Carbon dioxide is not only a greenhouse gas in the atmosphere leading to global-warming effect, it can also be a useful raw material for chemical reactions. A working group at KIT is using carbon dioxide as a raw material to produce graphene, a technological material which is currently the subject of intense study. The work on this unusual application has been reported in the ChemSusChem journal (DOI: 10.1002/cssc.201901404).
The search for new active substances, their production, characterization, and screening for biological effectiveness are very complex and costly. Scientists of KIT have now succeeded in combining these processes on a chip and, hence, facilitating and accelerating the procedures to produce promising substances. The results are published in Nature Communications (DOI 10.1038/s41467-019-10685-0).
On Tuesday, June 4, 2019 at 6:30 PM, scientists from the KIT Materials Center will present their research on new technologies in the Karlsruhe City Hall.

The First Prize of the BMBF Validation Award Goes to the ARES “Air-retaining Surfaces” Project on Bionic Ship Coatings that Reduce Friction between Ship Walls and Water. Friction, corrosion, and biofilms are three major problems in shipping. The research project ARES – a collaboration project of KIT and the universities of Bonn and Rostock – studies new types of ship coatings that permanently retain an air layer under water and, thus, help considerably reduce the three problems.

Professor Wolfgang Wernsdorfer of KIT receives the Gottfried Wilhelm Leibniz Prize 2019 of the German Research Foundation (DFG). Germany’s highest science prize endowed with EUR 2.5 million honors the experimental physicist for his research into electronics, spin physics, and quantum computing.
Industry consumes large quantities of crude oil to produce basic substances for drugs, cosmetics, plastics, or food. However, these processes consume a lot of energy and produce waste. Biological processes with enzymes are far more sustainable. The protein molecules can catalyze various chemical reactions without auxiliary materials or solvents being required. But they are expensive and, hence, have been economically unattractive so far. Researchers of KIT have now developed a new biomaterial that considerably facilitates the use of enzymes. The results are presented in the journal Angewandte Chemie, Oct. 2018.
High-temperature superconductors can transport electrical energy without resistance. Researchers at KIT have carried out high-resolution inelastic x-ray scattering and have found that high uniaxial pressure induces a long-range charge order competing with superconductivity. Their study opens up new insights into the behavior of correlated electrons. The researchers report on it in the journal Science, Nov. 2018.
Polymer pelts made of the finest of fibers are suitable for many different applications, from coatings that adhere well and are easy to remove to highly sensitive biological detectors. Researchers at KIT together with scientists in the United States have now developed a cost-effective process to allow customized polymer nanofibers to grow on a solid substrate through vapor deposition of a liquid crystal layer with reactive molecules. The researchers report on their innovative method in the journal Science, Nov. 2018.
Quantum computers can execute many computation steps in parallel. This will accelerate processing of large data volumes. The microstructure of certain materials and elements of the quantum bits, however, is of crucial importance. Researchers KIT study materials for such multi-functional quantum bits.
“A promising approach to the next generation of quantum computers is based on materials, single systems of which are not larger than an atom and the quantum properties of which can be accessed and controlled optically,” says Professor David Hunger of KIT’s Physikalisches Institut, who coordinates the SQUARE project.

The new photoresists are presented in the journal Nature Communications, July 2018
KIT scientists, together with experts for dental implants, have now developed a nanostructured surface to accelerate wound healing after implantation and to better protect it against the attack of bacteria.
Innovative Method for Steel Strip Drying – The KIT-Institute of Combustion Technology of the Engler-Bunte Institute is coordinating the research project in the EU’s Horizon 2020. Thanks to a new furnace design, energy efficiency in industrial steel strip drying can be significantly increased and the size of the facility drastically reduced. Using the planned process, investment and production costs can be cut by at least 40 percent. This is achieved through the use of infrared radiant burner technology.
Pure quartz glass is highly transparent and resistant to thermal, physical, and chemical impacts. These are optimum prerequi-sites for use in optics, data technology or medical engineering. For efficient, high-quality machining, however, adequate pro-cesses are lacking. Scientists of KIT have developed a forming technology to structure quartz glass like a polymer. This innovation is reported in the journal Advanced Materials, 2018

Solar cells with efficiencies above 20% and produced at low costs – perovskites make this possible. Now, KIT-researchers have gained fundamental insight into the function of perovskite solar cells. They found that bound states of electron-hole pairs can form during the absorption of light. Still, these pairs can be separated easily for current to flow. In addition, they enhance absorption.
Researchers of KIT have how developed a new solution for the coupling of optical microchips to each other or to optical fibers. They use tiny beam-shaping elements that are printed directly onto the facets of optical components by a high-precision 3D printing process. These elements can be produced with nearly any three-dimensional shape and enable low-loss coupling of various optical components with a high positioning tolerance.
