| 1 | A controllable preparation of two-dimensional cobalt oxalate-based nanostructured sheets for electrochemical energy storage显示文摘Well-defined two-dimensional(2D)cobalt oxalate(CoC_(2)O_(4)·2H_(2)O)nanosheets exhibit more excellent property than common bulk cobalt oxalate due to high specific surface areas and high-efficient transport of ion and electron.However,the delicate control of the 2D morphology of CoC_(2)O_(4)·2H_(2)O during their synthesis remains challenging.Herein,2D CoC_(2)O_(4)·2H_(2)O nanosheets(M1),grown by straightforward chemical precipitation,can be tuned from three-dimensional(3D)structure during their synthesis with no templates or capping agents.This control is obtained by rationally changing the ratio of reactants with ethylene glycol as solvent.Moreover,Co_(3)O_(4)/CoC_(2)O_(4)composites(M1-250)have been fabricated through low-temperature thermal treatment of the M1 precursor in air,which possess porous surfaces with the 2D morphology maintained.Benefiting from the porous surfaces,more redox-active sites and better electrical conductivity of Co_(3)O_(4),the constructed M1-250//AC aqueous device manifest improved kinetics of the electrochemistry process with energy density of 27.9 Wh/kg at 550.7 W/kg and good cycling stability with sustaining 73.0 m Ah/g after 5000 cycles. | Fancheng Sun Qing Li Yang Bai Guangxun Zhang Shasha Zheng Maoying Peng Xudong Chen Nuo Lin Huan Pang | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
| 2 | Numerical analysis of fiber optical parameter amplifier based on triangular photonic crystal fiber显示文摘Due to triangular photonic crystal fiber (PCF) high nonlinearity and low dispersion slope,using the condition that the different linear phase shift combination must satisfy the phase match,the expressions of gain and bandwidth for one-pump fiber-optic parametric amplifiers (1P-FOPA) based on PCF in the normal and abnormal dispersion regimes are derived respectively. Then,1P-FOPAs performance com-parison among PCF,dispersion-shifted fiber (DSF) and highly nonlinear fibers (HNLF) are carried out by numerical simulations. It is shown that the 1P-FOPA based on triangular PCF can provide higher peak gain over wider bandwidth. When the pump wavelength is at the zero-dispersion wavelength (ZDWL),about 108.7 nm single-pass gain bandwidth and 91.4 dB peak gain can be obtained; when in the normal dispersion regime and near zero-dispersion wavelength,not less than 46 nm single-pass gain bandwidth 77.1 nm away from pump can be achieved. Finally the influence of dispersion fluctuation is analyzed,and the result shows that the tolerance of the 1P-FOPA based on photonic crystal fiber is better. | SHANG maoi LIU ZengJi YUE Peng CHEN JianPing | 2009 | Science in China(Series F)2009，52，7： | 0 |
