项目摘要
Globally, there is untapped power equivalent to approximately 2,000 nuclear power plants that could be generated at coastal estuaries from the mixing of fresh and salt water. To date, however, there have been no economical ways to extract this clean 'blue' energy from natural salt gradients. This is largely due to the poor efficiencies and high cost of existing membrane technologies. This Grant Opportunity for Academic Research with Industry (GOALI) collaborative award supports fundamental research on a new approach to manufacturing membranes for efficient energy conversion from salinity gradients, using boron-nitride nanotubes (BNNT) as uniquely smooth, highly charged nanoscale pores. The new nanomanufacturing process enables fabrication of energy-harvesting BNNT membranes with power densities ten to 100 times greater than existing membranes, in an efficient and cost-effective manner that can be scaled up to high production rates and large-scale membranes many meter-square in size. The knowledge base and nanomanufacturing methods that are developed enable renewable energy generation from an under-utilized and non-intermittent power source, and are also generally applicable to the design and manufacture of the specialized membranes that are critical to many industrial processes. This GOALI collaborative research, between an industrial partner, Chasm Technologies, and Chemical and Mechanical Engineers at two universities, helps students develop multidisciplinary skills and gain industry-relevant experience. Concerted outreach efforts to spark interest in Science, Technology, Engineering and Mathematics among women and under-represented minority students enhances diversity and help fill US workforce needs. The GOALI collaborative research project devises the first scalable, roll-to-roll-compatible method for producing vertically aligned boron-nitride nanotube (BNNT) membranes. This is achieved with a solution-based approach that deposits and aligns oligomer-dispersed BNNTs under the influence of an external electric field, and locks the nanostructure in position by in situ polymerization. The project develops a fundamental understanding and methods for solution-based fabrication at lab scales, targeting 1-10 cm2 membranes with pore densities of 108 - 1010 BNNTs/cm2. The availability of such membranes provides answers to basic questions regarding ion and liquid transport in highly charged nanoscale pores, the implications for molecular separations and electrokinetic energy conversion. The academic collaborators are planning to work with industry partner Chasm Technologies to develop the subsystems and processing steps (e.g., coating, electrokinetic alignment, curing, and post processing) to enable roll-to-roll manufacturing of large-area BNNT membranes. Together, the team studies scalability of the manufacturing process, membrane yield and performance as the size is increased to 100 cm2 and beyond.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.
在全球范围内,有相当于大约2 000个核电厂的未开发电力,可以在沿海河口通过淡水和盐水的混合产生。然而,迄今为止,还没有经济的方法从天然盐梯度中提取这种清洁的“蓝色”能源。这在很大程度上是由于现有膜技术的效率低和成本高。这个学术研究与工业(GOALI)合作奖的资助机会支持基础研究的一种新的方法来制造膜,从盐度梯度有效的能量转换,使用氮化硼纳米管(BNNT)作为独特的光滑,高度带电的纳米级孔。新的纳米制造工艺能够制造能量收集BNNT膜,其功率密度是现有膜的10到100倍,以高效和具有成本效益的方式,可以扩大到高生产率和许多平方米大小的大规模膜。 开发的知识库和纳米制造方法能够从未充分利用和非间歇性电源中产生可再生能源,并且通常也适用于对许多工业过程至关重要的专用膜的设计和制造。 这项GOALI合作研究是工业合作伙伴Chasm Technologies与两所大学的化学和机械工程师之间的合作,帮助学生发展多学科技能并获得行业相关经验。 协调一致的外联工作,以激发妇女和代表性不足的少数民族学生对科学,技术,工程和数学的兴趣,增强了多样性,并有助于满足美国的劳动力需求。GOALI合作研究项目设计了第一种可扩展的卷对卷兼容方法,用于生产垂直排列的氮化硼纳米管(BNNT)膜。这是通过基于溶液的方法实现的,该方法在外部电场的影响下沉积和排列低聚物分散的BNNT,并通过原位聚合将纳米结构锁定在适当位置。该项目开发了实验室规模的基于溶液的制造的基本理解和方法,目标是孔密度为108 - 1010 BNNT/cm 2的1-10 cm 2膜。这种膜的可用性提供了答案的基本问题,离子和液体在高度带电的纳米级孔的运输,分子分离和电动能量转换的影响。学术合作者计划与行业合作伙伴Chasm Technologies合作开发子系统和处理步骤(例如,涂布、电动对齐、固化和后处理),以实现大面积BNNT膜的卷对卷制造。该团队共同研究了制造过程的可扩展性、膜产量和性能,因为尺寸增加到100 cm 2及以上。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。
