Lafont, U.L. (author), Van Zeijl, H. (author), Van der Zwaag, S. (author)In this work, we investigate the formation of self-healing systems that are able to recover more than once more than one (mechanical or other physical) functionality. To this aim composites were created consisting of a polysulfide thermoset rubber matrix having intrinsic self-healing properties filled with thermally/electrically conductive...conference paper 2013

Lafont, U.L. (author), Van Zeijl, H.W. (author), Van der Zwaag, S. (author)While conventional self healing materials focus on the restoration of mechanical properties, newer generations of self healing materials focus on the restoration of other functional (i.e. non-mechanical) properties. Thermal conductivity is an example of an important functional property of a Thermal Interface Material (TIM) for LED’s and...conference paper 2013

Latsuzbaia, R. (author), Negro, E. (author), Koper, G.J.M. (author)Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...conference paper 2013

Su, J.F. (author), Qiu, J. (author), Schlangen, H.E.J.G. (author)Preservation and renovation bitumen of pavement is a big problem for the whole world. Traditionally, application rejuvenators is the only one method that can restore the original properties of the pavements. However, some puzzles still restrict its successful usage. Microencapsulation is a promising method to apply rejuvenator in bitumen. These...conference paper 2013

Lubelli, B. (author), Nijland, T.G. (author), Van Hees, R.P.J. (author)In the present research a test procedure was set up to reproduce self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens in laboratory. After few months testing, during which the specimens were subjected to wet-dry cycles, thin sections of the specimens were prepared and observed by Polarization and Fluorescence...conference paper 2011

Mors, R.M. (author), Jonkers, H.M. (author)A functional experimental concrete system has been developed in our lab, in which a two component bacteria-based healing agent contained in a protective reservoir is included in the concrete mixture. Incorporated bacteria have the potential to produce copious amounts of calcium carbonate based crystals from supplied mineral precursor compounds....conference paper 2013

Van der Zwaag, S. (author), Zhang, S. (author), Fang, H. (author), Bruck, E. (author), Van Dijk, N.H. (author)We report the main findings of our work on the behaviour of binary Fe-Cu and Fe-Au model alloys designed to explore routes to create new creep resistant steels having an in-built ability to autonomously fill creep induced porosity at grain boundaries. The alloying elements were selected on the basis of their ability to be brought in...conference paper 2016

Sierra Beltran, M.G. (author), Jonkers, H.M. (author), Mors, R.M. (author), Mera-Ortiz, W. (author)This paper describes the first field application of self-healing concrete with alkaliphilic spore-forming bacteria and reinforced with natural fibres. The application took place in the highlands in Ecuador in July 2014. The concrete was cast as linings for an irrigation canal that transports water from glaciers in the Andean mountains to...conference paper 2015

(author)Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene...conference paper 2013

Zemskov, S.V. (author), Copuroglu, O. (author), Vermolen, F.J. (author)A mathematical model for the post-damage recovery of carbonated cement is described. The model is based on a two-dimensional initial-boundary value problem for a system of partial differential equations. The study is embedded within the framework of investigating the effect of using lightweight expanded clay aggregate, which is incorporated into...conference paper 2013

Savija, B. (author), Schlangen, E. (author)Concrete structures are commonly cracked when in service. To overcome issues arising from cracking, self-healing concrete is being developed. Together with the development of the material, techniques to verify and quantify self-healing are being developed. A number of destructive techniques have been used in the past. It would be beneficial to...conference paper 2015
