Single Chip Dynamic Nuclear Polarization Microsystems

Nergiz Sahin Solmaz

Nuclear magnetic resonance (NMR) methods are powerful tools employed in many fields, including physics, chemistry, material science, biology, and medicine. The use of NMR methodologies in an even wider range of applications is often hindered by the relativ ...

Solid-state NMR spectroscopy

David Lyndon Emsley

Solid-state nuclear magnetic resonance (NMR) spectroscopy is an atomic-level method to determine the chemical structure, 3D structure and dynamics of solids and semi-solids. This Primer summarizes the basic principles of NMR spectroscopy as applied to the ...

SPRINGERNATURE2021

Solid-state NMR can provide information about the atomic level structure and dynamics of materials. It directly probes symmetry and structure at nuclear sites, and is especially useful for investigation of disordered or amorphous solids that lack long rang ...

Long-lived nuclear spin states of magnetically equivalent protons by means of dissolution dynamic nuclear polarization

Daniele Mammoli

Nuclear Magnetic Resonance (NMR) is one of the most versatile techniques since it enables the characterization of solid, liquid and gaseous systems in a plethora of in-vitro and in-vivo experiments. Despite its multidisciplinary scope, it still suffers fro ...
