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.

关于“薄膜和小尺度机械行为”的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。 此次会议将与将于 2012 年 7 月 21 日至 22 日举行的同一主题的戈登研究研讨会 (GRS) 同期举行，旨在加强研究生和博士后科学家的积极参与。 财政支持将有助于支付受邀演讲者和讨论负责人以及研究生、博士后和初级教员的会议费用和差旅费。本次会议和研讨会的智力价值包括其高度跨学科的性质，涉及具有材料科学和力学背景的科学家以及来自凝聚态物理、电气工程和生物学等邻近领域的同事。 众所周知，当材料在至少一个维度上被几何限制在小尺度内时，其机械行为会发生变化。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调查，并且是许多研究项目的主题。 小尺度机械行为的研究受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以及纳米或微米电气机械系统（NEMS/MEMS）到能源生产和存储设备的现代应用。 该研究领域始终利用原子和微机械建模以及小长度尺度的材料表征和原位测量方面的最新进展。 因此，小尺度力学行为的研究丰富了材料科学和应用力学领域研究的许多方面。 以前的会议总是会引发对新的和意想不到的结果和观察的激烈讨论，并且在许多情况下，与会者之间已经启动了新的研究和合作。 2012 年会议将继续涵盖对该领域具有持久意义的主题，例如小型结构的变形和断裂、小长度尺度材料的高级测试和表征以及生物材料的机械行为。 此外，它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主题将得到重点关注。此次 GRC 将对知识传播、新想法激发和研究合作产生广泛影响。 在之前关于该主题的 GRC 会议上，100 多名该主题的国际专家齐聚一堂，他们具有上述领域的背景，其中很大一部分与会者来自欧洲和亚洲。 通常，一半以上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。 此次会议让这些年轻学者在GRC独特的氛围中与专家进行直接接触，不仅激发了他们的具体研究兴趣，更重要的是让他们融入了科学界。主办方在邀请演讲者和讨论领袖方面下了大力气，并为不同背景、性别和种族的学生提供支持。 几乎所有受邀演讲者都是首次在本次 GRC 上发言。 演讲者将回顾其主题的背景和最新技术，然后展示他们最新且主要未发表的结果。 所有讲座结束后，将有充足的时间进行提问和深入讨论。 为此，讨论领导者非常重要，并且是经过精心挑选的。 他们要么是以前 GRC 会议上的发言人，可以提供总体观点，要么是经验丰富、工作出色并善于提出刺激性问题的人。 还计划在每场会议结束时进行总结讨论。
