Summary: Ni-Co/PC composite is prepared by introducing metal Co element with Ni-MOF/PC as precursor. Then a series of Ni-Co bimetal/PC composites are prepared by polyaniline coating, oxidation reaction, and vulcanization reaction. It is found that vulcanization reaction was the best path for the electromagnetic wave absorption performance of the product. The minimum reflection loss (RLmin) of NiCo2S4/PC composite reaches - 67.81 dB at the sample thickness of 2.6 mm, and the maximum effective absorption bandwidth (EAB) reaches 6.16 GHz when the sample thickness is 2.1 mm. NiCo2S4/PC composite is an ideal electromagnetic wave absorber due to its excellent electrical conductivity, rich surface, and high attenuation capability.

Summary: TiO2/C/RGO nanocomposites were successfully fabricated by introducing monolayer Ti3C2Tx (m-Ti3C2Tx) into RGO and building a porous foam structure. The m-Ti3C2Tx derived TiO2/C layer acted as a low-dielectric transition layer, optimizing the impedance matching, while the large heterogeneous interfaces composed with RGO provided more relaxation processes. The foam structure allowed easy access of EMW into the interior, resulting in scattering and refraction to prolong the loss path. The as-prepared sample exhibited high-performance EMW absorption with a minimal reflection loss of -46.48 dB (15.92 GHz) and an ultra-wide effective absorption bandwidth of 5.76 GHz, showcasing its potential in lightweight EMW absorption applications.

Summary: Run length distributions are commonly used to analyze control chart performance. However, due to the skewness of the distribution, using average run length (ARL) as a performance criterion may be misleading. To address this issue, a novel criterion based on continuous ranked probability score (CRPS) is proposed. The CRPS-based criterion is statistically consistent, informative, and robust, making it a superior metric for characterizing the run length distribution.

Summary: Understanding the dynamics of antibody immunity after heterologous SARS-CoV-2 breakthrough infection is crucial for developing next-generation vaccines. This study tracked the antibody responses in mRNA-vaccinated individuals following Omicron BA.1 breakthrough infection for up to six months. The results showed a decline in cross-reactive serum neutralizing antibody and memory B cell responses, but also indicated affinity maturation and enhanced breadth of activity. The study suggests that variant exposure drives the evolution of B cell memory and supports the development of variant-based vaccines.

Summary: The mechanisms of the photo-catalytic decarboxylative reaction between 2-phenylbutanoic acid and 1,4-dicyanobenzene (1,4-DCB) were investigated using the M06-L/ma-def2-TZVP method in the domain-decomposition COnductor-like Screening MOdel (ddCOSMO) of CH3CN. TDDFT calculations revealed the photo-excitation and electron transfer process, which matched experimental observations. Computational results showed that the R1+1,4-DCB model could undergo decarboxylation under 300 nm UV light through path c. Paths a and b demonstrated that HPO42- and K2HPO4 could successfully assist the reaction process with lower energy barriers. The findings provide valuable insights into these types of interactions and related reactions.

Summary: In this study, the poisoning resistance behaviors and mechanism of ZrCo in H2+CO2 mixed gas were systematically investigated. Even trace amounts of CO2 can strongly deteriorate hydrogenation kinetics of ZrCo, but this phenomenon can be mitigated by further increasing the inputting pressure of the mixed gas. In-situ surface reconstruction strategy by high-temperature treatment was proposed, which enhanced the CO2 poisoning tolerance of ZrCo through the formation of metallic Co nanoclusters on ZrCo surface.

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.
