Oxygen is a key chemical element and solid state NMR can provide unique insight into the
its local environment. In the last decade there have been significant advances (sensitivity …

The increase in the cement industry's production, especially the production of Ordinary
Portland Cement (OPC), increases the amount of CO 2 released into the atmosphere, one of …

A systematic series of aluminosilicate geopolymer gels was synthesized and then analyzed
using 29Si magic-angle spinning nuclear magnetic resonance (MAS NMR) in combination …

Current needs for extending zeolite catalysts beyond traditional gas-phase hydrocarbon
chemistry demand detailed characterization of active site structures, distributions, and …

We present for the first time, direct and clear experimental evidence of Al–O–Al and Si–O–Si
linkages in charge-balanced aluminosilicate glasses with Si/Al= 1, such as NaAlSiO4 …

We investigate short-range order and local atomic configuration in charge-balanced
aluminosilicate glasses as functions of composition, using 17O and 27Al MAS and triple …

In the past few decades, the increasingly routine use of advanced structural probes for
studying the structure and dynamics of the solid state has led to some dramatic …

Although the solid state is typically characterised by inherent periodicity, many interesting
physical and chemical properties of solids arise from a variation in this, ie changes in the …

A statistical thermodynamic model for the ordering of aluminum-and silicon-centered
tetrahedra in fully condensed X-ray amorphous aluminosilicate network structures is …

We have investigated the Al/Si ordering in the pseudoisolated pairs of tetrahedral sites of the
structure of crystalline gehlenite Ca2Al2SiO7 by means of 29Si and 27Al NMR and first …
