Methanol (CH3OH) is thought to form on interstellar ice dust via successive hydrogenation reactions. The reaction between CH3 and OH radicals could also conceivably generate methanol at temperatures above approximately 20 K, at which…
Silicon, despite its abundance and high energy density, remains underexplored as a carbon-free fuel, with limited data available on its combustion characteristics. In this work, the combustion behaviour of silicon particles is examined…
Biofuels have shown to be a reliable source of energy and a replication of fossil fuels. A well-known branch of biofuels is oxygenated ones derived from lignin compounds. Although a wide range of studies was done on oxygenated fuels,…
