日本在纳米这一高新技术领域应用开发研究取得多方面进展 ,不少小型风险投资企业非常活跃 ,发展步伐加快。与基础研究相比 ,日本最重视的是应用研究 ,尤其是纳米新材料研究。不久前 ,科学家矢田光德使用铒、铥等四种稀土元素合成了纳米管 ,但纳米材料目前仍以碳材料为主。除了 Japan made many progress in the application and development of nano-high-tech fields. Many small-scale venture capital enterprises are very active and their pace of development is accelerating. Compared with basic research, Japan is the most important application of research, especially nano-materials research. Not long ago, scientist Yada Makoto made use of four kinds of rare earth elements such as erbium and acenaphthene to synthesize nanotubes, but the nanomaterials are still based on carbon materials. apart from
