Bio-electrochemical systems (BES) couple redox chemical transformations to metabolic cycles in electrode-adhered biofilms (EABs) of electroactive bacteria. Applications include breakdown of organic waste molecules into small molecules, while producing energy or reducing energy required for electrosynthesis. Thus, BES are next-generation cleantech for a sustainable economy. This collaboration will replicate recent successes in combining theory and experiment in electrocatalysis1 for deeper insights and new applications involving BES. Microfluidic based BES hold the potential to streamline certain processes, enhance throughput, and improve figures of merit. The Greener group at U. Laval has become a leading developer of microfluidic BES and have used them for studies that have provided detailed understanding into fundamental aspects of EABs. This international collaboration seeks to generate new tools and knowledge aimed towards improving microfluidic BES. This requires help from Professor Hall's group at Penn State to adapt previously developed models based in rigorous electrochemistry theory to properly describe microfluidic bio-electrochemical flow cells. This will lead to new computer simulation methods that the Hall group will lead to merge computational fluidic dynamics simulations with mass-transport and electrochemical functionality that will accelerate development of new devices and to align our efforts with best practices in the field.The wider outcome of this collaboration will contribute to Canadian cleantech system development with the ultimate target being flow-based microbial fuel cells that can reduce costs and energy required for municipal waste-water treatment, which currently consume huge amounts of energy and produce proportional CO2 outputs. Eliminating these costs and emissions will be critical for achieving carbon neutrality in the coming decades and spin-off products will boost the Canadian economy. The collaboration features two experts in the field with complementary skills and is underpinned by a solid training plan with a heavy focus on equity, diversity and inclusion.

生物电化学系统（BES）将氧化还原化学转化耦合到电活性细菌的电极粘附生物膜（EABs）中的代谢循环。应用包括将有机废物分子分解成小分子，同时产生能量或减少电合成所需的能量。因此，BES是可持续经济的下一代清洁技术。这项合作将复制最近在电催化理论和实验相结合方面的成功，以获得更深入的见解和涉及BES的新应用。基于微流体的BES具有简化某些过程、提高通量和改善品质因数的潜力。美国的绿色组织。拉瓦尔已经成为微流体BES的领先开发者，并将其用于研究，提供了对EAB基本方面的详细了解。这项国际合作旨在产生新的工具和知识，旨在改善微流体BES。这需要宾夕法尼亚州立大学霍尔教授小组的帮助，以适应先前开发的基于严格电化学理论的模型，以正确描述微流体生物电化学流动池。这将导致新的计算机模拟方法，霍尔小组将导致合并计算流体动力学模拟与质量传输和电化学功能，这将加速新设备的开发，并使我们的努力与该领域的最佳实践保持一致。基于微生物燃料电池，可以降低城市污水处理所需的成本和能源，目前城市污水处理消耗大量能源，并产生成比例的二氧化碳输出。消除这些成本和排放对于在未来几十年实现碳中和至关重要，副产品将推动加拿大经济发展。该合作的特点是两名专家在该领域具有互补的技能，并以一个坚实的培训计划为基础，重点是公平，多样性和包容性。
