New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

A fundamental study of scale formation of calcium carbonate (CaCO3) for producing oil wells has been carried out. This article presents the study of the prediction of salt deposition in two different synthetic formation waters and investigates the effects of temperature and pressure on calcium carbonate precipitation. The dependence of the induction period of the precipitation of calcium carbon...

In this paper, a numerical solution procedure is presented for the free and forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of Timoshenko beam theory. The influences of surface piezoelectricity, surface elasticity and residual surface stress are taken into consideration. Using Hamilton’s principle, t...

As a common geological material, soil is key aspect of construction engineering. Soil has typical multi-scale characteristics, but current methods analyze these characteristics only in regard to geometric space. More exploration the coupling influence mechanism basic properties particles on microstructure and macroscopic needed. This study analyzed scale mineral composition surface energy at mi...
