Momwemonso zomwe zimapangitsa kuti crusts kupanga mkati mwa teapot zingathandize kumvekanickelkuipitsidwa ndi madzi a m’nyanja, malinga ndi kafukufuku watsopano wochokera ku chilumba cha South Pacific cha New Caledonia.
Migodi ya Nickel ndi bizinesi yayikulu ku New Caledonia, ndipo chilumba chaching'onocho ndi chimodzi mwazomwe zimapanga zitsulo padziko lonse lapansi.Koma kuphatikiza kwa miyala ikuluikulu ndi mvula yamphamvu kumatanthauza kuti faifi wochuluka, komanso lead ndi zitsulo zina, zikuthera m’madzi ozungulira chisumbucho.Kuwonongeka kwa nickel kumatha kuwononga thanzi la munthu chifukwa kuchuluka kwake mu nsomba ndi nkhono kumawonjezeka pamene zikukwera m'magulu a chakudya.
Marc Jeannin, katswiri wokonza zachilengedwe payunivesite ya La Rochelle ku France, ndi anzake a pa yunivesite ya New Caledonia ku Noumea ankadabwa ngati angagwiritse ntchito njira yoteteza zitsulo za m’madzi kuti isawonongeke. nickel kuchokera m'madzi..
Mphamvu yamagetsi yofooka ikagwiritsidwa ntchito pazitsulo m'madzi a m'nyanja, imapangitsa kuti calcium carbonate ndi magnesium hydroxide zituluke m'madzi ndipo ma depositi a laimu amapangidwa pamwamba pa chitsulocho.Njirayi sinayambe yaphunziridwapo pamaso pa zonyansa zachitsulo monga faifi tambala, ndipo ofufuzawo ankadabwa ngati ma ion ena a nickel amatha kugwa.
Gululo linaponyera waya wachitsulo mumtsuko wamadzi ochita kupanga osakaniza ndi mchere wa NiCl2 ndikuyendetsa magetsi pang'ono kwa masiku asanu ndi awiri.Pamapeto pa nthawi yaifupi imeneyi, anapeza kuti pafupifupi 24 peresenti ya faifi tambala omwe analipo poyamba anali atatsekeredwa m’madipoziti.
Jeannine akuti iyi ikhoza kukhala njira yotsika mtengo komanso yosavuta yochotseranickel."Sitingathe kuthetsa kuipitsa konse, koma iyi ikhoza kukhala njira yochepetsera," adatero.
Zotsatira zake zinali zosayembekezereka, popeza kuthetsa kuipitsa sikunali pakati pa zolinga za pulogalamu yoyambirira yofufuza.Kafukufuku wamkulu wa Jeannin akuyang'ana njira zothanirana ndi kukokoloka kwa m'mphepete mwa nyanja - amafufuza momwe miyala ya miyala yamchere yokwiriridwa mu mawaya pansi pa nyanja imatha kukhala ngati simenti yachilengedwe, zomwe zimathandiza kukhazikika pansi pa madamu kapena magombe amchenga.
Jeannin adayambitsa ntchito ku New Caledonia kuti adziwe ngati mauna angatseke zitsulo zokwanira kuti zithandizire kuphunzira mbiri yanickelkuwonongeka pa tsamba.“Koma titazindikira kuti tingagwire faifi tambala wochuluka, tinayamba kuganizira za ntchito za mafakitale,” akukumbukira motero.
Christine Orians, katswiri wa sayansi ya zachilengedwe ku yunivesite ya British Columbia ku Vancouver, akuti njirayi singachotse nickel, komanso zitsulo zina zambiri."Kukhala ndi mpweya sikusankha," adauza Chemistry World."Sindikudziwa ngati zingathandize kuchotsa zitsulo zapoizoni zokwanira popanda kuchotsa zitsulo zomwe zingakhale zothandiza ngati chitsulo."
Komabe, Jeannine sada nkhawa kuti dongosololi, ngati litayikidwa pamlingo waukulu, lidzalanda nyanja zamchere zofunika kwambiri.3% yokha ya calcium ndi 0.4% ya magnesium yachotsedwa m'madzi panthawi yoyesera, ndipo akuti chitsulo chomwe chili m'nyanja chimakhala chokwanira kuti sichikhudza kwambiri.
Makamaka, Jeannin adanena kuti dongosolo loterolo likhoza kutumizidwa m'malo omwe ali ndi nickel yothamanga kwambiri, monga doko la Nouméa, kuti achepetse ndalama zomwe zimathera m'nyanja.Zimafunika kuyang'aniridwa pang'ono ndipo zimatha kulumikizidwa ndi magetsi ongowonjezwdwa monga ma solar panels.Nickel ndi zowononga zina zomwe zatsekeredwa pamlingo zitha kupezedwanso ndikusinthidwanso.
Jeannin adati iye ndi anzake akugwira ntchito ndi makampani ku France ndi New Caledonia kuti apange pulojekiti yoyesera kuti adziwe ngati dongosololi likhoza kukhazikitsidwa pamalonda.
Molekyu yotsika mtengo imapereka magwiridwe antchito ofanana ndi okwera mtengo omwe alipozitsulochothandizira, koma akukumana ndi mavuto akulu okhudzana ndi kukhazikika kwake.
Zopereka zokwana $210 miliyoni kuchokera kwa wabizinesi wa Moderna komanso Investor Tim Springer kuti athandizire kafukufuku wopitilira
