processes, respectively. The first term follows from the progressivenucleationmechanism (PNM) advanced originally to describe overall crystallization kinetics. Equation 2 predicts a maximum value of α ( t ) at a particular value of t /Θ, but the values
new equation, based on progressivenucleationmechanism (PNM) of a solid phase during its crystallization in a closed liquid system of fixed volume.
Using the new equation, the author analyzed the growth of the number of citations per year
