Fixed drug eruption (FDE) is a distinctive pattern of cutaneous adverse drug reaction. Characteristically the eruption recurs at the same site on re exposure to the offending agent. Aim of this study was to evaluate and identification of the various

The effect of addition of small amounts of P2O5 in the lithium disilicate glasses results in the scavenging of lithium metal ions by a phosphate group, Li3PO4. As a consequence of the scavenging, the silicate network partially repolymerises. The phos

High resolution nuclear magnetic resonance (NMR) has been used to measure relaxation times, T 1 , in alkali silicate glasses. Two-component relaxation was observed in lithium silicate glasses. In glasses close to the sodium disilicate composition, th

Magic angle spinning nuclear magnetic resonance (MAS NMR) is used to measure the 29Si chemical shift and full width at half maximum in Na2O·2SiO2·xMnO for 0.0≤x≤0.8 glasses. The large space varying magnetic field of the paramagnetic centers inc

Several crystallographically non-equivalent structures of sodium disilicate are known to exist. Successive heat treatments of the sodium disilicate glasses show α-, β-, γ- and δ-Na2Si2O5 as the devitrification products, depending upon the nature

MAS-NMR of binary lithia-silica glasses, containing 25–39 mol% Li2O, shows that the Qn distribution largely follows that predicted by the binary (constrained) model but with some deviation when the lithia content exceeds 29 mol%. The deviation cons

MAS-NMR has been used to explore the structure of sodium phospho-alumino-silicate glasses. Adding P 2 O 5 to sodium silicates causes repolymerisation of the silicate network and formation of sodium ortho-, pyro- and eventually metaphosphate units. At

When P2O5 is added to alkali disilicates initially the phosphorus scavenges the alkali and polymerises the network. For larger concentrations of P2O5 the network changes radically from the conventional silicate glass where silicon is four coordinated
