Abstract:An ultrafast, continuous CO2 capture process driven by moisture gradient and electric field with low energy consumption to capture and concentrate CO2 from dilute sources.
“…In Fig. 2A of article, 1 we have already shown that a gradual increase in the bicarbonate and carbonate peaks is observed with the addition of water into the non-aqueous mixture containing NaHCO 3 . The measured concentrations of bicarbonate, carbonate, and water are used to calculate the equilibrium constant (eqn (3)), which increases sharply with an increase in water (Fig.…”

“…These calculations are already provided in Section S3 in the supplementary information of the paper. 1 Regarding the Comment that the CO 2 released due to acidification of neutral pH bicarbonate solution (eqn (2) of the Comment), we have already depicted it in Fig. 1B of the article.…”

“…Prajapati et al 1 developed a novel, robust, modular and industrially-scalable CO 2 capture process that utilizes a migration-assisted moisture gradient (MAMG) process. In the MAMG process, the CO 2 from the dilute gas source (e.g., air or flue gas) is first absorbed in a non-aqueous, alkaline, organic solution (e.g., 1 M KOH dissolved in ethylene glycol) to produce bicarbonate ions, which are then transferred selectively to an aqueous solution using electrodialysis.…”

Contemporary synthetic biology-based biotechnologies are generating tools and strategies for reprogramming genomes for specific purposes, including improvement and/or creation of microbial processes for tackling climate change. While such activities typically work well at a laboratory or bioreactor scale, the challenge of their extensive delivery to multiple spatio-temporal dimensions has hardly been tackled thus far. This state of affairs creates a research niche for what could be called
Environmental Galenics
(EG), i.e. the science and technology of releasing designed biological agents into deteriorated ecosystems for the sake of their safe and effective recovery. Such endeavour asks not just for an optimal performance of the biological activity at stake, but also the material form and formulation of the agents, their propagation and their interplay with the physico-chemical scenario where they are expected to perform. EG also encompasses adopting available physical carriers of microorganisms and channels of horizontal gene transfer as potential paths for spreading beneficial activities through environmental microbiomes. While some of these propositions may sound unsettling to anti-genetically modified organisms sensitivities, they may also fall under the tag of TINA (there is no alternative) technologies in the cases where a mere reduction of emissions will not help the revitalization of irreversibly lost ecosystems.

“…In the case of absorbents, an electrodialysis system that can operate under ambient conditions has been reported by using an anion exchange membrane that separates organic solvents and aqueous solutions. 22 Many CO 2 capture studies have been conducted; however, most of them are carried out with adsorbents based on the existing solid materials.…”
Emulsion solvents (ES), which are liquid absorbent-based CO2 capture materials, are developed as simple and expandable droplets to control CO2 capture performance. An aqueous NaOH solution, which is a chemical...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
