After pinpointing the contaminated trash, they began to search the surrounding material for clues.
Because the gas is tightly contained in the borehole, its expansion splits the surrounding material.
The pressure strongly increases in the newly ionized zone, so the ionized gas flows out through the surrounding material.
As a side effect of annealing, the implanted atoms usually move a little, diffusing into the surrounding material.
The wires were also of exactly the right length and separation to smoulder and ignite the surrounding material rather than just breaking when the power shorted.
The chemical lab, like its germ counterpart, has a small steel air-lock door through which samples are passed and the surrounding material decontaminated.
However, the R.I. of the cell structure varies slightly from the surrounding material, and it is possible to exploit this difference.
In laser glazing, a brief intense laser pulse melts a tiny spot, which is swiftly quenched by the surrounding material into a glass.
Energetic jets blasting from the galaxy's central black hole are heating up surrounding material and making it glow but they also power shock waves that are driving gases out of the galaxy's interior.
The work has not gone perfectly -- the cornices and window hoods were more harshly cleaned and now look as if they are floodlit, compared to the more gently cleaned surrounding material.
Clusters grow by gravity, according to cosmological theory, starting as small dimples in the heat and fizz of the Big Bang and then drawing in surrounding material over the eons.
