With a view to extending the comprehensiveness of the International Zeolite Association Database of Zeolite Structures, this paper reports initial efforts to incorporate solid-state nuclear magnetic resonance (NMR) spectra in the database. A collection of 51 Si solid-state NMR spectra of pure silica...
crystallization process. Important correlations between structure- directing templates and the resulting zeolite material have been made, and experimentally motivated hypotheses about the fundamental nucleation events have been put forward. A complete understanding of the crystallization pathway, however, ...
Sorption was found not to depend on the Si/Al ratio because of the stronger effects of zeolite structure and solvent properties. Lastly, in regard to the solute material group, no dependence was found on the investigated zeolite characteristics; the higher the polarity of the solute and the ...
zeolite phases as a function of temperature. The validity of the database is ascertained by comparing newly-constructed equilibrium activity diagrams with experimental observations of zeolite formation during glass dissolution across conditions encompassing diverse solution chemistries, pH’s, and temperatures...
In this work we provide a list of 256 crystal entries in the Inorganic Crystal Structure Database that have errors, incomplete information, or are given the generic name "zeolite" when they may belong to a different family of crystals.关键词: inorganic crystal structure inorganic database materia...
of 15g/L and with degree of 90℃. If the egg shell powder is used as the catalyst, the conversion of lactulose is 18%-21% in 120min with the addition of 12g/L and degree of 96 ℃. Although zeolite, sepiolite, eggshell powder and oyster shell powder are used as catalyst, the ...
N,N-Dimethylpropionamide has been used in the preparation of AST-type zeolite with a plate morphology. N,N-Dimethylpropionamide is strong donor solvent and coordinate to metal ions through the carbonyl oxygen atom. [General Description] Solvation structure of the zinc (II) ion inN,N-dimethylprop...
The Crystallography Open Database (COD, http://crystallography.net/) is as of the time of writing the largest open-access collection of mineral, metal organic, organometallic, and small organic crystal structures, excluding biomolecules that are stored s
