This Materials World Network project builds up on already established successful interaction between the research laboratories of Prof. Pulickel M. Ajayan (Rensselaer Polytechnic Institute; RPI) and Prof. Mauricio Terrones (Instituto Potosino de Investigacin Cientfica y Tecnolgica; IPICyT, Mexico) and aims towards the fabrication of new materials and devices using nitrogen doped carbon nanotubes (CNx) and other hybrid structures based on nanotubes. In addition to CNx material, the investigators explore the synthesis of novel nanotubes doped with other elements, for example, phosphorous. The research focuses on the fabrication of new products and prototypes such as sensors and polymer composites using CNx nanotubes and other doped nanotubes. During the previous three years of this project, the researchers demonstrated that the presence of nitrogen within CNx nanotubes plays an important role in the dispersion of CNx nanotubes, prior to mixing with polymers. In addition, results showed that the nitrogen containing surfaces are also easy to functionalize chemically. This research addresses the composite fabrication and additionally, will examine CNx nantubes as gas sensors. At IPICyT, there has been progress that allows production of bulk quantities of CNx nanotubes. At RPI the focus is on the fabrication and characterization of composite materials with CNx nanotubes. In addition, this work explores techniques to assemble CNx nanotubes and produce nanotube networks and junctions. Also, the work examines new structures of nanotubes with dopants such as phosphorous and explores the unique structural and electrical properties of these materials.During the next three years of continuation of this project, the researchers utilize the momentum generated by the successful earlier collaboration to increase student and personnel exchanges and the use of bilateral facilities in nanofabrication to achieve further results in carbon nanotube research. Students from the two countries have the opportunity to merge interdisciplinary expertise and participate in research at the cutting edge of materials science and nanotechnology. Mexican students and young scientists visit the US laboratory to engage in nanofabrication, development of sensors and polymer composites, and learn about the working environment in US laboratories in general. Similarly, undergraduates and graduate students from the US visit IPICyT and collaborate with Mexican scientists. The education efforts of the investigators include curriculum development activities in addition to lectures and seminars.

该材料世界网络项目建立在 Pulickel M. Ajayan 教授（伦斯勒理工学院；RPI）和 Mauricio Terrones 教授（Instituto Potosino de Investigacin Cientfica y Tecnolgica；IPICyT，墨西哥）研究实验室之间已建立的成功互动基础上，旨在使用氮掺杂碳纳米管制造新材料和器件 （CNx）和其他基于纳米管的混合结构。除了 CNx 材料之外，研究人员还探索了掺杂其他元素（例如磷）的新型纳米管的合成。该研究的重点是使用 CNx 纳米管和其他掺杂纳米管制造新产品和原型，例如传感器和聚合物复合材料。在该项目的前三年中，研究人员证明，CNx 纳米管中氮的存在对于 CNx 纳米管与聚合物混合之前的分散起着重要作用。此外，结果表明含氮表面也易于化学功能化。这项研究涉及复合材料制造，此外还将研究 CNx 纳米管作为气体传感器。 IPICyT 在批量生产 CNx 纳米管方面取得了进展。 RPI 的重点是 CNx 纳米管复合材料的制造和表征。此外，这项工作还探索了组装 CNx 纳米管并生产纳米管网络和连接的技术。此外，这项工作还研究了含有磷等掺杂剂的纳米管的新结构，并探索了这些材料的独特结构和电学特性。在该项目接下来的三年持续时间里，研究人员利用早期成功合作所产生的动力，增加学生和人员交流，并利用双边纳米制造设施，在碳纳米管研究方面取得进一步成果。两国的学生有机会融合跨学科专业知识，参与材料科学和纳米技术的前沿研究。墨西哥学生和青年科学家参观美国实验室，从事纳米加工、传感器和聚合物复合材料的开发，并了解美国实验室的总体工作环境。同样，来自美国的本科生和研究生访问 IPICyT 并与墨西哥科学家合作。调查人员的教育工作除了讲座和研讨会之外还包括课程开发活动。
