Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
Nuclear magnetic resonance (NMR) is used for a large array of applications, ranging from chemical characterization to oil drilling to medical imaging. In these fields NMR is used as an investigational tool, but new techniques and applications are continuou ...
The phenomenon of magnetism is one of the key components of today's technological progress. Magnetic interactions and magnetic materials are essential for the scientific disciplines of physics, chemistry and biology, making this subject truly multidiscipli ...
The molecular dynamics of a series of organometallic complexes covalently bound to amorphous silica surfaces is determined experimentally using solid-state nuclear magnetic resonance (NMR) spectroscopy and density functional theory calculations (DFT). The ...
Nuclear magnetic resonance (NMR) spectroscopy can be applied in vivo to measure static or dynamic biochemical information, e.g., concentrations of metabolites and metabolic fluxes, using various nuclei such as 1H, 13C, 31P and 15N. The work of this thesis ...
The invention relates to new proteins called alkylcytosine transferases (ACTs) derived from O-alkylguanine-DNA alkyltransferase, and to substrates for ACTs specifically transferring a label to these ACTs and to fusion proteins comprising these. The subs ...
The MCM-41 supported hydrides [( SiO)(2)TaH], 1a, and [( SiO)(2)TaH3], 1b, cleave N-H bonds of ammonia at room temperature to yield the well-defined imido amido surface complexes [( SiO)(2)Ta-(NH)(NH2)], 2, and 2 center dot NH3. Additionally, the surface s ...
We show that double-resonance spectra recorded during the simultaneous absorption of x-ray and microwave (MW) photons are a fingerprint of the perturbed electronic configuration of atomic species driven to ferromagnetic resonance. X-ray absorption measurem ...
Recent advances in solid state NMR spectroscopy have made possible the understanding of surface species and active sites of heterogeneous catalysts at a molecular level. This tutorial review describes solid state NMR spectroscopy, what are the possible tec ...
We demonstrate that it is possible to record site-specific spin-lattice relaxation rates for the majority of C-13 sites in uniformly C-13 and N-15 labeled solid proteins as a result of the slowing down of proton-driven spin diffusion at sample spinning fre ...
