Electron-dancing in the fire salamander

London chemists at the University College have discovered new qualities conventional flame that occur during combustion. They discovered new details of the interaction of the solid surface with a flame.

Scientists have created a new method for controlling redox processes on solid surfaces, which has great potential in the detection of chemicals in the atmosphere or lightning research, as well as removal of greenhouse gases from the air.

Presence on the surface of a solid body of certain chemicals in the combustion process determines the course of the release of a number of electrons, which gives the opportunity to obtain specific performance of electric voltage. The data presented allow for microscopic traces accurately determine the composition of the components of combustion. Voltage monitoring provides the ability to control the oxidation-reduction reactions in the solid state.

Chemists have created a highly accurate electrodes that can probe the chemical composition of the fire and get the chart it voltammetry. Such voltammograms considered unique for three different metal oxides (vanadium oxide, molybdenum oxide, tungsten oxide) and largely independent of the number of nitrogen in the flame.
