“…Hence, the formation of cations with different ionic radius leads to the creation of real crystals. In particular, the oxygen atoms are liberated from their normal sites to create the empty site for the cations with the larger ionic radius [35]. This examination was good agreements with the XRD analysis for the creation of single phases before and after the inclusion of samarium NPs into the CoFe 2 − x Sm x O 4 composite.…”

Herein, we present the design and fabrication of samarium (Sm3+) doped cobalt-iron oxide ferrites nanocomposites for utilization as an efficient energy storage material. We have employed a simple, low cost and quick one step solution combustion method used to synthesize CoFe2 − xSmxO4 (x = 0.0, 0.050, 0.075 and 0.1) ferrites composites. The synthesized CoFe2 − xSmxO4 NPs undergo different analytical and spectroscopic characterizations methods like scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and ultraviolet visible (UV-visible) analytical and spectroscopic methods that used to confirm the morphological and structural properties of the synthesized NPs. The electrochemical properties synthesized ferrites composites were significantly improved after inclusion of rare earth (RE) metal such as samaniuim (Sm3+) nanoparticles (NPs) into the host cobalt-iron-oxide. It was notice that the creation of single phase in pure CoFe2 − xSmxO4 ferrite remains unaltered by the mechanism of doping even in the ferrites composite. Nevertheless, doping of RE metal significantly influences over the morphological and structural properties, further more enhancement in the electrochemical performance of samarium doped CoFe2 − xSmxO4 ferrite composite. The highest specific capacity about 850 F/g was achieved for CoFe2 − xSmxO4 (x = 0.1) composite electrode material, which shows more superior in compare to pure CoFe2 − xSmxO4 (x = 0) which is about 340 F/g. However, CoFe2 − xSmxO4 (x = 0.1) composite shows a superior capacitance retention of the order of 98% even after 5000 cycles of operation at a scan rate of 250 mV/s. The electrode material fabricated by using CoFe2 − xSmxO4 ferrite composites behave as positive electrode and at the same time activated nickel behave as negative electrode which is render an energy density of 30.16 Wh/kg at a power density of 400 Wh/kg. The results obtained in presented studies offer a hopeful way for the fabrication high-performance electrode material for supercapacitor which is more suitable for light weight electronic devices, electric vehicles, and forthcoming generation supercapacitor applications.

“…Also some oxygen defects in the spinel ferrite structure can also get introduced, due to which a slight shifting of the ions takes place, which can change the bond lengths. 15,16 Earlier works on yttrium-substituted cobalt ferrites has already been established and many scientists have worked on this area and utilized such materials for various applications, like gas sensors, conducting multilayer chips, high-frequency devices, superconductors, microwave devices, and high-density recording media. Hasim et al discussed that the co-substitution of cerium and dysprosium in cobalt ferrites can improve their electrical and magnetic properties.…”

MXene aerogels have shown great potential for many important functional applications, in particular electromagnetic interference (EMI) shielding. However, it has been a grand challenge to create mechanically hyperelastic, air‐stable, and durable MXene aerogels for enabling effective EMI protection at low concentrations due to the difficulties in achieving tailorable porous structures, excellent mechanical elasticity, and desired antioxidation capabilities of MXene in air. Here, a facile strategy for fabricating MXene composite aerogels by co‐assembling MXene and cellulose nanofibers during freeze‐drying followed by surface encapsulation with fire‐retardant thermoplastic polyurethane (TPU) is reported. Because of the maximum utilization of pore structures of MXene, and conductive loss enhanced by multiple internal reflections, as‐prepared aerogel with 3.14 wt% of MXene exhibits an exceptionally high EMI shielding effectiveness of 93.5 dB, and an ultra‐high MXene utilization efficiency of 2977.71 dB g g−1, tripling the values in previous works. Owing to the presence of multiple hydrogen bonding and the TPU elastomer, the aerogel exhibits a hyperelastic feature with additional strength, excellent stability, superior durability, and high fire safety. This study provides a facile strategy for creating multifunctional aerogels with great potential for applications in EMI protection, wearable devices, thermal management, pressure sensing, and intelligent fire monitoring.
