With his talk on the properties of nanoparticles and how they can be measured more accurately at BESSY II, Dr. Raul Garcia Diez convinced the jury and was awarded the Dissertationspreis Adlershof 2017. Humboldt-Universität zu Berlin, IGAFA e. V. and the WISTA MANAGEMENT GmbH are the sponsors of this prize endowed with 3000 Euros. Garcia Diez completed his PhD in 2017 at PTB and TU Berlin and is now active as a post-doctoral researcher at HZB.
The use of nanoparticles in medicine is continuously growing, for example as platforms for drug-delivery or encapsulating imaging agents. In order to tailor nanoparticles for these applications, the functional properties of these particles need to be well understood.
In his thesis on "Characterization of Nanoparticles by Continuous Contrast Variation with Small-Angle X-ray Scattering" Raul Garcia Diez developed a method to study nanoparticles in a realistic environment with X-ray small-angle scattering in order to gain valuable information. The work was carried out with the HZB SAXS instrument, which is operated at the FCM beamline of the Physikalisch-Technische Bundesanstalt (PTB) in BESSY II under the cooperation between PTB and HZB.
With his work at PTB with Prof. Matthias Richter, he obtained his PhD title in May 2017 at the TU Berlin. Since then, Garcia Diez is a postdoctoral fellow with Prof. Marcus Bär at the HZB.

Peat as a sustainable precursor for fuel cell catalyst materials
Iron-nitrogen-carbon catalysts have the potential to replace the more expensive platinum catalysts currently used in fuel cells. This is shown by a study conducted by researchers from the Helmholtz-Zentrum Berlin (HZB), Physikalisch-Technische Bundesanstalt (PTB) and universities in Tartu and Tallinn, Estonia. At BESSY II, the team observed the formation of complex microstructures within various samples. They then analysed which structural parameters were particularly important for fostering the preferred electrochemical reactions. The raw material for such catalysts is well decomposed peat.

Helmholtz Investigator Group on magnons
Dr Hebatalla Elnaggar is setting up a new Helmholtz Investigator Group at HZB. At BESSY II, the materials scientist will investigate so-called magnons in magnetic perovskite thin films. The aim is to lay the foundations for future terahertz magnon technology: magnonic devices operating in the terahertz range could process data using a fraction of the energy required by the most advanced semiconductor devices, and at speeds up to a thousand times faster.

Susanne Nies appointed to EU advisory group on Green Deal
Dr. Susanne Nies heads the Green Deal Ukraina project at HZB, which aims to support the development of a sustainable energy system in Ukraine. The energy expert has now also been appointed to the European Commission's scientific advisory group to comment on regulatory burdens in connection with the net-zero target (DG GROW).
