The rate coefficient for radiative and dielectronic recombination of berylliumlike magnesium ions was measured with high resolution at the Heidelberg heavy-ion storage ring TSR. In the electron-ion collision energy range 0–207 eV resonances due to 2s → 2p (∆N = 0) and 2s → 3l (∆N = 1) core excitations were detected. At low energies below 0.15 eV the recombination rate coefficient is dominated b...

in the present study we focused on the electronic and structural properties of na and mg adsorption on the surface of the (6, 6) armchair sicnts. the adsorption energy (eads), band gap energy (eg), partial density of state (pdos), chemical potential (μ), global hardness (η), electrophilicity index (ω), global softness (s), work function values (φ) and work function change (δφ) are calculated by...

magnesium hydroxide mg(oh)2 nanorods with diameters of 90±10nm and lengths of more than 2μms were prepared by a simple route at ~75oc in ambient air. the approach is based on reaction of magnesium powder and de-ionized water without the use of any harmful, toxic or corrosive reagents. characterization using x-ray diffraction (xrd) shows single crystalline structure of mg(oh)2 (brucite) whereas ...

Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...
