Unravelling intercalation-regulated nanoconfinement for durably ultrafast sieving graphene oxide membranes

Laminated graphene oxide membrane for recovery of mercury-containing wastewater by pervaporation

“…For the spectrum of c-GO-PEI, characteristic peaks of N − H can be seen at 1586 cm −1 , and C − H can be seen at 2842 and 2963 cm −1 , confirming the existence of PEI and the formation of cross-linking structure in the membrane. (Guo et al 2021;Halakoo and Feng 2020;Qian et al 2018) In XPS N1s spectrum (Fig. 3b), the fitted peaks represent C − N at 399.0 eV, N − C = O at 400.1 eV and tertiary N at 401.3 eV, which confirms the successful intercalation of PEI in the GO membrane.…”

Development of a pH-sensitive functionalized metal organic framework:in vitrostudy for simultaneous delivery of doxorubicin and cyclophosphamide in breast cancer

“…Besides, the (002) peak in the XRD spectrum of GO-FA, was narrower than that of pristine GO with decreased peak intensity, revealing a more aligned stacking of GO nano sheet and emergence of FA molecules. 65,66 It is reported that the emergence of peak at 18.6 due to certain degree of reduction by DETA and peaks at 31 and 45 belonging to the FA crystal structure during modication. 59,67 So that in XRD image, it is clearly visualized that GO sheets exfoliated by DETA and decorated by FA.…”

Ultrafast Water Transport in Two‐Dimensional Channels Enabled by Spherical Polyelectrolyte Brushes with Controllable Flexibility

“…As a result, well‐stacked SPB/GO membranes were obtained, which contributed to the membrane separation process. Meanwhile, Shao et al [17] . revealed that large‐sized molecules inhibit the overlap of GO nanosheets, resulting in lower degree of alignment and shorter transmembrane pathway.…”
