Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:

Discovery of PHB... Polyhydroxybutyrate‚ or PHB‚ was discovered in 1926 by French microbiologist‚ Maurice Lemoigne‚ who was researching the use of bacteria to produce polyesters‚ at the time. However‚ it was overlooked and forgotten for over 30 years‚ as there wasn’t any need for such a biopolymer; petroleum was still inexpensive and abundant so PHB was unnecessary. In 1957‚ PHB was rediscovered in Britain and USA‚ and was further developed and researched during the 1960s. The mass production

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are
