(Feb.5, '15) Sandia National Laboratories researchers are the first to
directly measure hydroperoxyalkyl radicals — a class of reactive molecules
denoted as “QOOH” — that are key in the chain of reactions that controls the
early stages of combustion. This breakthrough has generated data on QOOH
reaction rates and outcomes that will improve the fidelity of models used by
engine manufacturers to create cleaner and more efficient cars and trucks.
