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,...

Xenomicrobiology: a roadmap for genetic code engineering

Acevedo-Rocha, Carlos G.; Budisa, Nediljko (2016)

Biology is an analytical and informational science that is becoming increasingly dependent on chemical synthesis. One example is the high-throughput and low-cost synthesis of DNA, which is a founda...

Multilayered lipid membrane stacks for biocatalysis using membrane enzymes

Heath, George R.; Li, Mengqiu; Rong, Honling; Radu, Valentin; Frielingsdorf, Stefan; Lenz, Oliver; Butt, Julea N.; Jeuken, Lars J. C. (2017)

Multilayered or stacked lipid membranes are a common principle in biology and have various functional advantages compared to single-lipid membranes, such as their ability to spatially organize proc...

Introduction to the special issue on small-angle scattering

Gradzielski, Michael; Allen, Andrew J. (2016)

Future challenges in heterogeneous catalysis: understanding catalysts under dynamic reaction conditions

Kalz, Kai F.; Krähnert, Ralph; Dvoyashkin, Muslim; Dittmeyer, Roland; Gläser, Roger; Krewer, Ulrike; Reuter, Karsten; Grunwaldt, Jan-Dierk (2017)

In the future, (electro-) chemical catalysts will have to be more tolerant towards a varying supply of energy and raw materials. This is mainly due to the fluctuating nature of renewable ener-gies....

Sense codon emancipation for proteome-wide incorporation of noncanonical amino acids

Bohlke, Nina; Budisa, Nediljko (2014)

One of the major challenges in contemporary synthetic biology is to find a route to engineer synthetic organisms with altered chemical constitution. In terms of core reaction types, nature uses an ...

Structure-activity investigations of mixed Ni-Fe oxides as catalysts for electrochemical water splitting

Görlin, Eva Mikaela Charlotte (2017)

A balanced utilization of energy requires new approaches in catalysis, to reach sufficient levels of production of renewable energy. Specifically, there is a need of efficient catalysts for energy ...

Amphiphile Polymere als Solubilisatoren für schwer wasserlösliche Wirkstoffe

Nguyen-Kim, Viet (2017)

Pluronics sind amphiphile Blockcopolymere, die schwer lösliche organische Wirkstoffe in Wasser mizellar solubilisieren. Obwohl Pluronics breit eingesetzt werden, waren detaillierte Solubilisierungs...

Nano-contact transfer with gold nanoparticles on PEG hydrogels and using wrinkled PDMS-stamps

Yesildag, Cigdem; Tyushina, Arina; Lensen, Marga C. (2017)

In the present work, a soft lithographic process is used to create nanometer-sized line patterns of gold nanoparticles (Au NPs) on PEG-based hydrogels. Hereby nanometer-sized wrinkles on polydimeth...
