Local environments and lithium ion dynamics in the binary lithium silicides Li15Si4, Li13Si4, and Li7Si3 have been characterized by detailed variable temperature static and magic-angle spinning (MAS) NMR spectroscopic ...

Quantification of the crystalline versus amorphous fraction is an important objective for the structural characterization of glass-ceramics. Owing to its well-documented ability of differentiating between crystalline and ...

The ternary silicide 'LA IND.2''LI IND.2''SI IND.3' was synthesized from the elements in a sealed niobium tube. 'LA IND.2''LI IND.2''SI IND.3' was characterized by powder and single crystal X-ray diffraction: 'CE IND.2''LI ...

Systematic vanadosilicate syntheses were performed using derivatives of 2,6-dimethylpiperidine as organic structure-directing agents (SDAs). Physicochemical analyses of the vanadosilicate materials obtained were carried ...

Local environments and lithium ion dynamics in the binary lithium silicide Li12Si7, and the analogous germanium compound have been characterized by detailed 6Li, 7Li, and 29Si variable temperature static and magic-angle ...

Glasses along the composition line 0.5Al2O3–xSiO2 (1 ≤ x ≤ 6) were prepared via a novel sol-gel route using tetraethylorthosilicate and aluminum lactate as precursors. The structural evolution from solution to gel to glass ...

Foram sintetizados neste trabalho novos vanadosilicatos, para suas sínteses foram utilizadas moléculas orgânicas derivadas de 3,5-dimetilpiperidina (SDAs 1 – 4) e 2,6-dimetilpiperidina (SDAs 5 – 8) em sua mistura reacional. ...

A new metallosilicate based on yttrium was synthesized and characterized by XRD, FT-IR, 29Si MAS-NMR, and 89Y MAS-NMR. The mixed framework of the material was confirmed by the detection of distinct chemical shift groups ...
