Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components
Journal of Raman Spectroscopy, EarlyView.Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.

Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion
Materials and Corrosion, EarlyView.Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

Hot Corrosion Type X: Behavior of Mo‐Si‐B at Different Temperatures
Materials and Corrosion, EarlyView.The temperature‐dependent mechanism for Mo‐Si‐B is investigated by studying the hot corrosion resistance of Mo‐Si‐B at 500°C–900°C. Post‐testing analysis via XRD, SEM, Raman and EPMA is used to reveal the degradation mechanisms. Na2MoO4, which forms under Na2SO4 deposits, is responsible for dissolving the surrounding material due to its lower melting ...
