ORG: Materials Research SocietyTitle: Spring 2012 MRS Symposium RR: Molecules to Materials - Multiscale Interfacial Phenomena in Biological and Bio-inspired MaterialsINTELLECTUAL MERIT: Buried interfaces, i.e., interfaces that are occluded within the final composite material or functional structure, are crucial to a variety of biological processes and applications, including: (1) biological wet/dry adhesion in barnacles and geckos; (2) biological control over mineral growth and functional properties in biominerals; (3) tissue engineering; and (4) bio-lubrication, for example, in joints. Rational design of bio-inspired materials for applications from biomedicine to sensors and from catalysts to high toughness composites depends on a detailed understanding of the structure, chemistry, routes of assembly, mechanical properties, and wear-processes at these interfaces. With typical length scales ranging from the subnanometer to macroscopic dimensions and the complexities arising from the hybrid (hard/soft, organic/inorganic, etc.) character of these materials, the synthesis, simulation, and in situ functional characterization of such buried interfaces is a significant challenge. These challenges are currently addressed by experts from a number of communities that do not generally interact, as they currently have no common platform. The proposed symposium seeks to create such a multi-disciplinary forum and will actively recruit contributions from materials science, chemistry, biochemistry, medicine, biotechnology and state-of-the-art in situ characterization methodologies (e.g. Xray, electron imaging and tomography, spectroscopy, cryo-techniques).BROADER IMPACTS: The organizers are particularly interested in increasing the participation of underrepresented groups (women, minorities, and disabled persons), undergraduate institutions and historically black colleges and universities, and young researchers (students, postdocs, and young faculty). To this end, they are requesting funds to support the participation of these groups through travel grants for two exceptional female young faculty invited speakers and to up to nine others from these groups who have been accepted to make oral or poster presentations.

ORG：材料研究学会名称：2012年春季MRS研讨会RR：分子到材料-生物和生物启发材料中的多尺度界面现象智力优势：埋藏界面，即，封闭在最终复合材料或功能结构内的界面对于多种生物过程和应用是至关重要的，包括：（1）藤壶和壁虎中的生物湿/干粘附;（2）生物矿物中矿物生长和功能性质的生物控制;（3）组织工程;和（4）例如关节中的生物润滑。 从生物医学到传感器，从催化剂到高韧性复合材料，生物启发材料的合理设计取决于对这些界面的结构，化学，组装路线，机械性能和磨损过程的详细了解。 随着典型的长度尺度从亚纳米到宏观尺寸以及由混合物（硬/软，有机/无机等）引起的复杂性，这些材料的特性，合成，模拟，并在原位功能表征这样的埋界面是一个重大的挑战。 这些挑战目前由来自一些社区的专家处理，这些社区通常不互动，因为他们目前没有共同的平台。 拟议的专题讨论会旨在创建这样一个多学科论坛，并将积极招募材料科学、化学、生物化学、医学、生物技术和最先进的原位表征方法（例如X射线、电子成像和断层扫描、光谱学、低温技术）的贡献。 组织者特别感兴趣的是增加代表性不足的群体（妇女，少数民族和残疾人），本科院校和历史上的黑人学院和大学，以及年轻的研究人员（学生，博士后和年轻的教师）的参与。 为此，他们正在申请资金，通过为两名杰出的年轻女教师受邀演讲者和这些团体中被接受作口头或海报演讲的最多九名其他人提供旅费赠款，支持这些团体的参与。
