Fuel Cells in Switzerland ÂŒ a Brief Retrospective View FUEL CELL RESEARCH IN SWITZERLAND 824 CHIMIA 2004, 58, No. 12 Chimia 58 (2004) 824–825 © Schweizerische Chemische Gesellschaft ISSN 0009–4293 Fuel Cells in Switzerland – A Brief Retrospective View Günther G. Scherer* Abstract: Starting with the work of C.F. Schönbein, Switzerland has made important contributions to the history of fuel cell research. Starting with early developments in the first half of the 20th century, some highlights are men- tioned in this article. After a first wave of industrial interest in the 1960s, R&D in SOFC technology started about 1990 and is now on the road towards commercial introduction since about 2000. In parallel, polymer electrolyte fu- el cell research has advanced at research institutions, including work on components, stacks, and complete sys- tems.

    THE CANTON OF AARGAU: ECONOMY AND EMPLOYMENT The Canton of Aargau is situated in Switzerland’s strongest economic area. Some 340 000 people are employed here in around 40 000 companies. An above-average proportion of these workers are active in the field of research and development. In fact, this is more than twice the national average. Our economic, tax and financial policies make the Canton of Aargau an attractive place of business for international corporations as well as for small and medium-sized businesses. The innovative Robotec Solutions AG known as a leading enterprise in robot applications. Standard & Poor’s has awarded the Canton of Aargau the rating AA+. And it’s no wonder. After all, we have a low unemployment rate, a moderate taxation rate, a strong economy and a high standard of living. These factors appeal to many well-known companies operating here in a wide range of industries – including ABB, GE, Franke, Syngenta and Roche. Our media landscape is equally diverse. In addition to AZ Medien, the canton boasts numerous other well-positioned local media companies. THE CANTON OF AARGAU: LIFE AND LIVING SINA SINGER The Canton of Aargau is currently home to some 670 000 people. That makes us the fourth-largest canton in Switzerland. Aargau is an urban area, yet also modest in size. The Canton of Aargau is within reasonable distance of anywhere – whether by car or public transport. However, for those who prefer to stay and be part of the local scene, Aargau has well-established communities and a wealth of vibrant traditions.

  • Particle Accelerator Activities at the Paul Scherrer Institut
    PSI Bericht Nr. 17-07 December 2017 Particle Accelerator Activities at the Paul Scherrer Institut Terence GARVEY Paul Scherrer Institut, Villigen, Switzerland 5232 Division of Large Research Infrastructures Invited paper presented at Les Journées Accélérateurs de la Société Française de Physique, Roscoff, 3rd – 6th October, 2017. Resumé Les Activités Accélérateur à l’Institut Paul Scherrer. L'Institut Paul Scherrer exploite deux complexes d'accélérateurs en tant que ‘centre- serveurs’ pour une grande communauté de chercheurs. Il s'agit de l'Accélérateur de Protons à Haute Intensité (HIPA) et de la Source de Lumière Suisse (SLS). HIPA est un cyclotron à protons de 590 MeV. Il sert à produire des neutrons par spallation pour la recherche en physique de la matière condensée et à produire des muons et d'autres particules secondaires pour la recherche en magnétisme et en physique des particules. Le SLS est un anneau de stockage d’électrons de 2,4 GeV utilisé comme source de rayonnement synchrotron de 3ème génération fournissant des photons pour une large gamme de disciplines scientifiques. En plus de ces deux installations, l'Institut met progressivement en service un laser à électrons libres en rayons X (SwissFEL) qui fournira aux chercheurs des impulsions femto-seconde intenses à partir d’une ligne de rayons X ‘dur’ (ARAMIS) et de rayons X ‘mou’ (ATHOS). L'Institut exploite également un cyclotron supraconductrice à 250 MeV (COMET) aux fins de la thérapie par proton. Le centre de thérapie a récemment été équipé d'un troisième « gantry » rotatif qui est en cours de mise en service. Un « upgrade » du système de radiofréquence de HIPA et des projets pour "SLS-2" seront présentés.

  • Targeted Radiotherapeutics from 'Bench-To-Bedside'
    RadiochemistRy in switzeRland CHIMIA 2020, 74, No. 12 939 doi:10.2533/chimia.2020.939 Chimia 74 (2020) 939–945 © C. Müller, M. Béhé, S. Geistlich, N. P. van der Meulen, R. Schibli Targeted Radiotherapeutics from ‘Bench-to-Bedside’ Cristina Müllera, Martin Béhéa, Susanne Geistlicha, Nicholas P. van der Meulenab, and Roger Schibli*ac Abstract: The concept of targeted radionuclide therapy (TRT) is the accurate and efficient delivery of radiation to disseminated cancer lesions while minimizing damage to healthy tissue and organs. Critical aspects for success- ful development of novel radiopharmaceuticals for TRT are: i) the identification and characterization of suitable targets expressed on cancer cells; ii) the selection of chemical or biological molecules which exhibit high affin- ity and selectivity for the cancer cell-associated target; iii) the selection of a radionuclide with decay properties that suit the properties of the targeting molecule and the clinical purpose. The Center for Radiopharmaceutical Sciences (CRS) at the Paul Scherrer Institute in Switzerland is privileged to be situated close to unique infrastruc- ture for radionuclide production (high energy accelerators and a neutron source) and access to C/B-type labora- tories including preclinical, nuclear imaging equipment and Swissmedic-certified laboratories for the preparation of drug samples for human use. These favorable circumstances allow production of non-standard radionuclides, exploring their biochemical and pharmacological features and effects for tumor therapy and diagnosis, while investigating and characterizing new targeting structures and optimizing these aspects for translational research on radiopharmaceuticals. In close collaboration with various clinical partners in Switzerland, the most promising candidates are translated to clinics for ‘first-in-human’ studies.

  • Research at the Paul Scherrer Institut
    390 FR9807042 Research at the Paul Scherrer Institut H. K. Walter Paul Scherrer Institut, PSI - West, CH- 5232 ViUigen, Switzerland Abstract The Paul Scherrer Institut (PSI) is a multidisciplinary research institute for natural sciences and technology. In national and international collaboration with universities, other research institutes and industry, PSI is active in elementary particle physics, life sciences, solid-state physics, material sciences, nuclear and non-nuclear energy research, and energy-related ecology. PSI's priorities lie in research fields which are relevant to sustainable development, serve educational needs and are beyond the possibilities of a single university department. PSI develops and operates complex research installations open to a national and international scientific community. With the upgrade of the 590 MeV Ring accelerator PSI disposes of the world's most powerful cyclotron, allowing to operate high intensity secondary pion and muon beams, a neutron spallation source and various applications in medicine and materials research. A short review on research at PSI is presented, with special concentration on particle physics experiments.

  • The Crystallographic Revolution
    8 CHIMIA 2014, 68, Nr. 1/2 Crystallography, past, present, Future doi:10.2533/chimia.2014.8 Chimia 68 (2014) 8–13 © Schweizerische Chemische Gesellschaft ‘Seeing’ Atoms: The Crystallographic Revolution Dieter Schwarzenbach* Abstract: Laue’s experiment in 1912 of the diffraction of X-rays by crystals led to one of the most influential discoveries in the history of science: the first determinations of crystal structures, NaCl and diamond in particular, by W. L. Bragg in 1913. For the first time, the visualisation of the structure of matter at the atomic level became possible. X-ray diffraction provided a sort of microscope with atomic resolution, atoms became observable physical objects and their relative positions in space could be seen. All branches of science concerned with matter, solid-state physics, chemistry, materials science, mineralogy and biology, could now be firmly anchored on the spatial arrangement of atoms. During the ensuing 100 years, structure determination by diffraction methods has matured into an indispensable method of chemical analysis. We trace the history of the development of ‘small-structure’ crystallography (excepting macromolecular structures) in Switzerland. Among the pioneers figure Peter Debye and Paul Scherrer with powder diffraction, and Paul Niggli and his Zurich School with space group symmetry and geometrical crystallography. Diffraction methods were applied early on by chemists at the Universities of Bern and Geneva. By the 1970s, X-ray crystallography was firmly established at most Swiss Universities, directed by full professors. Today, chemical analysis by structure determination is the task of service laboratories. However, the demand of diffraction methods to solve problems in all disciplines of science is still increasing and powerful radiation sources and detectors are being developed in Switzerland and worldwide.

This further emphasized the need for material on physics and its history intended for the generally educated public. One disquieting note, which lessened the euphoria, was the fact that in all of the programs, articles, and lists, there were very few other mentions of science. Quantum mechanics, the discovery of the double-helical structure of DNA, the polio vaccines of Salk and Sabin, and countless other significant achievements in science, take your pick, seemed conspicuously absent.

  • 50 Years of Radiation Protection and Nuclear Power in Switzerland: a Brief History
    Atoms for Peace: An International Journal, Vol. 1, Nos. 2/3, 2006 239 50 years of radiation protection and nuclear power in Switzerland: a brief history Hansruedi VoÈlkle Section for Environmental Radioactivity, Division for Radiation Protection, Swiss Federal Office of Public Health, c/o Physics Department, University of Fribourg, Chemin du Muse e3, CH-1700 Fribourg, Switzerland E-mail: [email protected] Abstract: This article presents a short history of research in nuclear physics as well as of 50 years of nuclear power and radiation protection in Switzerland. After the International Conference `Atoms for Peace' held in 1955 in Geneva the first research reactor was installed in Switzerland. A national environmental radioactivity monitoring programme was started in 1956. Today some 40% of the electricity is produced by nuclear power. In 1986, the southern part of Switzerland was most burdened by radioactive fallout from the Chernobyl Accident. Fortunately, the integral average radiation doses to the population remained below 0.5 milli-Sievert. As in other western countries there was a vigorous debate in Switzerland in the 1980s and 1990s about nuclear power, nuclear safety and the safe storage of radioactive waste. Keywords: environmental radioactivity; nuclear physics; nuclear power; radiation protection. Reference to this paper should be made as follows: VoÈ lkle, H. (2006) `50 years of radiation protection and nuclear power in Switzerland: a brief history', Atoms for Peace: An International Journal, Vol. 1, Nos. 2/3, pp.239±244. Biographical notes: Hansruedi VoÈ lkle gained his Diploma in Physics from Fribourg University in 1974. Since 1973, he has been working for the Environmental Radioactivity Section in Fribourg of the Swiss Federal Office of Public Health, from 1987 to the end of 2005, as head of the section.
