| 1 | Synthesis and electrochemical performance of LiMnPO_4 /C composites cathode materials显示文摘LiMnPO_4 /C composites were synthesized via solid-state reaction with different carbon sources: sucrose, citric acid and oxalic acid. The sam- ples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical performance test. The results of XRD reveal that carbon coating has no effect on the phase of LiMnPO_4 . The LiMnPO_4 /C synthesized at 600 °C with citric acid as carbon source shows an initial discharge capacity of 117.8 mA·hg^-1 at 0.05 C rate. After 30 cycles, the capacity remains 98.2 mAh·g^-1 . The improved electrochemical properties of LiMnPO_4 /C is attributed to the decomposition of organic acid during the sintering process. | ZHONG Shengkui XU Yuebin LI Yanhong ZENG Honghu LI Wei WANG Jian | 2012 | Rare Metals2012，31，5： | 4 |
| 2 | Experimental study on the deformation and failure mechanism of overburden rock during coal mining using a comprehensive intelligent sensing method显示文摘Understanding the spatiotemporal evolution of overburden deformation during coal mining is still a challenge in engineering practice due to the limitation of monitoring techniques. Taking the Yangliu Coal Mine as an example, a similarity model test was designed and conducted to investigate the deformation and failure mechanism of overlying rocks in this study. Distributed fiber optic sensing(DFOS), highdensity electrical resistivity tomography(HD-ERT) and close-range photogrammetry(CRP) technologies were used in the test for comprehensive analyses. The combined use of the three methods facilitates the investigation of the spatiotemporal evolution characteristics of overburden deformation, showing that the mining-induced deformation of overburden strata was a dynamic evolution process. This process was accompanied by the formation, propagation, closure and redevelopment of separation cracks.Moreover, the key rock stratum with high strength and high-quality lithology played a crucial role in the whole process of overburden deformation. There were generally three failure modes of overburden rock layers, including bending and tension, overall shearing, and shearing and sliding. Shear failure often leads to overburden falling off in blocks, which poses a serious threat to mining safety. Therefore, realtime and accurate monitoring of overburden deformation is of great significance for the safe mining of underground coal seams. | Gang Cheng Wentao Xu Bin Shi Jinghong Wu Binyang Sun Honghu Zhu | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，5： | 2 |
| 3 | Determination of phase diagrams using the diffusion couple technique显示文摘It has been demonstrated that the diffusion couple technique is a powerful and efficient approach in establishing phase relationships of ternary systems. Accurate data on the phase equilibria can be obtained if the appropriate alloys are employed as end members of the diffusion couple. It is desirable to combine the diffusion couple technique with an investi- gation of the afterwards selected equilibrated alloys so that the precision and reliability of the obtained information about a ternary isotherm could be guaranteed. | XU Honghu DU Yong ZHOU Yichun JIN Zhanpeng | 2006 | Rare Metals2006，25，5： | 1 |
| 4 | Establishment of a humanized mouse model using steady-state peripheral blood-derived hematopoietic stem and progenitor cells facilitates screening of cancer-targeted T-cell repertoires显示文摘Background:Cancer-targeted T-cell receptor T(TCR-T)cells hold promise in treating cancers such as hematological malignancies and breast cancers.However,approaches to obtain cancer-reactive TCR-T cells have been unsuccessful.Methods:Here,we developed a novel strategy to screen for cancer-targeted TCR-T cells using a special humanized mouse model with person-specific immune fingerprints.Rare steady-state circulating hematopoietic stem and progenitor cells were expanded via three-dimensional culture of steady-state peripheral blood mononuclear cells,and then the expanded cells were applied to establish humanized mice.The human immune system was evaluated according to the kinetics of dendritic cells,monocytes,T-cell subsets,and cytokines.To fully stimulate the immune response and to obtain B-cell precursor NAML-6-and triple-negative breast cancer MDA-MB-231-targeted TCR-T cells,we used the inactivated cells above to treat humanized mice twice a day every 7 days.Then,human T cells were processed for TCRβ-chain(TRB)sequencing analysis.After the repertoires had been constructed,features such as the fraction,diversity,and immune signature were investigated.Results:The results demonstrated an increase in diversity and clonality of T cells after treatment.The preferential usage and features of TRBV,TRBJ,and the V–J combination were also changed.The stress also induced highly clonal Science and Technology,Grant/Award Number:2021C03010;Zhejiang Provincial Natural Science Foundation of China,Grant/Award Numbers:LTGY24H080003,LY21H080004 expansion.Tumor burden and survival analysis demonstrated that stress induction could significantly inhibit the growth of subsequently transfused live tumor cells and prolong the survival of the humanized mice.Conclusions:We constructed a personalized humanized mouse model to screen cancer-targeted TCR-T pools.Our platform provides an effective source of cancer-targeted TCR-T cells and allows for the design of patient-specific engineered T cells.It therefore has the potential to greatly benefit cancer treatment. | Yulin Xu Wei Shan Qian Luo Meng Zhang Dawei Huo Yijin Chen Honghu Li Yishan Ye Xiaohong Yu Yi Luo He Huang | 2024 | Cancer Innovation2024，3，3： | 0 |
| 5 | Efficient expansion of rare human circulating hematopoietic stem/progenitor cells in steady-state blood using a polypeptide-forming 3D culture显示文摘Although widely applied in treating hematopoietic malignancies,transplantation of hematopoietic stem/progenitor cells(HSPCs)is impeded by HSPC shortage.Whether circulating HSPCs(cHSPCs)in steady-state blood could be used as an alternative source remains largely elusive.Here we develop a three-dimensional culture system(3DCS)including arginine,glycine,aspartate,and a series of factors.Fourteen-day culture of peripheral blood mononuclear cells(PBMNCs)in 3DCS led to 125-and 70-fold increase of the frequency and number of CD34+cells.Further,3DCS-expanded cHSPCs exhibited the similar reconstitution rate com-pared to CD34+HSPCs in bone marrow.Mechanistically,3DCS fabricated an immunomodulatory niche,secreting cytokines as TNF to support cHSPC survival and proliferation.Finally,3DCS could also promote the expansion of cHSPCs in patients who failed in HSPC mobilization.Our 3DCS successfully expands rare cHSPCs,providing an alternative source for the HSPC therapy,particularly for the patients/donors who have failed in HSPC mobilization. | Yulin Xu Xiangjun Zeng Mingming Zhang Binsheng Wang Xin Guo Wei Shan Shuyang Cai Qian Luo Honghu Li Xia Li Xue Li Hao Zhang Limengmeng Wang Yu Lin Lizhen Liu Yanwei Li Meng Zhang Xiaohong Yu Pengxu Qian He Huang | 2022 | Protein & Cell2022，13，11： | 0 |
