Neutron instrument BioRef arrived safely in Down Under
The SPATZ team of ANSTO was glad about the arrival of the former HZB neutron instrument BioRef. It will be set up until 2018 in Australia. photo: ANSTO.
As reported, the neutron instrument BioRef will be set up at the “Australian Centre for Neutron Scattering” of ANSTO. Approximately 257 components were safely packed in 43 wooden crates weighing just under 30 tonnes for the sea voyage from Hamburg to Port Botany, Australia. On 14 February the colleagues from ANSTO told us: the three shipping containers arrived safely after a two-month journey from Germany.
The ship transporting the packaged crates stopped at seven ports on the 45-day voyage which covered over 11,800 nautical miles.
ANSTO and HZB negotiated the transfer of the instrument from the BER-II Research Reactor at Helmholtz-Zentrum Berlin (HZB) and renewed a MOU for scientific collaboration with the renowned German research organisation in 2016. The instrument will be set up at the Australian Centre for Neutron Scattering (ACNS) until 2018. The new name is SPATZ, the German word for sparrow. It follows the tradition of the naming convention of other instruments at the Australian Centre for Neutron Scattering, which are named after Australian and other fauna. SPATZ will be available for user from Germany, too.

- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
- Solar cells on moon glass for a future base on the moonFuture settlements on the moon will need energy, which could be supplied by photovoltaics. However, launching material into space is expensive – transporting one kilogram to the moon costs one million euros. But there are also resources on the moon that can be used. A research team led by Dr. Felix Lang of the University of Potsdam and Dr. Stefan Linke of the Technical University of Berlin have now produced the required glass from ‘moon dust’ (regolith) and coated it with perovskite. This could save up to 99 percent of the weight needed to produce PV modules on the moon. The team tested the radiation tolerance of the solar cells at the proton accelerator of the HZB.
