Course main content

This course reviews strategies for fabrication of nanostructured functional materials from building blocks with at least one dimension less than 100 nm. It aims at teaching the students a variety of solution based chemical techniques that are commonly used for the fabrication of nanostructured materials. A general introduction on materials chemistry starting from the atomic level to the formation of crystals/solids and crystal structures, intermolecular and intramolecular forces, molecular structures, stoichiometric calculations will be introduced in the beginning. Bottom up strategies for the fabrication of nanostructured materials with a higher flexibility of controlling materials’ microstructure will be emphasized. Solution based techniques will be prioritized in order to emphasize the significance of prior chemical knowledge in making the desired materials. Specifically the following nanomaterials fabrication techniques will be covered: Solution co-precipitation, thermodynamic modeling; sol-gel synthesis; redox reactions and electrochemical synthesis; microemulsion synthesis. Self-assembly, or directed assembly, process, related chemical principles, and its use for the fabrication of higher order nanostructures will be presented. After introducing all these techniques, pros and cons will be discussed and several examples of their implementation in materials science will be presented.
