An Experimental–Numerical Study on Oxidation Inhibition of SiO₂ Nanoparticles in Biolubricants for Internal Combustion Engines

Applied Sciences
Modern agriculture depends heavily on machinery to maximize operational efficiency and, consequently, profitability, but the wear-and-tear on the mechanical components of machinery due to ageing can lead to reduced efficiency, more downtime, and higher ...

A Semi-Mechanistic Approach to Modeling Lipase-Catalyzed Processes with Multiple Competing Reactions: Demonstration for the Esterification of Trimethylolpropane

Biomass
Kinetic models are important tools for guiding the design and optimization of lipase-catalyzed processes. These processes follow the Ping Pong bi bi mechanism, for which mechanistic kinetic equations can be derived.
