| 1 | Tectonic Evolution of the Meso-Tethys in the Western Segment of Bangonghu-Nujiang Suture Zone: Insights from Geochemistry and Geochronology of the Lagkor Tso Ophiolite显示文摘The subduction of the Bangonghu-Nujiang Meso-Tethys and the collision between the Lhasa and Qiangtang blocks were important events in the growth of the Tibetan crust. However,the timing of collision initiation and closure timing,as well as nature and structure of the Bangonghu ocean basin,are still poorly constrained. The Lagkor Tso ophiolite,located in the south of Gerze County,Tibet,is one of the most completed ophiolites preserved in the southern side of the BangonghuNujiang suture zone. This study discussed the tectonic evolution of the Bangonghu-Nujiang suture zone as revealed by the Lagkor Tso ophiolite investigated by field investigations,petrology,geochemistry,geochronology and tectonic analysis methods. We present new LA-ICP-MS zircon U-Pb and 39Ar/40 Ar ages for the Lagkor Tso ophiolite,in addition to geochemical and platinum-group element(PGE) data presented for the Lagkor Tso ophiolite in Tibet. It is suggested that the ancient Lagkor Tso oceanic basin split in Middle Jurassic(161.2 ± 2.7 Ma – 165.4 ± 3.5 Ma),and experienced a second tectonic emplacement during the Early Cretaceous(137.90 ± 6.39 Ma). The Lagkor Tso ophiolite likely developed in an independent suture zone. The Bangonghu-Nujiang ocean subducted southwards,and the dehydration of the subducting oceanic crust materials caused partial melting of the continental mantle wedge,which formed the second-order expanding center of the obduction dish. This led to inter-arc expansion,followed by the formation of inter-arc and back-arc basins with island arc features,which are represented by ophiolites around the Shiquanhe-Lagkor Tso-Yongzhu region. The tectonic environment presently can be considered to be similar to that of the current Western Pacific,in which a large number of island arc-ocean basin systems are developed. | YUAN Yajuan YIN Zhengxin LIU Weiliang HUANG Qiangtai LI Jianfeng LIU Hongfei WAN Zhifeng CAI Zhourong XIA Bin | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 17 |
| 2 | Construction of ZnIn_(2)S_(4)-CdIn_(2)S_(4) Microspheres for Efficient Photo-catalytic Reduction of CO_(2) with Visible Light显示文摘ZnIn_(2)S_(4) has emerged in water splitting and degradation of dyes due to its good stability and light absorption properties.However,there are still few reports of CO_(2) photoreduction.Herein,we successfully synthesized ZnIn_(2)S_(4) and obtained a series of ZnIn_(2)S_(4)-CdIn_(2)S_(4) heterostructured microspheres through the ion exchange method,and first used them in photocatalytic CO_(2) reduction in noble-metal-free systems.The activity results showed that these ZnIn_(2)S_(4)-CdIn_(2)S_(4) photocatalysts exhibit excellent catalytic activity under visible light,and the best CO yield is as high as 33.57μmol・h^(-1) with a selectivity of 91%.Furthermore,the stability and reusability of ZnIn_(2)S_(4)-CdIn_(2)S_(4) was firmly confirmed by diverse characterizations,including X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),energy-dispersive X-ray spectroscopy(EDX)and N2 adsorption measurements. | Shitong Han Bifang Li Lijuan Huang Hailing Xi Zhengxin Ding Jinlin Long | 2022 | Chinese Journal of Structural Chemistry2022，41，1： | 2 |

| 8 | Zircon U-Pb Geochronology and Hf Isotopic Constraints on Petrogenesis of Plagiogranite from the Cuomuqu Ophiolite,Bangong Lake Area,North Tibet显示文摘Field observation,geochemical signatures and zircon Hf isotope data indicate that Cuomuqu ophiolite in the Bangonghu area was formed in a back-arc basin(BAB) above a suprasubduction zone(SSZ). Zircon U-Pb dating of the diabase from the Cuomuqu massif yielded an age of 164.3±1.9 Ma,thus indicating that the ophiolite complex was formed in the Middle Jurassic during back-arc extension of the mature Bangonghu-Nujiang Ocean. The zircon εHf(t) and TDMC values of the plagiogranite are similar to the εHf(t) and TDM of the diabase,respectively. The mode of occurrence of plagiogranites and their bulk-rock and Hf isotope characteristics indicate that they were derived from the mantle,associated with the surrounding gabbro and diabase,and were formed by partial melting of altered and hydrated mafic rocks under shear conditions during lateral drifting of the oceanic crust. The zircon U-Pb age of the plagiogranite is 156.4±1.4 Ma,and it is 7.9 Ma younger than the hosting diabase. In this study,zircon chronological and Hf isotopic data were tentatively analyzed to determine the genesis of plagiogranites in the Cuomuqu ophiolite complex. | YIN Zhengxin YUAN Yajuan Lü Baofeng CAI Zhourong ZHENG Hao HUANG Qiangtai XIA Bin ZHONG Yun XIA Zhongyu SHI Xiaolong GUAN Yao | 2015 | Acta Geologica Sinica(English Edition)2015，89，2： | 1 |
| 9 | Improving dynamics of integer-order small-world network models under fractional-order PD control显示文摘The optimal control of dynamics is a popular topic for small-world networks. In this paper, we address the problem of improving the behavior of Hopf bifurcations in an integer-order model of small-world networks. In this study, the time delay is used as the bifurcation parameter. We add a fractional-order proportional-derivative(PD) scheme to an integer-order Newman-Watts(N-W) small-world model to better control the Hopf bifurcation of the model. The most important contribution of this paper involves obtaining the stability of the system and the variation of the conditions of the Hopf bifurcation after a fractional PD controller is added to the integer-order small-world model. The results demonstrate that the designed PD controller can be used to restrain or promote the occurrence of Hopf bifurcations by setting appropriate parameters. We also describe several simulations to verify our research results. | Huaifei WANG Min XIAO Binbin TAO Fengyu XU Zhengxin WANG Chengdai HUANG Jianlong QIU | 2020 | Science China(Information Sciences)2020，63，1： | 1 |
| 10 | 基于模型的航空发动机气路故障容错控制方法显示文摘A fault tolerant control method is proposed in this paper for a turbofan engine gas path degradation through the full flight envelope. A Quantum-behaved Particle Swarm Optimization(QPSO) algorithm is applied to obtain engine inputs adjustments, which contribute to construct off-line performance accommodation interpolation schedules. With a double closed-loop control system structure, command control is corrected based on real-time fault diagnostic results. Simulations indicate that fault tolerant control could reduce thrust and stall margin loss effectively in gas path faults. | WANG Cancan LI Zhengxin HUANG Jinquan | 2021 | Aerospace China2021，22，4： | 0 |

| 12 | S-scheme CoTiO_(3)/Cd_(9.51)Zn_(0.49)S_(10)heterostructures for visible-light driven photocatalytic CO_(2) reduction显示文摘CdZnS solid solutions with strong light absorption are promising materials for solar-driven COreduction;however,their relatively weak redox ability and intrinsic photo-corrosion limit their further development as a photocatalyst.The addition of a second photocatalyst with a suitable band structure to construct a S-scheme photocatalytic system can solve both problems simultaneously.Here,we report a S-scheme photocatalyst based on the heterostructure of CoTiO_(3)/CdZnS(abbreviated as CoTiO_(3)/Cd_(9.51)Zn_(0.49)S_(10))that enables the efficient photocatalytic reduction of CO.Detailed physicochemical characterization resolves the S-scheme charge transfer mechanism in this composite photocatalyst.With the well-designed structure of particles and desirable band offsets,this hybrid system offers visible light absorption in a broad spectral region,large surface area,strong redox ability,and fast carrier separation and transportation.Under visible-light illumination,the CoTiO_(3)/Cd Zn S hybrid system displays a CO formation rate of about 11 mmol hgcombined with a long-term operational stability.Besides,a high apparent quantum efficiency(AQE)of 7.27%is realized for the CO_(2)-to-CO reduction reaction by the optimized Co TiO/Cd Zn S hybrid under 420 nm monochromatic light irradiation. | Bo Su Haowei Huang Zhengxin Ding Maarten B.J.Roeffaers Sibo Wang Jinlin Long | 2022 | Journal of Materials Science & Technology2022，，29： | 0 |
| 13 | Selectively converting CO_(2) to HCOOH on Cu-alloys integrated in hematite-driven artificial photosynthetic cells显示文摘The integration of electrochemical CO_(2)reduction(CO_(2)RR) and photoelectrochemical water oxidation offers a sustainable access to valuable chemicals and fuels. Here, we develop a rapidly annealed hematite photoanode with a photocurrent density of 2.83 mA cm^(-2)at 1.7 VRHEto drive the full-reaction. We also present Cu-alloys electrocatalysis extended from CuInSnS4, which are superior in both activity and selectivity for CO_(2)RR. Specifically, the screened CuInSn achieves a CO_(2)to HCOOH Faradaic efficiency of 93% at a cell voltage of-2.0 V by assembling into artificial photosynthesis cell. The stability test of IT exhibits less than 3% degradation over 24 h. Furthermore, in-situ Raman spectroscopy reveals that both CO_(3)^(-2)and CO_(2)are involved in CO_(2)RR as reactants. The preferential affinity of C for H in the ^(*)HCO_(2)intermediate enables an improved HCOOH-selectivity, highlighting the role of multifunctional Cu in reducing the cell voltage and enhancing the photocurrent density. | Jiwu Zhao Liang Huang Lan Xue Zhenjie Niu Zizhong Zhang Zhengxin Ding Rusheng Yuan Xu Lu Jinlin Long | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
| 14 | Tectonic unit divisions based on block tectonics theory in the South China Sea and its adjacent areas显示文摘Identifying distinct tectonic units is key to understanding the geotectonic framework and distribution law of oil and gas resources.The South China Sea and its adjacent areas have undergone complex tectonic evolution processes,and the division of tectonic units is controversial.Guided by block tectonics theory,this study divide the South China Sea and its adjacent areas into several distinguished tectonic units relying on known boundary markers such as sutures(ophiolite belts),subduction-collision zones,orogenic belts,and deep faults.This work suggests that the study area is occupied by nine stable blocks(West Burma Block,Sibumasu Block,LanpingSimao Block,Indochina Block,Yangtze Block,Cathaysian Block,Qiongnan Block,Nansha Block,and Northwest Sulu Block),two suture zones(Majiang suture zone and Southeast Yangtze suture zone),two accretionary zones(Sarawak-Sulu accretionary zone and East Sulawesi accretionary zone),one subduction-collision zone(RakhineJava-Timor subduction-collision zone),one ramp zone(Philippine islands ramp zone),and six small oceanic marginal sea basins(South China Sea Basin,Sulu Sea Basin,Sulawesi Sea Basin,Banda Sea Basin,Makassar Basin,and Andaman Sea Basin).This division reflects the tectonic activities,crustal structural properties,and evolutionary records of each evaluated tectonic unit.It is of great theoretical and practical importance to understand the tectonic framework to support the exploration of oil and gas resources in the South China Sea and its adjacent areas. | Zhengxin Yin Zhourong Cai Cheng Zhang Xiaofeng Huang Qianru Huang Liang Chen | 2021 | Acta Oceanologica Sinica2021，40，9： | 0 |
| 15 | Tirapazamine encapsulated hyaluronic acid nanomicelles realized targeted and efficient photo-bioreductive cascading cancer therapy显示文摘Currently,architecting a ratio nal and efficient nanoplatform combing with multi-therapeutic modalities is highly obligatory for advanced cancer treatment.In order to remedy the self-limiting hypoxic dilemma of photodynamic therapy(PDT),herein,a facile photosensitizer(i.e.,chlorin e6,Ce6) and bioreductive prodrug(i.e.,tirapazamine,TPZ)-coloaded hyaluronic acid(HA) nanomicelles(denoted as TPZ@HA-Ce6)was developed for the cascading mode of photo-bioreductive cancer therapy.Taking the typical advantage of Ce6 coupled HA conjugate,TPZ was easily and successfully accommodated into the hydrophobic core of HA-Ce6 nanomicelles,yielding TPZ@HA-Ce6.It showed good dispersibility and stability with the hydrodynamic size of ca.170 nm.It targeted the CD44 overexpressed cancer cells by receptor-mediated endocytosis way and killed them effectively with singlet oxygen and the subsequent TPZ radicals resulting from the oxygen depletion of PDT.The later was further verified by the hypoxia probe in vivo.Using murine mammary carcinoma 4 T1 model,TPZ@HA-Ce6 nanomicelles exhibited cascading and synergistic anticancer effect of PDT and TPZ bioreductive therapy compared with each monotherapy.This work suggests the promising prospect of the hybrid hyaluronic nanomicelles for highly efficient cancer combination treatment. | Chunhui Wu Qiuyue Liu Yikun Wang Zhengxin Xie Honglin Huang Ningxi Li Xiaodan Wei Geng Yang Tingting Li Hong Yang Shun Li Xiang Qin Yiyao Liu | 2021 | Chinese Chemical Letters2021，32，8： | 0 |
