CCR-0210176Crommie, MichaelThis proposal was received in response to the Nanoscale Science and Engineering initiative, NSF 01-157, category NIRT. The main objective of this project is to develop and characterize mechanical devices at the nanoscale. This will be performed through the creation of new, synthetic molecular machines purposefully designed in a molecule-by-molecule fashion. In order to achieve this goal an interdisciplinary team of researchers has been gathered that will engage in the following activities:1) chemically synthesize new molecules having tailored properties to be used as nano-machine components, 2) adhere newly synthesized molecules to prepared surfaces and demonstrate mechanical functionality, 3) combine photolithographic MEMS technology with carbon growth techniques to create electro-mechanically actuated molecular motors from carbon nanotubes. Two new categories of functional molecular assemblies are expected to result from this research. The first involves chemically engineered molecules designed with specific mechanical functions in mind. This research thrust will be supported by a strong chemical synthesis effort aimed at the development of new classes of molecules able to undergo conformational changes when triggered by an outside stimulus. The second category involves the engineering of multi-wall carbon nanotubes to form the basis of a new mechano-molecular technology. This effort is expected to culminate in the demonstration of the first functional nanotube motor.

CCR-0210176 Crommie，Michael该提案是响应NSF 01-157，类别NIRT的纳米科学与工程倡议而收到的。 该项目的主要目标是开发和表征纳米级的机械设备。 这将通过创造新的合成分子机器来实现，这些机器是以分子接分子的方式有目的地设计的。 为了实现这一目标，一个跨学科的研究团队已经聚集起来，将从事以下活动：1）化学合成具有定制特性的新分子，以用作纳米机器组件，2）将新合成的分子粘附到准备好的表面并展示机械功能，3）将联合收割机MEMS技术与碳生长技术相结合，从碳纳米管中创建机电驱动的分子马达。 两个新的类别的功能分子组装体，预计将导致从这项研究。 第一种涉及化学工程分子，其设计具有特定的机械功能。 这一研究重点将得到强有力的化学合成努力的支持，旨在开发能够在外部刺激引发时发生构象变化的新型分子。 第二类涉及多壁碳纳米管的工程设计，以形成新的机械分子技术的基础。 这项工作预计将在第一个功能性纳米管马达的演示中达到高潮。
