Lightning, one of the major sources of nitrogen oxides (NOx) in the atmosphere, contributes to the tropospheric concentration of ozone and to the oxidizing capacity of the atmosphere. Lightning produces between 2 and 8 Tg N yr−1 globally and on ave

The protective aluminum oxide film naturally formed on a surface of aluminum has a thickness in the range of 3–5 nm. Its melting causes loss of its continuity, which may significantly affect the ignition and combustion processes and their relative
