U. team injected him with antibiotics and sedatives, put a breathing tube down his throat, and forced pure oxygen into his lungs.
The chamber is pressurized with pure oxygen, and the pressure inside the chamber will slowly rise to about two and a half times normal atmospheric pressure.
At one point her lungs "required 100% pure oxygen to be fed to her through a respirator, " as the bacteria ravaged her body, her father wrote.
Meanwhile, other completely different approaches involve burning coal in pure oxygen (oxyfuel), or turning it into a mixture of carbon monoxide and hydrogen, which is then burned.
Two other techniques, called gasification and oxy-combustion, work by reacting coal with pure oxygen rather than air, and thus produce exhausts that require little treatment before burial.
To keep turbine sales spinning, Immelt has turned to a process that partially burns pulverized coal in the presence of pure oxygen to turn it into a flammable gas that can drive linked gas and steam turbines.
Household waste, for example, would be reduced to pure carbon, oxygen and hydrogen, along with a handful of heavier elements (tungsten, iron, aluminium and so on) which could then be re-used.
In this case the fatty acids would have 18-30 carbon atoms, and the final stage of the synthetic pathway would clip off the oxygen atoms to create pure hydrocarbons.
One plus is that, apart from the possibly dirty business of generating it, the gas is the cleanest fuel on the planet, combining with oxygen to create H2O, pure water vapor.
They fill the container with pure air made by evaporating liquid nitrogen and liquid oxygen, and add water vapour and some trace gases.
The next trick, which Exxon's money will help pay for, is to tweak the biochemical pathway that makes the algal oil (which is known, technically, as a triglyceride, and has oxygen atoms in it as well as carbon and hydrogen) so that the oxygen-containing parts of the molecules are snipped off and a pure hydrocarbon is left.
