Microscopic image of the biodiesel emulsion fuel created by researchers
Nanoparticles have added yet another string to their microscopic bows with a new study showing that the addition of alumina nanoparticles can improve the performance and combustion of biodiesel, while producing fewer emissions. In the study, a team at India’s National Institute of Technology in Tiruchirappalli used nanoparticles with an average diameter of 51 billionths of a meter. The high surface-to-volume ratio of the nanoparticles means they have more reactive surfaces, which allows them to act as more efficient chemical catalysts and results in increased fuel combustion.
