  • Sonnenlicht und Luft in flüssigen Treibstoff verwandeln? Ja, das geht! Ein Team der ETH Zürich hat die Technologie entwickelt: CO2 und Wasser werden der Luft entnommen, mittels Solarenergie aufgespalten und zur Herstellung von Kerosin oder Methanol verwendet. Noch sind die hergestellten Mengen gering, das Potenzial aber enorm.

  • Smart Dynamic Casting (SDC) is a continuous robotic slip-forming process that enables the prefabrication of material-optimised load-bearing concrete structures. In this automated process, a dynamic formwork, significantly smaller than the structure produced, is continuously moved at a velocity which allows concrete to be shaped during the critical phase that it changes from a soft to a hard material. As part of the dfab House at the EMPA premises in Dübendorf, CH, SDC was selected as one of five innovative construction techniques to demonstrate the construction of the future in digital fabrication. In this case SDC was used for the automated prefabrication of 15 bespoke material-optimized load-bearing façade mullions and additionally represents the first digital fabrication process world-wide which has unified reinforcement and concreting in a single robotic fabrication process. This extended abstract contextualizes SDC in the state of the art of digital concrete construction and highlights the challenges encountered when producing 15 individual mullions for the dfab House.

  • This software computes the magnetic hysteresis curves for an ensemble of Single Molecule Magnets. It has been used to reproduce data recorded on a sample consisting of Fe4 molecules deposited on a superconducting substrate of Pb(111) at temperatures lower than 1 Kelvin. Further details can be found in the article "Quantum dynamics of a single molecule magnet on superconducting Pb(111)" G. Serrano et al., Nat. Mater. (2020).

  • The Chair for the History of Technology at ETH Zurich has been using the search engine Opensenamticsearch as a shared search engine for historical sources, research literature and excerpts since 2018. In our presentation we will review the process that took several years and led to this implementation. We point out various surprises lurking in research projects that make digital research data and historical research interact in order to obtain meaningful data. We suggest that historians aim for research workflows and environments that are free for experiments, errors and exchange between researchers. Henrike Hoffmann, Moritz Mähr and Daniela Zetti are working with historical sources from various archives (Federal Archives Berne, University Archives Geneva, ETH Archive Zurich, PTT Archive Berne, CSCS Lugano). They deal with the issue on how the sources can be collected, analyzed, processed and made reusable. The sources are in German, French, Italian and English. They comprise documents that were written between 1960 and 2000. Most of the documents stem from public archives, some are publicly available, but a small number are within the protection period, i.e. accessibility is restricted. The research team is cooperating with technical, archival, legal and academic partners in Switzerland.
