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

Scanning Electron Microscope
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
medical and physical science communities

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