7. Partially hydrophobized catalyst particles for aqueous nitrite hydrogenation - Franch, Cristina; Lammertink, Rob G.H.; Lefferts, Leon
The aim of this work is to synthesize catalysts support particles that are partly hydrophobic and partly hydrophilic, with the ultimate goal to manipulate the performance of Pd supported catalysts on these supports for hydrogenation of nitrite in water. Partly hydrophobic alumina supports were successfully prepared via physically mixing of hydrophobic α-alumina and hydrophilic γ-alumina, and via varying the amount of perfluorinated-octyltrichlorosilane (FOTS) on pure γ-alumina. The results from elemental analysis, SEM-EDX, XRD and contact angle measurements confirmed that the materials indeed contained hydrophobic and hydrophilic domains. Pd catalysts on supports produced via the mixing method resulted in a slightly...

8. Scenarios to explore the futures of the emerging technology of organic and large area electronics - Parandian, Alireza; Rip, Arie
Emerging technologies pose challenges for futures research because of their uncertainties combined with promises. Actors are anticipating and acting strategically. Sociotechnical scenarios building on endogenous futures support and enlighten actors. Such scenarios contribute to “strategic intelligence” about the technologies and their embedding in society. Organic and large area electronics promise to substitute silicon-based technologies, but firms and potential users are reluctant to invest. Ways to break through this “waiting game” are the starting point for scenarios that were developed as in an input in strategy articulation workshops with different stakeholders and third parties. The scenarios are offered as they were...

9. Pervasive Normativity and Emerging Technologies - Rip, Arie
Normativity is everywhere. It is taken up in ethics, but also in law and political theory, and more implicitly in economics and sociology. And there is the de facto normativity of master narratives and imaginaries, like the modernist narrative of progress—in particular progress through science. There is also, underlying many normative issues, the fundamental challenge (die ärgerliche Tatsache) of social order, as a value in its own right, and thus to be conserved, and/or as a constraint that needs to be opened up. This essential ambivalence of social order feeds into the discourse about innovation, which can be embraced as...

10. Umbrella Terms as Mediators in the Governance of emerging Science and Technology - Rip, Arie; Voß, Jan-Peter
Umbrella terms like ‘nanotechnology’ and ‘sustainability research’ have emerged as part of the new regime of Strategic Science. As mediators between science and society they have a dual role. Their overall promise allows resources to be mobilised for new fields which can then be productive in their own right. At the same time, however, they also put pressure on these fields to take relevance considerations into account. The process of emergence and stabilisation of umbrella terms is outlined and traced in detail in the cases of nanotechnology and sustainability research. What we see is interesting de facto governance of science,...

11. Indications of Socio-Economic Impacts of Nanotechnologies: The Approach of Impact Pathways - Robinson, D.K.R.; Rip, A.

12. A UHF 4th-order band-pass filter based on contour-mode PZT-on-silicon resonators - Yagubizade, Hadi; Darvishi, Milad; Elwenspoek, Miko C.; Tas, Niels R.
A UHF 4th-order band-pass filter (BPF) based on the subtraction of two 2nd-order contour-mode resonators with slightly different resonance frequencies is presented. The resonators consists of a 1 μm pulsed-laser deposited (PLD) lead zirconate titanate (PZT) thin-film on top of a 3 μm silicon (PZT-on-Si). The resonators are actuated in-phase and their outputs are subtracted. Utilizing this technique, the outputs of the resonators are added up constructively while the feed-through signals are eliminated. The BPF presented a bandwidth of approximately 28.6 MHz and more than 30 dB stopband rejection at around 700 MHz.
