this paper focused on a novel method of electroless plating ruthenium (ru) on solid or porous substrates like porous stainless steel (pss) discs or ceramic tubes. a novel complexing plating bath of ru was developed. it is proven that ru can be deposited directly on these substrates by the bath at a temperature of 328 k and strong alkaline environment. tga, sem, edx and xrd confirmed the success...

This study investigated the hydrogen permeation property of cementite by fabricating bulk sample using process combining mechanical ball milling and subsequent pulse current sintering. The having a 96 vol% was successfully fabricated. prepared showed no signal during 3.5 day electrochemical test. morphology blister formed in indicated that diffusion coefficient is very small.

Elemental analysis was performed for the palladium foil through which the hydrogen gas penetrated. We analyzed sample surface by Time-of-Flight secondary ion mass spectroscopy and searched for newly produced elements during the gas permeation process. Significant increase of the counts for Cr, Fe, Cu and Ag were found after the permeation. These elements could have been produced by nuclear tran...

In previous chapters, the synthesis of a highly hydrogen selective membrane formed by the deposition of a silica layer on top of a Vycor glass substrate was discussed. In this chapter, the preparation of a composite membrane using a porous alumina support is described. This membrane showed a high hydrogen permeance of the order of 10 mol m s Pa at 873 K with selectivity of hydrogen over CH4, CO...
