Kunobva: Nhaurwa

Zvisingawanzo zvepasi zvinhu(Rees) kungeLanthanumuyeneodymiumIzvo zvakakosha zvikamu zvezvemagetsi zvemagetsi zvemazuva ano, kubva mbozhanhare uye masosi emwenje kune satellite uye mota yemagetsi. Aya masimbi anorema anoitika akatikomberedza, allbeit mune zvidiki zvidiki. Asi kudiwa kunoenderera mberi kusimuka uye nekuti zvinoitika munzvimbo dzakadzika dzakadaro, nzira dzechinyakare dzekubvisa zvisingaite, zvakatemerwa hutano hwevashandi.

"Tiri kuedza kukudziridza maitiro matsva ekupora izvo zvinoshamisa zvine hushamwari uye zvakaringana," akadaro Biologist uye mukuru muongorori Marina Kalyuzhnaya.

Kuti uite izvi, vatsvagiri vachatora muzvisikwa zvehutachiona hwehutachiona hunogara mumamiriro ezvinhu akanyanyisa kutora nzvimbo.

"Vanoda zvinhu zvisingawanzo kuitika kuti vaite imwe yekiyi enzymatic maitiro mune yavo nzira yeMetauro," akadaro Kalyuzhnaya.

Rees inosanganisira iyo yakawanda lanthanide zvinhu zve tafura yemaperi. Mukubatana neYunivhesiti yeCalifornia, Berkeley uye Pacific Northwest National Laboratori Kunzwisisa uku maitiro kuchazivisa kusikwa kweiyo synthetic gadzira mapuroteni anosunga neyakanyanya kufanana nemhando dzakasiyana dzemhando dzakasiyana, maererano neBiochemist John rudo. Chikwata chePNNL chinoratidza iyo genetic inosarudza yeiyo Extremophilic uye ree inounganidza mabhakitiriya, uye wozotaridza dziva ravo.

Chikwata chacho chinobva chichinja mabhakitiriya kuti ubudise mapuroteni esimbi-simbi pamusoro pemasero avo, akati rudo.

Rees are are denderedzwa mumuswe wangu, iyo magetsi zvigadzirwa zveimwe maOres yesimbi, senge aluminium.

"Misungo madiki ndeyekunyatso dongo iyo ichine zvinhu zvakawanda zvinobatsira mairi," akadaro Kalyuzhnaya.

Kuchenesa uye kuunganidza rezvinyorwa mukati, aya marara emvura uye matombo akapwanyika achamhanye kuburikidza ne biofilter aive akagadziridzwa, achibvumira mapuroteni ekugadzira pamusoro pebhakitiriya kuti asasungwa. Kufanana neboka rerudo rerudo raishanda sematomu avo, hutachiona hwakagadziridzwa huchanyatsotsunga naPh, tembiricha uye maseru, mamiriro ezvinhu anowanikwa mumuswe wangu.

Vatsvagiri vacho vanobatana neindasitiri, palo Alto Research Center (Parc), kambani yeXerox, kuBiorprint zvinyorwa zvekushandisa mune iyo biofilter. Iyi tekinoroji yebiritroji yakaderera-mutengo uye inokatyamadza uye inofungidzirwa kuti ive inokonzerwa nekuchengetedza kwakakura kana kuchinge kwave kuchishandiswa kupora kwemaminerari kupora.

Pamusoro pekuyedza uye kururamisa biofilter, timu ichave zvakare yekuvandudza nzira dzekuunganidza maLanthanides yakacheneswa kubva kuBiomiltter pachayo, maererano neInternet Christy Dykstra. Vaongorori vakabatana nekambani yekutanga, phoenix tailings, kuyedza uye kunatsiridza maitiro ekugadzirisa.

Nekuti chinangwa ndechekukudziridza hukama hwekutengesa asi hwakatipoteredzwa

"Isu tinofungidzira kuti zvaizove nezvakawanda zvakanakira nharaunda uye zvakaderera simba emari zvichienzaniswa nezviri kushandiswa," akadaro Dykstra. "Sisitimu yakaita seiyi ingangove yakawedzera yeiyo pesefitation system, ine shoma simba rinopinda. Uyezve, zvinonzwisisika, kushandiswa kushoma kwekuripo kwazvinoita zvinokuvadza zvimiro uye zvinhu zvakadaro. Maitiro mazhinji aripo anozoshandisa chaizvo nehasha uye asiri-akatodza hushamwari sol. "

Dykstra zvakare anotaura kuti sezvo mabhakitiriya anodzora pachavo, matekinoroji ezvemasango anozvivandudza, "asi kana taifanira kushandisa nzira yemakemikari, tingafanira kuunza zvimwe zvemakemikari."

"Kunyangwe kana zvichizorera zvishoma, asi hazvikuvadze nharaunda, izvo zvingave zvine musoro," akadaro Kalyuzhnaya.

Chinangwa cheiyo yeDarpa-mari projekiti ndeyokupa chiratidzo cheiyo-pfungwa inotungamirwa neyekudzorera Biology mumakore mana, iyo Kalyuzhnaya yakati ichada kuona uye kuyambuka-muchinjiko.

Akawedzera kuti chirongwa ichi chinopa vadzidzi veSDDU vakapedza kudzidza nemukana wekutora chikamu mukutsvagisa multidiscipparcy "uye ona kuti pfungwa dzinogona kukura sei kubva kune pfungwa munzira yese yekuratidzira."
