| Contents | Comprehension of both Natural and Computational Complexity. Foundations of Non-Equilibrium Thermodynamics and Non-Linear Dynamics. Oscillating chemical reactions. Chaos and Fractals. The students will carry out four laboratory experiments to experience the principles of the Non-Equilibrium Thermodynamics and Non-Linear Dynamics. |
| Reference texts | P. L. Gentili, “Untangling Complex Systems: A Grand Challenge for Science”, CRC Press, 2018, ISBN 9781466509429. |
| Educational objectives | The graduate students in Chemical Science learn the principles of the Out-of-Equilibrium Thermodynamics and Non-Linear Dynamics only in “Complex Systems Investigation”. This course's primary purpose is to give the students the conceptual and methodological basis to face the interdisciplinary analysis of Complex Systems. The central notions that must be learned by students are: •evolutive criteria of the physical and chemical systems in out-of-equilibrium conditions; •self-organization; •deterministic chaos and fractal structures; •Natural and Computational Complexity. All these notions will allow students to: •predict the evolution of out-of-equilibrium systems; •experimental investigation of the self-organizing chemical and physical systems; •appreciate the limits of science in predicting the behavior of deterministic chaotic systems; •characterize Fractal structures. |
| Prerequisites | Knowledge of the Equilibrium Thermodynamics. |
| Teaching methods | The course is organized in two stages. The first stage consists of the frontal lessons proposed in the classroom and regarding all the subjects of the course. It is assisted by short movies extracted from the web. The second stage consists of four experiments requiring six hours each. The experiments will be carried out in the Photophysics and Photochemistry Laboratory of the Chemistry, Biology and Biotechnology Department. Students are split into groups (having no more than three members) and perform the experiments in parallel by using distinct facilities available in the Laboratory. |

| Learning verification modality | The acquisition of the course topics is tested in two ways. A written test that consists of writing the reports of the laboratory experiences. An oral exam with questions related to the subjects presented during the lectures. The Professor must receive the students’ reports of the laboratory experiments before taking the oral test. |
| Extended program | The subjects proposed are 1) Introduction to the Natural Complexity and the Science of Complexity. 2) Deepened analysis of the II Law of Thermodynamics. 3) Non-equilibrium Thermodynamics. Flows and Forces. Linear and Non-Linear regimes. Entropy Production and evolution criteria for the out-of-equilibrium systems. 4) Linear analysis of the stability of the stationary states: stable, unstable, and oscillatory stationary states. 5) Oscillatory chemical reactions, chemical waves, Turing structures. Periodic Precipitations. 6) More insight on the Non-Linear regime: Bifurcations and deterministic Chaos. The case of convection. 7) Fractals. 8) Natural and Computational Complexities. Strategies to face Complexity Challenges. Four experiments involving out-of-equilibrium systems are carried out in the laboratory. |

| Contents | The course examines the non-reactive liquid processes in the liquid phase, using light scattering spectroscopy. Rotational, vibrational and translational degrees of freedom are examined, using the formalism of time correlation functions. Calculation and interpretation of dynamic parameters have been done through hydrodynamic and diffusive and stochastic models. Finally, some kinds of samples of biological interest are studied, linked to biomedical issues, always using light scattering techniques, coupled with micro sampling. |
| Reference texts | B.B. Berne, R. Pecora, Dynamic Light Scattering - with applications to Chemistry, Biology and Physics, Dover Publications INC, Mineola NY given by the prof.: scientific articles, text of laws, chapters of books |
| Educational objectives | The main objective of the course is to provide students with the bases needed to address the study of dynamics in molecular liquids, through spectroscopic light scattering techniques. Fourier Transform mathematical tool allows to go from the frequency domain to the time domain, and vice versa, thus using different formalism and parameters, linked to different domains, and often complementary in order to obtain a complete dynamic picture of the molecular system examined. |
| Prerequisites | Basic elements of molecular spectroscopy |
| Teaching methods | Frontal lessons, laboratory exercises |

| Learning verification modality | evaluation of laboratory reports, oral examination |
| Extended program | Continuous and discrete Fourier transforms: definitions and main theorems. Formalism of correlation functions. Light scattering theory. Polarization properties of light. Experimental geometries. Elements of hydrodynamics. Rotational dynamics through diffusion models: Stokes Einstein Debye model. Spectroscopic techniques for the study of rotational dynamics, and related dynamical parameters. Vibrational dephasing and Kubo model. Brillouin spectroscopy. Confocal microscopy and optical fibers. Cryopreservation. Physico-chemical properties of molecular membranes. |
