<P>A promising anode material for lithium-ion batteries (LIBs) consisting of Sb2Se3 nanorods and reduced graphene oxide (rGO) sheets has been prepared by an effective solvothermal approach. The synergetic effect between Sb2Se3 nanorods and rGO matrix provides not only high conductivity paths and strong electron contact interface, but also alleviates the volume change of Sb2Se3 nanorods, resulting in excellent lithium-storage performance. When tested as an anode material for LIBs, a high capacity of 868.30 mAh g(-1) can be retained after 100 cycles at 200 mA g(-1). Even at 2000 mA g(-1), a satisfactory capacity of 430.40 mAh g(-1) after long 550 cycles can be delivered. Ex situ X-ray diffraction study suggests that the Sb2Se3/rGO composite follows the combined Li+ intercalation, conversion reaction and alloying reaction mechanism. These features suggest the Sb2Se3/rGO composite a viable choice for application as an anode material in high-performance LIBs. (C) 2017 The Electrochemical Society. All rights reserved.</P>

In order to research the variation characteristics and infl uencing factors of the rotor surface eddy current loss during the nuclear power half-speed turbo-generator asymmetric operation, the harmonics characteristics of eddy current generated by stator negative sequence current on the rotor surface are derived by analytical method, and the harmonic characteristics of excitation current generated by stator negative sequence current on excitation winding are derived. On the basis, the harmonic current characteristics of stator winding caused by the harmonic component of excitation current are derived. Furthermore, the eddy current characteristics on the rotor surface caused by the harmonic current in the stator current are derived. At the same time, the infl uence factors and distribution characteristics of eddy current and eddy current loss of rotor damping strip and slot wedge are given. On this basis, taking a 1407MVA nuclear power half-speed turbo-generator as an example, the fi eld-circuit coupled model is established. The normal and asymmetrical operation of the generator is simulated. Through the comparison and analysis between simulation results and theoretical derivation results, the correctness of theoretical derivation is verifi ed. A theoretical reference for researching mechanism and infl uencing factors of rotor surface loss during nuclear power half-speed turbo-generator asymmetrical operation is proved.

BACKGROUND: As a contour-supporting material, the cartilage has a significant application value in plastic surgery. Since the development of hydrogel scaffolds with sufficient biomechanical strength and high biocompatibility, cell-laden hydrogels have been widely studied for application in cartilage bioengineering. This systematic review summarizes the latest research on engineered cartilage constructed using cell-laden hydrogel scaffolds in plastic surgery. METHODS: A systematic review was performed by searching the PubMed and Web of Science databases using selected keywords and Medical Subject Headings search terms. RESULTS: Forty-two studies were identified based on the search criteria. After full-text screening for inclusion and exclusion criteria, 18 studies were included. Data collected from each study included culturing form, seed cell types and sources, concentration of cells and gels, scaffold materials and bio-printing structures, and biomechanical properties of cartilage constructs. These cell-laden hydrogel scaffolds were reported to show some feasibility of cartilage engineering, including better cell proliferation, enhanced deposition of glycosaminoglycans and collagen type II in the extracellular matrix, and better biomechanical properties close to the natural state. CONCLUSION: Cell-laden hydrogels have been widely used in cartilage bioengineering research. Through 3-dimensional (3D) printing, the cell-laden hydrogel can form a bionic contour structure. Extracellular matrix expression was observed in vivo and in vitro, and the elastic modulus was reported to be similar to that of natural cartilage. The future direction of cartilage tissue engineering in plastic surgery involves the use of novel hydrogel materials and more advanced 3D printing technology combined with biochemistry and biomechanical stimulation.
