Expertise

Professor Bojdys research focuses on the design of covalent organic polymers with applications as organic transistor devices and on light-reactive polymers (e.g., Nat. Commun. 2019. DOI: 10.1038/s41467-019-11264-z). He and his team cooperate with established battery and coating companies and with a Berlin SME.

Recently, Professor Bojdys and his team successfully licensed their patent for high capacitance anodes (WO2020DE100294, DE102019110450), built from their materials. They aim to further develop their technology with industrial partners within the newly established European Innovation Council (EIC).

Since 2018, Professor Bojdys has been a member of the "Young Scientists" at the World Economic Forum (WEF) and further serves on their advisory board since 2019.

Expertise

Prof. Schröder’s and his team’s research is focused on the non-destructive method of x-ray powder diffractometry to identify and characterise minerals. Subsequently, the powder samples can be analysed by other methods. The method of x-ray powder diffractometry and its content is closely related to the field of mineralogy and crystallography. Therefore, the method is used in materials research and building materials science. The team is working towards an implementation of the method in continuing and adult education, teaching and learning approaches. Materials suitable for x-ray powder diffractometry: Building materials, concrete, mortar, cement, fine and heavy ceramics, rocks, ores, sediments, ash, dust, filter and combustion residues. Potential fields of applications are: Clay mineralogical investigations (soil science - agriculture), archaeometric investigations (ancient colours and paints, bronze patina and archaeological ceramics), identification of unknown crystalline substances (fingerprinting), identification of crystalline phases, qualitative and semi-quantitative analyses of mixtures, isomorphisms, polymorphisms, determination of amorphous and crystalline states as well as state of crystallisation and particle sizes. The analysis is conducted with powder on a matrix < 32 µm and with texture specimen on a matrix < 2 µm.

Expertise

With his Computer Engineering research group, Prof. Scheuermann develops technologies for application-specific communication and computer systems that are efficient, secure, and reliable. The topics range from tailored communication protocols and application-specific digital circuits all the way to different aspects of online anonymity and privacy-preserving technologies. For instance, Prof. Scheuermann aims to interconnect automobiles to make best possible use of the available road network resources. Furthermore, he develops specialised circuitry for firewalls, so that within nanoseconds the firewall can decide what communication should be permitted. The research team models flow control and congestion control mechanisms for Internet anonymity systems, which for example allow political activists in totalitarian regimes to bypass Internet censorship. They design privacy compliant data collection algorithms, which grant detailed Internet traffic statistics without revealing information about individual users. His team’s expertise encompasses the set-up of wireless communication in between manufacturing machines in factories, so as to optimize the production process. In the field of warehouse logistics, Prof. Scheuermann combines measurements from various types of sensors to allow for a more accurate positioning of goods. In all fields of operation, tailored solutions for communication protocols and circuitry are necessary. The challenges are rooted in the particular application area: for instance, very fast or particularly reliable communication may be needed. Or data exchange is limited due to inherent technical limitations, yet the respective application must function reliably. It could be the case that IT security requirements need to be taken into account in new application fields where standard solutions fail. There may be a trade-off between data protection requirements or user privacy concerns, and communication requirements for data transmission. In all mentioned examples, it is necessary to look beyond common solution strategies and to keep the whole picture in mind. This systems perspective characterises the Computer Engineering group and its projects.

Expertise

Prof. Kuemmerle’s team strives to better understand how land use change affects the environment and society. This includes assessments of spatial patterns and the underlying drivers of, for example, tropical deforestation, agricultural abandonment, or intensification of farming. Furthermore, the team studies how changes in land use affect the ecosystem services (e.g. food production or carbon storage) and biodiversity. As one focus the work group analyses trade-offs between use of resources and nature conservation, as well as how such trade-offs could be mitigated. The group also seeks to generate insights and records of high practical value for land use and nature conservation planning, and to assess the effectiveness of nature conservation measures. Prof. Kuemmerle’s regional focus is on Europe, the former Soviet Union and Latin America.

Prof. Dobbek analyses the biochemical principles of bacterial growth on substrates, i.e. carbon dioxide, carbon monoxide as well as aromatic compounds, which also are pollutants. The main focus lies on the functional and structural investigation of metalliferous enzymes that transform unreactive molecules in oxygen free conditions and thus enable bacteria to grow in a seemingly hostile environment. Developing new (biological) catalysts capable of energy-efficiently transforming carbon dioxide and monoxide is Prof. Dobbek’s goal. Moreover these catalysts are designed to generate new enzymes for the biological decomposition of substances damaging to humans and the environment.

Expertise

Dr Schwalbe and his group investigate the activation of small molecules at metal complexes. The main focus is not only research on electrocatalytic but also photocatalytic processes. With the help of renewable energy sources, and preferably the direct use of sunlight, formally unreactive molecules such as CO2, O2 or H2O should be transformed efficiently into valuable compounds. The syntheses of metal complexes is in fact in the foreground, but following the comprehensive chemical, structural and physical characterisation of the newly designed compounds their catalytic properties are especially explored. At the moment Dr Schwalbe is working in particular on the light-driven reduction of CO2 to CO or HCO2H, and in doing so he examines the influence of different reaction parameters (e.g. water content of the solvent, used photosensitizer or excitation wavelength) on the product selectivity. Furthermore the development of catalytic systems for homogeneous as well as heterogeneous water oxidation or oxygen reduction is pursued. For this, Dr Schwalbe considers on the one hand the fixation of molecular systems on electrode surfaces, and on the other hand the direct integration of monomeric building blocks in polymer networks. Within his research efforts he creates promising catalysts (and dyes) that can later be applied in e.g. fuel cells or photo-reactors.

Expertise

The team of Christoph Schneider works on the impacts of climate and climate change in the field of urban climates and in the field of cryospheric sciences (anything related to snow and ice). His expertise comprises the downscaling of meteorological respectively climatological data for applications in high spatial resolution, for example for urban planning and construction schemes and also for the analysis of potential impacts of climate change on the level of city quarters and cities. Furthermore, such numerical and empirical-statistical procedures are applied to the projection of future water resources in glaciated catchments in high alpine environments worldwide. This also leads to applications regarding the future state of snow covers in mountain ranges which is especially important for questions of future prospects of snow sport tourism. In both fields of applications, the urban climatology and the cryospheric research, measurement strategies and data acquisition of relevant atmospheric variables for the projects are used besides theoretical modelling approaches and downscaling as outlined above.
