Helmholtz Virtual Institute International Conference "Dynamic Pathways in Multidimensional Landscapes" 2016
We invite you to join the International Conference "Dynamic Pathways in Multidimensional Landscapes" which will take place in the heart of Berlin at the Magnus-Haus of the German Physical Society from September, 12th -16th, 2016. Now, the Online registration is open.
The conference is conducted by the Helmholtz Virtual Institute "Dynamic Pathways in Multidimensional Landscapes" where transient states of matter are captured in snapshots and electronic and structural dynamics are followed with Synchrotron and Free Electron Laser radiation.
At the conference we cross the boundaries of physics, chemistry and materials science and focus on unifying aspects of materials function. Since we also leave the regime of single photon interactions fundamental aspects of X-ray matter interaction are touched.
Online registration is open. Please submit abstracts of your oral or poster contributions. Out of these we will choose hot topic talks. Please take advantage of our limited accommodation contingency in Berlin and the participation at social events included in the conference fee.
For additional information and updates, please checkthe conference web portal. Other inquiries can be directed to the Conference Secretariat.
We’re looking forward to meeting you in Berlin.
- Superconducting TES array X-ray spectrometer goes into operation at BESSY IIEurope's first and only TES-spectrometer at a synchrotron source is now in operation at BESSY II, developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder CO, USA). The photon detection efficiency of the new instrument exceeds that of wavelength-dispersive X-ray emission spectrometers by a factor of 100 to 1000. It will be used to investigate the electronic properties of atomically thin layers, nanostructures and highly diluted atomic and molecular samples. The team is looking forward to receiving exciting research proposals from the user community.
- Magnon momentum microscopy: A new window into nanoscale spin-wavesAn international team lead by the Max Born Institute has developed a new type of momentum microscopy to image magnons — the quanta of collectively excited spins — directly in two-dimensional reciprocal space using soft X-rays. Measurements have taken place at BESSY II and PETRA III, first author ist the HZB physicist Steffen Wittrock. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and versatile platform for exploring nonlinear magnon interactions, which are promising for future computing schemes.
- BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteriesAlthough solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.
