8. April 2025: an industrial relations meeting (about the mapping of Baltics regional industry R&D interests)

A fruitful discussion about industry-academia cooperation, along with its challenges, took place in ZOOM with the Head of the Industrial Relations Office at MAX-IV. Dr. Magnus Larsson shared his experience in engaging industrial partners to collaborate with scientific research, providing practical information about existing platforms and facilities at MAX IV and more widely in Sweden. Valuable advice was provided how to organize cooperation with industry and what are important features for the mapping process.

31. March – 4. April, 2025: TR-SAXS experiment

The photoactive orange carotenoid protein (OCP) is a nanoscale high-light sensor and protects the photosynthetic apparatus of many cyanobacteria against photodamage. Upon illumination, OCP samples a number of conformational sustates to eventually adopt ist active state structure followed by a backtransformation to the dark-adapted state. However, many aspects of the latter “photocycle” still have to be deciphered. Teaming up with Martin Dulle and Andreas Stadler from FZJ in Jülich, Germany, we interfaced thesmall angle x-ray scattering (SAXS) instrument Ganesha with a setup for blue-light illumination to perform time-resolved SAXS experiment. This experiment will allow us to unravel the time scales of the individual photocycle processes as well as to determine the solution structures of intermediate photocycle states

September 2024 – February 2025: Test molecular dynamics simulation and proposal for Supercomputer Access

Starting from September 2024, we had the exciting opportunity to run test molecular dynamics simulations on the JURECA supercomputer at FZJ in Jülich, Germany, teaming up with Andreas Stadler, Jan Meinke, and Godehard Sutmann from FZJ to explore the dynamical behavior of the Orange Carotenoid Protein—a molecule that plays a key role in how cyanobacteria protect themselves from excess solar radiation.

Using cutting-edge molecular dynamics simulations, we looked at the protein in incredible detail, down to motions of individual parts at atomic scale. Our goal is to bring together computer simulations and real-world experiments, like neutron scattering.

This test run was essential in preparing a proposal for a full-scale, long-term project. We submitted the proposal in February 2024 to the Jülich Supercomputing Center, which provides some of the fastest computers in the world to help scientists tackle big, complex questions—like ours.

17. February 2025: Beamtime proposal writing training by MAX-IV Lab experts in ZOOM

Together with the MAX IV Lab a beamtime proposal writing training was organised in ZOOM. Dr. Andrey Shavorskiy carefully explained challenges in writing of successful proposal for synchrotron radiation research. Well selected exampled illustrated how to explain the research idea in a way that it will be selected. 18 participants, including early stage researchers, were attending from different Estonian Universities.

14. February 2025:  Series of seminars of computer simulations on modelling materials properties was launched
(3 ECTS for students at UTARTU).

After a preparation phase computer simulations on modelling materials properties seminar series was launched together by Institute of Physics, Institute of Chemistry and Institute of Technology  of Tartu University and with a significant contribution of our partner Imperial College UK.

28.-31. January 2025: sTARTUp Day 2025 – Estonia’s Top Startup Event and biggest in Baltics

sTARTUp Day is bringing together 3500+ startup-minded people to celebrate entrepreneurship in the smart city of Tartu.

The StartUp days held in Tartu, Estonia is one of the largest events in the Baltic countries, which has an international reach and annually brings together representatives of start-up companies, research organizations and investors to exchange experiences, ideas and profitable investments. The meetings were held with diferent entrepreneurs, technology developers and potential investors. EXANST was a part of UTartu technology exposition in its demo-space by introducing potential of experimental (MAX IV Lab, Sweden and FZ Jülich, Germany) and theoretical (Imperial College UK) reserach methods.  

13.-15. January 2025: 36th MAX IV Users meeting

The 36th User Meeting took place 13-15 January, with nearly 400 participants gathering at the Scandic Star hotel in Lund. It was an engaging event to network and listen to inspiring presentations for beamline users, researchers, collaborators, and students, as well as opportunities to speak with meeting sponsors and instrument vendors. Marta Berholts, Rainer Pärna and Marco Kirm communicated EXANST goals during poster sessioon and informal meetings during the conference. Also the EXANST progress was discussed with MAX IV reprsentatives.

27.11 – 02.12 2024: Training at SPECIES beamline

18-21 November 2024: Theory XFEL workshop 

The workshop in Marseille, France touched various topics related to predictive theories around XFEL interactions with matter. Our project presented novel modelling capabilities with an invited talk by Artur Tamm. This helps to promote developed tools to other groups as well as discover possible limitations and further improvement directions.

11.-17. November 2024: Experimental testing of the luminescence setup for studies of
ultrafast processes at FemtoMAX beamiline at MAX-IV Lab

During this week the characterization of the luminescence setup for studies of ultrafast processes at FemtoMAX beamiline was performed. The setup was developed together with FemtoMAX team as foreseen in the EXANST project plan. The expected time resolution 30 ps was achieved with MCP-PMT detector. It means that experiment is ready to accept new users from scintillation community and our Tartu team can start the planned research of ultrafast scintillators according to EXANST pilot projects.

13.-19. October 2024: 12th International Conference “Photosynthesis and Hydrogen Energy Research for Sustainability” in Istanbul, Turkey 

The conference is a well-established international forum for researchers and students engaged in research related to photosynthesis and (bio)hydrogen production with about 100 participants. The topics discussed include the fundamental processes of photosynthesis and the practical production of (bio)hydrogen. Special attention is payed to the structural organization of photosynthetic reaction centers, the structure and function of other photosystems, artificial photosynthesis, and hydrogen production mechanisms.

At this event, Prof. Jörg Pieper gave a talk about the application of neutron scattering methods under in-situ illumination to study structure and dynamics of photosystems, which is an essential part of the EXANST pilot research program. He also introduced the EXANST project as an important means for further method development.
