87Sr solid-state NMR as a structurally sensitive tool for the investigation of materials : antiosteoporotic pharmaceuticals and bioactive glasses

This pioneering work on 87Sr NMR spectroscopy was made possible by the high magnetic fields available within the UK 850 MHz Solid-state NMR facility. Iuga is manager of this facility and engaged with the work on a scientific and technical level by implementing and optimising several signal enhancement methods such as DFS (double frequency sweep), QCPMG (quadrupolar Carr-Purcell-Meiboom-Gill), and WURST (wideband, uniform rate, and smooth truncation). This increased the sensitivity to a level such that it was possible to demonstrate 87Sr NMR as a valuable tool for investigating strontium environments in disordered phases, such as bioactive glasses.
