This week's research published in Science Advances shows that it may be used to make rocket fuel that is much cleaner and safer than the hypergolic fuel that are commonly used today. And still just as effective. The new fuels use simple chemical "triggers" to unlock the energy of one of the hottest new materials, a class of porous solids known as metal-organic frameworks, or MOFs. MOFs are made of clusters of metal ions and an organic molecule called a left.
hypergols, which are so energetically ignored in the presence of oxidizers (since there is no oxygen to support the Earth's atmosphere) , The hypergolic fuels that are currently primarily in use depend on hydrazine, a highly toxic and dangerously unstable chemical compound made up of a combination of nitrogen and hydrogen atoms. Hydrazine-based fuels are so carcinogenic that those who work with them need to be prepared. Despite this, around 1
"This is a new, cleaner approach to making highly combustible fuels "It's an essential quality in rocket fuel," says Tomislav Friščić. McGill researcher Robin D. Rogers.
"Although we are still in the early stages of working with these materials in the lab, these results open up the possibility of developing a class of new, clean and highly tunable hypergolic fuels for the aerospace industry," says the first author, Hatem Titi, a post-doctoral fellow who works in Friščić's lab.
Friscis is interested in commercializing this technology, and wants to work with McGill and Acsynam, an existing spin-off company from his laboratory, to make this happen.
