The Mononuclear Metal-Binding Site of Mo-Nitrogenase Is Not Required for Activity

The biological N-2-fixation process is catalyzed exclusively by metallocofactor-containing nitrogenases. Structural and spectroscopic studies highlighted the presence of an additional mononuclear metal-binding (MMB) site, which can coordinate Fe in additio ...

Complexation Strategies towards Challenging Group 9 Metal Cyclopentadienyl Scaffolds

Aragorn Nathan Laverny

Cyclopentadienyl (Cp) metal complexes and their chiral counterparts (CpX) have enabled the development of challenging C-H activation transformations. While major progresses were made in developing new chiral CpX complexes and exploring their reactivity, th ...

Improving time-resolution and sensitivity of in situ X-ray photoelectron spectroscopy of a powder catalyst by modulated excitation

Davide Ferri, Oliver Kröcher, Filippo Buttignol

Ambient pressure X-ray photoelectron spectroscopy (APXPS) is a powerful tool to characterize the surface structure of heterogeneous catalysts in situ. In order to improve the time resolution and the signal-to-noise (S/N) ratio of photoemission spectra, we ...

Computational characterisation of the selectivity and binding mode of mono- and binuclear transition metal based anticancer compounds

Thibaud Edouard Alistair von Erlach

The rising resistance and the severe side effects associated with classical anticancer drugs such as cisplatin or mercaptopurines has triggered the development of novel antitumourous agents based on transition metal (e.g. ruthenium, osmium, and gold) organ ...

Carbon dioxide reduction by dinuclear Yb(ii) and Sm(ii) complexes supported by siloxide ligands

Marinella Mazzanti, Farzaneh Fadaei Tirani, Davide Toniolo

Two dinuclear homoleptic complexes of lanthanides(II) supported by the polydentate tris(tertbutoxy) siloxide ligand ([Yb2L4], 1-Yb and [Sm2L4], 1-Sm, (L = (OtBu)3SiO−)) were synthesized in 70–80% yield and 1-Sm was crystallographically characterized. 1-Yb ...

Catalyst design for the transformation of CO2 into value-added products.

Felix Daniel Bobbink

The mass-utilization of fossil resources has led to a dramatic increase in carbon dioxide (CO2) production, most of which is released directly into the Earth's atmosphere, resulting in global warming. Efforts to contain CO2 emissions and to capture, store ...

Water Exchange on [Ln(DO3A)(H2O)2] and [Ln(DTTA–Me)(H2O)2]− Studied by Variable Temperature, Pressure, and Magnetic Field NMR

Lothar Helm, Shima Karimi

Water exchange kinetics of [Ln(L)(H2O)2]x complexes (Ln = Pr, Nd, Dy, Tm, and Yb; L = DO3A and DTTA–Me) were studied by 17O NMR spectroscopy as a function of temperature, pressure, and frequency and by 1H nuclear magnetic relaxation dispersion. Water excha ...

On-Surface Assembly and Reactions of Organic Molecules in Ultra-High Vacuum

Claudius Morchutt

This thesis comprises the study of two types of 2D materials, those stabilized by non-covalent and those by covalent interactions. They are synthesized and studied on well-defined metallic surfaces in ultra-high vacuum (UHV). The self-assembly of terephtha ...

Molecular Hydrogen Messengers Can Lead to Structural Infidelity: A Cautionary Tale of Protonated Glycine

Thomas Rizzo, Antoine Louis Claude Masson, Evan Rowland Williams

The effects of tagging protonated glycine with either He or with between 1 and 14 H2 molecules on the infrared photodissociation (IRPD) spectra and the ion structure was investigated. Differences in the IR spectra with either a single He atom or H2 molecul ...

Heterometallic Fe-2(II)-U-V and Ni-2(II)-U-V Exchange-Coupled Single-Molecule Magnets: Effect of the 3d Ion on the Magnetic Properties

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Uranium-based compounds have been put forward as ideal candidates for the design of single-molecule magnets (SMMs) with improved properties, but to date, only two examples of exchange-coupled 3d-5f SMM containing uranium have been reported and both are bas ...
