(author)Earth observation measurements at wavelengths below 320nm are challenging due to the steep decrease of the earth irradiance towards shorter wavelengths. Stray light and ghosting of longer wave light can easily overwhelm the signals at short wavelengths. In the UV channel (270-320nm) of the TROPOMI instrument this challenge has been addressed...conference paper 2017

The influence of calcium and zirconium based secondary driers on drying solvent borne alkyd coatingsErich, S.J.F. (author), Gezici-Koç, Ö. (author), Michel, M.E.B. (author), Thomas, C.A.A.M. (author), van der Ven, L.G.J. (author), Huinink, H.P. (author), Flapper, J. (author), Duivenvoorde, F.L. (author), Adan, O.C.G. (author)Cobalt based driers are the most commonly used primary catalysts in alkyd coatings as they promote fast drying and lead to hard coatings. However, several studies have suggested potential reclassification of cobalt-based alkyd driers. Therefore, cobalt based driers are being replaced by alternatives, e.g. based on iron or manganese. In practice...article 2017

Erich, S.J.F. (author), Baukh, V. (author)Growth of micro-organisms on coated substrates is a common problem, since it reduces the performance of materials, in terms of durability as well as aesthetics. In order to prevent microbial growth biocides are frequently added to coatings. Unfortunately, early release of these biocides reduces the biocidal protection of these coatings....article 2016

(author)Hyperbolic metamaterials (HMMs) are anisotropic materials with a permittivity tensor that has both positive and negative eigenvalues. Here we report that by using a type II HMM as a cladding material, a waveguide that only supports higher-order modes can be achieved, while the lower-order modes become leaky and are absorbed in the HMM cladding....article 2016
