(author), Oefner, P.J. (author)A sensitive, selective, and comprehensive method for the quantitative determination of tryptophan and 18 of its key metabolites in serum, urine, and cell culture supernatants was developed. The analytes were separated on a C18 silica column by reversed-phase liquid chromatography and detected by electrospray ionization tandem mass spectrometry...journal article 2011

Gaitas, A. (author), Gianchandani, S. (author), Zhu, W. (author)Thermomechanical analysis (TMA) is widely used to characterize materials and determine transition temperatures and thermal expansion coefficients. Atomic-force microscopy (AFM) microcantilevers have been used for TMA. We have developed a micromachined probe that includes two embedded sensors: one for measuring the mechanical movement of the...journal article 2011

Zhu, Z. (author), Van Tooren, M.J.L. (author), Van der Elst, S.W.G. (author)Based on the use of dedicated software tools, Knowledge Based Engineering (KBE) techniques are able to capture and reuse engineering product and process knowledge to reduce time and cost during product development. In this paper a conceptual design of an automatic wire harness routing application is proposed, based on KBE. As the core of this...conference paper 2011

Zhu, W. (author), Park, J.S. (author), Sessler, J.L. (author), Gaitas, A. (author)Substantial effort has been devoted to the synthesis of molecular receptors that can function as chemosensors for nitroaromatic explosives. In spite of several advantages, these receptors suffer from low sensitivity and difficulties translating the response into the gas phase. We have combined tetrathiafulvalene-functionalized calix[4]pyrrole, a...journal article 2011

Zhu, S. (author), Zijlstra, T. (author), Golubov, A.A. (author), Van den Bemt, M. (author), Baryshev, A.M. (author), Klapwijk, T.M. (author)The coupling efficiency of a Nb superconducting transmission line has been measured using a Fourier transform spectrometer for different magnetic fields. It is found that the coupling decreases with increasing magnetic field when the frequency is close to the gap of the Nb superconductor. This is attributed to the changes of the surface...journal article 2009

Gaitas, A. (author), Zhu, W. (author), Gulari, N. (author), Covington, E. (author), Kurdak, C. (author)Metal microbolometers, used in scanning thermal microscopy, were microfabricated from <20?nm titanium thin films on SiO2/Si3N4/SiO2 cantilevers. These thin films are near the metal-insulator transition regime such that as the film thickness decreases—the resistance increases and the current-voltage characteristics cross over from sublinear to...journal article 2009

Lodewijk, C.F.J. (author), Zijlstra, T. (author), Zhu, S. (author), Mena, F.P. (author), Baryshev, A.M. (author), Klapwijk, T.M. (author)We study, using niobium-technology, the bandwidth of SIS mixers operating at frequencies close to the energy-gap frequency. Microstriplines of niobium-silicon dioxide-niobium have different properties for the top and bottom superconductor, which we find to depend on the used fabrication process. Replacing the AlOx tunnel barrier by AlN, the...journal article 2009

Zhu, J. (author), Zhang, W. (author), Bassir, D.H. (author)The aim of this paper is to enhance the validity of existing evolutionary topology optimization procedures. As this hard-killing scheme related to the element sensitivity values may lead to incorrect predictions of inefficient elements to be removed and the value of the objective function becomes sharply deteriorated during the iterations, a...journal article 2009

(author), West, D.V. (author), Cava, R.J. (author)We report the characterization of layered 2H-type CuxTaS2 for 0?x?0.12. The charge density wave (CDW), at 70 K for TaS2, is destabilized with Cu doping. The sub-1 K superconducting transition in undoped 2H-TaS2 jumps quickly to 2.5 K at low x, increases to 4.5 K at the optimal composition Cu0.04TaS2, and then decreases at higher x. The...journal article 2008

Van Miltenburg, A. (author), Gascon, J. (author), Zhu, W. (author), Kapteijn, F. (author), Moulijn, J.A. (author)The adsorption of propylene and propane on zeolite NaX with and without a saturated (36 wt%) amount of CuCl have been investigated. The single component adsorption isotherms could be well described with a Dual-Site Langmuir model. The dispersion of CuCl results in a decrease of the maximum adsorption capacity of the zeolite for both components....journal article 2008

Zhu, Y. (author)Numerous flood disasters occur every year worldwide, mostly resulting from failure of dikes, some with catastrophic outcomes. Examples are the dike failures along the Yangtze River in China in 1931 due to heavy rainstorms and those in the Netherlands in 1953 due to a storm surge at the North Sea. Both floods induced many deaths and enormous...doctoral thesis 2006

Zhu, L. (author)In this dissertation we study the surface temperature excess in heterogeneous catalysis. For heterogeneous reactions, such as gas-solid catalytic reactions, the reactions take place at the interfaces between the two phases: the gas and the solid catalyst. Large amount of reaction heats are released at the interface for strong exothermic...doctoral thesis 2005
