06 Aug 2003TL;DR: In this article, an improved wire bonding process for copper-metallized integrated circuits is provided by a nickel layer that acts as a barrier against up-diffusing copper, and the nickel bath is placed and remains in hydrogen saturation by providing a piece of metal that remains in the nickel plating tank before and during the plating process.
Abstract: An improved wire bonding process for copper-metallized integrated circuits is provided by a nickel layer that acts as a barrier against up-diffusing copper. In accordance with the present invention the nickel bath is placed and remains in hydrogen saturation by providing a piece of metal that remains in the nickel plating tank before and during the plating process.

TL;DR: In this article, an electrochemical quartz crystal microbalance (EQCM) was employed to monitor directly the growth of NiHCNFe films on gold substrates during electrodeposition as well as a result of sol-gel aggregation in colloidal nickel ferricyanide solutions used for modification.

TL;DR: In this article, a nickel-based catalyst with high activity at low temperature for partial oxidation of methane (POM) was synthesized by two-step preparation method, where Ni-nanoparticles supported on CeO2 nanoparticles were synthesized and a new procedure was developed where cetyltrimethylammonium bromide (CTAB) acted as morphology controlling agent and polyvinylpyrrolidone (PVP) as size controlling agent for nickel nanoparticles.
Abstract: The objective of the current study was to synthesize a nickel based catalyst with high activity at low temperature for partial oxidation of methane (POM). Ni-nanoparticles supported on CeO2 nanoparticles were synthesized by two step preparation method. First, 30–50 nm CeO2 was synthesized by solvo-thermal method and then Ni- nanoparticles were deposited over it following a newly developed procedure, where cetyltrimethylammonium bromide (CTAB) acted as morphology controlling agent and polyvinylpyrrolidone (PVP) as size controlling agent for nickel nanoparticles. The characterizations of synthesized catalysts were done by BET-Surface area, XRD, SEM, TEM, TPR, H2-chemisorpton, TGA and XPS analysis. The catalysts showed excellent coke resisting ability during POM and produces synthesis gas with H2/CO ratio almost 2. The catalyst activated methane at 400 °C with 10% methane conversion and converts methane almost completely at 800 °C. The catalyst showed above 98% methane conversion at 800 °C during 90 h of time on stream (TOS) reaction with H2/CO ratio 1.98. Average 5.5 nm Ni particles, use of CeO2 as a support played a very crucial role for methane activation at such lower temperature. The synergistic effect between small Ni-nanoparticles and CeO2 nanoparticles of Ni-CeO2 catalyst is the main reason for such activity. Detailed study of other reaction parameters like temperature, Ni loading, weight hourly space velocity (WHSV) was also carried out and reported.
