TL;DR: Using the Pt-(O2) electrode as an indicator electrode for the O2− concentration of a sulphate melt, potentiometric acid-base titrations have been carried out at 625°C in the eutectic Li2SO4-K2SO 4-Na2O4 melt as discussed by the authors.

TL;DR: In this paper, the corrosion behavior of an electroless Ni-P coating on low-Cr X20CrMoV12-1 steel as a cost-efficient substrate-coating combination is investigated in molten NaNO3-KNO3 nitrates at 600°C.

TL;DR: In this paper, the parameters of erosion corrosion in particle containing liquids are investigated. Butteau et al. demonstrate in which way the erosion corrosion are acting, using a flue gas desulphurization plant.
Abstract: Stromende, partikelhaltige Flussigkeiten wirken je nach ihrer Korrosivitat in unterschiedlicher Weise auf Metalloberflachen ein. Mit Hilfe elektrochemischer Messungen wird gezeigt, wie sich die Parameter der Erosionskorrosion auswirken. Als Korrosionssystseme dienen acht Eisenwerkstoffe, die in einer feststoffhaltigen Quencher-Losung einer Rauchgasentschwefelungsanlage exponiert werden.
Electrochemical aspects of erosion corrosion in particle containing liquids
Flowing, particle containing liquids induce various effects on metal surfaces according to their corrosivity. Electrochemical measurements demonstrate in which way the parameters of erosion corrosion are acting. As corrosion systems eight ferrous materials are chosen which are exposed to a solid containing quencher liquid of a flue gas desulphurization plant.

TL;DR: The demonstration of a CPO isogene which is expressed as a secreted and active CPO clarifies the nature of this isoenzyme already identified in earlier reports.
Abstract: Inspection of transcriptome data from the chloroperoxidase (CPO)-producing fungus Caldariomyces fumago DSM1256 led to the discovery of two distinct CPO mRNA sequences. This strain could be shown to contain the newly identified isogene as well as produce and secrete both isoenzymes. The CPO2 enzyme bears high sequence similarity to the well-characterized CPO (87% identity for the mature proteins). It shows two insertions in the signal peptide and in the C-terminal propeptide, and one deletion in the mature polypeptide close to the C-terminus. Furthermore, it lacks one of the serine residues known to be O-glycosylated in the CPO sequence. The demonstration of a CPO isogene which is expressed as a secreted and active CPO clarifies the nature of this isoenzyme already identified in earlier reports. A structure model comparison shows a high conservation of the active site and the substrate channel, suggesting very similar catalytic properties.

TL;DR: In this paper, a literature survey had been performed leading to the conclusion that either particle or fiber reinforced MoSi 2-based materials or RSiC coated with a MoSi2-based layer are suitable for applications at such high temperatures.
Abstract: The topic Materials for temperatures above 1500 °C in oxidizing atmospheres is discussed in a 3 part publication. In the first part a literature survey had been performed leading to the conclusion that either particle or fiber reinforced MoSi 2 -based materials or RSiC coated with a MoSi 2 -based layer are suitable for applications at such high temperatures. In the present part such material systems are investigated experimentally at 1500 and 1600 °C with respect to their oxidation resistance in air. Particular interest was given to the influence of the Mo 5 Si 3 content in MoSi 2 and the influence of second phase particles in MoSi 2 consisting of ZrB 2 and SiC. Furthermore, the oxidation resistance of several dip-coatings on RSiC which were manufactured from a polysiloxane precursor by subsequent pyrolysis were also investigated. Part III which reports about contact corrosion between different materials at these temperatures will follow in the next issue.
