Crystals can be grown from a vapour when the molecules of the gas attach themselves to a surface and move into the crystal arrangement.
Red Bull use their rear bodywork to keep the exhaust gases attached all the way to the area they want them.
When they exposed human skin to saturated mustard gas for 10 seconds, the scientists found that sulfur in the gas attaches itself to keratin, forming a new, detectable chemical bond in the skin.
The trolley does not have gas cylinders attached but has hoses which plug into the wall gas supply.
They look like invalids on drips, like gas masks attached to collapsing bodies, or disease-engorged organs.
Schedin et al. reported that micrometer-size sensors made from graphene were capable of detecting single gas molecules attached to or detached from graphene's surface, as depicted in Fig. 3 [24].
The Europeans and a large majority of smaller nations are adamant that any future accord be legally binding, while China, India, the United States and several other major emitters of greenhouse gases have attached some difficult conditions to participation in any mandatory agreement.
The dining hall had tear-gas canisters attached to the rafters of the ceiling which could be activated by remote control, should prisoners riot or attempt to escape.
At constant temperature and equilibrium conditions, the average number of molecules in the gas and solid states is constant; molecules leave the gas and attach to the surface at the same rate that they leave the surface to become gas molecules.
The gas entered the solution via a 60 um pore gas diffuser (Fisher Scientific) attached to the end of the gas supply line downstream of the control valve.
