A major challenge in cancer biology is to monitor and understand cancer metabolism in vivo with the goal of improved diagnosis and perhaps therapy. Because of the complexity of biochemical pathways, tracer methods are required for detecting specific enzyme ...
By shining millimeter waves upon a sample, Dynamic Nuclear Polarization (DNP) provides a way to enhance Nuclear Magnetic Resonance (NMR) signals. Here we report on our efforts to realize a tunable gyrotron at 263.5 GHz and design consideration for coupling ...

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 ...
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 ...
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 ...
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 ...
Solution-state nuclear magnetic resonance method for singlet-state nuclear magnetic resonance-spectroscopy, involves performing transformation of zero-quantum coherences into singlet-state populations by radio frequency irradiation ...
