Magasi akanakakrypton uyexenonvari kurudyi rweperiodic tafura uye vane mashandisiro anoshanda uye akakosha. Semuenzaniso, ese ari maviri anoshandiswa pakuvheneka.Xenonndiyo inonyanya kukosha yezviviri, kuva nekushandiswa kwakawanda mumishonga uye teknolojia yenyukireya.
Kusiyana negasi rechisikigo, iro rakawanda pasi pevhu,kryptonuyexenoninoumba chikamu chiduku bedzi chemhepo yakapoteredza pasi. Kuti aaunganidze, magasi anofanira kupinda nemuzvikamu zvakati wandei zvesimba rinonyanya kusimba rinodaidzwa kuti cryogenic distillation, umo mweya unotorwa nekutonhodzwa kusvika -300 degrees Fahrenheit. Uku kutonhora kwakanyanya kunopatsanura magasi zvichienderana nekuvira kwawo.
A itsvakryptonuyexenontekinoroji yekuunganidza inochengetedza simba nemari inodiwa zvakanyanya. Vatsvakurudzi ikozvino vanotenda kuti vakawana nzira yakadaro, uye nzira yavo yakatsanangurwa mu Journal of the American Chemical Society.
Chikwata chakagadzira silicoaluminophosphate (SAPO), kristaro ine mapores madiki. Dzimwe nguva saizi yepore iri pakati pehukuru hwe krypton atomu uye axenonatomu. Mudikikryptonmaatomu anogona kupfuura nepamapores zviri nyore uku maatomu makuru exenon anonamira. Saka, SAPO inoita sesefa yemamorekuru. (Ona mufananidzo.)
Vachishandisa chiridzwa chavo chitsva, vanyori vakaratidza izvozvokryptoninopararira 45 times nekukurumidza kupfuuraxenon, ichiratidza kushanda kwayo mukuparadzaniswa kwegasi kune tembiricha yekamuri. Zvimwe zviedzo zvakaratidza kuti kwete chete iyo xenon yakatamburira kudzvanya nepakati pemapores madiki aya, asi zvakare yaida kushambadza pamakristasi eSAPO.
Mubvunzurudzo neACSH, vanyori vakati kuongorora kwavo kwekare kwakaratidza kuti nzira yavo inogona kuderedza simba rinodiwa kuunganidzakryptonuye xenon nezvikamu makumi matatu kubva muzana. Kana ichi chiri chokwadi, saka masayendisiti maindasitiri uye vanofarira chiedza chefluorescent vachave nezvakawanda zvekudada nazvo.
