Abstract: Global decarbonization of the energy sector necessitates development of storage technologies to mediate the inherent intermittency of renewable resources. Electrochemical systems are well-positioned to support this transition with redox flow batteries (RFBs) emerging as a promising grid-scale platform, as their unique architecture offers decoupled energy / power scaling, simplified manufacturing, and long service life. Despite these favorable characteristics, current embodiments remain prohibitively expensive for broad adoption, motivating the development of new electrolyte formulations (e.g., redox molecules, supporting salts, solvents) and reactor materials (e.g., electrodes, membranes) to meet performance and cost targets for emerging applications. While many next-generation materials offer performance improvements, they must carefully balance complex tradeoffs between power / energy density, cycling stability, energy efficiency, and capital costs. This multifaceted parameter space frustrates the articulation of unambiguous design criteria, as the relationships between constituent material properties and cell performance metrics are not yet well-understood. To this end, my research establishes rational design strategies for RFBs to enable robust, cost-competitive, and durable grid-scale energy storage.
In this talk, I will first introduce a modeling framework for describing cell cycling behavior in RFBs, building on thermodynamic, kinetic, and transport descriptions for electrochemical processes. Using this generalized set of constitutive equations, I will discuss analytical solutions for the coupled mass balances, enabling facile simulation of charge / discharge behavior and device performance metrics. I will then describe the development of new experimental methodologies that facilitate characterization of constituent materials under conditions that more closely resemble those observed in practical embodiments. Broadly, the methods developed in this work have the potential to advance foundational understanding in RFB design and operation, leading to more rigorous selection criteria for candidate materials.

Abstract: Accelerating the discovery of new molecules and materials, as well as green and sustainable ways to synthesize and manufacture them, will have a profound impact on the global challenges in energy, sustainability, and healthcare. The current human-dependent paradigm of experimental research in chemical and materials sciences fails to identify technological solutions for worldwide challenges in a short timeframe. This limitation necessitates the development and implementation of new strategies to accelerate the pace of discovery. Recent advances in reaction miniaturization, automated experimentation, and data science provide an exciting opportunity to reshape the discovery and manufacturing of new molecules and materials related to energy transition and sustainability. In this talk, I will present a ‘self-driving fluidic lab (SDFL)’ for autonomous discovery and manufacturing of emerging advanced functional materials and molecules, with multi-step chemistries, through integration of flow chemistry, online characterization, and machine learning (ML). I will discuss how modularization of different chemical synthesis and processing stages in tandem with a constantly evolving ML modeling and decision-making under uncertainty can enable a resource-efficient navigation through high dimensional experimental design spaces (>1020 possible experimental conditions). Example applications of SDFL for the autonomous synthesis of clean energy nanomaterials will be presented to illustrate the potential of autonomous robotic experimentation in reducing synthetic route discovery timeframe from >10 years to a few months. Finally, I will present the unique reconfigurability aspect of flow chemistry to close the scale gap in chemical and materials research through facile switching from the reaction exploration/exploitation to smart manufacturing mode.

Jennifer Wilcox, US Department of Energy
Host: Prof. Jay Werber
President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the U.S. by 2050. The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the Nation’s electricity sector by 2035. Investment in technology research, design, development, and deployment (RDD&D) will be required to achieve the president’s objectives, including investments in both carbon capture at point sources in addition to carbon dioxide removal approaches that target the accumulated pool of carbon in the atmosphere. Both will be required to achieve net-zero carbon emissions in time and they will require increased deployment in order to move down the cost curve. These efforts combined with effective policy will make these approaches economically viable.
These approaches are critical and they must be deployed in parallel. Deployment of these technologies at the scale required will necessitate the use of resources including land, water, and in some cases, low-carbon energy, while ensuring the secure and reliable storage of carbon dioxide (CO2) on a timescale that impacts climate. Therefore, CCS and CDR deployment must be implemented strategically in terms of regional goals and requirements.
The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors – through investments in technology solutions including CCS, direct air capture, and the deployment of carbon capture technologies to produce low-carbon products and fuel, including hydrogen.

Abstract: Amongst the greatest challenges faced by modern society are the transition to sustainable technologies and the always-pressing need to develop healthcare solutions. Many of the proposed innovations to address these challenges require the ability to design materials with unprecedented structural and compositional control. Automation is emerging as a solution to provide controlled synthesis, processing, and assembly of polymer materials; combined with data science, these two tools are well-poised to accelerate the discovery and development of advanced materials. This talk will first discuss engineering strategies towards controlling polymer molecular weight, composition, and topology with a digital level of precision. Precision synthesis is achieved with an automated flow reactor and is demonstrated by the complete control over polymer molecular weight distribution shape, as well as the synthesis of shape-defined bottlebrush polymers. This work pushes the limits of molecular design and assembly, with applications as a nanostructured material for electronics, structural color, filtration, water purification, and energy storage. The second half of the talk will focus on the development of high throughput automation for polymer synthesis and the role of data science for polymer material discovery.

Host: Prof. Ramin Farnood
These are very exciting times in fundamental and applied environmental microbiology owing to significant advances in analytical tools and techniques to interrogate complex biological systems. These tools include affordable large-scale sequencing, quantitative DNA and RNA extraction and amplification tools, powerful microscopy, and proteomic analyses applicable to complex mixtures and small sample sizes. These techniques are enabling novel approaches and improved modelling to uncover fundamental metabolism, regulation, genetics, and interspecies metabolite transfer in complex microbial ecosystems. Specific applications related to my own research include biomethane production, wastewater treatment and surveillance, and soil and groundwater bioremediation. These processes rely on complex microbial communities that have defied traditional reductionist microbiological approaches. In this talk, I will discuss how combinations of modern genome-enabled tools have been used to monitor microbial communities and to decipher beneficial interactions in complex microbial consortia, whose activity is greater than the sum of their individual parts.

“What if waste wasn’t?” is a question that requires careful consideration. Although it appears attractive to convert waste into valuable products, the technical and economic feasibility of any conversion process must be carefully analyzed. Gasification is a process in which solids and liquids are converted to gases but unlike combustion, in which the products are carbon dioxide and water, the products are a mixture of mainly hydrogen and carbon monoxide. This mixture can be used to run an engine to produce power or chemically converted to make other fuels in a Fischer-Tropsch synthesis process. Contaminants in the waste may impact the gasification process by deactivating catalysts, which are substances that increase the rates of reaction, and/or forming species that damage the process equipment (e.g., through corrosion). The additional units required to remove the contaminants, either up- or downstream may make the process economically unfavourable, as may the cost to transport the feed and products. This presentation will discuss the various waste streams available in Canada, the potential technical challenges of using these streams, and the techno-economic analysis of a few scenarios.

Host: Prof. Frank Gu
Functionalization of materials aims at predetermining their behavior and fate in application relevant system environments. Various chemistry-based approaches are established such as covalent coupling of bioactive molecules to foster their interaction with cells or incorporation of easily cleavable bonds to gain degradability. The shape-memory effect is an example for a function, which can be implemented in polymers by physical manipulation. As this memory can be recalled, deleted or changed, this process is named programming. Morphologies of porous materials and geometrical arrangements in multimaterial systems can serve as design criteria for structural functions or dynamic behaviors as required for actuators. The targeted design of multifunctional polymeric materials will be illustrated for medical applications and sustainable products. A perspective on the potential of digital methods to predict the functional behavior of polymers, to support the design of devices and enable their fabrication will be given.

Marianthi Ierapetritou, University of Delaware
Host: Prof. Krishna Mahadevan
The growing concerns over global warming and environmental issues motivate the research on replacing oil-based feedstocks with biomass raw material for chemical and fuel production. This however comes with a number of challenges as the new technologies have to compete with the fossil based mature processes to ensure economic viability and market competitiveness. Moreover, life cycle analysis is not always in favor of the “green” solutions depending on the pathway explored.
Optimization of the biomass feed splitting among alternative pathways considering their economic and environmental impacts can be thus explored to discover the best available routes and determine the optimal mix of the value-added products. Hence, the integrated biorefinery is proposed to combine different conversion technologies and fully utilize all biomass components using the superstructure optimization framework. In addition to selecting the most economical and sustainable feedstock-technology-product combinations, the integrated biorefinery strategy can also include process flexibility to adjust its production in the volatile chemical market.
Acknowledging the increasing market competition, environmental concerns, and uncertainty in price and transportation times, there is a growing interest in achieving modularization, design standardization, and process intensification for biomass processing. The integration of modular designs within the existing supply chain could be challenging. Supply chain networks have become more prominent, complex, and difficult to manage, especially considering the multitude of risks and uncertainty that may manifest. In this talk, I will also touch upon the work in our group towards developing a supply chain model that aids decision-making addressing the complexities of a modular infrastructure and provide some ideas to deal with disruptions by considering both proactive and reactive strategies.

From urban centers to remote corners of Earth, the depths of the oceans to space, humanity has always sought to transcend barriers, overcome challenges, and create opportunities that improve life on our part of the universe. One such challenge is securing good nutrition for the global population, many of whom have just a few dollars a day to secure a nutritious meal. Nutrition is a ‘Grand Challenge’ affecting the world’s most vulnerable populations and needs a multidisciplinary approach and a ‘new breed’ of Engineers that can transcend across multiple disciplines and apply their analytical and solution-oriented thinking. While Engineers have and continue to develop ingenious solutions and technologies to make food healthier and safer, global rates of malnutrition remain unacceptably high in many countries resulting in productivity losses, morbidity and mortality. The aim of my lecture is to share some of my experiences and perspectives that have enabled me to make a positive impact on nutrition with the hope that this may inspire engineering researchers and students to solve the world’s most stubborn problems.
