Andringa, A.-M. (author), Smits, E.C.P. (author), Klootwijk, J.H. (author), de Leeuw, D.M. (author)We present a functional real-time NO2 sensor based on a ZnO field-effect transistor. The dynamic response of the sensor is calculated using a phenomenological charge trapping model, using only experimentally determined parameters. This analytical model is implemented in the sensor protocol to create a hardware demonstrator sensor. We show that...article 2013

Veninga, E.P. (author), Kregting, R. (author), van der Waal, A. (author), Gielen, A.W.J. (author)The introduction of new materials or technologies can have an enormous impact on the Time to Market (TTM) of new products. Preferably, the performance of new materials or technologies is known before these are designed into a product. This paper presents a reliability assessment approach which has been developed with the aim to reduce the so...conference paper 2013

Forquin, P. (author), Riedel, W. (author), Weerheijm, J. (author)Owing to their low tensile failure strain, concrete is a difficult material to test under dynamic tensile loading. Indeed, conventional testing apparatuses such as high-speed hydraulic presses or Split Hopkinson Bar facilities rely on a mechanical balance of the specimen implying a short round-trip time in the specimen in comparison with the...bookPart 2013

(author)Thermal evaporation is the current standard for the manufacture of small molecule organic light emitting diodes (smOLEDs), but it requires vacuum process, complicated shadow masks and is inefficient in material utilization, resulting in high cost of ownership. As an alternative, wet solution deposition can provide significant cost savings by...article 2013

van der Wal, R. (author), Rahm, M. (author), Hiltz, J. (author), Claesson, A. (author), Boonacker, B. (author)Navies have been facing budget reductions over the past decade. Since crew size is a major cost driver, this has led to efforts to reduce manning on board naval ships. Traditionally, damage control and firefighting were manpower intensive operations. To enable crewing level reductions without compromising the ability to deal with damage and...conference paper 2013

del Pozo de Dios, E. (author), Lázaro, I. (author), Delannoy, P. (author), Thomson, R. (author), Versmissen, A.C.M. (author), van Nunen, E. (author)Structural interaction has been one of the critical issues for improved frontal impact protection. An evaluation procedure for structural interaction has been difficult to develop using objective test data procedures. While previous research with the PDB barrier has been promising based on subjective evaluations, an objective assessment criteria...conference paper 2013

van Deventer, H.C. (author), Houben, R.J. (author), Koldeweij, R.B.J. (author)A new atomization nozzle based on ink jet technology is introduced for spray drying. Application areas are the food and dairy industry, in the first instance, because in these industries the quality demands on the final powders are high with respect to heat load, powder shape, and size distribution. The ink jet nozzles can atomize fluids with a...article 2013

Woldman, M. (author), van der Heide, E. (author), Tinga, T. (author), Masen, M.A. (author)This work focuses on the relation between the properties of abrasive bodies and the wear they cause. By performing single asperity scratch tests to simulate abrasive wear, the wear process takes place in a controlled environment, allowing the properties of the abrasive body to be isolated and studied independently. The setup used is a pin-on...article 2013

Erkamp, C.J.M. (author)Het werkterrein van TNO is aanzienlijk breder dan de tuinbouw alleen. Maar onderzoek in 'vreemde sectoren' levert geregeld inzichten op die wel weer bruikbaar zijn voor toepassingen in de teelt van groenten, bloemen en planten. In elke editie van GTT Magazine reikt TNO een voorbeeld aan. Dit keer een uitstapje naar de LED-verlichting.article 2013
