Njira yatsopano yosagwiritsa ntchito mphamvu zambiri yochotsera mpweya wopanda mphamvu mumlengalenga

Mpweya wabwino kwambirikripton ndixenonali kumanja kwenikweni kwa tebulo la periodic ndipo ali ndi ntchito zothandiza komanso zofunika. Mwachitsanzo, onse awiri amagwiritsidwa ntchito powunikira.XenonNdi yothandiza kwambiri kuposa ziwirizi, yokhala ndi ntchito zambiri mu zamankhwala ndi ukadaulo wa nyukiliya.
Mosiyana ndi gasi wachilengedwe, womwe umapezeka pansi pa nthaka,kryptonndixenonZimapanga gawo laling'ono chabe la mlengalenga wa dziko lapansi. Kuti zisonkhanitsidwe, mpweyawu uyenera kudutsa mu njira zingapo zogwiritsa ntchito mphamvu zambiri zotchedwa cryogenic distillation, momwe mpweya umatengedwa ndikuzizidwa mpaka madigiri -300 Fahrenheit. Kuzizira kwambiri kumeneku kumalekanitsa mpweyawu malinga ndi kutentha kwawo.
ChatsopanokryptonndixenonUkadaulo wosonkhanitsira zinthu womwe umasunga mphamvu ndi ndalama ndi wofunika kwambiri. Ofufuza tsopano akukhulupirira kuti apeza njira yotereyi, ndipo njira yawo yafotokozedwa mwatsatanetsatane mu Journal of the American Chemical Society.
Gululi linapanga silicoaluminophosphate (SAPO), kristalo yokhala ndi ma pores ang'onoang'ono kwambiri. Nthawi zina kukula kwa ma pores kumakhala pakati pa kukula kwa atomu ya krypton ndixenonatomu. Yaing'onokryptonmaatomu amatha kudutsa mosavuta m'mabowo pomwe maatomu akuluakulu a xenon amamatira. Motero, SAPO imagwira ntchito ngati sieve ya molecular. (Onani chithunzi.)
Pogwiritsa ntchito chida chawo chatsopano, olembawo adawonetsa kutikryptonimafalikira mofulumira nthawi 45 kuposaxenon, kusonyeza kuti imagwira ntchito bwino pogawa mpweya wabwino kutentha kwa chipinda. Kuyesa kwina kunasonyeza kuti xenon sikuti inkangovutika kulowa m'mabowo ang'onoang'ono awa, komanso inkakonda kumamatira ku makhiristo a SAPO.
Mu kuyankhulana ndi ACSH, olembawo adati kusanthula kwawo kwakale kunawonetsa kuti njira yawo ingachepetse mphamvu zomwe zimafunika kuti zisonkhanitsidwekryptonndipo xenon ndi pafupifupi 30 peresenti. Ngati izi ndi zoona, ndiye kuti asayansi a mafakitale ndi okonda kuwala kwa fluorescent adzakhala ndi zambiri zoti anyadire nazo.

Dr. Alex Berezov ndi katswiri wa sayansi ya tizilombo toyambitsa matenda, wolemba sayansi komanso wokamba nkhani amene ali katswiri wotsutsa sayansi yabodza ya American Council on Science and Health. Iye ndi membala wa bungwe la olemba la USA TODAY komanso wokamba nkhani ku The Insight Bureau. Poyamba, anali mkonzi woyambitsa wa RealClearScience.
Bungwe la American Council on Science and Health ndi bungwe lofufuza ndi kuphunzitsa lomwe limagwira ntchito motsatira gawo 501(c)(3) la Internal Revenue Code. Zopereka sizilipira msonkho konse. ACSH ilibe zopereka. Timasonkhanitsa ndalama makamaka kuchokera kwa anthu ndi mabungwe chaka chilichonse.
