Craciun, N.I. (author), Wildeman, J. (author), Blom, P.W.M. (author), TNO Industrie en Techniek (author)We report on the synthesis and electrical characterization of polyfluorene-triarylamine-based hole transport layers (HTLs). The solubility of the HTL can be tuned by adjustment of the chemical structure without loss of the charge transport properties. Double-layer polymer light-emitting diodes are constructed with an HTL that is not soluble in...article 2010

van Put, M.A. (author), de Jong, J.D. (author)Bij houten weg- en water bouwconstructies blijft er vaak water staan tussen aansluitingen van constructiedelen. Het vochtgehalte van het hout stijgt, met versnelde materiaaldegradatie tot gevolg. De ontwateringsplaat, een innovatie van TNO, gaat houtrot op verbindingspunten tegenarticle 2015

(author), Kelly, T.F. (author)Open-space nanomaterials are a widespread class of technologically important materials that are generally incompatible with analysis by atom probe tomography (APT) due to issues with specimen preparation, field evaporation and data reconstruction. The feasibility of encapsulating such non-compact matter in a matrix to enable APT measurements is...article 2015

Fischer, H.R. (author), Gelinck, E.R.M. (author)Surfaces tend to be made smoother in order to gain flatness or in order to fulfill the need for more precise and reproducible positioning of parts. Adhesion or even sticking of the surfaces is a major showstopper for these applications. There are several measures that can be taken in order to reduce spontaneous adhesion. Quantification of the...article 2012

van Nijnatten, P.A. (author), Technisch Physische Dienst TNO - TH (author)Solar and visual light transmittance, colour appearance and other optical properties of glazing, are according to present standards specified for (near-) normal incidence. In general however, these properties are angular dependent. Realistic computation of visual light and solar energy properties therefore requires the angular behaviour to be...article 1999

van Kuilenburg, J. (author), Masen, M.A. (author), van der Heide, E. (author)The friction behaviour of the human fingerpad as a function of asperity geometry was investigated experimentally. Surface textures consisting of evenly distributed spherically tipped asperities were used for in vivo testing. Using analytical expressions, a multi-scale model was developed to explain the observed friction behaviour as a function...article 2013

Pruiksma, J.P. (author), Breunese, J.N. (author), van Thienen-Visser, K. (author), de Waal, J.A. (author)This paper presents a new formulation of the Rate Type Compaction Model (RTCM) for sandstone based on the isotach concept. The RTCM was originally developed to explain the loading rate dependent compaction behaviour observed in laboratory test on unconsolidated and consolidated sandstone samples and the delayed subsidence behaviour above...article 2015

Hofmeier, H. (author), El-Ghayoury, A. (author), Schubert, U.S. (author), TNO Industrie en Techniek (author)Terpolymers based on poly(methyl methacrylate), containing terpyridinemoieties as well as epoxide groups, were synthesized via free-radical polymerization. The products were cross-linked non-covalently with iron(II) ions and covalently by treatment with AlCl3. Both steps could be combined in different order. The non-covalent cross-linking could...article 2003

Theelen, M.J. (author), Habets, D. (author), Staemmler, L. (author), Winands, H. (author), Bolt, P.J. (author)Organosilicon coatings provide good optical and mechanical properties and are excellent candidates for the modification of the surface energy of polymers. These coatings can be deposited by plasma polymerization of hexamethyldisiloxane (HMDSO) under atmospheric pressure and at room temperature. The resulting films can range from soft,...article 2012

(author), TNO Industrie en Techniek (author)Cadmium (Cd) has been extensively used as an excellent corrosion protective coating for steel applications in aerospace, automotive, electrical and fasteners industries. However, Cd is banned due to its toxic nature and strict environmental regulations. In this study, the coating morphology and corrosion resistance of alternative,...article 2008

(author)This paper describes a combination of photonic annealing and compression rolling to improve the conductive properties of printed binder-based graphene inks. High-density light pulses result in temperatures up to 500 °C that along with a decrease of resistivity lead to layer expansion. The structural integrity of the printed layers is restored...article 2016

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
