英国著名的Nature杂志最近发表了中国和日本两个独立的研究小组的报告,宣布合成最小的稳定碳纳米管,其直径仅0.4nm。设在筑波城的日本电气公司(NEC)的研究小组发现这种直径为0.4nm的小管位于含18个同心壳的纳米管的核心。他们通过将一根石墨棒在氢气中放电弧蒸发而产生该
The famous British journal Nature recently published a report by two independent research groups from China and Japan, announcing the synthesis of the smallest stable carbon nanotubes with a diameter of only 0.4 nm. A research group at Nippon Electric Corporation (NEC) in Tsukuba city found that a 0.4 nm diameter tube was located at the core of 18 concentric-shell nanotubes. They created this by firing a graphite rod in a hydrogen arc
