I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Two-dimensional metal-organic framework nanosheets: synthesis and applications.
TL;DR: This review summarizes the recent advances in the synthesis of 2D MOF nanosheets by using top-down methods, e.g. sonication exfoliation, mechanical ex foliation, Li-intercalation exfoliated and chemical exfolation, and bottom-up methods, i.e. interfacial synthesis, three-layer synthesis, surfactant-assisted synthesis, modulated synthesis, and sonication synthesis.

Ultrathin metal/covalent-organic framework membranes towards ultimate separation.
TL;DR: The advanced strategies in fabricating ultrathin defect-free MOF/COF membranes such as in situ growth, contra-diffusion method, layer-by-layer (LBL) assembly, metal-based precursor as the pre-functionalized layer, interface-assisted strategy, and laminated assembly of MOF-COF nanosheets are presented.

Physical Aging, Plasticization and Their Effects on Gas Permeation in "Rigid" Polymers of Intrinsic Microporosity
TL;DR: In this paper, a triptycene-based ladder polymer (TPIM-1) exhibited very large selectivity gains outweighing permeability losses after 780 days, resulting in unprecedented performance for O2/N2 (P(O2) = 61 Barrer, α(O 2/N 2) = 86) and H2/H2/NB 2 (H2 2 ) = 1105 Barrer and α(H 2/NB 3 ) = 156) separations.
