“…The results of the present study revealed that the incorporation of both SiO 2 -NPs and ZrO 2 -NPs insignificantly decrease the impact strength of thermoplastic resin. This may be due to that the incorporation of hard SiO 2 and ZrO 2 nanoparticles into thermoplastic resin can increase the brittleness of the samples because of limiting the free movement of the polymer chains due to interruption of intermolecular forces, which would reduce the impact strength (10,34) . Also, the inhomogeneous distribution of the nanoparticles with frequent clustering could affect the impact strength negatively (10,33,35) .…”

“…Silicon oxide nanoparticles (SiO 2 -NPs) are mostly used to reinforce the acrylic resin because of their excellent biocompatibility as well as their optical, thermal, and mechanical properties (7)(8)(9)(10) . However, zirconia oxide nanoparticles (ZrO 2 -NPs) received attention due to their white color as well as other beneficial properties such as excellent biocompatibility, toughness, and strength (9,11) .…”

Objective: This study was aimed to evaluate the effect of incorporation of two-different nanoparticles (NPs); silica (SiO 2), and zirconia (ZrO 2) on flexural strength, impact strength, as well as, water sorption and solubility of thermoplastic resin material. Materials and Methods: Two nanoparticles SiO 2-NPs, and ZrO 2-NPs (Nano-gate Company, Egypt) were incorporated into thermoplastic resin with different concentration (1.5 and 7 wt.%). This study was divided into five main groups; unmodified "control group" and four modified groups according to the type and concentration of the incorporated nanoparticles. Results: The results of this study revealed that the incorporation of 1.5 wt.% SiO 2-NPs significantly improves the flexural strength of thermoplastic resin. While the incorporation of SiO 2-NPs and ZrO 2-NPs nanoparticles insignificantly decreases its impact strength. However, they significantly increase water sorption and solubility of thermoplastic resin. Conclusion: The incorporation of nanoparticles into thermoplastic resin at different concentrations could negatively affect its flexural strength, impact strength, as well as its water sorption and solubility.

Background: One of the materials for denture bases is heat-cured acrylic resin (PMMA). This material still lacks impact strength as a mechanical strength property. The addition of reinforcing material is known to increase the mechanical strength of PMMA. One of the reinforcing materials added to PMMA is nano cellulose from rice husks, one of the wastes from agricultural products. Purpose: This study aims to determine rice husk nano cellulose's addition to the PMMA denture base's impact strength. Method: The research sample consisted of six groups, each group consisting of 8 samples selected by simple random. The PI, P2, P3, P4, P5, and K groups were PMMA with 1%, 2%, 3%, 4%, 5% nano cellulose, and without nano cellulose. Result: Mean impact strength test results were 41.50 x 10-3 ± 3.891 J / mm2 for P1, 44.13 x 10-3 ± 3,980 J / mm2 for P2, 45.63 x 10-3 ± 4,438 J / mm2 for P3, 46.87 x 10-3 ± 4,824 J / mm2 for P4, 49.12 x 10-3 ± 4.016 J / mm2 for P5 and 36.25 x 10-3 ± 1.982 J / mm2 for K. One way Anova test results with p-value of 0.000 indicates differences in the six groups (p<0.05). Conclusion: This study concludes that the impact strength value of PMMA with the addition of rice husk nano cellulose has increased compared to the control group without the addition of rice husk nano cellulose.

“…A complex constructed between a guest species and a cryptand is identified as a cryptate. The common generally applied cryptand is 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo [8.8.8] hexacosane, also termed as [2.2.2] cryptand or Kryptofix 2.2.2 [ 23 , 24 ]. The cryptands were improved by Jean-Marie Lehn, regarded as a type of crown ether derivative that has invited great interest due to its three-dimensional (3D) unique constructions and extra binding positions as presented in Figure 1 .…”

Novel Hybrid Nanoparticles: Synthesis, Functionalization, Characterization, and Their Application in the Uptake of Scandium (III)Ions from Aqueous Media

The aim of this study was to prepare novel supramolecular hybrid nanoparticles (HNPs) that can selectively separate and recover scandium metal ions, Sc(III), from an aqueous phase based on molecular recognition technology (MRT). Moreover, this approach is fully compatible with green chemistry principles. In this work, natural amorphous silica (SiO2) nanoparticles were prepared by a precipitation method from Iraqi rice husk (RH) followed by surface modification with 3-amino-propyl triethoxysilane (APTES) as coupling agent and Kryptofix 2.2.2 (K2.2.2) as polycyclic ligand. To evaluate the potential of the hybrid nanoparticles, the prepared HNPs were used for the solid–liquid extraction of scandium, Sc(III), ions from model solutions due to the fact that K2.2.2 are polycyclic molecules. These polycyclic molecules are able to encapsulate cations according to the corresponding cavity size with the ionic radius of metal by providing a higher protection due their cage-like structures. Moreover, the authors set the objectives to design a high-technology process using these HNPs and to develop a Sc recovery method from the aqueous model solution prior to employing it in industrial applications, e.g., for Sc recovery from red mud leachate. The concentrations of Sc model solutions were investigated using the UV-Vis spectrophotometer technique. Different characterization techniques were used including scanning electron microscope (SEM), atomic force microscopy (AFM), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier transform infrared (FTIR). The extraction efficiency of Sc varied from 81.3% to 96.7%. Moreover, the complexed Sc ions were efficiently recovered by HCl with 0.1 mol/L concentration. The stripping ratios of Sc obtained ranged from 93.1% to 97.8%.
