Summary: A novel and efficient mesoporous nano-absorbent, PDA-GO/HAP, was developed through biomimetic mineralization. It exhibited rapid and efficient U(VI) removal with high adsorption capacity, attributed to the synergistic effect of functional groups and the incorporation of uranyl ions. The adsorption process was well-fitted with pseudo-second-order kinetic and Langmuir isotherm model, and showed good adsorption performance and thermal stability in a broad range of pH values.

Summary: This study presents a facile synthesis of bismuth and iron co-doped hydroxyapatite nanomaterials for high-performance fluoride ions adsorption. The nanomaterials exhibited excellent fluoride ion adsorption performance, as confirmed by batch adsorption experiments. The synthesized material showed a chemical process of fluoride uptake forming a monolayer, with homogenous surface. The proposed defluoridation mechanisms were electrostatic interaction and ion exchange. The ease of synthesis and the attractive fluoride adsorption performance make this nanomaterial promising for water treatment and environmental remediation applications.

Summary: This study successfully synthesized nano-hydroxyapatite biomimetically and found that the morphology, crystallinity, and specific surface area of the synthesized CS/HAP nanorods influenced their U(VI) adsorption efficiency. The CS/HAP-40 with smaller particle size, lower crystallinity, and larger specific surface area exhibited higher removal efficiency for U(VI). Additionally, the removal mechanism of U(VI) in acidic and alkaline solutions differed.

Summary: Biomimicry has been adopted in bioceramics due to its functional advantages. In this study, hydroxyapatite synthesized via biomimetic approach was substituted with individual and multiple cations. The substituted hydroxyapatite showed decreased crystallinity, phase purity, and altered morphology. The co-substituted hydroxyapatite with 1% Sr, Zn, and Mg showed promising biocompatibility.

Summary: The study found that the adsorption and catalytic efficiency of HAp can be controlled by changing its crystallographic properties, with TiO2 significantly affecting the Zeta potential of HAp. The synthesis of needle-shaped HAp crystals with TiO2 nanoparticles through solvothermal treatment using isopropanol at different concentrations showed a decrease in aspect ratio as isopropanol concentration increased, resulting in reduced adsorption of acidic acid fuchsin dye but slightly increased photocatalytic decolouration rate.

Summary: This study developed a robust hydroxyapatite (HAp) coating on polyetheretherketone (PEEK) using a phase-transitioned lysozyme (PTL) nanofilm as a sandwiched layer. The HAp@PTL@PEEK coating showed higher adhesion strength, better stability, and enhanced osteogenic capacity. The coating offers a novel method to improve the osseointegration of PEEK-based implants.
