Aerosol Generation, Nanoparticles and Nanomaterials, Lectures

After taking the course, the student possesses knowledge of how aerosol routes can be used to generate nanoparticles and fabricate novel nanomaterials. The student understands performance of aerosol reactor design, aerosol generation mechanisms, intraparticle processes, deposition processes of aerosol particles and principles of how to synthesize functional nanomaterials and nanostructures via aerosol routes. The student will also be capable to evaluate and tailor the essential physicochemical properties of the generated nanoparticles choosing appropriate methods and tuning their parameters.

Aerosol reactor design. We will cover the main principles of operation of reactors, chambers and flow systems which are most frequently used when using aerosol processes.

· Batch reactors

· Tubular reactors

· Tank reactors

· Open processes

Aerosol generation mechanisms. The fundamental physical mechanisms on which the aerosol generation methods are based on.

· Mechanical

· Thermal

· Electrical

Intraparticle processes. For material synthesis, understanding and control of the material properties is important. In material synthesis via aerosol route, one of the main challenges is to understand the intraparticle processes which lead to different final morphologies and surface properties of the nanomaterial.

· Agglomeration

· Coalescence

· Morphology

Aerosol particles vs surfaces. In many applications, the aerosol particles are collected/deposited on surfaces. Therefore, knowledge on the physical and chemical phenomena affecting the deposition is important.

· Adhesion

· Bounce

· Deposition processes

Aerosol synthesis and nanomaterials. Here we cover the main processes on how the nanomaterials are fabricated in real industrial processes. Different technologically important examples will be covered. Essential classical journal papers will give and addition to the industrial relevance of the topic.

· Aerosol processes & CVD

· Material synthesis via aerosol route

· Applications
