Educational objectives
- knowledge of the principles that determine the chemical and physical properties of nanostructured materials;
- knowledge of the chemical principles on which the methods for synthesizing nanostructured materials are based;
- knowledge of dimensional and surface effects on the electronic properties of nanomaterials
- knowledge of the dimensional and structural characterization methods of nano materials;

- ability to rationalize phenomena of interest and to describe them on quantitative bases, using the basic principles and models acquired;
- ability to identify the method and experimental conditions suitable for preparing nanostructured composite materials and defined dimensions;
- ability to select the most appropriate analytical technique according to the nature of the object or material to be characterized
- ability to use a technical-scientific language appropriate to the issues being dealt with.
In order to understand the conceptual and know how to deal with the course the student must have knowledge of
- Description of the thermodynamic processes in solution in homogeneous and heterogeneous conditions; Kinetic equations in homogeneous and heterogeneous solutions .
- Chemical bonds; model of molecular orbitals.
- Hydrogen-atom model.
Teaching methods
The course is organized in two parts:
The first part consists of class lectures (for a total of 5 CFUs) on all subjects of the course with the help of video devices.
The second phase consists of three exercises (for a total of 1 CFU) lasting four hours each. The students will be divided into groups (maximum three students per group) and they will carry out practical experiences regarding the design of the preparation method for defined nanomaterials and the of the most suitable dimensional and electronic analysis method.
Other information

Learning verification modality
The evaluation is conducted by an oral exam, which consists of a discussion lasting about 40-45 minutes aimed at ascertaining the level of knowledge and understanding achieved by students on the theoretical and methodological implications mentioned in the program.
The oral exam will also test the communication skills of the student with scientific jargon proper device and the ability to apply theoretical concepts to practical exercises and experiments.
