| 2 | Synthesis and characterization of MoS2/Fe@Fe3O4 nanocomposites exhibiting enhanced microwave absorption performance at normal and oblique incidences显示文摘Herein,we attempted to prepare MoS2/Fe@Fe3O4 nanocomposites capable of strongly absorbing broadband incident electromagnetic(EM)radiation and probed the effects of their composition on complex permittivity and permeability at 2-18 GHz.Calculations of normal-incidence reflection losses(RLs)based on EM parameters revealed that the Fe@Fe3O4 to MoS2 mass ratio strongly influenced the absorption peak intensity and bandwidth.Specifically,an RL peak of-31.8 dB@l5.3 GHz and a bandwidth(RL<-lOdB)of4.8 GHz(13.2-18 GHz)were achieved at a thickness of 1.52 mm and a Fe@Fe3O4 to M0S2 mass ratio of 60:40.Further,RL and bandwidth were investigated for oblique incidence,in which case two kinds of EM waves(TE-electric field perpendicular to plane of incidence;TM-electric field in the plane of incidence)were considered.The absorption peaks of TE and TM waves did not exceed-2 0 dB when the incidence angle increased to 3 0,and the bandwidth(R L<-10 dB)reached 4.2 GHz(TE wave)and 4.0 GHz(TM wave)when this angle was further increased to 40.0°and 50.4,respectively.Finally,the mechanism of microwave absorption was discussed in detail. | Peng Wang Junming Zhang Guowu Wang Benfang Duan Donglin He Tao Wang Fashen Li | 2019 | Journal of Materials Science & Technology2019，35，9： | 2 |
| 3 | Recent progress in functionalized layered double hydroxides and their application in efficient electrocatalytic water oxidation显示文摘Layered double hydroxides (LDHs), a class of anionic clays consisting of brucite-like host layers and interlayer anions, have been widely investigated in the last decade due to their promising applications in many areas such as catalysis, ion separation and adsorption. Owing to the highly tunable compositi on and uniform distribution of metal cations in the brucite-like layers, as well as the facile exchangeability of intercalated anions, LDHs can be modified and functionalized to form various nanostructures/composites through versatile processes such as anion intercalation and exfoliation, decoration of nanoparticles, selfassembly with other two-dimensional (2D) materials, and controlled growth on conductive supports (e.g., nanowire arrays, nano tubes, 3D foams). In this article, we briefly review the recent advances on both the LDH nano structures and functionalized composites toward the applications in energy conversion, especially for water oxidation. | Xiaolong Deng Jinzhao Huang Hao Wan Fashen Chen Yifan Lin Xijin Xu Renzhi Ma Takayoshi Sasaki | 2019 | Journal of Energy Chemistry2019，28，5： | 2 |
| 4 | Synthesis and relaxivity of polycarboxylic hydrazone rare earth complexes——Relaxivity of α-oxo-pentanedioic acid benzoyl hydrazone Gd-complexes显示文摘Synthesis of ligand, α-oxo-pentanedioic acid benzoyl hydrazone (H2LPB), and its six rare earth (La, Pr, Nd, Sm, Gd and Er) complexes are reported. The composition and the properties of the complexes were characterized by element analysis, thermal analysis, UV, IR and H NMR spectra. Besides, relaxivity (R1) of Gd-complex has been determined by INVREC.Au program, using inversion recovery pulse sequences, R1=8.05 mmol ·L-1 · s-1. The acute toxicity of Gd-complex in animal has also been tested, and the median lethal dose (LD50) is equal to (468.2±30) mg/kg. | Zhengyin Yang Fashen Li Li Yang Rudong Yang | 2000 | Chinese Science Bulletin2000，45，20： | 2 |

| 14 | Preparation of Ce_(2)Fe_(17)N_(3-δ)@FePO_(4) composite with excellent microwave absorption performance by reduction-diffusion(R/D)and phosphating processes显示文摘Ce_(2)Fe_(17)N_(3-δ)composites have always been focused on electromagnetic wave(EMW)absorbing field because of their high resonance frequency and magnetic loss.However,the issues of preparation cost and impedance mismatching still limit the industrial conversion and practical application of Ce_(2)Fe_(17)N_(3-δ)composites.In this work,the composites of Ce_(2)Fe_(17)N_(3-δ)with a phosphate insulation layer(Ce_(2)Fe_(17)N_(3-δ)@FePO_(4))were prepared by a newly-developed reduction-diffusion(R/D)and phosphating processes using CeO_(2) as raw mate rials,and their microwave absorption properties were investigated.The composite filled with 30 vol%of the Ce_(2)Fe_(17)N_(3-δ)@FePO_(4) has a minimum reflection loss(RL)of-63 dB and an effective absorption bandwidth(EBW,RL<-10 dB)of 3.83 GHz at a thickness of 1.25 mm in the X-band,and the EBW reaches 5 GHz under 0.98 mm in the Ku-band.This study demonstrates that the Ce_(2)Fe_(17)N_(3-δ)@FePO_(4) composite s with low cost and excellent microwave absorption properties have a significant potential for industrial production and practical applications. | Zuying Zheng Yunguo Ma Hao Wang Peng Wu Hongbo Hao Liang Qiao Tao Wang Zheng Yang Fashen Li | 2023 | Journal of Rare Earths2023，41，11： | 1 |
