Abstract: Transarterial embolization (TAE) is a minimally invasive procedure that selectively delivers embolic agents into arteries to occlude diseased or injured vasculature for therapeutic purposes - including the treatment of hemorrhage, aneurysms, vascular malformations, and hypervascular tumors. Clinically available agents such as metallic coils, microspheres, and liquid embolics are widely used, but they face key limitations such as imprecise deployment, risk of migration, and catheter occlusion. In this talk, we will share our efforts to develop gel-based embolic agents as a novel alternative. These materials transition from a high-viscosity gel to a fluid under shear stress, allowing smooth catheter delivery, then rapidly re-solidify in situ to achieve stable vascular occlusion. We will highlight our integrated experimental and modeling approaches that validate transcatheter injectability, offering improved predictability and physician control. Finally, we will explore the multifunctional potential of these gel embolic agents - including therapeutic delivery, imaging compatibility, and photothermal therapy - as a platform for next-generation vascular devices.

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.
