| 1 | Teleportation 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 | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，10： | 14 |
| 2 | Effects of key factors of rotary triboelectrostatic separator on efficiency of fly ash decarbonization显示文摘On the basis of understanding the principle of rotary triboelectrostatic separation, dynamic analysis of charged fly ash particles aimed at determining the key factors and separation experiments to improve decarbonization efficiency had been carried out Variables of electrode plate voltage and corrected wind speed are the key factors which affect the decarbonization efficiency on the separation of fly ash, The results of separation experiments show that:(1) With the plate voltage increasing, the efficiency of decarbonization continuously rises and in its selected range, the optimal voltage level is 45 KV;(2) The corrected wind speed can impact the efficiency of decarbonization significantly: with the speed increasing, the efficiency of decarbonization shows a trend of first decline, then increase and decrease again, and in its selected range, the optimal speed is 2.0 m/s. This study is of significance for the improvement of rotary triboelectrostatic separation performance and its decarbonization separation efficiency. | Tao Youjun Zhang Ling Tao Dongping Xian Yushuai Sun Qixiao | 2017 | International Journal of Mining Science and Technology2017，27，6： | 10 |
| 3 | An innovative flake graphite upgrading process based on HPGR,stirred grinding mill, and nanobubble column flotation显示文摘Physical upgrading of graphite is typically achieved with many stages of grinding and flotation to produce a concentrate with approximately 95% carbon grade.An innovative grinding and column flotation process has been developed for efficient graphite upgrading to substantially simplify the process flowsheet and reduce operating costs.In this process,a high-pressure grinding roller(HPGR) and a stirred mill were employed as primary comminution techniques and a nanobubble flotation column as a key separation process.The results obtained with a crystalline flake graphite sample with a carbon grade of 11.15% show that the novel process can produce a concentrate with 94.82% carbon grade and 97.89% recovery from an open circuit of one rougher and two cleaner flotation stages.Scanning electron microscope(SEM)microphotographs indicate that HPGR offers the advantage of more effective protection of graphite flakes during crushing.Grinding test results show that stirred mill could not only protect graphite flakes but also promote the efficient liberation of graphite.Compared with the traditional flotation process,nanobubble flotation can effectively recover ultrafine graphite.The new process possesses a number of important advantages over the traditional method,including substantially higher graphite recovery,greatly simplified process flowsheet,better protection of flake size,reduced reagent consumption and process costs,etc. | Fangyuan Ma Dongping Tao Youjun Tao Shuyong Liu | 2021 | International Journal of Mining Science and Technology2021，31，6： | 9 |
| 4 | Electrical properties of fly ash and its decarbonization by electrostatic separation显示文摘The basic principle of fly ash triboelectrification is analysed. The mineral electrical index and test method are introduced. The electric difference of different mineral composition of fly ash is discussed by analysis of chemical and mineral composition of fly ash in Xinwen power plant. The dielectric constant and charge–mass ratio of carbon and ash of fly ash are tested. Combined with the experimental study on rotary triboelectrostatic separation, the charged characteristic of fly ash particles with different size is gained. The results show that the dielectric constant of fly ash with different grain size decreased with the decrease of particle size, which lead to the poor electrical conductivity. Thus it can be seen that particle size plays a leading role in conductivity. The charge of carbon and ash with each size increased with the decreased of particle size; and the charge–mass ratio between carbon and ash with the same size larger with the decrease of size, which indicated that the finer particle size, the more favorable for triboelectrification separation. In the same conditions, the best decarburization effect is realized when the particle size ranges from 0.038 to 0.074 mm, whose decarbonization rate and efficiency index reached 38.93% and120.83% respectively. | Tao Youjun Ding Qingqing Deng Mingrui Tao Dongping Wang Xu Zhang Jie | 2015 | International Journal of Mining Science and Technology2015，25，4： | 8 |
| 5 | Entanglement 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 | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，7： | 6 |
| 6 | Single‑Atom Cobalt‑Based Electrochemical Biomimetic Uric Acid Sensor with Wide Linear Range and Ultralow Detection Limit显示文摘Uric acid(UA)detection is essential in diagnosis of arthritis,preeclampsia,renal disorder,and cardiovascular diseases,but it is very challenging to realize the required wide detection range and low detection limit.We present here a single-atom catalyst consisting of Co(Ⅱ)atoms coordinated by an average of 3.4 N atoms on an N-doped graphene matrix(A-Co-NG)to build an electrochemical biomimetic sensor for UA detection.The A-Co-NG sensor achieves a wide detection range over 0.4-41,950μM and an extremely low detection limit of 33.3±0.024 nM,which are much better than previously reported sensors based on various nanostructured materials.Besides,the A-Co-NG sensor also demonstrates its accurate serum diagnosis for UA for its practical application.Combination of experimental and theoretical calculation discovers that the catalytic process of the A-Co-NG toward UA starts from the oxidation of Co species to form a Co^3+-OH-UA*,followed by the generation of Co^3+-OH+^*UA_H,eventually leading to N-H bond dissociation for the formation of oxidized UA molecule and reduction of oxidized Co^3+to Co^2+for the regenerated A-Co-NG.This work provides a promising material to realize UA detection with wide detection range and low detection limit to meet the practical diagnosis requirements,and the proposed sensing mechanism sheds light on fundamental insights for guiding exploration of other biosensing processes. | Fang Xin Hu Tao Hu Shihong Chen Dongping Wang Qianghai Rao Yuhang Liu Fangyin Dai Chunxian Guo Hong Bin Yang Chang Ming Li | 2021 | Nano-Micro Letters2021，13，1： | 2 |
| 7 | Surface nanobubble characterization and its enhancement mechanisms for fine-particle flotation:A review显示文摘Froth flotation is often used for fine-particle separation,but its process efficiency rapidly decreases with decreasing particle size.The efficient separation of ultrafine particles(UFPs)has been a major challenge in the mineral processing field for many years.In recent years,the use of surface nanobubbles in the flotation process has been recognized as an effective approach for enhancing the recovery of UFPs.Compared with traditional macrobubbles,nanobubbles possess unique surface and bulk characteristics,and their effects on the UFP flotation behavior have been a topic of intensive research.This review article is focused on the studies on various unique characteristics of nanobubbles and their mechanisms of enhancing the UFP flotation.The purpose of this article is to summarize the major achievements on the two topics and pinpoint future research needs for a better understanding of the fundamentals of surface nanobubble flotation and developing more feasible and efficient processes for fine and UFPs. | Fangyuan Ma Patrick Zhang Dongping Tao | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，4： | 2 |

A notable feature of the model lie in its capability to predict the thermodynamic properties of solutes in the Zn-Pb-ln and Zn-Sn-Cd-Pb dilute solutions using only the binary infinite dilute activity coefficients, and the predicted values are in good agreement with the experimental data of the dilute solutions. | Dongping TAO Zhuo CHEN Dunfang LI Yifeng GAO Qianghua SHEN School of Materials and Metallurgical Engineering, Kunming University of Science and Technology, Kunming 650093, China | 2004 | Journal of Materials Science & Technology2004，20，3： | 2 |
| 9 | Predication of Component Activities in the Molten Aluminosilicate Slag CaO-Al_2O_3-SiO_2 by Molecular Interaction Volume Model显示文摘A novel thermodynamic model-the molecular interaction volume model(MIVM)which can be reduced to the Flory-Huggins equation of polymer solution was employed for the prediction of component activities in the ternary molten aluminosilicate slag CaO-Al_2O_3-SiO_2 at different temperatures.The results show that the predicted values of activity of CaO,Al_2O_3 and SiO_2 are in reasonably agreement with experimental data in some ranges of their concentrations which are about x_1<0.25 for CaO,x_2=0.05-0.55 for Al_2O_3 and x_3=0.03-0.85 for SiO_2.This further shows that MIVM requires only two binary parameters for each sub-binary system to predict activities of all components in a multicomponent solution and is the superior alternative in a molten slag. | Dongping TAO | 2008 | Journal of Materials Science & Technology2008，24，5： | 2 |

| 18 | A novel cationic collector for silicon removal from collophane using reverse flotation under acidic conditions显示文摘We analyzed a novel cationic collector using chemical plant byproducts,such as cetyltrimethylammonium bromide(CTAB)and dibutyl phthalate(DBP).Our aim is to establish a highly effective and economical process for the removal of quartz from collophane.A microflotation test with a 25 mg·L^(−1)collector at pH value of 6-10 demonstrates a considerable difference in the floatability of pure quartz and fluorapatite.Flotation tests for a collophane sample subjected to the first reverse flotation for magnesium removal demonstrates that a rough flotation process(using a 0.4 kg·t−1 new collector at pH=6)results in a collophane concentrate with 29.33wt%P_(2)O_(5)grade and 12.66wt%SiO2 at a 79.69wt%P_(2)O_(5)recovery,providing desirable results.Mechanism studies using Fourier transform infrared spectroscopy,zeta potential,and contact angle measurements show that the adsorption capacity of the new collector for quartz is higher than that for fluorapatite.The synergistic effect of DBP increases the difference in hydrophobicity between quartz and fluorapatite.The maximum defoaming rate of the novel cationic collector reaches 142.8 mL·min−1.This is considerably higher than that of a conventional cationic collector. | Zhongxian Wu Dongping Tao Youjun Tao Man Jiang Patrick Zhang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，6： | 1 |
