Comparative study of pulpal response following direct pulp capping using synthesized fluorapatite and hydroxyapatite nanoparticles.

Objective: This study aimed to investigate and compare the histological response of rabbit dental pulp after direct pulp capping with 3 different materials: mineral trioxide aggregate (MTA), nanoparticles of fluorapatite (Nano-FA), and nanoparticles of hydroxyapatite (Nano-HA) after 4 and 6-week time intervals.

Material And Methods: A total of 72 upper and lower incisor teeth from 18 rabbits were randomly categorized into 3 groups)24 incisors from six rabbits each. MTA Group: teeth were capped with MTA.

Adsorption of Co(II) and Eu(III) radionuclides by a sustainable nanobentonite@sodium alginate@oleylamine nanocomposite.

A sustainable and efficient nanobentonite@sodium alginate@oleylamine (Nbent@Alg@OA) nanocomposite has been successfully synthesized via coating reaction of nanobentonite (Nbent) with alginate (Alg) and oleylamine (OA). The nanocomposite has been characterized and examined for the adsorption of Co(II) and Eu(III) radionuclides from simulated radioactive waste solution. FT-IR, XRD, SEM, and HR-TEM techniques have been applied to confirm the structural and morphological characteristics of the Nbent@Alg@OA nanocomposite.

A novel β-cyclodextrin/alginate-combined-nickel oxide nanosorbent for adsorptive remediation of Cr and Mn radionuclides.

A Promising nanocomposite from β-Cyclodextrin/Alginate (β-CD/Alg) composite impregnated with nickel oxide nanoparticles (NiO) has been synthesized and characterized using diverse techniques like FT-IR, XRD, TGA, and SEM. The new nanocomposite has been investigated for the efficient remediation of Cr and Mn radionuclides from simulated contaminated radioactive water. All the controlling experimental parameters such as solution pH, contact time, initial radionuclides concentration and adsorbent mass have been investigated and optimized.

Promoted adsorptive removal of chromium(vi) ions from water by a green-synthesized hybrid magnetic nanocomposite (NFeOStarch-Glu-NFeOED).

A novel magnetic starch-crosslinked-magnetic ethylenediamine nanocomposite, NFeOStarch-Glu-NFeOED, was synthesized microwave irradiation. The characteristics of the assembled NFeOStarch-Glu-NFeOED nanocomposite were evaluated XRD, FT-IR, TGA, BET, SEM and HR-TEM analyses. Its particle size was confirmed to be in the range 11.

Nano-manganese oxide-functionalized-oleyl amine as a simple and low cost nanosorbent for remediation of Zn/Co and their radioactive nuclides Zn and Co from water.

The contribution of oleyl amine as a biodegradable and simple aliphatic compound containing amine functional group (-NH) was discussed in this work with respect to the remediation process of heavy metal ions from aqueous solution. Manganese oxide nanoparticles were synthesized via combustion synthesis and then functionalized with oleyl amine to form a new nanosorbent (NMnO-OA).The characteristics of this nanosorbent were examined using different instruments, such as Fourier-transform infrared spectroscopy, thermal gravimetric analysis, X-ray powder diffraction and high-resolution transmission electron microscopy.

A novel nanocomposite of Liquidambar styraciflua fruit biochar-crosslinked-nanosilica for uranyl removal from water.

Biochar adsorption has been protruded as a sustainable green and economic process for water remediation. This technology is facing high challenges in removing different pollutants, owning to the stable chemical and physical features of biochar. Therefore, a novel nanocomposite of Liquidambar styraciflua fruit biochar-crosslinked-nanosilica (BC-Gl-NSi) was synthesized and characterized (surface area = 60.
