Renewable energy sources are gaining increasing importance in the global pursuit of sustainable development. Among these, biodiesel stands out as a promising alternative to conventional fossil fuels. Biodiesel is typically produced from vegetable oils through a process known as transesterification, which yields fatty acid methyl esters (FAME). Thes

Nanoparticles possess unique optical properties that have sparked considerable interest in their application for diverse technological sectors. Upconversion nanoparticles (UCNPs), a particular class of nanomaterials, exhibit the remarkable ability to convert near-infrared light into visible light. This phenomenon has unlocked vast possibilities in
