Abstract: Buildings account for over a third of anthropogenic GHG emissions and therefore need to play a pivotal role in any global decarbonization strategy. Buildings also protect their inhabitants during extreme weather events, a task that will only get harder as these events become increasingly frequent. Finally, the International Energy Agency predicts that a growing global population and rising standards of living may lead to a doubling of the global building stock by 2050. In short, the building sector faces the triple challenge of having to double its size, becoming more climate resilient and reducing its carbon footprint to zero in a quarter century. This presentation presents recent activities by the MIT Sustainable Design Lab to address these interrelated challenges. We have collaborated with over two dozen cities across the world on the development of technoeconomic carbon reduction pathways for their buildings, resulting in more informed policy measures, evidence-based carbon reduction targets and a better understanding of the scope required to meet ambitious calls for a net zero building stock. To prepare architecture students for the energy transition, we are working with over a dozen educators on a collection of hands-on concept and design exercises that empower students to develop realistic net zero building designs. I will end the presentation with a new approach that combines automated floorplan generation with environmental performance analyses.

Abstract: Fatigue failure is the process by which materials break during repetitive loading. In metals and alloys, fatigue cracks nucleate by an atomic-scale process called ‘persistent slip’. Transmission electron microscopy studies of conventional coarse grained metals show persistent slip bands as dislocation ladder structures with dimensions of several 100’s of nanometers to micrometers. However, in nanocrystalline alloys the grain size itself is less than 100 nanometers, thereby suppressing the formation of a persistent slip structure. As a result, these nanocrystalline alloys demonstrate substantial enhancement in fatigue resistance compared to conventional structural metals. The fatigue cracking process of nanocrystalline metals involves room-temperature grain growth. Only when the grains are grown mechanically to several 100’s of nanometers, does crack nucleation occur. This new mechanism has been confirmed by synchrotron x-ray diffraction and in-situ TEM experiments as well as molecular dynamics simulations. To mitigate this new failure mechanism, binary nanocrystalline alloys have been formulated with improved thermodynamic resistance to grain growth. In a first study on these alloys, we find that there are no signs of fatigue damage after 10 billion cycles at cyclic strain amplitudes up to 0.8% corresponding to stress amplitudes in excess of 1 GPa. This same alloy has also been shown to exhibit remarkable resistance to wear, with a wear rate superior to sapphire and comparable to diamond-like carbon.

Abstract: Immuno-engineering is an interdisciplinary field using approaches in immunology, bioengineering and material sciences to manipulate immunity for therapeutic purposes. Much has been focused on how immune cells can be engineered for treating diseases spanning diabetes and cancer to infectious diseases. In this talk, I will first share my lab’s effort to enhance diabetic wound healing through mechano-activation of fibroblasts. This will be followed by the inhibition of cancer-associated fibroblasts to treat pancreatic cancer. Finally, I will discuss how the incorporation of stromal cells to immune organoids can create a more authentic in vitro human immunity in a dish model for studying infectious diseases.

Abstract: Anaerobic Membrane Bioreactor (AnMBR) is a promising technology for sustainable domestic wastewater (DWW) treatment, enabling energy, water, and nutrients recovery at low biomass production rates. However, membrane fouling remains a major challenge, increasing costs and limiting long-term performance. While fouling is often attributed to biomass components like extracellular polymeric substances (EPS), the mechanisms linking biomass responses to operational conditions and fouling remain poorly understood. This study presents a mechanistic framework for AnMBR fouling, demonstrating how changes in organic loading rate (OLR) and coagulant addition influence sludge rheology, sludge dewaterability, EPS hydration and viscoelasticity, and ultimately affecting membrane fouling propensity. Parallel investigations at lab- and pilot-scale AnMBR systems treating real DWW provide a unique comparison between controlled and real-world conditions. Our integrated microscale-to-macroscale approach captures the complexity of biomass behavior. On the microscale, EPS hydration and viscoelasticity were analyzed using quartz crystal microbalance with dissipation (QCM-D) and localized surface plasmon resonance (LSPR). On the macroscale, dynamic rheometry, sludge volume index (SVI), and capillary suction time (CST) quantified biomass stability and dewaterability, while optical coherence tomography (OCT) and scanning electron microscopy (SEM) revealed biomass floc structure and fouling layer formation. Our findings provide an expansive explanation of how OLR and coagulant addition affect biomass destabilization and membrane fouling in AnMBR for DWW treatment, paving the way for improved fouling mitigation strategies and contributing to more stable and cost-effective AnMBR operations.

Abstract
The use of nanomaterials has become a rapidly growing approach for advanced water treatment technologies, but the continued emergence of highly oxidation-resistant micropollutants, such as per- and polyfluoroalkyl substances (PFAS), calls for transformative strategies that move beyond recent oxidation-based remediation practices. Alternative reduction-based approaches utilizing aqueous electrons (eaq−, Eo = −2.9 V)—one of the most reactive nucleophilic species—are emerging as a promising solution for efficient PFAS breakdown. Herein, we leverage nanoconfinement engineering to enable a new water treatment approach—plasmon-mediated advanced reduction processes (PARPs)—for efficient, chemical-free PFAS destruction at room temperature. We first present novel nanoreactor designs that engineer the ‘nanoconfinement effect’, i.e. unique aggregation-induced interparticle interactions that are inaccessible by typical unconfined, bulk-phase nanomaterials. We demonstrate that the precisely controlled nanoconfinement of plasmonic nanoparticles can generate highly reactive reducing species under UV irradiation, capable of breaking even the strong C–F bonds in PFAS. The nanoreactor we developed achieved 81.5% mineralization of perfluorooctanoic acid (PFOA) after 24 hours of UV irradiation in pure water at room temperature, compared to only 16.6% mineralization by UV photolysis. Further reaction monitoring under various conditions and multimodal NMR-guided investigation were conducted to elucidate PFAS degradation mechanisms and pathways. We further explored the potential of PARPs for the chemical-free remediation of nitrate, a prevalent oxyanion pollutant that is resistant to conventional oxidation-based treatments. Our findings highlight the transformative promise of nanoconfinement engineering to catalyze innovation in environmental nanotechnology and extend the frontier of advanced reduction processes for water treatment.
