Gao, Jian (author), Jin, Peng (author), Zhang, Yuze (author), Dong, H. (author), Wang, Ruixing (author)Due to low activity or long mineralization time, traditional mineral agents for self-healing concrete generally need a long time to achieve a desired repair efficiency. Inspired by epoxy resin AB glue which can consolidate in a short time when mixing the two components together, a novel type of fast-responsive capsules based on two soluble...journal article 2022

Tabakovic, A. (author), Mohan, Joseph (author), Karač, Aleksandar (author)This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as a new extrinsic self-healing asphalt method. The capsules combine two existing self-healing asphalt technologies: (1) rejuvenator encapsulation and (2) induction heating to create a self-healing system that will provide rapid and...journal article 2021

Casquero, Hugo (author), Bona-Casas, Carles (author), Toshniwal, D. (author), Hughes, Thomas J.R. (author), Gomez, Hector (author), Zhang, Yongjie Jessica (author)We extend the recently introduced divergence-conforming immersed boundary (DCIB) method [1] to fluid-structure interaction (FSI) problems involving closed co-dimension one solids. We focus on capsules and vesicles, whose discretization is particularly challenging due to the higher-order derivatives that appear in their formulations. In two...journal article 2021

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Schlangen, E. (author)Self-healing asphalt, which is designed to achieve autonomic damage repair in asphalt pavement, offers a great life-extension prospect and therefore not only reduces pavement maintenance costs but also saves energy and reduces CO<sub>2</sub> emissions. The combined asphalt self-healing system, incorporating both encapsulated rejuvenator and...journal article 2021

Steijlen, A.S.M. (author), Bastemeijer, J. (author), Nederhoff, R.J. (author), Jansen, K.M.B. (author), French, P.J. (author), Bossche, A. (author)Ammonium levels in sweat can potentially be used to measure muscle fatigue and to diagnose particular metabolic myopathies. To research the potential use of ammonia in sweat as a biomarker, a new real-time monitoring system is developed. This system consists of a capsule that is placed on the skin and ventilated with dry air. A metal-oxide...journal article 2021

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Lin, P. (author), Zhang, Y. (author), Nahar, S. (author), Lommerts, B. J. (author), Schlangen, E. (author)Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack. When the microcrack encounters the capsule, the fracture energy at the tip opens the capsule and releases the...journal article 2021

Xu, S. (author)Porous asphalt, due to its advantages of noise reduction and water drainage, is widely used in the surface layer of the highway in the Netherlands. However, the porous structure makes it prone to ravelling, therefore more frequent maintenance and reconstruction than other asphalt mixtures The porous asphalt service life can be extended with self...doctoral thesis 2020

Liebrand, Luka C. (author), van Wingen, Guido A. (author), Vos, F.M. (author), Denys, Damiaan (author), Caan, Matthan W.A. (author)Given the restricted total scanning time for clinical neuroimaging, it is unclear whether clinical diffusion MRI protocols would benefit more from higher spatial resolution or higher angular resolution. In this work, we investigated the relative benefit of improving spatial or angular resolution in diffusion MRI to separate two parallel...journal article 2020

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Schlangen, E. (author)Self-healing asphalt, aimed to produce a sustainable asphalt pavement using green technology, has been studied in the past two decades. Technologies including encapsulated rejuvenator and induction heating have been proposed, demonstrated in the laboratory, and gradually evaluated in field application. This paper looks into the synergy effect...journal article 2020

(author), Šavija, B. (author)In this study, the interface between different types of bacteria-embedded self-healing polylactic acid capsules (PLA) and cement paste is investigated. Particularly, the changes in microstructure and mechanical properties of the interface with respect to bulk cement paste were studied. First, nanoindentation was performed to obtain maps of...journal article 2020

Bunt, Riccardo (author)During the design and analysis of a mission characterised by re-entry flight, consistent effort and resources are invested in the definition of the aerodynamic database of the re-entry vehicle. An aerodynamic database collects a set of dimensionless coefficients that describe the interaction of the vehicle's geometry and airflow, and an accurate...master thesis 2019

Beydilli, Esad (author), Abdellaoui, Zakaria (author)Endoscopic devices are used in the medical world to inspect the gastrointestinal tract. Because there are some complications with wired endoscopy, such as reaching the small intestine, there is a need for new methods to do endoscopy. Therefore an endoscopic pill is invented which can be used to do measurements in the gastrointestinal tract. This...bachelor thesis 2019

Wolfs, Rimsky (author)Meteors have been observed by accident from geostationary orbit (GEO). It is of interest for surveillance, meteor science and the updating of empirical models to know what instruments are needed on a GEO satellite to observe meteors and re-entering capsules in Earth ‘s atmosphere. A re-entry simulation code is written to fill the gap of missing...master thesis 2019

Xu, S. (author), Liu, X. (author), Tabaković, Amir (author), Schlangen, E. (author)Improving the healing capacity of asphalt is proving to be an effective method to prolong the service life of an asphalt pavement. The calcium alginate capsules encapsulating rejuvenator have been developed and proved to provide successful localized crack healing in asphalt mastic. However, it is not known whether this self-healing asphalt...journal article 2019

Xu, S. (author), Tabakovic, A. (author), Liu, X. (author), Palin, D. (author), Schlangen, E. (author)It has been demonstrated that calcium alginate capsules can be used as an asphalt healing system by pre-placing rejuvenator (healing agent) into the asphalt mix and releasing the rejuvenator on demand (upon cracking). This healing mechanism relies on the properties of capsules which are determined by the capsule preparation process. In this...journal article 2019
