In this paper, the Schrodinger equation for a 6-body system is studied. We solve this equation for the lithium nucleus by using a supersymmetry method with several specific potentials. These potentials are the Yukawa potential, the generalized Yukawa potential and the Hellmann potential. The results of our model for all calculations show that the ground state binding energy of the lithium nucleus with these potentials is very close to that obtained experimentally.

作者： Parisa Shad ghazvini Alzahra University Tehran Iran

Performance art in every region and country depends mainly on rules, customs, and beliefs of that particular society hence; this art enjoys diversity with respect to its forms and contents. In contemporary lran, with the emergence of new artistic movements, performance art incorporated more academic and enlighten aspects. New mass media and modern visual medium such as light, sound, moving, and changing images, video displays as well as application of new signs and symbols are some of the special characteristics of the contemporary performance art in Iran. Moreover, the performance art in Iran is not merely related to the contemporary era rather it encompasses a large number of traditional representations that have been prevalent among common people with much meaningful rules. Its popularity among common people is also a conceptual art which conveys a content-based meaning in a more dramatic sense. For centuries, the tradition of performance art in Iran can be observed in the rules of Ta＇aziehkhani （quite singing or passion play）, Shamayelgardani （icon handling）, Ru-howzi （performance on pool platform）, Marekegiri （mono drama）, Qhashoqhzani （spoon handling） and Aroosakgardani （puppet handling）. Aestheticism relying on traditional performing method is also the outcome of taste and elegance of common people. These performances have more folkloric aspects protruding from humane institutions and blended with their vernacular beliefs. In the traditional method of performance art, performers mostly enjoy their own taste and style and use handy means for executing their roles. In contemporary Iran, traditional method along with modern theme has been widespread among people particularly in villages and small townships although these are not called as art. The present study is an attempt to study existing challenges to modern and ancient art traditions as well as aesthetic values attributed to each of them.

在最近的几十年中,超级电容器(SC)已在电化学能量存储设备中获得了更为重要的地位。SC为使用寿命长的能量存储设备提供了可观的功率密度和令人满意的能量密度,适用于多种应用。因此,这些装置的进一步发展依赖于提供合适,低成本,环境友好和丰富的材料作为SC的电极活性材料。在用于SC的电极材料中,活性炭表现出优异的性能。它们具有优异的电化学效率,高比表面积,高吸附性,可调节的表面化学性质,快速的离子/电子传输,低成本和丰富的特性,使其成为SC电极的最佳材料。如果从生物质前驱体制备活性炭,则可以协同增强这些优势。由于生物质为可再生来源,低成本,便捷的加工过程以及对环境的友好性,研究者们将注意力集中在生物质上。在本文中,试图全面了解作为电化学储能装置的SC的基本原理。然后,对各种来源的生物质进行分类和分析。最后,讨论了这些生物质前驱体作为SCs电极材料的应用和活化技术。

硬碳、活性炭、碳纳米管(CNTs)、石墨烯、多孔炭和炭纤维等炭材料替代锂离子电池的石墨阳极是目前的研究热点。与石墨相比,这种材料已表现出更好的储锂电化学性能,但仍有待进一步发展空间。其中一种有效的方法是在炭材料结构中加入杂原子(例如氮),提高其作为锂离子负极时的电化学性能。本综述首先描述了氮掺杂如何对锂离子电池的性能产生积极影响,并举例说明了氮掺杂炭材料的优势。然后,比较了不同N掺杂炭材料中的X射线光电子能谱和扫描隧道显微镜的表征结果,通过统计分析了掺氮量对掺氮碳材料比容量的影响。
