Collaborative Research: Engineering Design of Oxygen Rich Surfaces for Bioelectrodes

这项资助的研究目的是阐明作为生物电极和生物燃料电池材料的金属氧化物支撑的多孔膜中氧的传输、渗透和释放的基本过程。该研究项目将在一个多孔的三维网络中研究金属掺杂和混合金属氧化物的催化、氧化还原以及储氧和放氧性能，该网络将用于制造能够在生理和环境温度条件下运行的“富氧”表面。将使用一套光谱、电化学和扫描电化学显微镜方法来帮助理解多孔层中酶/掺杂金属氧化物界面上的氧传输机制，并建立组成、形貌和相应生物电催化性能之间的关联。这项研究将改善表面的氧气利用率和渗透性，提高生物电极的整体性能。如果成功，这种跨学科的合作努力将使新一代材料和表面的开发能够在氧气受限的条件下使用。这项研究在生物电化学和生物燃料电池领域引入了一项独特的技术，以促进氧气的流动并提供储存/释放能力。这项研究项目将在学生培训的各个方面促进批判性思维技能的创新和发展，以发展使未来能够发现的知识基础。研究生和本科生，特别是少数民族和女性，将参与这项研究。K12的学生和教师将通过两个合作机构的既定机制接触到这项研究。

The research objective of this grant is to elucidate the fundamental processes of the oxygen transport, permeability, and release in porous, metal oxide supported biofunctionalized membranes, as materials for bioelectrodes and biofuel cells. The research project will study the catalytic, redox, and oxygen storage and release properties of metal doped and mixed metal oxides within a porous tridimensional network that will be used to fabricate "oxygen-rich" surfaces that are able to operate under physiological and ambient temperature conditions. A suite of spectroscopic, electrochemical, and scanning electrochemical microscopy methods will be used to facilitate understanding of the oxygen transport mechanism at the enzyme/doped metal oxide interface in the porous layer and to establish correlations between composition, morphology, and corresponding bioelectrocatalytic performance. This research will improve oxygen availability and permeability at surfaces, enhancing the overall performance of bioelectrodes.If successful, this interdisciplinary collaborative effort will enable development of a new generation of materials and surfaces that can be used in oxygen restrictive conditions. This research introduces a unique technology in the field of bioelectrochemistry and biofuel cells for facilitating oxygen mobility and providing storage/release capabilities. This research project will promote innovation and development of critical thinking skills in all aspects of student training to develop a foundation of knowledge that will enable future discoveries. Graduate and undergraduate students, especially minorities and women, will participate in this research. K12 students and teachers will be exposed to this research through established mechanisms at the two collaborating institutions.
