Expertise

The working group, of which Professor Adelhelm is head of, is engaged with the field of applied materials research. Where the main research focus lies on materials, which are suited for power storage in batteries. Therefore especially lithium-ion- and sodium-ion batteries, as well as alternative cell designs (metal-, sulphur- and all-solit-batteries) are being explored. However, the working groups goal has always been explorative research and the complete clarification of physico-chemical correlations.

Expertise

As part of their scientific activity Dr Markus Krutzik and the team members of the.quantum.chapter have acquired an extensive amount of expertise in developing tailored quantum sensors - from key technology to subsystem and system level. Quantum optical sensors and optical clocks are used in high-precision inertial navigation, gravimetry and gradiometry or for the synchronisation of networks. Hence, they are central for navigating GPS-free environments, for geophysics, the exploration of natural resources, the monitoring of climate change, and for addressing fundamental questions of modern physics. Central to their research are compact and robust setups for optical spectrocopy, absolute frequency references, and ultra-cold atom based inertial sensors. For this purpose, the team developed lasers and optical systems for generation and manipulation of light, as well as control software and data management platforms. Their setups are not only operated in laboratory research: They are also used as in field or even in space. In addition to development, testing and operation of atomic quantum sensors, Dr Krutzik and the team gained expert knowledge in all stages of mission and system design, ranging from mission architecture and identification of requirements to system integration and qualification, as well as development of control concepts and data analysis. In addition to Humboldt-Universität zu Berlin Dr Krutzik is also associated with Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik.

Scientific Services
  • Methods for the design, development and testing of compact, robust and tailored quantum sensors - from component to system level
  • Identification of critical technologies and construction of prototypes

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.
