The inherent drawbacks of biodiesel, particularly its poor performance in cold climates, necessitate the use of nano-additives to improve its cold flow properties such as the cloud point (CP), pour point (PP), and cold filter plugging point (CFPP). I

Extraction of biodiesel from waste cooking oil, jatropha, and corn oils is done by transesterification. Diesel and biodiesel were blended at 20% volume ratio to make methyl ester. At doses of 25, 50, and 100 mg/l, carbon nanotubes (CNTs) was mixed wi
