“…Furthermore, at the beginning of returning, the fresh body of O. violaceus decays fast, as it contains a large amount of labile organic matter that can provide carbon resources and nutrients for microorganisms; with the extension of ipping time, the easily decomposable organic matter in the GM residues gradually decreases, while the proportion of recalcitrant crude bers, lignin, etc., increases, thus resulting in a relatively slower mineralization rate at our sampling. This was con rmed by the C/N ratio of O. violaceus increasing from the initial 9.7 to 15.3 after 126 days' of decomposition (Liu et al 2013). In this case, our results represented only a single time point and variations in phenological differences cannot be considered, which is the drawback of this study.…”

Using green manure (GM) in rotations is a sustainable approach to cleaner production and soil CO2 emissions mitigation, yet the microbial mechanism governing soil organic carbon (SOC) mineralization from legume fields remains to be elucidated. To determine whether the GM-based rotation was superior to the conventional continuous peanut monoculture, a seven-year field experiment including two cropping regimes, peanut continuous monoculture (P) and peanut-Orychophragmus violaceus rotation (PO), was performed. Microbial properties and C-degradation enzyme activities in the rhizosphere and bulk soil of peanut fields were explored, with SOC mineralization (Kc) and its temperature sensitivity (Q10) determined in the laboratory. O. violaceus incorporation as a GM enhanced soil moisture, pH and mineral nitrogen contents, which increased the bulk soil bacterial alpha diversity and reduced rhizosphere fungal richness. GM incorporation promoted saprotrophs (Agaricales), enriched beneficial microbes (Bacillus) and inhibited pathogenic fungi (Fusarium), thus alleviating continuous monoculture obstacles and increasing yields. The bacterial interaction complexity was increased, but the fungal interaction complexity was reduced. Moreover, GM not only decreased the rhizosphere Q10 (by 14.9%) due to decreased rhizosphere SOC but also reduced the bulk soil Kc (by 23.9%) due to the intensified C limitation, indicating that the C loss of bulk soil is currently low and that of the rhizosphere will be limited under future warming. This study provides new insight into soil C mineralization in legumes at the microenvironmental scale, and improves our projections of legume soil C loss under future climate change scenarios.

“…In the third stage, as shown in Figure 8c,d, the TiCu 2 phase, which is spread in an island-like pattern on the front side of the reaction layer, is formed via the reaction of Ti + 2Cu → TiCu 2 in the middle of the joint, and the addition of LAS promotes the transformation of Ti-Cu compounds into TiCu 2 due to Ti being consumed by LAS [34]. As the holding time increases, the thickness of the reaction layer increases, and the formation of a continuous reaction layer inhibits the further diffusion of Si and C into the brazing material at the interface.…”

In this work, SiC ceramics were successfully brazed at 900 °C using a composite brazing filler, and the effects of holding time and LiAlSiO4 addition on the interfacial microstructure and mechanical properties of the joints were systematically investigated. The results showed that the brazed joints were devoid of obvious defects, and the joint structure was mainly composed of SiC/Ti5Si3/TiC + TiCu2 + TiO2 + LAS + LiAlSi2O6 + Cu (s, s) + Ag (s, s)/Ti5Si3/TiC/SiC. When the brazing temperature was 900 °C for 10 min and the LiAlSiO4 addition was 1 wt%, the SiC brazed joints reached a maximum shear strength of 106.47 MPa, which was 4.7 times higher than that of the joints without LiAlSiO4 addition under the same conditions. According to theoretical calculations, the addition of LAS can successfully reduce residual stresses in SiC brazed joints and enhance the joint strength.
