Sterically confined second-sphere receptor chromophores for optical molecular recognition and photocatalysis
(Universität Ulm, 2016-08-30)
The investigation of molecular processes and interactions through visible light is of fundamental importance for a wide range of technological and biological applications. The chromophores developed in this work have ...
Adsorption behavior and structure formation of ionic liquids on single crystalline surfaces
(Universität Ulm, 2017-02-10)
In the present thesis the interaction of the ionic liquids [BMP][TFSA], [OMIM][TFSA] and [EMIM][TFSA] on the single crystalline surfaces Au(111), Ag(111), Cu(111) and TiO2(110) was investigated with STM and XPS under UHV ...
"Development and optimization of bibenzimidazole transition metal chromophores for luminescent ion sensing and photocatalysis"
(Universität Ulm, 2016-10-19)
The recognition and fixation of highly reactive systems by binding within defined spatial geometries is a fundamental principle of the enlivened nature. In the last four decades this biologically tenet was transferred to ...
Measurement of reduced dipole matrix elements in 40Ca+ and construction of a scalable light-ion interface
(Universität Ulm, 2017-01-10)
In the first part of this thesis, a method for determining transition dipole matrix elements is introduced. It combines measuring absorptive and dispersive atom-light interactions off-resonant to the transition in question ...
Phase retrieval methods in inline-holography
(Universität Ulm, 2016-08-02)
Quantitative phase imaging, i.e. the detection of the phase delay imposed by a biological cell or thin transparent sample on the incoming electromagnetic wave, allows not only to visualize the otherwise hidden structure ...
Mäuse sprechen nicht - werden ihre angeborenen, emotionalen Lauterzeugungen durch Foxp2-Mutationen beeinflusst?
(Universität Ulm, 2016-07-08)
Heterozygote Mutationen im FOXP2 Gen verursachen beim Menschen erhebliche Defizite im sprachlichen Ausdruck (Lai et al., 2001; MacDermot et al., 2005). Mäuse lernen ihre Vokalisationen nicht. Sie geben Laute instinktiv in ...
Predicting angiosperm tree mortality based on embolism resistance, cambium vitality and intervessel pit membrane thickness
(Universität Ulm, 2017-02-28)
Drought is one of the most challenging environmental factors inducing world-wide forest die-back and tree mortality. In this thesis, xylem embolism resistance (P50, i.e., the xylem water potential at 50% loss of hydraulic ...
Development of all solid state fluoride ion batteries based on thin film electrolytes
(Universität Ulm, 2017-03-14)
For current solid state fluoride ion battery, a critical problem is that the practical capacity is considerably below that of the theoretical value and fades rapidly during the further cycles. One reason for this problem ...
Mimicking the active centers of iron sulfur proteins via reactions of iron sulfur cations in a linear octopole ion trap
(Universität Ulm, 2017-06-13)
Metalloproteins are ’macromolecular machines’ and cover a vast amount of important functions which are essential for all living organisms. Proteins are able to transduce signals, replicate DNA, or catalyze chemical reactions. ...
Corrosion resistant cathode catalyst support materials for polymer electrolyte membrane fuel cell
(Universität Ulm, 2017-08-08)
Polymer Electrolyte Membrane Fuel Cells (PEMFC) having high power density and low degradation are considered a viable option for future emission free mobility. In order to minimize the noble metal demand, platinum ...
