Vapor-selective membranes\, which\npreferentially trans port water molecules while blocking the transport\nof other gases\, have e merged as a promising alternative technology for\nthe heating\, ventilatio n\, and air conditioning (HVAC) industry\, even\nbeing ranked as a top alt ernative technology by the US Department of\nEnergy. Over the past 20 year s\, the field has seen a significant\namount of research interest in the d evelopment of high-performance\nmembrane materials and synthesis procedure s. However\, translation of\nthese materials advances into practical HVAC systems has largely\nrelied on idealized thermodynamic system models\, wit h a notable lack\nin experimental demonstration. As a result\, a disconnec t persists\nbetween membrane material development\, component-level limita tions\,\nand realistic system and process design. This seminar presents ou r\nongoing work aimed at bridging this gap by explicitly linking real\nmem brane properties to component sizing\, operating constraints\, and\nsystem ‑level efficiency. The broader goal of this research is to\nestablish a holistic framework that integrates materials\, components\,\nand system de sign to clarify tradeoffs\, define benchmark performance\ntargets\, and gu ide future research and development towards the broader\nadoption of high- efficiency\, membrane-based HVAC technologies.

Davis Computer Research Centre Room 1302 200 Unive rsity Avenue West Waterloo ON N2L 3G1 Canada SUMMARY:Lecture Series CLASS:PUBLIC DESCRIPTION:Porous media form the backbone of electrochemical energy storag e and\nconversion technologies\, governing transport\, reaction access\, a nd\noverall efficiency in redox flow batteries\, electrolyzers\, and fuel\ ncells. Despite their central role\, most porous electrodes and\ntransport layers have changed little over decades\, relying on\nrandomized architec tures that constrain performance\, durability\, and\ncost. Dr. van der Hei jden’s research group reimagines porous media\nas engineered components\ , structures that can be deliberately designed\nrather than inherited. By integrating pore‑scale modeling\, operando\nimaging\, computational opti mization\, and advanced manufacturing\, the\ngroup uncovers fundamental st ructure–performance relationships and\ndevelops new architectures that r educe transport losses. This talk\nhighlights how tailored porous microstr uctures can enable more\nefficient\, robust\, and scalable electrochemical devices.

Traditionally\, \norganic carbon sources have been recognized as the primary electron\ndon ors for denitrification. However\, recent research has underscored\nthe si gnificance of sulfur compounds as alternative electron donors\,\nespeciall y in settings where organic carbon is scarce. The current\nparadigm acknow ledges the coexistence of heterotrophic and autotrophic\ndenitrifiers in c ompleting the denitrification pathway.\nFacultative sulfur-driven denitrif ication represents an innovative\nbiological process that integrates sulfi de oxidation with\ndenitrification\, providing a dual solution for wastewa ter treatment.\nThis process leverages specific heterotrophic bacteria cap able of\noxidizing sulfide while concurrently reducing nitrates\, effectiv ely\neliminating both sulfide and nitrogen compounds from wastewater. The\ nfacultative nature of these bacteria enables them to adapt to\nfluctuatin g oxygen levels\, thereby enhancing the process's flexibility\nand efficie ncy. This presentation will delve into recent advancements\nin facultative sulfur-driven denitrification\, with a focus on its\napplication in engin eered systems such as wastewater treatment plants\nand bioreactors. By exp loring the mechanisms and benefits of this\nprocess\, we aim to highlight its potential for improving wastewater\nmanagement and contributing to sus tainable environmental practices.
