Our chemistry didactics sub-project aims to scientifically support the public and scientific outreach of the Collaborative Research Centre/Transregio "CataLight" and to promote the transfer of findings into chemistry teaching and society. The photocatalytic production of hydrogen by sunlight is used to reconstruct specialised didactic results on the central questions and objectives of CataLight. The developed working materials and (model) experiments are then arranged and disseminated for schools, student laboratories, teacher training and public events.

Species extinction, climate and energy crisis, microplastics - chemistry is also facing new challenges. We want to discuss the current issues facing the chemical industry and how research and innovation can advance the transformation of society. What challenges are we facing? How can chemistry contribute to solving them? What goals has the chemical industry set itself? And what does this mean for the skills profile of chemistry students?

We look forward to a round table discussion with:

• Thomas Eberle, Head of Educational Partnerships and Strategic Projects Corporate Responsibilty at Merck KGaA, Darmstadt
• Lisa Groß, Fridays for Future, Berlin
• Michael Wark, Institute of Chemistry
• Verena Wolf, Expert Plant Authorisation, Biodiversity, Nature Conservation, Verband der Chemischen Industrie Landesverband Nord e.V. (VCI North), Laatzen

This game contains 18 quartet cards. Each card represents a specific refrigerant with its specific properties such as flammability or global warming potential. The purpose of the game is to learn about and explore the properties of certain refrigerants in order to gain a better insight into the world of refrigerants and the background to the use or prohibition of the substances depicted. The game was developed and designed by chemistry degree programme students as part of the module "Physical Chemistry 1: Thermodynamics and Kinetics". Have fun playing and learning!

Every year, the Institute of Chemistry and the Oldenburg chapter of the German Chemical Society (GDCh) honours students from the surrounding area with the Angelus Sala Prize for outstanding academic achievements in the subject of chemistry in the 10th grade.
In addition to the award ceremony, this event also provides all the information about studying chemistry today at the Carl von Ossietzky University of Oldenburg.

Photoelectron spectroscopy is used to obtain information on the chemical composition and bonding states near the surface. In the Physical Chemistry laboratory, together with Prof Dr Gunther Wittstock 's team, we get to the bottom of the question: Is this gold coin really made of gold?

Studying chemistry and then what?

Chemistry is everywhere in our environment, in our everyday lives and in many areas of our lives. Chemical processes can take on huge dimensions (just look at processes in factories or the growth of entire fields) or they take place on a scale that is more tangible for individual people: Internal combustion engines, there's a super amount of chemistry going on in the kitchen. But it can be even smaller. Digestive processes take place in all of us. Even smaller? Gladly: electricity from batteries or experiments with individual drops. And it can be even smaller, much smaller. Come along and enjoy a show for young and old about small and big chemistry!
(Organised by staff and students of the Chemistry Department under the direction of Dr Michael Peetz and Dr Alexander Weiz)

Black solar cells are used to generate electricity on many roofs in Oldenburg. But do solar cells always have to be black? No, other colours are also possible. Try out how simple solar cells can be produced with the help of fruit tea and a few other substances and test their function.

Waste biomass, e.g. green waste, liquid manure or fermentation residue from biogas plants, is available in abundance in Oldenburg and the surrounding area. We show how this can be used to produce biochar in simple plants. The biochars can potentially replace peat in plant substrates in the garden and thus limit the further destruction of ecologically valuable moorland, but they can also filter pollutants out of the air or water or serve as a carrier for catalysts.

Everyone knows about fish farming. But how can algae and other aquatic organisms also be utilised as raw materials in order to create added value both ecologically and economically? This is the focus of the "Bioeconomy on Marine Sites" innovation area. In particular, we are supporting creative start-up companies in a project to develop innovative, sustainably obtained products and bring them to market. Product developments will be presented at this stand and the benefits and risks of the marine (blue) bioeconomy can be discussed.

What do laboratories in which molecules are synthesised, i.e. produced, look like? What equipment is needed for this? This tour will show you what laboratories look like in which substances are produced, analysed and the samples are then tested for purity. On this tour, we will take a closer look at the process and visit three different laboratories where the individual steps are carried out.
Please note that for safety reasons, the laboratories of the limited-participation activities, especially in chemistry, may only be entered with closed shoes and long trousers (no leggings, preferably jeans or linen).

Lithium-based batteries and accumulators have become indispensable as energy storage devices. Members of Prof Dr Gunther Wittstock's working group have developed a new method for observing processes on the surface of electrodes during operation. The aim is to develop innovative battery components and at the same time develop techniques for testing these components. The work is part of the co-operation project "Alternative Materials and Components for Lithium-Oxygen Batteries" (AMaLiS) funded by the Federal Ministry of Education and Research (BMBF).
In this laboratory tour, Prof Wittstock and his colleagues provide an insight into the AMaLiS project and answer the question of how a federal government research project works.

"Green" hydrogen is being discussed as the "energy carrier of the future". In reality, hydrogen is a colourless gas; the colours often mentioned refer to how and from what hydrogen is produced.
The lecture will report on how hydrogen can be produced from water or waste biomass with the help of sustainably generated electricity, light, temperature or microorganisms. The storage of the hydrogen produced is also important for large-scale applications; the possibilities for this will also be discussed.
