| 1 | Thresholds of geographic environmental elements in sediment yield of drainage basins显示文摘Threshold of environmental elements in drainage basin sediment yield refers to, under effect of climate, underlying surface and human activity, a turning point of abrupt changes in drainage sediment yield related to environmental element characteristics. Previous studies on threshold of sediment yield of relevant drainage basins were mainly concentrated on impact of natural zones with a few researches on impact of other environmental elements. Particularly studies on compound environmental element threshold in drainage basin sediment yield remain blank today. Studies indicate that sediment yield in drainage basins is affected by compound interactions and complex actions. Based on single element analysis, the present paper gives quantitatively compound threshold of environmental elements affecting sediment yield of the drainage basin between Hekouzhen and Tongguan in the middle Yellow River by the method of multi-variant, polynomial formula regression analysis. | CHEN Hao, ZHOU Jinxing, CAI Qiangguo, LU Zhongchen & LI Zhongyan Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Institute of Forestry Science, Chinese Academy of Forestry Science, Beijing 100091, China Research Center for Eco-Environment Sciences, Chinese Academy of Sciences, Beijing 100085, China Computing Institute of Science and Engineering, North China Electric Power University, Beijing 102206, China | 2005 | Science China Earth Sciences2005,48,2: | 6 |
| 2 | The effects of vegetation restoration strategies and seasons on soil enzyme activities in the Karst landscapes of Yunnan, southwest China显示文摘Soil enzymes play a vital role in biogeochemical cycling and ecosystem functions.In this study,we examined the response of six soil enzymes to changes in physicochemical properties resulting from changes in season and vegetation and geological conditions.Catalase,urease,acid phosphatase,invertase,amylase,and cellulase not only promote carbon,nitrogen,and phosphorus cycling,but also participate in the decomposition of harmful substances.Thirty-six soil samples were collected from karst and non-karst areas in two different seasons and from three different types of vegetation in Yunnan province,southwest China.Both vegetation types and season had significant effects on soil physicochemical properties and enzyme activities.In the same plot,soil water content,electrical conductivity,organic carbon,total nitrogen,and total phosphorus increased in the rainy season,indicating enhanced microbial metabolic activity.With the exception of urease activity,the remaining five enzymes showed higher activity in the rainy season.Changes in activities between the two seasons were significant in all samples.In the same season,activity levels of soil enzymes were higher in karst areas than in non-karst areas,and higher in natural forest than in artificial forests.The transformative abilities of soil elements are higher in karst areas than in non-karst areas,and higher in natural forests than in artificial forests.Correlation analysis showed that the activities of the six enzymes correlated significantly;however,soil physical and chemical indices,such as organic matter,pH,and moisture,which are essential for enzyme activity,differed by season.Redundancy analysis also revealed that the main factors influencing enzyme activity differed between the two seasons.The results from this study provide a theoretical basis for further research on the restoration of natural ecological systems in karst landscapes. | Zhouzhou Fan Shuyu Lu Shuang Liu Zhaorong Li Jiaxin Hong Jinxing Zhou Xiawei Peng | 2020 | Journal of Forestry Research2020,31,5: | 5 |
| 3 | Helium isotopic compositions in fluid inclusions of the Gangxi fault belt in the Huanghua Depression, Bohai Bay Basin显示文摘The authors obtained 30 core samples from 15 wells in Gangxi fault belt, Huanghua Depression. Using a VG5400 mass spectrometer, the helium isotopic compositions in fluid inclusion of these samples were analysed. Interpreta- tion of results suggests a significant amount of man- tle-derived helium in the inclusions, which were likely trapped during Neocene. Mantle-derived helium have mostly accumulated in the intersections of the NWW trending Xuz- huangzi and NE trending Gangxi faults, and decreased away from the intersections. This pattern implied a close relation- ship to the local tectonic setting. Gangxi fault belt experi- enced intensive neo-tectonic activities in the Cenozoic. Widespread faulted-depressions and strong volcanic erup- tions manifested its tectonic status of extensional stress field. Mantle uplift caused the movement of magma that carried mantle-derived gas, and the deep-rooted tension faults pro- vided the passages for the gases to shallow crust levels. High-content abiogenic CO2 pools occurred in the study area, hence, using the helium isotopic compositions is of great sig- nificance to the exploration of abiogenic natural gases. | DING Weiwei DAI Jinxing YANG Chiyin TAO Shizhen HOU LU | 2005 | Chinese Science Bulletin2005,50,22: | 4 |

| 6 | Recent progress in Chinese fusion research based on superconducting tokamak configuration显示文摘Fusion energy is a promising source of clean energy,which could solve energy shortages and environmental pollution.Research into controlled fusion energy has been ongoing for over half a century.China has created a clear roadmap for magnetic confinement fusion development,where superconducting tokamaks will be used in commercial fusion reactors.The Experimental Advanced Superconducting Tokamak(EAST)is the world’s first fully superconducting tokamak with upper and lower divertors,which aims at longpulse,steady-state,H-mode operation,and 101-s H-mode discharge had been achieved.In 2007,China joined the International Thermonuclear Experimental Reactor(ITER)and became one of its seven members.Thirteen procurement packages are undertaken by China,covering superconducting magnets,power supplies,plasma-facing components(PFCs),diagnostics,etc.To bridge the gap between the ITER and fusion demonstration power plants(DEMOs),China is planning to build the Chinese Fusion Engineering Testing Reactor(CFETR)to demonstrate related technologies and physics models.The engineering design of the CFETR was completed in 2020,and Comprehensive Research Facilities for Fusion Technology(CRAFT)are being constructed to explore the key technologies used in the CFETR. | Jinxing Zheng Jinggang Qin Kun Lu Min Xu Xuru Duan Guosheng Xu Jiansheng Hu Xianzu Gong Qing Zang Zhihong Liu Liang Wang Rui Ding Jiming Chen Pengyuan Li Lei Xue Lijun Cai Yuntao Song | 2022 | The Innovation2022,3,4: | 3 |
| 7 | Transparent,stretchable,temperature-stable and self-healing ionogel-based triboelectric nanogenerator for biomechanical energy collection显示文摘A flexible and stable power supply is essential to the rapid development of wearable electronic devices.In this work,a transparent,flexible,temperature-stable and ionogel electrode-based self-healing triboelectric nanogenerator(IS-TENG)was developed.The ionogel with excellent stretchability(1,012%),high ionic conductivity(0.3 S·m^(−1))and high-temperature stability(temperature range of−77 to 250℃)was used as the electrode of the IS-TENG.The IS-TENG exhibited excellent transparency(92.1%)and stability.The output performance did not decrease when placed in a 60℃oven for 48 h.In addition,the IS-TENG behaved like a stable output in the range of−20 to 60℃.More importantly,the IS-TENG could also achieve self-healing of electrical performance at temperatures between−20 and 60℃and its output can be restored to its original state after healing.When the single-electrode IS-TENG with an area of 3 cm×3 cm was conducted under the working frequency of 1.5 Hz,the output values for open-circuit voltage,short-circuit current,short-circuit transferred charge,and maximum peak power density were 189 V,6.2μA,57 nC,and 2.17 W·m^(−2),respectively.The IS-TENG enables to harvest biomechanical energy,and drive electronic devices.Furthermore,the application of IS-TENGs as self-driven sensors for detecting human behavior was also demonstrated,showing good application prospects in the field of wearable power technology and self-driven sensing. | Weiqiang Liao Xiukun Liu Yuqi Li Xu Xu Jinxing Jiang Shaorong Lu Dequan Bao Zhen Wen Xuhui Sun | 2022 | Nano Research2022,15,3: | 2 |
| 8 | Study on Cutting Force,Cutting Temperature and Machining Residual Stress in Precision Turning of Pure Iron with Different Grain Sizes显示文摘Pure iron is one of the difficult-to-machine materials due to its large chip deformation,adhesion,work-hardening,and built-up edges formation during machining.This leads to a large workpiece deformation and challenge to meet the required technical indicators.Therefore,under varying the grain size of pure iron,the influence of cutting speed,feed,and depth of cut on the cutting force,heat generation,and machining residual stresses were explored in the turning process to improve the machinability without compromising the mechanical properties of the material.The experimental findings have depicted that the influence of grain size on cutting force in the precision turning process is not apparent.However,the cutting temperature and residual stress of machining fine-grain iron were much smaller than the coarse grain at all levels of cutting parameters. | Yinfei Yang Lu Jin Jinpeng Zhu Jinxing Kong Liang Li | 2020 | Chinese Journal of Mechanical Engineering2020,33,4: | 2 |

| 17 | Disease X Testing:The results of an international external quality assessment exercise显示文摘The United Nations Secretary-General Mechanism(UNSGM)for investigation of the alleged use of chemical and biological weapons is the only established international mechanism of this type under the UN.The UNGSM may launch an international investigation,relying on a roster of expert consultants,qualified experts,and analytical laboratories nominated by the member states.Under the framework of the UNSGM,we organized an external quality assurance exercise for nominated laboratories,named the Disease X Test,to improve the ability to discover and identify new pathogens that may cause possible epidemics and to determine their animal origin.The“what-if”scenario was to identify the etiological agent responsible for an outbreak that has tested negative for many known pathogens,including viruses and bacteria.Three microbes were added to the samples,Dabie bandavirus,Mammarenavirus,and Gemella spp.,of which the last two have not been taxonomically named or published.The animal samples were from Rattus norvegicus,Marmota himalayana,New Zealand white rabbit,and the tick Haemaphysalis longicornis.Of the 11 international laboratories that participated in this activity,six accurately identified pathogen X as a new Mammarenavirus,and five correctly identified the animal origin as R.norvegicus.These results showed that many laboratories under the UNSGM have the capacity and ability to identify a new virus during a possible international investigation of a suspected biological event.The technical details are discussed in this report. | Tian Qin Han Zheng Xuelian Luo Wen Zhang Jing Yang Yamin Sun Na Han Yuanhai You Liang Lu Xin Lu Di Xiao Shenshen Jiang Xuexin Hou Jinxing Lu Biao Kan Jianzhong Zhang Jianguo | 2022 | Journal of Biosafety and Biosecurity2022,4,2: | 0 |
| 18 | Site-Selective Polyolefin Hydrogenolysis on Atomic Ru for Methanation Suppression and Liquid Fuel Production显示文摘Catalytic hydrogenolysis of end-of-life polyolefins can produce value-added liquid fuels and therefore holds great promises in plastic waste reuse and environmental remediation.The major challenge limiting the recycling economic benefit is the severe methanation(usually>20%)induced by terminal C–C cleavage and fragmentation in polyolefin chains.Here,we overcome this challenge by demonstrating that Ru single-atom catalyst can effectively suppress methanation by inhibiting terminal C–C cleavage and preventing chain fragmentation that typically occurs on multi-Ru sites.The Ru single-atom catalyst supported on CeO_(2)shows an ultralow CH_(4)yield of 2.2%and a liquid fuel yield of over 94.5%with a production rate of 314.93 gfuels gRu^(−1)h^(−1)at 250℃for 6 h.Such remarkable catalytic activity and selectivity of Ru single-atom catalyst in polyolefin hydrogenolysis offer immense opportunities for plastic upcycling. | Mingyu Chu Xianpeng Wang Xuchun Wang Xiangxi Lou Congyang Zhang Muhan Cao Lu Wang Youyong Li Sibao Liu Tsun-Kong Sham Qiao Zhang Jinxing Chen | 2023 | Research2023,,3: | 0 |
