Abstract ：
The quasi-in situ electron backscatter diffraction method was used to investigate the microstructure and orientation evolution of Cu-45 at.% Ni alloy during the recovery process. For the first time, the "triple junction" movement theory was verified in a Cu-Ni alloy instead of in the pure metal. The "Y-junction" movement was found to be the dominant recovery mechanism in the common lamellar grains. However, this theory did not apply to grains in the area deformed by shear. Unlike the microstructure evolution, the orientation evolution was the same in the areas not deformed and deformed by shear. All the Goss orientations were swallowed by other orientations, whereas all the cube orientations swallowed other orientations. This study helped better understand the recovery process in Cu-Ni and other face-centered cubic alloys after rolling and annealing processes.

Abstract ：
Hydrogen energy, as a clean and renewable energy, has attracted much attention in recent years. Water electrolysis via the hydrogen evolution reaction at the cathode coupled with the oxygen evolution reaction at the anode is a promising method to produce hydrogen. Given the shortage of freshwater resources on the planet, the direct use of seawater as an electrolyte for hydrogen production has become a hot research topic. Direct use of seawater as the electrolyte for water electrolysis can reduce the cost of hydrogen production due to the great abundance and wide availability. In recent years, various high-efficiency electrocatalysts have made great progress in seawater splitting and have shown great potential. This review introduces the mechanisms and challenges of seawater splitting and summarizes the recent progress of various electrocatalysts used for hydrogen and oxygen evolution reaction in seawater electrolysis in recent years. Finally, the challenges and future opportunities of seawater electrolysis for hydrogen and oxygen production are presented.

Abstract ：
In this study, the effects of stress-relief annealing (SRA) on the rolled texture of nickel-based alloys were extensively analysed. Biaxially textured Ni-W alloy substrates with strong cube textures were fabricated by cold rolling and recrystallisation annealing for coated conductor applications. The results indicate that the evolution of the rolled texture, and hence the annealed cube texture, were greatly influenced by the stress-induced by deformation. The stress and rolled texture were found to be significantly correlated. X-ray diffraction and electron backscattered diffraction analyses were used to explore the effect of SRA on the cold-rolled microstructure. The stress distribution was found to be associated with the copper texture. The addition of SRA effectively eliminated stress and strengthened the copper and S textures, thereby facil-itating the formation of the final annealed cube texture. Finally, the mechanism by which stress influences the rolled texture of nickel-based alloys was elaborated in detail.(c) 2022 Elsevier B.V. All rights reserved.

Abstract ：
MgB2 superconductor pellets were synthesized through Mg gas infiltration method using nanosized-and microsized B powders. There was a marked difference in the superconducting properties of the two samples, particularly in the pinning force and dominant pinning mechanism. The microstructures of the samples were observed using HR-TEM and STEM-HAADF, and the results showed that the primary reason for the difference in the superconducting properties is the distribution of the nanosized second-phase particle MgO. Additionally, a feasible reaction model for the Mg gas infiltration method was established. Compared to the Mg liquid infil-tration method, the gas infiltration showed better penetrability ability with a small amount of residual Mg. This study presents a novel synthesis process to fabricate an MgB2 pellet with superior density and superconducting properties. This method can be used in multiple applications such as superconducting bearings, compact su-perconductor magnets, and magnetic shielding.

Abstract ：
In this study, boron powder with different particle sizes was purified by both chemical and heat treatment methods. The reduction in the particle size can improve the chemical purification with no effort on the heat treatment. The superconducting properties of the powder drastically changed even with only a partial elimination of oxygen. On the one hand, less oxygen content resulted in high T-c and J(c) values under the low magnetic field, and most importantly, a significant improvement in the superconducting connectivity (A(f) value). On the other hand, the degradation of J(c) under a high field and a change in the pinning mechanism were also found, along with decreasing oxygen. This result indicated that oxygen, probably MgO, might act as the pinning center and as an obstacle for the supercurrent in MgB2 at the same time. This work paves the way for obtaining pure oxygen-free MgB2 and understanding the real effect of oxygen in MgB2.

Abstract ：
The microstructure and texture evolution of Ni-5 at%W (Ni5W) alloy substrates were investigated by in situ tensile testing along the rolling direction (RD), transverse direction (TD), and at 45° to the RD (45°-RD), as well as by electron backscatter diffraction characterization. The tensile stress direction had a significant influence on the texture evolution. The cubic texture in the Ni-5 at%W alloy exhibited severe degradation when the tensile angle was 45°-RD. In contrast, the cubic texture was relatively stable under high deformation along the RD or TD. It was found that the slip line system in the 45°-RD specimen was the key to the contrasting behavior. The effect of the tensile testing angle on the cubic texture evolution for Ni–W substrates was investigated, and the corresponding effect on the superconducting properties of coated materials was studied.

Abstract ：
In this study, the texture evolution of CuNi alloy fabricated by rolling and annealing processes with different von Mises strains was systematically investigated by electron backscatter diffraction (EBSD). All the samples with different strains exhibited a strong cube texture after annealing at high temperatures, but the texture evolution trace was apparently affected by the strains. The most significant effect of the strain was the recrystallization nucleation of the cube texture. The distinct nucleation causes a different growth rate of the cube texture and the random texture, which causes a large temperature difference of 550-700 degrees C between the samples with different strains. This investigation allows us to better understand the texture evolution in CuNi and other FCC alloys after the rolling and annealing processes. (c) 2021 Elsevier B.V. All rights reserved.

Abstract ：
Although all the commercial REBCO tapes claim the stabilizer layer is pure Cu, the turn-to-turn contact resistance of coils wound from conductors sourced from different manufacturers may have a difference of more than an order of magnitude. The Cu layer in the REBCO tape with high contact resistance has a less dense microstructure and a higher impurity chemical compound such as oxide and carbide after systematically investigating. Such a phenomenon can reveal a possible new partial insulation strategy that the contact resistance could be increased without further co-winded with other materials by adjusting the microstructure and chemical composition in the Cu layer. Increasing the contact resistance with no co-winded with other materials will decrease the charging decay rate and not sacrifice the Je value, which has application potential in the extremely high field superconducting magnets.

Abstract ：
Among all the preparation methods, electrochemical exfoliation of graphite in neutral aqueous solution to prepare high-quality graphene is a hot research topic due to many advantages, such as high efficiency, environmental friendly, fewer defects, and convenient operation with simple equipment. In this work, the graphene was prepared by pre-intercalation assisted electrochemical exfoliation of graphite foil, in which one pre-intercalation stage was performed at the low voltage to moderately enlarge the interlayer distance of graphite foil, and then graphite electrode was electrochemically exfoliated to produce graphene nanosheets in an aqueous inorganic salt solution of (NH4)2SO4. Through comparing two pretreatment methods of graphite foil (pre-expansion with liquid nitrogen and pre-intercalation by electrochemical intercalation), the electrochemical pre-intercalation process was confirmed to avoid the serious loss of the graphite electrode during the liquid nitrogen pretreatment and facilitate electrochemical exfoliation. Meanwhile, the optimum parameters of pre-intercalation were determined. Subsequently, the effect of applied voltage on the quality of obtained graphene (such as the number of layers, defects, size, composition) during the exfoliation stage was investigated systematically, and especially the effect of applied voltage on the quality and yield of graphene was discussed in detail. The graphene nanosheets with a small number of layers (60% is less than 5 layers) were obtained through two stages of electrochemical pre-intercalation and exfoliation. The structure, morphology, and composition of the graphene were analyzed by using the XRD, SEM, TEM, AFM, and XPS. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.

Abstract ：
Using an environmentally friendly acid-alcohol system solution for electrochemical polishing of 3D printed titanium alloy, a typical U-I polarization curve was obtained, and explained the mechanism of electrochemical polishing. In this paper, the influence of electrochemical polishing factors (electrolyte temperature, polishing distance, and polishing time) on the surface roughness of Ti-6Al-4V (TC4) was studied, and optimized the process parameters to obtain a surface roughness of 0.3 mu m (1 mm x 1 mm). Electrochemical polishing can reach the level of mechanical grinding and polishing, meeting the requirements for subsequent assembly and use.
