Bipolar membranes (BPMs) enable control of ion concentrations and fluxes in electrochemical cells suitable for a wide range applications. Here we present the multi-scale physics BPMs an engineering context articulate design principles to drive development advanced BPMs. The chemistry, structure, are illustrated related thermodynamics, transport phenomena, chemical kinetics that dictate species selectivity. These interactions give rise emergent structure–property–performance relationships...
A necessary transformation for a sustainable economy is the transition from fossil-derived plastics to polymers derived biomass and waste resources. While renewable feedstocks can enhance material performance through unique chemical moieties, probing vast design space by experiment alone not practically feasible. Here, we develop machine-learning-based tool, PolyID, reduce of enable efficient discovery performance-advantaged, biobased polymers. PolyID multioutput, graph neural network...
Anion exchange membrane water electrolysis (AEMWE) is a promising technology to produce hydrogen from low-cost, renewable power sources. Recently, the efficiency and durability of AEMWE have improved significantly due advances in anion polymers catalysts. To achieve performances lifetimes competitive with proton or liquid alkaline electrolyzers, however, improvements integration materials into electrode assembly (MEA) are needed. In particular, oxygen evolution reaction (OER) catalyst,...
Recent studies have shown the potential of photosensitizer chemistry humic acid, as a proxy for humic-like substances in atmospheric aerosols, to contribute secondary organic aerosol mass. The mechanism requires particle-phase acid absorb solar radiation and become photoexcited, then directly or indirectly oxidize volatile compound (VOC), resulting lower volatility product particle phase. We performed experiments photochemical chamber, with aerosol-phase limonene VOC. In presence 26 ppb...
Renewable energy-driven bipolar membrane water electrolyzers (BPMWEs) are a promising technology for sustainable production of hydrogen from seawater and other impure sources. Here, we present protocol assembling BPMWEs operating them in range feedstocks, including ultra-pure deionized seawater. We describe steps electrode assembly preparation, electrolyzer assembly, electrochemical evaluation. For complete details on the use execution this protocol, please refer to Marin et al. (2023).
Inexpensive in situ monitoring of a conformational change macro object over long periods time chemical reactor is challenging. One research area which would benefit from improvements screening methods the study smart hydrogels, particularly when they are intended as oral forms for drug delivery or multifunctional scaffolds replacing surgically removed tissues. Smart materials have ability to alter their volume by swelling and/or collapsing response specific stimulus environment. Conventional...
The electric double layer is a highly dynamic and complex region with consequential effect on electrocatalyst performance. plethora of processes in this near-electrode microenvironment are function the catalyst material, electrolyte composition, potential range, temperature among others. For electrochemical oxygen reduction reaction (ORR) acidic media, perchloric acid commonly used as fundamental studies due to perchlorate anion’s minimal interaction most metal catalysts compared other...
