项目摘要
Each of the two annual national meetings of the American Chemical Society includes several symposia in the Physical Chemistry Division. The topics of these symposia represent some of the most exciting areas of physical chemistry and chemical physics research. This year one of these featured symposia is Dynamics and Jamming in Complex Environments. The dynamics of particles in crowded and complex environments is intriguing from fundamental and applied points of view. Indeed, crowding determines particle dynamics in many physical, chemical, and biological systems, especially those far from equilibrium. Examples include liquid-to-solid transitions, dynamics in viscous liquids and particulate systems, and dynamics of biomolecules in living cells. Such physics is also of applied interest: indeed, at stake is our ability to design new materials and predict their static and dynamic properties. Inhomogeneity and lack of periodicity limits the utility of conventional bulk experiments to detail molecular motions in these systems. Moreover, such experiments, as well as direct computational studies, are complicated by the enormous range of dynamics displayed by these systems. Emerging experimental, simulation-based, and theoretical approaches to investigating these complex systems can address questions that have evaded clear answers about the nature of these slow relaxations, broadly termed glassy dynamics, and the glass transition despite decades of effort. The co-organizers of this symposium request funds to help defray registration and travel costs for speakers and poster presenters at this meeting. In particular, these funds will be used primarily for graduate student and postdoctoral presenters. The symposium will bring together diverse scientists: they are diverse in their areas of research, in their chosen experimental and/or theoretical tools, and in their nationality, age, and gender. In particular, members of underrepresented groups have been recruited to participate via presentation of both invited and contributing talks - advertisements featuring such speakers then, in turn, encourage additional participation from members of these groups as attendees and poster presenters at the symposium. The set of invited speakers represent a much broader community than those typically present at conferences on glasses, which tend to focus on either molecular glasses or soft matter or granular systems and do not generally include both experimentalists and theorists. The support requested will broaden the community participating in this symposium and in turn encourage new synergies between researchers in diverse communities. The chief goals of this symposium are (1) exploring the commonalities in the various systems in which crowding is an important determinant of dynamics and (2) continuing to develop a common language with which to discuss glassy behavior.
美国化学会的两次全国年度会议均包括物理化学分部的多次研讨会。这些研讨会的主题代表了物理化学和化学物理研究中一些最令人兴奋的领域。今年的特色研讨会之一是复杂环境中的动力学和干扰。从基础和应用的角度来看,拥挤和复杂环境中的粒子动力学非常有趣。事实上,拥挤决定了许多物理、化学和生物系统中的粒子动力学,尤其是那些远离平衡的系统。例子包括液体到固体的转变、粘性液体和颗粒系统的动力学以及活细胞中生物分子的动力学。这种物理学也具有应用价值:事实上,我们设计新材料并预测其静态和动态特性的能力至关重要。不均匀性和缺乏周期性限制了传统批量实验在这些系统中详细描述分子运动的实用性。此外,此类实验以及直接计算研究因这些系统显示的巨大动态范围而变得复杂。研究这些复杂系统的新兴实验、基于模拟和理论的方法可以解决一些问题,尽管经过数十年的努力,这些问题仍然无法明确回答这些缓慢弛豫、广义上称为玻璃态动力学和玻璃化转变的性质。本次研讨会的联合组织者请求资金来帮助支付本次会议演讲者和海报展示者的注册和差旅费用。特别是,这些资金将主要用于研究生和博士后演讲者。研讨会将汇集不同的科学家:他们的研究领域、选择的实验和/或理论工具以及国籍、年龄和性别各不相同。特别是,代表性不足的群体的成员通过受邀演讲和贡献演讲的方式被招募参加——以此类演讲者为主角的广告反过来又鼓励这些群体的成员作为与会者和海报展示者更多地参与研讨会。受邀演讲者代表的群体比通常出席眼镜会议的群体要广泛得多,眼镜会议往往关注分子玻璃、软物质或颗粒系统,通常不包括实验学家和理论家。所请求的支持将扩大参与本次研讨会的社区,进而鼓励不同社区的研究人员之间产生新的协同作用。本次研讨会的主要目标是(1)探索各种系统中的共性,其中拥挤是动态的重要决定因素;(2)继续开发一种共同语言来讨论呆滞行为。
