Summary: This article takes advantage of the degradation characteristics of Ti3SiC2 to produce high-performance TiC matrix composites. SiC and Ti3SiC2 were homogeneously distributed in the TiC matrix through spark plasma sintering at temperatures ranging from 1400 to 1600 degrees Celsius. The resulting TiC matrix composites exhibited excellent mechanical and tribological properties.

Summary: In this study, the limited microstructural evolution of electrodeposited nanocrystalline Ni during isothermal annealing is investigated using in situ X-ray diffraction technique. The results show that the lattice contraction of Ni may be attributed to the reduction in grain boundary excess volume and the gradual improvement of lattice perfections is observed during nanostructural relaxation. Additionally, the microhardness evaluation indicates a significant hardening of nanocrystalline Ni subjected to low-temperature annealing.

Summary: The microstructure at the interface between the cocatalyst and semiconductor is crucial for the concentration of photo-induced carriers and reactants. Recent research has observed the transformation of Ti-6c-O bonds into Ti-5c-O and Ti-6c-O-Pt bonds on the TiO2-010 facet, affecting the selectivity of resulting products. These findings provide valuable insights for the development of new methodologies using conventional lab-grade equipment.

Summary: X-ray micro-computed tomography (X-ray mu-CT) is a non-destructive method for visualizing the internal microstructures of materials in 3D. It has been used in the field of food science to study the microstructures of different food materials. Small-angle X-ray scattering (SAXS) is another non-destructive method used for analyzing the structure of materials at the micro or nano level. This review discusses the applications and limitations of X-ray mu-CT and SAXS techniques in food systems.

Summary: The microstructure evolution of ultrasonic additive manufactured (UAM) zirconium during room temperature uniaxial tensile straining was evaluated using the Advanced Photon Source (APS) facility. In situ synchrotron tensile tests and wide-angle X-ray scattering (WAXS) scanning were conducted to uncover the changes in microstructure. Quantification of elastic and plastic deformation mechanisms within the strained specimens was achieved using various WAXS data analysis methods. Stress concentrations identified during plastic deformation were found to be correlated with fabrication defects, providing guidance for improving the UAM zirconium fabrication process.

Summary: In the aging process of the zinc/copper hexacyanoferrate (Zn/CuHCF) cathode, Cu dissolution activates the Fe3+/Fe2+ redox couple, leading to a progressive increase in charge/discharge voltage, while SO42- anions reversibly insert into CuHCF during charging. These structural and redox-mediated aging mechanisms are of significant importance for the development of aqueous rechargeable zinc-ion batteries.

Summary: The study shows that amorphous Zn-Sb films undergo a structural evolution during annealing, transitioning from an amorphous phase to an intermediate crystalline phase, and finally to the ZnSb phase. An intermediate phase (phase B) identified in the study is a modified beta-Zn8Sb7 phase which is accompanied by an emerging Sb impurity phase within a specific range of Sb content in the films.
