On my commute to work today , I had the misfortune of being jam into a narrow tube underground . But it could have been worse : I could ’ve been splash into a single dimension .
That ’s what recently happen to some krypton atoms in an Ulm University chemistry research laboratory . Using transmission electron microscopy ( or TEM ) , a team pull off to compact the noble natural gas into a nanotube with a diameter 1/500,000th that of a human haircloth . In such a confined blank , the atom could not squeeze by one another and flux , and they became a one - dimensional natural gas . The team ’s research ispublishedin the journal of the American Chemical Society .
“ carbon paper carbon nanotube enable us to entrap atoms and accurately lieu and study them at the single - atom horizontal surface in existent - sentence , ” say Andrei Khlobystov , a pharmacist at the University of Nottingham and co - author of the survey , in a universityrelease . “ Because Kr has a high nuclear number , it is easier to observe in a TEM than lighter elements . This allowed us to track the position of Kr atoms as be active dots . ”

It ’s really hard to immobilise down atoms . They are little , and in a gaseous state they flit about at close to the speed of sound . To image the Kr , the research worker had to trap the atoms and shuttle them into a very , very small-scale exam tube .
To do this , they trapped the krypton in buckyballs — short forbuckminsterfullerene , a soccer orb - shaped corpuscle pen of 60 atomic number 6 atoms . The buckminsterfullerene dissemble as a John Milton Cage Jr. for each krypton atom . The researchers could then release the Kr from the buckyball by heating it to 2,192 degrees Fahrenheit ( 1,200 Celsius ) or irradiating it with an negatron shaft . Both methods cause the buckyballs to mix , leave behind the krypton atoms in a neat line in a carbon carbon nanotube . Once in that line , definition between each atom disappeared : they were a uniform , one - dimensional gas .
“ As far as we hump , this is the first clip that chains of noble flatulency molecule have been image right away , leading to the instauration of a one - dimensional gas pedal in a solid material , ” said Paul Brown , theater director of the University of Nottingham ’s Nanoscale and Microscale Research Centre , in the acquittance .

If we ’re being super proficient , sure , the krypton in the tube is three - dimensional in that the gas still has some volume , even if its diameter is highly narrow . It exists in the same way that‘one - dimensional ’ fibril of electronsstretch across the Milky Way coltsfoot . Still , it ’s cool . study how atoms interact can assist scientists learn how matter behaves in such cramp conditions and thus better understand nature at its extreme .
