“…This peak is sharp well which indicates the formation of pure phase particles. The residual hydroxyl groups further supported by the presence of absorbance bands in the region of ~1600 cm -1 and ~800 cm -1 [9,22]. The strong broad band at 1471 cm -1 and a peak at 876 cm -1 indicate the C-O bond arose because of the carbonation of CaO nanoparticles [9].…”

“…The small variation in the value of lattice constant and d-spacing from that of the bulk value is attributed to the presence of microstrain and defects that occurred during the growth process. These microstrain and dislocation densities have been determined (Table 1) using the relation given by Dhupar et al [22] with an average value of 2.764×10 -3 and 6.32×10 -15 line/m 2 respectively.…”

“…CaO and Ca(OH) 2 nanoparticles are reported to synthesized by sol-gel method, thermal decomposition, precipitation, hydrothermal, microwave-assisted method, etc., [3,9,[11][12][13][14][15][16][17][18][19]. Among all these methods, direct precipitation is simple, cost-effective, reproductive and rapid technique for nanoparticles synthesis [20][21][22]. Therefore, in this work direct precipitation technique was used to synthesize CaO nanoparticles and characterize them using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field effect scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS) and diffuse reflectance spectroscopy for different properties.…”

Calcium oxide (CaO) is a promising material that works as a glass constituent, catalyst, toxicwaste remediation, poisonous gas absorbent, industrial refectory element for metal smelting, paper bleaching, sulfur neutralization in sugar, cosmetics and drug delivery mediator. This work proposes the synthesis of CaO nanoparticles by direct precipitation technique using an aqueous solution of calcium chloride and sodium hydroxide precursors. The synthesized nanoparticles are characterized for the structure, morphology, chemical composition and optical behavior using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field effect scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), and diffuse reflectance spectroscopy. The XRD results show that the CaO nanoparticles have been synthesized in a cubic crystalline structure with the average crystallite size of about 13 nm and display aggregated morphology of nanoclusters. The presence of distinct peaks in the FTIR and EDS spectra reveal that the nanoparticles are successfully formed from the chemical recipe of the precipitation process. The optical bandgap has been estimated from the Kubelka-Munk plot and found to be 3.48 eV. The antibacterial activity of CaO nanoparticles has been tested by the well diffusion technique and observed that it shows good antibacterial action against the gram-negative bacterial strains.

“…As exhibited in Figure 1d,e, the adsorption signals located at 646 and 749 cm −1 are observed on Zn sheets soaked in DASS/H 2 O solution, which can be related to the vibrations of Zn─N bond. [ 33 ] Additionally, another set of peaks of 845 and 1044 cm −1 are corresponded to the Zn─S bond, [ 34 ] further demonstrating the interfacial coordination. And the Raman spectra of Zn sheet immersed in DASS/H 2 Osolution also delivers the Zn─S bonds at 257, 785, and 1129 cm −1 , as well as the Zn─N bond at 423 cm −1 (Figure 1f).…”

The long‐term reversible plating/stripping of Zn metal anode is a critical aspect within aqueous zinc‐ion batteries (ZIBs). However, it is limited by uncontrolled electrodeposition and side reactions occurring at the anode/electrolyte interface. Guided by the metal‐coordination chemistry, a novel additive, sodium diphenylamine sulfonate (DASS), is added into ZnSO4 electrolyte to guide stably invertible zinc deposition. Theoretical calculations and experimental results reveal that the DASS can adsorbed on the Zn anode surface due to the strong double coordination effect between N, S sites and Zn (Zn─N, Zn─S), and this adsorbed DASS layer can not only prevent the intimate contact between H2O and anode to inhibit interfacial side reactions, but also guide the 3D Zn2+ion diffusion and uniform electrodeposition to inhibit zinc dendrites. Consequently, the DASS additive enables an ultra‐long stable cycling up to 2400 h at 1 mA cm−2 (1 mAh cm−2), even at an ultra‐high current density of 20 mA cm−2, a stable cycling of 250 h is demonstrated, highlighting the reliable coordination effect at the anode/electrolyte interface. This study offers a new perspective on the interfacial double‐coordination effect for achieving highly reversible Zn metal anodes in aqueous rechargeable zinc‐ion batteries.

As a result of increasingly rigorous environmental legislation and industry adoption of waste minimization recommendations, the development of recycling and reuse possibilities for metal-related trash has become increasingly important.Inthis research, calcium oxide and mixture of calcium, iron, and magnesium oxides was extracted from the wastes of cement factories using hydrofluoric acid. As a result, this research provides a comprehensive picture of waste recycling, and reuse throughout extraction and it examines the current state and potential developments in mineral and metal waste recycling and reusing them in different applications, among these applications, it is used CaO and CaO:MgO:Fe 2 O 3 NPs in medical applications, including uterine cancer. Characterizations of the extracted nano-products were done using (XRD) which confirmed the crystalline nature of CaO and the mixture of CaO:MgO:Fe 2 O 3 NPs. More, (FESEM) has been used to demonstrate the morphology of the nanostructures of CaO and the mixture CaO:MgO:Fe 2 O 3 NPs. The data yielded the average grain size of CaO and the mixture CaO:MgO:Fe 2 O 3 NPs calculated by SEM and XRD (64.08, 84.2) nm and (38.636, 31.597) nm respectively. (EDS) spectrum and XRD pattern suggested that prepared CaO and the mixed CaO:MgO:Fe 2 O 3 NPs were highly pure. In addition, the ability of NPs as a promising anticancer agent was tested against MES-SA cells line, according to the MTT assay results of MES-SA cells the I C50 (91.65 and 98.4) μg/mL for CaO and CaO:MgO:Fe 2 O 3 NPs respectively. The results showed that the extracted nanoparticles CaO and the mixture CaO:MgO:Fe 2 O 3 NPs served as an anticancer agent.
