65942 - Applied Chemistry and Materials Science

Learning outcomes

Material Science - 6CFU Chemical and Mechanical Engineering

This course provides a general introduction to the classification of materials describing their main physical, chemical and mechanical characteristics. It should provide the tools to understand the different behaviour of materials to optimize their selection in different industrial applications.

Applied Chemistry - 3 CFU Chemical and Mechanical Engineering

This part describes the general chemical characteristics of waters and the chemical and physical composition of crude oil and its derivates. The main water tretments are decribed. The main process on oil fractions are described.

Assessment methods

Achievements will be assessed by the means of a final written exam. This is based on an analytical assessment of the "expected learning outcomes" described above. In order to properly assess such achievement the examination is composed of a written test, duration (1 hour according to the CFUs), composed of (Material Science) 5 multiple choice questions on the theory and two open questions, and a 5 multiple choice test and one open question or exercise (Applied Chemistry).

Aim of the test is to verify the ability of the student to describe the different behaviour of the different materials according to their composition and microstructure. (Materials Science)

Aim of the test for Applied Chemistry is to assess the ability to 1) evaluate the characteristics of waters according to their final use and the effect of the different treatments on water chemical parameters 2) correlate oil-derived products behaviour to the chemical composition

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.

To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.
