An adapted form of vapor transport is used for the preparation of zinc oxide (ZnO) nanostructures. Control of substrate, partial pressure, temperature, and deposition time enable the synthesis of seven ZnO samples, each with different morphology. Cha

Ce(IV) pyrochlore oxides have been prepared by hydrothermal synthesis, and the parent material, a sodium cerium titanate, has been studied using total neutron scattering. While analysis of Bragg diffraction is consistent with an average cubic pyroclo

Time-resolved, in situ XANES studies of some cerium titanate pyrochlores and a fluorite-type bismuth-cerium oxide under reducing and oxidizing gas atmospheres reveal that reduction of cerium occurs at temperature below 500 degrees C in each of the ma

The metastable ilmenite polymorph of NaNbO(3), instead of the expected perovskite polymorph, may be prepared directly in one step under mild hydrothermal conditions by lowering pH and using close to stoichiometric amounts of metal precursors; in situ

We present the results of a study of the solvothermal synthesis of mixed-metal cerium-containing oxides all prepared from CeCl3.7H2O at less than 250 ºC in single step reactions. The use of NaBiO3 in the presence of aqueous NaOH yields fluorite soli

In this critical review we consider the large literature that has accumulated in the past 5-10 years concerning solution-mediated crystallisation of complex oxide materials using hydrothermal, or more generally solvothermal, reaction conditions. The

An investigation of the one-step hydrothermal crystallisation of lithium niobates reveals that reaction between Nb(2)O(5) and aqueous LiOH at 240 degrees C yields materials with a disordered rock-salt structure where the metals are statistically dist
