Single and geminal hydroxyl species in silicas have been characterized using solid-state (29)Si NMR spectroscopy. Differentiating hydroxyl types is important in understanding their roles in chemical toxicity mechanisms for inhaled crystalline silicas

Longitudinal multispin orders can be created in spin systems that exhibit scalar, dipolar or quadrupolar couplings. They provide an effective way for measurement of scalar couplings and also to probe molecular interactions and dynamics. They cannot b

Because of their small size, the specific surface areas of nanoparticulate materials (NP), described as particles having at least one dimension smaller than 100 nm, can be large compared with micrometer-sized respirable particles. This high specific

The many roles of alkali metal−oxygen phases as catalyst components and promoters motivated a survey of the NMR properties of these compounds. Solid state 7Li, 23Na, 39K, 87Rb, and 133Cs magic angle spinning NMR spectra are reported for the followi

The preparation of CFx by elemental fluorination of charcoal was studied using solid state 13C and 19F NMR spectroscopy. 19F−13C CP/MAS NMR experiments determine the extent of fluorination vs reaction temperature. Three types of carbon species obse

Proximal sites consisting of a divalent metal cation as a hydroxide and/or oxide and an anion site in the zeolite framework are very active for the conversion of methyl halides to ethylene. These studies further support the effects of zeolite framewo

It is shown that methyl halides (I, Br, Cl) react to form ethylene and other hydrocarbons on basic, alkali metal-exchanged zeolites at low temperatures. For example, methyl iodide is converted to ethylene on CsX zeolite at ca. 500 K. The order of rea
