nickelnickel oxidesoxidationThis paper describes the first stages of oxidation of nickel. Under suitable experimental conditions small isolated crystallites are formed prior to the occurrence of a continuous oxide film. The shape, size, and number of the crystallites depends on the crystallographic ...

It has become increasingly more clear that, for a number of reasons, the titanium aluminides will be the first “new” metallic materials introduced into commercial high temperature applications (probably aircraft gas turbines and automobiles engines) in many years. As a result a very ...
In the meantime, Y- implantation inhibited ion diffusion rate in the oxide scale and reduced the size and number of interfacial defects, hence remarkably enhanced the adhesion of protective NiO oxide scale formed on nickel substrate. Keywords: oxidation, ion-implantation, acoustic emission, ...
This type of antibiotic holds the promise of self-destruction over a number of hours of exposure to light, so that it would not allow selection of resistance in the environment. (4) (5) The synthesis and inhibitory activity toward human leukocyte elastase of new 7α-methoxy and 7α-chloro...
number of corresponding M metals (Supplementary Table2). Figure2dplots the density of accumulatedMOOH(++)species, measured as a function of applied potential for all three samples under conditions of electrocatalytic water oxidation. It is apparent that the Ni(Fe)OOH and FeOOHNiOOH ...
In step V, the front subcell with a structure of NiO/SAM/WBG perovskite/C60/ALD-SnO2was deposited, in which NiO is nickel oxide and SAM is a self-assembled molecule. Solvent penetration and thermal damages are two major issues while building front subcells on the back cells. As shown in...
Operating fuel cells in alkaline environments permits the use of platinum-group-metal-free (PGM-free) catalysts and inexpensive bipolar plates, leading to significant cost reduction. Of the PGM-free catalysts explored, however, only a few nickel-based ma
Preparation of 0.7Ni/S-1 0.7Ni/S-1 was also prepared by the above impregnation procedure with Ni(NO3)2·6H2O. Synthesis of 2.3Ni/HY-IE and 3Ni/HY-IE The 2.3Ni/HY-IE and 3Ni/HY-IE samples were synthesized by nickel exchange of the HY support using a template ion-exchange procedure...
