A Schiff base surfactant 2-octanone ethylenediamine (OED) was in this study designed to improve the performance of alkaline zinc-nickel batteries that were synthesized and characterized by IR and XRD. Electrochemical experimental results showed that addition of OED surfactant in both zinc electrode and electrolyte effectively inhibited self-corrosion of zinc electrode and improved performance of zinc-nickel...
Deformation, stress and arch effect are problems of interest for high earth- rockfill dams. Deformations and stresses during construction, impoundment and operation stages of Lianghekou earth-rockfill dam were studied through numerical methods. The filling materials were modeled by using the Mohr- Coulomb and Burgers models. As a result, the maximum vertical displacement is located in the middle of...
