| 1 | Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios. | Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang | 2022 | Science China(Life Sciences)2022,65,5: | 32 |

| 3 | High phosphate removal using La(OH)3 loaded chitosan based composites and mechanistic study显示文摘Our present study was to prepare a biomass-supported adsorbents with high adsorptive capacity and high selectivity to prevent the accelerated eutrophication in water body.To this end,different metal hydroxide(La,Zr and Fe)first was successfully loaded on chitosan microspheres.Then the quaternary ammonium group with different content was introduced into the adsorbent by polymerization.By comparison of adsorption properties,chitosanLa(OH)3-quaternary ammonium-20%(CS-La-N-20%)has strong adsorption to phosphate(160 mg/g)by immobilizing nano-sized La(OH)3 within a quaternary-aminated chitosan and it maintain high adsorption in the presence of salt ions.The pH results indicated that the CS-La-N-20%would effectively sequestrate phosphate over a wide pH range between 3 and 7 without significant La3+leaching.What’s more,adsorption capacity on the introduce of positively charged quanternary-aminated groups was significantly higher than that of the unmodified adsorbents at alkaline conditions.The column adsorption capacity reached 1300 bed volumes(BV)when phosphate concentration decreased until 0.5 mg/L at 6 BV/hr.The column adsorption/desorption reveals that no significant capacity loss is observed,indicating excellent stability and repeated use property.Characterizations revealed that phosphate adsorption on CS-La-N-20%through ligand exchange(impregnated nano-La(OH)3)and electrostatic attraction(positively charged quanternary-aminated groups).All the results suggested that CS-La-N-20%can serve as a promising adsorbent for preferable phosphate removal in realistic application. | Shaopeng Zhang Yi Zhang Jie Ding Zepeng Zhang Chao Gao Muslim Halimi Hary Demey Zhen Yang Weiben Yang | 2021 | Journal of Environmental Sciences2021,33,8: | 3 |
| 4 | Targeted Ptpn11 deletion in mice reveals the essential role of SHP2 in osteoblast differentiation and skeletal homeostasis显示文摘The maturation and function of osteoblasts(OBs)rely heavily on the reversible phosphorylation of signaling proteins.To date,most of the work in OBs has focused on phosphorylation by tyrosyl kinases,but little has been revealed about dephosphorylation by protein tyrosine phosphatases(PTPases).SHP2(encoded by PTPN11)is a ubiquitously expressed PTPase.PTPN11 mutations are associated with both bone and cartilage manifestations in patients with Noonan syndrome(NS)and metachondromatosis(MC),although the underlying mechanisms remain elusive.Here,we report that SHP2 deletion in bone gamma-carboxyglutamate protein-expressing(Bglap+)bone cells leads to massive osteopenia in both trabecular and cortical bones due to the failure of bone cell maturation and enhanced osteoclast activity,and its deletion in Bglap+chondrocytes results in the onset of enchondroma and osteochondroma in aged mice with increased tubular bone length.Mechanistically,SHP2 was found to be required for osteoblastic differentiation by promoting RUNX2/OSTERIX signaling and for the suppression of osteoclastogenesis by inhibiting STAT3-mediated RANKL production by osteoblasts and osteocytes.These findings are likely to explain the compromised skeletal system in NS and MC patients and to inform the development of novel therapeutics to combat skeletal disorders. | Lijun Wang Huiliang Yang Jiahui Huang Shaopeng Pei Liyun Wang Jian Q.Feng Dian Jing Hu Zhao Henry M.Kronenberg Douglas C.Moore Wentian Yang | 2021 | Bone Research2021,9,1: | 3 |
| 5 | Synergistic effects of multiple driving factors on the runoff variations in the Yellow River Basin,China显示文摘River runoff plays an important role in watershed ecosystems and human survival,and it is controlled by multiple environmental factors.However,the synergistic effects of various large-scale circulation factors and meteorological factors on the runoff on different time-frequency scales have rarely been explored.In light of this,the underlying mechanism of the synergistic effects of the different environmental factors on the runoff variations was investigated in the Yellow River Basin of China during the period 1950-2019 using the bivariate wavelet coherence(WTC)and multiple wavelet coherence(MWC)methods.First,the continuous wavelet transform(CWT)method was used to analyze the multiscale characteristics of the runoff.The results of the CWT indicate that the runoff exhibited significant continuous or discontinuous annual and semiannual oscillations during the study period.Scattered inter-annual time scales were also observed for the runoff in the Yellow River Basin.The meteorological factors better explained the runoff variations on seasonal and annual time scales.The average wavelet coherence(AWC)and the percent area of the significant coherence(PASC)between the runoff and individual meteorological factors were 0.454 and 19.89%,respectively.The circulation factors mainly regulated the runoff on the inter-annual and decadal time scales with more complicated phase relationships due to their indirect effects on the runoff.The AWC and PASC between the runoff and individual circulation factors were 0.359 and 7.31%,respectively.The MWC analysis revealed that the synergistic effects of multiple factors should be taken into consideration to explain the multiscale characteristic variations of the runoff.The AWC or MWC ranges were 0.320-0.560,0.617-0.755,and 0.819-0.884 for the combinations of one,two,and three circulation and meteorological factors,respectively.The PASC ranges were 3.53%-33.77%,12.93%-36.90%,and 20.67%-39.34%for the combinations one,two,and three driving factors,respectively.The combinations of precipitation,evapotranspiration(or the number of rainy days),and the Arctic Oscillation performed well in explaining the variability in the runoff on all time scales,and the average MWC and PASC were 0.847 and 28.79%,respectively.These findings are of great significance for improving our understanding of hydro-climate interactions and water resources prediction in the Yellow River Basin. | WANG Junjie SHI Bing ZHAO Enjin CHEN Xuguang YANG Shaopeng | 2021 | Journal of Arid Land2021,13,8: | 3 |
| 6 | Ethylenediamine promoted the hydrogenative coupling of nitroarenes over Ni/C catalyst显示文摘Azobenzene and its derivatives are key raw materials and it is an environmentally friendly method for the preparation of azobenzene by hydrogenative coupling of nitrobenzene. The development of nickel based catalyst for organic transformations is of importance because of its relatively low cost and toxicity. In this work, we found that ethylenediamine can enrich the electron state of Ni and make the azobenzene easily desorb from the surface of the catalyst, which inhibits the hydrogenation of azobenzene to aniline. The selectivity of azobenzene is greatly improved. When the ratio of Ni and ethylenediamine is 1:10, the yield of the azobenzene can reach 95.5%. | Youdi Yang Shaopeng Li Chao Xie Hangyu Liu Yanyan Wang Qingqing Mei Huizhen Liu Buxing Han | 2019 | Chinese Chemical Letters2019,30,1: | 3 |
| 7 | Influence of Cr^(3+) Concentration on SO_2 Removal over TiO_2 Based Multi-walled Carbon Nanotubes显示文摘In this study, titanium dioxide supported by multi-walled carbon nano tubes(MWCNTs/TiO_2) and Cr-doped TiO_2 supported by MWCNTs(MWNTs/Cr-TiO_2) were synthesized by the sol-gel method. The prepared samples were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, the BrunauerEmmett-Teller analysis, and the Raman spectroscopy. The oxidation and efficiency for removal of SO_2 in a simulated flue gas were investigated experimentally in a fixed-bed reactor. The 15% MWCNTs/Cr-Ti02 sample displayed excellent adsorption properties, and a SO_2 removal rate equating to 30.415 1 mg/g from the simulated flue gas containing 2 300 μg/g of SO_2, 8% of 02, and 5% of H20 was achieved under optimal conditions covering a temperature of 333.15 K, and a space velocity of 1 275 h^(-1). The adsorption process was enhanced because Cr doping modified the pore structure and inhibited the grain growth of TiO_2. In addition, the Freundlich and Langmuir models revealed that SO_2 was mainly adsorbed through chemical adsorption on the sample surfaces, and the thermodynamic model analysis indicated that the adsorption was a spontaneous, exothermic, and entropy-reducing process. The adsorption kinetics of SO_2 can be described by the pseudosecond-order kinetic and the Bangham dynamics models. The possible reaction mechanism involved in desulfurization process was also proposed. | Yang Yanchun Jia Fengrui Jian Weiwei Zhang Shaopeng Ma Danzhu Liu Guangxin | 2019 | China Petroleum Processing & Petrochemical Technology2019,21,1: | 2 |
| 8 | Enhancing the power conversion efficiency of PCDTBT:PC_(71)BM polymer solar cells using a mixture of solvents显示文摘Organic polymer solar materials are shown to exhibit better solubility in mixed solvents than in pure ones,which affects the performance of their solar cells.In this article,poly[N-9-hepta-decanyl-2,7-carbazole-alt-5,5-(4.7-di-2-thienyI-2,l,3-benzothiadiazole)(PCDTBT0)and[6,6]-phenyl-C71-butyric acid methyl ester(PC_(71)BM)are used as active layer materials in solar cells.To optimize the performance of these active materials,the ratio of chloroform(CF)to chlorobenzene used as solvents to dissolve PCDTBT,and PC_(71)BM is varied,which is shown to affect power conversion efficiency(PCE).The solar cell that shows the best performance with a PCE as high as 6.82%is produced using a volume ratio of CF to chlorobenzene of1:1. | Shaopeng Yang Ye Zhang Tao Jiang Xuefeng Sun Chaoqun Lu Guang Li Xiaowei Li Guangsheng Fu | 2014 | Chinese Science Bulletin2014,59,3: | 2 |
| 9 | A hypothesis for crack free interior surfaces of Longyou caverns caved in argillaceous siltstone 2000 years ago显示文摘Five complete caverns were discovered in Longyou in 1992.They were manually caved in argillaceous siltstone at shallow depths more than 2000 years ago.When they were un-watered,their integrity was maintained completely,and their interior rock surfaces were free of old cracks.Since then,however,the rock's interior faces have initiated and propagated more and more cracks.This paper attempts to address the question of why the rock interior faces were free of old cracks once they were unearthed.To address this question,this paper proposes a hypothesis that the argillaceous siltstone has the ability of self-healing its cracks over a short period of time under weak acid water environment.Data and evidence are presented herewith to prove the hypothesis.They include observations and measurements in the field and test results in the laboratory.Specifically,a three-point bending test is used to form a tensile crack in a rectangular rock specimen and a deadload test for the specimen immersed in initially weak acid water is used for self-healing its crack.The results have shown that the argillaceous siltstone is in a state of weak alkalinity and the rain water at the site is in a state of weak acidity.Therefore,when it is immersed in weak acid water for some time,the argillaceous siltstone would be able to make chemical reactions to generate new minerals such as calcite.The new minerals would be able to infill the cracks and then heal the crack within a few years.Once the crack is self-healed,the rock can regain its strength and integrity.Consequently,the rock interior surfaces could be free of old cracks when the water was pumped out of the caverns. | Zhong Qi YUE Shaopeng FAN Zhifa YANG Lihui LI Luqing ZHANG Zhongjian ZHANG | 2010 | Frontiers of Structural and Civil Engineering2010,4,2: | 2 |
| 10 | Tectono-thermal evolution of the Liwan Sag, deepwater area in the Zhujiang River Mouth Basin, northern South China Sea显示文摘The Liwan Sag, with an area of 4 000 km^2, is one of the deepwater sags in the Zhujiang River(Pearl River) Mouth Basin, northern South China Sea. Inspired by the exploration success in oil and gas resources in the deepwater sags worldwide, we conducted the thermal modeling to investigate the tectono-thermal history of the Liwan Sag,which has been widely thought to be important to understand tectonic activities as well as hydrocarbon potential of a basin. Using the multi-stage finite stretching model, the tectonic subsidence history and the thermal history have been obtained for 12 artificial wells, which were constructed on basis of one seismic profile newly acquired in the study area. Two stages of rifting during the time periods of 49–33.9 Ma and 33.9–23 Ma can be recognized from the tectonic subsidence pattern, and there are two phases of heating processes corresponding to the rifting.The reconstructed average basal paleo-heat flow values at the end of the rifting events are ~70.5 and ~94.2 mW/m^2 respectively. Following the heating periods, the study area has undergone a persistent thermal attenuation phase since 23 Ma and the basal heat flow cooled down to ~71.8–82.5 mW/m^2 at present. | TANG Xiaoyin HUANG Shaopeng YANG Shuchun JIANG Guangzheng JI Mo HU Shengbiao | 2018 | Acta Oceanologica Sinica2018,37,2: | 2 |
| 11 | Bi_(2)O_(2)Se/BP van der Waals heterojunction for high performance broadband photodetector显示文摘Broadband photodetector has wide applications in the field of remote sensing,health monitoring and medical imaging.Two-dimensional(2D)materials with narrow bandgaps have shown enormous potential in broadband photodetection.However,the device performance is often restricted by the high dark currents.Herein,we demonstrate a high performance broadband photodetector by constructing Bi_(2)O_(2) Se/BP van der Waals heterojunction.The device exhibits a p-n diode behavior with a current rectification ratio of~20.Benifited from the low dark current of the heterojunction and the effective carrier separation,the device achieves the responsivity(R)of~500 A/W,~4.3 A/W and~2.3 A/W at 700 nm,1310 nm and 1550 nm,respectively.The specific detectivity(D^(*))is up to~2.8×10^(11) Jones(700 nm),~2.4×10^(9) Jones(1310 nm)and~1.3×10^(9) Jones(1550 nm).Moreover,the response time is~9 ms,which is more than 20 times faster than that of individual BP(~190 ms)and Bi_(2)O_(2)Se(~180 ms)devices. | Xing LIU Wenhui WANG Fang YANG Shaopeng FENG Zhenliang HU Junpeng LU Zhenhua NI | 2021 | Science China(Information Sciences)2021,64,4: | 2 |
| 12 | Global patterns and climatic drivers of above-and belowground net primary productivity in grasslands显示文摘Understanding patterns and determinants of net primary productivity(NPP)in global grasslands is ongoing challenges,especially for belowground NPP(BNPP)and its fraction(fBNPP).By developing a comprehensive field-based dataset,we revealed that,along with gradients of mean annual precipitation,actual evapotranspiration,and aridity,aboveground NPP(ANPP),BNPP,and total NPP(TNPP)exhibited hump-shaped patterns,whereas fBNPPshowed an opposite trend.ANPP and TNPP showed positive correlations with mean annual temperature,but fBNPPwas negatively correlated with it.The relationship between BNPP and climatic factors was considerably weak,indicating that BNPP was relatively stable regardless of the climate conditions.We also observed that the sensitivities of ANPP and BNPP to interannual temperature variability and those of BNPP to interannual precipitation fluctuations exhibited large variations among different study sites,and differed from those at the spatial scale.In contrast,the temporal sensitivities of ANPP to interannual precipitation variability were highly similar across all the individual sites and much smaller than those at the spatial scale.Overall,these results highlight that precipitation,temperature and evapotranspiration all play vital roles in shaping ANPP pattern and its partitioning to belowground and that the patterns of BNPP along climatic gradients do not mirror those of the ANPP. | Yuanfeng Sun Yuanhe Yang Xia Zhao Zhiyao Tang Shaopeng Wang Jingyun Fang | 2021 | Science China(Life Sciences)2021,64,5: | 2 |
