    Abstract The difficulty of wound healing in patients is a difficult problem that doctors in all clinical departments may encounter, and there is still no good solution. Resveratrol is a kind of natural active substance, which has anti-inflammatory, antioxidant, antibacterial, and angiogenesis promoting effects, and is a potential drug to promote wound healing. However, the clinical application of resveratrol is limited due to its low bioavailability. In this review, the molecular mechanism of resveratrol in promoting wound healing and its administration methods in wound treatment were reviewed to provide ideas for the redevelopment of resveratrol.

    Abstract In the present study, atomistic simulation reveals that the microscopic mechanism of the relaxation dynamics in amorphous materials is governed by the activating atoms that jump more than half of the average nearest neighbor distance within a given time. Based on the unsupervised machine-learning algorithm, hierarchical clustering analysis shows that the activating atoms are excited in a cooperative and avalanche-like model to form activating units. Correlation analysis suggests that large free volumes facilitate the formation of activating atoms. Interestingly, a fractal correlation is found between the number and size of the activating units, indicating that when the maturation temperature, i.e. percolation threshold, is reached the activating units form a complicated and connected body in space.

    Abstract Since the 1980s, vacuum hot rolling has been developed to fabricate the stainless steel clad plates by the Iron and Steel Institute of Japan. Herein, hot rolling is a widely used solid-state bonding process to join the carbon steel substrate and stainless steel cladding. In this paper, we provide a brief overview of the vacuum hot rolling process and effective parameters on the interface characteristics and shear strength of stainless steel clad plate. The effects of surface preparation condition, atmosphere condition, vacuum degree, rolling temperature, rolling reduction ratio, interlayer, heat treatment on the microstructure, interface characteristics and mechanical properties of stainless steel clad plate have been analyzed in detail. It is shown that the interface transition zone is formed due to the carbon diffusion, and the strong interface bonding is attributed to the sufficient alloy elements diffusion of Fe, Cr and Ni. Moreover, the interface shear strength and toughness are also affected by interfacial precipitation phase and multiple oxides. Finally, the present work concluded the bonding mechanism of hot-rolled stainless steel clad based on the oxide film theory, diffusion theory, recrystallization theory and three stage theory.

    Abstract Objective: To investigate the effectiveness of a new health education pathway for echinococcosis control among primary school students in regions highly prevalent for echinococcosis in China.
    Methods: Six primary schools were randomly selected from echinococcosis hyper-endemic regions, with 13 classes assigned to the intervention group and 9 to the control group, and all students in these 21 classes were recruited as the study subjects. Echinococcosis health education was performed through the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices in the intervention group, while routine health education was given in the control group. A questionnaire survey was performed to assess the score of echinococcosis control knowledge (including theoretical knowledge score and mean daily practical capability score) before and after the health education interventions to evaluate the effectiveness of this new health education pathway for echinococcosis control.
    Results: The mean score of echinococcosis control knowledge was 68.86 ± 18.70 points at baseline, with the mean theoretical knowledge score of 40.97 ± 10.75 points, and the mean daily practical capability score of 27.89 ± 12.50 points. Clustering analysis showed three types of populations, including "unsatisfactory", "learn and apply creatively", and "rote learning", which accounted for 24.62% (240/975), 45.74% (446/975) and 29.64% (289/975), respectively. The mean score of echinococcosis control knowledge was 81.08 ± 18.15 points in the intervention group during the final assessment, with the mean theoretical knowledge score of 43.65 ± 9.40 points, and the mean daily practical capability score of 37.43 ± 12.22 points, and both were significantly higher relative to baseline (
    Conclusions: The awareness of echinococcosis control knowledge is fair among primary school students in echinococcosis hyper-endemic regions; however, the capability of combining theoretical learning and practices requires to be improved. The health education mode based on the pathway of assessing the current status-strengthening the building of teaching resources-focusing on practices seems to remarkably improve the understanding of echinococcosis control knowledge among primary school students in echinococcosis hyper-endemic regions.

    Abstract Based on the newly constructed n-body potential of Ni-Ti-Mo system, Molecular Dynamics and Monte Carlo simulations predict an energetically favored glass formation region and an optimal composition sub-region with the highest glass-forming ability. In order to compare the producing techniques between liquid melt quenching (LMQ) and solid-state amorphization (SSA), inherent hierarchical structure and its effect on mechanical property were clarified via atomistic simulations. It is revealed that both producing techniques exhibit no pronounced differences in the local atomic structure and mechanical behavior, while the LMQ method makes a relatively more ordered structure and a higher intrinsic strength. Meanwhile, it is found that the dominant short-order clusters of Ni-Ti-Mo metallic glasses obtained by LMQ and SSA are similar. By analyzing the structural evolution upon uniaxial tensile deformation, it is concluded that the gradual collapse of the spatial structure network is intimately correlated to the mechanical response of metallic glasses and acts as a structural signature of the initiation and propagation of shear bands.

    Abstract Issues related to the glass formation of ternary Mg–Al–Cu metallic glass are investigated by thermodynamic calculations and an atomistic approach. Based on the extended Miedema model, thermodynamic calculations show that Mg–Al–Cu metallic glasses are favored over a large composition range, and that the sub-region of MgxAlyCu1−x−y (x = 20–30; y = 30–40; 1 − x − y = 35–45) shows a better glass formation ability than the other compositions. Then, a realistic interatomic potential was constructed for the Mg–Al–Cu system and applied in Monte Carlo simulations to predict the favored composition at the atomic level, and even pinpoint the optimized composition. The simulation not only predicted a quadrilateral region, within which Mg–Al–Cu metallic glass formation is energetically favored, but also pinpointed an optimized sub-region within which the amorphization driving force (ADF), i.e. the energy difference between the solid solution and the disordered state, is larger than that outside. The predictions of the atomistic approach are consistent with the thermodynamic calculation. The simulations not only provided predictions for producing Mg–Al–Cu metallic glasses, but also revealed the physical origin of the crystal–amorphous transition, which could be of great help for designing ternary glass formers.

    Abstract With the aid of ab initio calculations, a realistic interatomic potential was constructed for the Mg-Cu-Y ternary system under the proposed formalism of smoothed and long-range second-moment approximation of tight-binding. Taking the potential as the starting base, an atomistic computation/simulation route was developed for designing favored and optimized compositions for Mg-Cu-Y metallic glass formation. Simulations revealed that the physical origin of metallic glass formation is the collapse of crystalline lattice when solute concentration exceeds a critical value, thus leading to predict a hexagonal region in the Mg-Cu-Y composition triangle, within which metallic glass formation is energetically favored. It is proposed that the hexagonal region can be defined as the intrinsic glass formation region, or quantitative glass formation ability of the system. Inside the hexagonal region, the driving force for formation of each specific glassy alloy was further calculated and correlated with its forming ability in practice. Calculations pinpointed the optimized stoichiometry in the Mg-Cu-Y system to be Mg64Cu16Y20, at which the formation driving force reaches its maximum, suggesting that metallic glasses designed to have compositions around Mg64Cu16Y20 are most stable or easiest to obtain. The predictions derived directly from the atomistic simulations are supported by experimental observations reported so far in the literature. Furthermore, Honeycutt-Anderson analysis indicated that pentagonal bipyramids (although not aggregating to form icosahedra) dominate in the local structure of the Mg-Cu-Y metallic glasses. A microscopic picture of the medium-range packing can then be described as an extended network of the pentagonal bipyramids, entangled with the fourfold and sixfold disclination lines, jointly fulfilling the space of the metallic glasses.

    Abstract For the Mg–Ni–Y system, a typical Mg-based bulk metallic glass forming system, glass formation compositions are first predicted by thermodynamic calculations based on the extended Miedema’s model, suggesting that metallic glasses in the system are favored over a large composition range. Assisted by ab initio calculations, a realistic Mg–Ni–Y n-body potential is then constructed under a proposed modified tight-binding scheme. Based on the potential, an atomistic modeling scheme is further formulated for designing the favored, and even pinpointing the optimized, compositions at the atomic level. A hexagonal glass formation region is located for the Mg–Ni–Y system, reflecting the possible compositions energetically favoring metallic glass formation. An optimized stoichiometry sub-region is further pinpointed, within which the driving force for glass formation is prominently larger than that outside. The present study evaluates glass formation in the Mg–Ni–Y system from two different perspectives, and the results have implications for the entire family of Mg-based systems. The prediction schemes could be of great help for guiding the composition design of ternary glass formers.
