Summary: BNNSs were efficiently prepared by magnesium borate nitridation. BNNSs/eutectic-composition Al2O3/YAG/YSZ ceramics were fabricated by hot pressing sintering. The addition of BNNSs did not alter the phase composition of BNNSs/eutectic-composition Al2O3/YAG/YSZ ceramics. The bending strength and fracture toughness of 1.5wt % BNNSs/eutectic-composition Al2O3/YAG/YSZ ceramic were increased by 19.0% and 18.9% respectively. Doped BNNSs are present at the grain boundary between two or more different grains. The toughening mechanism of BNNSs mainly involves crack deflection, BNNSs pullout, and BNNSs bridging.

Summary: The in-situ TiB2/AZ80 composite was prepared by a simple casting method and hot-rolling, which showed improved strength and toughness. The TiB2 particles can refine the grains of AZ80 alloy and promote recrystallization through PSN effect, leading to a transformation in recrystallization mode and distribution characteristics of TiB2 particle clusters. The composite sheet mainly gains strength from fine grain strengthening and thermal mismatch strengthening, while internal toughening mechanisms include texture weakening and the proliferation of more dislocations induced by the PSN effect. External toughening mechanisms are attributed to bending and deflection of cracks resulting from fiber-like particle distribution characteristics.

Summary: The addition of La element in the Mg-Gd-Zn casting alloy can fundamentally modify the microstructure, improving the strength and ductility of the alloy. The formation of Mg12La second-phase along the grain boundaries during solution treatment effectively restricts grain coarsening and increases the number density of precipitates.

Summary: This study investigates the R-curve behavior and toughening mechanisms of graphene nano-platelets (GNPs) reinforced ceramic composites. A toughening model is developed considering interface debonding, crack bridging, and pull-out of GNPs, which quantifies the contribution of different mechanisms to the improved toughness. The theoretical results match well with experimental data when GNPs are uniformly dispersed in the ceramic matrix. Prepared GNPs/ceramic composites all exhibit an increasing R-curve behavior due to the toughening mechanisms induced by GNPs, with the curve becoming steeper as GNPs content increases, indicating enhanced fracture resistance and flaw tolerance. The dominant toughening mechanism is GNPs pull-out, followed by crack bridging and interface debonding. Furthermore, the analytical model suggests that improving GNPs properties, interfacial shear strength, and reducing GNPs thickness can enhance the fracture toughness of ceramic composites.

Summary: In this paper, CNT/Mg composites with high compressive properties were prepared by using Ni-plated CNT and pure magnesium powder. The effect of grinding time for finer magnesium powder on the microstructure and properties of the final composites was studied. The results show that the uniform distribution of CNTs and strong interface bonding from the MgNi2 phase significantly improve the strength and fracture strain of the composites.

Summary: The microstructure and mechanical properties of strengthening-toughening treated 9Cr18Mo martensitic stainless steel were investigated. It was found that the size range of carbides in the steel was wide, with most of them located at the grain boundary and in the grain interior. The steel with a higher volume fraction of submicron-carbides showed a better combination of strength and impact energy. The study also found specific carbide morphologies and structural features that could be helpful in understanding the correlation between microstructure and mechanical properties of other high carbon chromium martensitic steels.

Summary: In this study, Al2O3-based ceramics were fabricated by adding zirconia sol into natural bauxite powder. The addition of zirconia sol accelerated grain boundary migration during sintering and formed numerous intracrystalline pores, leading to improved fracture toughness and flexural strength. However, the formation of intracrystalline pores was accompanied by the formation of large intercrystalline pores, which were detrimental to the mechanical properties of the materials.

Summary: Hierarchical structure composites with carbon fiber reinforced polymer (CFRP) interleaved by nanoscale core-shell rubber (CSR) and microscale short carbon fiber (SCF) were fabricated. The hierarchical structure exhibited superior interlaminar toughening efficiency. The multi-phase interleaved CFRP composite had significantly higher mode-I and mode-II critical energy release rates (GIC and GIIC) compared to unmodified samples, while maintaining the tensile properties and glass transition temperature (Tg). The study also revealed the synergistic toughening mechanisms in SCF/CSR interleaved CFRP composites.

Summary: This study investigated the influence of different temperatures and pressures on the mechanical properties of carbon fiber reinforced polyetheretherketone (CF/PEEK). The results showed that the maximum tensile strength, flexural strength, and impact strength of CF/PEEK could reach 157.3 MPa, 382.0 MPa, and 7.7 KJ/m2, respectively. The pressure-induced flow (PIF) process formed a multilayer-oriented structure, which effectively controlled crack propagation and energy dissipation, thus significantly improving the strength and toughness of CF/PEEK.

Summary: This study investigated the changes in microstructure and grain orientation of the Cu3Sn solder joint during isothermal aging at 420 degrees C. It was found that the original Cu3Sn solder joint transformed into full Cu(41)Sn(11) solder joint and eventually into full alpha(Cu) solder joint during aging. The formation of micro-voids during the conversion process resulted in lower reliability of the solder joint. The average grain sizes of interfacial phases exhibited an initial increase followed by a decrease during aging. The preferred orientations of the different phases were also examined.

Summary: Wastewater contaminated by radionuclides is a significant environmental concern that poses a threat to human health. In this study, beta-cyclodextrin modified molybdenum disulfide was investigated as an adsorbent to remove europium from aqueous solutions. The experimental results indicated that the adsorption of Europium(III) relied on pH and temperature. The Langmuir model better described the removal process, which was found to be a monolayer adsorption. The adsorption capacity of beta-CD-MoS2 for Europium(III) reached 107.1 mg/g and the adsorption process was endothermic. The surface hydroxyl groups controlled the retention of Europium(III). These findings provide important information for environmental pollution control and the elimination of Europium(III).

Summary: This study conducted a comprehensive genome-wide analysis of the bZIP gene family (RcbZIPs) in rose, revealing their phylogenetic relationships, gene structure, chromosome localizations, gene duplication, and potential functions. The expression analysis showed significant differential expression of 16 RcbZIPs in response to Botrytis cinerea infection, suggesting their candidate role in regulating rose's response to gray mold infection. Virus-induced gene silencing (VIGS) and overexpression (OE) studies demonstrated the involvement of RcbZIP17 in rose's resistance to gray mold. This study provides valuable information for further investigation into the function of the bZIP gene family in rose.

Summary: This study proposes a water resource pollution load intensity measurement based on the SWAT model, aiming to solve the problems of high measurement time-consuming, high deviation, and small area in traditional methods. The method involves building a basic database, summarizing hydrological characteristic data, designing a water pollution output coefficient model using the SWAT model, and using the comprehensive pollution index method to measure the pollution load intensity of water resources. The experimental results demonstrate that this method reduces measurement time, improves measurement accuracy, and expands the measurable area.
