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 ...
Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...
The quantum antiferromagnet Cu2Te2O5Br2 was investigated by NMR and nuclear quadrupole resonance (NQR). The Te-125 NMR investigation showed that there is a magnetic transition around 10.5 K at 9 T, in agreement with previous studies. From the divergence of ...
The modulation of spin echoes by homonuclear scalar couplings render the determination of transverse relaxation rates of individual spins difficult, in particular for molecules that are isotopically enriched in 13C or 15N, and for all molecules with scalar ...
A general approach for structural interpretation of local disorder in partially ordered solids is proposed, combining high-resolution two-dimensional (2D) nuclear magnetic resonance (NMR) and first principles calculations. We show that small chemical shift ...
A widely-tunable single-mode 1.3 mu m vertical-cavity surface-emitting laser structure incorporating a microelectromechanical system-tunable high-index-contrast subwavelength grating (HCG) mirror is suggested and numerically investigated. A linear tuning r ...

A series of salts composed of the coordinatively unsatd. areneruthenium β-diketiminato cation and different anions, [(η6-C6H6)Ru(ArN:CMeCHCMe:NAr)][X] (1-4; Ar = 2,6-dimethylphenyl; X = OTf-, BF4-, PF6-, BPh4-) and [(η6-C6H6)Ru(ArN:CMeCHCMe:NAr)][BArF4] [5 ...
We demonstrate that heteronuclear decoupling using a Phase-Inverted Supercycled Sequence for Attenuation of Rotary Resonance (PISSARRO) is very efficient at high spinning frequencies (v(rot) = 60 kHz) and high magnetic fields (900 MHz for protons at 21 T) ...
This thesis describes new methods for the detection of 14N nuclei by solid-state nuclear magnetic resonance. So far, the low natural abundance (0.4 %) 15N isotope has been widely used to study nitrogen-containing samples because of its spin-1/2 nature. The ...
The applicability, reliability, and repeatability of Si-29 MAS NMR for determination of the quantities of alite (Ca3SiO5) and belite (Ca2SiO4) in anhydrous Portland cement was investigated in detail for 11 commercial Portland cements and the results compar ...
