Background The field of carbon dioxide (CO2) capture is rapidly growing due to an increasing need to effectively remove CO2 from the atmosphere. New technologies are currently being developed to target CO2 in various types of sources. One particular method of CO2 capture that has gained traction in recent years is membrane-based separation, which is...

Background Ionenes contain charges in their polymer backbones, as opposed to traditional ionomers that have charges on the pendant site of the backbone. Ionenes, whether positive or negative, typically fall into two categories- either segmented or non-segmented. Segmented ionenes contain alternating hard and soft segments along the polymer backbone,...

Background Water reclamation for space flight applications (e.g., International Space Station (ISS)) requires complex engineering solutions to ensure maximum water recovery. Current vapor compression distillation (VCD) technologies are effective but produce highly concentrated brines and often cause scaling within a separation system. Scaling in water...

­Background Removal of carbon dioxide (CO2) from the atmosphere by direct air capture (DAC) can be accomplished using two chief approaches, liquid and solid. Liquid systems pass air through chemical solutions containing basic ions (e.g., hydroxide ions or bicarbonate ions), heat the resulting mixture to release the captured CO2, and then reuse the...

­Potential Applications • High-performance CO2 direct air capture (DAC) Benefits and Advantages • Cost effective and readily scalable • Easy to fabricate into various shapes with virtually any sorbent type • Short preparation time (10 minutes for two layers of adhesive film) • Regenerable and maintains...
