Objectives

Part I (INDUSTRIAL CHEMISTRY)
Knowledge and understanding: the course aims to provide the basic knowledge and understanding related to industrial chemistry with particular reference to thermodynamics, kinetics, catalysis, reaction mechanisms, the knowledge of which is fundamental for the realization and the conduction of chemical and biotechnological processes applied to industry for a sustainable development.
Applying knowledge and understanding: students will be able to apply their knowledge and understanding in the management of industrial biotechnology processes, to perform material and energy balances for simple processes and to solve elementary problems of heat exchange.
Making judgments: students will be able to independently gather and interpret scientific data derived from laboratory measurements and to conduct an experiment with the quantification and evaluation of the results.
Communication skills: students will be able to conduct experiments as a team and to write a report on the laboratory activities using the word and/or graphics processors and the most common spreadsheet programs.

Part II (ENZYMOLOGY)
The course provides advanced knowledge on the applications of enzymes in the industrial fields.
At the end of the course, the students should be able to discern practical conditions for enzyme application in several biotech fields.

Prerequisites

Part I (INDUSTRIAL CHEMISTRY)
The students must have good basic knowledge of General Chemistry, Organic Chemistry and Physical Chemistry. In particular: equations balancing, stoichiometric calculations, concentration of solutions; the main functional groups in organic chemistry and their reactivity; chemical thermodynamics (free energy, enthalpy, entropy); kinetics of chemical reactions.

Part II (ENZYMOLOGY)
Strong basis of Organic Chemistry and Biochemistry.

Teaching Methods

Part I (INDUSTRIAL CHEMISTRY)
The course includes 32 hours of lectures and 24 hours of numerical exercises and laboratory experiments. Lectures are in Italian.

Part II (ENZYMOLOGY)
40 hours of classroom lectures supplemented by slide projection; then laboratory practicals and computer training.


***Teaching will be delivered simultaneously both in presence and online, thus outlining a mixed teaching that can be followed in university classrooms but also remotely. At the beginning of the semester, each student can opt, with a binding choice, for teaching in presence or distance. Depending on the availability of the classrooms and the number of students who opt for the attendance mode, there may be a shift for actual classroom access.***

***As for the laboratory activity, on the basis of the conditions linked to the Covid-19 pandemic, online shifts and/or replacement activities may be envisaged. ***

Verification of learning

Part I (INDUSTRIAL CHEMISTRY)
The final exam is an oral test, which students access only after delivering the reports on the laboratory experiments and taking a written test (minimum mark 15/30, obtained no longer than a year before the oral test). The reports must be delivered within one month after the end of the course, and in any case at least 15 days before the date of the oral exam. The written test, scheduled about a week before each oral exam session, consists of numerical exercises about: conversion, selectivity, yield, atom economy, atom efficiency and E-Factor of a reaction; material balance; heat transfer. During the oral test, the reports on the laboratory experiments and the written test are analyzed and discussed, and various topics covered during the lessons are addressed.
The mark for the Industrial Chemistry part, expressed in thirtieths, takes into account:
-the evaluation of the activity (participation, precision, collaboration, skill) of each student in the laboratory (10%)
-the evaluation of the exercises and laboratory reports (20%)
-the mark of the written test (20%)
-the mark of oral test (50%)

Part II (ENZYMOLOGY)
Examination has the form of a colloquium. Intermediate written tests are possible to assess ongoing learning ability.
Examinations are aimed to a correct and unbiased evaluation of the preparation degree reached by students, i.e. the achievements of the formative targets required in the course.
The examination is an individual colloquium, also requiring the use of graphics, equations, schemes, flux diagrams. The mark is expressed in thirtieth.

The FINAL OVERALL MARK is the average of the marks reported in the two parts.
The evaluation can be:
Insufficient
Very few lessons learned. Incapacity of simple conceptual connections. Insufficient expressive skills:
Sufficient (18-20)
Modest, but still sufficient, capacity to support a coherent dialogue. Few lessons learned, superficial level, many gaps, and elementary conceptual connections. Graphic expression rather stunted;
Fair (21-23)
More expressive skills than sufficient to support a coherent dialogue. Acceptable mastery of scientific language. Discreet acquisition of notions, but little depth, some gaps, and conceptual connections of moderate complexity. Acceptable graphic expression capability;
Good (24-26)
Satisfactory expressive skills and significant mastery of the scientific language. Baggage of rather broad, moderate insight, with little gaps. Dialogical capacity and critical spirit well-perceived. Graphic expression capability more than acceptable;
Great (27-29)
Remarkable expressive abilities and a high level of mastery of scientific language. Baggage of very extensive, thorough knowledge, with marginal lacks. Significant dialogic capacity, good competence, and considerable aptitude for logical synthesis. High graphic expression capability;
Excellent (30)
High expressive skills and a high level of mastery of scientific language. Baggage of very extensive and in-depth knowledge, any irrelevant gaps. Excellent dialogic capacity, a strong ability to make connections between different topics. Great acquaintance with graphic expression.
Honors (“Lode”) are given to candidates well above the average, and whose possible expressive, notional, conceptual, and logical limits appear to be totally irrelevant.

***Based on the conditions linked to the Covid-19 pandemic, the written tests (both intermediate and final) may be replaced by different examination methods.***
