adsorption of cationic polyacrylamide derivatives (C-PAM) onto precipitated calcium carbonate (PCC) has been investigated systema ...

Photo-polymerization, swelling and mechanical properties of cellulose fibre reinforced poly(ethylene glycol) hydrogels

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

The application of hydrogels as load-bearing biomedical components is often limited by their mechanical properties. Often an attempt to improve a hydrogel's stiffness is accompanied by a loss of toughness and swelling properties. In this work, we show that ...

Controlling conjugated polymer morphology and charge carrier transport with a flexible-linker approach

Kevin Sivula, Andrea Gasperini, Sébastien Jacky Daniel Bivaud

The Stille-coupling polymerization of a short conjugated polymer with an aliphatic linker was used to demonstrate a prototype in a new class of polymer semiconductors wherein the conjugation segment length and the length of the entire chain can be independ ...

An experimental design methodology to evaluate the importance of different parameters on flocculation by polyelectrolytes

Jutta Christine Wandrey, David Hunkeler, Hamideh Ahmadloo

Aggregation of particles is fundamental for improving the performance of many solid/liquid processes. Aggregation can be induced by different means, and one of the most common is based on the addition of polymeric additives, namely polyelectrolytes. In thi ...
