What is ultraviolet radiation? What are X-rays used for? And what is radioactivity again? These questions are on the curriculum in physics lessons, but vivid experiments on these topics are rare. From 5 to 13 March 2020, pupils can conduct experiments on these topics in the HZB's school laboratory in Berlin-Adlershof. The public is invited to attend on 12 March.
The year 2020 is the focus of a double anniversary on the topic of X-rays. Nationwide, the 125th Discovery Day of X-rays and the 175th birthday of their discoverer and first Nobel Prize winner in physics, Wilhelm Conrad Röntgen, will be celebrated. To mark this occasion, the German Röntgen Museum in Remscheid (DRM) and the Reiss-Engelhorn Museums in Mannheim (rem) have developed the project "X-perimente - Making the Invisible Visible". The project is made possible by the Klaus Tschira Foundation in Heidelberg.
In the next few months, the X-ray mobile will be touring all over Germany. "It offers interactive experiments that are not offered at schools or in student laboratories in the Berlin-Brandenburg region. That's why the workshops on offer really are a unique opportunity," says Dr. Ulrike Witte, a member of the HZB school laboratory staff. Based on the fascination of the X-ray process, the experiments provide an overview of various techniques that can be used to make the inside of things visible: from infrared light to short-wave gamma rays and ultrasound.
Venue: Helmholtz-Zentrum Berlin, school laboratory, Magnusstraße 2, 12489 Berlin
Book workshops on the topics of X-rays and radiation
The campaign will take place from 5 to 13 March 2020 in the HZB school laboratory. Three workshops are offered per day (9 am, 11 am and 1 pm). They last 90 minutes and are free of charge. Booking is done by the teacher (max. 2 dates per school). The principle is: first come, first serve. Further information (GER) on the topics of the workshops can be found here.
Open for all: on 12 March from 3.30 to 5.30 pm
On 12 March 2020 the doors will be open to the public. You can experiment from 3.30 to 5.30 pm around the topics of X-rays, radioactivity and ultrasound.
The X-ray year 2020
The world of X-ray is full of surprising phenomena and fascinating images: This is what the X-ray year 2020 wants to draw attention to. On November 8, 1895, Wilhelm Conrad Röntgen discovered a new type of radiation. Since then they have enabled revolutionary advances in medicine, technology and society worldwide. X-rays penetrate substances and make layers visible that are otherwise invisible to the human eye: They are indispensable tools for studying solar cells, catalysts, viruses, genomes, tumors, old writings, machine parts, objects of art, celestial bodies and much more. The electron storage ring BESSY II, which is operated by HZB in Adlershof, provides highly brilliant X-ray light. Every year, it enables more than 1500 materials researchers, chemists, physicians, biologists and art historians from all over the world to gain unique insights into their samples.
- Georg Forster Research Fellow explores photocatalystsDr. Moses Alfred Oladele is working on photocatalysis for CO2 conversion in a joint project with the group of Dr. Matt Mayer, HZB, and Prof. Andreas Taubert at the University of Potsdam. The chemist from Redeemer's University in Ede, Nigeria, came to Berlin in the summer of 2024 with a Georg Forster Research Fellowship from the Alexander von Humboldt Foundation and will work at HZB for two years.
- Perovskite solar cells: New Young Investigator Group funded by BMBF at HZBIn the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.
- Dr. Michelle Browne receives Daimler and Benz Foundation FellowshipMichelle Browne heads a Helmholtz Young Investigators Group on electrocatalysis at HZB. She has now been selected as a fellow of the Daimler and Benz Foundation. She will receive 40,000 euros over the next two years and, in addition, access to an excellent research network.
