“…The VSM analysis is the dominant method for studying the magnetic properties of materials [93] and the magnetic functionality of WO 3 -NS is displayed in Figure 8. The result of this analysis can provide a hysteresis curve or material residue loop that can be used to determine the magnetic classification of materials such as ferro, anti, and paramagnetic.…”

In the present work, the synthesis of tungsten oxide nanosheets (WO 3 -NS) was performed through a sol-gel method with the usage of Na 2 WO 4 as the tungsten source in a gelatin solution that functioned as a novel green stabilising agent. The synthesised WO 3 -NS were characterised by the analysing methods of XRD, FESEM/EDX, FTIR, TGA/DTG, UVvis, Raman, and VSM. The photocatalytic activity of the product is investigated through the exertion of methylene blue pigment, while the obtained results reported 95% of degradation in 187 min under the light of a mercury vapour lamp. The cytotoxicity effect of WO 3 -NS on the human liver (Huh-7) cell line was evaluated by the means of the MTT method, which displayed the inhibiting capabilities of these nanosheets regarding cancer cells.

“…Accordingly, the complex permeability and permittivity are the key factors influencing the microwave attenuations given by the transmission line theory . Thus, polyaniline, SiC, polypyrrole, polythiophene, and carbon nanotube due to the dielectric properties and magnetic materials such as spinel ferrites_ENREF_16, hexagonal ferrites, Fe 0 , Co, and Ni have attracted considerable attentions. Among the dielectric materials, the 2D structures including graphene, MXenes, and graphite‐like carbon nitride play the vital role for microwave absorption and electromagnetic interference shielding.…”

In this study, simple, broadband, robust, and affordable microwave absorbing nanocomposites are prepared using CuCr2O4 nanoparticles as guests and silicone rubber or poly(vinylidene fluoride) (PVDF) as host. Firstly, the pristine and modified CuCr2O4 nanoparticles are obtained by the conventional citrate gel method in the absence and presence of sucrose as a novel capping agent in the experimental steps. X‐ray powder diffraction (XRD) patterns confirms that the CuCr2O4 nanoparticles are synthesized. Moreover, morphologies, chemical functional groups, and optical properties are studied using field emission scanning electron microscopy (FE‐SEM), Fourier transform infrared (FT‐IR), and diffuse reflection spectroscopy (DRS), respectively. The vibrating sample magnetometer (VSM) analysis reveals weak magnetic properties for the nanoparticles and confirms that the capping agent change the magnetic properties. Finally, bare and modified copper chromium oxide nanoparticles are separately molded with silicone rubber or PVDF to compare dipole and interfacial polarization. Besides, using a vector network analyzer (VNA) along the x and ku‐band frequency, novel organic precursor effects on their microwave absorption properties are examined. According to the obtained results, the maximum reflection loss of the modified CuCr2O4/PVDF is −65.57 dB at 14 GHz with 2 mm thickness and the CuCr2O4/PVDF nanocomposite absorbs a bandwidth of 7.73 GHz more than 10 dB with a thickness of 2 mm. Interestingly, novel one type filler lead to significant microwave absorbing properties as well as organic capping agent reinforced maximum microwave absorption also PVDF improves absorption bandwidth.
