OVERVIEW

This teaching provides the fundamentals required to understand the science of formulations and its increasingly importance in the global economy. The development of formulation technologies involves specific skills and a science-based approach that focuses the contribution of each formulation component in achieving the functionalities requested in the final product.

AIMS AND CONTENT

LEARNING OUTCOMES

This course is aimed to provide an overview on the chemistry of the formulations by means of different topics: recall of the basic knowledge, study of preparation methods and experimental investigation techniques and discussion of management issues. Particular attention will be paid to colloidal systems as an essential component in the formulation technology for advanced industrial applications.

AIMS AND LEARNING OUTCOMES

The main contents of this teaching are related to the knowledge of properties, methods of preparation and characterization techniques of different types of colloids, monolayers and multilayers with the aim to correlate structure and properties of different molecular architectures. To this purpose, specific examples in various application areas are provided. At the end of the teaching the student will be able to:

  • define the application areas and industrial relevance of the chemistry of formulations;
  • describe the properties of colloids, monolayers and multi-layers and their application potential in the field of industrial formulations;
  • identify the most suitable experimental techniques for the characterization of colloids, monolayers and multilayers in relation to their potential applications in the field of industrial formulations;
  • express himself with adequate terminology in the description of phenomena and processes involving colloidal systems and formulations.

PREREQUISITES

No official pre-requisites are required. However, it id recommended to have attended the lectures of the teaching "Colloids and Interphases".

Teaching methods

The teaching consists of traditional lectures for a total of 32 hours, sometimes accompanied with exercises carried out by the teacher in the classroom. Lesson notes are uploaded to the corresponding AulaWeb page simultaneously with the presentation of their content in the classroom.

In order to facilitate the individual preparation, verification tests are uploaded to the corresponding AulaWeb page.

SYLLABUS/CONTENT

Recalls on the formulation chemistry: areas of application and industrial relevance.

Recalls on the science of colloids and surfaces and its role in the formulation chemistry.

Colloids: molecular, structural and electronic properties. Quantum confinement effects and their importance in conditioning the properties of the matter at the nanoscale level (optical, magnetic, mechanical) and reactivity.

Transport properties of colloidal systems: diffusion, sedimentation and membrane equilibria (osmotic pressure, Donnan effect, dialysis processes). Examples of applications on biological macromolecules.

Rheological properties of colloidal systems: Newtonian and non-Newtonian fluids (plastic, pseudo-plastic, dilatant fluids). Einstein's theory on the viscosity of dispersions. Thixotropy and anti-thixotropy. Rheometers and viscometers. Examples of applications in cosmetics and food industry.

Association Colloids: general properties, critical micellar concentration, thermodynamics and kinetics of micellization. Structural models for micelles dispersed in water and definition of the corresponding structural parameters. Solubilizing, detergent and catalytic properties of micelles and their applications. Reverse micelles, liposomes and lyotropic liquid crystals: structure, properties and applications.

Formation of monolayers and multilayers by adsorption from solutions. Self-assembled monolayers on solid substrates (SAM): structure, properties and methods of preparation on 2D- and 3D-surfaces. Langmuir-Blodgett films: structure and properties. Examples of applications of adsorbed monolayers and multilayers.

EXAMS

Exam description

The exam is an oral examination conducted by two teachers for a duration of at least 30 minutes. During the calendar year, seven exam dates are set up within the time intervals scheduled by the Manifesto degli Studi.

The oral examination usually consists of two parts; both of them are awarded a maximum rating of 15/30 for the exam evaluation:

- in the first part, the student has to face a problem connected to formulation chemistry in order to verify his understanding and mastery of the teaching topics as well as his ability to apply the theoretical concepts to real situations;

- in the second part, the student is called upon to answer two questions related to different topics of the teaching program, chosen by the examination committee; the second part is awarded a maximum rating of 15/30.

Assessment methods

Goal of the assessment is to verify the understanding and mastery of the learning outcomes by the student, particularly as far as the student’s ability to correlate the properties of colloids, monolayers and multilayers to their potential applications in the field of industrial formulations is concerned. Otherwise, the student is invited to deepen his preparation also by taking advantage of further explanations by the teacher before repeating the exam.

Moreover, the oral exam will avail to verify the achievement of the appropriate level of knowledge of the topics transmitted during the lectures and the language skills. The student's ability to compare and integrate the data available from various experimental characterization techniques and from the correlation structure-property models included in the teaching program will also be evaluated.

As a quality assurance, the detailed program of the teaching is uploaded to the corresponding AulaWeb page, so that students can verify the correspondence between topics and learning outcomes.
