| 1 | Adsorption and Desorption Behavior of Tannic Acid in Aqueous Solution on Polyaniline Adsorbent显示文摘Tannic acid is generally considered as one of polyphenolic pollutants, which may cause severe threats to the environment. In this study, polyaniline adsorbent was synthesized by chemical oxidation to remove tannic acid in aqueous solutions. The adsorption amount of tannic acid varied greatly with pH of solution and strong adsorption was at pH 5.8-6.7. Coexisting cations, such as Na+, K+, and Ca2+, can enhance the adsorption of tannic acid on poly-aniline, which may be contributed to the electrostatic interaction between tannic acid and polyaniline. The adsorp-tion process could be well described by Langmuir model and the maximum adsorption capacity was 117.65 mg·g-1 at 35 ℃ and pH 6.0. The thermodynamic parameters calculated from the adsorption isotherms indicate that the ad-sorption of tannic acid is spontaneous and endothermic process. The polyaniline saturated with tannic acid can be desorbed in alkaline solution and regenerated adsorbent can be used repeatedly with high adsorption capacity, which implies that polyaniline adsorbents have a great potential in water purification for the removal of tannic acid. | WANG Jiahong JI Yan fen DING Shaolan MA Hongrui HAN Xiaojing | 2013 | Chinese Journal of Chemical Engineering2013，21，6： | 7 |
| 2 | Zircon U-Pb Age and Geochemistry of the Ore-hosting Ultramafic Complex of Zhou'an PGE-Cu-Ni Deposit,Henan Province,Central China显示文摘The Zhou'an PGE-Cu-Ni deposit was recently discovered in the Qinling orogenic belt bound by the Yangtze and the North China Cratons. It is a blind deposit thoroughly covered by the Cenozoic alluvial sediments in the Nanyang Basin. As the first large PGE-Cu-Ni deposit discovered in the Qinling-Dabie-Sulu orogenic belt, its geological and geochemical characteristic, isotope age, genesis and tectonic setting are of wide concern in both scientific studies and ore exploration. In this contribution, we report the results obtained from a pioneering study. The Zhou'an ultramafic complex is ferruginous, with m/f=4.79-5.08, and shows the nature of tholeiite series. It is rich in light rare earth elements, Rb, Th, U, La, Sm, Zr and Hf, and poor in heavy rare earth elements, Nd and Ta, suggesting an intraplate setting. It has high 87Sr/86Sr and low 143Nd/144Nd ratios. The ratios of Zr/Nb, La/Nb, Ba/Nb, Rb/Nb, Th/Nb, Th/La and Ba/La, suggest the magma originated from lithosphere mantle. The Fo values of olivine and Pd/Ir-Ni/Cu diagram suggest primary magma was High Mg basalt. The laser ablation inductively coupled plasma atomic emission spectroscopy zircon U-Pb age is 641.5±3.7 Ma. | YAN Haiqing DING Ruiying TANG Zhongli WANG Yalei LIU Shuang MA Jiahong HU Yanqiang CHEN Kena | 2012 | Acta Geologica Sinica(English Edition)2012，86，6： | 6 |

| 12 | Construction of High Dependable Distributed Access Control Architecture Based on Quorum System显示文摘Quorum system is a preferable model to construct distributed access control architecture, but not all quorum system can satisfy the requirements of distributed access control architecture. Aiming at the dependable problem of authorization server in distributed system and combining the requirements of access control, a set of criterions to select and evaluate quorum system is presented. The scheme and algorithm of constructing an authorization server system based on Paths quorum system are designed, and the integrated system performance under some servers attacked is fully analyzed. Role-based access control on the Web implemented by this scheme is introduced. Analysis shows that with certain node failure probability, the scheme not only has high dependability but also can satisfy the special requirements of distributed access control such as real-time, parallelism, and consistency of security policy. | XIONG Tinggang LU Zhengding ZHANG Jiahong MA Zhong | 2010 | Wuhan University Journal of Natural Sciences2010，15，3： | 1 |
| 13 | The Regulating Effect of CCK and Gastrin on Apoptosis of Bile Duct Carcinoma Cells显示文摘Objective:Probe into the influence and the mechanisms of CCK and gastrin on the apoptosis of bile duct carcinoma cells. Methods:By taking beauvericin as the revulsant to the apoptosis of bile duct carcinoma cells, the influence of CCK and gastrin on the apoptosis of bile duct carcinoma cells was investigated by using the teehniques such as TUNEL fluorescent staining, stream mode cell detecting instrument and reverse bcl-2 oligonucleotide. Techifiques of immunohistochemistry, in situ hybridization,flow cytometry(FCM),RT-PCR were used to study the roles of apoptosis-related genes bcl-2 and bax Results:After beauvericin 40 μM worked for 12 h, the survival rate of QBC939 bile duct carcinoma cells was decreased by 35%-40%.About 80% of the bile duct carcinoma cells showed various degrees of apoptosis.CCK and gastrin could upregulate the threshold value of the apoptosis of bile duct carcinoma cells, which could be inhibited by L60,L18 and reverse bcl-2 oligonucleotide. In terms of both transcription and translating levels,CCK and gastrin could obviously promote the genetic expression of bel-2,but had no influence on the genetic expression of bax. Addition of CCK-A receptor or CCK-B/gastr in receptor antagonist could remarkably inhibit the expression of bel-2 boosted by gastrin-17 and CCK-8S. Conclusion:CCK and gastrin inhibited the apoptosis of bile duct carcinoma cells through upregulating the genetic expression of bcl-2.Theoretically, this research has expanded our understanding to the mechanism of CCK and gastrin in controlling the growth of tumors, enriched our view to the mechanism of apoptosis of alimentary tract tumors, and has provided a new thinking for the assistant treatment to bile duct carcinoma cells as well. | MA Kuansheng, ZHANG Fengshen, HE Zhenping, DONG Jiahong The Institute of Hepatobiliary Surgery of PLA, Southwest Hospital, Third Military Medical University, Chongqing 400038, China | 2002 | The Chinese-German Journal of Clinical Oncology2002，1，1： | 0 |
| 14 | Application of the Double-difference Relocation Method Combined with Waveform Cross-correlation on the Three Gorges Reservoir Seismicity显示文摘In this paper,we use the double difference location method based on waveform crosscorrelation algorithm for precise positioning of the Three Gorges Reservoir( TGR)earthquakes and analysis of seismic activity. First,we use the bi-spectrum cross-correlation method to analyze the seismic waveform data of TGR encrypted networks from March,2009 to December,2010,and evaluate the quality of waveform cross-correlation analysis.Combined with the waveform cross-correlation of data obtained, we use the double difference method to relocate the earthquake position. The results show that location precision using bi-spectrum verified waveform cross-correlation data is higher than that by using other types of data,and the mean 2 sig-error in EW,NS and UD are 3.2 m,3.9 m and 6.2 m,respectively. For the relocation of the Three Gorges Reservoir earthquakes,the results show that the micro-earthquakes along the Shenlongxi river in the Badong reservoir area obviously show the characteristics of three linear zones with nearly east-west direction,which is in accordance with the small faults and carbonate strata line of the neotectonic period,revealing the reservoir water main along the underground rivers or caves permeated and induced seismic activity. The stronger earthquakes may have resulted from small earthquakes through the active layers. | Luo Jiahong Ma Wentao Li Chunzheng | 2017 | Earthquake Research in China2017，31，3： | 0 |
| 15 | The olfactory route is a potential way for SARS-CoV-2 to invade the central nervous system of rhesus monkeys显示文摘Neurological manifestations are frequently reported in the COVID-19 patients.Neuromechanism of SARS-CoV-2 remains to be elucidated.In this study,we explored the mechanisms of SARS-CoV-2 neurotropism via our established non-human primate model of COVID-19.In rhesus monkey,SARS-CoV-2 invades the CNS primarily via the olfactory bulb.Thereafter,viruses rapidly spread to functional areas of the central nervous system,such as hippocampus,thalamus,and medulla oblongata.The infection of SARS-CoV-2 induces the inflammation possibly by targeting neurons,microglia,and astrocytes in the CNS.Consistently,SARS-CoV-2 infects neuro-derived SK-N-SH,glial-derived U251,and brain microvascular endothelial cells in vitro.To our knowledge,this is the first experimental evidence of SARS-CoV-2 neuroinvasion in the NHP model,which provides important insights into the CNS-related pathogenesis of SARS-CoV-2. | Li Jiao Yun Yang Wenhai Yu Yuan Zhao Haiting Long Jiahong Gao Kaiyun Ding Chunxia Ma Jingmei Li Siwen Zhao Haixuan Wang Haiyan Li Mengli Yang Jingwen Xu Junbin Wang Jing Yang Dexuan Kuang Fangyu Luo Xingli Qian Longjiang Xu Bin Yin Wei Liu Hongqi Liu Shuaiyao Lu Xiaozhong Peng | 2021 | Signal Transduction and Targeted Therapy2021，6，5： | 0 |
| 16 | Current Progress and Future Perspectives of Electrolytes for Rechargeable Aluminum-Ion Batteries显示文摘Aluminum-ion batteries(AIBs)with Al metal anode are attracting increasing research interest on account of their high safety,low cost,large volumetric energy density(≈8046 mA h cm−3),and environmental friendliness.Specifically,the reversible Al electrostripping/deposition is achieved with the rapid development of room temperature ionic liquids,and rapid progress has been made in fabricating high-performance and durable AIBs during the past decade.This review provides an integrated comprehension of the evolution of AIBs and highlights the development of various non-aqueous and aqueous electrolytes including high-temperature molten salts,room temperature ionic liquids,and gel–polymer electrolytes.The critical issues on the interplay of electrolytes are outlined in terms of the voltage window span,the effective ion species during charge storage(Al 3+or Al x Cl?y)and their underlying charge transfer(e.g.,interfacial transfer and diffusion),and the solid electrolyte interface formation and its role.Following the critical insight,future perspectives on how to practically design feasible AIBs are given. | Dongwei Ma Du Yuan Carlos Ponce de Leon Zheng Jiang Xin Xia Jiahong Pan | 2023 | Energy & Environmental Materials2023，6，1： | 0 |
| 17 | Acoustic spin-1 Weyl semimetal显示文摘The study of topological semimetals hosting spin-1 Weyl points(WPs)beyond Dirac points and WPs has attracted a great deal of attention.However,a spin-1 Weyl semimetal that exclusively possesses spin-1 WPs in a clean frequency window without being shadowed by any other nodal points is yet to be discovered.This study reports a spin-1 Weyl semimetal in a phononic crystal.Its spin-1 WPs are touched by two linear dispersions and an additional flat band and carry monopole charges(-2,0,2)or(2,0,-2)for the three bands from the bottom to the top.They result in double Fermi arcs,which occur between the first and second bands,as well as between the second and third bands.Further robust propagation is observed against the multiple joints and topological negative refraction of the acoustic surface arc wave.The results of this study create the basis for the exploration of the unusual properties of spin-1 Weyl physics on a macroscopic scale. | WeiYin Deng XueQin Huang JiuYang Lu Feng Li JiaHong Ma ShuQi Chen ZhengYou Liu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，8： | 0 |
