New High Entropy Alloys based on the CoCrFe2Ni2 system have been developed by adding up to 10 at. % of Cu, Mo, and Cu + Mo in different amounts. These alloys showed a single face-centred cubic (FCC) structure after homogenization at 1200 °C. In order evaluate their thermal stability, aging heat treatments 500, 700, 900 °C for 8 h were applied study possible precipitation phenomena. where only o...

The first-row transition metals (TMs) are applied to induce the assembly of small molybdenum clusters (SMCs) in the molybdenum/TM/phosphate system, and eight SMC-based compounds are synthesized: [(V(2)O(2))(H(2)PMo(8)V(4)O(40))]·2(en)·12H(2)O (1), [CrMo(6)O(18)(OH)(6)]·1.5(H(2)en)·5H(2)O (2), [MnMo(12)O(24)(OH)(6)(HPO(4))(2)(PO(4))(6)]·7(H(2)en)·6H(2)O (3), {[Co(H(2)O)](2)[CoMo(12)O(24)(OH)(6)(...

The liver plays a major role in regulating glucose metabolism, and since its function is influenced by sympathetic/ parasympathetic innervation, we used liver graft as a model of denervation to study the role of CNS in modulating hepatic glucose metabolism in humans. 22 liver transplant subjects were randomly studied by means of the hyperglycemic/ hyperinsulinemic (study 1), hyperglycemic/isoin...

Introduction: In recent years, attraction toward drinking bottled mineral water has increased. Therefore, chemical composition and safety of these waters considering trace elements and heavy metals should confirm the national or international standard limits. The aim of this study was to evaluate and comparison of the mineral and heavy metal composition of bottled waters in Bandar Abbas with Ir...

Abstract The Huayangchuan ore belt is located in the western segment of Xiaoqinling Orogen southern margin North China Craton (NCC), and hosts voluminous magmatism significant U?REE?Mo?Cu?Fe polymetallic mineralization. However, geochronological framework various mineralization phases this region poorly understood. Here, we present new Re?Os isochron ages on magnetite from Caotan Fe deposit (2 ...

Polycrystalline CuInS(2) films were fabricated by sulfurization of electrodeposited Cu and In metallic precursor films in a Cu-rich composition at 520 °C in H(2)S (5% in Ar). Structural analyses revealed that the adherence of the thus-formed CuInS(2) film to the Mo substrate was strongly dependent on heating profiles of the Cu/In bilayer film: a CuInS(2) film with poor adherence having many cre...

In this work, the concentrations of the potentially toxic elements in stream sediments in SE Nigeria were assessed for pollution monitoring in mining, quarrying, and farming areas. The levels of iron, molybdenum, vanadium, copper, lead, zinc, nickel, cobalt, manganese, chromium, barium, and beryllium were determined. The concentrations of the elements were in the order of Fe > Ba > Mn > Cr > Zn...

Few studies have been reported on alterations of trace elements (TE) in peritoneal dialysis patients. Our objective was to investigate and assess the characteristics of daily TE excretions in continuous ambulatory peritoneal dialysis (CAPD) patients. This cross-sectional study included 61 CAPD patients (nonanuric/anuric: 45/16) and 11 healthy subjects in Wuhan, China between 2013 and 2014. The ...

A study was conducted evaluating the effect of long-term Cu deficiency, with or without high Mn, on growth, gene expression and Cu status of beef cattle. Twenty-one Angus calves were born to cows receiving one of the following treatments: (1) 10 mg supplemental Cu/kg DM (+Cu); (2) no supplemental Cu and 2 mg Mo/kg DM ( - Cu); (3) - Cu diet plus 500 mg supplemental Mn/kg DM ( - Cu+Mn). Calves we...
