TECHNICAL SUMMARY: This CAREER project aims to acquire fundamental and comprehensive understanding of the relationships among processing, microstructure and properties of magnesium-based nanoporous materials. The specific technical objectives of the research are to synthesize magnesium-based nanoporous materials, characterize their microstructural features using the state-of-the-art tools, experimentally investigate their properties and mechanical behavior and evaluate these behaviors in the light of current theoretical understanding. NON-TECHNICAL SUMMARY: The success of this research will allow full advantage to be taken of nanoporous magnesium for a variety of applications that utilize combinations of mechanical properties, ultralight weight, excellent energy absorption capability, and multifunctionality that accompany the introduction of nanopores into non-porous metals. The research will also advance the underlying understanding of the processing-structure-property relationships in other nanoporous metallic materials. This project will integrate research and education/outreach activities to train undergraduate and graduate students for the workforce, and stimulate the interest and participation of high school students and underrepresented student groups (Hispanic and Women) in science and engineering. The results will be disseminated to other researchers and the general public through a variety of channels such as international journals, technical conferences and the internet. These activities are expected to increase the general public awareness of advanced nanostructured metallic materials and their scientific importance, and to enhance the broader public interest in science, engineering, and the pursuit of technology-oriented careers.

技术概要：本项目旨在对镁基纳米多孔材料的加工、微观结构和性能之间的关系获得基本和全面的理解。该研究的具体技术目标是合成镁基纳米多孔材料，使用最先进的工具表征其微观结构特征，实验研究其性能和机械行为，并根据当前的理论理解评估这些行为。非技术性总结：这项研究的成功将允许充分利用纳米多孔镁用于各种应用，这些应用利用机械性能，超轻重量，优异的能量吸收能力和多功能性的组合，这些功能性伴随着将纳米孔引入非多孔金属。该研究也将推进对其他纳米多孔金属材料的加工-结构-性能关系的基本理解。该项目将整合研究和教育/推广活动，为劳动力培养本科生和研究生，并激发高中生和代表性不足的学生群体（西班牙裔和女性）对科学和工程的兴趣和参与。研究结果将通过国际期刊、技术会议和互联网等多种渠道向其他研究人员和公众传播。预计这些活动将提高公众对先进纳米结构金属材料及其科学重要性的认识，并提高公众对科学，工程和追求技术导向职业的兴趣。
