Obiettivi dell'insegnamento

The course is an introduction to the physics of soft materials, complex fluids, and biological systems, ranging from simple colloidal suspensions to polymer, spontaneous surfactant aggregates, gels, proteins and nucleic acids. Besides providing a bottom-up presentation of the properties of complex fluids, based on their microscopic structure and interactions, the course aims to highlighting the important role played by these materials in the consumer market and for nanotechnologies, focusing in particular on those applications that require an adequate knowledge of their flow and rheological properties.


Risultati di apprendimento attesi

At the end of the course, students should

  • Master the fundamental ideas of soft matter physics and fully grasp those general concepts allowing a wide class of different materials to be investigated using unifying models and methods.
  • Manage to apply the former general concepts to topics of interest in materials science, focusing in particular on recent advancements in disperse systems of   
  • Be capable of conveying the knowledge they have acquired with plainness but also with accuracy and the ability to synthetize a subject.  

Argomenti trattati

1)            General introduction to disperse systems and supramolecular systems. Elements of statistical thermodynamics. Dilute suspensions and osmotic pressure. Effective forces between dispersed particles: excluded volume, van der Waals and electrostatic interactions, depletion forces. Brownian motion.

2)            Colloidal dispersions. Stability of a suspension of colloidal particles and colloidal aggregation.  Colloidal crystals, glasses and hydro/aerogels. Patchy particles. Active colloids. Applications of nanofluids in nanotechnology.

3)            Polymer solutions. Dilute solutions and polymer coils. Semi-dilute solutions, polymer meshes, and Flory-Huggins theory. Polymer gels. Polyelectrolytes.

4)            Surfactant solutions and Emulsions. Classes of surfactant and their practical applications. Micellization and basic principles of detergency. Self-assembly of surfactant molecules: micelles, “living polymers”, inverted micelles, and vesicles. Emulsion stability. Micro and Nano Emulsion. Pickering Emulsions.

5)            Rheological Measurements and Properties of complex fluids. Shear Thinning and Shear Thickening in hard sphere systems. Rheological properties of polymer networks and surfactant solutions  Rheology and plasticity of gels and glasses.

6)            Experimental methods to investigate soft materials. Light Scattering, correlation spectroscopy, video microscopy, and microfluidics techniques (with lab presentations). Macro and micro-rheology.


Prerequisiti

To attend the course a solid knowledge of elementary classical physics and a discrete mastering of calculus are required. To fully appreciate all the subjects presented in the course, some notions of statistical physics may also be useful, although not strictly necessary since a short review of its basic concepts will preliminarily be provided by the teacher (see Topics 1 above).


Modalità di valutazione

The evaluation consists in an oral examination, structured so to ascertain whether and to what extent the goals of the course have been reached. During the exam, the student is first required to discuss by means of a short Power Point presentation a specific review article concerning one of the topics taught in the course, chosen among a list of papers uploaded by on the Beep portal, so to check her/his skills in summarizing and framing an argument.  Mastering of the acquired knowledge is then verified by asking the student to focus on some of the key physical ideas used in that paper and on a current application of the discussed argument.  For the overall evaluation, a yardstick of the student’s performance, besides the clarity and effectiveness of the exposition, will also be the skill in using an appropriate scientific language and the readiness in finding connections between different topics.

Note:

This is not a textbook, but rather a popoular science book written in a plain language and accessible to a large audience. Yet, it contains most of the physics we need

Risorsa bibliografica facoltativaCoussot, Philippe, Rheophysics, Editore: Springer International Publishing, Anno edizione: 2014, ISBN: 978-3-319-38016-2
Note:

This book presents a unified view of the physicochemical origin of the mechanical behaviour of soft materials.The mathematical formalism is reduced in order to focus on physical explanations.
