Book excerpt: Nanotechnology for Advanced Biofuels: Fundamentals and Applications highlights emerging techniques for the formulation of fuels using nanotechnology and bio-based concepts. The addition of high-energy nanoparticles and biologically derived molecules in liquid fuel can increase the potential of energy-rich compounds. Key challenges in the production of nanotechnology-based fuels and their combustion or ignition during the operation are covered, along with the emission of oxidized particles and by-products of incomplete combustion and nano-fuels as an emerging field. The bio-based energy-rich fuels are largely diffused in conventionally used fuels. The addition of biofuels and nano-additives to pre-existing fuels can offer opportunities for developing modified fuels in domestic industries with the maximum usage of renewable biomass. This is an important reference source for materials scientists, energy scientists and chemical engineers who want to understand more about how nanotechnology can help create more efficient biofuels. - Shows how nano-additives can significantly improve the properties and efficiency of biofuels - Provides information to help readers better understand the basic and advanced applications of nano-additive-based biofuels - Assesses the challenges of manufacturing nanotechnology-enhanced biofuels on an industrial scale
