Solid state Si-29 and P-31 MAS NMR have been used to investigate the microstructural changes occurring in phosphosilicate gels during their conversion from a gel to the corresponding gel-derived glasses by heating. The studied gels have the molar com

The application of NMR methods to the non-destructive testing of thermoplastic composites is discussed. NMR imaging of the polymer matrix is restricted to the detection of defects in excess of 5 mm using standard instrumentation. Higher resolution ca

13C CP MAS NMR spectroscopy was used to characterize α-C:H materials generated from methane and hydrogen mixtures using a microwave plasma. Dipolar dephasing experiments indicate a range of Tdd making quantification of quaternary “diamond”-like

Publisher Summary This chapter focuses on the developments in the techniques of solid state nuclear magnetic resonance (NMR). The most important obstacle to the wider application of solid state NMR is the low sensitivity of the technique. This arises

Nuclear magnetic resonance imaging has been used as a method of void detection in carbonfibre reinforced polymer composites. This is accomplished by observation of signal from water molecules which have ingressed into surface-connected defect regions

Pade–Laplace analysis has been proposed as a method for identifying the number of exponential components in a multi-exponential decay. The usefulness of this method has been examined by computer simulations, for data sets typical of T1ρ measuremen
