Detailed program - Internship - Testimonials

Introduction

The Nanochemistry and Nanoobjects speciality aims at providing a complete overview from the elaboration to the applications of a large variety of nanoobjects.

First, we will emphasize the elaboration of nanoobjects using the bottom-up strategy. In this approach, the control over the objects’ size, shape and dimensionality is achieved by the choice of the chemical precursors and/or of the reactions conditions such as solvent, pH, temperature, etc...

          

The small size of the objects deserves the use of specific physico-chemical techniques to identify their chemical contents, their size and their properties. These techniques will be described in details.

These first two aspects are so essential to chemists that they will be developed in compulsory courses. They will be complemented by the 2 Lab Training periods that can be considered as the trademark of the interdisciplinarity of this M2 formation since they will allow the students to explore in situ physical and/or biological properties of nanosystems.

Finally, the reduction in size indeed leads to specific physical, mechanical, chemical and biological properties as exemplified below:

  • the nanoobjects allow to finely explore the quantum regime of any physical properties. They are indeed often much different from their classical equivalent;
  • the introduction of nanoparticles in polymers deeply modify their mechanical behavior leading to original composites;
  • in (electro)catalysis, the reduction in size modifies the activity because of both the enhancement of the surface-to-volume ratio and the alteration of the electronic structure of the material;
  • nanoparticles appears as promising candidates for controlled drug delivery for example.

Nanocomposite materials - 3 ECTS

Contact:

 This course will provide background on critical issues in synthesis, fabrication, processing, and characterization of nanocomposites. The major thrust would be the challenges in manufacturing low cost real-life components in industrial applications, commercial success stories, its impact on current established material market, and future directions. We will discuss the underlying scientific principles that guide the study of structure-property relationships and will touch on parallel fields of investigation with high relevance to nanocomposites. The course will also cover the incorporation of a variety of nanophases into polymeric matrixes to provide functional materials, the importance of controlling surface energy, methods for achieving dispersion and common techniques for characterizing nanocomposite materials. The influence of the chemical nature of the dispersed (organic or mineral) elements on the different morphologies observed will be described.

Prerequisites: Introduction to polymer sciences and engineering.

Nano-safety - Management and prevention of a potential risk - 3 ECTS
Contact:

Goal: Nanotechnologies give access to new and interesting properties of materials. Applications or potential applications of nanomaterials are today very numerous in research, industrial processes but also everyday life. As a consequence, impact on health and safety of those new substances becomes important. Indeed, assessment on life cycle analysis is a key element of development. This course presents the current knowledge and research regarding the potential risks associated to the development of nanotechnologies, organized around 3 axes:

  • Toxicology and ecotoxicology current knowledge, thanks to presentation of latest scientific studies on the subject,
  • occupationnal potential risks : how to manage an emerging risk ? what’s mandatory ? what kind of metrology can we use ? what are the best practices in order to prevent impact on health and environment ?
  • social perception of nanotechnologies over the world and over different cultures.
