Nickel substrate

The other type of nickel electrode involves constmctions in which the active material is deposited in situ. This includes the sintered-type electrode in which nickel hydroxide is chemically or electrochemically deposited in the pores of a 80—90% porous sintered nickel substrate that may also contain a reinforcing grid. 

When PMMA was adsorbed onto an iron substrate, four components were not sufficient to explain the C(ls) spectrum (see Fig. 21b) and a fifth component had to be added at 288.1 eV as shown in Fig. 21c. This component was attributed to carboxyl groups, indicating that the ester groups were partially hydrolyzed. Similarly, Leadley and Watts found that there were five components in the C(ls) spectrum of PMMA spin-coated onto aluminum, copper, and nickel substrates 124].

The white bar shows the scale in micrometres (p.m) (thousandths of a millimetre), (a) The initial stages of diamond growth on a nickel substrate, showing individual diamond crystallites nucleating in scratches and crevices created on the surface by mechanical abrasion, (b) a randomly oriented him,...

The resistance between the semiconductor deposit and the nickel substrate was less than 2 ohm, indicating a good contact between deposit and substrate. 

The influence of benzylidene acetone on the electrodeposition mechanism of Zn-Co alloy was investigated [436]. A relationship between corrosion resistance, microstructure, and cobalt content in Zn-Co alloys was investigated [437] using X-ray photoelectron spectroscopy (XPS) and Auger spectroscopy [438]. The role of vitreous carbon, copper, and nickel substrates in Zn-Co deposition from chloride bath was analyzed [439]. 

Epoxies are commonly used to bond nickel substrates. However, the nickel alloys often find applications at temperatures higher than most organic adhesives are capable of resisting.

Moreover p(2x2) surface reconstructions were observed for NiO(lll) thin films grown on gold and nickel substrates [95, 96]. Early experiments on NiO(lll) also showed complex reconstructions attributed to Si segregation [97]. 

The sulfur adsorbate-nickel substrate system has also given rise to considerable interest ) and the structure of the vaiious faces have been the subject of theoretical and experimental studies in which the Auger-LEED data, have been complemented by ion-neutralisation spectrometric (INS) ) and UPS ) determinations. It has been shown that different coverages of adatoms lead to different forms of adatom bonding and modification of the whole electronic structure of the surface ). 

The CO disproportionation reaction (37) has been used as the carbon deposition pathway in the majority of studies 48, 54, 56, 58-60). Carbon has also been deposited via hydrocarbon hydrogenolysis 54, 61-63) and, notably, via the FT synthesis reactions 35-37, 45). Particularly the initial studies involved nickel substrates ruthenium, cobalt, and iron were also studied. 

Bei Verhaltnissen von Raney-Nickel Substrat 1 10 bis 1 2 werden in der Regel keine Hydrogenolysen beobachtet (vgl. Tab. 58, S. 228).
