Some observations indicated that the high Ca 2+ sensitive phenotype of PMR1 defective yeast strains may be the most relevant in this respect. Here we show that the total cellular calcium response of a pmr1 S. cerevisiae upon extracellular Ca 2+ challenge is decreased compared to the wild ...
Also, the proposed reaction is expected to generate a gradient in the activity of water across the "hydrated" MgO layer, in accordance with reports in the literature35. Because the process depends on hydroxyla- tion of the MgO GBs it is expected to depend on the activity of water in...
In addition, visual observations of the slag accumulating on the walls of boiler steam tubes showed a surprisingly different and improved character, texture and volume when compared to visual observations of boiler steam tubes with slag from fuel combusted in the absence of the present mixed metal...
Here, the passive film was completely destroyed, while deep black voluminous reaction products formed. The latter were easy to rinse off after the experiment, leaving a shallow depression on the sample exposure area. The observations described can be explained by the increased roughness leading to ...
Regarding CO-PrOx performance, the following observations were made: (i) the conversion of CO, O2 and H2 increased with an increase in reaction temperature, where the Co-based oxide catalysts exhibited higher conversions than the Fe-based oxide catalysts within the temperature window studied (i.e...
