Fe₂O₃/Reduced Graphene Oxide/Fe₃O₄ Composite in Situ Grown on Fe Foil for High-Performance Supercapacitors

A Fe₂O₃/reduced graphene oxide (RGO)/Fe₃O₄ nanocomposite in situ grown on Fe foil was synthesized via a simple one-step hydrothermal growth process, where the iron foil served as support, reductant of graphene oxide, Fe source of Fe₃O₄, and also the current collector of the electrode. When it directly acted as the electrode of a supercapacitor, as-synthesized Fe₂O₃/RGO/Fe₃O₄@Fe exhibited excellent electrochemical performance with a high capability of 337.5 mF/cm² at 20 mA/cm² and a superior cyclability with 2.3% capacity loss from the 600th to the 2000th cycle

Two-Dimensional Titanium Carbide/RGO Composite for High-Performance Supercapacitors

Ti₃C₂T_<i>x</i>, a 2D titanium carbide in the MXenes family, is obtained from Ti₃AlC₂ through selective etching of the Al layer. Due to its good conductivity and high volumetric capacitance, Ti₃C₂T_<i>x</i> is regarded as a promising candidate for supercapacitors. In this paper, the fabrication of Ti₃C₂T_<i>x</i>/RGO composites with different proportions of Ti₃C₂T_<i>x</i> and RGO is reported, in which RGO acts as a conductive “bridge” to connect different Ti₃C₂T_<i>x</i> blocks and a matrix to alleviate the volume change during charge/discharge process. In addition, RGO nanosheets can serve as a second nanoscale current collector and support as well for the electrode. The electrochemical performance of the as-fabricated Ti₃C₂T_<i>x</i>/RGO electrodes, characterized by CV, GCD, and EIS, are also reported. A highest specific capacitance (<i>C</i>_s) of 154.3 F/g at 2 A/g is obtained at the Ti₃C₂T_<i>x</i>: RGO weight ratio of 7:1 combined with an outstanding capacity retention (124.7 F/g) after 6000 cycles at 4 A/g

One-Step Hydrothermal Synthesis of 3D Petal-like Co₉S₈/RGO/Ni₃S₂ Composite on Nickel Foam for High-Performance Supercapacitors

Co₉S₈, Ni₃S₂, and reduced graphene oxide (RGO) were combined to construct a graphene composite with two mixed metal sulfide components. Co₉S₈/RGO/Ni₃S₂ composite films were hydrothermal-assisted synthesized on nickel foam (NF) by using a modified “active metal substrate” route in which nickel foam acted as both a substrate and Ni source for composite films. It is found that the Co₉S₈/RGO/Ni₃S₂/NF electrode exhibits superior capacitive performance with high capability (13.53 F cm^–2 at 20 mA cm^–2, i.e., 2611.9 F g^–1 at 3.9 A g^–1), excellent rate capability, and enhanced electrochemical stability, with 91.7% retention after 1000 continuous charge–discharge cycles even at a high current density of 80 mA cm^–2

Enabling a High Performance of Mesoporous α‑Fe₂O₃ Anodes by Building a Conformal Coating of Cyclized-PAN Network

The mesoporous α-Fe₂O₃/cyclized-polyacrylonitrile (C-PAN) composite was synthesized by a rapid and facile two-step method. The electrode was fabricated without conductive carbon addictive and employed as anode for lithium-ion batteries. Results demonstrate that building a conformal coating of a C-PAN network can provide a strong adhesion with active materials and contribute excellent electronic conductivity to the electrode, which can relieve the huge volume changes during a lithiation/delithiation process and accelerate the charge transfer rate. The material exhibited high reversible capacity of ca. 996 mAh g^–1 after 100 cycles at 0.2C, 773 mAh g^–1 at 1C and 655 mAh g^–1 at 2C, respectively, showing well-enhanced cycling performance and superior rate capacity, and also exhibiting significantly improved power density and energy density compared to the traditional graphite materials. Our results provide a facile and efficient way to enhance the performance of α-Fe₂O₃ anode material, which also can be applied for other oxide anode materials

DataSheet1_Curcumae Rhizoma - combined with Sparganii Rhizoma in the treatment of liver cancer: Chemical analysis using UPLC-LTQ-Orbitrap MSn, network analysis, and experimental assessment.docx

Objective:Curcumae Rhizoma–Sparganii Rhizoma (CR-SR) is a traditional botanical drug pair that can promote blood circulation, remove blood stasis, and treat tumors in clinics. The aim of the present study was to investigate the therapeutic material basis and potential mechanisms of CR-SR, CR, and SR for the treatment of liver cancer.Method: The chemical profile analyses of CR-SR, CR, and SR were performed by molecular networking and UPLC-LTQ-Orbitrap MSn. The anti-liver cancer activities of CR-SR, CR, and SR were assessed by using a zebrafish xenograft model in vivo for the first time and detected by the HepG2 cell model in vitro. Combining the network analysis and molecular docking, real-time quantitative polymerase chain reaction (RT-qPCR) experiments were undertaken to further explore the mechanisms of CR-SR, CR, and SR for the treatment of liver cancer.Results: In total, 65 components were identified in CR-SR, CR, and SR. Based on the clusters of molecular networking, a total of 12 novel diarylheptanoids were identified from CR-SR and CR. By combining our results with information from the literature, 32 sesquiterpenoids and 21 cyclic dipeptides were identified from CR-SR, CR, and SR. The anti-liver cancer activities were observed in both the drug pair and the single botanical drugs in vitro and in vivo, and the order of activity was CR-SR > CR > SR. They could downregulate the expression of proto-oncogene tyrosine-protein kinase Src (SRC), epidermal growth factor receptor (EGFR), estrogen receptor-α (ESR1), prostaglandin endoperoxide synthase 2 (PTGS2), and amyloid precursor protein (APP).Conclusion: Taken together, the present study provided an experimental basis for the therapeutic material basis and potential molecular mechanisms of CR-SR, CR, and SR. This study provided a novel insight for objective clinical treatment of liver cancer.</p
