Amagesi amahlei-kryptokanyei-xenonzingakwesokudla kakhulu kwethebula le-periodic futhi zinezisetshenziswa ezingokoqobo nezibalulekile. Isibonelo, zombili zisetshenziselwa ukukhanyisa.I-Xenoniyona ewusizo kakhulu kulezi ezimbili, inezinhlelo zokusebenza eziningi kwezokwelapha kanye nobuchwepheshe benyukliya.
Ngokungafani negesi yemvelo, etholakala ngobuningi ngaphansi komhlaba,i-kryptonfuthii-xenonzakha ingxenye encane nje yomkhathi womhlaba. Ukuze ziqoqwe, amagesi kumele adlule emijikelezweni eminingana yenqubo edinga amandla amaningi ebizwa ngokuthi i-cryogenic distillation, lapho umoya ubanjwa khona bese upholiswa ufike kuma-degrees Fahrenheit angaba ngu-300. Lokhu kupholisa okukhulu kuhlukanisa amagesi ngokwezinga lawo lokubila.
Okushai-kryptonfuthii-xenonubuchwepheshe bokuqoqa obusindisa amandla nemali bufiseleka kakhulu. Abacwaningi manje bakholelwa ukuthi bathole inqubo enjalo, futhi indlela yabo ichazwe kabanzi kuyi-Journal of the American Chemical Society.
Ithimba lenze i-silicoaluminophosphate (SAPO), ikristalu equkethe ama-pores amancane kakhulu. Ngezinye izikhathi ubukhulu be-pore buphakathi kobukhulu be-athomu ye-krypton kanye ne-athomu ye-krypton.i-xenoni-athomu. Encanei-kryptonama-athomu angadlula kalula ezimbotsheni kuyilapho ama-athomu amakhulu e-xenon ebhajwa. Ngakho-ke, i-SAPO isebenza njengesihlungi sama-molecule. (Bheka isithombe.)
Besebenzisa ithuluzi labo elisha, ababhali babonise ukuthii-kryptonisakazeka ngokushesha izikhathi ezingu-45 kunei-xenon, okubonisa ukusebenza kwayo kahle ekuhlukaniseni igesi enhle ekamelweni lokushisa. Ukuhlolwa okwengeziwe kubonise ukuthi i-xenon ayigcinanga nje ngokulwa nokucindezela kulezi zimbobo ezincane, kodwa futhi yayivame ukunamathela kumakristalu e-SAPO.
Engxoxweni ne-ACSH, ababhali bathi ukuhlaziywa kwabo kwangaphambilini kubonise ukuthi indlela yabo inganciphisa amandla adingekayo ukuze kuqoqwei-kryptonkanye ne-xenon cishe ngamaphesenti angu-30. Uma lokhu kuyiqiniso, khona-ke ososayensi bezimboni kanye nabathandi bokukhanya okukhanyayo bazoba nokuningi abazoziqhenya ngakho.
