“…On the other hand, the vibrational modes of the PO 4 −3 group located at 601, 628, 1041, 1085, and 3757 cm −1 are developed with the HAP loading. The obtained IR band positions are matched with data reported by different research groups [ 37 , 38 ]. The IR data confirms the formation of HAP@MgO composites in a pure state without the presence of any other compound(s).…”

Micro-carriers are the best known vehicles to transport different kinds of drugs to achieve high impact. In this study, mesoporous magnesium oxide has been harnessed as a micro-carrier to encapsulate the anticancer candidate drug natural-based cubic hydroxyapatite (HAP). HAP@MgO composites with different HAP loading (0–60 wt %), were prepared by a hydrothermal treatment method using triethanol amine as a template. The characterization of the prepared composites were achieved by using XRD, Raman spectroscopy, FTIR and SEM. Characterization data confirm the formation of sphere-like structures of MgO containing HAP particles. It was observed that the size of the spheres increased with HAP loading up to 40 wt %, then collapsed. Furthermore, the anticancer property of the prepared composites was evaluated against the HepG2 liver cancer cell line. The HAP@MgO composites exhibited higher activity than neat MgO or HAP. The 20 wt % of HAP was the optimum loading to control cell proliferation by inducing apoptosis. Apoptosis was determined by typical apoptotic bodies produced by the cell membrane.

“…This pattern showed that a single cubic phase was consistent with the standard spectrum of cubic MgO (JCPDS card no: 45-0946) (51). The specific surface area of MgO nanoparticles was measured using the BET equation applied to the adsorption data (52). The results showed that the average specific surface area of MgO nanoparticles was 102.6 m 2 /g.…”

This study investigated the effect of various parameters on the removal of Reactive Blue 203 dye from wastewater using ferrate(VI) oxidation process, ultraviolet radiation (UV) radiation and MgO nanoparticles under batch mode. Although several studies have been carried out on dye removal, there is no study on the removal of Reactive Blue 203 dye using ferrate(VI) oxidation process, UV radiation, and MgO nanoparticles. Therefore, the aim of this study is to investigate the effect of different factors including pH, temperature, contact time, the intensity of UV radiation and the concentration of MgO nanoparticles on Reactive Blue 203 dye removal using the above-mentioned methods. The results showed that the best pH values for dye removal using UV radiation, ferrate(VI), and MgO nanoparticles were 13, 1 and 13, respectively. The best temperature for Reactive Blue 203 dye removal using ferrate(VI) was 50°C. Hence, temperature variation had no significant effect on Reactive Blue 203 dye removal using UV irradiation and absorption by MgO nanoparticles. Based on the results, the best contact time was 15 minutes using UV radiation. The removal of Reactive Blue 203 dye using ferrate(VI) oxidation process was a quick reaction, and in a fraction of a second, the reactions were completed. The results showed that dye removal using MgO nanoparticles could be described by the Temkin isotherm. Therefore, the contact time was not considered as an effective parameter. In addition, the maximum dye removals were 95, 85 and 94% using UV irradiation, ferrate(VI) and MgO nanoparticles.

“…[29] The bands that appeared at low frequencies of 836 and 652 cm −1 correspond to stretching vibrations of Mg O Mg bonding. [30] The peak at 600 cm −1 is may be due to characteristic vibration of Ca O and bands near 836,652 cm −1 are may be due to vibrations of Mg O Mg bonding in WNS ash.…”

This paper reports walnut shell ash (WNS ash) a sustainable material for tubeless inner liner application. This sustainable material replaced the commercial magnesium oxide (MgO).The WNS ash generated at 550 C, is found to have 72% alkali metal and alkali earth metal, whereas commercial MgO shows 95% alkali metal and alkali earth metal. It was observed in this study WNS ash perform as cure retarder in bromobutyl rubber/bromo isobutylene isoprene rubber-based tube less inner liner compound and its performance was similar with commercial MgO; however, not exactly equivalent. Optimum cure retardation found at 0.40 phr loading with WNS ash. Interestingly, due to sulfur (S) and zinc (Zn), the WNS ash produced some cure activation effect. Cure rate was observed for 0.40 phr WNS ash load in gum/filled formulations at 35/15 minutes −1 compared to 30/10 minutes −1 in commercial MgO at 0.30 phr. Physical properties of compound made with 0.40 phr WNS ash and 0.30 phr MgO found comparable in both gum and filled system. Alkali metal and alkali earth metal of WNS ash at 0.40 phr loading is equivalent to 0.30 phr of MgO. This material is an important gateway in the rubber industry as a multifunction sustainable material.
