| 1 | A Method for Alpine Wetland Delineation and Features of Border: Zoigê Plateau, China显示文摘Accurate wetland delineation is the basis of wetland definition and mapping, and is of great importance for wetland management and research. The Zoigê Plateau on the Qinghai-Tibet Plateau was used as a research site for research on alpine wetland delineation. Several studies have analyzed the spatiotemporal pattern and dynamics of these alpine wetlands, but none have addressed the issues of wetland boundaries. The objective of this work was to discriminate the upper boundaries of alpine wetlands by coupling ecological methods and satellite observations. The combination of Landsat 8 images and supervised classification was an effective method for rapid identification of alpine wetlands in the Zoigê Plateau. Wet meadow was relatively stable compared with hydric soils and wetland hydrology and could be used as a primary indicator for discriminating the upper boundaries of alpine wetlands. A slope of less than 4.5° could be used as the threshold value for wetland delineation. The normalized difference vegetation index(NDVI) in 434 field sites showed that a threshold value of 0.3 could distinguish grasslands from emergent marsh and wet meadow in September. The median normalized difference water index(NDWI) of emergent marsh remained more stable than that of wet meadow and grasslands during the period from September until July of the following year. The index of mean density in wet meadow zones was higher than the emergent and upland zones. Over twice the number of species occurred in the wet meadow zone compared with the emergent zone, and close to the value of upland zone. Alpine wetlands in the three reserves in 2014 covered 1175.19 km2 with a classification accuracy of 75.6%. The combination of ecological methods and remote sensing technology will play an important role in wetland delineation at medium and small scales. The correct differentiation between wet meadow and grasslands is the key to improving the accuracy of future wetland delineation. | ZHENG Yaomin NIU Zhenguo GONG Peng LI Mengna HU Lile WANG Lei YANG Yuxiang GU Hai-jun MU Jinrong DOU Gejia XUE Hui WANG Lin LI Hua DOU Gejie DANG Zhicairang | 2017 | Chinese Geographical Science2017，27，5： | 2 |

| 3 | Surface coatings of two-dimensional metal-organic framework nanosheets enable stable zinc anodes显示文摘Aqueous zinc-ion batteries (ZIBs) have been considered as safe and scalable energy storage solutions,but the dendrite and corrosion issues of Zn anodes have hindered their further application.Herein,we demonstrate that two-dimensional metalorganic framework (MOF) nanosheets can act as protective coatings to prevent dendrite formation and hydrogen evolution of Zn anodes.The morphology of MOFs was tuned from octahedral nanoparticles (UiO-67-3D) to nanosheets (UiO-67-2D),leading to significantly enhanced protective performance.UiO-67-2D nanosheets-coated Zn anodes displayed smaller polarization,longer cycling lifetime and lower H_(2) evolution than those of UiO-67-3D nanoparticles in symmetrical cells,which has been attributed to the higher concentration of surface Zr-OH/H_(2)O to induce uniform Zn deposition and one-dimensional (1D) channels perpendicular to the Zn surface to regulate Zn^(2+) diffusion.The assembled UiO-67-2D@Zn||Mn_(2)O_(3)/C full cell shows a high capacity of240 m Ah g^(-1)at 1 A g^(-1) and excellent cycling stability. | Liling Lei Feifan Chen Yulun Wu Jian Shen Xue-Jun Wu Shishan Wu Shuai Yuan | 2022 | Science China Chemistry2022，65，11： | 0 |
| 4 | Dual inhibition of glucose uptake and energy supply synergistically restrains the growth and metastasis of breast cancer显示文摘Metastatic breast cancer(MBC) is one of the most common and knotty diseases in female population which could place them in a life-threatening condition. For malignant proliferation and migration, cancer cells require a large amount of glucose and energy to meet the demand of rapid metabolism. Hence,efficiently diminishing the utilization of energy substances by cancer cells is emerging as validated therapeutic strategies for cancer therapy. Herein, a nanoplatform with dual-inhibition of glucose uptake and oxidative phosphorylation(OXPHOS) was designed, which consisted of albendazole(ABZ) and atovaquone(ATO) by simple carrier-free self-assembling. The introduction of ABZ could evidently decrease glucose uptake to reduce the main “energy fuel” of cancer cells. Meanwhile, as a blocker of OXPHOS, ATO would reduce adenosine triphosphate(ATP) production and ameliorate hypoxia microenvironment by suppressing mitochondrial respiratory chain. Under such dual inhibition of energy metabolism, AA NPs exerted synergistic energy exhaustion effect and outstanding hypoxia improvement function, efficiently inhibiting tumor growth and metastasis. This research not only illustrates the feasibility of energy metabolism therapy by co-inhibiting glucose uptake and OXPHOS, but also provides an ingenious tactic to diminish metastasis during MBC treatment. | Yuan Xu Liling Huang Yuyang Bi Qi Song Mengmeng Zhang Lingfeng Zhang Tianjiao Zhou Lei Xing Hulin Jiang | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
