| 1 | Unraveling the role of Ti3C2 MXene underlayer for enhanced photoelectrochemical water oxidation of hematite photoanodes显示文摘Hematite is regarded as a promising photoanode for photoelectrochemical(PEC) water splitting.However,the charge recombination occurred at the interface of FTO/hematite strictly limits the PEC performance of hematite.Herein,we reported a Ti3C2 MXene underlayer modified hematite(Ti-Fe2O3) photoanode via a simple drop-casting followed by hydrothermal and annealing processes.Owing to the bifunctional role of Ti3C2 MXene underlayer in improving the interfacial properties of FTO/hematite and providing Ti source for the construction of Fe2 TiO5/Fe2O3 heterostructure in hematite nanostructure,the bulk and interfacial charge transfer dynamics of hematite are significantly enhanced,and consequently enhancing the PEC performance.Compared with the pristine hematite,the as-prepared Ti-Fe2O3 photoanode shows an increased photocurrent density from 0.80 mA/cm^(2) to 1.30 mA/cm^(2) at 1.23 V vs.RHE.Moreover,a further promoted PEC performance including a dramatically increased photocurrent density of 2.49 mA/cm^(2) at1.23 V vs.RHE and an obviously lowered onset potential is achieved for the Ti-Fe2O3 sample after the subsequent surface F-treatment and the loading of FeNiOOH cocatalyst.Such results suggest that the introduction of Ti3C2 MXene underlayer is a facile but effective approach to improve the PEC water splitting activity of hematite. | Haiyan Ji Shan Shao Guotao Yuan Cheng Lu Kun Feng Yujian Xia Xiaoxin Lv Jun Zhong Hui Xu Jiujun Deng | 2021 | Journal of Energy Chemistry2021，30，1： | 1 |

| 3 | International Meridian Circle Program显示文摘The Earth is buffered from the ferocious onslaught of the solar wind by a thin layer of matter known as the atmosphere and geospace.This layer absorbs energy from irradiance and outburst from the Sun,as well as from disasters,transient phenomena and anthropogenic emissions originated from Earth.Through complicated physics,the absorbed energy changes the atmospheric and geospace state and sometimes gets re-released to power extreme events such as space weather.Taking place globally,these complicated processes cannot be understood unless they are studied globally.The Chinese scientists have proposed the International Meridian Circle Program(IMCP)to meet this demand.By operating nearly 1000 instruments encompassing all latitudes along with the 120°E–60°W longitudes,IMCP aims,for the first time,to construct comprehensive 3D data representation of the atmosphere and geospace on a global scale and empower interdisciplinary research to tackle key questions related to Earth’s environment and climate change. | LIU William WANG Chi SHEN Xuhui WU Jian BLANC Michel YAN Yihua FU Suiyan YUE Xinan LEI Jiuhou GONG Wei ZHANG Shaodong ZHANG Qinghe WANG Xin YANG Jing ZHANG Xiaoxin GAO Jing XU Jiyao YANG Guotao LI Hui REN Liwen YANG Fang | 2020 | 空间科学学报2020，40，5： | 1 |
| 4 | Spatial dynamics of Chinese Muntjac related to past and future climate fluctuations显示文摘Climate fluctuations in the past and in the future are likely to result in population expansions,shifts,or the contraction of the ecological niche of many species,and potentially leading to the changes in their geographical distributions.Prediction of suitable habitats has been developed as a useful tool for the assessment of habitat suitability and resource conservation to protect wildlife.Here,we model the ancestral demographic history of the extant modern Chinese Muntjac Muntiacus reevesi populations using approximate Bayesian computation(ABC)and used the maximum entropy model to simulate the past and predict the future spatial dynamics of the species under climate oscillations.Our results indicated that the suitable habitats for the M.reevesi shifted to the Southeast and contracted during the Last Glacial Maximum,whereas they covered a broader more northern position in the Middle Holocene.The ABC analyses revealed that the modern M.reevesi populations diverged in the Middle Holocene coinciding with the significant contraction of the highly suitable habitat areas.Furthermore,our predictions suggest that the potentially suitable environment distribution for the species will expand under all future climate scenarios.These results indicated that the M.reevesi diverged in the recent time after the glacial period and simultaneously as its habitat's expanded in the Middle Holocene.Furthermore,the past and future climate fluctuation triggered the change of Chinese muntjac spatial distribution,which has great influence on the Chinese muntjac's population demographic history. | Zhonglou Sun Pablo Orozco-terWengel Guotao Chen Ruolei Sun Lu Sun Hui Wang Wenbo Shi Baowei Zhang | 2021 | Current Zoology2021，67，4： | 0 |
| 5 | A SIMPLE METHOD FOR PREDICTION OF THE REDUCED SCATTERING COEFFICIENT IN TISSUE-SIMULATING PHANTOMS显示文摘This paper proposes a method for predicting the reduced scattering coefficients of tissuesimulating phantoms or the desired amount of scatters for producing phantoms according to Mie scattering theory without measurements with other instruments.The concentration of the scatters TiO2 particles is determined according to Mie theory calculation and added to transparent host epoxy resin to produce phantoms with different reduced scattering coefficients.Black India Ink is added to alter the absorption coefficients of the phantoms.The reduced scattering coefficients of phantoms are measured with single integrating sphere system.The results show that the measurements are in direct proportion to the concentration of TiO2 and have identical with Mie theory calculation at multiple wavelengths.The method proposed can accurately determine the concentration of scatters in the phantoms to ensure the phantoms are qualified with desired reduced scattering coefficients at specified wavelength.This investigation should be possible to manufacture the phantom simply in reasonably accurate for evaluation of biomedical optical imaging systems. | JIANWEI FU GUOTAO QUAN HUI GONG | 2010 | Journal of Innovative Optical Health Sciences2010，3，1： | 0 |
