1. The role of universities in innovation networks: the role of proximity on innovation dynamics in knowledge community precints - Korotka, M.; Benneworth, Paul; Ratinho, Tiago
This paper critically analyses the recent fad for using technopoles and as key economic growth drivers stimulating innovation dynamics in particular territories. Conceptualising technopoles as “knowledge community precincts” creating science-park style benefits, we characterise these benefits as creating proximity between participants. Studying a typical science city, Kennispark in Eastern Netherlands, we discover that geographical proximity is much less important than social, cognitive or institutional proximity to Kennispark academics. The paper argues that local dimension to technopoles requires further analysis, and policy should focus on embedding local firms more actively in technopoles’ knowledge communities.

3. SuchThatCast Episode 5: Peter Asaro - Søraker, J.H.
Peter Asaro is Assistant Professor at the School of Media Studies in the New School for Public Engagement, New York, specializing in philosophy of science, technology and media. His work examines the interfaces between social relations, human minds and bodies, artificial intelligence and robotics, and digital media. His current research focuses on the social, cultural, political, legal and ethical dimensions of military robotics and UAV drones, from a perspective that combines media theory with science and technology studies. Although dealing with topics similar to previous guests Noel Sharkey and Wendell Wallach, Asaro comes at it from a very different perspective...

4. On-Chip Tungsten Oxide Nanowires Based Electrodes for Charge Injection - Agiral, Anil; Gardeniers, J.G.E. (Han)

5. Gas–liquid dynamics at low Reynolds numbers in pillared rectangular micro channels - Loos, S.R.A. de; Schaaf, J. van der; Tiggelaar, R.M.; Nijhuis, T.A.; Croon, M.H.J.M. de; Schouten, J.C.
Most heterogeneously catalyzed gas–liquid reactions in micro channels are chemically/kinetically limited because of the high gas–liquid and liquid–solid mass transfer rates that can be achieved. This motivates the design of systems with a larger surface area, which can be expected to offer higher reaction rates per unit volume of reactor. This increase in surface area can be realized by using structured micro channels. In this work, rectangular micro channels containing round pillars of 3 μm in diameter and 50 μm in height are studied. The flow regimes, gas hold-up, and pressure drop are determined for pillar pitches of 7, 12,...

6. Errata: Fokker, a clash of culture - Heerkens, Hans; Ulijn, Jan
What role do cultural play in the survival of companies that face existential problems? We try to provide some answers by looking at the decline of the Dutch aircraft manufacturer Fokker. In 1996 this company went bankrupt and among the causes of this event cultural factors rank high, at least at first sight. We show that differences in national culture could have played a role in one of the defining moments in Fokker's existence: the failed take-over by the German aerospace giant Deutsche Aerospace (DASA). But we also show that an over-ambitious management was responsible for the situation in which...

7. Editorial "Special Issue - IMRET 11: 11th International Conference on Microreaction Technology" - Kusakabe, K.; Gardeniers, J.G.E. (Han); Gavriilidis, A.; Hessel, V.; Okamoto, K.; Sotowa, K.-I.; Watts, P.; Yoshida, J.-i.

8. A Supramolecular Sensing Platform for Phosphate Anions and an Anthrax Biomarker in a Microfluidic Device - Eker, Bilge; Yilmaz, Mahmut Deniz; Schlautmann, Stefan; Gardeniers, Johannes G.E.; Huskens, Jurriaan
A supramolecular platform based on self-assembled monolayers (SAMs) has been implemented in a microfluidic device. The system has been applied for the sensing of two different analyte types: biologically relevant phosphate anions and aromatic carboxylic acids, which are important for anthrax detection. A Eu(III)-EDTA complex was bound to β-cyclodextrin monolayers via orthogonal supramolecular host-guest interactions. The self-assembly of the Eu(III)-EDTA conjugate and naphthalene β-diketone as an antenna resulted in the formation of a highly luminescent lanthanide complex on the microchannel surface. Detection of different phosphate anions and aromatic carboxylic acids was demonstrated by monitoring the decrease in red emission following...

9. A bio-inspired hair- based acceleration sensor - Droogendijk, Harmen
Crickets use so-called clavate hairs to sense (gravitational) acceleration to obtain information on their orientation. Inspired by this clavate hair system, a one-axis biomimetic accelerometer has been developed and fabricated using surface micromachining and SU- 8 lithography. Measu- rements show that this MEMS hair-based accelerometer has a resonance frequency of 320 Hz, a detection threshold of 0.10 m/s2 and a dynamic range of more than 35 dB. The accelerometer exhibits a clear directional response to external accelerations.

10. Developing an integrated technology roadmapping process to meet regional technology planning needs: the e-bike pilot study - Cowan, Kelly R.; Daim, Tugrul U.; Walsh, Steven T.
Smart grid is a promising class of new technologies offering many potential benefits for electric utility systems, including possibilities for smart appliances which can communicate with power systems and help to better match supply and demand. Additional services include the ability to better integrate growing supplies of renewable energy and perform a variety of value-added services on the grid. However, a number of challenges exist in order to achieving these benefits. Many utility systems have substantial regulatory structures that make business processes and technology innovation substantially different than in other industries. Due to complex histories regarding regulatory and deregulatory efforts, and due...

18. Affecting the world or affecting the mind? - Soraker, Johnny Hartz

19. The neglect of reason : a plea for rationalist accounts of the effects of virtual violence - Soraker, Johnny Hartz
The purpose of this paper is to discuss how experiencing virtual violence might lead to changes in our moral judgments through a process of rational deliberation. This perspective is proposed as a complementary alternative to the dominant tendency in current research to exclusively focus on how virtual violence affects our emotions as behavioural dispositions. I will propose and consider a rationalist, descriptive account that is based on sound principles for case-based reasoning. The controversial notion of ‘virtual rape’ will be used as an example of how the rationalist and emotivist accounts ask fundamentally different questions and how the proposed account...

20. Oxidative Conversion of Hexane to Olefins-Influence of Plasma and Catalyst on Reaction Pathways - Boyadjian, C.; Agiral, A.; Gardeniers, J.G.E.; Lefferts, L.; Seshan, K.
An integrated plasma-Li/MgO system is efficient for the oxidative conversion of hexane. In comparison to the Li/MgO catalytic system, it brings considerable improvements in the yields of light olefins (C 2 = –C 5 = ) at relatively low temperatures indicating synergy from combination of plasma and catalyst. The study on the influence of temperature on the performance of the integrated plasma-Li/MgO system shows dominancy of plasma chemistry at the lower temperature (500°C), while contribution from the catalyst both in hexane activation and in enhancing olefin formation becomes significant at the higher temperature (600°C). At 500°C significant amount of acetylene...
