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与电活性细菌的电极粘附生物膜 (EAB) 中的代谢循环耦合起来。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。此次合作将复制电催化理论与实验相结合的最新成功经验，以获得更深入的见解和涉及 BES 的新应用。基于微流控的 BES 具有简化某些流程、提高吞吐量和改善品质因数的潜力。拉瓦尔大学的 Greener 小组已成为微流体 BES 的领先开发商，并将其用于研究，为 EAB 的基本方面提供了详细的了解。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。这将带来新的计算机模拟方法，霍尔小组将把计算流体动力学模拟与质量传输和电化学功能相结合，从而加速新设备的开发，并使我们的努力与该领域的最佳实践保持一致。此次合作将有助于加拿大清洁技术系统的开发，最终目标是基于流动的微生物燃料电池，该电池可以降低城市废水处理所需的成本和能源，目前城市废水处理消耗大量能源并产生一定比例的二氧化碳排放。消除这些成本和排放对于未来几十年实现碳中和至关重要，而衍生产品将提振加拿大经济。此次合作由两位技能互补的领域专家组成，并以坚实的培训计划为基础，重点关注公平、多样性和包容性。
