Within this thesis, both position-dependent charge transport measurements with a multi-tipscanning tunneling microscope (STM) are performed, and theoretical models for describingthese measured data are developed. Only a combination of both allows for actuallydisentangling multiple current transport channels present in parallel, in order to reveal thephysical properties of the investigated systems, i.e. [...]

Photoemission tomography (PT) is a combined experimental and theoretical techniqueapplied to molecule–metal interfaces which uses angle-resolved photoemissionspectroscopy over a wide angular range, while the photoelectron angular distributionsin reciprocal space (momentum maps, or called k-maps) are interpretedin terms of the molecular orbital structure of the initial state. This thesis uses PTto investigate various aspects of the interaction between π-conjugated organic molecularadsorbates and metal surfaces:PT was successfully used to identify the exact products of chemical reactionsat surfaces and their local bonding.

Soils act as both a source and sink of greenhouse gases (GHGs) and are widely considered to contribute toglobal warming. Soil N2O emissions originate from microbial nitrification and denitrification processes.Reducing conditions in soils alter the biogeochemical processes and result in large emissions of N2O andCH4.

Our brains are formed by networks of neurons and other cells which receive, filter, store and process information and produce actions. The morphology of the neurons changes through time as well as the connections between them. [...]

This Annual Report compiles last year´s activities of our institute, which have been achieved together withour cooperation partners and further collaborations at COSY, as well as experiments carried out at otherlaboratories in Germany and abroad (e.g. Gran Sasso, JLab) [...]

Advanced ceramics materials like yttrium oxide (Y2O3) are of high interest for criticalmanufacturing processes in the semiconductor industry due to their high chemicalstability in contact with fluorine based etching plasmas. However, until now Y2O3gets primarily applied as a functional coating deposited by thermal spray or aerosoldeposition technique due to complications associated with the manufacturing ofbulk ceramic components. [...]

All-solid-state batteries (ASSBs) are regarded as promising candidates for nextgenerationenergy storage systems due to several superior properties in comparisonto state-of-the-art batteries using liquid electrolytes. ASSBs have advantages withrespect to no-leaking electrolytes, wider temperature window, and potentiallyhigher volumetric energy density than those batteries using liquid electrolyte. [...]
