Active Matter and Complex Media

活性物质是指自推进单元的集合体，例如，鸟类鱼类人类细菌无人机这些单位往往在没有任何外部指导的情况下，以各种结构自我组织。例如，鸟群和细菌群。活性物质的灵活性和多功能性（如八哥的杂音）激励着科学家和工程师开发具有类似特性的材料。这个暑期学校将向研究生和博士后研究人员介绍这个快速发展的领域的最新进展。这是一个支持美国青年科学家和学生参加将于2022年9月在Cargese（法国科西嘉岛）举行的“活性物质和复杂介质”暑期学校的注册和旅行相关费用的项目。大约15名美国参与者（研究生和博士后）预计将通过该资助获得支持，否则他们将无法参加。活性流体是那些可以自组装或以不同方式移动和包装的活性颗粒的存在，赋予流体不同的宏观性质。暑期学校的重点将放在非常活跃的研究领域，包括微生物游泳，运动胶体和活性颗粒在复杂和拥挤的环境（如多孔介质）中的集体行为。拟议的研讨会的目的是解决在建模的挑战，（合成、仿生和生命）物质，讨论克服这些挑战的方法，并教育和告知年轻科学家（主要是研究生），他们不仅将参加技术和基础知识讲座，还将参加由该领域国际知名专家举办的关于当前研究课题的研讨会，来自美国和世界各地。该会议具有很强的跨学科性质，涉及来自不同学科（物理学，工程学，应用数学，生物学）以及不同世代（专家高级科学家和学生）的研究人员。该奖项反映了NSF的法定使命，并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，被认为值得支持。

Active matter refers to collectives of self-propelled units, e.g., birds, fish, humans, bacteria, drones. The units tend to self-organize in various structures, without any external guidance. For example, birds flock and bacteria swarm. The agility and versatility of active matter (as seen in the starling murmurations) is inspiring scientists and engineers to develop materials with similar properties. This summer school will introduce graduate students and post-doctoral researchers to the latest advances in this rapidly evolving field. This is a project to support expenses related to the registration and travel of young scientists and students from the US to attend the summer school on " Active Matter and Complex Media" to be held in Cargese (Corsica Island, France) in September 2022. About 15 US participants (graduate students and post-docs) are expected to be supported through this grant, who would not otherwise be able to attend.Active fluids are those where the presence of active particles that can self-assemble, or can move and pack in different ways, give different macroscopic properties to the fluid. The focus of the summer school will be on areas that are very research active, including microorganism swimming, collective behavior of motile colloids and active particles in complex and crowded environment (such as porous media). The aims of the proposed workshop are to address challenges in the modeling of active (synthetic, biomimetic, and living) matter, to discuss approaches to overcome these challenges, and to educate and inform young scientists (mainly graduate students), who will be attending not only lectures on techniques and fundamentals, but also seminars on current research topics given by internationally known experts in the field, from the US and from around the world. The conference has a strong interdisciplinary character involving researchers from different disciplines (physics, engineering, applied mathematics, biology) as well as different generations (expert senior scientists and students).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.
