"Zvinhu zvinopihwa negraphene zvinogona kukanganisa zvakanyanya indasitiri yependi uye yekupfeka," anowedzera Velzin.“Kunyange zvazvo graphene ine mutengo wakakwira pagiramu pane zvimwe zvinowedzerwa, inoshandiswa mumari shoma uye inopa mabhenefiti akanaka zvekuti mutengo wenguva refu unokwanisika.gadzira graphene ?coatings??
"Izvi zvinhu zvinoshanda uye tinogona kuratidza kuti zvakanaka," Potts akawedzera."Kuwedzera graphene kune resipi, kunyangwe ishoma, inogona kupa shanduko."
