A catalyst having a mixture of Ru and RuOx, wherein x is greater than 0 and equal to or less than 2, supported by a suitable metal oxide support material is suitable for the heterogeneous catalytic gas phase direct methane production from hydrogen and carb ...
Motor parts produced by casting are subjected to particularly high local stresses and must be reinforced by high-strength inserts. The insertion is normally made mechanically after casting, but, if good adhesion could be obtained, it would be preferable to ...
We present experimental evidence of a previously unknown aluminum oxidation state due to chemisorbed atomic oxygen. This new oxidation state has been detected at room temperature on the chemically shifted Al 2p core level by photoemission spectroscopy. The ...
Preforms of nickel powder or nickel/alumina powder blends were infiltrated with molten aluminum to produce nickel aluminides. Application of a pressure of 3.6 and 6.9 MPa on the melt allowed infiltration of preforms with nickel powder particles between 5 a ...
In the search for a DSA-type electrode for oxygen evolution in acidic solns., nine binary coatings with IrO2, RuO2, Pt as conducting component, and TiO2, ZrO2, Ta2O5 as inert oxides, were deposited on titanium, examd. for their microstructural properties a ...
Various catalysts were used in a systematical study of selective catechol methylation to 3-methylcatechol (I) in a fixed-bed reactor of 35-mm diam. and 16-cm length. Reaction products were analyzed by gas chromatog. with mass spectrometric detection. Alumi ...
The local deposition of metal structures by thermal dissociation of trimethylaluminium, dimethylzinc and dimethylcadmium on GaAs surfaces heated by a CW krypton laser has been investigated. Piles of amorphous aluminium and zinc and crystalline structures o ...
The type of reactor dets. the kinetics of the dehydration of EtOH to Et2O on g-Al oxide, as demonstrated by continuous and discontinuous reactions. [on SciFinder (R)] ...
