Sep 1, 2020 · In the present work, we have characterized the crystalline spherulites of neat and formulated HDPE compositions thoroughly characterized by different electron microscopy techniques such as scanning electron microscopy (SEM) …

Feb 13, 2020 · Optical images and SEM-EDX analysis showed the well-maintained spherulite superstructure, and the metal composition was analyzed by ICP-MS, showing 92.0% Zn, 2.6% Ni, and 5.4% Co dispersed in the hierarchical structure (Figures 5 A and 5B).

Nov 19, 2014 · We describe in detail how the spherulites and axialites can be identified using X-ray CT with the assistance of scanning electron microscopy (SEM).

Mar 2, 2025 · The morphology and elemental analysis of the new nickel-containing l-glutamine spherulite complex was investigated by Scanning Electron Microscopy (SEM), using the Zeiss EVO 15 microscope, equipped with a Bruker XFlash 410-M EDS detector.

Aug 20, 2022 · Our data on astigmatism-based 3D direct stochastic optical reconstruction microscopy (dSTORM) 35, spinning disk confocal microscopy 36, and scanning electron microscopy (SEM) confirm that the...

Distributions of Cristobalite and plagioclase in a spherulite mineral have been visualized by SEM, CL, and EDX. The outer layer of the spherulite is comprised of plagioclase and Cristobalite texture having fiber-like fine structure.

Jan 17, 2025 · High-resolution SEM imaging of the flower-like structure highlights densely packed, edge-on lamellae with lobed rims, forming a dome-shaped surface, while the zigzag spherulites exhibit dendritic, periodic growth from the nucleus, with …

Aug 25, 2024 · The present research demonstrates, in three different semicrystalline polymers (HDPE, PEG10000 and Pluronic F-127), that sequential transcrystallinity is the predominant mechanism of banded spherulite formation, heterogeneously nucleated on intermittent self-shear-oriented amorphous layers excluded during the crystals’ growth.

Sep 2, 2016 · Spherulites in general have spherical symmetry, but crystal properties are anisotropic in the radial and tangential directions. Cracks and ring-banded morphology in semicrystalline polymers have been extensively investigated and widely reported in the literature.

Mar 1, 2021 · When supermolecular structures are no longer observable by light microscopy, SEM or AFM are used most in polymer physics research. In SEM images (Fig. 12), in addition to the spherulitic structures, the lamellar structure can also be studied.
