General Objectives: The course aims to provide an overview of functional nanostructured materials, their properties, their synthesis, their main characterization techniques and applications, in particular in the environmental, biomedical and cultural heritage fields. Furthermore, the aim is to provide basic knowledge on Electron Microscopy and thermal analysis techniques and their main applications.
Requirements: Basic knowledge of: i) physical chemistry of the solid state iv) X-ray diffraction
- nanomaterials and nanotechnologies;
- the new chemical and physical properties associated with the nanoscale;
-synthetic strategies;
- characterization techniques useful for observing the nanoscale;
- transmission electron microscopy;
- thermal analysis;
- new applications in different fields (environmental, biomedical and cultural heritage).
- identify the peculiarities of nanostructured materials;
- identify the fundamental steps of a synthesis of a nanostructured material;
- identify the synthesis techniques suitable for the specific application;
-correlate the information obtained from the different techniques.
The student must be able to interpret the experimental results obtained by developing a good critical sense in the optimization of synthetic methodologies for the specific application, in interpreting electron microscopy and thermal analysis data and correlating them with those obtained by other techniques .
The experience on synthesis, the multi-technical characterization phases and the final presentation will offer the student the opportunity to evaluate and verify the knowledge acquired and to develop his critical sense.

The course aims to develop the ability to present in a synthetic and exhaustive way a new topic such as that of nanostructured materials also through the use of computer media (PowerPoint presentations).

Each topic will be treated first from a theoretical point of view, then it will be developed practically through laboratory experiences and the results obtained will be discussed together in class. This approach should develop in the student the ability to interconnect andand thus learning.


Batchelor degree in Chemistry, material science or physics.
Basic knowledge of: i) solid state physical chemistry; ii) X-ray diffraction; iii) FT-IR;

The characterization of the materials includes the phases of sample preparation, analysis and data processing with different software.

Teaching Methods

The course is organized into:
1) oral lessons (16 hours),
2) preparatory lessons to experimental experiences and laboratory and data analyses (48 hours).
Due to COVID-19 emergency, on-line lessons and data analyses will be provided. Multimedia tools (computers, projector, movies and animated simulations), traditional (blackboard) and participatory learning will be used.

Verification of learning

The overall evaluation of the student takes place on the judgment of power point presentation on a topic assigned by the teacher, and an oral exam.

Consequently, the judgment can be:
The knowledge of the topics of the course, the ability to link between different topics, the expressive capacity, the use of appropriate terminology, the ability to synthesize, will be evaluated.

Final Judgement. The final mark takes into account several factors:
a) appropriateness, accuracy and consistency of knowledge
b) appropriateness, accuracy and consistency of skills
c) expressive capacity;
d) proper use of the specific language of the discipline;
e) logical and consequential capacity in the fitting of the contents;
f) Ability to connect different topics by finding common points and establishing a coherent overall design, that is taking care of the structure, organization and logical connections to the exhibition's speech;
f) synthesis capacity including through the use of its symbolism of matter and the graphic expression of ideas and concepts, for example in the form of formulas, diagrams, equations.

Relational qualities:
Availability to exchange and interaction with the teacher during the classes and the oral exam.

Personal qualities:
a) critical spirit;
b) self-assessment ability.

Consequently, the judgment can be:
30 cum laude The power point presentation on an issue assigned by the teacher and the oral exam is precise and rich of details. The student has demonstrated strong critical sense. Skills, independent judgment, communication skills and learning ability are excellent.

28-30 The power point presentation on an issue assigned by the teacher and the oral exam are very good. The student has demonstrated a good critical sense. Skills, independent judgment, communication skills and learning skills are very good.

25-27 The power point presentation on an issue assigned by the teacher and the oral exam are good, with some imprecisions on certain aspects. Skills, independent judgment, communication skills and learning skills are good though not particularly rich in detail.
22-24 The power point presentation on an issue assigned by the teacher and the oral exam are quite good but with some inaccuracies of some argument. Skills, independent judgment, communication skills and learning skills are adequate despite some uncertainty.
18-21 The power point presentation on an issue assigned by the teacher and the oral exam are sufficient with several inaccuracies on different topic. Skills, independent judgment, communication skills and ability to learn are sufficient.
