Nobel z fizyki za przełomowy materiał (wideo)
Szybsze komputery i przejrzyste ekrany dotykowe mogą pojawić się na rynku dzięki grafenowi. Jest to supermocny, cienki materiał odkryty w roku 2004. Wczoraj nagrodę Nobla z fizyki otrzymali Andriej Gejm i Konstantin Nowosiołow za przełomowe eksperymenty związane z grafenem.
