Allows for Safe and Remote Ignition of Explosives, Fuels, and Propellants
These functionalized fullerenes can be ignited with low-intensity lasers, allowing uniform coating on explosives for homogeneous or multi-point ignition. Many industrial processes require ignition to start chemical conversions, and electric spark and laser are the most popular. Electric spark ignition requires input from high-voltage sources, which can be affected by stray electromagnetic fields or electrostatic discharge or stray electrical energy. Laser based ignition requires high-energy input in the orders of GW/cm2. Researchers at the University of Florida have discovered that functionalized fullerenes can be ignited with low-intensity (kW/cm2) laser. The solvent compatibility of functionalized fullerenes allows uniform coating on explosives for homogeneous or multi-point ignition. Functionalized fullerenes as additives to fuels can lower the energy required for laser spark plugs and facilitate homogenous and complete combustion. Use of functionalized fullerenes that are water-soluble, biocompatible and biodegradable, eliminates toxicity and other environmental concerns.
