The Effect of Transition Metals Incorporation on the Structural and Magnetic Properties of Magnesium Oxide Nanoparticles
Pure and doped magnesium oxide nanoparticles were successfully synthesized employing a sol-gel process. The synthesized nanoparticles were characterized by thermal differential analysis, X-ray powder diffraction, transmission electron microscopy, scanning electron microscope, energy-dispersive X-ray spectroscopy, and vibrating sample magnetometer. X-ray diffraction patterns confirmed the crysta...
متن کاملIsoxazole Functionalized Crosslinked Resin Complexes of Transition Metals as Polymeric Catalysts for Hydrogen Peroxide Decomposition
Crosslinked functionalized polymers are highly efficient in immobilizing transition metal ions. The activity of Fe(III), Co(II), Ni(II) and Cu(II) complexes of polystyrene bound Isoxazole resin have been tested towards the decomposition of hydrogen peroxide. The decomposition reaction followed a first order dependence on the concentration of both the substrates and the catalyst. The metal compl...
متن کاملKinetic Modification on Hydrogen Desorption of Lithium Hydride and Magnesium Amide System
Various synthesis and rehydrogenation processes of lithium hydride (LiH) and magnesium amide (Mg(NH₂)₂) system with 8:3 molar ratio are investigated to understand the kinetic factors and effectively utilize the essential hydrogen desorption properties. For the hydrogen desorption with a solid-solid reaction, it is expected that the kinetic properties become worse by the sintering and phase sepa...
متن کاملSurface Femtochemistry: Frustrated Desorption of Alkali Atoms from Noble Metals
The electronic excitation of chemisorbed Cs atoms through the coherent photoinduced charge transfer from the Cu(111) surface turns on repulsive forces that initiate the dissociative wave packet motion. Due to unusually slow electronic relaxation, with the interferometric time-resolved two-photon photoemission technique it is possible to follow the characteristic change in the surface electronic...
متن کاملHydrogen Desorption from Mg Hydride: An Ab Initio Study
Hydrogen desorption from hydride matrix is still an open field of research. By means of accurate first-principle molecular dynamics (MD) simulations an Mg–MgH2 interface is selected, studied and characterized. Electronic structure calculations are used to determine the equilibrium properties and the behavior of the surfaces in terms of structural deformations and total energy considerations. Fu...
