Editing Logistic function (section)

=== In chemistry: reaction models ===
The concentration of reactants and products in [[autocatalysis|autocatalytic reactions]] follow the logistic function.
The degradation of [[Platinum group]] metal-free (PGM-free) oxygen reduction reaction (ORR) catalyst in fuel cell cathodes follows the logistic decay function,<ref>{{cite journal |last1=Yin |first1=Xi |last2=Zelenay |first2=Piotr |title=Kinetic Models for the Degradation Mechanisms of PGM-Free ORR Catalysts |journal=ECS Transactions |date=13 July 2018 |volume=85 |issue=13 |pages=1239–1250 |doi=10.1149/08513.1239ecst|osti=1471365 |s2cid=103125742 |url=https://www.osti.gov/biblio/1471365 }}</ref> suggesting an autocatalytic degradation mechanism.
