Ultra Low Temperature Microturbine for Magic Angle Spinning System.

Nuclear magnetic resonance (NMR) is a nondestructive technique used to characterize molecular structure and dynamics with atomic resolution. In solid-state NMR, magic angle spinning (MAS) is commonly implemented to improve spectral resolution by partially averaging anisotropic interactions. To further improve NMR sensitivity, dynamic nuclear polarization (DNP) is utilized to transfer the. Introduction Since their invention in 2007, 1 magic angle coil spinning (MACS) micro-resonators have earned a special place among available NMR detectors for mass- and volume-limited samples. This is due to several advantages that are intrinsic to the very nature of these devices, which brought significant improvements in the way magic angle spinning (MAS) NMR measurements are being performed. 1. Introduction. In the past decade, the field of magic-angle spinning (MAS) nuclear magnetic resonance (NMR) has made significant strides. This technique has advanced to the level where we can now determine structures and characterize dynamics of complex systems, including large protein assemblies, at atomic resolution.

Tensors and NMR with Magic Angle Spinning Fundamentals of.

Magic Angle Spinning (MAS) is one of the most powerful methods used in nuclear magnetic resonance (NMR) and is the only technique that allows a high-resolution NMR spectrum to be acquired on solids, semi-solids, or a mixture thereof. There are a number of types of studies using NMR that ideally should be done at elevated pressure.

Made available by U.S. Department of Energy Office of Scientific and Technical Information. High-resolution magic angle spinning MRS of breast cancer tissue Abstract High-resolution magic angle spinning (HR MAS) may develop into a new diagnostic tool for studying intact tissue samples, and several types of cancer have been investigated with promising results. Magic-angle spinning is routinely used to average anisotropic interactions in solid-state nuclear magnetic resonance (NMR). Due to the fact that the homonuclear dipolar Hamiltonian of a strongly coupled spin system does not commute with itself at different time points during the rotation, second-order and higher-order terms lead to a residual dipolar line broadening in the observed resonances.

Magic-angle-spinning NMR used to probe protein/microtubule assembly at.

Magic angle spinning: An MRI technique in which rigid systems averaging of chemical shift anisotropy (a line) or “resolution” method is accomplished mechanically. MAS can, in principle and occasionally in practice, be used to eliminate another important line-broadening interaction, that of the magnetic dipole–dipole interaction between pairs. Magic-angle-spinning NMR is a very powerful technique which allows high-resolution spectra to be obtained from solids, even when the sample is microcrystalline or amorphous. The principles of the technique are described and examples given of its usefulness in many areas of chemistry with special stress being laid on aluminosilicate catalysts. Solid-state cross-polarization, magic-angle sample spinning carbon-13 nuclear magnetic resonance spectra have been recorded on chlorophyll a- water aggregates, methyl pyrochlorophyllide a and methyl pyropheophorbide a (derivatives that lack a phytyl chain). Spectra have also been collected under a decoupling regime in which resonances of.

Magic Angle Spinning in Solid State n.m.r. Spectroscopy.

. Rapid specimen rotation about an axis inclined at the 'magic angle' of 540 44' to the Zeeman field direction can remove many sources of broadening from the n.m.r. spectrum of a solid and enable finer features to be revealed. In this paper the basic principles of magic angle spinning are given and the effects on the chemical shift. Magic-Angle-Spinning (MAS) ( engl. für Drehung/Rotation im magischen Winkel) ist eine Technik zur Verbesserung der Signalqualität in der Festkörper - Kernspinresonanzspektroskopie (NMR-Spektroskopie), die auf der sehr schnellen Rotation der Probe während der Messung beruht.
