23 Na NMR microimaging is described to map, for the first time, the sodium distribution in living plants. As an example, the response of 6-day-old seedlings of Ricinus communis to exposure to sodium chloride concentrations from 5 to 300 mM was observed in vivo using 23 Na as well as 1 H NMR microima
The modification of surface hydroxyl groups with sodium in a series of Na,CO,-y-Al,O, catalysts was investigated as a function of both the Na,CO, loading and the calcination temperature by means of 'H magic angle spinning (MAS) and 'H("Na} spin-echo double resonance NMR techniques. The 'H NMR experi
