The Chemical Engineering Department is hosting a special graduate seminar on Materials and interfaces for the next generation batteries.

Abstract :

Humanity faces multiple converging crises such as pandemics, climate change, ecosystem degradation, and environmental pressures from rising global prosperity. We urgently need transformative solutions. At the same time, the past three decades have also witnessed sterling advances in genomics, synthetic biology, and computation, which have re-cast living systems as programmable platforms for innovation. Biology has now matured into a form of infrastructure - an enabling layer upon which solutions to health, the energy transition, material de-fossilization and the circular economy can be built.

Just as physical infrastructure underpinned the industrial age and digital infrastructure drives the current information age, biological infrastructure now offers the foundation for a sustainable one. Engineered biological systems can facilitate a more rapid response to emerging threats, enable sustainable resource recovery, as well as upcycle waste into high-value products. In this sense, biology is no longer confined to the laboratory; it is becoming the scaffolding of a new industrial paradigm where living and designed systems work in concert to sustain civilization.

Battery Workforce Challenge party

Please find attached the invitation with our new date, Thursday, Feb. 5^th. All are welcome but you must register to attend!

Even if you had previously registered, you must re-register, so we know how much delicious pizza we need to order for the new party date.

Hope to see you there!

The Chemical Engineering Department is hosting a special graduate lecture on Optimization and simulation-based approaches to manage logistics of trucks and ships in large supply chains.

Porous media form the backbone of electrochemical energy storage and conversion technologies, governing transport, reaction access, and overall efficiency in redox flow batteries, electrolyzers, and fuel cells. Despite their central role, most porous electrodes and transport layers have changed little over decades, relying on randomized architectures that constrain performance, durability, and cost. Dr. van der Heijden’s research group reimagines porous media as engineered components, structures that can be deliberately designed rather than inherited. By integrating pore‑scale modeling, operando imaging, computational optimization, and advanced manufacturing, the group uncovers fundamental structure–performance relationships and develops new architectures that reduce transport losses. This talk highlights how tailored porous microstructures can enable more efficient, robust, and scalable electrochemical devices.

Denitrification is a vital microbial process within the nitrogen cycle, where nitrate (NO3⁻) is reduced to nitrogen gas (N2), thereby alleviating nitrogen pollution in aquatic environments. Traditionally, organic carbon sources have been recognized as the primary electron donors for denitrification. However, recent research has underscored the significance of sulfur compounds as alternative electron donors, especially in settings where organic carbon is scarce. The current paradigm acknowledges the coexistence of heterotrophic and autotrophic denitrifiers in completing the denitrification pathway.
Facultative sulfur-driven denitrification represents an innovative biological process that integrates sulfide oxidation with denitrification, providing a dual solution for wastewater treatment. This process leverages specific heterotrophic bacteria capable of oxidizing sulfide while concurrently reducing nitrates, effectively eliminating both sulfide and nitrogen compounds from wastewater. The facultative nature of these bacteria enables them to adapt to fluctuating oxygen levels, thereby enhancing the process's flexibility and efficiency. This presentation will delve into recent advancements in facultative sulfur-driven denitrification, with a focus on its application in engineered systems such as wastewater treatment plants and bioreactors. By exploring the mechanisms and benefits of this process, we aim to highlight its potential for improving wastewater management and contributing to sustainable environmental practices.

Abstract: Dehumidification accounts for a substantial fraction of energy use and associated emissions in air‑conditioning systems, representing roughly 53% of energy‑related air conditioning emissions on a global average. Vapor-selective membranes, which preferentially transport water molecules while blocking the transport of other gases, have emerged as a promising alternative technology for the heating, ventilation, and air conditioning (HVAC) industry, even being ranked as a top alternative technology by the US Department of Energy. Over the past 20 years, the field has seen a significant amount of research interest in the development of high-performance membrane materials and synthesis procedures. However, translation of these materials advances into practical HVAC systems has largely relied on idealized thermodynamic system models, with a notable lack in experimental demonstration. As a result, a disconnect persists between membrane material development, component-level limitations, and realistic system and process design. This seminar presents our ongoing work aimed at bridging this gap by explicitly linking real membrane properties to component sizing, operating constraints, and system‑level efficiency. The broader goal of this research is to establish a holistic framework that integrates materials, components, and system design to clarify tradeoffs, define benchmark performance targets, and guide future research and development towards the broader adoption of high-efficiency, membrane-based HVAC technologies.
