Contents After a brief introduction to nano-structured materials and t
classification, the dependence of chemical and physical properties on
dimensionality will be addressed highlighting differences respect to bulk
systems. Examples of nanostructured natural systems will be the
presented. The main part of the course will concern the preparation
methods of nanostructured synthetic systems through chemical methods
with special reference to nanoparticles and nanorods followed by their characterization and applications.

Educational objectives This course is the first of the entire degree program completely focused
on the study of nanostructured systems. The main aim of the course is to
transmit to the student the following knowledges:
- definition of nanostructured system and importance of the dependence
of the properties of the size. Differences with bulk systems.
- thermodynamic and kinetic principles related to the chemical synthesis
of nanostructured systems.
- potential applications of nanostructured systems
The course will provide the student the following skills:
- identification and optimization of experimental parameters for the
synthesis of metal and semiconductor nanoparticles.
- identification of potential applications of nanostructured system
according to their chemical-physical properties.
- identification of parameters to be optimized to increase
performance of a nanostructured system
Prerequisites For a full and easy understanding of the topics of this course it
important to have good basic knowledge of General Chemistry and
Physical Chemistry (thermodynamics, kinetics and UV-
spectroscopy).
Teaching methods The course is organized as follows:
- face to face lectures concerning all the topics covered during the course
using PowerPoint presentations,
- LABORATORY ACTIVITY. preparation of a powerpoint presentation on a
topic agreed with the teacher.
Demonstrative laboratory experiments at the photochemistry an
photophysics laboratories of the Chemistry Biology and Biotechnology
department in via Elce di Sotto
Other information The face to face lectures will be held at the location of the Chemistry
Biology and Biotechnology Department in via del Giochetto edificio B.
The Laboratory experiments will be carried out at the Laboratory o
photochemistry and photophysics of the headquarters of the Department
of Chemistry, Biology and Biotechnology of Via Elce di Sotto 8
Learning verification modality The final exam consists of two tests:
1) oral exam: it consists of an interview long enough to determine and
verify the knowledge level, understanding capability and technical skills
achieved by the student on the topics covered during the frontal lectures
and the analytical techniques used during the laboratory experiences. It
will be tested also the capacity of the student to communicate an
present the theoretical contents with an appropriate scientific language
and the critical sense acquired by the student in dealing with issues
concerning the application of nanostructured systems in medical,
biological , energetic and environmental field.
2) preparation of a powerpoint presentation on a topic agreed with the
teacher. The presentation is aimed to test comprehension by the student
of the issues addressed during lessons and theoretical principles related
to them, and finally the ability to organize contents in written form with
an appropriate vocabulary.
The final evaluation will take into account both the oral test and the
powerpoint presentation.
Students with disabilities and/or DSA are invited to visit the pa
dedicated to the tools and measures envisaged and to agree in advance
with the teacher what is necessary (https://www.unipg.it/disabilita-e -
