Waxyaabaha Dhulka dhif ah(Reese) sidaLanthanumiyoneqymiumWaa qaybo muhiim u ah qalabka elektiroonigga ah ee casriga ah, oo laga soo qaado taleefannada gacanta iyo saqafka qoraxda ee satalaytiga iyo gawaarida korantada. Birahaan culus waxay ku dhalataa hareerahaaga oo dhan, in kasta oo ay ku jiraan tiro yar. Laakiin baahida ayaa sii kordheysa oo sababtoo ah waxay ku dhacaan ururinta hoose ee noocan oo kale ah, habab dhaqameed ee tigidhka waxay noqon karaan kuwo aan waxtar lahayn, jawiga deegaanka, iyo waxyeelada caafimaadka shaqaalaha.

Hadda, iyada oo maalgelinta laga helo hay'adda Mashaariicda Difaaca Sare ee Sare ee Mashruuca Baadhitaanka (Darpa) Barnaamijyada 'Embers', San Diego States-ka Sanadka Gobolka (San Diego States) waxay horumarinayaan hababka soosaarka ee horumarsan ee leh hababka soosaarka ee horumarsan iyadoo ujeeddadu tahay kor u qaadida sahayda gudaha ee Rees.

"Waxaan isku dayeynaa inaan horumarinno hanaan cusub oo dib u soo kabashada oo ah bey'ad saaxiibtinimo oo waara,"

Si tan loo sameeyo, cilmi-baarayaashu waxay ku dhex dhici doonaan bakteeriyada dabiiciga ah ee waxtarka leh ee wax dawada ka cunaya ee ku nool xaalado aad u daran si ay u qabtaan res vieedyada.

"Waxay u baahan yihiin waxyaabo badan oo dhulka ah si ay uga dhigaan mid ka mid ah falcelinta enzymatic furaha ah ee dariiqyadooda dheef-shiid kiimikaadka," ayuu yiri Kallyuzhyaya.

Rees waxaa ka mid ah waxyaabo badan oo Lanthanide miiska xilliyeed. Iyada oo lala kaashanayo Jaamacadda Kaliforniya ee California, Shaybaarka Qaranka ee Berkeled Saddexaad (PNNL), cilmi-baarayaasha SSSU waxay qorsheynayaan inay ka beddelaan injineerka geedi socodka bayoolojiga ee u oggolaanaya bakteeriyada inay ka goostaan ​​metaalka jawiga. Fahmitaanka nidaamkan ayaa ogeysiin doona abuurista borotiinnada naqshadeeye ee isku-dhafka ah ee ku xidha si gaar ah oo noocyo kala duwan ah oo noocyo kala duwan ah oo ah laantnasides, sida uu sheegayo bayoolajigii Yooxanaa. Kooxda PNNL waxay cadeyn doontaa go'aamada hidde-wadayaasha ee xagjirnimada iyo dib u soo ururinta bakteeriyada, ka dibna ku garto uteeradooda.

Kooxda ayaa ka dib wax ka badali doonta bakteeriyada inay soo saarto borotiinnada birta ah ee dusha sare ee unugyadooda, ayuu yiri jacayl.

Rees waa mid aad u badan oo dabacsan, wax soo saarka qashinka ee biraha birta ah, sida aluminium.

Kallyuzhyaya ayaa yidhi: "Dabaqadayda

Si loo daahiriyo loona soo qaado cawska gudaha, kuwan waaweyn ee dhagaxa iyo dhagaxyada jajaban waxaa lagu dhex mari doonaa bakteeriyada wax laga beddelay, oo u oggolaanaya borotiinka naqshadeeysan ee bakteeriyada si ay u xalliyaan cawska. Sida bakteeriyada aan jeclahay ee metlane-jecel ee u adeegta sidii qaabkooda, bakteeriyada la hagaajiyay waxay u dulqaadan doontaa xag-jirnimada DH, heerkulka iyo salaanta, xaaladaha laga helo dabada miinada.

Baarayaasha waxay iskaashi la yeelan doonaan lammaanaha warshadaha, Xarunta Cilmi-baarista Palo ee Palo Alto (Parc), shirkad Xerox, oo ku socota Biilaha Been abuurka, Sorbent Agag si loogu isticmaalo biofilter. Tiknoolajiyaddan wax-ku--bixintantu waa qiime jaban oo la miisaami karo oo waxaa la saadaalinayaa inay ka dhalato keyd muhiim ah markii si ballaaran loogu dabaqo soo celinta macdanta.

In addition to testing and optimizing the biofilter, the team will also have to develop methods for collecting the purified lanthanides from the biofilter itself, according to environmental engineer Christy Dykstra. Cilmi baadhayaashu waxay isku urursadeen shirkad bilow ah, dabada Phoenix, si ay u tijaabiyaan oo ay u habeeyaan hawsha soo kabashada.

Sababta oo ah yoolku waa in la sameeyo hanaan ganacsi ahaan macquul ah laakiin hab-nololeed ah oo loogu talagalay soo saarista Rykstra, Dykstra iyo dhowr ka mid ah wada-hawlgalayaasha mashruuca ayaa la barbar dhigayaa tikniyoolajiyadda kale ee soo kabashada Lanthanides, laakiin sidoo kale saamaynta deegaanka.

"Waxaan filaynaynaa inay wax badan kala taqaano kharashyo badan oo ku saabsan kharashyada deegaanka iyo tamarta deegaanka ee deegaanka marka la barbar dhigo waxa hada la isticmaalo," ayuu yiri Dykstra. "Nidaam sidan oo kale ah ayaa noqon kara mid ka mid ah nidaamka biofittration-ka aan caadiga ahayn, oo leh tamar yar oo tamar ah. Ka dibna,, in si yar oo loo isticmaalo dareeraha bey'ada bey'ada ugu waxyeellada leh iyo waxyaabo la mid ah. Qaab badan oo howlo leh oo hadda ah ayaa istcimaali kara runtii qalad adag oo aan ahayn xayndaab-saaxiibtinimo. "

Dykstra waxay sidoo kale xustaa in tan iyo bakteeriyada ay iskood isu muujiyaan, tiknolojiyadda ku saleysan khaa'inka ayaa ah is-cusbooneysiin, "halka aan si joogto ah u isticmaalno qaab kiimikaad,"

"Xitaa haddii ay wax yar ka bixin doonto, laakiin waxoogaa wax yeeleysa deegaanka, taasi micnaheedu waa macno," ayuu yiri Kallyuzhyaya.

Ujeeddada Mashruuca DARPA-ga ee Daaripa waa in la bixiyo caddeynta tikniyoolajiyadda dib-u-soo kabashada ee loo yaqaan 'Ree-ka soo kabashada' ee Do-Diverw.

Waxay intaas ku dartay in mashruucu uu siin doono SSU-da ardayda fursad u leh inay kaqaybqaataan cilmi-baaris kaladuwan "oo eeg sida fikradaha u kori karaan fikradaha kaliya ee banaanbaxyada."
