The PSRs are so frigid that regolith becomes an extremely poor conductor of electricity.
conductor — a material through which energy can be easily transferred as heat Gases are poor conductors because particles too far apart Liquids are decent conductors, but solids are the best because particles collisions occur more easily.
And second, air is too poor a conductor.
All these applications come out of the specific properties of quasicrystals, that they are poor conductors of heat, they have very low - energy surfaces, they have low friction and they have low adhesion properties.
Cast iron is a poor conductor of heat.
Bismuth vanadate absorbs light but is a poor conductor of electricity.
Less than two years ago, Kanatzidis and his team, with postdoctoral fellow Lidong Zhao as protagonist, identified tin selenide as a surprisingly good thermoelectric material; it is a poor conductor of heat (much like wood)-- a desirable property for a thermoelectric — while maintaining good electrical conductivity.
And, although the same effect could be had by adding the rusted red iron mineral hematite, which is a poor conductor, the resulting microbial growth was much smaller and slower (and nonexistent when nonconductive aluminum minerals were tried).
However, ice is a poor conductor so, unless ice is very thin or the geothermal heat flux very high, tends not to influence melt at the ice surface.
This is because stainless steel stands up to high temperatures but is a poor conductor of heat, while aluminum is a great conductor but can't handle the heat.
Zircotec's coating is a 0.3 mm thick layer made up of zirconia ceramics, and works by creating small pockets of air within the thin layer and, because air is a poor conductor, it stops much of the heat getting through.
anticlimactic; In fact nowadays coffee flasks rarely have a silvered lining as the glass is replaced by stainless steel which is a poor conductor — another indication of how little radiation matters at these temperatures.
Since air is quite a poor conductor, conduction is not a particularly important energy transmission mechanism for the atmosphere.
