Producing Graphene from Carbon Dioxide

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 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.

New Biocatalytic Material for “Green” Production of Value-added Chemicals

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.

Uniaxial pressure control of competing orders in a high-temperature superconductor

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.

“Scalable Rare Earth Ion Quantum Computing Nodes” (SQUARE) is funded by the European Commission with EUR three million.

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.
