Summary: By inducing partial phosphating on NiGa-LDH, the derived Ni2P/NiGa2O4/NiGa-LDH structure effectively improves the capacitance and charge/discharge speed of supercapacitors, while preserving the layered structure of LDHs and reducing the charge transfer impedance. Additionally, the hybrid supercapacitor (HSCs) composed of Co3O4-C negative electrode and Ni2P/NiGa2O4/NiGa-LDH positive electrode demonstrates excellent energy density and long-term stability under high power density.

Summary: The role of functional groups in the adsorption process of functionalized layered double hydroxide (LDH) to target pollutants was investigated. Functionalized NiFe-LDH with 2 mercaptoethane sulfonic acid (MS) as an intercalation modifier was prepared. Molecular dynamics simulation revealed the interfacial interaction between the functional groups and the NiFe-LDH surface. The results showed that the sulfonic acid group self-assembled electrostatically with the LDH laminate, while the sulfhydryl group complexed heavy metal ions. The adsorption experiments demonstrated significantly improved adsorption performance of the modified NiFe-LDH for Cd2+, Mn2+, and Co2+ ions. The molecular dynamics simulation and wavefunction analysis provided insights into the mechanism of enhanced adsorption capacity by the functional groups.

Summary: This study investigates the adsorption capacities of ten types of pristine biochars and biochars modified with LDH for mixed heavy metal ions (Cu2+, Co2+, Pb2+) and phosphate ions. The LDH-biochars exhibit significantly higher adsorption capacities compared to pristine biochars. Part of the Mg and Al ions are released during adsorption but account for less than 7.2% of the adsorbed ions. Pristine biochars have specific adsorption sites for different metal ions, while LDH interacts with biochar's functional groups to enhance the adsorption capacity.

Summary: This study synthesized a novel corn straw biochar-loaded calcium-iron layered double hydroxide composite (CaFe-LDH@CSB) and applied it as a remediation adsorbent for heavy metals (HMs) in both water and soil environments. The adsorption mechanism of CaFe-LDH@CSB in water involved a chemical endothermic adsorption process dominated by various interactions. The maximum adsorption capacity for Cd(II), Pb(II), Zn(II), and Cu(II) in water was 24.58, 240.96, 57.57, and 39.35 mg g-1, respectively. Application of CaFe-LDH@CSB in HM-contaminated soil treatment also helped increase soil pH.

Summary: This study investigated the efficiency of a new composite material, consisting of layered double hydroxide (LDH) of ZnMgAl and rice husk biochar (RHB), for removing Cu(II) and Pb(II) ions from synthetic wastewater. The scanning electron microscope images revealed fine crystalline LDH particles on the rough surface of RHB, confirming the successful formation of the LDH/RHB composite adsorbent. The optimized dosage of LDH/RHB adsorbent at 0.4 g L-1 resulted in maximum adsorption capacities of 117 mg g-1 for Cu2+ and 124 mg g-1 for Pb2+, with removal efficiencies of nearly 94% and 99% respectively.

Summary: Reconstructing miniaturized peptides to mimic specific protein functions is appealing but challenging. In this study, we propose a practical approach to construct a mimetic peptide of redox-sensitive green fluorescent protein-2 (roGFP2) by rethreading aromatic residues adjacent to the chromophore fragment. By fine-tuning the residues, we designed a mini tetrapeptide (Cys-Phe-Phe-His) that acts as a hydrogen peroxide sensor using ratiometric fluorescence. The roGFP2 mimetic tetrapeptide, with its assembly-induced emissions, is biocompatible, photostable, and exhibits competitive fluorescent properties compared to roGFP2. We demonstrated the ability of the ratiometric tetrapeptide to sense hydrogen peroxide in acidic chambers, providing a promising approach for artificially designing miniaturized peptides with desired functions.

Summary: The release of phenolic compounds and their bioactivity during digestion and fermentation of mulberry leaves were investigated. The bioavailability of total phenolics and flavonoids in fermented mulberry leaves (F-MLs) were 10.14 +/- 1.81% and 6.66 +/- 0.55%, respectively. There was no significant difference in the inhibitory activity of alpha-glucosidase during gastrointestinal digestion. F-MLs exhibited higher phenolic bioaccessibility, antioxidant activities, and short-chain fatty acid production, making them a promising candidate for health food supplements.

Summary: Hexanal has antimicrobial activity against Vibrioparahaemolyticus, but its antibacterial effect and mechanism have not been fully studied. This research used proteomics and metabolomics to investigate the mechanism of action of hexanal. The results showed that hexanal treatment reduced ATP concentration, increased membrane permeability, and disrupted cell morphology and ultrastructure of V. parahaemolyticus. Proteomics and metabolomics analysis identified numerous differentially expressed proteins and metabolites involved in various biological pathways. Bioinformatics analysis revealed that hexanal damaged cell membranes, inhibited nucleotide metabolism, and disrupted carbohydrate and TCA cycles, leading to growth inhibition and death of V. parahaemolyticus. This study provides valuable insights into the antibacterial mechanism of hexanal and its potential application in the seafood industry.

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.
