| 1 | Runout prediction and dynamic characteristic analysis of a potential submarine landslide in Liwan 3-1 gas field显示文摘A large number of submarine landslides with different scales have been identified in the canyon area of the submarine pipeline route of Liwan 3-1 gas field. There is still much chance that submarine slope failures would happen, and the following mass movement would present great risk to the submarine pipeline. In view of this, a numerical prediction method based on Eulerian-Eulerian two-phase flow model is introduced to simulate the mass movement of potential submarine landslides. The sliding soil and ambient water are respectively simulated by Herschel-Bulkley rheology model and Newtonian fluid model. The turbulence is simulated using the k-e model. Compared with both the experiment data and Bing result, the two-phase flow model shows a good accuracy, and its result is more close to the actual situation; the dynamic coupling between soil and ambient water can be effectively simulated and the phenomena of hydroplaning and head detachment can be obtained.Finally, the soil movement of a potential submarine landslide is simulated as an example, according to the seismic profile in the canyon area. The result shows that the hydroplaning occurs during the movement process. The runout distance calculated by the two-phase flow model is 877 m, which is 27.1% larger than the Bing result.However, the peak front velocity of soil is relative small, with a maximum value of 8.32 m/s. The Bing program with a simple and rapid process can be used for a preliminary evaluation, while the two-phase flow model is more appropriate for an accurate assessment. | XIU Zongxiang LIU Lejun XIE Qiuhong LI Jiagang HU Guanghai YANG Jianghui | 2015 | Acta Oceanologica Sinica2015，34，7： | 6 |
| 2 | A Field Investigation on the Effects of Background Erosion on the Free Span Development of a Submarine Pipeline显示文摘The safety of submarine pipelines is largely influenced by free spans and corrosions. Previous studies on free spans caused by seabed scours are mainly based on the stable environment, where the background seabed scour is in equilibrium and the soil is homogeneous. To study the effects of background erosion on the free span development of subsea pipelines, a submarine pipeline located at the abandoned Yellow River subaqueous delta lobe was investigated with an integrated surveying system which included a Multibeam bathymetric system, a dual-frequency side-scan sonar, a high resolution sub-bottom profiler, and a Magnetic Flux Leakage(MFL) sensor. We found that seabed homogeneity has a great influence on the free span development of the pipeline. More specifically, for homogeneous background scours, the morphology of scour hole below the pipeline is quite similar to that without the background scour, whereas for inhomogeneous background scour, the nature of spanning is mainly dependent on the evolution of seabed morphology near the pipeline. Magnetic Flux Leakage(MFL) detection results also reveal the possible connection between long free spans and accelerated corrosion of the pipeline. | WEN Shipeng XU Jishang HU Guanghai DONG Ping SHEN Hong | 2015 | Journal of Ocean University of China2015，14，4： | 4 |

| 4 | PHASE STRUCTURE OF W-DOPED NANO-TiO2 PRODUCED BY SOL-GEL METHOD显示文摘With Ti(OBu)4 as precursor, and HAc as complexing agent, pure and W-doped TiO2 gelatins were prepared by a sol-gel method. During the process of gel formation, metal ions were dispersed in the porous TiO2 matrix.Then, powders of nano-TiO2 and W-doped nano-TiO2 were prepared by drying, grinding and heat treatment at different temperatures. The grain size and structure of the samples, pure TiO2 and W-doped, and treated at different temperatures,were studied by X-ray diffraction (XRD), Beckman Coulter Sorption Analysis and TEM.Results showed that, with increasing temperature, the TiO2 transformed from anatase to rutile and the grain size increased. This transformation and grain growth of TiO2 could be retarded by doping with W. | Yucheng Wu Xiaoye Hu Ting Xie Guanghai Li Lide Zhang | 2005 | China Particuology2005，3，4： | 3 |
| 5 | Efficacy and safety of chemotherapy combined with bevacizumab in Chinese patients with metastatic colorectal cancer:A prospective,multicenter,observational,non-interventional phaseⅣtrial显示文摘Objective:Bevacizumab has an important and evolving role in improving outcomes in patients with metastatic colorectal cancer(mCRC)worldwide and was approved in China in 2010.However,there are limited real-world data on the efficacy and safety of chemotherapy regimens combined with bevacizumab in Chinese patients with mCRC.This observational,phase IV trial study aimed to obtain more experience on the efficacy and safety of bevacizumab combined with chemotherapy in Chinese mCRC patients.Methods:Between September 2013 and November 2016,patients with histologically confirmed mCRC were enrolled in a prospective,multicenter,observational,non-interventional phase IV trial at 26 centers across China.Eligible patients received different chemotherapeutic regimens combined with bevacizumab.The efficacy and safety data in the intention-to-treat study population were analyzed.Results:A total of 611 patients were included in the efficacy analysis.The median overall survival and median progression-free survival was 18.00 and 10.05 months,respectively.The objective response rate was 21.00%and disease control rate was 89.40%.In subgroup analyses,the survival differences were observed according to metastatic status,duration of treatment and elevation in blood pressure.A total of 613 patients were evaluable for safety assessments.And 569(92.82%)patients reported at least one adverse event(AE),and 151(24.63%)experienced grade 3 or higher AEs.The incidence of bevacizumab-associated AEs of special interest was reported in 31(5.06%)patients with hypertension(n=12),abscesses and fistulae(n=7),bleeding(n=6),proteinuria(n=3),gastrointestinal perforation(n=2)and venous thrombotic events(n=1).Conclusions:This observational phase IV trial broadens our experience and knowledge of bevacizumab in the Chinese population and provides a good indication of its overall efficacy and safety.Bevacizumab in combination with chemotherapy offers clinical benefits to Chinese patients with mCRC and has an acceptable and manageable safety profile. | Fenghua Wang Guanghai Dai Yanhong Deng Yong Tang Wei Wang Zuoxing Niu Feng Bi Liangjun Zhu Zengqing Guo Jin Yan Bing Hu Min Tao Shujun Yang Suzhan Zhang Lu Wen Ruihua Xu | 2021 | Chinese Journal of Cancer Research2021，33，4： | 2 |

| 9 | Variations of calcareous nannofossils of cobalt-rich crusts and geological records at the Eocene-OIigocene transition in western Pacific seamounts显示文摘Two records of the crust laminae from the Marcus-Wake Seamounts and the Magellan Seamount were biostratigraphically studied. Based on biological imprints of the calcareous nannofossils, the geological ages of the two records were determined, with CM1D03 from the Marcus-Wake Seamounts being of late Paleocene to Pleistocene and CM3D06 from the Magellan Seamount of Late Cretaceous(more than 70.0 Ma). There are the obvious temporal-spatial differences in the initial formation period and enrichment characteristics of the cobalt-rich crusts of the two seamount chains and differences in the combination and distribution of microfossils in the inner crust layers between the seamounts. These differences are due to the adaptabilities of oceanic species in different environments. Ecological research was carried out in terms of population size of the calcareous nannofossils preserved in the crustal layers to discern the relation of the geological events at the Eocene-Oligocene(E/O) transition. The results show the transitions and recombination of species in the biotic community during the E/O transition obviously corresponded to 25 mm depth in the CM1D03 crust and 58 mm depth in the CM3D06 crust. The changes in biological species and the formation of particular ecological structures indicate the adaptive response of the paleo-biological community in the western Pacific Ocean to the global cold-climate events and the close correlation between the formation of the crust and the global climate change. | ZHANG HaiSheng HU Ji ZHAO Jun HAN ZhengBing YU PeiSong WU GuangHai LEI Ji Jiang LU Bing Irina A PULYAEVA | 2015 | Science China Earth Sciences2015，58，5： | 1 |

| 12 | Size Distribution of Submarine Landslides Along the Middle Continental Slope of the East China Sea显示文摘This paper investigates the size distribution of submarine landslides on the middle continental slope of the East China Sea (ECS) using the size of the landslide source regions. Geomorphometric mapping is used to identify 102 mass movements from multibeam bathymetric data and to extract morphological information about the head scarps and side walls. These mass movements have areas ranging between 0.06 km2 and 15.51 km2 and volumes between 0.002 km3 and 2 km3. The area vs volume relationship of these failure scarps is approximately linear, suggesting a fairly uniform failure thickness in each event with scarce deep excavating landslides. The cumulative area distribution of the slope failures can be described by an inverse power law. The submarine landslides on the mid-ECS continental slope could be considered as a large-scale self-organizing system because they have the characteristics of a dissipative system in a critical state. | HU Guanghai YAN Tong LIU Zhenxia Maarten Vanneste DONG Lifeng | 2009 | Journal of Ocean University of China2009，8，4： | 0 |
| 13 | Self-supported NiFe-LDH nanosheets on NiMo-based nanorods as high-performance bifunctional electrocatalysts for overall water splitting at industrial-level current densities显示文摘Efficient,durable and economic electrocatalysts are crucial for commercializing water electrolysis technology.Herein,we report an advanced bifunctional electrocatalyst for alkaline water splitting by growing NiFe-layered double hydroxide(NiFe-LDH)nanosheet arrays on the conductive NiMo-based nanorods deposited on Ni foam to form a three-dimensional(3D)architecture,which exhibits exceptional performances for both hydrogen evolution reaction(HER)and oxygen evolution reaction(OER).In overall water splitting,only the low operation voltages of 1.45/1.61 V are required to reach the current density of 10/500 mA·cm^(-2),and the continuous water splitting at an industrial-level current density of 500 mA·cm^(-2) shows a negligible degradation(1.8%)of the cell voltage over 1000 h.The outstanding performance is ascribed to the synergism of the HER-active NiMo-based nanorods and the OER-active NiFe-LDH nanosheet arrays of the hybridized 3D architecture.Specifically,the dense NiFe-LDH nanosheet arrays enhance the local pH on cathode by retarding OH-diffusion and enlarge the electrochemically active surface area on anode,while the conductive NiMo-based nanorods on Ni foam much decrease the charge-transfer resistances of both electrodes.This study provides an efficient strategy to explore advanced bifunctional electrocatalysts for overall water splitting by rationally hybridizing HER-and OER-active components. | Yan Zhang Biao Feng MingLei Yan Zhen Shen Yiqun Chen Jingyi Tian Fengfei Xu Guanghai Chen Xizhang Wang Lijun Yang Qiang Wu Zheng Hu | 2024 | Nano Research2024，17，5： | 0 |
| 14 | Alloyed Pt-Sn nanoparticles on hierarchical nitrogen-doped carbon nanocages for advanced glycerol electrooxidation显示文摘Glycerol is an alternative sustainable fuel for fuel cells,and efficient electrocatalyst is crucial for glycerol oxidation reaction(GOR).The promising Pt catalysts are subject to the inadequate capability of C-C bond cleavage and the susceptibility to poisoning.Herein,Pt-Sn alloyed nanoparticles are immobilized on hierarchical nitrogen-doped carbon nanocages(hNCNCs)by convenient ethylene glycol reduction and subsequent thermal reduction.The optimal Pt_(3)Sn/hNCNC catalyst exhibits excellent GOR performance with a high mass activity(5.9 A·mg_(Pt)^(-1)),which is 2.7 and 5.4 times higher than that of Pt/hNCNC and commercial Pt/C,respectively.Such an enhancement can be mainly ascribed to the increased anti-poisoning and C-C bond cleavage capability due to the Pt_(3)Sn alloying effect and Sn-enriched surface,the high dispersion of Pt_(3)Sn active species due to N-participation,as well as the high accessibility of Pt_(3)Sn active species due to the three-dimensional(3D)hierarchical architecture of hNCNC.This study provides an effective GOR electrocatalyst and convenient approach for catalyst preparation. | Jietao Jiang Liqi Zhou Fengfei Xu Guanghai Chen Xiaoyu Liu Zhen Shen Lijun Yang Qiang Wu Xizhang Wang Zheng Hu | 2024 | Nano Research2024，17，5： | 0 |
