The root system architecture (RSA) of a plant determinesthe plant’s ability to capture resources efficiently from the soil and directly linked to plantperformance. The development and distribution of plant’s root systems are determinedby the soil and surrounding environmental conditions. [...]

Soils contain large quantities of Fe, however, the Fe-solubility is very low. Plants have developedtwo efficient strategies to secure Fe uptake from soil under Fe-deficient conditions: (i) thesequential acidification-reduction-transport strategy (strategy I) and (ii) the chelation-basedstrategy (strategy II). [...]

We develop a simulator for quantum computers composed of superconducting transmon qubits. The simulation model supports an arbitrary number of transmons and resonators. [...]

Complex heterogeneities in the aquifers are critical and challenging to be detected and can have a significanteffect on subsurface flow and transport. Thereby, reliable prediction of groundwater flow and solutetransport is important for the protection of drinking water, and the remediation of contaminants. [...]

This thesis deals with a novel approach for analyzing and computing interior transmission eigenvalues of (piecewise) homogeneous media in two dimensions. It is based on approximating boundary data of respective eigenfunctions by the method of fundamental solutions. [...]

In nuclear fusion reactors there are extreme conditions for plasma facing components.Currently, pure tungsten (W) is used to withstand the enormous heat and particle fluxes,neutron irradiation and plasma erosion. However, a significant drawback is that Wis inherent brittle and thus can fail without warning. [...]

Power-to-Fuel technologies are indispensable for achieving a largely CO2-neutral energy supply in thefuture. The scientific contribution of this work is to answer the questions how technically mature,energy-intensive, and expensive different Power-to-Fuel concepts are compared to each other [...]

Neutrons are an essential tool for science and industry for probing the structure and dynamics ofmatter from the mesoscale to the picoscale and from seconds to femtoseconds. In Europe research,industry and society benet from a globally unique environment of various neutron sources withthe agship facilities ILL in Grenoble, France, and ESS in Lund, Sweden. [...]
