Master 2 Nanochemistry and Nano-objects
The Nanochemistry and Nanoobjects speciality aims at providing a complete overview from the elaboration to the applications of a large variety of nanoobjects.
The specific core courses are focused on 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 core courses are complemented by a Lab Training period that can be considered as the trademark of the interdisciplinarity of this M2 formation since they will allow the students to explore in situ how nanosystems are studied on UGA. It can be the occassion to have a look at the physical or biological aspects on nanoobjects.
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 Molecular electronics and magnetism broadening course is an occasion to see how magnetic properties are impacted by a drastic reduction in size down to single molecules.
- 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.
By the choice of her/his broadening courses, the students will choose which type of applications she/he wants to focus on.

Goal: To demonstrate the novelty and advances in the field of nanostructured materials and architectured coatings for dedicated functions. Their properties and applications especially in the domain of materials for energy and sustainability will be illustrated.
The different aspects of the bottom-up strategy towards nano-objects will be discussed for the fabrication of nanostructured powders and coatings. Processes using a vapor phase such as Chemical Vapor deposition and Atomic Layer Deposition will be presented in details: principles, applications, technological aspects and modelling. Special attention is focused on multimaterials stability through thermodynamics considerations.

- Specific properties/structure relations (thermodynamical, electrical, catalytic, mechanical properties) of inorganic materials or nanocomposites as powders, ceramics and nanostructured membranes.
- Applications in different high technology domains : energy storage and energy conversion (fuel cells, lithium-ion batteries), environment (catalysis), protection against corrosion, analysis (electrochemical sensors), microelectronics
- Chemical Processing of thin films and 3D nanoobjects from a vapor phase: Chemical Vapor Deposition, Atomic Layer Deposition: technological and chemical aspects (precursors selection), applications
- Modeling of vapor phase processes (thermodynamics, kinetics, Computational Fluid Dynamics)
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.
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.
