HAP (Hydroxyapatite) bio-composite has been used extensively to repair and replace bone and teeth tissues in the human body. However, because of the poor mechanical features of HAP bio-composites, significant enhancements in the strength and toughness of pure HAP have been achieved by the insertion of various alloys and materials into HAP. Accordingly, the present study evaluates the radiation shielding and mechanical features of the Fe2O3 -reinforced HAP composite as an implant for 0.0, 2.5, 5.0, and 7.5 wt.% Fe2O3. Also, the composite response in a magnetic field has been investigated. Employing FLUKA Monte Carlo Code, radiation shielding factors are obtained. In addition, the mechanical characteristics of the studied composites are evaluated using the theoretical method. Findings reveal that increasing the Fe2O3 contents in HAP bio-composite enhances the preferred samples’ radiation shielding and mechanical qualities. Furthermore, in the absence of a magnetic field, the particles' spatial map exhibits symmetric behavior along the x-axis, however, a different trend is observed in the presence of a magnetic field with a value of Bx=5 microT.

“…The cost, noncorrosive, eco-friendly properties, high transparency, non-toxic nature, and good mechanical features are the advantages of using glasses as shielding materials.

Understanding the influence of rare-earth ions in tellurite-rich glass is vital for developing the technology. With this motivation, the present study analyzes the radiation shielding, physical, structural, mechanical, and acoustic features of the tellurite glasses added Nd 2 O 3 rare earth material. Five different glasses coded as TMNd0.0-TMNd1.9 are simulated via MCNPX Monte Carlo code by varying the concentration of neodymium oxide (Nd 2 O 3 ) and the related characteristics are evaluated between 0.01 and 10 MeV. The obtained results reveal that Nd 2 O 3 has a favorable influence on the radiation shielding characteristics of the preferred glass sample. To assess the relation between Nd 2 O 3 concentration in tellurite glass and corresponding structural and mechanical changes in candidate glasses, Makishima-Mackenzie theory is applied and mechanical moduli are extracted. The structure and dimensionality of the preferred samples are derived based on the Bergman and Kantor model for fluid and compositions with the help of the fractal bond connectivity. In addition, the longitudinal velocity (V L ), transverse velocity (V S ), mean velocity (V mean ), and acoustic impedance (Z i ) related to the TMNd glasses are evaluated.

“…Calcium phosphates (CPs) are highly biocompatible [1][2][3][4], osteoconductive [2][3][4], and non-toxic [2] ceramic materials. Due to their excellent biological properties, calcium phosphates arouse wide interest from the point of view of medical applications, mainly as components of systems for bone regeneration [1], or a part of an artificial bone [5]. In dentistry, they found application as components of products inducing remineralization, i.e.…”

Insufficient mechanical properties of hydroxyapatite-based composites prompted the search for new and effective solutions for dental applications. To improve the mechanical properties without losing the remineralization potential, the use of hybrid fillers was proposed. The first of them was based on the formation of hydroxyapatite (HA) layer on the surface of SYLOID®244 silica. The second of the investigated fillers was created by simultaneous synthesis of nanoparticles from precursors of HA and silica. The obtained fillers were extensively characterized by spectral methods including X-ray Diffractometry (XRD), Fourier-Transform Infrared Spectroscopy (FT-IR), and X-ray fluorescence (XRF), as well as by Scanning Electron Microscopy (SEM)/Energy Dispersive Spectroscopy (EDS). Tests using probiotic microorganisms were an important part of the analysis, indicating that there was no potential interaction of the materials with microflora. The tests of degree of conversion, depth of cure, opacity, sorption, solubility, flexural and compressive strength, and the remineralizing potential also showed that the composites with nano-sized silica/HA showed better mechanical properties than the composites with HA alone or commercial silica and at the same time the remineralization remained at the desired level. Thus, the proposed composite has a high application potential in the creation of implants and dental materials. Graphical abstract
