C60, the most important member of the fullerenes family, has been widely studied including size effect, crystal structure, photoluminescence and impact of doping, etc.[1-3] As a kind of doped fullerenes, solvated C60 has attracted lots of interests to synthesis and property investigations, owing to its unique properties that different from pristine C60.[4,5] Due to the existence of the solvent molecules,the solvates always have different crystal structure, such as orthorhombic, hexagonal, tetragonal, etc.[6-8] Here, we regard an orthorhombic C60 solvate with needlelike shape as our research object.The C60 solvate is prepared by evaporating C60 solution.

高温高压下锆钛二元合金材料的相变、状态方程以及强度变化规律是实验和理论关注的研究热点.本文采用第一性原理方法研究了锆钛合金晶体结构的结合能、点阵常数、相变、弹性模量以及强度等物理量.计算结果显示,晶格常数以及弹性常数与实验值符合较好.同时得出,锆钛合金ω→β相变压为35GPa,随着压力的增加,β相的稳定性显著提高;ω→α相变发生在55GPa~89GPa,而α→β相变发生在20GPa.
