Elemental, Morphological, and Corrosion Characterization of Different Surface States of Co-Cr Alloy for Prosthodontic Applications

International Journal of Electrochemical Science, 2016
In this study, four different groups were prepared in a cast model of an arch that received four implants made with a Co-Cr dental alloy. The surface of each group was prepared by four different surface treatments, including sandblasting with Al2O3 ...

Finite Element Analysis of Bearing Capacity on the Composite Foundation of Group Pile

IOP Conference Series: Earth and Environmental Science, 2019
Abstract In order to study the bearing characteristics on the composite foundation of group pile, the influences of variation of pile length, elastic modulus, spacing and cushion thickness on the bearing capacity for the composite foundation of group pile were investigated by finite element method.

Structural and electrical properties of Li4Ti5O12 anode material for lithium-ion batteries

Results in Physics, 2018
In this work we investigate Li4Ti5O12 (LTO) anode material synthesized by conventional solid state reaction method calcined at 850 °C for 16 h. Thermal analysis reveals the temperature dependence of the material properties.
