Not exact matches

Oxygen atoms ringing the pore bonded to one water molecule, which then entered the spherical cage under high temperature and pressure (Science, DOI: 10.1126 / science.1206376).

The treatments, administered at the Institute of Hyperbaric Medicine at Assaf Harofeh Medical Center, headed by Dr. Efrati, consisted of 40 one - hour sessions, administered five times a week over two months, in a high pressure chamber, breathing 100 % oxygen and experiencing a pressure of 1.5 atmospheres, the pressure experienced when diving under water to a depth of 5 meters.

«Interactions between oxygen and iron dictate Earth's formation, differentiation — or the separation of the core and mantle — and the evolution of our atmosphere, so naturally we were curious to probe how such reactions would change under the high - pressure conditions of the deep Earth,» said Mao.

Under similar pressures but higher temperatures, it has been suggested that ice X could possibly transform into a phase of ice that can conduct electricity as hydrogen atoms move freely around the oxygen lattice.

It turns out that water contained in some minerals that get pulled down into Earth due to plate tectonic activity could, under extreme pressures and temperatures, split up — liberating hydrogen and enabling the residual oxygen to combine with iron metal from the core to create a novel high - pressure mineral, iron peroxide.

With the combination of in situ synchrotron infrared spectroscopic measurements carried out at high pressure, and ab initio calculations on the ferromagnesite structure, it was possible to identify a unique vibrational signature present only in the high - pressure phase, and thus a new carbon - oxygen bond forms in ferromagnesite under pressure.

(b) The ability to grow high quality film and bulk samples by a variety of growth techniques including sputtering, pulse laser deposition (PLD), evaporation, bulk ceramic processing, hydrothermal growth and HIP and Hot Pressing processing can be done under an extremely broad range of temperature and oxygen partial pressure as suggested by theory and experiment.

Other accomplishments of the 17 member team included the discovery an offshoot cave on the south wall of the Blue Hole, encouraging results of Doppler testing on mixed gas divers, a study confirming pseudomonas bacteria growth under high oxygen partial pressure study, a survey of the giant speleothem gallery on the south wall and successful dives by six additional Cambrian Foundation members to the bottom of the Blue Hole.
