In this method, the surface of the metal to be coated is modified by diffusing into it at a high temperature into a metal or an element, which would provide the required resistance when combined with the parent metal. Such coatings are called 'diffusion coatings' Diffusion coatings can be ap...
Phase-field method (PFM) has become a mainstream computational method for predicting the evolution of nano and mesoscopic microstructures and properties during materials processes. The paper briefly reviews latest progresses in applying PFM to understand
We found that the metallic ground states appeared in the films grown at low temperatures. The electronic ground states were further investigated by the electronic-structure calculations. Results suggest that the electrical properties of Ti2O3 films were governed by the c/a ratio of the crystal ...
We believe that cellulose acts as a buffer alleviating the mechanical stress to which the element is subject during the lithium insertion/de-insertion process. In fact, an electrode made from nanometric Sb prepared in the absence of cellulose was found to perform poorly; thus the capacity ...
In-situ produced Ag nanoparticles... S Guo,S Dong,E Wang - 《Chemistry》 被引量: 0发表: 2008年 Finite Element Analysis of Epoxy (Ly-556) Glass Fiber Filled Aluminium Circular Section Hollow Column Composite materials are materials made from two or more constituent materials. It consists of ...
The metallic structures in this study are Ru x /Co x , Ru x /Pt x , and Ru x /Al x , each individual layer having a thickness of x = 10 nm. For comparability, each one of the four constituent metals was also produced as single-element sample with 10 nm layer thickness. ...
Patent Literature 1 proposes a high-strength porous metallic body that is obtained by applying a coating material containing strength-enhancing fine particles formed of an oxide, a carbide, a nitride, or the like of an element in group II to VI in the periodic table to the surface of the ...
Lithiated metallic molybdenum disulfide nanosheets for high-performance lithium–sulfur batteries Introduction Element sulfur in nature is an insulating solid consisting of rings of S atoms.1However, at high pressures (e.g., exceeding 90 GPa), it transforms from an insulator to a metallic phase ...
Its modular structure allows solving of different field equations in a fully coupled way with a staggered approach, using Fast Fourier Transform (FFT) and Finite Element (FE) based solvers provided by the PETSc numerical library21,118,171. The pre- and post-processing of DAMASK facilitates ...
The present invention provides a separator for a fuel cell that comprises a metal substrate that contains at least one metal element M and a surface layer formed on a surface of the metal substrate and that contains at least one conductive oxide represented by LaMxO3 (wherein x=0 to 1)....
