EAGER: IMPRESS-U: Developing new approaches and structural materials to rebuild damaged Ukrainian infrastructure with environmental sustainability considerations

探索性研究国际多边伙伴关系乌克兰弹性教育和科学系统(IMPRESS-U)项目的重点是使用新一代传统和3D打印技术建造难民收容所的创新方法，该技术利用与美国、波兰和乌克兰相关的废物组合。这项研究将通过使用新颖、廉价和节能的解决方案来应对构建弹性和可持续基础设施方面的挑战。这将与乌克兰尤其相关，在乌克兰，重建受损的经济将带来前所未有的工程和金融挑战。该项目还将采用环境可持续性框架来指导3D打印方法的材料选择。提高这一国际伙伴关系的效率和弹性的创造性方法将包括将乌克兰和波兰的土木工程学者和学生整合到州长岛的石溪气候解决方案中心。通过一个基于在线协作国际学习(COIL)的虚拟国际交流计划，将通过美国、波兰和乌克兰的大学课程，重点是结构工程和先进材料，实现高效的概念，以培养一支参与国际研究的队伍。帮助难民的实际成果将以乌克兰与当地一家建筑公司的伙伴关系为基础，该公司在基辅和基辅地区使用住宅3D混凝土打印技术建造房屋。总体而言，虚拟课程、教学和交流活动的新方法、联合研究和创新项目的组合将重塑乌克兰的研究、教育和创新生态系统。该项目将通过建立废物成分/结构(化学、物理和其他)与含有回收材料的混凝土的机械/耐久性能之间的新关联，来解决将废物纳入3D打印的众多研究挑战。从不同类型的废物中设计出新颖的分层结构，将可变(纳米、微观、宏观)颗粒同时混合到相同的混凝土样品中，可能会提供前所未有的机械、热学、耐久性，甚至自我修复性能。该计划的一个重要角度是对基于废物的集合体的制备进行生命周期分析(LCA)，作为其大小和化学成分的函数。这个ENGER：IMPRESS-U项目将由NSF、美国国家科学院、全球海军研究办公室(DoD)和波兰国家科学中心联合支持。这项研究将联合美国石溪纽约州立大学、乌克兰基辅国立建筑大学和波兰比德戈兹科技大学共同开展。这个项目的美国部分是由NSF国际科学与工程办公室和ENG/CBET项目共同资助的。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This EAger-concept Grant for Exploratory Research (EAGER) International Multilateral Partnerships for Resilient Education and Science System in Ukraine (IMPRESS-U) project focuses on innovative methods of construction of refugee shelters using a new generation of traditional and 3D printing technology that utilizes a combination of waste materials relevant to the US, Poland, and Ukraine. This research will address challenges in building resilient and sustainable infrastructure by using novel, inexpensive, and energy efficient solutions. It will be especially relevant to Ukraine, where rebuilding its damaged economy will pose unprecedented engineering and financial challenges. The project will also adopt an environmental sustainability framework to guide materials selection for 3D printing approaches. Creative ways for enhancing efficiency and resiliency of this international partnership will include integration of Ukrainian and Polish civil engineering academics and students into Stony Brook Climate Solutions Center on Governors Island. Efficient concepts to prepare an internationally engaged research workforce will be achieved through a virtual international exchange program based on Collaborative Online International Learning (COIL) that will be delivered through American, Polish, and Ukrainian university courses focused on structural engineering and advanced materials. Practical outcome of helping refugees will be based on Ukrainian partnership with a local construction company that builds houses in Kyiv and Kyiv region using 3D concrete printing technologies for residential buildings. Overall, a combination of virtual courses, new approaches to teaching and exchange activities, joint research and innovation projects will reshape the research, education, and innovation ecosystem in Ukraine. The project will address a multitude of research challenges to waste incorporation into 3D printing by developing new correlations between waste composition/structure (chemical, physical, and others), and resulting mechanical/durability properties of concrete containing recycled materials. Designing novel hierarchical structures derived from different types of waste with variable (nano, micro, macro) particles that are simultaneously mixed into the same concrete samples will potentially deliver unprecedented mechanical, thermal, durability and even self-healing properties. An important angle of the program is in conducting Life Cycle Analysis (LCA) for the waste-based aggregates’ preparation as a function of their size and chemical composition.This EAGER: IMPRESS-U project will be jointly supported by NSF, US National Academy of Sciences, Office of Naval Research Global (DoD), and National Science Centre of Poland. The research will be conducted in collaborative partnership that unites the SUNY at Stony Brook in the US, Kyiv National University of Construction and Architecture in Ukraine, and Bydgoszcz University of Science and Technology in Poland. The US portion of this EAGER: IMPRESS-U project is co-funded by NSF Office of International Science and Engineering and ENG/CBET program.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.
