New layered double hydroxides intercalated with substituted pyrroles. 1. In situ polymerization of 4-(1H-pyrrol-1-yl)benzoate
(Elsevier B.V., 2006-05-01)
The two-dimensional hybrid organic-inorganic materials Zn-2-Cr and Zn-2-Al-LDHs (Layered Double Hydroxides) containing 4-(1H-pyrrol-1yl)benzoate anions as the interlayer anions were synthesized by the co-precipitation ...
New layered double hydroxides intercalated with substituted pyrroles. 2. 3-(Pyrrol-1-yl)-propanoate and 7-(pyrrol-1-yl)-heptanoate LDHs
(Elsevier B.V., 2006-05-01)
We report the synthesis and characterization of organic-inorganic hybrid materials: Zn-2-Al-LDHs (layered double hydroxides) containing 3-(1H-pyrrol-1-yl)-propanoate and 7-(1H-pyrrol-l-yl)-heptanoate as the interlayer ...
Structural Characterization of Rare-Earth Doped Yttrium Aluminoborate Laser Glasses Using Solid State NMR
(AMER CHEMICAL SOC, 2009)
The structure of laser glasses in the system (B(2)O(3))(0.6){(Al(2)O(3))(0.4-x)(Y(2)O(3))(x)} (0.1 <= x <= 0.25) has been investigated by means of (11)B, (27)Al, and (89)Y solid state NMR as well as Y-3d core-level X-ray ...
Molecular dynamics of poly(Ethylene Glycol) intercalated in clay, studied using 13C solid-state NMR
(MDPI AGBasel, 2013-01)
In this study, Cross-Polarization Magic-angle Spinning CP/MAS, 2D Exchange, Centerband-Only Detection of Exchange (CODEX), and Separated-Local-Field (SLF) NMR experiments were used to study the molecular dynamics of ...
7Li and 29Si solid state NMR and chemical bonding of La2Li2Si3
(ElsevierAmsterdam, 2012-03)
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 ...
Structural similarity on multiple length scales and its relation to devitrification mechanism: a solid-state NMR study of alkali diborate glasses and crystals
(2009)
The nature of the devitrification process is a fundamental problem in glass science and governs the ultimate stability of glass. It is hypothesized that the devitrification mechanism of a given glass composition is strongly ...

Structural studies of NaPO3-WO3 glasses by solid state NMR and Raman spectroscopy
(Royal Soc Chemistry, 2006-01-01)
Vitreous samples were prepared in the (100 2 x) NaPO3-x WO3 (0 <= x <= 70) glass forming system using conventional melting-quenching methods. The structural evolution of the vitreous network was monitored as a function of ...
