A review on preparation and characterization of silver/nickel oxide nanostructures and their applications

Nickel oxide and silver oxide nanoparticles have wonderful properties that could be employed in numerous applications. Thus, synthesis of nickel silver oxide nanostructures with different characteristics is of great interest. In this review, many synthesis methods were reported such as: electrodeposition, electrochemical method, simple immersion process and subsequent RFsputtering deposition, chemical oxidative polymerization, followed by acidic sol–gel process, flame-based process, liquidphase reduction technique, sol–gel, hydrothermal method, co-precipitation method, simple precipitation method, thermal decomposition, chemical wet synthesis, low and high-temperature reduction, high-pressure autoclave, thermal treatment method, and laser-liquid–solid interaction technique. Reporting all methods employed for the fabrication of NiO and Ag2O nanostructures is useful to produce and develop novel nanomaterials with enhanced properties and applications. Studying the factors that tuned their properties: particle size, shape, and capping agents as well as solution pH is highly recommended in future works. Also, further research studies should be conducted for finding another/other facile and effective synthesis method/methods

Binary nickel and silver oxides by thermal route: preparation and characterization

Many studies have concentrated on exploring behaviors of nickel silver oxide nanoparticles using various routes of fabrication. Thermal treatment technique has never been utilized to fabricate nickel oxide silver oxide nanoparticles. In this research, binary (NiO)0.4 (Ag2O)0.6 nanoparticles were synthesized using the thermal treatment method due to its attractive advantages such as low cost, eco-friendly, and purity of nanoparticles. The structural, morphological, and optical behaviors of these nanoparticles were investigated at different calcined temperatures. X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), ultraviolet–visible spectroscopy (UV–Vis), and photoluminescence (PL) were the techniques used to characterize the synthesized nanoparticles. XRD was conducted at different calcined temperatures. The crystallite size was increased from 25.4 nm to 37.0 nm as the calcined temperature increased from 500 °C to 800 °C. Also, TEM results verified that the mean particle size was enlarged as the calcined temperatures increased. Two band gaps were found for each temperature, which were decreased from (3.05, 2.45) to (2.70, 1.95) eV as the temperature varied from 500 to 800 °C, respectively. Broadbands were observed by PL spectra, and the intensity of two emission peaks was also increased at higher temperatures. The results approved the successful formation of binary (NiO)0.4 (Ag2O)0.6 nanoparticles by a novel facile synthesis route. These nanoparticles are likely to have various applications, especially optical applications due to the formation of two band gaps

THE IMPACT OF URANIUM NEAR A PHOSPHATE MINING PORT ON THE ENVIRONMENT (GULF OF AQABA, JORDAN)

Uranium has three isotopes in nature, the 238U, 235U and 234U. The presence of uranium isotopes in marine sediment at relatively high concentrations was the drivebehind several studies to determine the radionuclides levels in marine ecosystems to assess the potentially negative effects on environment. By using alpha spectroscopy, this study determined the activity concentrations of uranium isotopes in marine sediment and seagrasses from the northern Gulf of Aqaba in Jordan. Samples were collected from a phosphate mining port located at the northern coastline Gulf of Aqaba in Jordan. In marine sediment of the phosphate port, the activity concentrations of alpha emitters were (783.47 - 836.17, 29.43 - 30.43, and 804.56 - 847.80 Bq kg -1) for 238U, 235U and234U, respectively, and (158.19 Bq kg -1) in seagrasses samples. Our results show that the determined levels of uranium radioactive isotopes are more than the internationally accepted limit byapproximately two folds. In conclusion, raw phosphate dusts might be one of the main pollution sources for marine ecosystems in the Gulf of Aqaba

EFFECTS OF TOXIC ELEMENTS ON LEAF MORPHOLOGY OF HALOPHILA STIPULACEA GROWINMINE DUMP SEDIMENTS IN SOUTHEAST JORDAN

Plants, in particular seagrasses, that grow in contaminated areas can uptake and accumulate Potential Toxic Elements (PTEs) in their tissues. This accumulation in turn can produce several effects on plant morphology and health status. This study, carried out on seagrass (Halophila stipulacea) growing on the phosphate mine dump sediments in southeast Jordan, highlights the possible leaf damages at anatomical and cytological levels. The micro-morphological observationsdemonstrated that the damage caused by PTEs was easily found throughout the leaf, showing massive change in the overall organization of cells, both in theepidermis and the mesophyll and vascular bundles. This probably caused the blockage of liquids and nutrients, leading to necrosis of the leaf in comparison to the control. Moreover, seagrass samples collected from phosphate port area showed a swelling in the outer epidermal wall, and in some cases a collapse in parenchyma was observed. In addition, collapse in the epidermis, chloroplasts degradation, and necrosis of some cells was detected. The observed morphological change seems to be correlated to contamination levels in the sediments

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
