Biodiesel has emerged as a viable alternative to conventional fossil fuels. Production of biodiesel involves repurposing vegetable oils or animal fats into a eco-friendly fuel source. The process typically utilizes a chemical transformation known as transesterification, where the oil is reacting with an alcohol, usually methanol, in the presence of

PbSe quantum nanocrystal solar cells represent a promising avenue for obtaining high photovoltaic efficiency. These devices leverage the unique optoelectronic properties of PbSe nanostructures, which exhibit size-tunable bandgaps and exceptional light absorption in the solar spectrum. By carefully tuning the size and composition of the PbSe dots, r
