Zhang, S. (author), Langelaan, G. (author), Schut, H. (author), Brück, E. (author), Van der Zwaag, S. (author), Van Dijk, N.H. (author)Steels are among the most widely used construction materials as their mechanical properties can be tuned over a very wide range of desired combinations of strength formability and other properties. However, when exposed for long times to high temperatures steel components can exhibit premature and low-ductility creep fracture, which arises from...conference paper 2013

Chen, Z. (author), Xu, Z. (author), Wang, G. (author), Li, H. (author), Chen, B. (author), Zeng, X.C. (author), Tan, L. (author)Crystalline solids are solid materials whose constituent atoms, molecules, or ions are arranged in a highly regulated fashion. Due to lack of rotational freedom in their stacking, they have been known as fragile materials. Even though some efforts have been dedicated to bind or mend defects/cracks in amorphous materials like concrete or polymers...conference paper 2013

(author)Sustainability or environment friendly green technology is based on the use of agents of biological origin that can mimic nature in their process applications. The production and use of conventional Portland cement is significant contributor to emission of greenhouse gases and the resultant global warming. Microbial induced carbonate...conference paper 2013

Zhang, M. (author), Han, N. (author), Xing, F. (author), Wang, X. (author), Schlangen, H.E.J.G. (author)For a microcapsule based self-healing system in the cementitious material, a fundamental issue is to find and facilitate a suitable microcapsule system, concerning either the material selection or design and manufacture process. In this study, urea formaldehyde resin is used for the shell of microcapsule, and bisphenol an epoxy resin E-51...conference paper 2013

Sangadji, S. (author), Wiktor, V.A.C. (author), Jonkers, H.M. (author), Schlangen, H.E.J.G. (author)Bacteria induced calcite precipitation has been proven to be effective in making concrete structure self-healing. In Microlab TU Delft, the concept has been enhanced by developing a liquid bacteria-based concrete repair system. The solution contains calcite precipitating bacteria, nutrients and buffer compound which may demonstrate high...conference paper 2013

Boatemaa, L. (author), Zhou, J. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)Structural ceramics like alumina are usually brittle and sensitive to flaws leading to a reduction in their mechanical properties. This situation is worsened by machining prior to service and during service by contact, which introduces micro cracks and hidden damages. Crack damage can easily be developed in such ceramics when loaded, which often...conference paper 2013

De Vilder, I. (author), Vanneste, M. (author)Self-healing materials have the capabillity to repair (in an early stage) damage, that would finally lead to material failure. This repair or self-healing occurs with the help of a minor external stimulus or autonomously. Depending on the type of application one or the other is more interesting. Nature is the major source of inspiration for his...conference paper 2013

Wiktor, V.A.C. (author), Sangadji, S. (author), Jonkers, H.M. (author), Schlangen, H.E.J.G. (author)Bacterially induced calcium carbonate precipitation has received considerable attention for its potential application in enforcing or repairing construction material. The mechanism of bacterially mediated calcite precipitation in those studies is primarily based on the enzymatic hydrolysis of urea. Besides calcite precipitation, this reaction...conference paper 2013

Pauli, A. (author), Schmets, A.J.M. (author), Kasbergen, C. (author), Varveri, K. (author), Scarpas, A. (author)Bituminous materials form a class of materials that possess the intrinsic ability to selfheal. This self-healing capability is evidenced by the observation that the service life of these materials in the field exceeds the service life as predicted by standard mechanical laboratory tests. This mismatch between laboratory prediction and field...conference paper 2013

BA takes part not only in cleaving the PDMS chains, but also contributes boronic-acid like moieties to the cleaved chain ends, which provide...conference paper 2013
