Summary: Novel hydrothermal methods assisted by hydroxyapatite were used to solidify heavy metals in fly ash, resulting in hydrothermally-treated products that meet landfilling standards. The solidification mechanism involved the formation of stable compounds between hydroxyapatite and heavy metal ions. The addition of hydroxyapatite seed crystal improved the solidification efficiency.

Summary: Ultralong hydroxyapatite (HAP) nanowires have potential biomedical applications due to their similarity to bone composition and excellent properties. However, controlling their formation and the long synthesis time have been challenging. This study introduces an eco-friendly microwave hydrothermal method that uses adenosine 5'-triphosphate (ATP) as a bio-phosphorus source and water as the only solvent for rapid synthesis of ultralong HAP nanowires. The resulting nanowires show high flexibility, self-assemble into bundles, and have excellent bioactivity on chitosan scaffolds.

Summary: Microwave-assisted hydrothermal synthesis of partially substituted silicon hydroxyapatite nanopowders was investigated. The experiments showed silicon incorporation into the hydroxyapatite lattice by replacing phosphate groups with silicate groups. Excess silicon content led to reduced particle growth and self-assembly of fine rod-shaped particles into agglomerates.

Summary: This study successfully precipitated calcium deficient hydroxyapatite nanoparticles using only dilute solutions of calcium hydroxide and phosphoric acid without pH adjustment or additional chemicals. By changing the production system and hydrodynamics, pure phase hydroxyapatite nanoparticles in desired morphologies were produced, demonstrating the possibility of controlling particle characteristics without the need for additives. The vortex reactor (VR) and semi-batch reactor (SBR) produced rod-like and spherical particles, respectively, with different crystallite sizes.

Summary: The purpose of this study was to synthesize economic calcium phosphate powders from recycled oyster shells using a ball milling method. Oyster shell powder and calcium pyrophosphate powder were ball milled and heat treated to produce calcium phosphate powders. Mesoporous silicon microparticles synthesized electrochemically were added to the prepared phosphate powders. Analysis using X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy was conducted to determine the chemical composition and process conditions. The produced powders exhibited good biocompatibility according to in vitro testing with murine cells.

Summary: This paper investigates the properties of polymer-ceramic composites based on poly (L-lactide) (PLLA) with the addition of hydroxyapatite (HAp) whiskers. The results show that the processing path affects the properties of the filler particles, and the obtained composites have good strength parameters and slightly improved surface properties. The biological evaluation reveals low cytotoxicity and high colonization level for all materials, except for the composite with 10% HAp which has weaker fibroblast adhesion and higher colonization level by Staphylococcus aureus with increasing HAp content.

Summary: This in vitro study aimed to assess the impact of microabrasive blasting on the physicochemical properties of dentine and shear bond strength. The results showed that microabrasive blasting caused changes in the dentine surface and improved the bond strength with self-adhesive resin cement. Therefore, air microabrasion is recommended as a pretreatment method in fixed prosthodontics adhesive cementation protocols.

Essential oils (EOs), as a type of important prodrugs, possess high biological activity but face challenges in stability and solubility. Nanomedicine, utilizing nanotechnology, provides potential solutions for these challenges by enhancing solubility, targeting properties, and controlled delivery of EOs. The potential of EOs as anticancer prodrugs is significant but not fully explored.

Summary: In this study, two types of magnetite nanoparticles were synthesized and characterized. Both types of nanoparticles exhibited nanoscale particle sizes and superparamagnetic properties. The presence of PSA functional groups in the modified magnetite was confirmed, resulting in a lower pH of the isoelectric point. Both types of magnetite showed effective metal ion adsorption, with slight differences in their ability to adsorb cations and anions. The adsorption processes were well-described by the Langmuir and Freundlich models, with chemisorption identified as the predominant process. The adsorption of all metal ions followed a pseudo-second-order kinetic model.
