Carbon nanotubes (CNTs) are recognized as superior material due to their remarkable mechanical, electrical, and thermal properties. These unprecedented characteristics make them ideal for a wide range of applications in fields such as electronics, energy storage, and aerospace. Breakthroughs in CNT synthesis and processing technologies have resulte

In this study, we present a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) modified with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first immobilizing SWCNTs onto a suitable substrate and then incorporating Fe3O4 nanoparticles upconverting nanoparticles
