Although some studies suggested a link between exposure to trace elements and development of multiple sclerosis (MS), clear information on their role in the aetiology of MS is still lacking. In this study the concentrations of Al, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Mn, Mo, Ni, Pb, Sb, Si, Sn, Sr, Tl, V, W, Zn and Zr were determined in the blood of 60 patients with MS and 60 control...

With the growth of automobile, machinery, and aerospace industries, demand for high-performance surface coatings having multifunctional characteristics use in mechanical parts is increasing. In this study, ternary/quaternary Mo–Cu–Cr–(N) nanocomposite were deposited at different N2 gas flow rates using direct current magnetron sputtering from a multicomponent single-alloy target. The target sim...

The clinical significance of an elevated cations. None were fatal, and all occurred platelet count in the course of chronic in the group with counts over a 1 x 1 0’/cu granulocytic leukemia was studied in a mm. The occurrence of thrombocytosis as group of 111 previously untreated paa new observation in the face of previous tients, whose entire course was evaluated normal counts (15 patients) wa...

Engineered metal oxide nanoparticles (MO NPs) are finding increasing utility in the medical field as anticancer agents. Before validation of in vivo anticancer efficacy can occur, a better understanding of whole-animal toxicity is required. We compared the toxicity of seven widely used semiconductor MO NPs made from zinc oxide (ZnO), titanium dioxide, cerium dioxide and tin dioxide prepared in ...

The equiatomic CoCrFeMnNi alloy and the quaternary alloys with no addition of one element were fabricated, roles alloying elements in corrosion resistance clarified. In 1 M H2SO4, passivity was mainly due to Cr. Co Fe additions also contributed decrease current density. While Ni found suppress active dissolution, Mn increased dissolution rate. without indicated superior pitting 0.1 NaCl. To imp...

Polymetallic Indian Ocean nodules offer a lucrative resource for valuable strategic metals such as Cu, Co and Ni. A novel bioleaching process using cell-free spent growth medium from a fully-grown culture of a marine organism isolated from the nodules (Bacillus M1) dissolved about 45% Co, and 25% Cu and Ni at a the pH of 8.2 in 4 h. To enhance metal dissolution, different modifications in the b...

The neutral hydrogen evolution reaction (HER) is vital in the chemical industry, and its efficiency depends on interior character of catalyst. Herein, work function ( W F ) engineering introduced via 3 d metal (Fe, Co, Ni, Cu) doping for modulating Fermi energy level Mo 2 C. defective facilitates free water molecule adsorption and, subsequently, promotes HER efficiency. Specifically, at a curre...

Most micro-electro-mechanical systems (MEMS) devices contain fragile moving parts, which poses challenges in process integration of interconnection methods requiring wet-chemistry, such as solid-liquid interdiffusion bonding (SLID). These sensitive MEMS structures can be protected from either the wet-chemistry or plated metals during chemical/electro-chemical plating SLID materials; however, th...
