OIA - 2137561 NSF Convergence Accelerator Track E: Next generation biomaterials with engineered biodegradability to enable networked swarm sensing in the oceanAbstractThis research focuses on marine debris management to facilitate a more sustainable engagement with the ocean. It embodies a Convergence Research approach by bringing together a team of microbiologists, materials scientists, engineers, and oceanographers from four academic institutions collaborating with industry partners from the oceanographic instrumentation sector and government experts. Today, plastics are a $4-trillion industry; but less than 1% are bioplastics. This project will pioneer a novel approach to designing materials for the marine environment by explicitly considering the metabolism of microbes in the environment in which they are expected to biodegrade. Expendable, networked, free-drifting instruments are revolutionizing ocean observation, but these growing fleets of sensors present an environmental challenge and require a necessary shift in how society thinks about the materials used in their construction. At present, most “biodegradable” plastics have limited biodegradation in cold, dark oceanic conditions and were designed and tested only in industrial composting facilities. This project will develop both sustainable materials and testing standards that accurately reflect ocean conditions. The successful development of materials designed to rapidly degrade in seawater is expected to transform multiple marine sectors, such as fisheries, and permeate wider industry applications where marine pollution by plastics is of major concern.The research team will pioneer the embedding of live PHA-degrading marine bacteria directly into plastic materials by developing strategies for extending the viability of living cells in printed materials. The field-deployable respiration chamber developed as part of this project is expected to set a new industry standard for testing materials used in the marine environment. Materials that facilitate rapid degradation of marine instrumentation under realistic environmental conditions would transform society’s ability to deploy swarm sensors at scale. Solving this problem requires the convergence of intellectually distinct fields and approaches, as well as the involvement of stakeholders that manage marine debris and end-users. The research team will innovate, test, and integrate biomaterials designed to rapidly degrade at end-of-life in oceanic conditions. The project will develop a suite of novel plastic materials purpose-built for the marine environment by 3D printing living bacteria into the biopolymer polyhydroxyalkanoate (PHA), optimized with additives to supplement microbial metabolism. Second, it will modify existing marine instrumentation to produce a chamber for directly measuring the respiration of plastic materials in deep ocean environments. Finally, the research team will work with end users to prototype products designed to be deployed in the marine environment. The overarching objective of the project is to integrate sustainable materials into oceanographic instrument applications.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.

OIA -2137561 NSF收敛加速器轨道E：具有工程生物降解性的下一代生物材料，以使OceanAbstracties Tihthis Research的网络群体感测的侧重于海上调试管理，以支持与海洋更具可持续性的接触。它通过将来自四个学术机构的微生物学家，材料科学家，工程师和海洋学家组成的团队与来自海洋学仪器部门和政府专家的行业合作伙伴合作的团队结合在一起，体现了一种融合研究方法。如今，塑料是一个耗资4亿美元的行业；但是不到1％是生物塑料。该项目将通过明确考虑在环境中明确考虑其生物降解的环境中的代谢，从而开创一种为海洋环境设计材料的新型方法。消耗性，网络，自由捕捞的工具正在彻底改变海洋观察，但是这些不断增长的传感器带来了环境挑战，并需要对社会对建筑中使用的材料的思考方式进行必要的转变。目前，大多数“可生物降解”塑料在寒冷，黑暗的海洋条件下的生物降解有限，并且仅在工业组成设施中进行设计和测试。该项目将开发可持续材料和测试标准，以准确反映海洋条件。预计旨在快速降级的材料的成功开发将改变多个海洋领域，例如渔业，并渗透到广泛的行业应用中，在这些领域中，塑料污染的海洋污染是主要的关注点。研究团队将开拓实时PHA剥夺海洋细菌的塑料材料，通过开发塑料材料，通过开发策略，以扩展现有的生命材料的塑料材料。作为该项目的一部分开发的可田间呼吸室有望为海洋环境中使用的测试材料设定新的行业标准。在现实的环境条件下促进海洋仪器快速退化的材料将改变社会在大规模部署群体传感器的能力。解决此问题需要智能不同领域和方法的融合，以及管理海洋调试和最终用户的利益相关者的参与。研究小组将无效，测试和集成的生物材料，旨在在海洋条件下快速降级。该项目将通过3D印刷活细菌为生物聚合物多羟基烷酸盐（PHA）开发一套针对海洋环境的新型塑料材料，并用添加剂优化，以补充微生物代谢。其次，它将修改现有的海洋仪器，以生产一个腔室，以直接测量深海环境中塑料材料的呼吸。最后，研究团队将与最终用户合作，以​​制定旨在在海洋环境中部署的原型产品。该项目的总体目的是将可持续材料整合到海洋学工具应用中。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估，被视为珍贵的支持。
