ACT/SGER: Biofuel Cells Operating on Ambient Organic Fuels for Distributed Sensor Networks

Scott A.卡拉布雷斯巴顿，哥伦比亚大学，支持创建高速率生物催化电极的生物燃料电池使用环境有机燃料在植物中。这项工作借鉴了正在进行的生物催化电极研究的结果，并将集中在（1）燃料成分和葡萄糖-果糖-蔗糖比例;（2）酶系统，如葡萄糖氧化酶，寡糖脱氢酶和转化酶-变旋酶-葡萄糖氧化酶;（3）通过氧化还原聚合物的电子介导，以促进在低电极电位下的高速率电子转移;（4）高度多孔的碳纤维作为优化的阳极支撑结构;和（5）对流效应以及它们将如何影响电极孔隙率和整体电池几何形状。 数学模型将用于指导阳极系统和完整生物燃料电池的实施。这项工作将导致从植物来源的生物催化能源发电的理解。除了技术影响外，该项目还包括与公立学校系统的外联以及研究和教育的整合。该奖项由NSF数学和物理科学理事会和情报界共同支持。打击恐怖主义方案支持基础研究和劳动力发展方面的新概念，这些概念有可能为国家安全作出贡献。

Scott A. Calabrese Barton, Columbia University, is supported to create high-rate biocatalytic electrodes for biofuel cells using ambient organic fuels in plants. The work draws on results from ongoing studies in biocatalytic electrodes and will focus on (1) fuel composition and glucose-fructose-sucrose proportions; (2) enzyme systems such as glucose oxidase, oligosaccharide dehydrogenase and invertase-mutarotase-glucose oxidase; (3) electron mediation through redox polymers to facilitate high-rate electron transfer at low electrode potential; (4) highly porous carbon fibers as optimized anode support structures; and (5) convection effects and how they will impact electrode porosity and overall cell geometry. Mathematical models will be used to direct implementation in the anode system and in the complete biofuel cell. This work will lead to enhanced understanding of biocatalytic energy generation from plant sources. In addition to the technological impact, this project also includes outreach to the public school systems and the integration of research and education. This award is supported jointly by the NSF Directorate for Mathematical and Physical Sciences and the Intelligence Community. The Approaches to Combat Terrorism Program supports new concepts in basic research and workforce development with the potential to contribute to national security.
