Cu–Co-based model catalysts were prepared by a sophisticated alkali-free synthesis method and tested in the conversion of synthesis gas to higher alcohols. MoO3-coated alumina was used as the support, providing both high specific surface area and strongly interacting sites for the deposition of the active metals. A bulk Cu/Co ratio of ~2 was found to be most suitable in terms of activity and product distribution. Surface enrichment of Mo for all samples was observed by XPS, which significantly influenced the performance of the catalysts. Mo was found to be both a structural and a chemical promoter. Strong metal–support interactions were further achieved by modification of alumina with magnesia. With 12 wt% Mg incorporated, the catalysts showed 40% total oxygenate selectivity including 11% selectivity to ethanol.
An international, collaborative investigation is undertaken to evaluate the relative merits and limitations of various numerical methods and experimental measurement techniques, specifically for the analysis of flapping-wing propulsion. A finite aspect-ratio configuration is extensively investigated, both quantitatively and qualitatively, in a low-speed wind tunnel. Direct force measurements are made, as well as time-accurate and time-averaged laser Doppler velocimetry and unsteady flow visualization. The reduced frequency, mean angle of attack, aspect ratio and Reynolds number are varied in the experiments. The experiment is numerically simulated using flatplate theory, two and three-dimensional panel codes, and two and three-dimensional Euler and Navier- Stokes solvers. The ability of each of the methods to capture important aspects of the flow physics are evaluated through comparisons with each other and the experimental data. Additionally, the comparisons indicate areas where further research is needed. The collaborative effort provides a survey of available capabilities and provides a fixed set of flappingwing data for others to compare against.
A course called "Engineering Conferences" is presented that the authors have developed and installed as a mandatory part of the curriculum in Master programs for engineering students. The idea is to go beyond teaching the standards of academic writing and skills for working with scientific publications. By using a learner-centered approach, we get the students engaged in typical activities around an active attendance of a real conference. They write a paper complying with common academic standards, submit the paper and review submissions of their fellow students. Students also produce a poster and have to defend it in a poster session held publicly on campus. In this article, we present our rationale to develop the course and our results from the first semester teaching this course. This includes the presentation of useful resources for teaching and organizing scientific publishing as well as our reflected learning experience regarding the student's understanding of significance for scientific publishing.
Interkulturelle Innovation
(2014)
Innovationen können zu interkulturellen Irritationen führen. Diese Erfahrung musste ein bekannter deutscher Konsumgüterhersteller bei der Produktgestaltung eines Toilettensteins machen. Das Produkt sollte durch Farbe und Form sowohl Hygiene als auch Frische suggerieren. Doch die Farben wurden so gewählt, dass das Ergebnis unglücklicherweise wie die Flagge eines benachbarten Staates aussah, was zu wütenden Protesten einiger dortiger Kunden führte. Dies ist nur ein Beweis dafür, wie wichtig es ist, interkulturelle Aspekte im Innovationsprozess zu berücksichtigen.
In dem Beitrag beschreiben die Autoren einige der Widersprüche und Paradoxien im Zusammenhang mit Kreativität und schlagen die Nutzung des Wertequadrats nach Helwig zu deren Beschreibung vor. Die Autoren beschreiben die dynamische Balance, die zwischen Handeln und Geschehen-Lassen bei der individuellen Kreativität besteht. Außerdem gehen sie auf die Balance aus Führung durch Kontrolle und Führung durch Vertrauen ein, die für die Coporate Creativity erforderlich ist. Die Missachtung dieser dynamischen Balance bei der individuellen Kreativität kann zu einer "Culture of Looking Busy" führen, bei der rein kontemplative Tätigkeiten als unproduktiv angesehen werden. Bei der Corporate Creativity kann sie zu einer "Culture of Compulsive Control" führen, bei der Manager versuchen, die Kreativität ihrer Mitarbeiter zu kontrollieren anstatt sie zu fördern und zu unterstützen.
