Improving stationary and mobile cosmic ray neutron soil moisture measurements Assessment of the cosmic ray neutron uncertainty and the potential of the thermal neutron signal
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 578, xxiii, 137 (2022)2022 = Dissertation, Univ. Bonn, 2022
Soil moisture has a major influence on the partitioning between infiltration and runoff, and thus affects groundwater recharge, floodings, and the susceptibility of hillslopes to landslides. In addition, soil moisture can influence weather and climate, and the availability of water for plant growth directly affects agricultural productivity and food supply. [...]

Towards 3D crosshole GPR full-waveform inversion
Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 574, viii, 122 (2022)2022 = Dissertation, RWTH Aachen University, 2022
High-resolution imaging of the subsurface improves our understanding of thesubsurface flow and solute transportation that can directly help us protectgroundwater resources and remediate contaminated sites. The ground penetratingradar (GPR) is a useful non/minimal invasive method that consists of a transmitter(Tx) unit that emits electromagnetic (EM) waves and a receiver (Rx) that measuresthe arriving electromagnetic waves and can provide high-resolution tomograms of thesubsurface properties.In specific, the crosshole GPR setup in which two-neighbouring boreholes are placedin the earth can provide much more in-depth access to the target area [...]

Ecological sanitation via thermophilic co-composting of humanure and biochar as castron approach to climate-smart agriculture
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich. Reihe Energie & Umwelt / Energy & Environment 573, XVIII, 127 S. (2022)2022 = Universität Bonn, Diss., 2021
Lack of basic sanitation and appropriate waste management, limited access to mineral and organic fertilizers, and land degradation are major public health and food security challenges, particularly in developing regions with financial and infrastructural limitations such as in Sub-Saharan Africa. Developing integrated interventions that address these challenges is of great relevance and is becoming more urgent as the effects of climate change increase and as the global population continuously rises.

Sequential and coupled inversion of time-lapse borehole GPR measurements for vadose zone model parameterization
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 565, XX, 121 (2022)2022 = Dissertation, Univ. Bonn, 2021
A profound understanding of the infiltration dynamics into the vadose zone is crucial to ourcapacity to link surface and subsurface processes for the description of the hydrologic cycle. Akey to establish reliable models describing the infiltration process is the knowledge of the soilhydraulic parameters. [...]

Topological magnonic properties of two-dimensional magnetic materials
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Schlüsseltechnologien / Key Technologies 253, 154 p. (2022)2022 = Dissertation, RWTH Aachen University, 2022
Spintronics is based on the transport of information by the spin of electronsrather than charge current so as to avoid the Joule heat. Among it,magnons, as the most elementary excitations in magnetic materials, haveemerged as a prominent tool in electrical and thermal manipulation andtransport of spin. [...]
