Die vorliegende Arbeit fokussiert sich auf die Aktivierung von Interelementbindungen der Elemente Bor, Silicium und Zinn. Der erste Teil dieser Arbeit beschreibt die Aktivierung von Diborbindungen ...

Theoretische Untersuchung der spektroskopischen Eigenschaften biologischer und synthetischer molekularer Spincluster

Ghassemi Tabrizi, Shadan (2017)

Molekulare Spincluster aus zwei bis acht austauschgekoppelten Übergangsmetallzentren erfüllen in Metalloproteinen vielfältige Funktionen, vor allem beim Elektronentransfer und in der biochemischen ...

Bacillus subtilis as heterologous host for the secretory production of the non-ribosomal cyclodepsipeptide enniatin

Zobel, Sophia; Kumpfmüller, Jana; Süssmuth Roderich D.; Schweder, Thomas (2014)

The heterologous expression of genes or gene clusters in microbial hosts, followed by metabolic engineering of biosynthetic pathways, is key to access industrially and pharmaceutically relevant com...

Redox processes of heme proteins and metalloporphyrins studied by vibrational spectroelectrochemistry

Kielb, Patrycja (2017)

Heme proteins belong to the most abundant and widely used metallo-proteins throughout the biosphere. Their biocatalytic, electron transporting and oxygen-binding functions are ubiquitous in many li...

Layered and composite biopolymers: mechanical, physical and antimicrobial properties

Kaygusuz, Hakan (2017)

In this thesis, two oppositely charged biopolyelectrolytes –alginate and chitosan- were focused on. The interactions between these biopolymers and the effect of surfactants on these biopolymers wer...

The impact of substrate curvature on the self-assembly of liquid crystals

Püschel-Schlotthauer, Sergej (2017)

The interplay of anisotropic molecular interactions, nonlinearities of the orientational field, and long-range orientational correlations make the physics of liquid crystals both challenging and fa...

Ein unerwarteter Effekt der Reaktivitätssteigerung bei Catechol-Oxidase-Modellen

Gülzow, Jana (2017)

This dissertation presents the synthesis and characterisation of two new tetradentate ligands, 2-(6-(1,1-di(pyridine-2-yl)ethyl)pyridine-2-yl)-2-methylpropane-1,3-diol (Py3OH, L1) and 2-(6-(1,1-di(...

Metastable transition metal oxides, oxide nitrides, and nitrides

Lüdtke, Tobias Clemens (2017)

In the present cumulative work the successful synthesis of new compounds of transition metals, with focus on metastable oxides and oxide nitrides of the vanadium and chromium group, is reported. δ...

Diffusion pathways and activation energies in crystalline lithium-ion conductors

Wiedemann, Dennis; Islam, Mazharul M.; Bredow, Thomas; Lerch, Martin (2017)

Geometric information about ion migration (diffusion pathways) and knowledge about the associated energy landscape (migration activation barriers) are essential cornerstones for a comprehensive und...

Synthese photochromer Aminosäuren und deren Einbau in Peptidstrukturen

Kitzig, Sebastian (2017)

Die gesteuerte Untersuchung biochemischer Vorgänge und Zusammenhänge zur Behandlung von diversen Krankheitsbildern ist eines der Ziele der modernen Forschung. Dabei erlaubt die Verwendung von photo...

Transferhydrosilylierung

Oestreich, Martin (2016)

Es steht außer Frage, dass Transferhydrierung ein gängiges Verfahren in der Industrie und der akademischen Welt ist. Trotz ihrer Vielfältigkeit war die konzeptionell verwandte Transferhydrosilylier...

Transfer hydrosilylation

Oestreich, Martin (2016)

Transfer hydrogenation is without question a common technology in industry and academia. Unlike its countless varieties, conceptually related transfer hydrosilylations had essentially been unreport...

NAD(H)-coupled hydrogen cycling - structure-function relationships of bidirectional [NiFe] hydrogenases

Horch, Marius; Lauterbach, Lars; Lenz, Oliver; Hildebrandt, Peter; Zebger, Ingo (2012)

Hydrogenases catalyze the activation or production of molecular hydrogen. Due to their potential importance for future biotechnological applications, these enzymes have been in the focus of intense...

Biological effects of paenilamicin, a secondary metabolite antibiotic produced by the honey bee pathogenic bacterium Paenibacillus larvae

Garcia-Gonzalez, Eva; Müller, Sebastian; Hertlein, Gillian; Heid, Nina; Süssmuth, Roderich D.; Genersch, Elke (2014)

Paenibacillus larvae is the etiological agent of American Foulbrood (AFB) a world-wide distributed devastating disease of the honey bee brood. Previous comparative genome analysis and more recently...

Evolution of fluorinated enzymes: an emerging trend for biocatalyst stabilization

Biava, Hernan; Budisa, Nediljko (2014)

Nature uses remarkably limited sets of chemistries in its repertoire, especially when compared to synthetic organic chemistry. This limits both the chemical and structural diversity that can ultima...

Enzyme-modified particles for selective biocatalytic hydrogenation by hydrogen-driven NADH recycling

Reeve, Holly A.; Lauterbach, Lars; Lenz, Oliver; Vincent, Kylie A. (2015)

We describe a new approach to selective H-2-driven hydrogenation that exploits a sequence of enzymes immobilised on carbon particles. We used a catalyst system that comprised alcohol dehydrogenase,...
