Divalent Mn2+ ions containing 20ZnO+xLi2O+(30-x)K2O+50B2O3(5≤x≤25) mol% glasses are prepared by using melt quench technique and are characterized by several spectroscopic techniques. Various physical parameters are evaluated from the measured values of density and refractive index for the observation of mixed

Al-rich single-crystal mullite [Al(2)(Al(2.8)Si(1.2))O(9.6)] nanowires were prepared by B(2)O(3)-doped molten salts synthesis. The nanowires have diameters in the range 30-50 nm and typical lengths of 1 microm. The mullite nanowires were well dispersed and facile to obtain.

Using a two-dimensional multiple-quantum (MQ) double rotation (DOR) experiment the contributions of the chemical shift and quadrupolar interaction to isotropic resonance shifts can be completely separated. Spectra were acquired using a three-pulse triple-quantum z-filtered pulse sequence and subsequently sheared along
