The title compound, (sodium magnesium) [magnesium iron(III) silicon] disilicate, (Na(0.97)Mg(0.03))(Mg(0.43)Fe(0.17) (3+)Si(0.40))Si(2)O(6), is isotypic with ordered P2/n omphacite. Its structure is characterized by single chains of corner-sharing SiO(4) tetra-hedra, extending along the c axis, which are crosslinked by bands of edge-sharing octa-hedra (site symmetry 2), statistically occupied b...
Resistance spot welding has recently been proposed for joining steel and aluminum alloys to reduce the weight increase strength of automobile bodies. However, Fe Al results in formation intermetallic compounds (IMCs) at interface. A thick IMC layer reduces joint strength, but it is difficult control thickness. Therefore, this study, a process that simultaneously achieves resistance heat generat...
Twenty-six metals and the oxidative status in 71 patients affected by Parkinson's disease and 44 healthy individuals were compared in order to identify potential biomarkers of the disease. In the patients, the following significant imbalances were found (p < or = 0.05): i) in serum, an increment of Ca, Mg, Ni, Si and V, and a decrement of Cd, Co, Fe, Li, Sn, Zn and Zr; ii) in blood, raised leve...
X-ray powder diffraction data for Mo2.85Al1.91Si4.81 are presented here. The new Mo2.85Al1.91Si4.81 compound was successfully prepared, using the self-propagating high-temperature synthesis (SHS) technique. The starting atomic mixture of reactant powders was Mo + 2(1 - x)Si + 2xAl with 0.2 ≤ x ≤ 0.5. The final powder compound obtained by the SHS technique was determined to be in x = 0.2; Mo(Si,...
In this study, the formation of the Al3Ti intermetallic compound at the junction interface of aluminum-titanium was investigated during deposition and annealing. The results illustrated that during the deposition process, one thin layer of Ti3Al2 intermetallic compound was created at the junction interface. During the annealing at 550 °C, this layer was transformed to the Al3Ti interm...
