de Gijsel, S.L. (author), Vijn, A.R.P.J. (author), Tan, R.G. (author)This paper proposes an algorithm to localize a magnetic dipole using a limited number of noisy measurements from magnetic field sensors. The algorithm is based on the theory of compressed sensing, and exploits the sparseness of the magnetic dipole in space. Beforehand, a basis consisting of magnetic dipole fields belonging to individual dipoles...article 2022

Nicasy, R. (author), Huinink, H.P. (author), Erich, S.J.F. (author), Adan, O.C.G. (author)An improved High-Speed NMR profiling method is introduced that enables to measure capillary action in thin, non-transparent porous media. Liquid profiles can be measured as fast as 10 ms with a spatial resolution of 14.5 µm. Capillary absorption of microliter-sized droplets into non-transparent nylon-6,6 porous membranes was studied. In nylon-6...article 2021

Neural representations of haptic object size in the human brain revealed by multivoxel fMRI patternsPerini, F. (author), Powell, T. (author), Watt, S.J. (author), Downing, P.E. (author)The brain must interpret sensory input from diverse receptor systems to estimate object properties. Much has been learned about the brain mechanisms behind these processes in vision, but our understanding of haptic perception remains less clear. Here we examined haptic judgments of object size, which require integrating multiple cutaneous and...article 2020

(author)In addition to the desired aesthetical properties, a coating is applied to protect against weathering. A coating prevents moisture accumulation in wood by reducing the water uptake into the wood by its barrier function. The studies in the coating permeability has gained interest with the shift towards waterborne coatings, which make coatings...article 2019

Kuijpers, C.J. (author), Huinink, H.P. (author), Tomozeiu, N. (author), Erich, S.J.F. (author), Adan, O.C.G. (author)Due to the increased use of nanoparticles in everyday applications, there is a need for theoretical descriptions of particle transport and attachment in porous media. It should be possible to develop a one dimensional model to describe nanoparticle retention during capillary transport of liquid mixtures in porous media. Water-glycerol...article 2018

Gezici-Koç, Ö. (author), Erich, S.J.F. (author), Huinink, H.P. (author), van der Ven, L.G.J. (author), Adan, O.C.G. (author)An important reason to apply coatings on wood is to protect wood against moisture. As a result of regulations and ecological concerns, there has been a shift towards waterborne coatings, which make coatings intrinsically more sensitive to water. As a consequence of the higher sensitivity to water, the durability of both wood and coatings can be...article 2018

(author)Carcinogenic chromates are phased out as corrosion inhibitors in organic coatings, and are replaced by benign alternatives. Cerium-based compounds are excellent corrosion inhibitors in an aqueous environment. However, whether they are effective as corrosion inhibitor in an organic coating also depends on their interaction with the coating matrix...article 2014
