Modern Progress In Inert Gasxenon Chemistry

Home | Reference-and-Education | Science

Noble Gas xenon is present in atmospheric air, but unfortunately in a very low concentrations. It is possible to say that average room have few cubic centimetres of this gas. This gas was discovered by studying of evaporation of liquid gases carried by William Ramsay. After evaporation of liquid atmospheric gas, which contains helium, hydrogen, neon, oxygen, nitrogen and argon a very small amount of liquid remaining was left in cry vessel. This liquid was krypton gas, but after evaporation a very tiny amount of other gas was left. This gas was identified as xenon. This gas emitted very unusual white light with full spectrum, from orange to violet. This light emittance activated by electrical discharge can be explained by very big electron cloud of xenon, which contains 54 electrons.

Very wide spectrum of xenon gas emittance, from infra-red to ultraviolet, activated by electrical discharge in demand in many industrial applications. Xenon gas is used for manufacturing of high pressure lamps. The high pressure light bulbs are used for production of extremely intensive full spectrum light, from infra-red to ultraviolet. This light is used in orthochromatic fabric and paint industry.

Another interesting application of xenon gas was discovered recently. Xenon molecules have hydrophobic properties and easily can bind with hydrophobic parts of protein molecules. According last researches this binding can take place only at pressures of more than 70 psi. Xenon atom is very electron rich and therefore these atoms can significantly change x-ray diffraction pattern of protein crystals without significant changes of its molecular structure, which can be used for MAD structure solution 57 protein structures were solved with xenon atoms. Coordinates for all these structures are submitted into protein data bank and everybody can look through these beautiful results. For convenience we prepare all pictures (normal and stereo view) of all xenon binding centres available in PDB data bank now.

Xenon atoms significantly interact with x-ray. As an inert gas, xenon is absolutely harmless for human body and therefore this gas can be used in x-ray diagnostic medicine.

Recent studies shows that in high concentrations xenon can act as anaestheticby inhibiting of membrane calcium pumps. Last few decades xenon became potential candidate for surgery as an anaesthetic agent due to significant reduction of production price with consequent anaesthetic price of about 2000 USD per hour of deep anaesthesia.
