Synthesis of Monodisperse Nanocrystals of Manganese Oxides
Abstract
We report a simple and effective method for the generation of high-quality nanocrystals of manganese oxide, MnO, with an alkyl capping group. MnO is a model system for the theoretical study of electronic and magnetic properties of rock salt oxides. Synthesis of relatively monodisperse nanocrystals of MnO was achieved over a range of sizes between 7 and 20 nm. The nanocrystals are readily dispersed in nonpolar solvents, and their uniformity allows for the formation of superlattices, as observed by TEM. Fitting size evolution/time data with the Lifshitz-Slyozov-Wagner model indicates that the increase in particle size from 7 nm is dominated by diffusion-limited growth. Controlled chemical oxidation can allow for the preparation of nanocrystals of Mn3O4 from MnO. We demonstrate the use of acetate precursors in the preparation of ligand-capped, transition metal oxide nanocrystals (of MnO and FeO), which are safer and more environmentally benign than their metal carbonyl counterparts.

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.
