| 1 | Rb-Sr and Sm-Nd Isochron Ages of the Dongmozhazhua and Mohailaheng Pb-Zn Ore Deposits in the Yushu area, southern Qinghai and Their Geological Implications显示文摘Located on the northeast margin of the Qiangtang terrane between the Jinshajiang suture zone and Bangonghu-Nujiang suture zone, the Dongmozhazhua and Mohailaheng Pb-Zn deposits in the Yushu area of Qinghai Province are representative Pb-Zn deposits of the Pb-Zn-Cu polymetallic mineralization belt in the northern part of the Nujiang-Lancangjiang-Jinshajiang area, which are in the front belt of the Yushu thrust nappe system. The formed environments of these two deposits are different from those of sediment-hosted base metal deposits elsewhere in the world. The authors hold that they were formed during the Indian-Asian continental collision and developed within the foldthrust belt combined with thrust and strike-slip-related Cenozoic basins in the interior of the collisional zone. Studying on the metallogenic epochs of these two deposits is helpful to the understanding of ore-forming regularity of the regional Pb-Zn-Cu mineralization belt and also to the search for new deposits in this region. The age of the Dongmozhazhua deposit has been determined by the Rb-Sr isochron method for sphalerite residues, whereas the age of the Mohailaheng deposit has been determined by the Rb-Sr isochron method for sphalerite residues and the Sm-Nd isochron method for fluorite. The age of the Dongmozhazhua deposit is 35.0±0.0 Ma((87Sr/86Sr)0=0.708807) for sphalerite residues. The age of the Mohailaheng deposit is 32.2±0.4 Ma((87Sr/86Sr)0=0.708514) for sphalerite residues and 31.8±0.3 Ma((143Nd/144Nd)0=0.512362) for fluorite with an average of 32.0 Ma. Together with the regional geological setting during mineralization, a possible tectonic model for metallogeny of the Dongmozhazhua and Mohailaheng Pb-Zn deposits has been established. These two ages are close to the ages of the Pb-Zn deposits in the Lanping and Tuotuohe basins, indicating that it is possible that the narrow 1000-kilometer-long belt controlled by a thrust nappe system on the eastern and northern margins of the Tibetan plateau could be a giant Pb-Zn mineralized belt. | TIAN Shihong GONG Yingli YANG Zhusen HOU Zengqian LIU Yingchao SONG Yucai XUE Wanwen LU Haifeng WANG Fuchun ZHANG Yubao ZHU Tian YU Changjie | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 8 |
| 2 | Spatial distribution of polychlorinated biphenyls in soil around a municipal solid waste incinerator显示文摘The impact of a typical municipal solid waste incinerator (MSWI) on polychlorinated biphenyl (PCB) concentrations in the surrounding soil was studied. Six stack gas samples were taken from the MSWI and 21 soil samples were collected from sampling sites between 300 and 1700 m from the MSWI stack. The total (∑PCB) concentrations of dioxin-like (dl) PCBs and indicator PCBs in the stack gas samples were between 3.41 and 34.3 ng/m3, and the corresponding toxic equivalents (TEQs) ranged from 4.45 to 66.9 pg WHO-TEQ/m3, with a mean of 28.6 pg WHO-TEQ/m3. A total of 2.43 g WHO-TEQ of PCBs per year was calculated to be released into the environment from MSWIs in China. The ∑PCB concentrations in the soil samples ranged from 28.0 to 264.4 pg/g, with mean and median values of 127.6 and 127.7 pg/g, respectively, while the TEQ values were between 0.020 and 0.18 pg WHO-TEQ/g, with mean and median values of 0.074 and 0.062 pg WHO-TEQ/g, respectively. Comparing this study with other studies performed around the world suggest that PCB emission from incinerators has a critical influence on PCB concentrations in the surrounding soil. An exponential function equation is proposed, which indicates a clear decline in ∑PCB concentrations with increasing distance from the stack. A contour map created using an ordinary kriging interpolation technique showed that a limited area (1250 m radius) from the stack was clearly influenced by PCB emission from the MSWI. | Wenbin Liu Haifeng Li Zhenyu Tian Huiting Xie Jicheng Hu | 2013 | Journal of Environmental Sciences2013，25，8： | 5 |
| 3 | Structural shifts in the intestinal microbiota of rats treated with cyclosporine A after orthotropic liver transplantation显示文摘Understanding the effect of immunosuppressive agents on intestinal microbiota is important to reduce the mortality and morbidity from orthotopic liver transplantation (OLT). We investigated the relationship between the commonly used immunosuppressive agent cyclosporine A (CSA) and the intestinal microbial variation in an OLT model. The rat samples were divided as follows:(1) N group (normal control);(2) I group (isograft LT, Brown Norway [BN] rat to BN);(3) R group (allograft LT, Lewis to BN rat);and (4) CSA group (R group treated with CSA). The intestinal microbiota was assayed by denaturing gradient gel electrophoresis profiles and by using real-time polymerase chain reaction. The liver histopathology and the alanine/aspartate aminotransferase ratio after LT were both ameliorated by CSA. In the CSA group, the numbers of rDNA gene copies of Clostridium cluster I, Clostridium cluster XIV, and Enterobacteriaceae decreased, whereas those of Faecalibacterium prausnitzii increased compared with the R group. Cluster analysis indicated that the samples from the N, I, and CSA groups were clustered, whereas the other clusters contained the samples from the R group. Hence, CSA ameliorates hepatic graft injury and partially restores gut microbiota following LT, and these may benefit hepatic graft rejection. | Junjun Jia Xinyao Tian Jianwen Jiang Zhigang Ren Haifeng Lu Ning He Haiyang Xie Lin Zhou Shusen Zheng | 2019 | Frontiers of Medicine2019，13，4： | 5 |
| 4 | Brain dopaminergic system changes in drug addiction:a review of positron emission tomography findings显示文摘Dopamine(DA)is considered crucial for the rewarding effects of drugs of abuse,but its role in addiction remains unclear.Positron emission tomography(PET)is the first technology used for in vivo measurement of components of the dopaminergic system in the human brain.In this article,we review the major findings from PET imaging studies on the involvement of DA in drug addiction,including presynaptic DA synthesis,vesicular monoamine transporter 2,the DA transporter,and postsynaptic DA receptors.These results have corroborated the role of DA in addiction and increased the understanding of its underlying mechanisms. | Haifeng Hou Chunyan Wang Shaowei Jia Shu Hu Mei Tian | 2014 | Neuroscience Bulletin2014，30，5： | 3 |
| 5 | Extending the EMMS/bubbling model to fluidization of binary particle mixture: Formulation and steady-state validation显示文摘The EMMS/bubbling model originally proposed for fluidization of monodisperse particles is extended to fluidization of binary particle mixture in this study.The dense and dilute phases are considered to comprise of two types of particles differing in size and/or density.Governing equations and the stability condition are then formulated and solved by using an optimization numerical scheme.The effects of bubble diameter are first investigated and a suitable bubble diameter correlation is chosen.Preliminary validation for steady state behavior shows the extended model can fairly capture the overall hydrodynamic behaviors in terms of volume fraction of bubbles and average bed voidage for both monodisperse and binary particle systems.This encourages us to integrate this model with CFD for more validations in the future. | Nouman Ahmad Yujie Tian Bona Lu Kun Hong Haifeng Wang Wei Wang | 2019 | Chinese Journal of Chemical Engineering2019，27，1： | 2 |
| 6 | Catalytic performance of imidazole modified HZSM-5 for methanol to aromatics reaction显示文摘A facile approach was developed for the preparation of nano-sized HZSM-5 with a hierarchical mesoporous structure by adding imidazole into conventional zeolite synthesis precursor solution. The physicochemical properties of modified HZSM-5 were characterized by X-ray diffraction(XRD), N_2 adsorption–desorption isotherms, scanning electron microscopy(SEM), NH_3-temperature-programmed desorption(NH_3-TPD) and pyridine adsorption infrared spectroscopy(Py-IR). The coke in spent catalysts was characterized by thermogravimetry(TG). The results showed that hierarchical HZSM-5 zeolites with excellent textural properties, such as abundant porous structure, uniform particle size and suitable acidity, could be synthesized by the recipe of one-pot synthesis routes. Moreover, the obtained HZSM-5 exhibited higher selectivity of total aromatics as well as longer lifetime in the catalytic conversion of methanol to aromatics, comparing with conventional HZSM-5. It is expected that the synthesis approach demonstrated here will be applicable to other zeolites with particular textural properties and controllable particle sizes, facilitating the emergence of new-type porous materials and their related applications in catalysis and separation. | Haifeng Tian Zhuangzhuang Zhang Hui Chang Xiaoxun Ma | 2017 | Journal of Energy Chemistry2017，26，3： | 2 |
| 7 | Two-dimensional characterization of three-dimensional magnetic bubbles in Fe_(3)Sn_(2) nanostructures显示文摘We report differential phase contrast scanning transmission electron microscopy(TEM) of nanoscale magnetic objects in Kagome ferromagnet Fe_(3)Sn_(2) nanostructures. This technique can directly detect the deflection angle of a focused electron beam, thus allowing clear identification of the real magnetic structures of two magnetic objects including three-ring and complex arch-shaped vortices in Fe_(3)Sn_(2) by Lorentz-TEM imaging. Numerical calculations based on real material-specific parameters well reproduced the experimental results, showing that the magnetic objects can be attributed to integral magnetizations of two types of complex three-dimensional(3D) magnetic bubbles with depth-modulated spin twisting. Magnetic configurations obtained using the high-resolution TEM are generally considered as two-dimensional(2D)magnetic objects previously. Our results imply the importance of the integral magnetizations of underestimated 3D magnetic structures in 2D TEM magnetic characterizations. | Jin Tang Yaodong Wu Lingyao Kong Weiwei Wang Yutao Chen Yihao Wang Y.Soh Yimin Xiong Mingliang Tian Haifeng Du | 2021 | National Science Review2021，8，6： | 2 |
| 8 | Propagation Characteristics of Elevation Angles and Three Dimensional Fading Channel Model with Angle Offset显示文摘Three dimensional(3D)Multiple Input and Multiple Output(MIMO)is one of the most promising techniques for the 5th generation(5G)mobile communication system.To support its research,the property of elevation angle in 3D channel model should be accurately modeled.Conventionally,3D channel is modeled with an assumption that the mean elevation angle of multipaths is coincided with the line-of-sight(LOS)direction.In order to investigate its authenticity and give the reliable 3D channel model,extensive 3D multiple antenna field channel measurements with 100 MHz bandwidth are conducted in three typical scenarios,including outdoor to indoor(O2I),urban microcell(UMi)and urban macrocell(UMa).The statistical characteristics and parameters are extracted and analyzed based on the measurement data.It is found that the assumption holds in the LOS condition.However,for non-line-of-sight(NLOS)condition,a difference exists between the mean elevation angle and the direction connecting transmitter and receiver,which is defined as the elevation angle offset.Then,the eigenvalue distribution and capacity are compared between the reconstructed 3D channels with and without elevation angle offset.Results show that the performance of 3D channel with angle offset fits the measurement data better whereas that without angle offset is underestimated. | Lei Tian Jianhua Zhang Haifeng Tan Pan Tang Guangyi Liu | 2019 | China Communications2019，16，9： | 2 |
| 9 | Homeobox B8 Targets Sterile Alpha Motif Domain-Containing Protein 9 and Drives Glioma Progression显示文摘Gliomas are the most commonly occurring tumors of the central nervous system. Glioblastoma multiforme (GBM) is the most malignant and aggressive brain cancer in adults. Further understanding of the mechanisms underlying the aggressive nature of GBM is urgently needed. Here we identified homeobox B8(HOXB8), a member of the homeobox family, as a crucial contributor to the aggressiveness of GBM. Data mining of publicly accessible RNA sequence datasets and our patient cohorts confirmed a higher expression of HOXB8 in the tumor tissue of GBM patients, and a strong positive correlation between the expression level and pathological grading of tumors and a negative correlation between the expression level and the overall survival rate. We next showed that HOXB8 promotes the proliferation and migration of glioblastoma cells and is crucial for the activation of the PI3K/AKT pathway and expression of epithelial–mesenchymal transition-related genes, possibly through direct binding to the promoter of SAMD9 (Sterile Alpha Motif Domain-Containing Protein 9) and activating its transcription. Collectively, we identified HOXB8 as a critical contributor to the aggressiveness of GBM, which provides insights into a potential therapeutic target for GBM and opens new avenues for improving its treatment outcome. | Wenping Ma Hongze Jin Wenjie Liu Xiaojuan Li Xingang Zhou Xinwu Guo Runfa Tian Qi Cui Junjie Luo Yueying Jiao Youtao Yu Haifeng Yang Hongshan Zhao | 2020 | Neuroscience Bulletin2020，36，4： | 2 |
| 10 | Polychlorinated dibenzo-p-dioxins and dibenzofurans and polychlorinated biphenyls in surface soil from the Tibetan Plateau显示文摘Concentrations of Polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs) and polychlorinated biphenyls(PCBs) in soil samples from Tibetan Plateau were determined. The average concentration of total 2,3,7,8-PCDD/Fs was(2.30 ± 1.02) pg/g, and World Health Organization Toxicity Equivalency(WHO-TEQ) average concentration was(0.013 ± 0.010)pg WHO-TEQ/g. The average concentration of ∑PCBs(7 indicator PCB and 12 dioxin like-PCB congeners) was(16.2 ± 9.25) pg/g, and WHO-TEQ average concentration was 0.043 ±0.049 pg WHO-TEQ/g. Comparing to previous studies in similar environmental conditions,PCDD/Fs and PCBs in this study showed a relatively lower concentration. The altitude dependences of PCDD/Fs and PCBs were also studied. Total organic carbon(TOC) normalized concentrations presented a quadratic relation with the altitudes, and an inflection could be found on the parabola of the total concentrations and some congeners of high concentration.The concentrations decreased with altitudes below about 4500 m above sea level(a.s.l.), while they increased with altitudes above it. These phenomena indicate that cold condensation of PCDD/Fs and PCBs would happen above 4500 m a.s.l, on the Tibetan Plateau. | Zhenyu Tian Haifeng Li Huiting Xie Chen Tang Ying Han Mengjing Wang Wenbin Liu | 2014 | Journal of Environmental Sciences2014，26，10： | 2 |
| 11 | Incorporation of layered tin(Ⅳ) phosphate in graphene framework for high performance lithium-sulfur batteries显示文摘To anchor the polysulfide and enhance the conversion kinetics of polysulfide to disulfide/sulfide is critical for improving the performance of lithium-sulfur battery.For this purpose,the graphene-supported tin(Ⅳ) phosphate(Sn(HPO_4)_2·H_2 O,SnP) composites(SnP-G) are employed as the novel sulfur hosts in this work.When compared to the graphene-sulfur and carbon-sulfur composites,the SnP-G-sulfur composites exhibit much better cycling performance at 1.0 C over 800 cycles.Meanwhile,the pouch cell fabricated with the SnP-G-sulfur cathodes also exhibits excellent performance with an initial capacity of1266.6 mAh g^(-1)(S) and capacity retention of 76.9% after 100 cycles at 0.1 C.The adsorption tests,density functional theory(DFT) calculations in combination with physical cha racterizations and electrochemical measurements provide insights into the mechanism of capture-accelerated conversion mechanism of polysulfide at the surface of SnP.DFT calculations indicate that the Li-O bond formed between Li atom(from Li_2 S_n,n=1,2,4,6,8) and O atom(from PO_3-OH in SnP) is the main reason for the strong interactions between Li_2 S_n and SnP.As a result,SnP can effectively restrain the shuttle effect and improving the cycling performance of Li-S cell.In addition,by employing the climbing-image nudged elastic band(ciNEB) methods,the energy barrier for lithium sulfide decomposition(charging reaction) on SnP is proved to decrease significantly compared to that on graphene.It can be concluded that SnP is an effective sulfur hosts acting as dual-functional accelerators for the conversion reactions of polysulfude to sulfide(discharging reaction) as well as polysulfide to sulfur(charging reaction). | Haifeng Yuan Na Zhang Leiwu Tian Lei Xu Qinjun Shao Syed Danish Ali Zaidi Jianping Xiao Jian Chen | 2021 | Journal of Energy Chemistry2021，30，2： | 2 |

| 15 | The weeping characteristic of submerged multi-orifice plate显示文摘Weeping is an adverse phenomenon which results in higher pressure drop and poorer aeration performance.Visual experiments have been conducted to study the mechanism by which weeping impairs the work performance of multi-orifice plate.A theoretical model is improved to analyze the weeping phenomenon of multiorifice plate based on potential flow theory.The relations of different bubbling conditions and weeping rate are analyzed.Weeping condition and average weeping rate have relation with the driven pressure differential and dynamic variation of gas chamber pressure.In addition,a set of experiments are designed to study the influence of various factors on weeping rate.The bubble coalescence during bubble formation is a fatal factor determining weeping rate,so the relation between weeping rate and gas flow rate is concerned with the pitch of orifices and orifice diameter.There is a critical plate thickness which is in favor of weeping. | Jiming Wen Ruifeng Tian Sichao Tan Qiunan Sun Haifeng Gu | 2020 | Chinese Journal of Chemical Engineering2020，28，4： | 1 |

| 17 | Ultra-broadband,fast,and polarization-sensitive photoresponse of low-symmetry 2D NdSb_(2)显示文摘Broadband photodetectors with polarization-sensitive ability have received extraordinary attention for modern optoelectronic devices.Ideal photodetectors should possess high responsivity,fast response,and good stability,which are rare to meet at the same time in one low-symmetric two-dimentional(2D)material.In this work,neodymium diantimonides(RSb_(2)),a member of light rare-earth diantimonides RSb_(2)(R=La–Nd,Sm)with low-symmetry structure,is introduced as a fascinating highly anisotropic 2D material for broadband detection(532 nm to 4μm).The photodetector exhibits a responsivity of 0.49 mA·W^(−1)with 15μs response time at 532 nm and highly stable performance under ambient conditions over 8 months.Furthermore,we identify the polarization-sensitive photoresponse of the detector and demonstrate a high anisotropic factor~1.6.In addition,strong inplane anisotropy is revealed by anisotropic phonon response and the photodetection mechanism is investigated by scanning photocurrent microscopy measurements.This pioneer work on RSb_(2)paves the way for further exploration of 2D RSb_(2)for high performance polarized photodetectors with fast photothermoelectric response. | Gang Li Hanlin Zhang Yong Li Shiqi Yin Xucai Kan Wensen Wei Haifeng Du Binghui Ge Chao An Mingliang Tian Feng Yan Sanjun Yang Tianyou Zhai Liang Li | 2022 | Nano Research2022，15，6： | 1 |
| 18 | Effects of Al^3+ on the microstructure and bioflocculation of anoxic sludge显示文摘The aluminum ions generated from mining aluminum,electrolytic aluminum and the industrial production of aluminum-based coagulants(such as AlCl3 and Al2(SO4)3)enter sewage treatment plants and interact with activated sludges.An anaerobic/anoxic/oxic(A2^O)process was used to reveal the effects of Al^3+on the pollutant removal efficiencies,bioflocculation and the micro structure of sludge.The results showed that a low concentration of Al^3+improved the pollutant removal efficiencies and increased the sludge particle size.However,a high concentration of Al^3+hindered microbial flocculation and reduced the pollutant removal efficiencies.With a 10 mg/L Al^3+addition,the chemical oxygen demand(COD),total nitrogen(TN)and NH4+-N increased by 3%,16%and 27%,and reached as high as 68%,60%and 87%,respectively.At the same time,the dehydrogenase activity,flocculation ability(FA)and contact angle of the sludge reached their maximum levels at 41.3 mg/L/hr,45%and 79.63°,respectively.The specific surface area of the sludge decreased to 7.084 m2/g and the sludge pore size distribution shifted to concentrate in the me soporous range.Most of Al^3+was adsorbed on the surface of sludge,changing the physicochemical properties and physical structure of the sludge. | Lanhe Zhang Jing Zheng Shulei Tian Haifeng Zhang Xiaohui Guan Suiyi Zhu Xiaoyu Zhang Yuxuan Bai Ping Xu Jian Zhang Zheng Li | 2020 | Journal of Environmental Sciences2020，32，5： | 1 |
