Lectures-5 to 7:
Fundamental Equations for Reactor Engineering
The basis of most of reactor modeling is a set of fundamental balance equations. These
equations are mathematical statements of physical laws that require conservation of mass,
energy, momentu
Lectures 12-17: Reactions at Solid Surfaces and Transport
Effects in Heterogeneous Reactions
For the next couple of lectures, we will consider reactions at surfaces. We will primarily look at
heterogeneous catalysis at gas-solid interfaces, where the soli

Linear Stability Analysis of Steady States:
As discussed qualitatively, we expect that for the cases where there are three steady state
solutions, the upper and lower steady states are stable, while the middle steady state

Chromatography (from Greek word for chromos for color) is
the collective term for a family of laboratory techniques for the
separation of mixtures.

SEM uses electrons instead of light to
form an image
Since their development in the early
1950's, scanning electron microscopes
have developed new areas of study in the
