A unique self-organization of optically active nanoparticles of CdS on a silicon surface forming nanoring structures (see Figure and inside cover) is presented. Tunneling luminescence mapping on these structures show that there is direct corresponden

29Si and 23 Na magic angle spinning (MAS) NMR has been used as an atomic probe for structural characterisation of soda-lime-silicate glasses. The glasses studied are based on the composition (CaO) x (Na 2 Si 3 O 7 ), where x is varied from x = 0 to x

Alkali X-ray absorption fine structure (XAFS) spectra from K x Cs (1− x ) Si 2 O 5 glasses measured at room temperature reveal changes in the Debye–Waller factors of nearest neighbour oxygen shells as the mixed alkali composition is altered. The

EXAFS data analysis using a multiple-scattering method for metal-ion substituted microporous solids are presented. It is shown that such an approach yields the best description of local structure for the first and the second shell neighbours around t
