Neem oil (Azadirachta indica) as a promising feedstock for biolubricant production: enzymatic synthesis, process optimization, and molecular studies

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 237-252, January/February 2026.
Abstract The fuel industry remains closely tied to oil‐based fuels. This relationship is responsible for increasing greenhouse gas emissions. Biofuels are an alternative to petroleum‐based fuels that could make industrial production lines more sustainable.

Extraction, Process Optimization, and Characterization of Aloe weloensis Oil (AWO) Using Box–Behnken Design (BBD) and FTIR Analysis

Journal of Engineering, Volume 2026, Issue 1, 2026.
Renewable energy is a cornerstone in the harnessing of eco‐friendly systems that offer economical and efficient alternatives to nonrenewable energy. Today, alternative forms of energy are being implemented to lower the emissions of pollutants from different petroleum engines. The specific aims of this study are to develop the highest Aloe weloensis oil

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 ...
