Abrahami, S.T. (author), Hauffman, T. (author), de Kok, John M.M. (author), Terryn, H.A. (author), Mol, J.M.C. (author)The long-term strength and durability of an adhesive bond is dependent on the stability of the oxide-adhesive interface. As such, changes in the chemistry of the oxide and/or the adhesive are expected to modify the interfacial properties and affect the joint performance in practice. The upcoming transition to Cr(VI)-free surface pretreatments...journal article 2017

Naghdy, Soroosh (author), Pirgazi, Hadi (author), Verleysen, Patricia (author), Petrov, R.H. (author), Kestens, L.A.I. (author)International Union of Crystallography. The aim of this paper is to examine the morphological and crystallographic anisotropy that develops during high-pressure torsion (HPT) processing. Commercially pure aluminium was subjected to monotonic HPT deformation at room temperature. The microstructure and texture were studied by large-area electron...journal article 2017

Ghodrat, S. (author), Riemslag, A.C. (author), Kestens, L.A.I. (author)Orientation contrast microscopy (i.e., electron backscattered diffraction, EBSD) was employed to monitor the plastic strain in loaded tensile samples of aluminium alloy Al6061 in T4 condition. The kernel average misorientation (KAM) is known to be an appropriate parameter in orientation contrast microscopy which has the potential to characterise...journal article 2017

Denies, L. (author), Zandbergen, B.T.C. (author), Natale, P. (author), Ricci, D. (author), Invigorito, M. (author)Methane is a promising propellant for liquid rocket engines. As a regenerative coolant, it would be close to its critical point, complicating cooling analysis. This study encompasses the development and validation of a new, open-source computational fluid dynamics (CFD) method for analysis of methane cooling channels. Validation with...conference paper 2016

Den Besten, J.H. (author)Crew transfers, surveillance duties and {security, rescue, interception} operations at sea typically require high-speed craft. Aluminium is quite often selected as hull structure material because of its weight save potential in comparison to steel. The fatigue strength, however, may become a point of concern because of the decreased Young’s...doctoral thesis 2015

Herfst, R. (author), Dekker, B. (author), Witvoet, G. (author), Crowcombe, W.E. (author), de Lange, D. (author), Sadeghian Marnani, H. (author)One of the major limitations in the speed of the atomic force microscope (AFM) is the bandwidth of the mechanical scanning stage, especially in the vertical (z) direction. According to the design principles of “light and stiff” and “static determinacy,” the bandwidth of the mechanical scanner is limited by the first eigenfrequency of the AFM...journal article 2015

Demontis, V. (author), Sanna, C. (author), Melskens, J. (author), Santbergen, R. (author), Smets, A.H.M. (author), Damiano, A. (author), Zeman, M. (author)Thin oxide interlayers are commonly added to the back reflector of thin-film silicon solar cells to increase their current. To gain more insight in the enhancement mechanism, we tested different back reflector designs consisting of aluminium-doped zinc oxide (ZnO:Al) and/or hydrogenated silicon oxide (SiOx:H) interlayers with different metals ...journal article 2013

De Visser, P.J. (author), Baselmans, J.J.A. (author), Yates, S.J.C. (author), Diener, P. (author), Endo, A. (author), Klapwijk, T.M. (author)We have measured the number of quasiparticles and their lifetime in aluminium superconducting microwave resonators. The number of excess quasiparticles below 160?mK decreases from 72 to 17??m?3 with a 6?dB decrease of the microwave power. The quasiparticle lifetime increases accordingly from 1.4 to 3.5?ms. These properties of the superconductor...journal article 2012

Vercruyssen, N. (author), Barends, R. (author), Klapwijk, T.M. (author), Muhonen, J.T. (author), Meschke, M. (author), Pekola, J.P. (author)We demonstrate an increased quasiparticle recombination time in superconducting resonators on a SiNx membrane, compared to identical resonators on a SiNx/Si wafer. An interpretation is given using a thermal model of the membrane. Using an array of tunnel junctions to cool or heat the membrane, we show that the resonators on the membranes are...journal article 2011

De Visser, P.J. (author), Withington, S. (author), Goldie, D.J. (author)A model is presented for readout-power heating in kinetic inductance detectors. It is shown that the power dissipated by the readout signal can cause the temperature of the quasiparticle system in the superconducting resonator to switch between well-defined states. At low readout powers, only a single solution to the heat balance equation exists...journal article 2010

Atamanenko, T.V. (author)This thesis deals with grain refinement under the influence of ultrasonic-driven cavitation in aluminium casting processes. Three major goals of this research were: (1) to identify the mechanism of the cavitation-aided grain refinement at different stages of solidification; (2) to reveal the conditions of the stable grain refinement effect in...doctoral thesis 2010

Jäger, K. (author), Zeman, M. (author)We present a mathematical model that relates the surface morphology of randomly surface-textured thin films with the intensity distribution of scattered light. The model is based on the first order Born approximation [see e.g., M. Born and E. Wolf, Principles of Optics, 7th ed. (Cambridge University Press, Cambridge, England, 1999) ] and on...journal article 2009

Ernst, M.A. (author)To ensure a continuing miniaturization in the semiconductor industry, new technologies need to be developed to define ever smaller patterns on the silicon substrates. One of these emerging technologies is extreme ultraviolet (EUV) lithography. Unfortunately, EUV light causes oxidation of the optical components inside the lithography machine that...doctoral thesis 2009

(author)A procedure has been implemented for a quantitative aluminum-doping profiling of µm-scale aluminum-induced solid-phase-epitaxy (SPE) Si islands formed at 400°C. The aluminum concentration was measured to be 1–2×1019 cm?3, which is about 10 times higher than previously reported electrical activation levels. The elemental concentration was...journal article 2008

Khalili Amiri, P.K. (author), Rejaei, B. (author), Vroubel, M. (author), Zhuang, Y. (author)The authors report on the observation of nonreciprocal spin wave propagation in a thin ( ? 200?nm) patterned Ni–Fe stripe. The spin wave transmission spectrum is measured using a pair of microstrip lines as antennas. The nonreciprocity of surface wave dispersion brought about by an adjacent aluminum ground leads to a nonreciprocal coupling of...journal article 2007
