CHIMICA FISICA DEI SISTEMI BIOLOGICI E DELLE BIOINTERFACCE
Module Principi di Chimica Fisica Biologica (Modulo 1)

Academic Year 2023/2024 - Teacher: Carmelo LA ROSA

Expected Learning Outcomes

The student must learn the quantitative notions and problem-solving of weak forces and interactions, conservation and energy transfers in the form of heat, entropy and thermal machines, chemical equilibrium, phase diagrams, and electrochemistry of reversible processes.

Specifically:

(a) knowledge and understanding skills. The knowledge objective will be achieved by rigorously explaining the basic concepts through the mathematics of differential calculus, integral and differential equations. The goal of understanding the topics covered will be pursued by using examples outside the topics of thermodynamics applied to chemistry, e.g., applications of the laws of thermodynamics to biology and materials in an interactive manner with students.

(b) ability to apply knowledge and understanding. These objectives will be achieved by performing numerical and theoretical classroom exercises of the topics covered.

(c) autonomy of judgment. The autonomy of the judgment test will have been achieved if and only if objectives (a) and (b) are met. If the test is negative, the teacher must take up the unclear topics with new examples and lectures to bridge the remaining lagoons.

(d) ability to communicate. The ability to communicate clearly and rigorously the topics covered will be addressed with lectures at the beginning of the science communication course and a final written test where students expound on a topic covered during the course.

(e) Ability to pursue study independently. This will be achieved and tested at the end of the course using scientific articles related to the program with classroom exposition by students.
