electron shell
3.Together with luminescence spectra, X-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonant (EPR), core-shell structure of nanocrystalline ZnO was put forward.
5.The surface of nano-AgCl modified by polyacryamide with microemulsion template has been performed. Transmission electron microscopy (TEM) analysis demonstrates that the composite is a core-shell structure of AgCl/poly acryamide ( PAM) composite nanoparticle.
6.X ray diffraction(XRD), transmission electron microscopy(TEM), UV Vis spectroscopy and photoluminescence spectroscopy were employed to characterize the obtained core shell structures. The thickness of the amorphous SiO2 shell ranges from 10 to 30 nm, and increases with the concentration of the TEOS used.
7.Interferograms were acquired at different time during pinch process. The radial distributions of local electron density were calculated. The maximum local electron density above the anode end was measured about 1.2×10~(19) cm~(-3) and that of the outer plasma shell 2×10~(18) cm~(-3) when plasma began pinching.
9.distorted wave Born approximation (DWBA) and so oa On the other hand, cross sections for the removal of atomic inner-shell by electron impact are needed in fields of application including materials analysis by electron-probe microanalysis (EPMA), surface analysis by Auger-electron spectroscopy (AES), and thin film analysis by electron energy-loss spectroscopy (EELS).
10.A functional-link net(FLN) was employed to correlate a set of atomic structural descriptors, such as electric charges ( Z), ionic radii ( r), electron numbers in the valence layer (f, d, s) , principal quantum numbers in the outer-shell ( n ) , electronegativity (xp ) , and the factor of adaptive valence orbit number(w) of the metal ions with known stable constants (logK) of ethylenediamine tetraacetic acia complexes of 60 metal ions.
