Common Atomic Force Microscopy (AFM) Techniques suffer from a number of fundamental difficulties limiting their usefulness in quantifying nanoscale interactions. The goal of this CAREER project at Wayne State University is to apply a novel AFM technique based on fiber interferometry and off-resonance, ultra-small amplitude operation to study important questions of the nanomechanics of individual atoms and molecules on surfaces. This includes the manipulation of single atoms and molecules, atomic scale energy dissipation, atomic bonding as a function of controlled tip and surface chemistry, atomic relaxation, and the relationship between AFM and Scanning Tunneling Microscopy (STM) imaging. These questions, while of a fundamental nature, are crucial for the rational development of future atomic/molecular scale nanosystems. Combined with this study is an integrated outreach program targeting parents of school age children with a series of lectures and demonstrations designed to illustrate the excitement of scientific research and raise awareness of scientific careers as fulfilling career choices for their children. This outreach program will be conducted in collaboration with local schools and two local science museums. The future of Nanotechnology lies in the controlled manipulation of single atoms and molecules. This lofty goal can only be achieved if we gain solid knowledge of the mechanics of single atoms and molecules. This CAREER project at Wayne State University is designed to use a novel instrument, a "Sub-Angstrom Amplitude Atomic Force Microscope", to measure forces while manipulating single atoms and molecules, and to conduct complementary and important experiments on the 'nanomechanics' of single atoms. These studies will provide crucial knowledge necessary for the design of future nanometer scale devices. Research will involve graduate and undergraduate students at Wayne State University. In addition, the project includes a significant outreach component whereby parents of local school students are provided with an insight into the excitement of scientific research, the stimulating life of a university researcher, and the latest findings in Physics and Nanotechnology. This program, provided through local schools and two local science museums, is designed to raise awareness of scientific careers as fulfilling career choices, and to enlighten the participants about the importance of fundamental and applied science in our society.

常见的原子力显微镜（AFM）技术遭受了一些基本的困难，限制了它们在量化纳米级相互作用的有用性。韦恩州立大学的这个CAREER项目的目标是应用一种基于光纤干涉和非共振、超小振幅操作的新型AFM技术来研究表面上单个原子和分子的纳米力学的重要问题。这包括单个原子和分子的操纵，原子尺度的能量耗散，原子键合作为受控尖端和表面化学的函数，原子弛豫，以及AFM和扫描隧道显微镜（STM）成像之间的关系。这些问题，而一个基本的性质，是未来原子/分子尺度的纳米系统的合理发展至关重要。与这项研究相结合的是一个针对学龄儿童家长的综合推广计划，该计划包括一系列讲座和演示，旨在说明科学研究的兴奋点，并提高人们对科学职业的认识，使其成为子女的职业选择。这项推广计划将与当地学校和两个当地科学博物馆合作进行。纳米技术的未来在于对单个原子和分子的可控操纵。这个崇高的目标只有在我们获得了单个原子和分子力学的坚实知识的情况下才能实现。韦恩州立大学的这个CAREER项目旨在使用一种新颖的仪器，“亚埃振幅原子力显微镜”，在操纵单个原子和分子的同时测量力，并对单个原子的“纳米力学”进行补充和重要的实验。这些研究将为未来纳米尺度器件的设计提供必要的关键知识。研究将涉及韦恩州立大学的研究生和本科生。此外，该项目还包括一个重要的外展部分，使当地学生的家长能够深入了解科学研究的兴奋，大学研究人员的刺激生活以及物理学和纳米技术的最新发现。该计划通过当地学校和两个当地科学博物馆提供，旨在提高人们对科学职业作为实现职业选择的认识，并启发参与者了解基础科学和应用科学在我们社会中的重要性。
