Nanotechnology of Disperse Systems:
This lecture begins with a revision of basic topics in the theory of nucleation, growth and electrostatic stabilization of particulate materials. Following this the challenges and solutions to the problem of metal, oxide, semiconductor and polymer particle synthesis will be discussed. The second half of the course will concern the characterization, properties and application of disperse systems. In addition to understanding the measurement of particle and agglomerate size and shape, the factors affecting the electronic, magnetic, optical and catalytic properties will be covered. Particles are often applied as part of a hierarchical system e.g. in a device, functional coating, drug delivery system. The use of self-assembly and printing/patterning techniques to achieve these goals will be presented with reference to work carried out within the Erlangen Cluster of Excellence "Engineering of Advanced Materials - Hierarchical Structure Formation for Functional Devices". For the associated "Exercises" participants of the course will be required to explore the literature and give a 10 minute presentation regarding recent developments in a specific aspect of disperse systems or nanoparticle research.

Self-Assembly on Surfaces:
The lecture introduces with fundamentals of physisorption, chemisorption, growing modes, chemistry of surface binding via different motifs, analytical method for surface characterization, and nano-phase-separation. We will discuss weak intermolecular and surface interactions (van-der-Waals und dipoles), the mobility of nano-objects on surfaces and their use in 2D and 3D assembly. Medium interaction motifs (H-bonding, other non-covalent motifs) as driving forces. Main task will be the techniques and processes for self-terminating growth, 2D-superstructures according to the substrate and the chemistry. Strong interaction motifs (Coulomb, covalent) will be discussed in terms of stability, the possibility of exchange reactions on surfaces. Finally we will discuss methods to achieve hierarchical structure formation (layer-by-layer, complex layers structures, gradients, patterned structures and self-assembly on complex inner structures. We will conclude with classification and examples of self-assembled systems of 2. - 5. order.

Mechanical Properties and Structures of Advanced Materials:
The mechanical properties play an important role for all kinds of application of advanced and nanostructured materials. Therefore, in this lecture the different aspects of mechanical properties (i.e. strength, fracture, fatigue, creep…) with an emphasis on effects at the nanoscale including the properties of thin films will be discussed. The mechanical properties are closely related with the crystallographic structure and also the microstructure. New advanced materials as bulk metallic glasses and quasicrystals show an interesting mechanical behavior which will be discussed also including other advanced nanomaterials. The lecture will cover the following topics

• mechanical properties of engineering materials

• plasticity and hardening in metals / Strengthening mechanisms

• fundamentals of fatigue

• measuring mechanical properties at the micro- and nanoscale / Nanoindentation

• size effects - thin films and small volumes / Testing at small scales

• deformation and structure of structurally complex materials

• quasicrystals

• bulk Metallic Glasses

• mechanical properties of other advanced materials (e.g. Advanced steels, Metallic nanomaterials)
