Aarts, J. (author), van Ravensteijn, B. (author), Fischer, H. (author), Adan, O. (author), Huinink, H. (author)Non-stabilized thermochemical materials impose several limitations on their use. These include swelling/shrinkage, cracking, and agglomeration over cycles. In addition, the deliquescence transition cannot be used and is even considered an unwanted side effect. In this work several salt hydrates for low temperature heat storage (K2CO3, CaCl2 and...article 2023

Lucarelli, G. (author), de Rossi, F. (author), Taheri, B. (author), Brown, T.M. (author), Brunetti, F. (author)Flexible perovskite solar cells (PSC) represent a viable technology for applications requiring high power-to-weight ratios, seamless integration onto a variety of shapes, and low embedded energy. Strategies to boost the performance of flexible PSC, which still lag behind their rigid counterparts, include passivation of the perovskite surface...article 2022

Biemond, J.J.B. (author), Postoyan, R. (author), Heemels, W.P.M.H. (author), van de Wouw, N. (author)We investigate stability of a solution of a hybrid system in the sense that the graphs of solutions from nearby initial conditions remain close and tend towards the graph of the given solution. In this manner, a small continuous-time mismatch is allowed between the jump times of neighbouring solutions and the ‘peaking phenomenon’ is avoided. We...article 2020

Nieuwenhuizen, R.P.J. (author), Dijk, J. (author), Schutte, K. (author)Long-range imaging with visible or infrared observation systems is typically hampered by atmospheric turbulence. Software-based turbulence mitigation methods aim to stabilize and sharpen such recorded image sequences based on the image data only. Although successful restoration has been achieved on static scenes in the past, a significant...article 2019

(author)Thermochemical heat storage in salt hydrates is a promising method to improve the solar fraction in the built environment. The major concern at this stage is liquefaction followed by washing out of active material and agglomeration into large chunks of salt, thus deteriorating the diffusive properties of the porous salt hydrate structure.
