Heerings, J.H.A.M. (author), den Herder, A.J. (author)The RIMAP project is aimed at the establishment of an European RBMI framework including the assessment of the Consequence of Failure (CoF). Although the RIMAP framework allows the use of various methods provided they meet certain requirements, specific methods to assess the CoF have been developed. Both for a screening analysis and a detailed...article 2004

(author)This paper concentrates on observations of the surface topography by scanning electron microscopy (SEM) on alloyed and stainless steels samples treated by ultrashort laser pulses with duration of 210 fs and 6.7 ps. Globular-like and jet-like objects were found depending on the various levels of the fluence applied. It is shown that these...article 2011

Vink, P. (author), Rotteveel, R.T. (author), Wisse, J.D.M. (author), Kunstoffen en Rubber Instituut TNO (author)Plastic crates will deteriorate and ultimately fail due to brittle fracture if, either during use or storage, they are exposed to sunlight. The time to failure depends on the UV stability of the polymer used, but in particular also on the conditions of use, such as time of exposure, height of the stack during stocking, rate of circulation and...article 1985

Manders, W. (author), Maljaars, J. (author), Belin, B. (author), Lukic, M. (author)The strength and stability of aluminium structures are expected to be determined with formulas from the design standards for aluminium structures. In Europe, the latter are represented by Eurocode 9. In case structural components are made of hollow sections, widely used in the aluminium built environment, Eurocode 9 does not provide design rules...article 2019

Poodt, P.W.G. (author), Illiberi, A. (author), Roozeboom, F. (author)Spatial atomic layer deposition can be used as a high-throughput manufacturing technique in functional thin film deposition for applications such as flexible electronics. This, however, requires low-temperature deposition processes. We have investigated the kinetics of low-temperature (< 100 C) spatial atomic layer deposition of alumina from tri...article 2013

Polder, R.B. (author), Peelen, W.H.A. (author), TNO Bouw (author)Concrete prisms were made with four cement types including cements with fly ash and/or blast furnace slag and three waterto- cement (w/c) ratios. Chloride penetration and corrosion of rebars were stimulated by subjecting prisms to cyclic loading with salt solution and drying. Concrete resistivity, steel potentials and corrosion rates were...article 2002

van Velden, P.F. (author), Centraal Laboratorium TNO (author)Considerable amounts of MgCO<sub>3</sub> may appear in alkali metal carbonate melts in contact with MgO and carbon dioxide gas. The equilibrium between dissolved MgCO<sub>3</sub>, MgO and carbon dioxide gas has been studied. The results satisfactorily obey thermodynamic theory based upon a melt model used by Förland for the similar system with...article 1967

van Deelen, J. (author), Frijters, C. (author)We have investigated the benefit of a patterned metallization on top of a transparent conductive oxide in CIGS thin-film solar panels. It was found that cells with a grid have a higher efficiency compared to cells with only a TCO. This was observed for all cell lengths used. Furthermore, metallic grids enable increase of the cell length up to 10...article 2017

van Deelen, J. (author), Frijters, C. (author), Suijlen, M. (author), Barink, M. (author)The effect of the front contact characteristics on the working of monolithically integrated thin film solar panels and effective ways of improving the front contact are discussed. Efficiencies were calculated for various cell lengths and scribing areas in between cells (interconnection dead zone widths). The application of a metallic grid was...article 2015

(author)The feasibility of the inspection of flow line hubs using the phased array technique was investigated to determine the surface area of the seal area degraded by corrosion. A clean model of the hub was simulated to gain insight into the geometrical echoes and to determine the area covered by the ultrasonic beams. A finite difference scheme was...article 2011

Granneman, S.J.C. (author), Shahidzadeh, N. (author), Lubelli, B.A. (author), van Hees, R.P.J. (author)Borax has been identified as a possible crystallization modifier for sodium sulfate. Understanding the effect of borax on factors influencing transport and crystallization kinetics of sodium sulfate helps to clarify how this modifier might limit crystallization damage. It has been observed that the addition of borax to sodium sulfate solutions...article 2017

van Deelen, J. (author), Omar, A. (author), Barink, M. (author)The conductivity of transparent front contacts can be improved by patterned metallic nanowires, albeit at the cost of optical loss. The associated optical penalty can be strongly reduced by texturization of the cell stack. Remarkably, the nanowires themselves are not textured and not covered in our design. This was shown by optical modeling...article 2017

TNO Bouw (author)Houten kozijnen hebben het in de traditionele woningbouw vaak zwaar te verduren. Omdat inmetselkozijnen al vrciieg in het bouwproces worden geplaatst, is het op het eind zeer moeilijk dé eens door de _ timmerfabrikant geleverde kwaliteit te garanderen. Een nieuw systeem met de naam Kapla (KAnt-en-klaar PLAatsek) maakt hier een eind aan.article 1999
