(1) Instead, new engines have been designed to run on lower octane gasoline, which is made of hydrocarbons that are resistant to knock.(2) Four different solvent media were considered: octane , tetrahydrofuran, acetonitrile, and water.(3) My job was to change the plastic numbers displaying the price of 87 - octane standard unleaded gasoline from $1.54 to $1.56.(4) Carbon in its most reduced form is found in alkanes, which are typically fuels like methane, propane, and octane .(5) To test the validity of the open-state model, molecular dynamics simulations in octane , a lipid bilayer mimetic, were carried out.
