据《C&EN》杂志报导,日本电气公司的研究人员最近发现了一种大量制备微小的管状碳结构的简易方法。此方法可使全世界的科学家都能不费力地得到这种管状碳结构以用于研究,因而有可能对材料科学产生意义深运的影响。管状碳结构是在1991年发现的。现在这类约数微米长的中空结构被科家们称为“纳米碳管”,因为它们的直径在几纳米的数量级上(1纳米为10~(-9)米,即1毫微米)。典型的 According to “C & EN” magazine, Nippon Electric Company researchers have recently discovered an easy way to produce large quantities of tiny tubular carbon structures. This method allows scientists around the world to effortlessly obtain this tubular carbon structure for research and thus has the potential to have a profound impact on material science. Tubular carbon structure was discovered in 1991. Now such hollow structures of about several micrometers in length are called “carbon nanotubes” by the scientists because their diameters are in the order of a few nanometers (10 to 9 meters for 1 nanometer, ie 1 nanometer). typical
