HPLC-IMER as a Fast and Sensitive Method for the Determination of Sulfur Dioxide in Foodstuffs
(2009-10-19)
HPLC-IMER (HPLC with an immobilized enzyme reactor) is a combination of an isocratic HPLC system with an integrated immobilized enzyme reactor and electrochemical detection for the analysis of sulfites. The aim of this ...
Cavitands, Helicates and Macrocycles: Unleashing the Power of Weak Non-Covalent Interactions
(2009-11-12)
In the course of the development of supramolecular chemistry, weak non-covalent interactions have gained tremendous importance. In this work, comprehensive massspectrometric investigations combined with theoretical ...
Development and Application of London Dispersion Corrections for Electronic Structure Methods
(2020-05-19)
Mean-field electronic structure methods like Hartree–Fock ( HF ) or Kohn–Sham ( KS ) Density Functional Theory ( DFT ) do not account for long-range correlation effects and consequently not for London Dispersion ......
Computation of Electronic Excitation Spectra of Large Biomolecular Systems
(2020-11-30)
This thesis presents the theoretical investigation of electronic excitation spectra and nonlinear responses of large biomolecular systems (e.g., proteins or deoxyribonucleic acid fragments), with a particular focus on the ...
The Carbon Sulfide Anions (C4S4)2− and β-(C3S5)2−: A Crystallographic Study on the Metal Salts and the Hydrolysis and Oxidation Properties
(2009-02-20)
Tetrathiosquarate (C4S4)2− forms water soluble compounds of salt like character with the earth alkaline ions from Mg2+ to Ba2+. While Ca2+ and Sr2+ ...
Enzymkatalysierte C-C Knüpfung: Reaktionstechnische Untersuchungen zur Synthese pharmazeutischer Intermediate
(2009-03-10)
In dieser Arbeit werden Möglichkeiten untersucht, durch enzymkatalysierte asymmetrische C C-Knüpfung, relevante pharmazeutische Intermediate zu synthetisieren. Das Ziel ist es die Synthese unterschiedlicher Produkte durch ...
Emerging Chemical Patterns for Virtual Screening and Knowledge Discovery
(2009-02-03)
The adaptation and evaluation of contemporary data mining methods to chemical and biological problems is one of major areas of research in chemoinformatics. Currently, large databases containing millions of small organic ...
Aktivierung von Phosphanen durch Donor / Akzeptor Wechselwirkungen: Untersuchungen zur Synthese und Struktur
(2009-01-29)
Ein zentrales Ziel dieser Arbeit war es, Wege aufzuzeigen, die den Zugang zu hochreaktiven niedervalenten Phosphorverbindungen unter kinetisch kontrollierten Bedingungen in Lösung ermöglichen sollten. Dieses Ziel sollte ...
Anwendungen der HPLC-Triple Quadrupol Massenspektrometrie in der forensischen und klinischen Toxikologie bei der Analytik von Opioiden
(2009-02-03)
In der modernen toxikologischen Analytik sind chromatographische Verfahren nicht mehr wegzudenken. Bereits seit über zwei Jahrzehnten spielen dabei die Hochleistungsflüssigchromatographie (HPLC) und die Gaschromatographie ...
Carbon Nanotube Substrates for Tissue Engineering Applications: Analysis of surface nanotopography, cellular adhesion, and elasticity
(2009-01-16)
The present study investigates the applicability of multiwalled carbon nanotubes in creating novel nanostructured matrices exhibiting biomimetic designed features. The thus produced CNT-based constructs were employed to ...
