| 2 | Dinitrogen cleavage and hydrogenation to ammonia with a uranium complex显示文摘The Haber-Bosch process produces ammonia(NH_(3))from dinitrogen(N_(2))and dihydrogen(H_(2)),but re quires high temperature and pressure.Before iron-based catalysts were exploited in the current industrial Haber-Bosch process,uranium-based materials served as effective catalysts for production of NH_(3)from N_(2).Although some molecular uranium complexes are known to be capable of combining with N_(2),further hydrogenation with H_(2)forming NH_(3)has not been reported to date.Here,we describe the first example of N_(2)cleavage and hydrogenation with H_(2)to NH_(3)with a molecular uranium complex.The N_(2)cleavage product contains three uranium centers that are bridged by three imido μ_(2)-NH ligands and one nitrido μ_(3)-N ligand.Labeling experiments with^(15)N demonstrate that the nitrido ligand in the product originates from N_(2).Reaction of the N_(2)-cleaved complex with H_(2)or H^(+)forms NH_(3)under mild conditions.A synthetic cycle has been established by the reaction of the N_(2)-cleaved complex with trimethylsilyl chloride.The isolation of this trinuclear imido-nitrido product implies that a multi-metallic uranium assembly plays an important role in the activation of N_(2). | Xiaoqing Xin Iskander Douair Yue Zhao Shuao Wang Laurent Maron Congqing Zhu | 2023 | National Science Review2023，10，2： | 0 |
| 3 | Inverse Model Control for a Quad-rotor Aircraft Using TS-fuzzy Support Vector Regression显示文摘An inverse model control based on TS-fuzzy support vector regression( TS-fuzzy SVR) for a quadrotor aircraft is developed. The TS-kernel is the product of linear combination of input and a cluster of output corresponding to a cluster of TS-type fuzzy rules. The output of TS-fuzzy SVR is a linear weighted sum of the TSkernels. The dynamical model of the quad-rotor aircraft is derived. A new control scheme combined with TSfuzzy SVR inverse model control and PID control is presented so that the TS-fuzzy SVR inverse model control enhances capabilities of disturbance rejection and the robustness while the PID control enhances fast responsiveness and reliability of the system. Simulation results show the capabilities of the developed control for the attitude system of quad-rotor aircraft. | Zhiyu Li Hanxin Chen Congqing Wang Kaijia Xue | 2017 | Journal of Harbin Institute of Technology(New Series)2017，24，6： | 0 |
| 4 | Modelling and Backstepping Motion Control of the Aircraft Skin Inspection Robot显示文摘Aircraft skin health concerns whether the aircraft can fly safely.In this paper,an improved mechanical structure of the aircraft skin inspection robot was introduced.Considering that the aircraft skin surface is a curved environment,we assume that the curved environment is equivalent to an inclined plane with a change in inclination.Based on this assumption,the Cartesian dynamics model of the robot is established using the Lagrange method.In order to control the robot’s movement position accurately,a position backstepping control scheme for the aircraft skin inspection robot was presented.According to the dynamic model and taking into account the problems faced by the robot during its movement,a position constrained controller of the aircraft skin inspection robot is designed using the barrier Lyapunov function.Aiming at the disturbances in the robot,we adopt a fuzzy system to approximate the unknown dynamics related with system states.Finally,the simulation results of the designed position constrained controller were compared with the sliding mode controller,and prove the validity of the position constrained controller. | Junjun Jiang Congqing Wang | 2019 | Computer Modeling in Engineering & Sciences2019，，7： | 0 |
| 5 | Uranium(Ⅲ)–Phosphorus(Ⅲ) Synergistic Activation of White Phosphorus and Arsenic显示文摘The study of small-molecule activation by f-block elements still lags far behind that of transition metals.Although a few uranium complexes have been reported to activate dinitrogen,reports on the activation of heavier congeners,such as white phosphorus(P_(4)),by uranium species are extremely rare,and no example of uranium-mediated activation of elemental arsenic has appeared. | Wei Fang Iskander Douair Adrian Hauser Kai Li Yue Zhao Peter WRoesky Shuao Wang Laurent Maron Congqing Zhu | 2022 | CCS Chemistry2022，4，8： | 0 |
| 6 | Complex Featuring Two Double Dative Bonds Between Carbon(0)and Uranium显示文摘The uranyl with two U=O double bonds is a wellknown and predominant form of uranium in the environment,but the carbon-based analog with two U=C double bonds has rarely been synthesized.Here,we describe the formation of an unprecedented uranium complex[(PyPh_(2)P)_(2)C]_(2)UCl_(2)]^(2+)·2(BPh_(4)^(−))from the reaction of UCl4 with carbodiphosphorane in the presence of NaBPh4.The nature of the U-C bonds was revealed by density functional theory calculations,which show that the 5f and 6d orbital electrons of uranium are remarkably involved in the U=C double bonds.The inspection of the bonding characteristics with an energy decomposition analysis suggests that the uranium-ligand bond may be alternatively described with double dative bonds[C⇉U⇇C]or strong electron-sharing π bonds and weak σ bonds. | Wei Fang Sudip Pan Wei Su Shuao Wang Lili Zhao Gernot Frenking Congqing Zhu | 2022 | CCS Chemistry2022，4，6： | 0 |
| 7 | Carbon-halogen bond activation by a structurally constrained phosphorus(Ⅲ)platform显示文摘Theσ-bond activation by main group element has received enormous attention from theoretical and experimental chemists.Here,the reaction of C-X(X=Cl,Br,I)bonds in benzyl and allyl halides with a pincer-type phosphorus(Ⅲ)species was reported.A series of structurally robust phosphorus(Ⅴ)compounds were formed via the formal oxidative addition reactions of C-X bonds to the phosphorus(Ⅲ)center.Density functional theory calculations show that the nucleophilic addition process is more favorable than the direct oxidative addition mechanism.Isomerization of bent structures of phosphorus(Ⅲ)compound to poorly nucleophilic compounds to undergo further C-X bond activation can be rationalized by frontier molecule orbital analysis.This study not only provides a deep understanding of the reactivity of phosphorus(Ⅲ)species but also demonstrates a potential of main group elements for the small-molecule activation. | Penglong Wang Qin Zhu Yi Wang Guixiang Zeng Jun Zhu Congqing Zhu | 2021 | Chinese Chemical Letters2021，32，4： | 0 |
