• . The XRD pattern for cubic TiN, as compared to JCPDS # 87-0633, displays characteristic peaks at approximately 37°, 43°, 62°, 74°, and 78°. In contrast, the TiN processed by non-thermal plasma exhibited small shifts towards less positive values in the 2θ angles for the (111), (200), (220), (311), and

• substituted by O–H. Additionally, other characteristic absorption peaks of CUR and HPS were retained. These findings confirmed the successful synthesis of CUR-Fe@MnO2 NFs. According to the X-ray diffraction (XRD) pattern (Figure 2g), the 2θ diffraction peaks at 30.1° (220), 35.4° (311), 37.0° (222), 43.1
