Batch Heterogeneous Catalytic Selective Hydrogenation of Vegetable Oils Over Lindlar Catalyst: Kinetic Modeling Supported by Reaction Mechanisms

ChemistryOpen, Volume 14, Issue 12, December 2025.
Heterogeneous catalytic selective hydrogenation of vegetable oils was modeled by Hougen–Watson approach to obtain kinetic rate laws. Parameters were obtained by nonlinear regressions on batch experimental data, and the best mechanism to interpret those experimental data was chosen on a statistical basis (higher coefficient of determination R2) and by ...

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1948-1969, November/December 2025.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Supramolecular Lubricating Hydrogel Microspheres Reshape Damaged Matrix Regeneration

Advanced Science, Volume 12, Issue 37, October 6, 2025.
The supramolecular lubricating hydrogel microspheres can provide stable mechanophysical protection at damaged matrix through interfacial hydration lubrication: in the early and middle stages, microspheres can actively provide microscale supramolecular lubrication (µ ≈ 0.04) for damaged matrix; in the late stage, the wear debris induced by shear and ...
