At the end of the course you will understand the fundamental reasons for the size dependent properties of nanomaterials and will be able to follow the scientific literature in the field.|
More specifically you will have achieved the following goals:
- Understand how the physical and chemical properties of nanocrystalline semiconductors and metals change as a function of the particle size;
- Understand how the size, shape and surface of colloidal nanocrystals can be controlled by chemical preparation methods
- Understand the trends in the physical chemical properties of metal nanoparticles
- Can propose how to characterize a nanoporous or 3D nanostructured material
- Know the most important classes of nanoporous solids and their main characteristics
- Understand how physicochemical properties of gases, liquids and solids are influenced by surface effects and confinement into nanopores
- Are familiar with the applications of nanoporous materials-based systems for sustainable energy applications, focusing on reversible gas storage
- Understand the thermodynamic and kinetic aspects of nanocolloid self-assembly
- Can explain the magnetic and opto-electronic properties of quantum dot superlattices
- Know how quantum- dot solids can be characterized, and what are their (potential) applications.
Nanomaterials are defined as materials with at least one dimension in the range of 1-100 nm. Reduced dimensions (nanoparticles may consist of only dozens or hundreds of atoms) strongly influence the chemical, optical and electronic properties. The physical and chemical properties of nanomaterials are size dependent, making it possible to tune the materials properties by controlling chemical composition, size, and shape of the nanostructures. For example, an originally stable material may become much more reactive; nanoparticles often have another color than the bulk material, specific (opto)electronic and magnetic effects may take place. World leading research in this field is done within the Debye Institute for Nanomaterials Science, most notably on Catalysis, Colloids, and Quantum dots. The special properties of nanomaterials offer opportunities for all sorts of new applications, e.g. in optics and nanoelectronics, energy conversion and storage, and biomedical applications.
After a short introduction to the field, the following topics are discussed in depth:
Semiconductor and metal nanoparticles (C. de Mello-Donegá) (24 contact-hours distributed over 6 days)
Nanoporous materials and supported nanoparticles (P.E. de Jongh) (24 contact-hours distributed over 6 days)
Self-assembled quantum-dot solids (D.A.M. Vanmaekelbergh) (24 contact-hours distributed over 6 days)
