Eberbach, M.C. (author), Huinink, H.P. (author), Shkatulov, A.I. (author), Fischer, H.R. (author), Adan, O.C.G. (author)The hydration of salts has gained particular interest within the frame of thermochemical energy storage. Most salt hydrates expand when absorbing water and shrink when desorbing, which decreases the macroscopic stability of salt particles. In addition, the salt particle stability can be compromised by a transition to an aqueous salt solution,...article 2023

(author), Hardy, A. (author), Van Bael, M.K. (author), Buskens, P. (author)The switching performance of W/VO2 nanoparticles in thermochromic glass laminates was investigated. W/VO2 powder was prepared, and displayed a phase transition temperature and switching enthalpy of 20.9 °C and 37.5 ± 0.2 J g-1, respectively. Using wet bead milling, the particle size was reduced from 24 ± 2 um to 120 ± 10 nm. In the same process,...article 2023

Mann, D. (author), Yeung, C.P.K. (author), Habets, R. (author), Vroon, Z. (author), Buskens, P. (author)With constantly progressing climate change and global warming, we face the challenge to reduce our energy consumption and CO2 emission. To increase the energy-efficiency in buildings, we developed a thermochromic coating for smart windows which is optimized for intermediate climates.

Koç, Y. (author), Warnier, M. (author), van Mieghem, P. (author), Kooij, R.E. (author), Brazier, F.M.T. (author)Cascading failures are one of the main reasons for blackouts in electric power transmission grids. The economic cost of such failures is in the order of tens of billion dollars annually. The loading level of power system is a key aspect to determine the amount of the damage caused by cascading failures. Existing studies show that the blackout...article 2014

Martin, A.H. (author), Bos, M.A. (author), van Vliet, T. (author), TNO Voeding (author)Interfacial (rheological) properties of soy glycinin were studied at different pH. At acidic and high alkaline pH glycinin (11S form, Mw ∼ 350 kDa) dissociates into smaller subunits, the so called 3S form (Mw ∼ 44 kDa) and 7S form (Mw ∼ 175 kDa). This dissociation behaviour is expected to affect the interfacial rheological properties of glycinin...article 2002
