The Nanoscale Science and Engineering Center entitled Center of Integrated Nanomechanical Systems (COINS) is a partnership between UC Berkeley, Caltech, Stanford and UC Merced. This team will interact closely with partners from national laboratories (Sandia and Lawrence Berkeley National Labs) and industry (HP, Nanosys, IBM, GE, Intel, Honeywell, and ChevronTexaco). The NSEC includes 27 investigators from 7 departments. COINS has a focus on molecular and nanometer level mechanics at the interface of hard and soft matter, with five thrusts centering on an "element-to-device-to-system" research strategy: (I) Key Nanomechanical Building Blocks; (II) Theoretical Simulation of Nanomechanics; (III) Mechanical. Behavior of Nanostructure Elements; (IV) Instrumentations for Nanomechanical Measurements; and (V) Nanomechanical System Integration. Chemical synthesis (Thrust I) plays a significant role in generating key nanomechanical building blocks including synthetic/biological molecules, nanotubes and nanowires. Computational schemes at the atomistic and continuum levels (Thrust II) will be developed to address the scaling effects observed in the experiments and offer theoretical insight and guidance for the experimental works in COINS. Research Thrust III probes the intrinsic mechanical behaviors of the key nanomechanical building blocks produced in Thrust I. Optical tweezers, AFM/STM and in-situ TEM are used to systematically study the quality factor, strength, friction, wear, and energy dissipation at nanometer scale. In addition, novel nanomechanical testing procedures and devices (Thrust IV) will be designed in order to assess the mechanical properties of the nanomechanical building blocks. These include AFM systems for RF resonator characterization, MEMS-based testing platforms for nanostructures, and non-contact nanomechanical instrumentation. Thrust V will tackle the system integration issues utilizing nanomechanical units developed and characterized in the other four thrusts. Here, the bottom-up synthetic techniques will substantially leverage the conventional top-down approaches for NEMS fabrication. Concepts of selforganization will be adapted from nature in intriguing biological mechanical systems. Thrust V will ultimately enable the integration of individual devices into fully functional nanomechanical systems capable of performing highly complex tasks. All five thrust areas will be represented at Berkeley; Stanford University will contribute to Thrusts II, III, and IV, and Cal Tech will contribute to Thrusts III, IV, and V.The Center has broader impacts in addressing the real-time study of nanotechnology asa leading edge system of innovation; the influence of the intellectual property system; standard-setting; control on emerging nanotechnological industries; industrial location, both within the United States and around the world; and the management of risks-both real risks and the perception of risks created by potentially disruptive technologies.Educational efforts within COINS will not only encompass the scientific themes proposed for theCenter, but also address the broader need of workforce training in the emerging world of nanoscale science and technology. COINS includes an education program involving the general public, high school and college students to attract them to the diverse educational paths and career opportunities. A "Capital Science" workshop program will be designed to help state legislators and their staff make better policy decisions on issues with a significant scientific and technical dimensions. As a result of the NSF IGERT and the Designated Emphasis in Nanoscale Science and Engineering, Berkeley is in the process of developing a number of new graduate and undergraduate courses in nanoscience. In particular, an introductory course on nanoscience and a course on nanomechanics will be developed. In addition, COINS will support education and outreach activities at UC Merced, which will open in August 2005, and is likely to qualify as a Hispanic-Serving Institution. The Chancellor of UC Merced has set a goal to enroll half of the student body from the Central San Joaquin Valley, an economically and educationally underserved area. Fifty-three percent of the students demonstrating an interest in UC Merced were from households with incomes of $40,000 or less. We will focus on creating online modules that cover key concepts in nanoscience. Undergraduates from UC Merced and partner community colleges will construct the modules, under the supervision of graduate students and faculty. This experience will also include time in residence in the laboratories of faculty participants. This will enable their exposure to university research early on in their academic careers. The courseware developed in this effort will be used in K-12 outreach efforts that UC Merced faculty will undertake in the lower Central Valley. In addition, a nanoscale technology component will be incorporated into the Environmental Engineering program, one of the opening majors for UC Merced.

纳米科学与工程中心名为集成纳米机械系统中心（COINS），是加州大学伯克利分校、加州理工学院、斯坦福大学和加州大学默塞德分校的合作伙伴关系。该团队将与来自国家实验室（桑迪亚和劳伦斯伯克利国家实验室）和工业界（惠普、纳诺sys、IBM、通用电气、英特尔、霍尼韦尔和雪佛龙德士古）的合作伙伴密切互动。NSEC包括来自7个部门的27名调查人员。COINS专注于硬物质和软物质界面的分子和纳米级力学，围绕“元素到设备到系统”的研究策略，有五个重点：(1)关键的纳米力学构建模块；（二）纳米力学理论模拟；(3)机械。纳米结构元素的行为；纳米机械测量仪器；（五）纳米机械系统集成。化学合成（Thrust I）在生成关键的纳米力学构件（包括合成/生物分子、纳米管和纳米线）方面发挥着重要作用。将开发原子和连续体水平（Thrust II）的计算方案，以解决实验中观察到的尺度效应，并为硬币实验工作提供理论见解和指导。研究推力III探讨了推力i中生产的关键纳米力学构件的内在力学行为。利用光学镊子、AFM/STM和原位透射电镜系统研究了纳米尺度下的质量因子、强度、摩擦、磨损和能量耗散。此外，将设计新的纳米力学测试程序和设备（Thrust IV），以评估纳米力学构建块的力学性能。其中包括用于射频谐振器表征的AFM系统，用于纳米结构的基于mems的测试平台，以及非接触式纳米机械仪器。推力V将利用在其他四个推力中开发和表征的纳米机械单元来解决系统集成问题。在这里，自下而上的合成技术将充分利用传统的自上而下的方法来制造NEMS。自组织的概念将在有趣的生物机械系统中从自然界改编。推力V最终将使单个设备集成到功能齐全的纳米机械系统中，能够执行高度复杂的任务。所有五个重点领域的代表都将在伯克利；斯坦福大学将为第二、三、四推进项目做出贡献，加州理工学院将为第三、四、五推进项目做出贡献。该中心在解决纳米技术作为前沿创新系统的实时研究方面具有更广泛的影响；知识产权制度的影响；标准制定;对新兴纳米技术产业的控制；工业位置，无论是在美国境内还是在世界各地；以及对风险的管理——既包括真实风险，也包括对潜在破坏性技术所带来的风险的认知。硬币内的教育工作不仅包括为中心提出的科学主题，而且还解决了新兴的纳米级科学和技术世界中劳动力培训的更广泛需求。硬币包括一个涉及普通公众，高中和大学生的教育计划，以吸引他们多样化的教育途径和职业机会。一个“资本科学”研讨会项目的目的是帮助州议员及其工作人员在具有重大科学和技术层面的问题上做出更好的政策决定。由于NSF IGERT和纳米尺度科学与工程的指定重点，伯克利正在开发一些新的纳米科学研究生和本科生课程。特别地，将开设一门纳米科学入门课程和一门纳米力学课程。此外，硬币将支持加州大学默塞德分校的教育和外展活动，这将于2005年8月开放，并有可能获得西班牙裔服务机构的资格。加州大学默塞德分校（UC Merced）的校长设定了一个目标，要从圣华金中部山谷（Central San Joaquin Valley）招收一半的学生，这是一个经济和教育都不发达的地区。对加州大学默塞德分校表现出兴趣的学生中，有53%来自收入在4万美元或以下的家庭。我们将专注于创建涵盖纳米科学关键概念的在线模块。来自加州大学默塞德分校和合作社区学院的本科生将在研究生和教师的指导下构建这些模块。这段经历还包括在教师参与者的实验室居住的时间。这将使他们在学术生涯的早期接触到大学研究。在这项工作中开发的课件将用于加州大学默塞德分校教师将在中央山谷下游开展的K-12外展工作。此外，纳米技术将被纳入环境工程项目，这是加州大学默塞德分校的开放专业之一。
