Brasser, P. (author), Prins Maurits Laboratorium TNO (author)The heat load, imposed by air-permeable NBC (nuclear, biological, and chemical)-protective suits, can be reduced by improving the air permeability of the suit. However, increased air permeability will reduce the chemical protective performance, since increasing the air permeability of the NBC-protective material will result in higher air...article 2004

Donkers, P.A.J. (author), Huinink, H.P. (author), Erich, S.J.F. (author), Reuvers, N.J.W. (author), Adan, O.C.G. (author)Coatings are used in a variety of applications. Last decades more and more coating systems are transforming from solvent to waterborne coating systems. In this study the influence of pigments on the water permeability of a waterborne coating system is studied, with special interest in the possible interfacial layer of additives around the...article 2013

Kudryavtsev, Y.V. (author), Gelinck, E.R.M. (author), Fischer, H.R. (author), TNO Industrie en Techniek (author)A theoretical investigation of van der Waals forces acting between two solid silicon surfaces at separations from zero to approximately 20 nm is presented. We focused our efforts on the analysis of different factors that can cause deviations from the classical pressure-distance dependence p ∼ 1/D3. It is demonstrated that a layer (oxide or water...article 2009

(author)In this study, we have compared the performance of self-aligned a-IGZO thin-film transistors (TFTs) whereby the source/drain (S/D) region's conductivity enhanced in three different ways, that is, using SiNx interlayer plasma (hydrogen diffusion), using calcium (Ca as reducing metal) and using argon plasma (changing the atomic ratio). All these...article 2015

Scheperboer, I.C. (author), Efthymiou, E. (author), Maljaars, J. (author)This paper considers local buckling of perforated square aluminium plates. Plates of various slenderness with simply supported edges and subjected to uniaxial compression are studied using the finite element method. Different perforation patterns are investigated, from a single circular hole to 25 circular holes distributed over the plate. A...article 2016

Dortmans, L.J.M.G. (author), Bos, B. (author), Fischer, H.R. (author), TNO Industrie en Techniek (author)Roofing tiles are traditionally produced via pressing using plaster of Paris moulds. A replacement of such moulds by porous PMMA based moulds increases production speed and the durability of the moulds, however results in a non-acceptable surface finish due to enhanced adhesion of the clay to the porous mould. A much better release of the clay...article 2010

den Bakker, A.J. (author), Werkhoven, R.J. (author), Sillekens, W.H. (author), Katgerman, L. (author)Longitudinal weld seams are an intrinsic feature in hollow extrusions produced with porthole dies. As these joins occur along the entire extruded length, it is desirable that these weld seams have a minimal impact on the structural integrity of the extrudate. In particular, defects associated with weld seam formation should be avoided. In this...article 2014

Hacquebord, A. (author), Lubelli, B.A. (author), van Hees, R.P.J. (author), Nijland, T.G. (author)Rising damp is one of the most recurrent and well-known hazards to existing buildings and monuments. Several types of intervention exist to tackle the problem. Among these, the creation of a damp-proof course against capillary rise by means of injection of chemical products is one of the most diffused methods, thanks to the relatively easy and...article 2013
