Nuclear magnetic resonance (NMR) spectroscopy enables determination of membrane protein structures in lipid environments, such as micelles and bilayers. This chapter outlines the steps for membrane-protein structure determination using solution NMR with micelle samples, and solid-state NMR with oriented lipid-bilayer by: 1. Introduction. Alkali borate glasses have been extensively studied due to their potential importance as fast ion conductors,,, and alkali borosilicates as model systems for highly durable nuclear wasteforms,.One of the most valuable techniques for probing short-range structure in glasses is NMR spectroscopy,,,.Boron NMR has been used for decades to quantify the types of borate Cited by:
The structure of quenched aluminosilicate glasses with Na2O/Al2O3 > 1 has been studied by high-resolution nuclear magnetic resonance spectroscopy. The aluminum in the structure of the glasses is shown to be in fourfold coordination. Increasing the sodium oxide content of the glasses reduces the degree of polymerization in their structure and leads to a nonuniform nonbridging Cited by: 1.

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with . - Double channel Bruker Avance III spectrometer with multinuclear capability (1H/15NP) - Variable temperature to 80C. High-resolution MAS NMR (gel NMR) - a MHz triple resonance HR/MAS probe (1HPC, optimised for 13C); - an MHz double resonance HR/MAS probe (1HC, optimised for 13C).

Structure and dynamics of Oxyde Melts and Glasses: a view from multinuclear and high temperature NMR Article in Journal of Non-Crystalline Solids () January with 69 Reads. Techniques of solid state nuclear magnetic resonance (NMR) spectroscopy are constantly being extended to a more diverse range of materials, pressing into service an ever-expanding range of nuclides including some previously considered too intractable to provide usable results.
At the same time, new developments in both hardware and software are being introduced and refined.5/5(1). High resolution multinuclear nuclear magnetic resonance studies of oxide glasses.

In a pioneering high temperature NMR study, Stebbins et al. 59 reported 27 Al chemical shifts for four compositions of the NaF–AlF 3 –Al 2 O 3 system. They noticed that these chemical shifts were systematically much higher in the liquid than in the related solid phases.
