In propellant systems, fuels of choice continue to be hydrazine and its derivatives, even
though they comprise a class of acutely carcinogenic and toxic substances which exhibit …

A virtually unprecedented exponential burst of activity resulted following the publication, in
1998, of an article by Michael Freeman (Freemantle, M. Chemical & Engineering News …

In the present mini‐review, droplet impacting on a liquid pool, jet impingement, and binary
droplet collision of nonreacting liquids are first summarized in terms of basic phenomena …

Tetramethylethylenediamine (TMEDA) is a promising green propellant fuel and reactivity
promoter. However, the reactions between TMEDA and O 2 are usually overlooked under …

Complexation of amines with borane converts them to hypergols or decreases their ignition
delays (IDs) multifold (with white fuming nitric acid as the oxidant). With consistently low IDs …

Hypergolic ignition by the binary collision of H 2 O 2 and Monoethanolamine (MEA)-NaBH 4
droplets has been experimentally studied with an emphasis on droplet inter-mixing, heat …

Ionic liquids are promising candidates for future fuels in space propulsion. In this work, six
ionic liquids with thiocyanate anions are proposed as new fuel candidates with hydrogen …

The hypergolic interactions between monomethylhydrazine (MMH, CH3NHNH2) and
various forms of nitric acid were studied by several different experimental techniques. High …

Hypergolic ignition by the head-on collision of a smaller N, N, N′, N′−
tetramethylethylenediamine (TMEDA) droplet and a larger white fuming nitric acid (WFNA) …

As of now, the most widely used hypergolic fuels are hydrazine derivates with nitrogen
tetroxide as the oxidizer. The toxicity and carcinogenic character of these substances make …
