| 1 | Rational design of MoS_(2) nanosheets decorated on mesoporous hollow carbon spheres as a dual-functional accelerator in sulfur cathode for advanced pouch-type Li–S batteries显示文摘Developing sulfur cathodes with high catalytic activity on accelerating the sluggish redox kinetics of lithium polysulfides(Li PSs) and unveiling their mechanisms are pivotal for advanced lithium–sulfur(Li–S)batteries. Herein, MoS2 is verified to reduce the Gibbs free energy for rate-limiting step of sulfur reduction and the dissociation energy of lithium sulfide(Li2 S) for the first time employing theoretical calculations. The Mo S2 nanosheets coated on mesoporous hollow carbon spheres(MHCS) are then reasonably designed as a sulfur host for high-capacity and long-life Li–S battery, in which MHCS can guarantee the high sulfur loading and fast electron/ion transfer. It is revealed that the shuttle effect is efficiently inhibited because of the boosted conversion of Li PSs. As a result, the coin cell based on the MHCS@Mo S2-S cathode exhibits stable cycling performance maintaining 735.7 mAh g^(-1) after 500 cycles at 1.0 C. More importantly, the pouch cell employing the MHCS@Mo S2-S cathodes achieves high specific capacity of1353.2 m Ah g^(-1) and prominent cycle stability that remaining 960.0 m Ah g^(-1) with extraordinary capacity retention of 79.8% at 0.1 C after 170 cycles. Therefore, this work paves a new avenue for developing practical high specific energy and long-life pouch-type Li–S batteries. | Qinjun Shao Pengfei Lu Lei Xu Decai Guo Jing Gao Zhong Shuai Wu jian Chen | 2020 | Journal of Energy Chemistry2020，29，12： | 7 |
| 2 | A hybrid model for numerical wave forecasting and its implementation-Ⅱ .The discrete part and implementation of the model显示文摘In the first part of the present paper we have explained why we manage to formulate another wave prediction model when so many of them, including the so-called third generation model, have already been in use. The wind-wave part of the proposed model has also been given. Now we proceed to discuss the swell part,the implementation of the model as a prediction method,mumerical experiments done with ideal wind fields and hindcasts made in the Bohai Sea,in the neighboring seas adjacent to China and in the Northwest Pacific. | Zhang Dacuo, Wu Zengmao, Jiang Decai, Wang Wei, Chen Bohai, Tai Weitao, Wen Shengchang,Xu Qichun and Guo Peifang | 1992 | Acta Oceanologica Sinica1992，11，2： | 3 |
| 3 | Isolation of a strong matrix attachment region (MAR) and identification of its function in vitro and in vivo显示文摘Inclusion of MARs in transgene cassettes enhances their expression and reduces position-effect variations in the transgenic host. Four new MARs (TM2, TM3, AM1 and AM2) were isolated from tobacco and Arabidopsis by PCR method. The nuclei isolated from suspension-cultured cells of rice were used to prepare nuclear matrix. With a characterized MAR (TM1) as a positive control, the Matrix-MAR interactions were tested by an in vitro binding assay to identify the DNA sequences as MARs and their binding strength to nuclear matrix in vitro was compared. The results showed that TM2 and TM3 had stronger binding strength than TM1. To determine the functions of the four new MARs in vivo, binary vectors pBI121 carrying a uidA GUS reporter gene were modified with direct repeat MARs inserted on both sides of the reporter gene cassette and were transferred into tobaccos via Agrobacterium-mediated transformation procedure. Quantitative GUS assays of the transgenic tobaccos showed that when flanking a GUS reporter gene | Kewei Zhang Jianmei Wang Guodong Yang Xingqi Guo Fujiang Wen Decai Cui Chengchao Zheng | 2002 | Chinese Science Bulletin2002，47，23： | 2 |

| 9 | Accurate tracking control in LOM application显示文摘The fabrication of accurate prototype from CAD model directly in short time depends on the accurate tracking control and reference trajectory planning in (Laminated Object Manufacture) LOM application. An improvement on contour accuracy is acquired by the introduction of a tracking controller and a trajectory generation policy. A model of the X-Y positioning system of LOM machine is developed as the design basis of tracking controller. The ZPETC (Zero Phase Error Tracking Controller) is used to eliminate single axis following error, thus reduce the contour error. The simulation is developed on a Maltab model based on a retrofitted LOM machine and the satisfied result is acquired. | Yadong Liu, Congxin Li, Xingui Guo, and Decai WangNational Die & Mould CAD Engineering Research Center, Shanghai Jiaotong University, Shanghai 200030, China | 2003 | Journal of University of Science and Technology Beijing2003，10，1： | 0 |
| 10 | Acquisition performance of B1I abounding with 5G signals显示文摘The widespread 5G base stations can be potential jammers for the vulnerable BeiDou B1I receivers due to its low power.Therefore,a novel analytical model is derived for the 5G signal to evaluate its impact on acquisition performance under three decision methods.The good agreement between the Monte Carlo method(MCM)through software defined receiver(SDR)and the derived expressions validates the effectiveness of the proposed algorithm.It can be found that the receivers exhibit varied responses for different 5G waveforms and decision strategies.The receiver also shows the least endurances for some kind of 5G waveforms,however,this kind of adverse effect can be cancelled by a reduced interference signal ratio(ISR),an increased integration time or a larger accumulation times. | SHANG Peng WANG Xue ZOU Decai CHU Ziyue GUO Yao | 2022 | Journal of Systems Engineering and Electronics2022，33，3： | 0 |

| 12 | Investigation of Movement and Deposition Behaviors of Solid Particles in Hydraulic Water Reservoir via the CFD‑DEM Coupling Method显示文摘Solid contamination existing as solid particles in power fluid transmission systems may lead to transmission performance reduction,system failures,and component damage.The hydraulic reservoir will deposit the contamination and store hydraulic fluid.To investigate its purification ability for solid contamination,experiments and simulations for the motion and deposition status of the typical hydraulic system particles are carried out to reveal the interaction of particles and fluid in hydraulic water reservoirs.The results show that the CFD-DEM coupling method could predict the accurate deposition position of iron particles and sand particles when ignoring the small-scale turbulence effect in the flow field.Besides,the particle motion traces and deposition patterns in the reservoir illustrate that the flow development on the bottom surface results in the particles turning,and particles tend to settle in the low flow energy position.The motion of particles is also linked to particles Stokes number,and the same-size sand particles are easily driven by the fluid.The contribution of this paper could provide a guide for predicting the particle motion and deposition pattern in the hydraulic reservoir. | Mandi Li Decai Kong Qi Guo Xiangyu Liu Jing Yao Jianjun Hu Lijuan Chen | 2022 | Chinese Journal of Mechanical Engineering2022，35，6： | 0 |
