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: Hydroxyapatite (HAP) is an effective material for removing excess fluoride from water. This study demonstrates the internalization of fluoride in HAP nanoparticles under environmentally relevant conditions and provides a model to quantify adsorption and total fluoride capacity. The discrepancies between experimental uptake and adsorption capacity indicate the range of fluoride that internalizes to satisfy conservation of mass.

Summary: HAP aerogels with higher adsorption speed and capacity were successfully synthesized using konjac gum as a template through a combination of freeze-drying and template methods. Of these, B-HAP aerogel prepared with 0.25 g konjac gum as a template showed better micro morphology and structure, resulting in more available sites for uranium immobilization. B-HAP demonstrated a uranium removal efficiency of 99.4% within 10 min and a maximum removal capacity of 2055.2 mg g(-1), surpassing other reported adsorbents. The adsorption behavior on HAP aerogels was best described by the pseudo-second-order and Langmuir models, suggesting that uranium ions were immobilized on HAP aerogels via chemical adsorption. B-HAP also exhibited high selectivity, stability, and durability, making it a promising candidate for uranium extraction from wastewater.

Summary: This study focused on using phytoremediation technology from marine microalgae Dunaliella salina to remove fluoride ions from aqueous solution. The physical characteristics, functional groups, and surface microstructure of the microalgae were analyzed, and the removal of fluoride was optimized through various conditions and methods. The study showed that microalgae are a novel, low-cost, and effective bio-based method for the bioremediation of fluoride from water bodies and industrial wastewaters.

Summary: This study evaluated the cytotoxicity, chemical and structural properties of fluoride-doped calcium-phosphates as potential remineralising materials for dental applications. Experimental calcium phosphates were tested for their ability to crystallise into apatite-like and their fluoride release. The materials showed biocompatibility and the ability to promote cell proliferation, indicating their potential use as remineralising materials in dentistry.

Summary: This study utilized solid-state magic angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy to investigate the formation of fluoride compounds in bovine enamel and dentin treated with silver diammine fluoride (SDF). The results revealed that SDF exhibited increased reactivity with dentin, leading to the formation of fluorhydroxyapatite (FHAp) and other fluoride compounds. Scanning electron microscopy (SEM) observations also showed pronounced precipitation and particle formation in dentin treated with SDF.

Summary: In this study, strontium-doped hydroxyapatite (Sr-HAP) was synthesized and found to have higher adsorption capacity for lead ions. Increasing the dosage and temperature enhanced the adsorption capacity. Sr-HAP had increased specific surface area and more uniform pore size distribution, making it an ideal adsorbent for removing lead ions from wastewater.

Summary: A recent study explores a method to measure high-dose electron radiation using phosphors with dose-dependent luminescence. SrF2 nanoparticles codoped with Yb and either Er, Hm, or Tm were synthesized and their dose response and fading behavior after irradiation were measured. Spectroscopy, diffraction, and calculations were used to explain the effects of irradiation and propose the formation of a secondary phase.
