| 1 | Detection of Acid Rain Stress Effect on Plant Using Hyperspectral Data in Three Gorges Region,China显示文摘This paper aims to use hyperspectral data to detect the spectral change caused by acid stress to a native forest type in the Three Gorges region of China. For this purpose, a ground-based hyperspectral experiment was conducted at the Three Gorges region to detect acid deposition that caused Masson pine (Pinus massoniana) forest degra-dation. Continuum removal method was used to isolate wavebands more responsive to stress in wavelengths 450-750nm. The differences in chlorophyll concentrations and needle thickness caused by acidic stress are found to be explicable to the different spectral reflectance patterns in the visible and near-infrared wavelengths. Two new chlorotic indices were utilized to explain the stress-caused leaf chlorosis. The comparison of simulated vegetation indices and principal component analysis (PCA) results suggests that it would be possible to monitor acid rain stress effect on forest ecosystem from some wider spectral regions. | SONG Xiaodong JIANG Hong YU Shuquan ZHOU Guomo | 2008 | Chinese Geographical Science2008，18，3： | 7 |
| 2 | Optimal Planning of Community Integrated Energy Station Considering Frequency Regulation Service显示文摘With the extensive integration of high-penetration renewable energy resources,more fast-response frequency regulation(FR)providers are required to eliminate the impact of uncertainties from loads and distributed generators(DGs)on system security and stability.As a high-quality FR resource,community integrated energy station(CIES)can effectively respond to frequency deviation caused by renewable energy generation,helping to solve the frequency problem of power system.This paper proposes an optimal planning model of CIES considering FR service.First,the model of FR service is established to unify the time scale of FR service and economic operation.Then,an optimal planning model of CIES considering FR service is proposed,with which the revenue of participating in the FR service is obtained under market mechanism.The flexible electricity pricing model is introduced to flatten the peak tieline power of CIES.Case studies are conducted to analyze the annual cost and the revenue of CIES participating in FR service,which suggest that providing ancillary services can bring potential revenue. | Cheng Li Peng Li Hao Yu Hailong Li Jinli Zhao Shuquan Li Chengshan Wang | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，2： | 7 |
| 3 | Simultaneous removal of gaseous CO and elemental mercury over Cu-Co modified activated coke at low temperature显示文摘Cu-Co multiple-oxides modified on HNO_3-pretreated activated coke(AC_(N))were optimized for the simultaneous removal of gaseous CO and elemental mercury(Hg^(0))at low temperature(<200℃).It was found that 2%CuOx-10%CoOx/AC_(N)catalyst calcined at 400℃resulted in the coexistence of complex oxides including CuO,Cu_2 O,Co_(3)O_(4,Co_(2)O_(3)and CoO phases,which might be good for the simultaneous catalytic oxidation of CO by Co-species and removal of Hg^(0)by Cu-species,benefiting from the synergistic catalysis during the electrointeraction between Go and Cu cations(CoO■Co_(3)O_(4)and Cu_(2)O■CuO).The catalysis removal of CO oxidation was obviously depended on the reaction temperature obtaining94.7%at 200℃,while no obvious promoting effect on the Hg^(0)removal(68.3%-78.7%).These materials were very substitute for the removal of CO and Hg^(0)from the flue gas with the conditions of 8-20 vol.%O_(2)and flue-gas temperature below 200℃.The removal of Hg^(0)followed the combination processes of adsorption and catalytic oxidation reaction via LangmuirHinshelwood mechanism,while the catalysis of CO abided by the Mars-van Krevelen mechanism with lattice oxygen species. | Fengyu Gao Hao Yan Xiaolong Tang Honghong Yi Shunzheng Zhao Qingjun Yu Shuquan Ni | 2021 | Journal of Environmental Sciences2021，33，3： | 3 |
| 4 | Tuning Interface Bridging Between MoSe2 and Three‑Dimensional Carbon Framework by Incorporation of MoC Intermediate to Boost Lithium Storage Capability显示文摘Interface engineering has been widely explored to improve the electrochemical performances of composite electrodes,which governs the interface charge transfer,electron transportation,and structural stability.Herein,MoC is incorporated into MoSe2/C composite as an intermediate phase to alter the bridging between MoSe2-and nitrogen-doped three-dimensional(3D)carbon framework as MoSe2/MoC/N–C connection,which greatly improve the structural stability,electronic conductivity,and interfacial charge transfer.Moreover,the incorporation of MoC into the composites inhibits the overgrowth of MoSe2 nanosheets on the 3D carbon framework,producing much smaller MoSe2 nanodots.The obtained MoSe2 nanodots with fewer layers,rich edge sites,and heteroatom doping ensure the good kinetics to promote pseudo-capacitance contributions.Employing as anode material for lithium-ion batteries,it shows ultralong cycle life(with 90%capacity retention after 5000 cycles at 2 A g−1)and excellent rate capability.Moreover,the constructed LiFePO4//MoSe2/MoC/N–C full cell exhibits over 86%capacity retention at 2 A g−1 after 300 cycles.The results demonstrate the effectiveness of the interface engineering by incorporation of MoC as interface bridging intermediate to boost the lithium storage capability,which can be extended as a potential general strategy for the interface engineering of composite materials. | Jing Chen Yilin Luo Wenchao Zhang Yu Qiao Xinxin Cao Xuefang Xie Haoshen Zhou Anqiang Pan Shuquan Liang | 2020 | Nano-Micro Letters2020，12，12： | 1 |

| 6 | Au atoms doped in Ti_(3)C_(2)T_(x)MXene:Benefiting recovery of oxygen vacancies towards photocatalytic aerobic oxidation显示文摘Photocatalytic aerobic oxidation by using oxygen molecules(O_(2))as green and low-cost oxidants is of great attraction,where the introduction of irradiation has been proved as an efficient strategy to lower reaction temperature as well as promote catalytic performance.Moreover,the oxygen vacancies(OVs)of catalyst are highly active sites to adsorb and activate O_(2)during photocatalytic aerobic oxidation.However,OVs are easily blocked by oxygen atoms from active oxygen species during the catalytic process,leading to the deactivation of catalysis.Herein,a promising catalyst toward photocatalytic aerobic oxidation was successfully developed by recovering the OVs through doping Au atoms into Ti_(3)C_(2)T_(x)MXene(Au/Ti_(3)C_(2)T_(x)).Impressively,Au/Ti_(3)C_(2)T_(x)exhibited remarkable activity under full-spectrum irradiation towards photooxidation of methyl phenyl sulfide(MPS)and methylene blue(MB),attaining a conversion of>90%at room temperature.Moreover,Au/Ti_(3)C_(2)T_(x)also manifested remarkable stability by maintaining>95%initial activity after 10 successive reaction rounds.Further mechanistic studies indicated that the OVs of Au/Ti_(3)C_(2)T_(x)served as the active centers to efficiently adsorb and activate O_(2).More importantly,the doped Au atoms of Au/Ti_(3)C_(2)T_(x)were conducive to the recovery of OVs during photocatalytic process from the results of theoretical and experimental aspects.The recovered OVs of Au/Ti_(3)C_(2)T_(x)continuously and efficiently activated O_(2),directly contributing to the remarkable catalytic activity and stability. | Kaifu Yu Sanmei Wang Qi Li Tingting Hou Yue Xin Rong He Wenhua Zhang Shuquan Liang Liangbing Wang Wenkun Zhu | 2022 | Nano Research2022，15，4： | 1 |
| 7 | A novel cerrobend block in the radiation therapy显示文摘This study was carried out to look for the substitute products of lead cerrobend block and determine whether the products can give more radiation dose to the tumor in the skin and superficial tumors in radiotherapy treatment.Five kinds of PbO/Er2O3/Epoxy(E-51) samples used as the cerrobend block in the electron beam radiotherapy treatment were prepared success-fully by a solidified forming approach.The central axis depth dose and off-axis dose profiles in the water phantom were calcu-lated using BEAMnrc/DOSEXYZnrc user codes.The results revealed that there were more energy deposition events induced by low energy electron beams in the surface of the water phantom.These electron beams were attributed to Compton scattering and photoemission between photons and erbium,plumbum elements.The maximum dose(Dm) and the depth at the maximum dose(Rm) were linearly dependent on the mass fraction of erbium and plumbum element in the sample.The max dose and its depth varied depending on the combined actions of new electrons and transmission electrons. | CHANG ShuQuan ZHANG Yu DONG Yu ZHANG HongXu DAI YaoDong | 2012 | Science China(Technological Sciences)2012，55，1： | 0 |
| 8 | 丛枝菌根真菌对其宿主光合能力、抗氧化酶和渗透物质积累的促进作用及其抗酸雨机制的探讨显示文摘酸雨在中国南方发生频繁,对亚热带树种生长具有明显抑制作用。以往研究表明,丛枝菌根真菌(AM真菌)可以缓解酸雨对宿主植物的胁迫效应。榉树(Zelkova serrata)为中国南方主要经济树种之一,其如何与共生AM真菌协同、增强其抗酸雨胁迫的能力是本项研究所要探讨的关键科学问题。通过温室控制实验,将榉树幼苗随机接受4个水平的AM真菌接种处理(接种灭菌菌种:单独接种Rhizophagus intraradices:单独接种Diversispora versiformis;接种这两种菌种的混合菌种)和3个pH水平(pH2.5、pH4.0和pH5.6)的硫酸型酸雨和硝酸型酸雨处理组成的12个处理组合,同时测定其生长、光合性能、抗氧化酶、渗透调节和土壤酶的响应格局。研究发现酸雨处理显著降低了非菌根榉树幼苗的总干重、总叶绿素含量、叶片净光合速率和可溶性蛋白的含量:接种AM真菌,特别是接种混合菌种,显著提高了强酸胁迫下榉树幼苗的总干重、光合性能、丙二醛、过氧化物酶、超氧化物歧化酶、可溶性蛋白和根系酸性磷酸酶活性。此外,菌根效应依赖于AM真菌的种类和酸胁迫的梯度。本研究结果表明,AM真菌对榉树幼苗抗酸胁迫的调控作用主要源于调节宿主植株光合能力、抗氧化酶和渗透物质的积累。树与其共生AM真菌在应对酸胁迫上协同机制的解析为该树种在中国南方酸雨区的栽培提供理论基础、具有重要的实践指导意义。 | Yanhong Wang Changliang Shao Yajing Qiu Shuquan Yu Lina Xia Xiaobin He Aiping Wu Naili Zhang | 2022 | Journal of Plant Ecology2022，15，5： | 0 |
