Characterization of nanocomposite

XRD and FTIR studies

The XRD spectra of the nanomaterials are displayed in Fig. 2, where a distinctive broad peak at 19.69° is displayed by sephadex. 7.3°, 10.4°, 12.7°, 14.7°, 16.5°, 18.0°, 22.1°, 24.5°,…

Catalyst characterization

The XRD patterns in Fig. 1a illustrate the crystalline structural properties of ZSM-5 supported phosphomolybdic acid catalysts with varying catalyst loadings. As the phosphomolybdic acid dosage on ZSM-5 increased, a…

In this study, the low-temperature life time (LT) of ceramic electrets polarized at Tp = 300–500 ℃ was experimentally confirmed to be semi-permanent by non-destructive Vs measurements and destructive TSDC, XRD, and spectroscopic analyses….

Imaging of uncoated and platinum black coated electrodes

The uncoated platinum electrodes were light grey pads attached to the flexible nitinol stent while platinum black coated electrodes were a darker colour. Under HIM (Fig. 3a–d), the…
