With the rapid consumption of fossil fuels and massive emission pollutants, multifunctional materials are upgrading trend automotive aerospace structures. As a promising structural energy storage device, specific capacitance carbon-fiber-based supercapacitor is greatly limited as result low surface area carbon fiber electrodes. In this work, we prepared high-performance supercapacitors that consisted in situ ex activated (AC)-coated electrodes, glass separator, bicontinuous electrolyte. The...
In this work, Fe-decorated nitrogen-doped carbon nanospheres are prepared for electrochemical monitoring of acetaminophen. Via a direct pyrolysis the melamine-formaldehyde resin spheres, well-distributed Fe-NC spheres were obtained. The as-prepared possesses enhanced catalysis towards redox acetaminophen abundant active sites and high-speed charge transfer. effect loading Fe species on sensing is investigated in detail. synergistic nitrogen doping along with above-mentioned properties taken...
In this work, the glucose nanocarbon spheres (GC) were in situ decorated on surface of lamellar peanut shell biochar (PSAC) to construct self-modified conductive function unit biomass (PSAC@GC). The effects PSAC@GC at different carbonization temperatures conductivity, antistatic properties, and thermal stability epoxy composites investigated. This unique structure not only improves dispersion GC nanospheres resin, but larger carbon framework PSAC also contributed forming a continuous...
This paper describes a strategy for preparing free-standing reduced graphene oxide@Si nanoparticles (rGO@Si NPs) composite membranes. Graphene oxide (GO) was and self-assembled synchronously with of silicon (Si on metal surface the film subsequently used in lithium-ion battery (LIB). work several important novel aspects reported technology. Firstly, membrane has flexible self-supporting structure, allowing it to function as an anode material without requiring binders current collectors....
Herein, we report a hierarchical structure formed by wrinkled reduced graphene oxide (rGO) sheets-wrapped carbon fiber via facile and efficient electrostatic self-assembly method subsequent annealing treatment. For this material, the Weibull scale parameter is 4.77[Formula: see text]GPa. After 100 cycles, rGO@CF retains 91% of its second charge capacity at 50[Formula: text]mA ⋅g −1 , corresponding to fading only 0.09% per cycle. Thus, structural anode material exhibits enhanced capacity,...
Large-scale wind power centralized integration into grid via long transmission lines is the major way to use energy in China. However, cascading trip faults area brings a great new challenge for secure operation of grid. Due complexity SCOPF, this paper proposes N-1 sensitivity based method coordinately control active and reactive prevent fault. The center aims minimize curtailment guarantees both normal operation. This strategy also suppresses farms' voltage fluctuation minimizes regulation...
As a kind of new lubricant additive, Nano SiO 2 particles exist in the form particle cluster suspensions.The objective present study is to put forward lubrication behavior clusters water-based cold rolling liquid through experiments Q235 steel.PH values were adjusted find out best degree dispersion.Samples investigated micro surface observation and elemental analysis.It found that strengthened spreading property film enhanced stability by splitting into smaller under rapid increased stress...
