Iigesi ezintleikripton kunyexenonzisekunene kakhulu kwiperiodic table kwaye zinosetyenziso olusebenzayo nolubalulekileyo.Ngokomzekelo, zombini zisetyenziselwa ukukhanyisa.Xenonyeyona nto iluncedo kwezi zimbini, ukuba nezicelo ezininzi kwezamayeza nakwiteknoloji yenyukliya.
Ngokungafaniyo negesi yendalo, eninzi phantsi komhlaba,ikriptonikwayexenonbenza iqhezu elincinane lomoya ojikeleze umhlaba.Ukuziqokelela, iigesi kufuneka zidlule kwimijikelo eliqela yenkqubo ethatha amandla ngamandla ebizwa ngokuba yi-cryogenic distillation, apho kubanjwa umoya uze upholiswe ukuya kutsho kuma-300 degrees Fahrenheit.Oku kupholisa okugqithisileyo kwahlula iigesi ngokwendawo yazo yokubila.
Entshaikriptonikwayexenonitekhnoloji yokuqokelela egcina amandla kunye nemali inqweneleka kakhulu.Abaphandi ngoku bakholelwa ukuba bafumene ubuchule obunjalo, kwaye indlela yabo ichazwe kwiJenali yeAmerican Chemical Society.
Iqela lenze i-silicoaluminophosphate (SAPO), ikristale equlethe iipores ezincinci kakhulu.Ngamanye amaxesha ubukhulu bepore buphakathi kobukhulu beathom yekrypton kunye ne-axenonathom.Encinciikriptoniiiathom zinokudlula ngokulula kwi pores ngelixa iiathom ezinkulu zexenon zixinga.Ngaloo ndlela, i-SAPO isebenza njengesefa yemolekyuli.(Jonga umfanekiso.)
Besebenzisa isixhobo sabo esitsha, ababhali babonisa okoikriptoniisasazeke ngamaxesha angama-45 ngokukhawuleza kunexenon, ebonisa ukusebenza kakuhle kwayo ekuhlukaneni kwegesi ehloniphekileyo kwiqondo lokushisa.Imifuniselo eyongezelelweyo ibonise ukuba i-xenon ayizange izame nje ukucudisa ezi pores zincinci, kodwa ithande ukubhengeza kwiikristale ze-SAPO.
Ngodliwano-ndlebe kunye ne-ACSH, ababhali bathi uhlalutyo lwabo lwangaphambili lubonise ukuba indlela yabo inokunciphisa amandla afunekayo ukuqokelelaikriptonikunye nexenon malunga nama-30 ekhulwini.Ukuba oku kuyinyani, ngoko izazinzulu zezoshishino kunye nabathandi bokukhanya kwe-fluorescent baya kuba neqhayiya kakhulu.
