Different iron oxide structures were formed by annealing of iron foils in air at temperatures between 500 °C to 800 °C. Depending on temperature, a significant variation in the hematite/magnetite ratio and a strongly temperature dependent morphology is obtained. While over a wide range of conditions more or less compact Fe3O4/Fe2O3 layers are obtained, at 600 °C rapid growth (several micrometer per hour) of highly crystalline hematite nanowires

An encapsulation of a liquid phase in a thin poly(methyl methacrylate) (PMMA) membrane is achieved in one step by pulsed direct liquid injection (DLI)CVD. The polymer thin film is grown by photo-activation of the gas phase. An original step of the process, described as thermally induced release of internal liquid phase, permits control of the encapsulated liquid during the CVD polymerization. This step highlights a phenomenon that facilitates a conversion
