Summary: Oxygen vacancies are crystal defects in eutectic ceramics fabricated by laser 3D printing. They are formed through vacancy migration mechanism and do not significantly affect the crystalline structure and microstructure of the ceramics. However, they do affect the chemical bond property and mechanical property of the as-deposited ceramics.

Summary: By adding calcium oxide to alumina, composite ceramic cores were fabricated via 3D printing to aid dissolution. The addition of 5 wt% calcia and sintering temperature were studied, showing that the formation of CaAl12O19 at high temperature enhanced the strength and properties of the sintered ceramics. The porous structure and uniform elemental distribution of the sintered composite ceramics contributed to the greater shrinkage, bulk density, and flexural strength at higher sintering temperatures.

Summary: This article provides an overview of a recent advancement in optical 3D printing, where crosslinkable materials and nanomaterial fillers are polymerized and guided to form final structures and new composites through high temperature annealing (HTA). By using ultrafast laser direct writing, 3D nano/micro-structures are defined and their precursor composition is tailored for subsequent tunability of final properties during the HTA process at temperatures between 750-1500 degrees C. This method takes advantage of efficient pyrolysis and calcination, facilitated by the large surface-to-volume ratio conditions, to enable chemical exchange between glass/ceramic and surrounding materials.

Summary: The distribution control and formation mechanism of gas inclusions in directionally solidified Al2O3-Er3Al5O12-ZrO2 eutectic ceramic rods during laser floating zone melting were explored. The presence of gas inclusions was found to be strongly influenced by the solidification rate, with intermittent formation at moderate rates and continuous formation at higher rates. Gas inclusions exhibited an elongated finger-like pattern and their volume fraction gradually increased with the solidification rate. The primary formation mechanism of gas inclusions was evaluated to be heterogeneous nucleation of gas bubbles.

Summary: Photocatalytic technology utilizing sunlight as a driving force can convert solar energy into other energy sources for storage and use. CdS, as a typical reducing semiconductor, has attracted attention in photocatalysis due to its suitable bandgap and strong reducing ability. However, the photocatalytic performance of CdS is limited by carrier recombination and photocorrosion. Therefore, CdS has been widely developed as a reducing photocatalyst in constructing S-scheme heterojunctions to overcome these limitations.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
