Structural models for yttrium aluminium borate laser glasses: NMR and EPR studies of the system (Y(2)O(3))(0.2)-(Al(2)O(3))(x)-(B(2)O(3))(0.8-x)
(ROYAL SOC CHEMISTRY, 2011)
The structure of laser glasses in the system (Y(2)O(3))(0.2){(Al(2)O(3))(x))(B(2)O(3))(0.8-x)} (0.15 <= x <= 0.40) has been investigated by means of (11)B, (27)Al, and (89)Y solid state NMR as well as electron spin echo ...
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 ...
Polynitroxides from alkoxyamine monomers: structural and kinetic investigations by solid state NMR
(American Chemical Society - ACSWashington, DC, 2013-04)
A novel synthetic route toward poly(4-methacryloyloxy-2,2,6,6-tetramethylpiperidine- N-oxyl) (PTMA) is described. The polymerization of alkoxyamine-based monomers by atom transfer radical polymerization (ATRP) was investigated, ...
Micromorphology and spectroscopic characteristics of organic matter in waterlogged podzols of the upper Amazon basin
(Elsevier B.V., 2008-06-15)
In waterlogged environments of the upper Amazon basin, organic matter is a major driver in the podzolisation of clay-depleted laterites, especially through its ability to weather clay minerals and chelate metals. Its ...
