60) to be used for fabricating jewellery, so alloying additions are made to increase the hardness. Platinum jewellery alloys usually have platinum contents of 90 wt.% and higher. The most common alloys are hallmarked as 950 platinum (95 wt.%). Unlike carat gold (Au) jewellery alloys, where relatively large additions can be made (to alter the properties of the alloy such as its hardness or colou...
Microscopy and diffraction measurements are presented of ultrathin binary alloy films ruthenium molybdenum that obtained by standard sputter deposition . For compositions close to Ru 50 Mo , we find the be amorphous. The amorphicity is accompanied a significant reduction roughness with respect equally thick either or molybdenum. We ascribe this absence grain structure characteristic polycrystal...
Sluggish kinetics of anodic hydrogen oxidation reaction (HOR) in alkaline media, which arises from the two orders magnitude lower HOR activity alkali than that acid media for platinum group metals, hinders commercial implementation anion exchange membrane fuel cells (AEMFCs). Consequently, development platinum-based catalysts combined with high efficiency and durability is urgently required. He...
Two-dimensional boron-carbon-nitride materials exhibit a spectrum of electronic properties ranging from insulating to semimetallic, depending on their composition and geometry. Detailed experimental insights into the phase separation and ordering in such alloy are currently lacking. Here we report the mixing and demixing of boron-nitrogen and carbon phases on ruthenium (0001) and found that ene...
A trace level concentration of osmium(VIII) has been quantitatively extracted from 1.0 M hydrochloric acid with 0.087 M N-n-octylaniline as a stationery phase on silica gel. Osmium(VIII) has been eluted with 5.5 M, 25 mL hydrochloric acid and determined by spectrophotometric method. Various parameters influencing the extraction, such as acid concentration, reagent concentration and flow rate ha...
Abstract We report the hydrogenation catalytic activity application of molybdenum–ruthenium (MoRu) solid‐solution alloy nanoparticles (NPs) as catalysts for 1‐octene and 1‐octyne. The structure MoRu NPs was confirmed through scanning transmission electron microscopy (STEM) coupled with energy‐dispersive X‐ray spectroscopy (EDX), powder diffraction (PXRD) measurement. these toward 1‐octyne in te...
Neutral or cationic arene ruthenium complexes providing both hydrophilic as well as hydrophobic properties due to the robustness of the ruthenium-arene unit hold a high potential for the development of metal-based anticancer drugs. Mononuclear arene ruthenium complexes containing P- or N-donor ligands or N,N-, N,O- or O,O-chelating ligands, dinuclear arene ruthenium systems with adjustable orga...
