| 1 | Cu@Cu_(2)O/carbon for efficient desalination in capacitive deionization显示文摘Electrode materials with strong desalting ability is an important research direction of capacitive deionization.In this study,HKUST-1 was successfully synthesized by the solvothermal method,and MOFsderived porous carbon/Cu@Cu_(2)O composites were prepared by simple pyrolysis as cathode materials for CDI.After high-temperature pyrolysis,the Cu^(+) site with unsaturated coordination is generated,and the structure changes from micropores to the coexistence of mesoporous and micropores.The complex pore structure is conducive to strengthening ion migration and diffusion.The results show that the porous carbon/Cu@Cu_(2)O materials derived from MOFs depend on the pseudocapacitance behavior for capacitive deionization and desalination.At a voltage window of-1.2V~1.2V,a current density of 40mA/g.and 5 mmol/L NaCl,the HDC-1100 exhibited the best desalting capacity of 30.9 mg/g.HDC-1100 also has good cycle stability.After 20 cycles of adsorption and desorption,the desalting capacity almost does not decrease.Therefore,MOFs derived porous carbon/Cu@Cu_(2)O composites are expected to be an excellent choice for CDI cathode materials. | Fei Yu Haoyuan Yin Xueting Bai Junyao Pan Xiaochen Zhang Jie Ma | 2023 | Chinese Chemical Letters2023，34，12： | 0 |
| 2 | Microstructures,mechanical properties and degradability of Mg-2Gd-0.5(Cu/Ni)alloys:A comparison study显示文摘Low alloying Mg-2 Gd-0.5(Cu/Ni)alloys for sealing tools in the oil and gas industry were prepared.The differences in the effects of minor Cu and Ni additions on microstructures and properties of the Mg-2 Gd alloy were compared.The results showed that adding Ni was more effective than adding Cu in refining grain sizes,strengthening the basal fiber texture,and promoting the formation of LPSO phases,resulting in higher strength.The tensile yield strength/elongation of the Mg-2 Gd-0.5 Cu alloy,Mg-2 Gd-0.25 Cu-0.25 Ni alloy,and Mg-2 Gd-0.5 Ni alloy was 146 MPa/23.7%,175 MPa/23.1%,and 248 MPa/18.2%,respectively.The decreased elongation was attributed to the basal fiber texture and the presence of coarse LPSO phases.In terms of the corrosion rate in 3.5 wt.%NaCl solution,it rose from 112 mm y^(-1)for the Mg-2 Gd-0.5 Cu alloy to 269 mm y^(-1)for the Mg-2 Gd-0.25 Cu-0.25 Ni alloy and 490 mm y^(-1)for the Mg-2 Gd-0.5 Ni alloy,indicating that the addition of Ni instead of Cu showed a more significant promoting effect on the degradability of Mg alloys,which was related to more refined grains,the stronger basal fiber texture,and a larger amount of LPSO phases. | Shiyu Zhong Dingfei Zhang Yongqin Wang Sensen Chai Jingkai Feng Yulun Luo Jianrong Hua Qimin Dai Guangshan Hu Junyao Xu Bin Jiang Fusheng Pan | 2022 | Journal of Materials Science & Technology2022，，33： | 0 |
| 3 | Near 30%fractional bandwidth surface acoustic wave filters with novel electrode configuration显示文摘With the rapid progress of the wireless communication technique and the fast growing of the radio frequency(RF)markets,the development of wideband surface acoustic wave(SAW)filter is intensely pursued in RF front-end platforms.In this study,a novel configuration of SAW device was proposed in 15°YX-Li NbO_(3)(300 nm)/SiO_(2)(600 nm)/Si heterostructure,where the series and shunt resonator innovatively adopt Cu electrodes of different thickness to suppress the unwanted Rayleigh mode efficiently.Series and shunt resonators with clean spectrum and high electromechanical coupling coefficients over 20%were experimentally achieved under the guidance of finite element method calculation.Based on the resonator results,a ladder-type SAW filter with a very large 3-dB fractional bandwidth near 30%was successfully designed and fabricated.The minimum insertion loss of device is as small as 1.1 dB while the in-band fluctuation is less than 0.3 dB.The unprecedented wideband property of SAW device indicates that the proposed configuration is expected to become one of the solutions of wideband filter in fifth-generation mobile communication,and possess great application prospects. | Rongxuan Su Sulei Fu Zengtian Lu Junyao Shen Huiping Xu Hongqing Mao Zhibin Xu Cheng Song Fei Zeng Weibiao Wang Feng Pan | 2021 | Progress in Natural Science:Materials International2021，31，6： | 0 |
