In this paper, CoNi/SiO₂ hybrids are synthesized for high-performance MA by anchoring the dielectric SiO₂ layer by Stöber's sol-gel method to regulate the permittivity (ε_r). The results show that the abundant pores and high specific surface area of the coral-like spherical structure, the ε_r modulation of CoNi alloy by SiO₂ shell-layer, the heterogeneous interface and charge storage capacity difference between both, which provide more reflective and scattering channels for the incident electromagnetic wave (EMW), optimize the impedance matching and enhance the interfacial polarization loss and magnetic loss, and finally achieve the reflection loss (RL) enhancement and effective absorption bandwidth (EAB) broadening. In particular, the coral-like CoNi@SiO₂-2 microparticle (MP) has the strongest RL of −66.59 dB at 2.2 mm matching thickness and the maximum EAB of 6.460 GHz at 1.9 mm matching thickness, which covers the entire Ku-band.

Polycaprolactone (PCL) has emerged as a viable material for the fabrication of porous bone scaffolds. Composites that incorporate PCL with ceramic phases, such as nanocrystalline hydroxyapatite (n-HA) and tricalcium phosphate (TCP), have shown promise in promoting bone formation. Nevertheless, the use of bone scaffolds with complex geometries that mimic human bone poses challenges regarding their mechanical properties, which is the primary focus of this study. To assess the mechanical behavior of triangular nanostructures, particularly their ultimate compressive strength, finite element analysis (FEA) and artificial neural network (ANN) techniques were utilized. The obtained results were compared to experimental and analytical data. Three samples with varying weight percentages (0.1, 0.2, and 0.3) of HA and TCP nanoparticles embedded in PCL polymer were fabricated using a 3D fused deposition modeling technique. Scanning electron microscope (SEM) analysis was conducted to evaluate the morphology, while apatite formation rate and weight loss in simulated body fluid (SBF) and phosphate buffer saline (PBS) solution were assessed. The results revealed that a porosity of 76 % increases the apatite formation and dissolution rates by 23 % and 39 %, respectively. The SEM images, in conjunction with the simulated FEA models, indicated that scaffolds containing 0.3 wt% TCP nanoparticles exhibited favorable mechanical and biological properties for bone fracture applications. Additionally, the influence of different weight percentages of TCP and HA on the mechanical properties of the scaffolds was investigated using ANN. A neural network model was developed by incorporating 0.2 of each additive within a range of 0.1–0.3 while evaluating output data including elastic modulus, compressive strength, tensile strength, and Poisson's ratio.

A comprehensive exploration of their crystal structure, electronic structure, and optical transition properties were conducted through a combined experimental and theoretical calculation analysis.
