摘要： An active CO2 capture unit for capturing CO2 from a dilute source of CO2 input gas can include an inlet through which an input gas is introduced into the unit and a non-aqueous region comprising a non-aqueous CO2 binding organic liquid containing OH− arranged to be in contact with the input gas to chemisorb CO2 from the input gas and convert the chemisorbed CO2 into HCO3− by reacting with OH−. The unit also includes an aqueous region arranged downstream of the non-aqueous region, wherein at an aqueous region interface, the HCO3− interacts with H2O and decomposes to CO2 and CO32−. An anion exchange membrane is disposed between the non-aqueous region and the aqueous region to facilitate HCO3− diffusion and migration from the non-aqueous region to the aqueous region. A captured CO2 outlet is disposed downstream of the aqueous region.

摘要： The disclosure relates to a microfluidic system for the screening of polymorphs, morphology, and crystallization kinetics under well-mixed, continuous-flow at controlled supersaturations. The disclosure also relates to a method for screening crystalline polymorphs and morphology, and crystallization kinetics. The microfluidic system includes a microfluidic chamber having one or more inlets, a passive mixing zone, and a trap zone. The passive mixing zone promotes mixing of solvent, solute, and optionally antisolvent under stable, controlled levels of supersaturation. The trap zone similarly has stable, controlled levels of supersaturation and correspondingly low velocity to retain solute crystals formed in the trap zone for time-dependent evaluation.
