摘要：

We report the synthesis of aggregated diamond nanorods (ADNRs) from fullerene C-60 at 20(1) GPa and 2200 degrees C using a multianvil apparatus. Individual diamond nanoroads are of 5-20 nm in diameter and longer than 1 mu m. The x-ray and measured density of ADNRs is similar to 0.2%-0.4% higher than that of usual diamond. The extremely high isothermal bulk modulus K-T=491(3) GPa [compare to K-T=442(4) GPa of diamond] was obtained by in situ x-ray diffraction study. Thus, ADNRs is the densest among all carbon materials and it has the lowest so far experimentally determined compressibility. (c) 2005 American Institute of Physics.
