    SEM A and STEM B cross sectional image showing the 5-layered nanocomposite structure with alternate silica and carbon black layers after heating treatment at more than 800 °C. B HAADF image and intensity profiles for carbon and silicon show the interfaces between substrate and coated silica layers on the right and the sugar-derived carbon layer between two silica layers on the left. The thickness of the carbon layer is estimated to be ~ 10–20 nm based on the spike of carbon signal. Credit: MRS Advances (2022). DOI: 10.1557/s43580-022-00245-y
