Saynis yahanadu waxay horumariyaan hab deegaanka u saaxiibka ah si ay uga soo kabtaan REE dambaska duqsiga dhuxusha

Cilmi-baarayaal ka tirsan Machadka Teknolojiyadda ee Georgia, ayaa soo saaray hab fudud oo looga soo kabsado curiyeyaasha dhulka dhifka ah ee dambaska duqsiga ee dhuxusha iyadoo la isticmaalayo dareeraha ionic iyo ka fogaanshaha walxaha halista ah.
Warqad lagu daabacay joornaalka Sayniska Deegaanka & Teknolojiyada, saynisyahannadu waxay sharraxeen in dareeraha ionic loo arko inay yihiin kuwo deegaanka u xun oo dib loo isticmaali karo. Mid gaar ah, betanium bis (trifluoromethylsulfonyl) imide ama [Hbet] [Tf2N], waxay si door ah u milmaan oksaydhooyinka naadirka-dhulka ee oksaydhyada kale ee birta ah.
Sida saynis-yahannadu sheegeen, dareeraha ionic sidoo kale wuxuu si gaar ah ugu milmaa biyaha marka la kululeeyo ka dibna laba weji u kala baxa marka la qaboojiyo. Iyaga oo taas og, waxay dejiyeen si ay u tijaabiyaan haddii ay si hufan u doorbidi lahayd inay ka soo saaraan walxaha la rabo dambaska duqsiga dhuxusha iyo haddii si wax ku ool ah loo nadiifin karo, abuurista hannaan badbaado leh oo soo saara qashin yar.
Si taas loo sameeyo, kooxdu waxay ku sii daayeen dambaska duqsiga dhuxusha leh xal alkaline ah oo qalajiyey. Dabadeed, waxay ku kululeeyeen dambaska biyaha ku dheggan [Hbet][Tf2N], iyagoo abuuraya hal waji. Marka la qaboojiyo, xalalku waa kala tageen. Dareeraha ionic waxa uu ka soo saaray in ka badan 77% walxaha naadirka ah ee dhulka oo ka yimi walxo cusub,waxana ay ka soo kabsatay boqolkiiba intaa ka badan (97%) dambaska cimilada oo sanado badan ku qaatay balli kayd ah. Qaybta ugu danbeysa ee hawshu waxay ahayd in laga xayuubiyo curiyayaasha dhulka naadir ka ah dareeraha ionic oo leh aashito badhxan.
Cilmi-baadhayaashu waxay kaloo ogaadeen in ku darista betaine inta lagu guda jiro tillaabada leaching ay kordhisay cadadka walxaha dhifka ah ee dhulka laga soo saaro.
Scandium, yttrium, lanthanum, cerium, neodymium iyo dysprosium ayaa ka mid ahaa walxaha la helay.
Ugu dambayntii, kooxdu waxay tijaabisay dib-u-isticmaalka dareeraha ionic iyaga oo ku luqluqa biyo qabow si ay uga saaraan aashitada xad-dhaafka ah, iyaga oo aan wax isbeddel ah ku helin waxtarkeeda soo saarista iyada oo loo marayo saddex wareeg oo nadiifin ah.
"Habkan qashinka yar wuxuu soo saaraa xal qani ku ah walxaha dhifka ah ee dhulka, oo leh wasakh xaddidan, waxaana loo isticmaali karaa in dib loo warshadeeyo alaabta qaaliga ah ee tirada badan ee dambaska dhuxusha ee lagu hayo barkadaha kaydinta," ayay saynisyahannadu ku sheegeen hadal ay warbaahinta soo saareen.
Natiijooyinka ayaa sidoo kale muhiim u noqon kara gobollada dhuxusha soo saara, sida Wyoming, kuwaas oo raadinaya inay dib u soo nooleeyaan warshadahooda maxalliga ah iyada oo ay wajaheyso hoos u dhaca baahida shidaalka.
