It is shown that, when sputtered onto the surface of (111) Ir face in temperature range 1100-1250 K, beryllium atoms form a chemical compound stoichiometry 3 Be with concentration adsorbed N =5·10 14 cm -2 , after which newly deposited dissolve metal bulk. The itself destroyed due to dissolution 1250-1400 K an activation energy increasing from 3.2 eV 3.7 decreasing concentration. At T>14...

Treated sea water is the most significant source of water and surfactant floods. The various chemicals employed in treatment plants should be compatible with surfactant systems. Based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...
