FINALLY YOU HAVE A POSSIBILITY OF PRECIPITATING AN ELECTROLYTIC PROTECTIVE COAT FROM AN ELECTROLYTIC DISSOLUTION IN THE FORM OF BASIC COPPER CARBONATES.TRIQUET, CHRISTIAN DIPL.-ING.PRIGGEMEYER, STEFAN DR.PRIGGEMEYER, SONJA DR.BARTKE, FRANZ-JOSEF...
Corrosion of iron, which is known as rusting, is a serious problem as enormous amount of money is spent every year to replace damaged iron. Similarly, copper reacts with moisture and. CO2 in air to form a green coloured coating of basic copper carbonate on its surface. Silver acquires a ...
benzoic acid, salicylic acid and basic copper carbonate in the solid state have been recorded. The measurements have been made at various temperatures for fixed sizes of the particles at constant compression. The products are characterised by infrared and reflectance spectra. The reactions are ...
Genetic models for iron oxide–apatite deposits are controversial and span a spectrum from orthomagmatic to hydrothermal endmembers. This lack of consensus is rooted in uncertainties as to the nature and origin of ore-forming fluids in these systems. Her

Here, we have developed a palladium- catalysed general coupling for the efficient connection of two tertiary carbon atoms: Speci- fically, propargylic carbonate has been treated with a fully loaded soft functionalized nucleophile to connect such two fully loaded carbon atoms with a simple palladium ...

(near-)realistic conditions. Over time, hybrid interfaces tend to degrade when exposed to environmental conditions. The culprits are predominantly water, oxygen, and ion diffusion resulting in bond breakage due to changing acid–base properties or leading to the onset of corrosive de-adhesion ...
The Neoproterozoic Schisto-Calcaire Group (630 to ca. 580 Ma) was deposited on an extensive carbonate shelf in the margin of the Congo Craton in the Niari-Nyanga and Comba subbasins (Gabon and Republic of the Congo). It consists of three carbonate-dominated subgroups (SCI to SCIII, up ...
