16th Annual Northeastern Granular Materials Workshop; New Haven, Connecticut; June 8, 2018

该奖项将支持将于2018年6月8日在康涅狄格州纽黑文市耶鲁大学举行的第16届东北颗粒材料研讨会（NEGMW）。NEGW系列的目标是将东北地区的颗粒研究小组聚集在一起，鼓励在涉及致密颗粒介质和其他无序颗粒材料力学的项目上进行合作和分享想法。研讨会的主题将涵盖广泛的软物质和力学研究，包括乳液，活性物质和玻璃。根据之前参加NEGMW的情况，至少有75名参与者，包括本科生、研究生、博士后和教职员工，将参加来自东北地区15所以上学院和大学的研讨会。NEGMW将包括四个45分钟的特邀演讲，六个15分钟的初级研究人员贡献的演讲和海报会议。四位受邀演讲者中有两位是女性教职员工，两位来自文理学院。NEGMW将解决有关颗粒介质和活性材料力学的几个重要问题。研讨会参与者将讨论驱动型耗散系统之间的关键物理差异（例如，驱动颗粒介质）和活性生物系统，如爬行细胞和游动细菌。此外，NEGMW演示文稿将探讨泡沫和乳液等可变形软材料中发生的流动缺陷和重排是否与颗粒介质和金属玻璃中的流动缺陷和重排相似。邀请和贡献的会谈，海报会议以及早餐，午餐和两个咖啡休息时间将为后续讨论提供间歇。研讨会结束时，将举行最后一次会议，与会者将讨论未来的研究方向，可能的多机构合作和资助机制，以及2019年6月下一届NEGMW的组织。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。

This award will support the 16th Annual Northeastern Granular Materials Workshop (NEGMW) to be held at Yale University in New Haven, Connecticut on June 8, 2018. The goal of the NEGW series is to bring together the granular research groups in the Northeast to encourage collaboration and sharing of ideas on projects involving the mechanics of dense granular media and other disordered particulate materials. The topics of the workshop will span a wide range of soft matter and mechanics research including emulsions, active matter, and glasses. Based on prior attendance at NEGMW, at least 75 participants including undergraduates, graduate students, postdocs, and faculty members will attend the workshop from more than 15 colleges and universities throughout the Northeast. The NEGMW will feature four invited 45-minute talks, six 15-minute contributed talks by junior researchers, and poster sessions. Two of the four invited speakers are female faculty members, and two are from liberal arts colleges. The NEGMW will address several important questions concerning the mechanics of granular media and active materials. Workshop participants will discuss the key physical differences between driven, dissipative systems (e.g., driven granular media) and active biological systems, such as crawling cells and swimming bacteria. In addition, NEGMW presentations will explore whether the flow defects and rearrangements that occur in deformable soft materials such as foams and emulsions are similar to those in granular media and metallic glasses. Invited and contributed talks, and poster sessions as well as breakfast, lunch, and two coffee breaks will provide interludes for follow-up discussions. At the close of the workshop, there will be a final session in which the participants will discuss future research directions, possible multi-institutional collaborations and funding mechanisms, and the organization for the next NEGMW in June 2019.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
