2Teleportation of an arbitrary two-qudit state based on the non-maximally four-qudit cluster state显示文摘Two different schemes are presented for quantum teleportation of an arbitrary two-qudit state using a non-maximally four-qudit cluster state as the quantum channel. The first scheme is based on the Bell-basis measurements and the re-ceiver may probabilistically reconstruct the original state by performing proper transformation on her particles and an auxiliary two-level particle; the second scheme is based on the generalized Bell-basis measurements and the probability of successfully teleporting the unknown state depends on those measurements which are adjusted by Alice. A comparison of the two schemes shows that the latter has a smaller probability than that of the former and contrary to the former, the channel information and auxiliary qubit are not necessary for the receiver in the latter.TIAN DongPing TAO YingJuan QIN Meng 2008Science China(Physics,Mechanics & Astronomy)2008,51,10:14
3Research and Development of Supercritical Carbon Dioxide Coal-Fired Power Systems显示文摘Using supercritical carbon dioxide(S-CO2)Brayton cycle instead of the traditional steam Rankine cycle is a promising technique to enhance the coal-fired power generation efficiency.Researchers from all over the world are actively designing and exploring efficient S-CO2 coal-fired power plants in recent years with great efforts made to overcome the significant technical challenges in the cycle layouts of S-CO2 and its specific thermal integration with coal-fired heat resources.This paper provides a detailed review of the research progress on the coal-fired power generation using S-CO2 Brayton cycles.The basic knowledge of S-CO2 properties,the promising S-CO2 power cycles and the conceptual designs for S-CO2 coal-fired power plants are comprehensively summarized,with some key issues in the constructing process and the corresponding engineering solutions being emphatically discussed.Based on the current achievements,the overall technical and economic evaluations on the S-CO2 coal-fired power system are figured out.Furthermore,the specific integration applications of S-CO2 cycles with different coal firing devices and modes including pulverized coal combustion,circulating fluidized bed combustion,oxy-coal combustion,pressurized fluidized bed combustion,chemical looping combustion are discussed.Finally,the main challenges requiring further studies are highlighted.LI Zhaozhi LIU Xuejiao SHAO Yingjuan ZHONG Wenqi 2020Journal of Thermal Science2020,29,3:9
4Preparation of polypropylene/montmorillonite nanocomposites by intercalative polymerization:Effect of in situ polymer matrix functionalization on the stability of the nanocomposite structure显示文摘The copolymerization of propylene and 5-hexenyl-9-borabicyclo[3.3.1]nonane (5-hexenyl-9-BBN) has been conducted with an MgCl2/TiCl4 catalyst intercalated in an organically modified montmorillonite (OMMT) with triethylaluminum (AlEt3) cocatalyst and diphenyldimethoxysilane (DDS) external donor. This polymerization process simultaneously results in both the exfoliation of MMT layers to realize the preparation of polypropylene (PP)/MMT nanocomposites and the implantation of reactive borane groups in the formed PP matrix. The polymer-borne borane groups have been able to undergo an effi-cient hydrolysis process under very mild reaction conditions (40℃, 3 h, in THF), introducing hydroxy groups into PP without sacrificing the polymerization-formed nanocomposite structure (the exfoliation of MMT). The resultant hydroxyl-functionalized PP/MMT nanocomposites exhibit enhanced structural stability against processing compared with those based on unfunctionalized PP matrix.YANG KeFang HUANG YingJuan DONG JinYong 2007Chinese Science Bulletin2007,52,2:9
5Entanglement in spin-1 Heisenberg XY chain显示文摘We investigated the quantum entanglement in spin-1 Heisenberg XY chain for two-spin-qutrit and multi-particle systems. As a measure of the entanglement, the negativity of this state was analyzed as a function of the temperature and the magnetic field. We gave some numerical results and discussed them in detail. We found that the negativity increases monotonously with the coupling constants |J1| and |J2|, and it showed a symmetry with respect to the point of J1=0 and J2=0. In addition to the above features, there is evidence that the critical temperature is independent of the length of the chain.QIN Meng TAO YingJuan HU MingLiang TIAN DongPing 2008Science China(Physics,Mechanics & Astronomy)2008,51,7:6

7C0818,a novel curcumin derivative,interacts with Hsp90 and inhibits Hsp90 ATPase activity显示文摘The aims of the present study were to estimate the affinity between 3,5-(E)-bis(3-methoxy-4-hydroxybenzal)-4-piperidinone hydrochloride(C0818) and heat shock protein 90 (Hsp90) and to investigate the inhibitory effects of this compound on Hsp90 ATPase activity. Fluorescence spectroscopy was used to examine the affinity between varying concentrations of C0818 and Hsp90, N-Hsp90, MHsp90 and C-Hsp90. Fluorescence intensities were recorded in the range of 290–510 nm at 293, 303 and 310 K, respectively. A colorimetric assay for inorganic phosphate(based on the formation of a phosphomolybdate complex and the subsequent reaction with malachite green) were used to examine the inhibitory effects of C0818 on Hsp90 ATPase activity. The equilibrium dissociation constant K_D value of C0818 was found to be 23.41270.943 μmol/L. The interaction between C0818 and Hsp90 was driven mainly by electrostatic interactions. C0818 showed the strongest affinity with C-Hsp90. These results conclusively demonstrate the inhibitory activity of C0818 on the activity of Hsp90 ATPase.Yingjuan Fan Yang Liu Lianru Zhang Fang Cai Liping Zhu Jianhua Xu 2017Acta Pharmaceutica Sinica B2017,7,1:5
8Advanced Anode Materials of Potassium Ion Batteries:from Zero Dimension to Three Dimensions显示文摘Potassium ion batteries(PIBs)with the prominent advantages of sufficient reserves and economical cost are attractive candidates of new rechargeable batteries for large-grid electrochemical energy storage systems(EESs).However,there are still some obstacles like large size of K+to commercial PIBs applications.Therefore,rational structural design based on appropriate materials is essential to obtain practical PIBs anode with K+accommodated and fast diffused.Nanostructural design has been considered as one of the effective strategies to solve these issues owing to unique physicochemical properties.Accordingly,quite a few recent anode materials with different dimensions in PIBs have been reported,mainly involving in carbon materials,metal-based chalcogenides(MCs),metal-based oxides(MOs),and alloying materials.Among these anodes,nanostructural carbon materials with shorter ionic transfer path are beneficial for decreasing the resistances of transportation.Besides,MCs,MOs,and alloying materials with nanostructures can effectively alleviate their stress changes.Herein,these materials are classified into 0D,1D,2D,and 3D.Particularly,the relationship between different dimensional structures and the corresponding electrochemical performances has been outlined.Meanwhile,some strategies are proposed to deal with the current disadvantages.Hope that the readers are enlightened from this review to carry out further experiments better.Jiefeng Zheng Yuanji Wu Yingjuan Sun Jianhua Rong Hongyan Li Li Niu 2021Nano-Micro Letters2021,13,1:4
9Effects of different carbon sources on the removal of ciprofloxacin and pollutants by activated sludge:Mechanism and biodegradation显示文摘This research investigated the effects of ciprofloxacin(CIP)(0.5,5,and 20 mg/L)on SBR systems under different carbon source conditions.Microbial community abundance and structure were determined by quantitative PCR and high-throughput sequencing,respectively.The biodegradation production of CIP and possible degradation mechanism were also studied.Results showed that CIP had adverse effects on the nutrient removal from wastewater.Compared with sodium acetate,glucose could be more effectively used by microorganisms,thus eliminating the negative effects of CIP.Glucose stimulated the microbial abundance and increased the removal rate of CIP by 18%–24%.The mechanism research indicated that Proteobacteria and Acidobacteria had a high tolerance for CIP.With sodium acetate as a carbon source,the abundance of nitrite-oxidizing bacterial communities decreased under CIP,resulting in the accumulation of nitrite and nitrate.Rhodanobacter and Microbacterium played a major role in nitrification and denitrification when using sodium acetate and glucose as carbon sources.Dyella and Microbacterium played positive roles in the degradation process of CIP and eliminated the negative effect of CIP on SBR,which was consistent with the improved removal efficiency of pollutants.Yixiang Cai Zhiyong Yan Yingjuan Ou Boshang Peng Lihua Zhang Jihai Shao Yiqing Lin Jiachao Zhang 2022Journal of Environmental Sciences2022,34,1:4
10A novel superconducting magnetic levitation method to support the laser fusion capsule by using permanent magnets显示文摘A novel magnetic levitation support method is proposed, which can relieve the perturbation caused by traditional support methods andprovide more accurate position control of the capsule. This method can keep the perfect symmetry of the octahedral spherical hohlraum and hasthe characteristics in stability, tunability and simplicity. It is also favorable that all the results, such as supporting forces acting on the super-conducting capsule, are calculated analytically, and numerical simulations are performed to verify these results. A typical realistic design isproposed and discussed in detail. The superconducting coating material is suggested, and the required superconducting properties are listed.Damped oscillation of the floating capsule in thin helium gas is discussed, and the restoring time is estimated.Xiaojia Li Tingting Xiao Fengwei Chen Yingjuan Zhang Xiaofei Li Weidong Wu 2018Matter and Radiation at Extremes2018,3,3:4

12System Analysis on Supercritical CO_2 Power Cycle with Circulating Fluidized Bed Oxy-Coal Combustion显示文摘Supercritical carbon dioxide(S-CO_2) Brayton power cycle is a competitive technology to achieve high efficiency in a variety of applications. However, in coal power applications, the CO_2 generated from coal combustion still discharges into the atmosphere causing a series of environment problems. In this work, an 300 MWe S-CO_2 power cycle with circulating fluidized bed(CFB) oxy-coal combustion was established including air separation unit(ASU), CFB boiler, recuperator system and carbon dioxide compression and purification unit(CPU). Based on the material and energy conservation, the cycle efficiency of S-CO_2(620°C, 25 MPa) Brayton power cycle with CFB oxy-coal combustion is evaluated compared to the oxy-coal combustion steam Rankine cycle and S-CO_2 Brayton power cycle with the 31.65 kg/s coal supply. After that, the influence of several factors, e.g., exhaust flue gas temperature, split ratio in recuperator system and the oxygen supply on the cycle efficiency was investigated and analyzed. The results show that the net efficiency of S-CO_2 power cycle with CFB oxy-coal combustion(32.67%) is much higher than the steam Rankine cycle utilizing CFB with 17.5 Mpa, 540°C steam(27.3%), and 25 Mpa, 620°C steam(30.15%) under the same exhaust flue gas temperature. In addition, lower exhaust flue gas temperature and higher split ratio are preferred to achieve higher cycle efficiency. Lower oxygen supply can reduce the energy consumption of ASU and CPU, further increasing the system net efficiency. However, the energy losses of ASU and CPU are still very large in oxy-coal combustion and need to be improved in further work.SHI Yan ZHONG Wenqi SHAO Yingjuan XIANG Jun 2019Journal of Thermal Science2019,28,3:3
13Environmental exposure and flux of thallium by industrial activities utilizing thallium-bearing pyrite显示文摘Thallium(Tl) is a typical toxic heavy metal,with higher toxicity to mammals than Hg,Cd,and Pb.Accurate assessments of its environmental exposure and flux are central to effective management and control of Tl pollution.This paper first presents in detail the environmental exposure and flux of Tl by typical industrial activities utilizing Tl-bearing pyrite minerals to produce sulfuric acid.For this purpose,sequential extraction and Inductively Coupled Plasma Mass Spectrometry(ICP-MS) were used to investigate total content and geo-chemical partitioning of Tl in raw pyrite ores and solid roasting wastes,thereby uncovering Tl distribution and transformation during the production process.Results showed that some portions of Tl bearing in the minerals went into vapor,which transferred Tl into different processes;and some portions of Tl went into water during the gas washing procedure,leaving some other portions remained in the solid slags.More importantly,detailed investigation revealed that 40% of Tl in the pyrite minerals was active,among which 25% of Tl originally in the pyrite minerals was washed into water during gas cleaning process and 15% of active Tl retained in the slags.The latter portion of active Tl could be possibly transferred to the soil or water with the slag deposal or being reused;and 60% of Tl remained relatively stable in the residual phase.CHEN YongHeng WANG ChunLin LIU Juan WANG Jin QI JianYing WU YingJuan 2013Science China Earth Sciences2013,56,9:3
14Application of Lignin and Its Derivatives as Slow/Controlled Release Materials in Agricultural Fields显示文摘Lignin is the main by-product of pulp and papermaking and is not effectively utilized. Conversion of industrial lignins into value-added materials is beneficial for the effective utilization of resources as well as for environmental protection. Because of their adsorptivity, slow-release property,biocompatibility, and biodegradability, lignin and its derivatives find potential applications as eco-friendly slow/controlled release materials in agricultural fields. This report reviews the recent research advances in lignin-based slow/controlled release fertilizers and pesticides.YingJuan Fu MengHua Qin ZhaoJiang Wang ZongQuan Li 2018Paper And Biomaterials2018,3,1:3
15Study on the emission characteristics of nitrogen oxides with coal combustion in pressurized fluidized bed显示文摘Nitrogen oxides are one of the most significant pollution sources during coal combustion. This experimental study was conducted in a 15 kWth lab-scale pressurized fluidized bed (inner diameter = 81-100 mm, H = 2100 mm) firing with bituminous coals. The effects of operating parameters, including bed temperature (800℃-900℃), operating pressure (0.1-0.4 MPa), excess air level (16%-30%) and flow pattern on NOX and N2O emissions were systematically studied during the tests. During each test the interaction effects of all the operating parameters were properly controlled. The results show that most operating parameters have an opposite effect on NOX and N2O emissions, and the N2O emissions mainly depend on the bed temperature. Increasing the operating pressure can significantly suppress the fuel-N conversion to NOX but enhance its conversion to N2O. With the rise of the excess air level and fluidization number, NOX emissions grow distinctly while N2O emissions remain almost unchanged. Total nitrogen oxide emissions increase with the bed temperature while decrease with the operating pressure.Zheng Gong Yingjuan Shao Lei Pang Wenqi Zhong Chao Chen 2019Chinese Journal of Chemical Engineering2019,27,5:2
16Nanoporous MoO_(3−x)/BiVO_(4)photoanodes promoting charge separation for efficient photoelectrochemical water splitting显示文摘Owing to the relatively short hole diffusion length,severe charge recombination in the bulk of bismuth vanadate(BiVO_(4))is the key issue for photoelectrochemical water splitting.Herein,we design a nanoporous MoO_(3−x)/BiVO_(4)heterojunction photoanode to promote charge separation.The efficient electron transport properties of oxygen deficient MoO_(3−x)and the nanoporous structure are beneficial for charge separation,leading to a significantly enhanced PEC performance.The optimized MoO_(3−x)/BiVO_(4)heterojunction photoanode exhibits a photocurrent density of 5.07 mA·cm^(−2)for Na_(2)SO_(3)oxidation.By depositing FeOOH/NiOOH dual oxygen evolution cocatalysts to promote surface kinetics,a high photocurrent density of 4.81 mA·cm^(−2)can be achieved for PEC water splitting,exhibiting an excellent applied bias photon-to-current efficiency of 1.57%.Moreover,stable overall water splitting is achieved under consecutive light illumination for 10 h.We provide a proof of concept for the design of efficient BiVO_(4)-based heterojunction photoanodes for stable PEC water splitting.Songcan Wang Boyan Liu Xin Wang Yingjuan Zhang Wei Huang 2022Nano Research2022,15,8:2
17Separation and Anti-Hantaan Virus Activity of Extracts from Alternanthera philoxcroides in vitro and in vivo显示文摘A water-soluble substance was extracted from the Chi-nese herb, Alternanthera philoxcroides with hot water and alcohol. Aliquots of this initial extract were further fractionated by treat-ment with ether, ethyl acetate and alcohol respectively. The four extracts were assayed for anti-viral activity against three serum, Hantaan virus 114 (HV114),HV435 and A9 strains. Results show that the four extracts are capable of inhibiting Hantaan virus propagation, of which extract No.1 has the best efficiency. The three dosage of extract No.1, which are used upon three Hantaan virus serum IC50, are 153, 157, 154 μ?/mL. New-born mice were made to be infected with HV114 and then fed in vivo with extract No.1 on the 3rd, 10th and 14th days after being infected by the virus. The treatment continued for 8 days with a dosage of 2.5 g/kg. Result shows that survival rates of mice were 75%, 50% and 0, respectively. The median time to death (MTDs) of the three groups were 37, 30, 23 days.LIU Yingjuan YANG Zhanqiu DENG Haiying XIAO Hong QU Chunfeng 2007Wuhan University Journal of Natural Sciences2007,12,6:2
18Fabricating multi-porous carbon anode with remarkable initial coulombic efficiency and enhanced rate capability for sodium-ion batteries显示文摘Due to the abundant sodium reserves and high safety,sodium ion batteries(SIBs)are foreseen a promising future.While,hard carbon materials are very suitable for the anode of SIBs owing to their structure and cost advantages.However,the unsatisfactory initial coulombic efficiency(ICE)is one of the crucial blemishes of hard carbon materials and the slow sodium storage kinetics also hinders their wide application.Herein,with spherical nano SiO_(2)as pore-forming agent,gelatin and polytetrafluoroethylene as carbon sources,a multi-porous carbon(MPC)material can be easily obtained via a co-pyrolysis method,by which carbonization and template removal can be achieved synchronously without the assistance of strong acids or strong bases.As a result,the MPC anode exhibited remarkable ICE of 83%and a high rate capability(208 m Ah/g at 5 A/g)when used in sodium-ion half cells.Additionally,coupling with Na3V2(PO4)3as the cathode to assemble full cells,the as-fabricated MPC//NVP full cell delivered a good rate capability(146 m Ah/g at 5 A/g)as well,implying a good application prospect the MPC anode has.Yong Tong Yuanji Wu Zihao Liu Yongshi Yin Yingjuan Sun Hongyan Li 2023Chinese Chemical Letters2023,34,1:2
19High Capacity and Fast Kinetics of Potassium‑Ion Batteries Boosted by Nitrogen‑Doped Mesoporous Carbon Spheres显示文摘In view of rich potassium resources and their working potential,potassium-ion batteries(PIBs)are deemed as next generation rechargeable batteries.Owing to carbon materials with the preponderance of durability and economic price,they are widely employed in PIBs anode materials.Currently,porosity design and heteroatom doping as efficacious improvement strategies have been applied to the structural design of carbon materials to improve their electrochemical performances.Herein,nitrogen-doped mesoporous carbon spheres(MCS)are synthesized by a facile hard template method.The MCS demonstrate larger interlayer spacing in a short range,high specific surface area,abundant mesoporous structures and active sites,enhancing K-ion migration and diffusion.Furthermore,we screen out the pyrolysis temperature of 900°C and the pore diameter of 7 nm as optimized conditions for MCS to improve performances.In detail,the optimized MCS-7-900 electrode achieves high rate capacity(107.9 mAh g^(−1) at 5000 mA g^(−1))and stably brings about 3600 cycles at 1000 mA g^(−1).According to electrochemical kinetic analysis,the capacitive-controlled effects play dominant roles in total storage mechanism.Additionally,the full-cell equipped MCS-7-900 as anode is successfully constructed to evaluate the practicality of MCS.Jiefeng Zheng Yuanji Wu Yong Tong Xi Liu Yingjuan Sun Hongyan Li Li Niu 2021Nano-Micro Letters2021,13,11:2
20Dynamic optimization oriented modeling and nonlinear model predictive control of the wet limestone FGD system显示文摘Nonlinear model predictive control(NMPC)scheme is an effective method of multi-objective optimization control in complex industrial systems.In this paper,a NMPC scheme for the wet limestone flue gas desulphurization(WFGD)system is proposed which provides a more flexible framework of optimal control and decision-making compared with PID scheme.At first,a mathematical model of the FGD process is deduced which is suitable for NMPC structure.To equipoise the model’s accuracy and conciseness,the wet limestone FGD system is separated into several modules.Based on the conservation laws,a model with reasonable simplification is developed to describe dynamics of different modules for the purpose of controller design.Then,by addressing economic objectives directly into the NMPC scheme,the NMPC controller can minimize economic cost and track the set-point simultaneously.The accuracy of model is validated by the field data of a 1000 MW thermal power plant in Henan Province,China.The simulation results show that the NMPC strategy improves the economic performance and ensures the emission requirement at the same time.In the meantime,the control scheme satisfies the multiobjective control requirements under complex operation conditions(e.g.,boiler load fluctuation and set point variation).The mathematical model and NMPC structure provides the basic work for the future development of advanced optimized control algorithms in the wet limestone FGD systems.Lukuan Yang Wenqi Zhong Li Sun Xi Chen Yingjuan Shao 2020Chinese Journal of Chemical Engineering2020,28,3:2
