The AIHs are formed in 300 seconds by mixing hydrogel particles with liquid amine (left) which increases the contact area between the CO2 and the amine (right).
A new class of CO2 sorbents, namely polyethylenimine hydrogel beads (PEI HBs), has been developed via a simple one-step crosslinking reaction of PEI using epichlorohydrin (EPC).
Karrikins (2H-furo[2,3-c]pyran-2-ones) are potent smoke-derived germination promoters for a diverse range of plant species but, to date, their mode of action remains unknown. This paper reports the structure-activity relationship of numerous karrikin analogues to increase understanding of the key structural features of the molecule that are required for biological activity. The results demonstrate that modification at the C5 position is preferred over modification at the C3, C4, or C7 positions for retaining the highest bioactivity.
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.
