This study describes an original method developed for the shaping of composite solid oxide fuel cell (SOFC) anodes including either nickel or copper as metal.

We use two different ab initio quantum mechanics methods, complete active space self-consistent field theory applied to electrostatically embedded clusters and periodic many-body G0W0 calculations, to reanalyze the states formed in nickel(II) oxide upon electron addition and ionization. In agreement with interpretations of earlier measurements, we find that the valence and conduction band edges...

Abstract Functional thin films with a compositional gradient were deposited by sputtering method mixed powder targets. The composition ratio of nickel (Ni) and stainless steel (SUS304) was varied over the film thickness using several types oxide Our results indicate that nickel-doped stainless-steel successfully prepared on both Si substrates mixing controlled powder.

Aluminium oxide (Al2O3), commonly known as alumina, is a widespread naturally occurring compound that has a broad range of industrial applications. Besides its use as a pigment or abrasive, alumina also plays a vital role as catalyst support for desulfurization or hydrogenation reactions. In the latter case, the active phase on the catalyst often consists of nickel metal nanoparticles. The inte...

The electronic modification of TiO(2) with highly dispersed NiO particles smaller than ca. 2 nm by the chemisorption-calcination-cycle technique has given rise to a high level of visible-light-activity exceeding that of iron oxide-surface modified TiO(2) simultaneously with the UV-light-activity being significantly increased.

Reduction of an oxide in hydrogen is a method frequently employed in the preparation of active catalysts and electronic devices. Synchrotron-based time-resolved X-ray diffraction (XRD), X-ray absorption fine structure (NEXAFS/EXAFS), photoemission, and first-principles density-functional (DF) slab calculations were used to study the reaction of H(2) with nickel oxide. In experiments with a NiO(...

Nickel oxide (NiO) thin films were prepared by nebulized spray pyrolysis (NSP) technique. The films are having more uniform thickness and there is no pinhole. Nickel oxide thin films have been deposited using 0.3M aqueous solution of nickel chloride NiCl2.6H2O onto microscopic glass substrates, which were chemically and ultrasonically cleaned before coating. The film depositions are carried out...

We have developed a multilayer, multichannel microfabricated reactor that uses elemental fluorine as a reagent and generates hydrogen fluoride as a byproduct. Nested potassium hydroxide etching (using silicon nitride and silicon oxide as masking materials) was developed to create a large number of channels (60 reaction channels connected to individual gas and liquid distributors) of significant...
