Scientists from the European Synchrotron Radiation Facility (France) the Forschungszentrum Karlsruhe, the Technische Universität Berlin and the Helmholtz Zentrum Berlin (all Germany) were able to make fast processes inside opaque objects visible, by using white synchrotron radiation to perform hard X-ray radioscopy with high spatio-temporal resolution. The required imaging detector was constructed out of a standard indirect detector in combination with a Photron SA1 CMOS-based camera. Thus, it was possible to investigate pore coalescence and individual cell wall collapse in an expanding liquid metal foam: the rupture of a film and the subsequent merger of two neighbouring bubbles could be recorded with a time sampling rate of 40000 frames per second (25 micorseconds exposure time). The results as published in the Journal of Synchrotron Radiation (http://journals.iucr.org/s/issues/2009/03/00/kv5057/ – open access) allowed to determine that the pore stability in a liquid metal foam is driven by intertia and not the viscosity of the melt. This knowledge is crucial in order to adapt metal foaming process for industrial production.
3D Microscopy, taking place from July 12 -16, 2009 in Interlaken, Switzerland, is an international symposium focused on 3D imaging and spectroscopy in science. The objective of this symposium is to create a forum for researchers with different expertise and scientific interests to present their knowhow and the techniques they use to answer their scientific questions. Methods using three-dimensional imaging and spectroscopy to retrieve data in volume will be discussed, whether “light”, x-rays, electrons or near field probes are used. The conference contains 3 plenary talks and 9 sessions with invited and contributed talks and poster sessions.
Session topics are:
– High resolution TEM and AFM
– 3D CLSM and light microscopy
– 3D TEM and atom probe tomography/serial sectioning
– 3D correlative microscopy
– 3D X-ray microscopy and tomography
– 3D FIB/SEM or serial sectioning (with Denk-method) blockface tomography
– 3D image analysis and simulation
– 3D scanning probe microscopy
The European Microbeam Analysis Society (EMAS) will hold its 11th annual workshop on „Modern Developments and Applications in Microbeam Analysis“ from May 10-14, 2009 in Gdynia/Rumia, Gdansk, Poland. The main topics are electron probe microanalysis, micro- and nanoanalysis in the natural resources industry, fast energy-dispersive X-ray spectrometry, electron backscatter diffraction, and three-dimensional microanalysis. Time will also be devoted to problem orientated application of microbeam analysis techniques in fields such as catalysts, composites, glass, sensors, and in cultural heritage, environment, forensics, geology, mineralogy, metallurgy, microelectronics, surfaces and interfaces. The event will take place at the Hotel Spa Faltom, Gdynia/Rumia, Gdansk.
