Introduction
... Metalized capacitors have a self-healing behavior as an intrinsic characteristic. Self healing is the ability to recover after a dielectric breakdown. Due to their construction, very thick electrodes, film/foil capacitors can carry higher currents than metalized types, but are much larger in volume. ...

A 1H-NMR thermometer suitable for cryoprobes
... In many NMR measurements one has to know the sample temperature exactly, e.g. during dynamic NMR investigations. Therefore it is convenient to have an NMR sample that has a known temperature-dependent chemical shift, or shift difference, so that the temperature can be determined (‘NMR thermometer’). ...

Thermal runaway
Thermal runaway refers to a situation where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result. It is a kind of uncontrolled positive feedback.In other words, ""thermal runaway"" describes a process which is accelerated by increased temperature, in turn releasing energy that further increases temperature. In chemistry (and chemical engineering), this risk is associated with strongly exothermic reactions that are accelerated by temperature rise. In electrical engineering, thermal runaway is typically associated with increased current flow and power dissipation, although exothermic chemical reactions can be of concern here too. Thermal runaway can occur in civil engineering, notably when the heat released by large amounts of curing concrete is not controlled. In astrophysics, runaway nuclear fusion reactions in stars can lead to nova and several types of supernova explosions, and also occur as a less dramatic event in the normal evolution of solar mass stars, the ""helium flash"".There are also concerns regarding global warming that a global average increase of 3-4 degrees Celsius above the preindustrial baseline could lead to a further unchecked increase in surface temperatures. For example, releases of methane, a greenhouse gas more potent than CO2, from wetlands, melting permafrost and continental margin seabed clathrate deposits could be subject to positive feedback.
