The rapidly increasing atmospheric CO concentration has driven research into the development of cost- and energy-efficient materials and processes for the direct air capture of CO (DAC). Solid-supported amine materials can give high CO uptakes and acceptable sorption kinetics, but they are generally prepared in powder forms that are likely not practically deployable in large-scale operations due to significant pressure drops associated with packed-bed gas-solid contactors. To this end, the development of effective gas-solid contactors for CO capture technologies is important to allow processing high flow rates of gas with low-pressure drops and high mass transfer rates.

We provide a perspective on the development of direct air capture (DAC) as a leading candidate for implementing negative emissions technology (NET). We introduce DAC based on sorption, both liquid and solid, and draw attention to challenges that these technologies will face. We provide an analysis of the limiting mass transfer in the liquid and solid systems and highlight the differences.

Aims: The authors sought to assess the changes in eyelid position after silicone tube insertion and removal in endoscopic dacryocys-torhinostomy.

Methods: The authors retrospectively reviewed 60 eyes of 48 consecutive patients who underwent endoscopic dacryocystorhinostomy operation at Korea University Guro Hospital, Seoul, Republic of Korea, between April 2019 and November 2019. All cases were evaluated to discern eyelid positioning, focusing on the marginal reflex distance 1, medial palpebral fissure, central palpebral fissure (PF-2), lateral palpebral fissure (PF-3), and medial canthal angle (MCA) before surgery and at 1 week and 1, 2, 3, and 4 months postoperatively.
