A look inside chemical reactions

German-Brazilian workshop at Kiel University for the targeted production of nanomaterials

Without new materials with special luminescent and magnetic properties or a particular electrical conductivity, many of our modern technologies would not work. Thanks to specific structures on the nano scale, they provide the necessary lighting in LEDs, laptop displays or mobile phones, increase energy storage density in batteries, or enable more sensitive sensors.

Which mechanisms occur during the formation of these materials, and how their manufacturing processes can be further improved, are being discussed from yesterday (31 July) until Thursday (2 August) by around 40 scientists from Brazil and the Germany at Kiel University (CAU).

Researchers from the fields of chemistry, physics and engineering sciences are participating in the interdisciplinary conference. In addition to scientific exchanges, the aim is particularly also to establish international research cooperation. An important part of this is the involvement of early career researchers.

"Our technical devices are constantly becoming smaller and more powerful. For this we need the right materials," said Dr Huayna Terraschke from the Institute of Inorganic Chemistry. The development of new materials is the subject of the German-Brazilian workshop, which the engineer organised together with institute director Professor Wolfgang Bensch.

"However, what happens on a chemical level during the synthesis of such materials has not yet been clarified for the majority of materials. If we learn more about the fundamental processes and mechanisms, we could for example manufacture more efficient batteries and storage media in future," said Bensch. If scientists better understand the structural development of materials at the atomic level, they could specifically modify the properties of materials in future.

The three-day workshop in Kiel is dedicated to the mechanisms of such chemical reactions, from the perspective of fundamental research. The special feature of the event is the combination of specialist expertise from Brazil and Germany: while the scientists from the Brazilian state of São Paulo can contribute their expertise in the development of new functional materials, the researchers from Germany have many years of experience in the "in-situ" analysis of the formation of such materials.

These investigations occur while a chemical reaction is taking place, and allow the individual steps up to the final product to be monitored "live", and thereby to decipher the mechanisms. This is possible, for example, by use of the intense X-rays at the Deutsches Elektronen-Synchrotron (DESY). "We are delighted to welcome colleagues from Brazil and all over Germany here in Kiel.

With this workshop, we want to lay the foundation for intensive bilateral cooperation, in which the different areas of scientific expertise will certainly complement each other very effectively,” said Bensch to welcome the participants.

After the opening lecture by Professor Hermi Felinto de Brito from the University of São Paulo, an expert in the development of luminescent materials for LEDs and energy-saving lights, there will be 26 more specialist presentations and a poster session. From Kiel University, Professor Wolfgang Bensch will present his research on new materials for batteries, Professor Norbert Stock new porous materials, and Dr Huayna Terraschke a new method for in-situ characterisation of chemical reactions.

The third day of the workshop will focus on the promotion of early career researchers: young scientists from Germany and Brazil will present their projects, and thereby get the opportunity to discuss their research with leading experts on an international level. "In order to sustainably strengthen this international cooperation, we want to integrate young scientists at an early stage," emphasised Terraschke.

In conclusion, the participants will visit DESY in Hamburg, to see some of the previously-described methods of analysis in action on site. The close cooperation with one of the world's leading accelerator centres is a key success factor for Kiel’s long-term experience in the study of chemical reactions in real time.

The conference is funded by the German Research Foundation (DFG) and the São Paulo Research Foundation (FAPESP).

Details, which are only a millionth of a millimetre in size: This is what the priority research area "Kiel Nano, Surface and Interface Science – KiNSIS" at Kiel University has been working on. In the nano-cosmos, different laws prevail than in the macroscopic world - those of quantum physics. Through intensive, interdisciplinary cooperation between physics, chemistry science, engineering and life sciences, the research area aims to understand the systems in this dimension and to implement the findings in an application-oriented manner. Molecular machines, innovative sensors, bionic materials, quantum computers, advanced therapies and much more could be the result. More information at http://www.kinsis.uni-kiel.de

Im Focus: Hamburg and Kiel researchers observe spontaneous occurrence of skyrmions in atomically thin cobalt films

Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films even without an external magnetic field. They report on their discovery in the journal Nature Communications.

The existence of magnetic skyrmions as particle-like objects was predicted 30 years ago by theoretical physicists, but could only be proven experimentally in...

Im Focus: Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine.

Work performed by Professor John Goold's QuSys group in Trinity's School of Physics describes the science behind this tiny motor.

Im Focus: Quantum computers to become portable

Together with the University of Innsbruck, the ETH Zurich and Interactive Fully Electrical Vehicles SRL, Infineon Austria is researching specific questions on the commercial use of quantum computers. With new innovations in design and manufacturing, the partners from universities and industry want to develop affordable components for quantum computers.

Ion traps have proven to be a very successful technology for the control and manipulation of quantum particles. Today, they form the heart of the first...

Im Focus: Towards an 'orrery' for quantum gauge theory

Experimental progress towards engineering quantized gauge fields coupled to ultracold matter promises a versatile platform to tackle problems ranging from condensed-matter to high-energy physics

Im Focus: A miniature stretchable pump for the next generation of soft robots

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.

Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
