| Learning objective | The students should become familiar with the fundamentals and with application examples of chemically reactive processes in energy conversion (combustion engines in particular) as well as the synthesis of new materials. The lecture is part of the focus "Energy, Flows & Processes" on the Bachelor level and is recommended as a basis for a future Master in the area of energy. It is also a facultative lecture on Master level in Energy Science and Technology and Process Engineering. | ||||
| Content | Reaction kinetics, fuel oxidation mechanisms, premixed and diffusion laminar flames, two-phase-flows, turbulence and turbulent combustion, pollutant formation, applications in combustion engines. Synthesis of materials in flame processes: particles, pigments and nanoparticles. Fundamentals of design and optimization of flame reactors, effect of reactant mixing on product characteristics. Tailoring of products made in flame spray pyrolysis. | ||||
| Lecture notes | Lecture material will be provided | ||||

| 151-0619-00L | Introduction to Nanoscale Engineering | 5 credits | 2V + 1U | S. E. Pratsinis, D. J. Norris, G. Sotiriou, A. Stemmer, A. Teleki Sotiriou | |
| Abstract | The class gives an overview of fundamental concepts in nanoscale engineering. Mobility of small objects, interacting forces, surface tensions and wetting phenomena are some of the physical phenomena investigated. These will be applied to the description of formation and growth of nanoparticles and thin films as well as nanofabrication technologies. | ||||
| Learning objective | The goal of the lecture is to familiarize the students with the basic phenomena occurring on the nanometer scale, thereby illustrating the links to physics, chemistry, materials science, and biology. A further objective is to demonstrate the development of technologies and processes based on or including nanoscale phenomena. | ||||
| Content | - Nanoparticle building blocks for device fabrication - Particle size distributions and size selection - Nanoparticle formation - Forces between small objects - Control of nanoparticle properties in the gas-phase - The electric double layer - Characterization of nanomaterials - Microscopes and tools for nanoscale objects - Thin film formation - Nanofabrication - Small "hands-on" research project including project presentations and reporting | ||||
| 151-0917-00L | Mass Transfer | 4 credits | 2V + 2U | S. E. Pratsinis, R. Büchel, G. Sotiriou, K. Wegner | |
| Abstract | This course presents the fundamentals of transport phenomena with emphasis on mass transfer. The physical significance of basic principles is elucidated and quantitatively described. Furthermore the application of these principles to important engineering problems is demonstrated. | ||||

| 151-0931-00L | Seminar on Particle Technology | 0 credits | 3S | S. E. Pratsinis | |
| Abstract | The goal of the lecture is to convey a basic knowledge in the area of FV materials as well as their construction and production processes and to empower the students to apply the knowledge gained to address current problems in research and practice. | ||||
| Learning objective | Students attend and give research presentations for the research they plan to do and at the end of the semester they defend their results and answer questions from research scientists. Familiarize the students with the latest in this field. | ||||
