Summary: The study examines the properties of composite fluoropolymer-containing coatings formed by the cold spray method on constructional steel. Different methods of protective coating formation are proposed. The results show that including super-dispersed polytetrafluoroethylene (SPTFE) in the coating enhances its corrosion resistance. Electrochemical analysis further reveals that samples treated with SPTFE have lower corrosion current density and higher impedance modulus compared to samples with cold-sprayed SPTFE. The findings suggest that cold-sprayed polymer-containing coatings effectively improve the corrosion and wear resistivity of the material.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear properties.

Summary: Piezoelectric silicon carbide (SiC) has been considered for various applications due to its superior properties. However, its brittleness and unsatisfactory piezoelectric response have limited its use. In this study, PVDF/6H-SiC composite fiber films were fabricated and used for assembling high-performance energy harvesters and sensors. The results showed significant improvements in piezoelectric response and sensitivity compared to pure PVDF films. First-principles calculation and finite element analysis confirmed the effect of SiC nanoparticles on the composite film.

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: The bainite transformation in medium Mn steels has been experimentally and theoretically studied, and it has been found that the transformation kinetics is slow. However, the introduction of dislocations can significantly accelerate the transformation rate. A new "carbon depletion mechanism" is proposed to explain the role of dislocations in the acceleration of bainite transformation, and a physical model is developed to quantitatively understand the kinetics of bainite transformation.

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.
