Chii chinobatsira graphene? Nyaya mbiri dzekushandisa dzinokubatsira kunzwisisa mukana wekushandisa graphene
Muna 2010, Geim naNovoselov vakahwina Mubairo weNobel mufizikisi nekuda kwebasa ravo pagraphene. Mubairo uyu wakasiya pfungwa huru kuvanhu vazhinji. Pamusoro pezvose, hazvisi zvese zvishandiso zvekuyedza zveNobel Prize zvakajairika setepi yekunamira, uye hazvisi zvese zvinhu zvekutsvagisa zvine mashiripiti uye zviri nyore kunzwisisa seR...Verenga zvakawanda -
