Corrigendum to “Viscosities of some fatty acid esters and biodiesel fuels from a rough hard-sphere-chain model and artificial neural network” [Fuel 235 (2019) 1083–1091] (Fuel (2019) 235 (1083–1091), (S0016236118314571), (10.1016/j.fuel.2018.08.088))

After a careful reconsideration of the article (S. M. Hosseini, M. Pierantozzi, J. Moghadasi, Fuel 235 (2019) 1083–1091), several typo have appeared in the key equations of this article which would not allow the readers to utilize the underlying molecular semi-theoretical model for the calculation of dynamic viscosity of pure fatty acid esters and biodiesels without any problem. Regarding this, an Erratum is presented to fix this issue.
