| 1 | Microporous polythiophene(MPT)-guest complex derived magnetic metal sulfides/carbon nanocomposites for broadband electromagnetic wave absorption显示文摘Electrical and magnetic properties are two crucial factors for the designing of broadband electromagnetic wave absorption(EWA)materials.In this work,we synthesized various magnetic metal sulfides/carbon(M_(x)S_(y)/C)nanocomposites from the precursor complex of metal in microporous polythiophene(MPT),and systematically investigated their EWA properties and mechanism.The characterization results indicate that M_(x)S_(y) were determined to be Fe_(7)S_(8)/C,Co_(9)S_(8)/C and Ni_(4)S_(3)/C,respectively.It is observed that M_(x)S_(y)/C nanocomposites exhibit remarkable EWA performances,where the maximal absorption gets to-51.3 dB,and efficient absorption can be realized in 10.32-18 GHz(7.68 GHz),which is superior to most reported magnetic carbonaceous EWA composites.Beside,the efficient absorption can be tuned to cover Ku band X band,demonstrating their great potential in practical applications.Improved conductance loss,obvious polarization relaxation,and apparent eddy current loss are deemed to make the predominant contributions to the high-performance EWA.This research opens up the exploration of novel nanocomposite coupling dielectric loss and magnetic loss using MPT-metal complex precursor for EWA applications. | Yingzhi Jiao Siyao Cheng Fan Wu Jiaoyan Shi Aming Xie Xufei Zhu Wei Dong | 2022 | Journal of Materials Science & Technology2022，，5： | 1 |

| 4 | Logging while drilling electromagnetic wave responses in inclined bedding formation显示文摘For real-time inversion and fast reconstruction of formation true resistivity, the forward modeling of electromagnetic wave logging while drilling is usually based on the transversely isotropic formation model with vertical symmetry axis(VTI medium), but it only considers the horizontal and vertical resistivity. It has certain limitation during practical application. This paper presents a forward calculation method of electromagnetic wave logging while drilling in transversely isotropic(TTI) strata with inclined symmetry axis based on the Dyadic Green’s function. Anisotropic angle and azimuth are used to characterize TTI formation. The proposed algorithm is verified by numerical examples, the half-space electromagnetic wave reflection and transmission characteristics with different media are analyzed, and the necessity to use the new algorithm is pointed out. Numerical simulation also shows that there exist a critical borehole dip and critical anisotropic angle in TTI formation. Electromagnetic wave logging while drilling responses follows opposite rule before and after these two critical angles. Besides, the 'horns' at the interface are not only related to well deviation, resistivity contrast, but also related to anisotropic angle and anisotropic azimuth. | FAN Yiren HU Xufei DENG Shaogui YUAN Xiyong LI Haitao | 2019 | Petroleum Exploration and Development2019，46，4： | 0 |
| 5 | Hydrophobic and Magnetic Reduced Graphene Oxide Nanocomposite for Emulsified Oil Removal显示文摘Magnetic reduced graphene oxide(MRGO) nanocomposite was prepared by the chemical coprecipitation method and applied as adsorbent for removing emulsified oil from oily wastewater. SEM, TEM, XRD, FT-IR, VSM and other analytical methods were utilized to characterize the prepared MRGO. The adsorption performance of MRGO was evaluated under different initial adsorbate concentration, MRGO dosage, temperature, and pH value of the solution. The adsorption kinetics and isotherms were investigated. In addition, the MRGO repeatability was also tested. It was found that almost 65%of emulsified oil were removed by MRGO in the first 15 min. The MRGO adsorption capacity and efficiency for removal of adsorbate reached 335.85 mg/g and 92.52% within 60 min, respectively. The adsorption capacity reduced with an increasing MRGO dosage, while increased with the increase of emulsified oil concentration. The adsorption performance of MRGO in the alkaline environment was lower than that in the acidic environment. The adsorption data could well fit to the pseudosecondorder model. The Langmuir model could well describe the isotherm data. The MRGO adsorption capacity was still more than 236.1 mg/g at the sixth regeneration cycle. | Fan Fengtao Li Xufei Liu Fang Jiang Guofei Sui Linlin Zhao Chaocheng | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，3： | 0 |
