TL;DR: In this article, three diffusion coatings (Cr, Ni + Cr, Ni-P + Cr) on a ferritic-martensitic X20CrMoV12-1 steel were investigated in a biomass-co-firing atmosphere in comparison to uncoated austenitic DMV 310 N.

TL;DR: The P-LinK method not only minimizes experimental effort and significantly reduces time demands but also requires only a single cloning and transformation step in order to generate multiple linker variants (1 to 16 amino acids long), making the approach technically simple and robust.
Abstract: Fusion protein construction is a widely employed biochemical technique, especially when it comes to multi-component enzymes such as cytochrome P450s. Here we describe a novel method for generating ...

TL;DR: In this article, the behavior of scales on 12Cr-1Mo steel was investigated under isothermal conditions at 650°C and under thermal cycling conditions between 650 and 300°C (200°C).
Abstract: Soot-blower operation leads to thermal-cyclic-oxidation conditions of heat-resistant steels in conventional power stations. The consequence may be failure of the protective oxide scales and increased corrosive attack. The behavior of protective oxide scales on 12Cr-1Mo steel was investigated under isothermal conditions at 650°C and under thermal cycling conditions between 650 and 300°C (200°C). The tests were performed in air, air + 0.5%SO2, simulating the fire side, and Ar-5% H2-50% H2O, simulating the steam side. Complete heat-exchanger tubes were used as specimens. The main instrument for the detection of scale failure was acoustic-emission analysis. In air and air + 0.5% SO2 the M2O3 scales with M = Fe, Cr were very thin and did not show significant failure either during isothermal or during cyclic oxidation. The thicker scales formed in Ar-5% H2-50% H2O, consisting of several partial layers, failed even during isothermal oxidation due to geometrically-induced growth stresses in the scale. Thus, in the thermal-cycling cooling periods there was only very little additional scale cracking. The scale behavior can be explained consistently by applying the existing quantitative models.

TL;DR: This work identified the kanamycin resistance gene and the transcription factor encoding rhaR gene to be causal for the growth defect in P. putida and introduced a mutation in the plasmid-encoded rep gene, thus enabling construction of the non-toxic variant pMiS4.
