Summary: The study found that as the temperature increases, the spacing of dislocation networks in the gamma/gamma' interface decreases, while the minimum creep rate increases non-linearly. This is due to the enhanced dislocation-climb in the interface and gamma'-cutting by a <010> superdislocations.

Summary: The nutritional condition of seed mussels used in New Zealand's Greenshell mussel aquaculture industry shows high variability, which may contribute to the marked variation observed in spat performance. Environmental factors that limit feeding during harvest and transport of spat are likely influencing the quality of spat used by the industry. Measures to improve the quality of wild spat supply, such as testing nutritional condition and developing nursery culture methods and artificial spat feeds, are needed.

Summary: The structural modulations in multiferroic Bi4.2K0.8Fe2O9+delta (BKFO) nanobelts have been uncovered by scanning transmission electron microscopy (STEM). The displacive modulations can be decomposed into a transverse wave and a longitudinal wave, whose amplitudes and phases are layer-dependent. This study may help to understand and optimize the magnetoelectric coupling effect in BKFO.

Summary: This study investigates the formation of boron carbide superhard particles through a liquid-phase reaction at high pressure and high temperature. The synthesized particles exhibit a rhombic hexecontahedron morphology with twelve five-vertex stars. Electron microscopy and X-ray diffraction were used to analyze the crystal structure of these particles, revealing multiple cycling twinning rather than quasi-crystalline symptoms. The specific shape of the particles is explained by the decrease of surface energy during formation at high pressure and high temperature.

Summary: Gold ore from the Krumovgrad mine in Bulgaria is processed by flotation after grinding and regrinding stages to achieve the desired liberation size of the electrum. A study using SEM-based automated mineralogy analyzes the occurrence of electrum in the processing scheme and discusses its impact on precious metals recovery. The study finds that the Au/Ag grade ratios of electrum increase in the concentrate streams and decrease in the tailings. Furthermore, particles with zones highly enriched in gold are more frequently observed in the cleaner concentrate, suggesting the effectiveness of staged flotation reactors for recovering ultrafine gold.

Summary: In this study, tussock wetlands dominated by Carex appendiculata were selected, and the plant diversity and soil bacterial community were analyzed. The results showed significant differences in bacterial community composition, diversity, and functions under different levels of plant diversity. Therefore, the methods used for establishing artificially restored wetlands are recommended for Carex tussock wetland restoration.

Summary: This study aimed to explore the effects of three different cropping patterns on the abundance of nitrogen-cycling genes in saline-alkali soils. The results showed that rotation and mixture promoted soil nutrients and significantly influenced N-cycling functional genes. Rotation reduced the abundance of nifH, AOA, narG, and nosZ, while increasing the abundance of AOB. Mixture decreased the abundance of AOA, narG, and nosZ, while increasing the abundance of AOB and nxrB. Rotation and mixture not only reduced soil salinity but also improved soil fertility and nitrogen cycling.

Summary: This study investigates the effects of elevated CO2 concentration and temperature on the photosynthetic characteristics of Populus simonii x P. nigra '1307' leaves. The results show that elevated temperature increases chlorophyll concentration, while elevated CO2 concentration enhances electron transfer capacity. The superimposed effect of the two factors alleviates the photosynthetic inhibition caused by elevated temperature.

Summary: The study examined the impact of soil cultivation and natural restoration on bacterial microbial communities and functions in cold-region wetlands using 16SrRNA gene fragments and high-throughput sequencing. The dominant bacteria in the tested soil samples were Actinobacteriota, Acidobacteriota, Proteobacteria, Chloroflexi, and Firmicutes. Analysis revealed significant differences in bacterial communities between natural restoration and cultivation farmland. Functional analysis showed that soil cultivation and natural restoration patterns can alter the abundance of soil functional microorganisms, particularly chemoheterotrophy and aerobic chemoheterotrophy bacteria. These patterns also resulted in significant differences in the abundance of aerobic, facultatively anaerobic, and stress tolerant bacteria in wetland.

Summary: In this experiment, the impact of reclamation and restoration on soil microbes and biogeochemical processes in cold region wetlands was investigated. Different treatments, including cultivated and restored wetlands, were analyzed for changes in soil properties and microbial communities. The results showed higher contents of SOC, TN, and TP, as well as higher diversity indices, in the wetland nature reserve compared to upland and paddy fields. The dominant bacterial phyla in the reclaimed and restored soils were Actinobacteria, Acidobacteria, Proteobacteria, Chloroflexi, and Firmicutes. The structure of microbial communities was influenced by environmental factors driven by reclamation and restoration modes, such as AP, TP, AK, TK, TN, and SOC.

Summary: This study investigated the changes in soil bacterial microbial communities and functions driven by land-use patterns in the Hongxing National Nature Reserve of Heilongjiang Province using 16SrRNA gene fragments and high-throughput sequencing. The results showed significant differences in soil properties between wetland, farmland, and forestland soils. Wetland soil had higher water content, soil organic carbon content, and total nitrogen and phosphorus contents compared to farmland and forestland. The dominant bacteria in the tested soil samples were Proteobacteria, Acidobacteria, Bacteroidetes, and Actinobacteria. Land-use patterns were found to influence the abundance of soil functional microorganisms, with Chemoheterotrophy and Aerobic chemoheterotrophy bacteria being the dominant functional genes. The nitrogen cycle in farmland soil was significantly different from wetland and forestland soils. The differences in soil physical and chemical properties such as pH, bulk density, soil organic carbon, and total nitrogen contents were mainly responsible for the differences in microbial communities and functions.

Summary: In this study, the effects of PAHs (Phe) stress on chlorophyll fluorescence characteristics and light energy distribution parameters of Glycine soja were investigated using chlorophyll fluorescence analysis. The results showed that Phe stresses reduced the activity center and electron transfer ability of PS II, resulting in decreased light energy utilization ability. The Phe stress also affected the optical energy absorption and distribution parameters of G. soja leaves. The findings contribute to understanding the mechanism of plant photosynthesis and the environmental effects of PAHs stress.
