Our research theme is inorganic nanosheets. Nanosheets are characterized as freestanding, two-dimensional materials from one to several monolayers thick (<10 nm total) and up to tens of microns in lateral dimensions. The nanosheet morphology has several features that put it at the frontier of materials development, and on a fundamental level, nanosheets provide an opportunity to better understand materials at the ultimate thickness limit—down to a single monolayer. We study a range of prototype material classes with diverse structure types, functional properties, and synthetic challenges. In this talk I will describe our results in two areas: (1) the preparation and chemistry of magnesium diboride nanosheets, which are derived from superconducting bulk magnesium diboride, and (2) the synthesis and structure of ternary oxide nanosheets, AXO3, which include a unique nanosheet form of the bulk ferroelectric material barium titanate.
