Summary: In TiCx/Cu composites fabricated via thermal explosion reaction combined with hot press in Cu-Ti-CNTs system, the increase of TiCx content led to improved compressive strength, yield strength and wear resistance, while decreasing strain f and electrical conductivities. The 30 vol.% TiCx/Cu composites exhibited the highest performance among the 25-30 vol.% TiCx/Cu composites.

Summary: This study investigates the reaction between dicarboxylic acids and copper current collectors in battery electrodes and its influence on the microstructure and electrochemical performance. It is discovered that copper-carboxylates, not the parent acid, are the active materials. This research paves the way for using the current collector as an active component in electrode formulation, rather than just an inactive component of a battery.

Summary: A novel type II BiOCl/CAU-17 2D/2D heterostructure photocatalyst was synthesized via in situ growth of ultrathin BiOCl on the surface of CAU-17 nanorods through a solvothermal process. The 2D/2D heterostructures provide a large specific surface area and tight interfacial contact, which facilitate carrier migration. The introduction of CAU-17 enhances the light absorption ability of BiOCl/CAU-17 photocatalysts. The staggered type II heterostructure energy band alignment promotes the separation of photoexcited carriers.

Summary: Multiple factors, such as crystallographic orientation, twins, dislocation, and grain size, significantly affect the tensile properties of alloys, but identifying the dominant factor is difficult. To overcome this limitation, a combination of in situ tensile technique and electron backscattering diffraction (EBSD) was used to analyze the dominant factors affecting the tensile properties of pure nickel. This study confirmed that the grain size of pure nickel is the most significant factor influencing its tensile properties.

Summary: BiOIO3/Bi-MOF (BF-x) composites with a porous hierarchical rod-like structure were prepared by in situ growth of BiOIO3 on Bi-MOF rod-like template. BiOIO3/Bi-MOF exhibited enhanced adsorption and photodegradation efficiency of RhB and TC. The optimal BF-40 composite could degrade 99% of RhB and 78% of TC within 60 min irradiation of Xe light, and the apparent rate constant k for photodegrading RhB (TC) was approximately 8.1 (3.9) and 29.6 (12.8) times higher than that of BiOIO3 and Bi-MOF, respectively. The BiOIO3/Bi-MOF heterojunction had a larger specific surface area, improved light-harvesting ability, and boosted separation and transfer efficiency of photocarrier, which benefited to enhance the photocatalytic activity of BiOIO3/Bi-MOF heterojunction. According to the semiconductor band structure theory and the results of radicals quenching experiment, the photocarriers at the interface of BiOIO3/Bi-MOF heterojunction followed the traditional type-II migration path, and a possible type-II photocatalytic degradation mechanism was proposed. This work provided more perspective in the development of in situ growth of 2D materials on MOF with the same metal element for water treatment and other potential applications.

Summary: The content and size of in situ synthesized TiC have a significant effect on the phase compositions, microstructure, defects, and mechanical properties of Ni-based composite coatings fabricated by direct energy deposition. Increasing Ti and C elements results in changes in the phases and the volume fraction and relative diameter of TiC reinforcements. The dispersed TiC particles refine the grains and contribute to the increase in microhardness. The relative diameter of TiC also affects the volume loss and wear mechanism.

Summary: This study examines the influence of streamer and viewer behaviors on viewers' participation and financial commitment on the social live-streaming service (SLSS) Twitch.tv. The findings show that larger audiences diminish individual participation and financial commitment, while moderation may encourage more. Female streamers benefit from increased moderation, earning more in financial commitment compared to men, who attracted much smaller audiences despite streaming more frequently and for longer durations. Viewers' participation and financial commitment did not differ across streams with more content diversity.

Summary: The distribution and quantity of liquid water in snow are important for snow hydrology and avalanche forecasting. However, detecting and quantifying liquid water in snow is still a challenge. In this study, we determined the optimal mixed-phase optical property model for simulating wet snow reflectance in a controlled laboratory environment. The externally mixed model performed the best, with a 1% uncertainty in retrieving liquid water content (LWC).

Summary: The Galapagos Archipelago in the Eastern Equatorial Pacific Ocean is affected by changes in ocean currents, with the nutrient-rich Equatorial Undercurrent playing a key role in stimulating primary production. The 2015/16 El Nino event resulted in declines in phytoplankton biomass and reduced nitrate utilization in the region. Changes in protistan communities were strongly correlated with variations in subthermocline water density.

Summary: Evidence suggests that planktonic fungi play a significant role in marine food webs and biogeochemical cycles. Research on fungal dynamics in coastal to open ocean gradients shows a patchy spatial distribution and distinct niche partitioning among mycoplankton populations. The distribution patterns of mycoplankton are influenced by various factors, including temperature and potential seasonal drivers, indicating a complementary role to bacterioplankton in coastal oceans.

Summary: This study examines the community variation of Labyrinthulomycetes, a marine fungus-like protistan group, in coastal waters. The results show that the abundance and richness of Labyrinthulomycetes decrease significantly from nearshore to offshore waters, while community evenness appears to increase offshore. The community composition of Labyrinthulomycetes is significantly influenced by distance from shore, water temperature, and other environmental factors.

Summary: In dynamic coastal oceans, disturbances to microbial communities are not clearly linked to specific environmental factors, but rather result in changes in community composition. Disturbance events may lead to microbial community shifts through increased phage-associated genes, and extreme environmental events may not always fit the definition of disturbance.

Summary: By using an improved metagenomic approach, we estimated the spatial distribution and environmental regulation of ecotype-specific replication patterns in different ocean regions. Our study revealed distinct diel cycles in replication patterns within different ecotypes, as well as systematic biogeographies that differed from patterns in relative abundance. We also found that replication patterns were significantly influenced by nutrient stress and temperature, and were explained by genomic differences in nutrient transport, energy production, cell wall structure, and replication. This work adds a new dimension to our understanding of microbial niche space by examining the interactions between adaptation, environmental change, and replication patterns across ocean basins.
