The clay-hosted lithium deposit in Sonora, Mexico, represents a potential mining site for this critical mineral, which is essential for clean energy technologies and currently in high demand during the energy transition....

The study deals with determining the concentrations of heavy metals—silver (Ag), aluminum (Al), arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), lithium (Li), manganese (Mn),...

ABSTRACT The biological study was conducted at the University of Mosul, College of Education, Department of Biology. To aims at identifying effects of environmental pollution in the seven sites at Nineveh (Al-Rahmanyah,...

Abstract An external electric or magnetic field can transfer high-intensity energy directly to the electronic scale of materials, and change the spin, energy level arrangement and trajectory of electrons. These changes p...

The present study involves an assessment of pollution through the impact of heavy metals in the waters of the 17 July estuaries, the Industrial zone on the left, Muthanna coasts, and the Nineveh Bridge of the Tigris Rive...

Abstract In this study Three genera of common algae isolated from local environment in Mosul city were tested for their ability to utilize heavy metals Oscillatoria angustissima, Fragellaria vaucheria and Lyngbya tylorii...

Abstract Background Epidemiological associations between multiple metals exposure and hypertension or blood pressure remain limited and inconclusive, especially for essential metals. This investigation intended to examin...

Chemical dissolution processes coupled to anodic oxide growth taking place by a "high-field" conduction mechanism, are considered. The equation for the steady-state current density obtained during potentiodynamic polariz...

Objective To explore the association between trace metals and multiple health outcomes. Methods The cross-sectional study was from eight cycles of National Health and Nutrition Examination Survey (NHANES) from 2005 to 20...

We investigate the electronic transport at the internal interface within a selection of metallic bilayer nanostructures using the contact-free, all-optical method of THz time-domain spectroscopy. The Ru/Co, Ru/Pt, and Ru...

A survey of the elemental contents of K, Mg, Mn, Na, Cl, Br, Cs, Co, Rb, Fe, Zn, Al, Ti, V, As, Ag, Au and Cd in liver, kidney and muscle was performed in specimens of Commerson's dolphins (Cephalorhynchus c. commersonii...

The target of this research is removing transition metals of Cr, Mn, Fe, Zn, W, Cd from soil due to nanomaterial-based gallium nitride nanocage (B5N10-nc). The electromagnetic and thermodynamic attributes of toxic transi...

In this work, a quantitative analysis of heavy metals Cr and Cu in fluvial sediments was carried out by Laser-induced breakdown Spectroscopy (LIBS) to assess the anthropogenic. To perform the analysis, different sediment...

Abstract: To investigate the interaction of heterogeneous solutes in the common molten pool flow during laser welding of heat-resistant steel and nickel-based alloy, a multiphase flow coupled welding model was establishe...

In the present study we have measured the electrical conductivity of Mn(II), Ni(II), Fe(II) complexes with Arginine in aqueous solutions of mono and di saccharide at (310.16 K), The data were analyzed using Lee-Wheaton(L...

The preparation of series of complex chloride of the type R2[M"C14] or R2[M"'C16], when R = M" = Mn, Co, Ni, Cu , Zn, M'" = Fe, and Cr has been carried out. The conductivity, IR, Uv-visible spectra, magnetic susceptibi...

We present ab initio quantum-mechanical molecular-dynamics calculations based on the calculation of the electronic ground state and of the Hellmann-Feynman forces in the local-density approximation at each molecular-dyna...

The optical constants $n$ and $k$ were obtained for the noble metals (copper, silver, and gold) from reflection and transmission measurements on vacuum-evaporated thin films at room temperature, in the spectral range 0.5...
