Der Kanton Aargau unterstützt das Technologietransferzentrum Anaxam in Villigen für die Dauer von vier Jahren mit insgesamt 2,4 Millionen Franken. Der Grosse Rat hat am Dienstag in Spreitenbach den entsprechenden Kredit mit 124 zu 3 Stimmen bewilligt.
The Dikic group at the Goethe University in Frankfurt am Main, Germany has published the first results following the opening of the "PRIORITY COVID-19 Call” at SLS.
Ultra-fast operando X-ray diffraction experiments reveal the temporal evolution of low and high temperature phases and the formation of residual stresses during laser 3D printing of a Ti-6Al-4V alloy. The profound influence of the length of the laser-scanning vector on the evolving microstructure is revealed and elucidated.
LaTiOxNy oxynitride thin films are employed to study the surface modifications at the solid- liquid interface that occur during photoelectrocatalytic water splitting. Neutron reflectometry and grazing incidence x-ray absorption spectroscopy were utilised to distinguish between the surface and bulk signals, with a surface sensitivity of 3 nm.
On January 30th, 2020, the WHO declared the recent outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of international concern. It declared that there is an urgent need to improve our understanding of the newly identified virus and its possible future evolution as well as to contain the spread; to develop precise diagnostics and treatment, and to improve the public health response and patient care.
Mit einer neu entwickelten Untersuchungsmethode konnten Forschende die magnetische Struktur im Inneren eines Materials mit Nanometer-Auflösung abbilden. Ihnen gelang ein kurzer «Film» aus sieben Bildern, der erstmalig in 3-D zeigt, wie sich winzige Wirbel der Magnetisierung tief im Inneren eines Materials verändern.
3D imaging using synchrotron radiation is a widely used tool that allows access to the inner structure of complex objects. An international and interdisciplinary consortium of scientists from the Swiss Light Source (PolLux and cSAXs), the Friedrich-Alexander-Universität Erlangen-Nürnberg, and the University of Cambridge developed the new 3D imaging technique of Soft X-ray Laminography (SoXL). SoXL allows for the investigation of thin and extended samples while taking advantage of the characteristic absorption contrast mechanisms in the soft X-ray range, providing 3D information with nm spatial resolution.
Researchers of the Paul Scherrer Institut have previously generated 3-D images of a commercially available computer chip. This was achieved using a high-resolution tomography method. Now they extended their imaging approach to a so-called laminography geometry to remove the requirement of preparing isolated samples, also enabling imaging at various magnification. For ptychographic X-ray laminography (PyXL) a new instrument was developed and built, and new data reconstruction algorithms were implemented to align the projections and reconstruct a 3D dataset. The new capabilities were demonstrated by imaging a 16 nm FinFET integrated circuit at 18.9 nm 3D resolution at the Swiss Light Source. The results are reported in the latest edition of the journal Nature Electronics. The imaging technique is not limited to integrated circuits, but can be used for high-resolution 3D imaging of flat extended samples. Thus the researchers start now to exploit other areas of science ranging from biology to magnetism.
