“…The result also show peak at 2theta 18.3°was identified higher than the control sample. This could indicate an overlapping peak that possibly as a result of starch and sodium interaction and also additional peaks originating from sodium hydrogen carbonate [23]. Since the main peaks in XRD diffractogram considered low compared to the additional peaks, which indicated the amorphous results, then our study confirmed the starch and sodium combination using FTIR characterization.…”

“…The treatment with NaOH detected the change of glutinous rice flour crystalline conformation, which promoted not only main peaks of the glutinous rice flour but also identified additional peak formation originating from sodium hydrogen carbonate. These additional peaks could be detected overlapping at 2theta 18.3°and also strong peak at 2theta 27.7°, 29°, and 34.6° [23]. In comparison to the control sample (21.51%), the relative crystallinity of samples A-D decreased to 10.03%, 7.52%, 9.89%, and 9.24%, respectively.…”

In this work, nanorod particles were synthesized from a locally available source, glutinous rice flour, using sodium hydroxide (NaOH) through a simple precipitation process. The synthesized nanofillers were then presented as an alternative organic filler for dental impression application to support the making of a diagnostic and working model. Dynamic Light Scattering, Scanning Electron Microscope, Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Energy Dispersive Spectroscopy, Thermogravimetric Analysis, and Differential Scanning Colorimeter were used to characterize the fillers. The particle size measurement, morphology interaction, and composition of glutinous rice flour nanorod particles were also investigated. The cell viability using 3T3L1 cells was assessed to determine the safety of nanorod particles using the MTT assay and trypan blue solution. All treated samples exhibit a change in particle morphology from polyhedral to rod. We observed a decrease in crystallinity, dehydration, and gelatinization temperature. Its functional group interacting with sodium hydroxide also changes slightly after size reduction. The samples treated with 3000 centrifugation speed without surfactant addition showed changes from the control sample's 3931.71 nm to the smallest average width particle size of 73.26 nm with an average length of 865.15 nm. All of the treated samples with NaOH and NaOH-surfactant additions met the non-cytotoxicity acceptance criteria in the range of 73.54-99.58%, according to the cell viability results. The incorporation of 15 wt% of the synthesized nanorod fillers resulted in a 20 µm continuous line as the impression materials specimen, yielding a satisfactory detail reproduction test result. In conclusion, nanorod particles with biocompatible properties have been successfully manufactured and can potentially be used in the future as an alternative dental impression filler materials.

“…The activities of 0.6 %-Ni/TiO 2 and 2 %-Ni/TiO 2 were up to 54.0 mol Na2CO3 mol Ni À 1 h À 1 and 50.0 mol Na2CO3 mol Ni À 1 h À 1 , respectively, which are higher than other non-noble metal catalysts in carbonate hydrogenation reported in the literature (Tables S5 and S6). [9,11,22,24,[27][28] As is shown in Figure 1d, the catalytic activity of 2 %-Ni/TiO 2 was well maintained after five cycles of reaction, suggesting the good stability and reusability of the catalyst. In order to explore the effect of H 2 , the catalytic performance of 2 %-Ni/TiO 2 under different H 2 pressures was tested (Table S7).…”

Carbonate hydrogenation to formate is a promising route to utilize captured carbon dioxide into valuable chemicals, thus reducing carbon emissions and creating a revenue return. Developing inexpensive catalysts with high activity, selectivity, and stability remains challenging. We report a supported non‐noble metal catalyst, Ni/TiO2, with great selectivity over 96% and excellent stability in catalyzing the conversion of carbonate into formate in aqueous solution. Ni0 and Ni2+ species are both observed in Ni/TiO2 catalysts, and the synergistic effect of these two Ni components leads to high activity and high selectivity of carbonate hydrogenation to formate.

“…Heavy metals, organic pollutants, inorganic anions and bacteria have been reported to be successfully removed by various kinds of nanomaterials 21 . Recently, research on Nickel Ferrite Nanoparticles (NFNs) have attained considerable attention 22 because of the difference of their physical and chemical properties from those of the free atoms or molecules 8,16,23 as well as from the properties of the bulk solids and have wide range of potential applications. Due to its typical ferromagnetic properties, low conductivity, lower eddy current losses and high electrochemical stability.…”

“…This paper aims to report the synthesis of Nickel Ferrite Nanoparticles (NiFe 2 O 4 ) by using co-precipitation method. The potential use of these nanoparticles as adsorbent 22 for removal of heavy metals (Cr(VI), Pb(II) and Cd(II)) from synthetic wastewater was investigated particularly 25 . For this purpose, the influence of pH, contact time and initial does on the sorption capacity of NFNs has been studied.…”

The heavy metals, such as Cr(VI), Pb(II) and Cd(II), in aqueous solutions are toxic even at trace levels and have caused adverse health impacts on human beings. Hence the removal of these heavy metals from the aqueous environment is important to protect biodiversity, hydrosphere ecosystems, and human beings. In this study, magnetic Nickel-Ferrite Nanoparticles (NFNs) were synthesized by co-precipitation method and characterized using X-Ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Field Emission Scanning Electronic Microscopy (FE-SEM) techniques in order to confirm the crystalline structure, composition and morphology of the NFN’s, these were then used as adsorbent for the removal of Cr(VI), Pb(II) and Cd(II) from wastewater. The adsorption parameters under study were pH, dose and contact time. The values for optimum removal through batch-adsorption were investigated at different parameters (pH 3–7, dose: 10, 20, 30, 40 and 50 mg and contact time: 30, 60, 90, and 120 min). Removal efficiencies of Cr(VI), Pb(II) and Cd(II) were obtained 89%, 79% and 87% respectively under optimal conditions. It was found that the kinetics followed the pseudo second order model for the removal of heavy metals using Nickel ferrite nanoparticles.
