据悉,今年6月10日,北京大学化学系和物理系研究小组研制成功了碳60材料,经红外、核磁、质谱等方法测定,该材料的各项数据均接近国际水平。碳60,又称足球烯,是石墨、金刚石之后新发现的碳的第三种同素异形体。由于它具有含60个碳原子的稳定的球形结构,有可能成为新型的润滑剂或催化剂基体。若掺少量碱金属,碳60材料又具有超导性能。继碳60的合成成功,在7月9日,北京大学研究小组又与中科院物理研究所合作研制成功K_3C_(60),超导起始温度为17.9K。K_3C_(60)是一种碳60的碱金属化合物,一种新型的高温超导体,它的超导转变温度远高于已发现的各种有机超导体。上述两项最新成果说明了我国在高温超导研究方面继续走在世界前列。
It is reported that on June 10 this year, Peking University Department of Chemistry and Physics Department successfully developed a carbon 60 materials, by infrared, nuclear magnetic resonance, mass spectrometry and other methods, the material of the data are close to international standards. Carbon 60, also known as soccer alkene, is the third allotrope of carbon newly discovered after graphite and diamond. Due to its stable, spherical structure with 60 carbon atoms it is possible to become a new lubricant or catalyst matrix. If doped with a small amount of alkali metal, carbon 60 material has superconducting properties. Following the successful synthesis of carbon 60, on July 9, the Peking University research group and the Institute of Physics, Chinese Academy of Sciences successfully developed K_3C_ (60), the superconducting start temperature of 17.9K. K_3C_ (60) is a kind of carbon 60 alkali metal compound, a new type of high temperature superconductor. Its superconducting transition temperature is much higher than that of various organic superconductors. The two latest achievements above show that our country continues to take the lead in the field of HTS research in the world.
