Chemical reactions involving thermal runaway are also called thermal explosions in chemical engineering, or runaway reactions in organic chemistry.It is a process by which an exothermic reaction goes out of control: the reaction rate increases due to an increase in temperature, causing a further increase in temperature and hence a further rapid increase in the reaction rate.

Clustered distribution of current density over the junction or current filaments lead to current crowding localised hot spots, which may evolve to a thermal runaway. Reverse bias. Some semiconductor devices are diode junction-based and are nominally rectifiers; however, the reverse-breakdown mode may be at a very low voltage, with a moderate ...
A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor , either collapses to a neutron star or black hole , or is completely destroyed to form a diffuse nebula .
Convicted killer was tracked down using thermal imaging technology before tactical teams surrounded him and – with the help of a police dog – captured him at around 8am on Wednesday morning
Runaway reaction, a chemical reaction releasing more heat than what can be removed and becoming uncontrollable; Thermal runaway, self-increase of the reaction rate of an exothermic process while temperature increases with the heat released and giving rise to an explosion
