The Gordon Research Seminar and Conference (GRC) on "Thin Film and Small Scale Mechanical Behavior" will be held July 22-27, 2012, at Colby College in Waterville, Maine. This conference will be accompanied by the Gordon Research Seminar (GRS) on the same topic, to be held July 21-22, 2012 and aimed at enhancing active participation by graduate students and postdoctoral scientists. Financial support will help defray the conference fees and travel costs for invited speakers and discussion leaders as well as graduate students, post-docs and junior faculty members.The intellectual merit of this conference and seminar includes its highly trans-disciplinary nature, involving scientists with backgrounds in materials science and mechanics as well as colleagues from neighboring areas including condensed matter physics, electrical engineering, and biology. It is well established that the mechanical behavior of materials changes when they are geometrically confined to a small scale in at least one dimension. This may affect elastic, plastic and time-dependent deformation as well as degradation mechanisms such as fracture, fatigue, and wear. The fundamental mechanisms and scientific understanding of these changes, however, require continued investigation and are the subject of many research projects. The study of small scale mechanical behavior has benefitted from fundamental studies of physical mechanisms linked to materials science and engineering, reaching towards modern applications ranging from optical and microelectronic devices and nano- or micro-electrical mechanical systems (NEMS/MEMS) to devices for energy production and storage. This research area has always taken advantage of recent progress in atomistic and micromechanical modeling, as well as materials characterization and in-situ measurements at small length scales. As such, the study of small-scale mechanical behavior has fertilized many aspects of research in the fields of materials science and applied mechanics. Previous meetings have always led to intense discussions of new and unexpected results and observations, and in many cases new research and collaborations between attendees have been initiated. The 2012 Conference will continue to cover topics of lasting significance to the field such as deformation and fracture in small structures, advanced testing and characterization of materials at small length scales, and mechanical behavior of biological materials. In addition, it will highlight topics of growing importance. Particularly, emerging topics in the area of nanomechanical behavior of battery materials, will be highlighted.This GRC will have a broad impact on knowledge dissemination, stimulation of new ideas, and research collaborations. At previous GRC meetings on this topic, more than 100 international experts on the subject came together, with backgrounds in the areas described above and with a large portion of participants coming from Europe and Asia. Typically, more than half of the participants are students or young researchers from academia, national laboratories, and industry. The meeting brings these young scholars into direct contact with experts in the unique atmosphere of a GRC, stimulating not only their specific research interests, but even more importantly integrating them into a scientific community.The organizers have made a strong effort to invite speakers and discussion leaders and to support students who are diverse in background, gender, and race. Almost all of the invited speakers will be presenting for the first time at this GRC. The speakers will review the background and state-of-the-art for their subject and then present their newest and predominantly unpublished results. After all lectures, there will be ample time for questions and in-depth discussions. For this, the discussion leaders are very important and have been carefully chosen. They are either speakers from previous GRC meetings who can provide an overarching perspective and/or very experienced people who have done distinguished work and are adept at posing stimulating questions. It is further planned to have summary discussions at the end of each session.

戈登研究研讨会和会议(GRC)将于2012年7月22日至27日在缅因州沃特维尔的科尔比学院举行，主题为“薄膜和小规模机械行为”。本次会议将与戈登研究研讨会(GRS)一同举行，该研讨会将于2012年7月21-22日举行，旨在加强研究生和博士后科学家的积极参与。财政支持将用于支付特邀演讲者和讨论负责人以及研究生、博士后和初级教职员工的会议费和旅费。这次会议和研讨会的学术价值包括高度跨学科的性质，有材料科学和力学背景的科学家以及来自邻近领域的凝聚态物理、电气工程和生物学的同事。众所周知，当材料的几何尺寸限制在至少一维的小范围内时，材料的力学行为会发生变化。这可能会影响弹性、塑性和随时间变化的变形，以及断裂、疲劳和磨损等退化机制。然而，这些变化的基本机制和科学理解需要继续研究，并且是许多研究项目的主题。小规模机械行为的研究得益于与材料科学和工程相关的物理机制的基础研究，涉及从光学和微电子设备、纳米或微电子机械系统(NEMS/MEMS)到能量生产和存储设备的现代应用。这一研究领域一直利用原子和细观力学建模以及材料表征和小尺度原位测量的最新进展。因此，对小尺度力学行为的研究丰富了材料科学和应用力学领域的许多方面的研究。以前的会议总是导致对新的和意想不到的结果和观察结果的激烈讨论，在许多情况下，与会者之间开始了新的研究和合作。2012年会议将继续讨论对该领域具有持久意义的专题，如小型结构的变形和断裂、小型材料的先进测试和表征以及生物材料的力学行为。此外，它还将突出日益重要的主题。特别是电池材料纳米力学行为领域的新兴课题，将对知识传播、新想法的激发和研究合作产生广泛的影响。在以前关于这一主题的全球资源中心会议上，100多名国际专家聚集在一起，他们具有上述领域的背景，大部分与会者来自欧洲和亚洲。通常，超过一半的参与者是来自学术界、国家实验室和工业界的学生或年轻研究人员。会议让这些年轻学者在GRC独特的氛围中与专家直接接触，不仅激发了他们特定的研究兴趣，更重要的是将他们融入了一个科学社区。组织者做出了巨大努力，邀请演讲者和讨论领袖，并支持不同背景、性别和种族的学生。几乎所有被邀请的演讲者都将第一次在GRC上发言。演讲者将回顾其主题的背景和最新技术，然后介绍他们的最新成果，主要是未发表的成果。在所有讲座结束后，将有充足的时间提问和深入讨论。为此，讨论带头人非常重要，而且是经过精心挑选的。他们要么是以前GRC会议上的演讲者，他们可以提供总体观点，要么是非常有经验的人，他们做出了杰出的工作，并善于提出激动人心的问题。还计划在每届会议结束时进行总结讨论。
