The demand for responsibly sourced cobalt has increased dramatically as a result of the global transition to ‘fossil-free’ electromobility. However, distribution, mineralogical expressions and mechanisms concentration Co in different types hydrothermal ore deposits remain poorly constrained, inhibiting resource assessments exploration. Here we report other metal concentrations ores from active ...

Ten cadmium resistant marine bacterial isolates were isolated from seawater and sediments samples of Hurghada harbour on a seawater nutrient agar medium amended by 25 ppm of cadmium and tested for their resistance to higher cadmium concentrations (up to 200 ppm). The most resistant isolate which was able to grow at 150 ppm was identified on the basis of its morphological, physiological and bioc...

The presence of high level of heavy metals involves a human healthy risk that could induce chronic diseases. This work reports on the metal contamination due to heaps of steel-slag accumulated during more than 40 years in allotments and industrial areas in the southern part of Madrid (Spain). Several slag and soil samples were collected in an area of 10 km(2) and characterized by different conv...

Erythropoietic protoporphyria (EPP) is an autosomal inherited disease of heme biosynthesis caused by a partial deficiency of the enzyme ferrochelatase. Patients with EPP show only 20–30% normal activity because of mutations in one of the alleles of the ferrochelatase gene. To clarify the molecular mechanisms of this low level of activity, we co-expressed human ferrochelatase carrying Hisand HA-...

Murrell and Burnett (M-B) ( 1982) reported that oldhamite (CaS) is the primary host phase ofU and Th in the E6 chondrites. E-chondrite Th/U values were all cosmic, indicating a lack of Th-U fractionation in both oldhamite and in the bulk meteorites. In Khairpur (E6), they attributed excess fossil fission tracks to the presence of Pu in oldhamite. Rare earth (REE) enrichments were inferred for a...

Abstract Gallium (Ga) and germanium (Ge) are technologically important critical elements. Lead blast furnace slags from Tsumeb, Namibia, comprise over two million metric tons of material that contains high levels Ga (135–156 ppm) Ge (128–441 in addition to significant Zn concentrations (up 11 wt.%) represent a potential resource for these A combination mineralogical chemical methods (PXRD, FEG-...

the types of scion-rootstock compound and level of salinity affect on growth characteristics and concentration of nutrition elements of almond leaves and roots. in order to evaluate the effect of salinity stress on vegetative traits and concentration of nutrition elements of leaves and roots almond genotypes, a experiment was carried out with two factors; cultivar in four levels including ‘shah...

The morphology of SnO2 nanospheres was transformed into ultrathin nanosheets assembled architectures after Zn doping by one-step hydrothermal route. The as-prepared samples were characterized in detail by various analytical techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and nitrogen adsorption-desorption technique. The Z...
