Recently, it was found by the authors of this study that glasses of a special composition have an ability to remove some hazardous ions from waste solutions. In the present study, a SiO(2)-B(2)O(3)-CaO-Na(2)O glass system has been chosen to remove

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

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

New nano hybrid material (ZrO(2)/B(2)O(3)) was synthesized and applied as a sorbent for the separation and/or preconcentration of Co(II), Cu(II) and Cd(II) in water and tea leaves prior to their determination by flame atomic absorption spectrometry. Synthesized nano material was

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.
