At the 27th BESSY@HZB User Meeting, the Friends of HZB honoured the dissertation of Dr Enggar Pramanto Wibowo (Friedrich-Alexander University Erlangen-Nuremberg). The Innovation Award on Synchrotron Radiation 2025 went to Prof. Tim Salditt (Georg-August-University Göttingen) and Professors Danny D. Jonigk and Maximilian Ackermann (both, University Hospital of RWTH Aachen University).
The Ernst Eckhard Koch Prize 2025 honours outstanding doctoral theses in the field of synchrotron radiation research carried out at HZB or DESY. The award is named after the former scientific director of the BESSY GmbH, Ernst Eckhard Koch, who died in 1988.
This year, the Ernst Eckhard Koch Prize went to Dr Enggar Pramanto Wibowo from (Friedrich-Alexander University Erlangen-Nuremberg). In his dissertation, which was mainly carried out at HZB and at BESSY II, he deals with phosphorus chemistry in high-temperature PEM fuel cells. In doing so, he combines the further development of sophisticated in-situ/operando synchrotron methods with important contributions to the durability of fuel cells in the hydrogen economy.
The dissertation Elucidating the Complex Oxidation Behaviour of Phosphorus Impurities at the Pt|Aqueous H3PO3Interface in HT-PEMFCs by a Combination of X-ray Spectroscopies was proposed by Dr Raul Garcia-Diez and Prof. Dr Marcus Bär (Interface Design Department at HZB). The award committee emphasised: "An outstanding contribution to synchrotron radiation science, fully aligning with the spirit of this award. We especially wish to emphasise how Dr. Wibowo expanded the experimental capabilities of soft/tender X-ray synchrotron endstations to allow in situ/operando experiments under the harsh electrocatalytical conditions found in real-world fuel cells, while also expanding the understanding of phosphorous-focused X-ray spectroscopies."
Innovation Award on Synchrotron Radiation
The Innovation Award on Synchrotron Radiation 2025 went to Prof. Tim Salditt (Georg-August-University Göttingen) and Professors Danny D. Jonigk and Maximilian Ackermann (both University Hospital of RWTH Aachen University). The laudatory speech was given by Prof. Christian Schroer, Scientific Director of PETRA III (DESY).
They are being honoured for the development and application of histological tomography, a novel, high-resolution 3D X-ray imaging technique for tissues based on phase contrast. This method allows complex tissue architectures to be visualised non-destructively and in unprecedented detail.
The team has made decisive advances in this method and transferred it in a unique way to biomedical research, in particular to elucidate acute, subacute and late tissue damage in the lungs and heart in COVID-19.
The work exemplifies the bridge between modern X-ray optics, innovative reconstruction algorithms and clinically relevant questions. It opens up new diagnostic and pathophysiological insights into inflammatory, vascular and oncological diseases.
- Two winning entries from the HZB in the Helmholtz Imaging ContestA time resolved X-ray tomography by Paul H. Kamm, HZB, has won the second Jury prize and is the winner of the Helmholtz Imaging conference Partizipants Choice Award in this year’s competition. It shows a 3D snapshot of a laser welding process. Among the 20 most beautiful images is also a microscopy image of a solar cell by Yannic Kerkhoff and Daniel Abou Ras, HZB.
- Israel Ibukun Olaniyan receives the Helmholtz Doctoral Prize 2026At Helmholtz, more than 8,000 doctoral candidates conduct research. Eleven of them have now been honored for their original and outstanding work, among them Dr Israel Ibukun Olaniyan from the HZB. His doctoral thesis "Ferroelectricity at the nanoscale in epitaxial BaTiO3 on silicon" in the group of Professor Catherine Dubourdieu represents a step towards a new nanoelectronics based on topological defects, that can potentially help to create an energy efficient information technology.
- Only at BESSY II worldwide: IR nanoscopy at very long THz wavelengthsThe team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.
