Annema, J.A. (author), De Jong, M. (author)Dit artikel geeft een overzicht van de discussie over transportmodellen in Nederland zoals met name gevoerd in de periode 2007 - 2010. De kern van de discussie is dat transportmodellen zijn overvraagd en dat de inherente onzekerheden in modelresultaten ten onrechte zijn genegeerd. Er lijkt consensus in het debat om voortaan wel de onzekerheid in...journal article 2012

(author)The effect of temperature controlled annealing on the confined valence electron states in CdSe nanocrystal arrays, deposited as thin films, was studied using two-dimensional angular correlation of annihilation radiation. A reduction in the intensity by ?35% was observed in a feature of the positron annihilation spectrum upon removal of the...journal article 2009

(author), Nikolaenko, Y.M. (author), Khokhlov, V.A. (author)Nd0.52Sr0.48MnO3 films of various thicknesses have been prepared by dc magnetron sputtering on single crystal LaAlO3 (001) substrates. Reducing the film thickness leads to a significant suppression of ferromagnetic (FM) ordering and the Curie point falls below the antiferromagnetic (AFM) transition temperature. When this occurs, a huge rise of...journal article 2011

(author)Donut-like crystals of Mg–Al layered double hydroxides (LDH) are synthesized using a hydrothermal method with microwave heating. This morphology provides enlargement of the specific surface area of the {h k 0} faces, needed for adsorption application. The growth mechanism for donut-shaped crystals is proposed on the basis of AFM and STEM–EDX...journal article 2010

Fey, A. (author), Levine, L. (author), Wilson, D.B. (author)A popular theory of self-organized criticality relates driven dissipative systems to systems with conservation. This theory predicts that the stationary density of the Abelian sandpile model equals the threshold density of the fixed-energy sandpile. We refute this prediction for a wide variety of underlying graphs, including the square grid....journal article 2010

Ardic, O. (author), Annema, J.A. (author), van Wee, G.P. (author)The implementation of road pricing policies is dependent on political support for the policy. It is frequently argued that many pricing proposals fail to be implemented due to the opposition of one or a group of policy actors (e.g. political parties, interest groups). This study considers this issue and examines the reasons for non...journal article 2015

(author)We report on a new class of polymer photonic crystal fibers for low-loss guidance of THz radiation. The use of the cyclic olefin copolymer Topas, in combination with advanced fabrication technology, results in bendable THz fibers with unprecedented low loss and low material dispersion in the THz regime.We demonstrate experimentally how the...journal article 2009

(author)We report frequency locking of two 3.5-THz third-order distributed feedback (DFB) quantum cascade lasers (QCLs) by using methanol molecular absorption lines, a proportional-integral-derivative controller, and a NbN bolometer. We show that the free-running linewidths of the QCLs are dependent on the electrical and temperature tuning coefficients....journal article 2012
