Magnesium-aryloxide and -amide compounds supported by amidinate ligands are accessible in two-steps from a suitable Grignard reagent. Both species are active for the dimerization of benzaldehyde. The slower initiation by the aryloxide was exploited in the isolation of a bis-mesitylaldehyde adduct.
In this study, microstructure and mechanical properties of diffusion joints between 5754, 6061 and 7039 aluminum alloys and AZ31 magnesium alloy were investigated. Diffusion joints were done between the alloys at 440 °C, for duration of 60minutes, at 29 MPa pressure and under 1×10-4 torr vacuum. The interface of joints was studied using optical (OM) and scanning electron microscopy (S...
UNLABELLED The glutamatergic mechanism of antidepressant treatments is now in the center of research to overcome the limitations of monoamine-based approaches. There are several unresolved issues. For the action of the model compound, ketamine, NMDA-receptor block, AMPA-receptor activation and BDNF release appear to be involved in a mechanism, which leads to synaptic sprouting and strengthened ...
Abstract Magnesium based niobium oxides (Mg–Nb–O) were prepared by solid-state reactions owing to understand the function of transition metal as promoters/catalysts for practical application. niobate (Mg 3 Nb 6 O 11 ) was synthesized first time in nearly pure form reported this context. MgNb 2 and Mg 4 9 oxidizing conditions; on contrary, preferred reducing environment. Stoichiometric mixtures ...
Due to sensitivity problems, (25)Mg remains a largely under-explored nucleus in solid state NMR spectroscopy. In this work at an ultrahigh magnetic field of 21.1 T, we have studied at natural abundance the (25)Mg solid state (SS) NMR spectra for a number of previously unreported magnesium compounds with known crystal structures. Some previously reported compounds have been revisited to clarify ...
With the growth of magnesium recycling market, risk fire and explosion has been raised over time. In particular, dross generated in process is not considered as a hazardous material even though it contains lot pure and/or compounds. There are few safety measures to prevent respond potential fires explosions protect employees. Therefore, this study aims identify appropriate reduce by looking at ...
Abstract Dissolved and particulate sodium, magnesium calcium are analyzed in ice cores to determine past changes sea extent, terrestrial dust variability atmospheric aerosol transport efficiency. They also used date if annual layers visible. Multiple methods have been developed analyze these important compounds cores. Continuous flow analysis (CFA) is implemented with instruments that sample th...
