Gulu la ofufuza a ku yunivesite ya Curtin, yunivesite ya Western Australia, ndi China University of Geoscience apeza kuti golide wochepa kwambiri akhoza kutsekeredwa.mkati mwa pyrite, kupangitsa ‘golide wa chitsiru’ kukhala wamtengo wapatali kuposa dzina lake.
Mupepalalofalitsidwa mu magaziniGeology,asayansi akupereka kusanthula mozama kuti amvetse bwino malo a mineralogical a golide wotsekeredwa mu pyrite.Ndemanga iyi - iwo amakhulupirira - ikhoza kubweretsa njira zambiri zochotsera golide.
Malinga ndi gululi, mtundu watsopano wa golide 'wosaoneka' sunadziwike m'mbuyomu ndipo umangowoneka pogwiritsa ntchito chida chasayansi chotchedwa atom probe.
M'mbuyomu otulutsa golide amatha kupeza golide mkatipyritekaya ndi ma nanoparticles kapena aloyi yagolide ya pyrite, koma zomwe tapeza ndikuti golide amathanso kukhala ndi vuto la nanoscale crystal, kuyimira mtundu watsopano wa golide 'wosawoneka', "adatero wofufuza wamkulu Denis Fougerous m'mawu ake atolankhani.
Malinga ndi a Fougerous, kristaloyo ikakhala yopunduka kwambiri, m’pamenenso golideyo amatsekeredwa m’zilema.
Wasayansiyo adalongosola kuti golideyo amakhala ndi zolakwika za nanoscale zomwe zimatchedwa dislocations - zocheperapo zana limodzi kuposa kukula kwa tsitsi la munthu - ndichifukwa chake zitha kuwonedwa pogwiritsa ntchito atomu probe tomography.
Kutsatira zomwe adapeza, Fougerous ndi anzake adaganiza zoyang'ana njira yomwe imawalola kuti atenge chitsulo chamtengo wapatalicho pogwiritsa ntchito mphamvu zochepa kusiyana ndi njira zamakono zogwiritsira ntchito oxidizing.
Kusankha leaching, komwe kumaphatikizapo kugwiritsa ntchito madzimadzi kuti asungunuke golide kuchokera ku pyrite, kumawoneka ngati chisankho chabwino kwambiri.
"Sikuti ma dislocations amakoka golide, komanso amakhala ngati njira zamadzimadzi zomwe zimathandiza kuti golide "awonongeke" popanda kukhudza pyrite yonse," adatero wofufuzayo.
