This contribution firstly presents particularities of mineral chemistry of platinum-group elements (PGE) mineralization from placer deposits linked to the Bor-Uryakh massif of the Maimecha-Kotui Province, northern part of the Siberian Craton. The chemical composition of PGE mineralization has been ...
In this paper, the chemical composition, pharmacological effects, clinical applications, and adverse reactions of cinobufacini are summarized. However, the extraction of monomer components of cinobufacini, the relationship between different mechanisms, and the causes of adverse reactions need to be ...
The particle cores tested in these studies include black carbon, silver, gold, and platinum nanoparticles. These results demonstrate that SP vaporization is capable of providing enhanced organic chemical composition information for a wide range of organic coating materials and IR absorbing particle cores...
ESI-MS experiments confirmed the expected composition of [Cd30L12] (Fig. 3c), exhibiting a series of signals derived from the 14+ to 25+ ions, which correspond to {[Cd30L12]—nPF6}n+ (where n = 14~25). Although the isotope pattern of each charge state was unclear in the mas...

Copper—zinc alloys Nitric acid (1.40) 80 ml 5 s 40 Use periods of 5 s immersion followed immediately by washing in a rapid stream of water. Slight variations in composition are needed for α—β and β—γ brasses to prevent differential attack. With β—γ alloys, a dull film forms ...
In the past, palladium as a member of the platinum group metals was mainly known as an expensive noble metal. Probably, only fast hydrogen absorption into bulk palladium reminded of its unique catalytic activity. At the beginning of the twenty-first century, detailed studies of the electron stru...
