outgas

However it is very difficult to remove, and tends to outgas in an unexposed state.

In the second case, frothing may be produced as both the sample and the resin outgas together.

The higher the temperature, the less residence time in the vacuum environment is required to outgas the same quantity of material.

Then we allow the volatiles to outgas through a diatreme vent.

Even materials which are not generally considered absorbent can outgas, including most plastics and some metals.

If methane is captured rather than allowed to outgas, it can be used for fuel, closing the carbon cycle.

Normal copper is unsuitable for high vacuum as it is difficult to outgas completely.

Another incorrect theory was that the heat on the dark side was causing the material to outgas, which pushed the radiometer around.

This residual gas may be dissolved or in sub-clinical bubble form, and will continue to outgas while the diver remains at the surface.

So above 550 C, calcium carbonate begins to outgas CO into air.

There might be a few bits of soft stuff that could still outgas and need retrajectoring, but they all have their own escort engines anyway.'

Dive tables make provisions for post-dive time at surface level before flying to allow any residual excess nitrogen to outgas.

But since centaurs are icy comet-like bodies that may outgas, it is very difficult to estimate their albedos.

"The residues outgas and waft away."

All this implies greater volcanicity because the Earth was attempting to outgas radioactive heat at the spreading ridges, and so massive 'hot spots' appeared.

Some types of RTV sealants outgas the poison cyanide for weeks after application.

These fumes may also come from phthalates and other plastic-softening chemicals (plasticizers) that evaporate (or outgas) over time.

Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas.

Materials outgas by two mechanisms: release of adsorbed and absorbed gases, and evaporation of the material itself.

As torbernite is radioactive and outgas radon (Rn), collectors are urged to take proper precautions in the handling and storage of any specimens.

Carbon dioxide and hydrogen may form from organic materials, moisture is outgassed by polymers and amine-cured epoxies outgas ammonia.

(color vs. temperature)' If brake materials outgassed at drum temperatures, they would also outgas at disc temperatures and would fade substantially.

The lighter elements outgas in a relatively short period of time, so the elements necessary for water and air are absent, even if there were a source of heat."

When such oxygen sinks became saturated, free oxygen began to outgas from the oceans 2.7 billion years ago, reaching 10% of its present level around 1.7 billion years ago.
