NiO nanoparticles with average particle size of 25 nm were successfully prepared by anodic arc plasma method. The composition, morphology, crystal microstructure, specific surface area, infrared spectra, and distribution product analyzed using X‐ray diffraction (XRD), transmission electron microscopy (TEM) the corresponding selected area (SAED), Fourier transform (FTIR) spectrum, Brunauer‐Emmett‐Teller (BET) N 2 adsorption. experiment results show that are bcc structure spherical shape well...
In the protecting inert gas, silver nanoparticles were successfully prepared by confined arc plasma method. The particle size, microstructure, and morphology of particles this process characterized via X‐ray powder diffraction (XRD), transmission electron microscopy (TEM) corresponding selected area (SAED). N 2 absorption‐desorption isotherms samples measured using static volumetric absorption analyzer, pore structure sample was calculated Barrett‐Joyner‐Halenda (BJH) academic model,...
We prepared tea tree essential oil microcapsules, and the microcapsules pullulan were coated on kraft paper to prepare an antibacterial paper. The activity, structural characterization, thermal stability of packaging then tested. found that retention rate reached 87.1% after a 70 min high-temperature treatment. minimum inhibitory concentrations S. aureus E. coli 112 mg/mL 224 mg/mL, bacteriostatic zones 17.49 mm 22.75 mm, respectively. irregular. coating was formed via hydrogen bonding,...
Double-O-tube shield tunneling has attracted increasing attention because it offers cost-efficiency in underground construction. Prediction of ground surface settlement and the variety additional stresses induced by construction is crucial to metropolises since excessive could trigger potential damage surrounding environment. The propulsion double-O-tube shields are calculated means Mindlin’s equations elasticity. characteristics analyzed with compound Gauss-Legendre integral arithmetic,...
Abstract A local time scale can be generated by steering flywheel clocks with state-of-the-art optical lattice clocks. This paper presents our simulations about the influence of clock’s operational strategies and noise characteristics on performance scale. By post-processing measured frequency difference between clock Sr1 hydrogen maser HM50 at National Institute Metrology (NIM), during modified Julian date (MJD) 59029–59059, a 0.68 ns variation referencing to TT(BIPM20) is demonstrated.
LiFePO 4 ‐Carbon (LFP/C) composites with high purity and good crystallinity were prepared by an improved environmentally benign low‐cost solvothermal method. Capping agent polyvinylpyrrolidone (PVP) polyethylene glycol (PEG‐400) showed no significant dispersive effect during the synthesis. These capping agents converted into networking carbons after annealing, which consequently charge discharge performance. It was able to deliver a initial specific capacity of 154.1 mAh g −1 for sample PVP...
In order to improve the energy saving performance of cooperative communication, a novel power allocation solution, named Half Transmission Power Allocation Solution (HTPAS), is proposed in this paper. transmission relay for forwarding packet half source. Based on efficiency analysis, HTPAS outperforms equal solution and cooperation gain, meanwhile easy be implemented. The numerical results also show that SDF more efficient than direct multi-hop when source-destination distances larger small...
