Njira yatsopano yosagwiritsa ntchito mphamvu yochotsera mpweya wa inert mumpweya

Mipweya yabwinokrypton ndixenonzili kumanja kwa periodic table ndipo zili ndi ntchito zothandiza komanso zofunika. Mwachitsanzo, onsewa amagwiritsidwa ntchito powunikira.Xenonndizothandiza kwambiri paziwirizi, kukhala ndi ntchito zambiri zamankhwala ndi zida zanyukiliya.
Mosiyana ndi gasi wachilengedwe, amene ali wochuluka pansi pa nthaka,kryptonindixenonzimapanga kachigawo kakang’ono chabe ka mlengalenga wa dziko lapansi. Kuti asonkhanitse, mpweyawo uyenera kudutsa njira zingapo zopangira mphamvu zambiri zomwe zimatchedwa cryogenic distillation, momwe mpweya umatengedwa ndikuzizira mpaka -300 degrees Fahrenheit. Kuzizira koopsa kumeneku kumalekanitsa mipweyayo molingana ndi kuwira kwake.
Chatsopanokryptonindixenonteknoloji yosonkhanitsa yomwe imapulumutsa mphamvu ndi ndalama ndizofunika kwambiri. Ofufuzawa tsopano akukhulupirira kuti apeza njira yotereyi, ndipo njira yawo ikufotokozedwa mwatsatanetsatane mu Journal of the American Chemical Society.
Gululo lidapanga silicoaluminophosphate (SAPO), kristalo wokhala ndi ma pores ang'onoang'ono. Nthawi zina kukula kwa pore kumakhala pakati pa kukula kwa atomu ya kryptoni ndi axenonatomu. Zing'onozing'onokryptonimaatomu amatha kudutsa pores mosavuta pomwe ma atomu akuluakulu a xenon amamatira. Choncho, SAPO imagwira ntchito ngati sieve ya molekyulu. (Onani chithunzi.)
Pogwiritsa ntchito chida chawo chatsopano, olembawo adawonetsa izikryptoniimafalikira nthawi 45 mwachangu kuposaxenon, kusonyeza mphamvu zake mu kulekanitsa gasi wolemekezeka kutentha firiji. Kuyesera kwina kunawonetsa kuti si xenon yokha yomwe idavutikira kupyola tinthu ting'onoting'ono timeneti, komanso inkakonda kukopa makhiristo a SAPO.
Poyankhulana ndi ACSH, olembawo adanena kuti kafukufuku wawo wam'mbuyomu adawonetsa kuti njira yawo ingachepetse mphamvu yosonkhanitsirakryptonindi xenon pafupifupi 30 peresenti. Ngati izi ndi zoona, ndiye kuti asayansi a mafakitale ndi okonda kuwala kwa fulorosenti adzakhala ndi zambiri zoti azinyadira.

Dr. Alex Berezov ndi PhD microbiologist, wolemba sayansi ndi wokamba nkhani yemwe amagwiritsa ntchito pseudoscience ku American Council on Science and Health. Iyenso ndi membala wa bungwe la olemba ku USA TODAY komanso wolankhula mlendo ku The Insight Bureau. M'mbuyomu, anali mkonzi woyambitsa RealClearScience.
Bungwe la American Council on Science and Health ndi bungwe lofufuza ndi maphunziro lomwe likugwira ntchito pansi pa gawo 501(c)(3) la Internal Revenue Code. Zopereka sizilipira msonkho konse. ACSH ilibe zopereka. Timapeza ndalama makamaka kuchokera kwa anthu ndi maziko chaka chilichonse.
