The highest luminescence product consists of spheroidal and relatively uniform particles with sizes around 0.6-1.0 µm. The variation of the precipitated precursor with temperature, the influence of sintering temperature on structure and luminescence, the mineralization role of boric acid and the chemical reactions that occur with generation of precipitated precursors and upon heating to give luminescent solid solution products are mentioned.

In this paper, we discuss the efficiency of using a Fe2V4O13 catalyst in a heterogeneous Fenton-like process for the degradation and mineralization of Ind. We examined various factors that influence the reaction, such as the initial pH of the reaction mixture, the initial concentration of hydrogen peroxide, the amount of the Fe2V4O13 catalyst, and the reaction temperature was investigated.

The experiment was conducted to study the effect of different air pollution (ozone O3, sulfur dioxide SO2, and nitrogen dioxide NO2 gases) on Eruca sativa Mill. at three locations in Riyadh city, KSA. During the study, we found that the concentrations of gases were increasing gradually at the study sites.

In this work, the influences of boric acid and high alumina cement used as modifying additives on the formation of CaO∙Al2O3 and CaO∙2Al2O3 were studied. Herein, commercially available chalk of the M-90 label and technical alumina of the G-0 label were utilized as initial raw materials. Heat treatment of powder mixtures with various concentrations of modifying additives was carried out in the temperature range of 1250-1350oC with an isothermal exposure times of 1h and 2h.

The purpose of this project is to enable the prediction of flow behaviour of concentrated slurries in the pipe loop under various laminar flow conditions using the fluid analogue to slurry and to find the suitable rheological model from the literature for the fluid analogue and tailings from the Sunrise dam. The major objective of the project is to develop a fluid analogue which will have similar rheological behaviour to that of the tailings from Sunrise dam so that it can be used as a test material to predict the flow behaviour of tailings in a pipe.

The results showed that SOM content was higher in horizon A, whereas mineral matrix elements Al, Fe, and Mg contents were higher in horizon B. Ca and P contents gradually decreased with soil depth due to the influence of fertilizer. Three types of trace element concentration profiles were identified: (1) decrease with depth for Cd and Hg

Mineral selenium (Se) is an essential nutrient of great importance to biology of human. Cultivation of Saccharomyces cerevisiae cells in molasses medium with different concentrations of selenium showed that the contents of organic selenium in the cells, increased with the increase in selenium concentration up to 2 lg/ml followed by a gradual decrease after 24 h of incubation.

Liquid–liquid extraction of Au(III) from aqueous sodium malonate medium using 2-octylaminopyridine (2-OAP) as an extractant in xylene was achieved. The current work explored the influence of several experimental parameters such as pH, weak acid concentration, extractant concentration, equilibrium time, stripping agents, and aqueous:organic volume ratio on the extraction of Au(III). The experimental results showed that the Au(III) was quantitatively extracted to about 99.5% by 0.05 M 2-OAP in 0.05 M malonate at 5.0 pH.

Solvent extraction of molybdenum from various acid media by Alamine 336, Aliquat 336, TOPO, and DEHPA in kerosene was studied. The extraction efficiency of molybdenum by diisobutyl ketone (DIBK), the effects of various parameters like diluents, mineral acids, extractant concentration, and applications of these extractants on molybdenum extraction contained in the uranium-bearing ore solutions were investigated. DIBK used as solvent can indeed extract the molybdenum without adding any extractants in the range of 20–50 mg/L.

In this paper, the protective role of melatonin in counteracting metal-induced free radical generation was highlighted. Using the HPLC-FLD technique melatonin was identified and quantified in the roots and leaves of lemon balm (Melissa officinalis L.), grown under photoperiod conditions. Furthermore, the response of plants pre-treated with exogenous 0.1 mM melatonin to the increased zinc (Zn) and cadmium (Cd) concentrations was observed, with changes in mineral (Ca, Mg), physiological and antioxidant status of the plant during heavy metals stress.
