What do candle flames, medieval stained glasses, fibre
optics and some of the thin-film solar cells have in common? They all contain or utilize nanoparticles. Nanoparticles have a long history;
they are found in wide ranging applications from combustion and alternative
energy conversion devices, air pollution, climate change, catalysis, sensors,
to electronic and biomedical devices. This course will study the theories of
nanoparticle formation, reaction and transport with emphasis on their
applications in combustion, air pollution, and alternative energy conversion
devices. Part 1: Thermodynamics,
transport theories and properties, aerosol dynamics and reaction kinetics of
nanoparticles in fluids. Nucleation, gas-kinetic theory of nanoparticles, the
Smoluchowski equation, gas-surface reactions, diffusion,
thermophoresis, electrophoresis, conservation
equations and useful solutions. Part 2: Introduction to soot
formation, nanoparticles in reacting flows, particle transport and kinetics
in flames, atmospheric heterogeneous reactions, and nanocatalysis. |
