The broader impact of this project is to understand the market driving force for a process-based technology to increase the efficacy of remediating chlorinated solvent-contaminated underground environment. Degradation of chlorinated solvents using earth-abundant minerals or metallic reagent is a topic of immense interest due to the prevalent presence of these solvent contaminants at hazardous waste sites and their recalcitrance to natural degradation. More effective and cost-efficient technologies to clean up these sites can generate societal benefits including decreasing the costs of remediation, accelerating the process of restoring land for re-development, and protecting human health and ecological well-being. This project will allow the project team to discover customer segments, identify key attributes of commercially successful remediation methods, and translate research outcomes to products that have commercial competitiveness and are amenable to large-scale implementation.This I-Corps project further develops fundamental understanding of reductive decomposition of chlorinated ethenes on reactive engineered surfaces. While the main research project seeks to explore the potential of adapting the surface properties of engineered materials to create highly reactive and selective surfaces for groundwater decontamination, this project aims to translate the research findings into prototype products or process-based technologies that have relevance to the practical needs of the remediation market and are commercially competitive against the existing remediation methods. This exploratory effort is aligned with the overall goal of advancing science to address the formidable challenges posed by groundwater contamination.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.

该项目的更广泛影响是了解以工艺为基础的技术的市场驱动力，以提高修复受氯化溶剂污染的地下环境的效率。利用地球上丰富的矿物或金属试剂降解氯化溶剂是一个非常有兴趣的话题，因为这些溶剂污染物普遍存在于危险废物场地，而且它们对自然降解的抵抗力。更有效和更具成本效益的清理这些地点的技术可以产生社会效益，包括降低补救成本，加快恢复土地重新开发的进程，以及保护人类健康和生态福祉。该项目将使项目团队能够发现客户群，确定商业上成功的补救方法的关键属性，并将研究成果转化为具有商业竞争力并适合大规模实施的产品。这个i-Corps项目进一步发展了对氯化乙烯在反应性工程表面上还原分解的基本理解。虽然主要研究项目试图探索调整工程材料的表面性质以创造用于地下水净化的高活性和选择性表面的潜力，但该项目旨在将研究成果转化为原型产品或基于工艺的技术，这些产品或技术与补救市场的实际需要相关，并在商业上与现有的补救方法相竞争。这一探索性的努力与推进科学以应对地下水污染带来的巨大挑战的总体目标是一致的。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。
