Automatic parameter update algorithm for regression models to estimate remaining useful life: Application in an offshore natural gas dehydration unit

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Remaining useful life (RUL) analysis of equipment prevents failures and assists in maintenance to address impending failures. To achieve this, the advancement of degradation can be measured through a determinant variable. This work presents a new methodology for estimating the number of remaining cycles (NRC), or RUL, of equipment in cyclic ...

Energy Landscapes in Chemical Reactions and Transport

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Recent Advances in Catalytic Conversion of Bioethanol to 1,3‐Butadiene: Reaction Mechanism, Catalyst Design, and Process Scalability

open access: yesChemSusChem, EarlyView.
Catalytic conversion of ethanol to 1,3‐butadiene (BD) can proceed via one‐step and two‐step routes. In the one‐step process, pure and metal‐modified MgO–SiO2 catalysts enable direct ethanol transformation to BD, while ZrO2‐based catalysts drive the two‐step pathway.
