Individual diamond nanoroads are of 5-20 nm in diameter and longer than 1μm1μm. The x-ray and measured density of ADNRs is ∼0.2\%-0.4\%∼0.2\%-0.4\% higher than that of usual diamond. The extremely high isothermal bulk modulusKT=491(3)GPaKT=491(3)GPa [compare to KT=442(4)GPaKT=442(4)GPa of diamond] was obtained by in situx-ray diffraction study. Thus, ADNRs is the densest among all carbonmaterials and it has the lowest so far experimentally determined compressibility.}, language = {en} }
