Self-assembly of delaminated layered double hydroxide nanosheets for the recovery of lamellar structure

Confinement of Triple-Enzyme-Involved Antioxidant Cascade in Two-Dimensional Nanostructure

“…More details on the colloidal properties of the dLDH particles can be found elsewhere. 45 The effect of polyelectrolyte adsorption on the charge of dLDH particles was investigated in zeta potential measurements (Figure 1).…”

“…Accordingly, in an ideal two-phase structure with sharply defined phase boundaries (e.g., smooth surface of an individual lamella), the scattering intensity has an asymptotic feature (Figure S1C in the SI), while, due to electron density fluctuation or stacked structure, positive deviation from the asymptotic behavior can be observed (Figure S1D in the SI). − Interpreting the results with the Porod law (eq S6 in the SI), a slope equal to 4 at higher scattering angles ( h > 0.5 nm –1 ) clearly indicates the flat interface (i.e., an individual lamella with a smooth surface), while the deviation from the power law h –3 refers to a nondelaminated state, in which the system appears as a quasi-surface fractal.

Colorimetric transition pathway mapping in polydiacetylene by hyperspectral microscopy

“…This was enabled thanks to the spectral mapping ability of the technique with a spatial resolution that goes below the single crystal size, in contrast to the conventional ensemble measurements such as UV-VIS, IR, Raman spectroscopy, NMR, X-ray diffraction, and other imaging methods that have the spatial resolution but not the spectral information such as AFM and TEM. 45 We found that each blue undergoes a unique path to a diverse types of red structures, where a pattern, e.g. a certain blue structure prefers transforming into a certain red structure, was detected.…”

Colorimetric response in polydiacetylene at the single domain level using hyperspectral microscopy

“…This journal is © The Royal Society of Chemistry 2023 due to the spectral mapping ability of the technique with a spatial resolution that goes below the single crystal size, in contrast to conventional ensemble measurements such as UV-Vis, IR, Raman spectroscopy, NMR, X-ray diffraction, and other imaging methods that have the spatial resolution but not the spectral information such as AFM and TEM. 42 Other spectral mapping based on scanning microscopy methods, such as infrared scattering scanning near-field optical microscopy (IR-s-SNOM) 43,44 and tipenhanced Raman spectroscopy (TERS), may be an alternative tool. 45 We found that each blue structure undergoes a unique path to diverse types of red structure, where a pattern, e.g., a certain blue structure prefers to transform into a certain red structure, was detected.…”
