The work aimed at studying the structural properties of Cd-doped cobalt zinc ferrite (Co0.5Zn0.5Cd0.2Fe1.8O4) prepared by simple, low-cost solid-state reaction method and characterized by XRD...

Solid solutions Ni_0.5–xCd_xZn_0.5Fe₂O₄ (x = 0, 0.15, 0.30) were prepared by solid-state synthesis and characterized by FTIR spectroscopy. The FTIR spectra of synthesized ferrites showed two absorption bands (ν₁ and ν₂) in the range 400–600 cm^–1 belonging to tetrahedral (A) and octahedral (B) interstitial sites in the spinel lattice. The force constants for tetrahedral (K_t) and octahedral sites (K_o) were determined, as well as Young’s modulus (E), rigidity modulus (G), bulk modulus (B), Debye temperature (Θ_D), and velocity of transverse (V_t) and longitudinal (V_l) elastic waves. The relevant interionic cation–anion, cation–cation distances and bond angles are also reported.

In this study we have investigated structural attribute of Co+2 doped MgFe2O4. Synthesis of Mg1-xCoxFe2O4 ferrite was carried out using co-precipitation method. The formation of spinal ferrite was confirmed through X-ray diffraction. Lattice parameter found to be 8.376748 ? and crystallite sizes in the range 180-365 ? are observed. Various parameters like dislocation density (?D); mechanical properties (strain), Hopping length {tetrahedral site (LA) and octahedral site (LB)}, Bond length (A-O and B-O), and Ionic radii (rA and rB) were reported. The W-H plot and Size-Strain plots were extensively studied and the results have been correlated.

Whether it is a plant- or animal-based bio-inspiration design, it has always been able to address one or more product/component optimisation issues. Today’s scientists or engineers look to nature for an optimal, economically viable, long-term solution. Similarly, a proposal is made in this current work to use seven different bio-inspired structures for automotive impact resistance. All seven of these structures are derived from plant and animal species and are intended to be tested for compressive loading to achieve load-bearing capacity. The work may even cater to optimisation techniques to solve the real-time problem using algorithm-based generative shape designs built using CATIA V6 in unit dimension. The samples were optimised with Rhino 7 software and then simulated with ANSYS workbench. To carry out the comparative study, an experimental work of bioprinting in fused deposition modelling (3D printing) was carried out. The goal is to compare the results across all formats and choose the best-performing concept. The results were obtained for compressive load, flexural load, and fatigue load conditions, particularly the number of life cycles, safety factor, damage tolerance, and bi-axiality indicator. When compared to previous research, the results are in good agreement. Because of their multifunctional properties combining soft and high stiffness and lightweight properties of novel materials, novel materials have many potential applications in the medical, aerospace, and automotive sectors.
