Background The accumulation of carbon dioxide (CO2) in the atmosphere has been documented to be the primary driver of global warming. The global average CO2 levels in the atmosphere continue to rise, with a predicted 1.5°C increase in global temperatures within the next two decades. The capture and storage of CO2 is an essential part of mitigating...

Background Anthropogenic CO2 emissions are one of the major contributing factors to climate change. Direct air capture (DAC) technologies extract CO2 directly from the atmosphere, and are one potential solution to combatting CO2 emissions. Poly(vinyl guanidine) (PVG) is a polymer that can be synthesized through free radical polymerization of vinyl...

­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...

­Background Direct air capture (DAC) is a process of capturing carbon dioxide (CO2) directly from air. The CO2 can be captured when the air contacts a chemical medium or functionalized sorbent, and then removed from the chemical medium or functionalized sorbent to yield a CO2 stream. Invention Description Researchers at Arizona State University...

­Background Carbon dioxide (CO2) emissions continue to be the major contributor of climate change. Solving this issue is a major hurdle currently facing the world. Various ionic liquids have shown promising affinity towards the selective capture of CO2. With the viscosity of the ionic liquids, its sorptive capacity for CO2 is limited by diffusion...
