B30 biodiesel represents a important step towards decreasing reliance on petroleum-based diesel and promoting a more sustainable energy future. This blend consists of up to 30% renewable diesel, obtained from various sources like rapeseed and other plant oils, blended with 70% regular diesel. The use of B30 offers a range of upsides, including mini

PbSe quantum particle 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 near-infrared spectrum. By meticulously tuning the size and composition of the PbSe
