Analytical Chemistry

The Course includes 6 CFU, 5 of frontal teaching and 1 of practical activities, divided into the following general topics: general characteristics of materials and nanomaterials (12 h), characterization techniques for polymeric materials and nanomaterials (18 h), chemistry of nanostructured materials and their applications (18 h). Detailed program of the course: in the following section the program with the relative articulation over time is illustrated in detail. The course includes a total of 6 credits and develops in 40 hours (5 CFU) of frontal teaching with constant involvement of the students and 12 h (1 CFU) of practical activities. The course is articulated as follows: • Materials of inorganic, polymeric and hybrids, introduction on nanoscience and nanomaterials (6 h) • Understanding nanosystems (6 h) • Experimental methods of investigation of polymeric materials and nanomaterials (12 h) • Synthesis and characterization of nanomaterials of organic, inorganic, synthetic and natural origin (12 h) • Advanced nanomaterials and some examples of nanotechnology applications (4 h) • Laboratory experience on polymeric materials and nanomaterials characterizations (12 h)

The Chemistry of Nanostructured Materials course is in the Master Degree of Analytical Chemistry, in the first year, second semester. Some basic preliminary knowledge is indispensable, in particular those deriving from the three-year courses of General and Inorganic Chemistry, Organic Chemistry and Physical Chemistry, such as the ability to describe the reactivity of functional groups, use of stoichiometry, kinetics and thermodynamics.

The frequency of teaching classes is not mandatory but recommended.

The achievement of the learning outcomes is ascertained with an oral exam, in which the student is asked to describe what has been learned in the course, also with examples. The exam aims to verify the level of knowledge and in-depth examination of the topics of the teaching program and the reasoning skills developed by the student. The evaluation is expressed in thirtieths (minimum grade 18/30, maximum mark 30/30 with honors). The evaluation consists of an oral test. The overall exam allows to verify the achievement of the objectives in terms of knowledge and skills acquired as well as communication skills. The timing of the exam will be at the end of the course and in the sessions provided by the CAD (June-July, September, January-February) The exam includes open-ended questions on the topics covered in the course, accompanied by examples. The answers are evaluated for completeness of content, ability to synthesize and links between the different themes developed during the course. The examples are useful to verify the ability to interpret the structure and reactivity of the macromolecules. In the assessment of the examination the determination of the final grade takes into account the following elements: the theoretical basis followed by the student for the exposure of the question, the ability to reason, the property of language, the clarity of exposition and critical ability. To pass the exam, the student must demonstrate that he has acquired sufficient knowledge of the topics concerning the topics of this course. To achieve the maximum score (30/30 cum laude), the student must demonstrate that he has acquired an excellent knowledge of all the topics covered during the course, being able to link them in a logical and coherent way, with a correlation capacity between the chemical structure and properties. Students will also be offered current topics from recent literature, to be developed and proposed as an oral exam.

The course is structured in frontal theoretical lectures with the illustration of numerous examples to demonstrate and apply the theoretical aspects exhibited. In particular, a total of 40 hours of frontal teaching (5 CFU) are planned to acquire the knowledge highlighted in the training objectives, together with 1 CFU (12 h) of practical work. In order to develop the ability to apply knowledge, examples are provided, also taken from the recent literature, in order to stimulate students' critical skills in the field of new materials. The lessons are held weekly in the classroom, with two lessons each two hours, for a total of 4 hours per week and the exposure is done using the blackboard and / or slides on power-point. The frequency of teaching classes is not mandatory but recommended.
