Abstract

Nanocrystals of MgO (4 nm) exist as polyhedral structures with high surface concentrations of edge/corner sites. In powder form the crystallites weakly agglomerate into porous weblike structures of approximately 1400 nm according to small-angle X-ray scattering. Upon consolidation of these fine powders under pressure, pellets can be readily prepared that maintain their high surface areas, and small crystallite sizes. In addition, large pore volumes and pore size openings can be controllably decreased with pelletization pressure increase. The pellets retain their voracious adsorbent affinities and capacities for a wide variety of organic molecules and acid gases. Quantitative measurements on the adsorption of a series of alcohols vs pelletization pressure reveal a pattern of molecular size selectivity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
