| 1 | Processes of coastal ecosystem carbon sequestration and approaches for increasing carbon sink显示文摘The oceans are the largest carbon pools on Earth, and play the role of a 'buffer' in climate change. Blue carbon, the carbon(mainly organic carbon) captured by marine ecosystems, is one of the important mechanisms of marine carbon storage.Blue carbon was initially recognized only in the form of visible coastal plant carbon sequestration. In fact, microorganisms(phytoplankton, bacteria, archaea, viruses, and protozoa), which did not receive much attention in the past, account for more than 90% of the total marine biomass and are the main contributors to blue carbon. Chinese coastal seas, equivalent to 1/3 of China's total land area, have a huge carbon sink potential needing urgently research and development. In this paper, we focus on the processes and mechanisms of coastal ocean's carbon sequestration and the approaches for increasing that sequestration. We discuss the structures of coastal ecosystems, the processes of carbon cycle, and the mechanisms of carbon sequestration. Using the evolution of coastal ocean's carbon sinks in sedimentary records over geologic times, we also discuss the possible effects of natural processes and anthropogenic activities on marine carbon sinks. Finally, we discuss the prospect of using carbon sequestration engineering for increasing coastal ocean's carbon storage capacity. | ZHANG Yao ZHAO MeiXun CUI Qiu FAN Wei QI JiaGuo CHEN Ying ZHANG YongYu GAO KunShan FAN JingFeng WANG GuangYi YAN ChongLing LU HaoLiang LUO YaWei ZHANG ZiLian ZHENG Qiang XIAO Wei JIAO NianZhi | 2017 | Science China Earth Sciences2017,60,5: | 6 |
| 2 | Spirolindemers A and B,Lindenane Sesquiterpenoid Oligomers Equipped with Oxaspiro[4.5]decane from Chloranthus henryi显示文摘Spirolindemers A and B,unprecedented lindenane sesquiterpenoid dimer(1)and trimer(2)equipped with oxaspiro[4.5]decane unit,were discovered from the medicinal plant Chloranthus henryi.Their structures including absolute configurations were achieved by HRMS,NMR,ECD,X-ray diffraction analyses,and quantum chemical calculations.Biogenetically,hetero-and homo-Diels-Alder additions may dominate the formation of oxaspiro[4.5]decane and spiro[4.5]decane skeletons,respectively.Compound 1 showed anti-inflammatory activity by inhibiting the expression of iNOS and COX-2. | Jixin Li Jun Chi Pengfei Tang Yunpeng Sun Weijia Lu Wenjun Xu Yongyue Wang Jun Luo Lingyi Kong | 2022 | Chinese Journal of Chemistry2022,40,5: | 4 |
| 3 | Oxide transformation and break-up of liquid metal in boiling solutions显示文摘The non-toxic gallium-based liquid metals(LMs) are promising for various newly emerging areas due to having excellent fluidity, high electrical and heat conductivity. However, the oxide layers often affect their applications. In this paper, we disclosed a straightforward boiling strategy to efficiently remove the oxide of LM in deionized water. Meanwhile such method was also demonstrated to be capable of quickly breaking up LM into droplets(mean 0.51 mm, SD 0.20 mm) in Na Cl solution,which has important value for manufacture purpose. According to the force analysis, surface tension of LM dominates the interaction between solution bubbles and LM under the same heating conditions. Then we characterized the surface morphology and compositions of LM droplets boiled(LMDB) using scanning electron microscope(SEM), X-ray diffraction(XRD) and Xray photoelectron spectroscopy(XPS) and tested the dynamic force between a rod and LMDB. It was shown that after being boiled in water, most of Ga2O3 was transformed to scattered α-Ga OOH nanorods which has less restriction to the deformation of LM and large resistance force(0.8 mN) was tested;otherwise, after boiled in Na Cl solution, more Ga2 O3 with contact patch structure reduces the surface resistance of LM(0.2 m N) and makes it to be broken up by bubbles. The different surface products are determined by the inhibition of hydrolysis of Ga3+by Na Cl solution. This study paved a simple way for oxide removal in neutral solution and mass production of LMD. It also suggests an efficient approach for exploring mechanisms of interactions between LM and bubbles, which is difficult to study otherwise in sonication. | YANG LiXiang ZHAO Xi XU Shuo LU YongYu CHANG Hao LIU Jing | 2020 | Science China(Technological Sciences)2020,63,2: | 3 |

| 9 | The relationship between zinc deficiency and infectious complications in patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background The prevalence of zinc deficiency is high in patients with chronic liver disease,but few studies have hitherto explored the relationship between the serum zinc level and hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF).This study aimed to assess the association between zinc deficiency and infectious complications,and model for end-stage liver disease(MELD)score in patients with HBV-related ACLF.Methods Patients with HBV-related ACLF from the Department of Infectious Diseases of the Third Affiliated Hospital of Sun Yat-sen University(Guangzhou,China)between January 2019 and December 2019 were retrospectively analysed in this study.Their demographic,clinical,and laboratory data were retrieved from the hospital information system and analysed.The Student’s t-test was used for normally distributed continuous variables between two groups and the Chi-square test was used for categorical data.Univariate and multivariate logistic regression analyses were applied to identify independent parameters.Results A total of 284 patients were included in this study,including 205 liver cirrhosis and 79 non-cirrhosis patients.The proportion of patients with zinc deficiency was the highest(84.5%),followed by subclinical zinc deficiency(14.1%)and normal zinc level(1.4%).Patients in the zinc deficiency group had a higher MELD score than the subclinical zinc deficiency or normal zinc group(P=0.021).Age,total bilirubin,and serum zinc level were independent factors for infection(P_(s)<0.05).The serum zinc level in patients without complications at admission was significantly higher than that in patients with complications(P=0.004).Moreover,the serum zinc level in patients with prothrombin time activity(PTA)of<20%was significantly lower than that in patients with 20%≤PTA<30%(P=0.007)and that in patients with 30%≤PTA<40%(P<0.001).Conclusions Zinc deficiency is common in patients with HBV-related ACLF.Zinc deficiency is closely associated with infectious complications and MELD score in patients with HBV-related ACLF. | Xinhua Li Lu Wang Na He Yeqiong Zhang Jiahui Pang Heping Wang Meng Yu Yongyu Mei Liang Peng Wenxiong Xu | 2022 | Gastroenterology Report2022,10,1: | 0 |
