    Abstract: Shaoyao-Gancao Tang (SGT) is one of the most frequently used compound formulas in the treatment of pain-related diseases in the medical practice of traditional Chinese medicine (TCM). To investigate the anti-inflammatory and antinociceptive effects, as well as to uncover the molecular mechanism of SGT, the rat pain model of arthritis was experimentally induced by single unilateral injection of rats’ left hind paw with Freund’s complete adjuvant (FCA). SGT was orally administered to the rats daily at three doses individually for a period of 16 days post-model induction. Swollen degrees and pain thresholds of the rats in different groups were measured for evaluation of the anti-inflammatory and anti-nociceptive effects of SGT. Furthermore, the mRNA and protein expression levels of transient receptor potential ion channel protein vanilloid receptor 1 (TRPV1) channel as well as its calcium-mediating function in the isolated DRG neurons were further detected to provide indexes for exploration of the molecular mechanisms mediating anti-arthritic activities of SGT. As a result, FCA injection induced significant allodynia, inflammation and edema, accompanied by a significant increase in both expression and calcium-mediating function of the TRPV1 channel. Pharmacologically, oral administration of SGT at a high or middle dose demonstrated a significant relief from the above-mentioned pathological conditions in a dose-dependent manner. Simultaneously the mRNA and protein expressional levels of TRPV1 channel, as well as its calcium-mediating function, were down-regulated greatly. These findings suggest that SGT possesses a significant analgesic and anti-inflammatory effect on arthritis rats; its therapeutic activities might be achieved through reversing the elevated expression and function of TRPV1 channel evoked by FCA.

    Abstract: Corn cob-like Fe 3 O 4 @Ni 3 S 2 nanocomposites was synthesized through a facile two-step hydrothermal process. The precursor was obtained by a facile calcination of a Fe-MOF template, then, nickel sulfide coated on iron oxide composites were synthesized using a hydrothermal method. In addition, the fabricated Fe 3 O 4 @Ni 3 S 2 electrode revealed a great electrical performances with a maximum specific capacitance of 1200[Formula: see text]F[Formula: see text] g[Formula: see text] at 1[Formula: see text] A[Formula: see text]g[Formula: see text] , a capacitance retention of 83% could be observed after 1000 cycles at a great charge–discharge current density of 5[Formula: see text]A[Formula: see text] g[Formula: see text]. We believed that the excellent performance might be ascribed to the synergistic effect between the Fe 3 O 4 and Ni 3 S 2 . Thus, the results demonstrate the corn cob-like Fe 3 O 4 @Ni 3 S 2 composite is prominent candidate in the field of supercapacitor applications.

    Abstract: A solid-state energy storage device has been fabricated using FeCo-selenide nanosheet arrays as positive electrode and Fe 2 O 3 nanorod as negative electrode. As an electrode material, the ternary FeCo-selenide nanosheet arrays supported by Ni foam show a highest specific capacitance of 978 F/g (specific capacity of 163[Formula: see text]mAh/g) at 1 A/g and a superior cycle behavior of 81.2% are obtained after 5000 cycles at current density of 4 A/g. The asymmetric supercapacitor achieves the maximum energy density of 34.6[Formula: see text] W[Formula: see text]h/kg at the power density of 759.6[Formula: see text] W/kg. Furthermore, the superior cycling stability with 83% retention of initial capacitance after 5000 cycles further verify the practical applications of FeCo-selenide//Fe 2 O 3 asymmetric supercapacitor. Meanwhile, the LED bulb and the light board of “CUMT” are lighted by connecting several capacitors to form a series circuit.

    Abstract: The vibration-based identification method has long been used as an alternative to mechanical tests for material characterization. Its non-destructive nature, high efficiency in parameter identification of anisotropic materials and its ability to achieve structure-level homogenization make it very attractive for both academic community and industry. Due to the absence of explicit mapping from the result of vibration test to elastic constants, conventional vibration-based identification approaches generally rely on the minimization of a cost function built on modal properties or Frequency Response Function (FRF) curve. In this paper, a direct relation from FRFs to mechanical properties is established by deep neural network, which offers a new perspective to solve the inverse identification problem. Specifically, this mapping is approximately built with Multilayer Perceptrons (MLPs) and the network’s weights are learned from massive training data. The training data-i.e., the FRF curves, is generated by a finite element model whose input parameters are selected by Latin Hypercube Sampling (LHS). After training, the obtained model is validated by dataset unseen during training process and will be further used to predict mechanical properties of materials from FRFs obtained by vibration test. The effectiveness and efficiency of the developed method are demonstrated on the case study of an aluminum plate. Both the Young’s modulus and Poisson’s ratio are retrieved with high accuracy.

    Abstract: A series of nickel sulfides derived from the hexagonal Ni-MOF are vulcanized through adjusting the hydrothermal time and the thiourea concentration. Among all the obtained nickel sulfides, one sample Ni-S2-3, which inherits the Ni-MOF’s morphology, shows the best electrochemical performance with a remarkable specific capacitance of 1128[Formula: see text]Fg[Formula: see text] at 1[Formula: see text]Ag[Formula: see text] , a rate capacitance of 50% and a long cycle life of 74% retention after 5000 cycles. Furthermore, the asymmetrical supercapacitors (SCs) based on Ni-S2-3//AC exhibit a good supercapacitive performance with a maximum power density of 16.3[Formula: see text]Wh kg[Formula: see text] at a power density of 800[Formula: see text]Wkg[Formula: see text] . All these results indicate that vulcanizing Ni-MOF is an effective way to fabricate a superior electrode material with excellent electrochemical performance for SCs.

    Abstract: The interconnected three-dimensional Ni–Co–S nanosheets were successfully deposited on ZnO nanorods by a one-step potentiostatic electrodeposition. The Ni–Co–S nanosheets provide a large electrode/electrolyte interfacial area which has adequate electroactive sites for redox reactions. Electrochemical characterization of the ZnO@Ni–Co–S core–shell nanorods presents high specifc capacitance (1302.5[Formula: see text]F/g and 1085[Formula: see text]F/g at a current density of 1 A/g and 20 A/g), excellent rate capabilities (83.3% retention at 20[Formula: see text] A/g) and great cycling stability (65% retention after 5000 cycles at a current density of 30[Formula: see text]A/g). The outstanding electrochemical performance of the as-prepared electrode material also can be ascribed to these reasons that the special structure improved electrical conductivity and allowed the fast diffusion of electrolyte ions.

    Abstract: With the virtual synchronous generator (VSG) technology gradually becoming an emerging technology for new energy consumption, its introduction has solved the problems of weak support and weak anti-interference of traditional new energy stations. However, the practice shows that the grid-connected characteristics of VSG limit its large-scale utilization, and there is little research on the interaction between VSG and a multi-machine system. In this paper, small signal models and time domain simulation models of each link of a photovoltaic(PV) power station with the PV virtual synchronous generator (PV-VSG) are first conducted, and then the influence of the grid-connected PV power station with the PV-VSG on the low-frequency oscillation of power system and its interaction mechanism with the multi-machine system are qualitatively obtained based on the small signal analysis method and prony analysis method from two dimensions of frequency domain and time domain, respectively. The analysis and simulation show that the PV power station based on VSG technology affects the dynamic characteristics of the system by changing the electromagnetic torque of each synchronous generator. Unreasonable operating conditions and parameter settings will aggravate the phenomenon of low-frequency oscillation of the system. Before the grid connection of PV power station, the operating parameters shall be reasonably set to ensure their safe and stable grid connection.

    Abstract: In this study, a simple one-step hydrothermal method was developed to prepare a novel hierarchical CoNi 2 S 4 nanostructure similar to rambutan fruit. The surface microstructural study clearly visualized that the rambutan-like CoNi 2 S 4 consists of nanorods grown directly on the surface of spherical core structures. The close attachment of the nanorods to the spheres increased the active areas of the electrode, which facilitates efficient charge transport from the nanorods to the spherical core structure. CoNi 2 S 4 with a rambutan-like hierarchical structure showed an excellent specific capacitance of 944[Formula: see text]F[Formula: see text] g[Formula: see text] at 1[Formula: see text] A[Formula: see text] g[Formula: see text], considerable rate capacitance (75.6% retention at 10[Formula: see text] A[Formula: see text]g[Formula: see text] ) and excellent cycling life (91.1% retention after 5000 circulations) in the three-electrode system. Besides, the assembled hybrid supercapacitor based on CoNi 2 S 4 and reduced graphene oxide exhibited a high specific energy density of 23.58[Formula: see text]Wh[Formula: see text] kg[Formula: see text] at the power density of 800[Formula: see text] W[Formula: see text]kg[Formula: see text] .
