“…Despite the differences in TiO 2 content between samples taken for the XRF and ICP-OES analyses, both methods were able to confirm that TiO 2 NPs can penetrate through seed coats and interact with seeds. Discrepancies between XRF and ICP-OES values have also been reported by other researchers [54,55]. The content of TiO 2 NPs_CE determined by XRF was higher than the values determined by ICP-OES; this is perhaps due to the fact that XRF is a non-destructive method that allows the direct measurement and avoids the loss associated with sample pre-treatment, thus avoiding leakages.…”

Seed priming is a novel approach that is undertaken to improve seed germination and therefore potentially enhance growth and yield. Low-cost, eco-friendly, and efficient seed treatment as a means of enhancing growth and yield is still being sought for high-value crops such as pomegranates (Punica granatum L.), particularly in areas situated at high altitudes such as the Taif region. The uptake of nanoparticles (NPs) by plants provides a potential pathway for NP exposure. Therefore, it is imperative to understand NP uptake via seed priming and their unique properties within plants. In the present study, titanium dioxide nanoparticles (TiO2NPs) were green-synthesized and utilized as priming agents for pomegranate seeds at a concentration of 40 mg/mL for 24 h. The adsorption of NPs was verified by scanning electron microscopy (SEM) and energy dispersive X-ray analysis/spectroscopy (EDX), while their incorporation was detected by transmission electron microscopy (TEM). To validate the EM results, X-ray fluorescence (XRF) and inductively coupled plasma optical emission spectroscopy (ICP–OES) techniques were further undertaken. The results confirmed the successful synthesis of pure anatase TiO2NPs by employing aqueous extracts of pomegranate fruit peel (PPE) and coffee ground beans (CE). All of the analytical techniques employed in this research confirmed the incorporation of TiO2NPs inside seeds, even after storage during priming treatment. This study lays the foundation for future sustainable seed technologies in terms of crop productivity and seed germination.

“…The comparison in Figure 7 reveals that the ICP-OES may be more sensitive and can detect more elements at low concentrations, while the element concentrations from the XRF are mostly greater than those from the ICP-OES for elements present in higher concentrations. Lower LoDs for ICP-OES compared to XRF have been reported elsewhere (McComb et al, 2014;Chojnacka et al, 2018). The differences may come from the principles of the analytical methods.…”

Detailed characterization of physical and fuel properties of construction and demolition waste (CDW) can support research and commercial efforts to develop sustainable aviation fuels. The current study reports time-series data for bulk density, mineral composition, reactivity, and fuel properties (proximate analysis, ultimate analysis, heating value and ash fusibility) of the combustible material fraction of samples mined from an active CDW landfill on the island of Oʻahu, Hawaiʻi. The fuel properties are in ranges comparable to other reference solid wastes such as demolition wood, municipal solid wastes, and landfilled materials. Ash fusion temperatures (from initial deformation to fluid deformation) among the samples were found to lie in a narrow range from 1,117 to 1,247°C. Despite higher ash contents, the CDW derived feedstock samples had comparable heating values to reference biomass and construction wood samples, indicating the presence of higher energy content materials (e.g., plastics, roofing material, etc.) in addition to wood. The waste samples show lower reactivity peaks in the devolatilization stage, but higher reactivity peaks (located at lower temperatures) in the gasification and combustion stage, compared with those of reference biomass and construction woods. Mineral elemental analysis revealed that materials from various sources (gypsum, plastic, rust, paint, paint additives, and soils) were present in the samples. Soil recovered from the landfill contained higher Ca, Cu, Fe, K, Mn, Pb, and Zn levels than soil samples from elsewhere on the island. Results from this study can provide insight on variations in the physical and fuel properties of the CDW derived feedstocks, and support the design of conversion systems.

The biosorptive potentials of three aquatics-based biosorbents, including shells of a bivalve mollusk and scales of two fish species for Pb removal from aqueous solutions were evaluated, for the first time. A Box–Behnken design with the response surface methodology was used to investigate the effects of the seven important variables (contact time, temperature, initial concentration, dosage, size, salinity and pH) on the sorption capacity of the sorbents. Among the seven studied factors, the effects of biosorbent dosage, initial concentration and pH were significant for all the response variables, while biosorbent size was not significant for any of the responses. The initial concentration was the most influential factor. The presence of Pb ions on the surfaces of the biosorbents after the adsorption was clearly confirmed by the SEM–EDX and XRF analyses. The maximum sorption capacities of the biosorbents were comparable to the literature and the descending order was as follows: scales of Rutilus kutum and Oncorhynchus mykiss and the shells of Cerastoderma glaucum. The isotherm studies revealed Langmuir model applicability for the Pb adsorption by R. kutum and O. mykiss scales, while Freundlich model was fitted to the adsorption C. glaucum shells.
