The Macromolecular, Supramolecular and Nanochemistry program of the NSF Division of Chemistry and the Solid State and Materials Chemistry program of the Division of Materials Research supports the research project of Prof. Alexander Wei of Purdue University. Prof. Wei and his students will fabricate annular magnetic nanostructures on metal surfaces and focus primarily on the synthesis of cobalt nanometric rings. The group will investigate fundamental aspects of nucleation and growth in nanostructure synthesis and optimize the reaction conditions to realize templated anisotropic growth of the cobalt nanostructures. Cobalt nanostructures exhibit superb magnetic properties and controlling their dimensions at the nanometer scale will potentially led to the development of improved magnetic nanodevices. The project will also lead to the development of new concepts for non-voltaic memory and data processing, with potential for high density in 3D. The project will provide excellent training opportunities to undergraduate and graduate students in a highly interdisciplinary area at the forefront of science and nanotechnology.

NSF化学部的大分子、超分子和纳米化学项目以及材料研究部的固态和材料化学项目支持普渡大学亚历山大魏教授的研究项目。魏教授和他的学生将在金属表面上制造环形磁性纳米结构，并主要关注钴纳米环的合成。该小组将研究纳米结构合成中的成核和生长的基本方面，并优化反应条件，以实现钴纳米结构的模板化各向异性生长。钴纳米结构具有优异的磁性，在纳米尺度上控制其尺寸将有可能导致改进的磁性纳米器件的发展。该项目还将导致非伏打存储器和数据处理的新概念的开发，具有3D高密度的潜力。该项目将在科学和纳米技术的前沿高度跨学科领域为本科生和研究生提供极好的培训机会。
