Knock, Knock: Who’s There? [PDF]
Circulation, 2013 It has become apparent that major sources of reactive oxygen species (ROS) in mammalian cells are the NADPH oxidases. These multimeric enzymes are composed of membrane-bound catalytic subunits, or Nox enzymes, and a small docking subunit called p22phox.

Improving Fuel Economy and Engine Performance through Gasoline Fuel Octane Rating
Energies, 2020 The octane number is a measure of the resistance of gasoline fuels to auto-ignition. Therefore, high octane numbers reduce the engine knocking risk, leading to higher compression threshold and, consequently, higher engine efficiencies. This allows higher
