Summary: This study investigated the effect of completely exchanging Ca2+ ions with Zn2+ ions on the structure of brushite. The results showed that Ca is partially substituted by Zn when the Zn/Ca ratio is below 0.25 and that Zn doping hinders brushite crystallization. Increasing the Zn/Ca ratio led to the formation of biphasic compounds and different minerals. Adjusting the Zn/Ca ratio in the starting solution can be used to obtain minerals with specific compositions, allowing for the production of biomaterials with desired characteristics.

Summary: In this study, CaP coatings were prepared on the surface of an AZ31B magnesium alloy using electroplating to slow down the degradation rate of the alloy. The effect of plating temperature on the properties of the coatings was investigated through experimental techniques and molecular dynamics simulation. The coatings prepared at 60 degrees C had higher corrosion resistance compared to coatings prepared at other temperatures. MD simulation revealed the interfacial binding mechanism and explained the corrosion resistance and bonding force of the coatings prepared at 60 degrees C.

Summary: Cu-doped amorphous calcium phosphate (ACP) coatings were fabricated on pure titanium surfaces by electrochemical deposition at initial electrolyte temperatures of 35, 45, and 55 °C. The Cu concentration on the surfaces of the samples increased from 6.90 to 15.05 mass% as the initial electrolyte temperature increased. The Cu-doped ACP coatings showed strong antibacterial activity, completely inhibiting the growth of Escherichia coli.

Summary: In this study, a micro-arc oxidation (MAO) process with calcium was introduced to improve the interfacial strength of Titanium with a bioceramic hydroxyapatite (HA) coating. The MAO coating comprised porous TiO2 with Ca or CaTiO3, and the HA coating on the MAO coating was confirmed to be plate-like Ca-deficient HA. The MAO coating containing Ca as a connecting interlayer showed promising results in improving the HA adhesion strength with an adhesive strength of 2.326 MPa.

Summary: Calcium phosphate-based coatings have been extensively studied in orthopedics and dentistry for their similar composition to bone minerals and their ability to promote osseointegration. This study compared different calcium phosphate-based nanostructured coatings obtained from hydroxyapatite, brushite, and beta-tricalcium phosphate precursors. The coatings were systematically evaluated for their composition, morphology, physical and mechanical properties, dissolution, and in vitro behavior. High-temperature depositions were also investigated to further modify the mechanical properties and stability of the coatings. The findings demonstrate that different phosphates can be deposited with good composition fidelity and that brushite exhibits the highest suitability for promoting cell viability.

Summary: Scientists have identified two main paths for orthopedic implant fabrication, either searching for new materials with properties closest to natural bone or creating individually adapted geometry with Rapid Prototyping methods. PEEK GRF30 and Ti6Al4V SLM are materials of interest, but further research is needed to fully understand their bioactivity. The study found that both materials exhibited bioactivity comparable to Ti6Al4V, showing promising potential for orthopedic implants.

Summary: Alkali modification of apricot shells increased porosity and total surface area, as well as crystallite size and crystallinity index. Although the cellulose-rich fraction from the modified sample exhibited higher thermal stability, overall thermal analysis indicated lower thermal stability of the alkali-modified biomass. This suggests that this modification can enhance the fuel properties of apricot shell biomass and has potential applications in energy recovery.

Summary: The study investigates the corrosion resistivity, bioactivity, and antibacterial activity of novel nano-amorphous calcium phosphate (ACP) composite coatings on titanium substrate with and without chitosan oligosaccharide lactate (ChOL). Results show that ACP + ChOL/TiO2 coating exhibits better corrosion stability, bioactivity, and antibacterial activity compared to ACP/TiO2 coating. The mechanism behind the antibacterial activity is believed to involve ChOL binding with bacterial cell walls, altering membrane permeability, and leading to bacterial death.

Summary: Polygonal Pt nanoparticles with characteristic and uniform size and shape were synthesized using ultrasonic spray pyrolysis (USP). Compared to commercial Pt black, the USP-synthesized Pt nanoparticles exhibited larger particle size and lower oxygen reduction reaction (ORR) activity. However, they showed less sensitivity to current perturbations at higher overpotentials, which may be attributed to their less-compact catalyst layers and uniform particle size distribution.

Summary: Previous studies have demonstrated the complexing properties of 2-(azulen-1-yldiazenyl)-5-phenyl-1,3,4-thiadiazole (T) towards heavy metals (HMs) in solution. T can also be attached to electrode surfaces to form chemically modified electrodes (T-CMEs). The films of T-CMEs exhibited insulating properties with a thickness of approximately 10 μm, an active surface area about 6 times larger than the geometrical one, and a conductivity of about 10(-6) S/cm. Voltammetric techniques revealed the reversible anodic and cathodic redox CV peaks for the polymer, while spectroelectrochemistry showed intensified charge transport through polarons due to the anodic polarization of the film.

Summary: The aim of this research is to develop a nano amorphous calcium phosphate (ACP)/chitosan oligosaccharide lactate (ChOL) coating decorated with selenium (Se) on a titanium substrate through in situ anodization/anaphoretic deposition and to investigate its immunomodulatory and anti-inflammatory effects in vivo. The research also aims to examine controlled inflammation and immunomodulation at the implant-tissue interface. The results demonstrate that the ACP/ChOL/Se coating exhibits immunomodulatory properties, characterized by the regulation of proinflammatory cytokines' gene expression, macrophage polarization, fibrous capsule formation, and vascularization in the tissue surrounding the implant.

Summary: A novel two-compartment model for drug release was proposed, using general fractional derivatives of a specific type and distributed order. Earlier models in pharmacokinetics with fractional derivatives are special cases of the proposed model. The model was applied to study the release of gentamicin from different hydrogels and coatings, and showed good agreement with experimental data. The form of the general fractional derivatives used in the model improves the approximation of experimental data with a slightly more complex numerical procedure.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
