| 1 | Spontaneous caving and gob-side entry retaining of thin seam with large inclined angle显示文摘Based on the research method of combining simulation analysis with field testing by distinct element process UDEC, we have analyzed the roof deformation and failure laws and roadway support technology of gob-side entry retaining in a thin seam with a large inclined angle. The results show that during exploitation in seams with large inclined angle, rotational subsidence of the main roof under the gob area is small and can maintain balance, so there is no need to provide artificial permanent support resistance for the main roof near the upper side to control rotational subsidence. Obstructed by the dense scrap rail,waste rock from the immediate roof caving slides from the upper gob area to the lower area and fills it,which strikes a balance between the immediate roof under the goaf after it fractures into large pieces and filling waste rocks. | Zhang Yongqin Tang Jianxin Xiao Daqiang Sun Lele Zhang Weizhong | 2014 | International Journal of Mining Science and Technology2014，24，4： | 3 |
| 2 | Effects of ZnCl2/H2O/C2H5OH Treatment on the Filter Paper Performance显示文摘Bleached softwood kraft pulp (BSKP) fibers were pretreated in a 5 mol/L NaOH aqueous solution at 35℃ for 90 min. The ZnCl2/H2O/ C2H5OH was used to treat the pretreated BSKP fibers, filter papers were then prepared. In the course of processing, the effects of various molar ratios of ZnCl2/H2O/C2H5OH on the filter paper performance were evaluated. SEMEDX was conducted to analyze the physical configuration of the filter papers. Moreover, FT-IR and XPS were performed to further characterize the BSKP, the pretreated BSKP and the filter paper fibers. The results indicated that the fibers treated by ZnCl2/H2O/C2H5OH were swollen and exhibited slight fibrillation, leading to a looser fiber structure and therefore, enhanced filter paper performance. Air permeability increased from 161.7 L/(m2·s) to 1450.4 L/(m2·s) for the filter papers when the molar ratio of ZnCl2/H2O/C2H5OH was 1:14:1. The optimum molar ratio of ZnCl2/H2O/C2H5OH was found to be 1:14:1, and no significant effect of ZnCl2/H2O/C2H5OH on fibers’ functional groups was detected. These results showed that filtration performance of filter papers was improved when treated with the ZnCl2/H2O/C2H5OH solution. | Lele Cao Lisheng Tang Qing Li Wenbo Liu | 2019 | Paper And Biomaterials2019，4，3： | 2 |
| 3 | Near-Infrared-Excitable Organic Ultralong Phosphorescence through Multiphoton Absorption显示文摘Organic ultralong room-temperature phosphorescence(OURTP)with a long-lived triplet excited state up to several seconds has triggered widespread research interests,but most OURTP materials are excited by only ultraviolet(UV)or blue light owing to their unique stabilized triplet-and solid-state emission feature.Here,we demonstrate that near-infrared-(NIR-)excitable OURTP molecules can be rationally designed by implanting intra/intermolecular charge transfer(CT)characteristics into Haggregation to stimulate the efficient nonlinear multiphoton absorption(MPA).The resultant upconverted MPA-OURTP show ultralong lifetimes over 0.42 s and a phosphorescence quantum yield of~37%under both UV and NIR light irradiation.Empowered by the extraordinary MPA-OURTP,novel applications including two-photon bioimaging,visual laser power detection and excitation,and lifetime multiplexing encryption devices were successfully realized.These discoveries illustrate not only a delicate design map for the construction of NIR-excitable OURTP materials but also insightful guidance for exploring OURTP-based nonlinear optoelectronic properties and applications. | Ye Tao Lele Tang Qi Wei Jibiao Jin Wenbo Hu Runfeng Chen Qingqing Yang Huanhuan Li Ping Li Guichuan Xing Quli Fan Chao Zheng Wei Huang | 2020 | Research2020，，1： | 1 |

| 6 | Electrocatalytic C0_(2) Reduction with Re-Based Spiro Bipyridine Complexes: Effects of the Local Proton in the Second Coordination Sphere显示文摘We report herein a Re-based tricarbonyl catalyst[fac-Re(L1)(CO)_(3)Cl](Re1)bearing a spiro center and a phenol group as a local proton source in the second coordination sphere.Due to the large steric spiro group,dimerization of one-electron reduced species was completely eliminated,improving the stability of Re1.Simultaneously,the phenol group in the second coordination sphere improves the formation of an H-bonding chain that promotes the protonation of C0_(2) reduction intermediates,boosting the electrocatalytic C0_(2) reduction activity of Re1.Mechanistic studies reveal that the doubly reduced complex Re1b is active for C0_(2) addition. | Yong Yang Ziyun Zhang Zhenyu Zhang Chao Tang Xiaoyong Chang Lele Duan | 2021 | Chinese Journal of Chemistry2021，39，5： | 1 |

| 9 | Simultaneous Photocatalytic Oxygen Production and Hexavalent Chromium Reduction in Ag_(3)PO_(4)/C_(3)N_(4)S-scheme Heterojunction显示文摘The low separation/migration efficiency is a major obstacle that limits the practical application of semiconductor-photocatalysts. Constructing S-scheme heterojunction is an ideal strategy for providing high photocatalytic activity via accelerating charge separation. Herein, an AgPO/CNcomposite was synthesized by coupling AgPOparticle with CNhollow spheres in-situ via a precipitation method. The S-scheme hete-rojunction between AgPOand CNcould accelerate the charge separation and retain high photoredox ability, which synchronously realized high photocatalytic oxygen production and hexavalent chromium reduction. The optimized Ag3PO4/CNcomposite shows a high oxygen production rate up to 803.31 μmol·g·hand a high conversion(87.9%) of Cr(Ⅵ) to Cr(Ⅲ). In addition, CNhollow spheres affords higher reaction efficiency than that of CNtube, CNbulk and CNsheet, which indicates that the hollow sphere structure can provide more active sites and adsorption sites in the photocatalytic process. This work offers an effective way in developing a dual-function S-scheme heterojunction for clean energy production and environmental protection. | Tao Yang Pengke Deng Lele Wang Jie Hu Qinqin Liu Hua Tang | 2022 | Chinese Journal of Structural Chemistry2022，41，6： | 1 |
| 10 | Plasmonic TiN nanobelts assisted broad spectrum photocatalytic H_(2) generation显示文摘The conversion of solar energy in a wide spectrum region to clean fuel,H_(2),remains a challenge in the field of photocatalysis.Herein,plasmonic TiN nanobelts,as a novel cocatalyst,were coupled with CdS nanoparticles to construct a 0D/1D CdS/TiN heterojunction.Utilization of the localized surface plasmon resonance(LSPR)effect generated from TiN nanobelts was effective in promoting light absorption in the near-infrared region,accelerating charge separation,and generating hot electrons,which can effectively improve the photocatalytic H_(2) generation activity of the 0D/1D CdS/TiN heterojunction over a wide spectral range.Furthermore,owing to the high metallicity and low work function,an ohmic-junction was formed between the CdS and TiN,favoring the transfer of hot electrons generated from TiN nanobelts the CdS nanoparticles,followed by the reaction with water to generate H_(2).Consequently,the 0D/1D CdS/TiN heterojunction demonstrated H_(2) generation activity even under light irradiation at 760 nm,while the pure CdS and Pt nanoparticles modified CdS presented no activity.This work opens a new insight into coupling plasmonic cocatalysts to realize full spectrum H_(2) production. | Xudong He Qinqin Liu Difa Xu Lele Wang Hua Tang | 2022 | Journal of Materials Science & Technology2022，，21： | 0 |
| 11 | Few-Atom Copper Catalyst for the Electrochemical Reduction of CO to Acetate:Synergetic Catalysis between Neighboring Cu Atoms显示文摘Single-atom catalysts(SACs)are gaining increasing recognition because of their superior catalytic properties for various reactions.However,the performance of SACs is often limited by the lack of neighboring metal centers to cooperate in catalysis.Herein,a synergetic interaction between neighboring Cu atoms of a few-atom catalyst(FAC)on graphdiyne(GDY)is found to greatly enhance the production of acetate in the CO electroreduction reaction relative to Cu SACs.In a 1.0 M KOH electrolyte,this Cu FAC exhibits an acetate Faradaic efficiency of 53.8±1.5%,an ultrahigh relative purity of up to 97 wt%for liquid products,and excellent stability over 23 h continuous electrolysis at–0.8 V versus reversible hydrogen electrode.Theoretical studies suggest that the intersite catalytic communication between two neighboring metal atoms confined in each pore of GDY facilitates the formation of acetic acid through either stepwise hydrogenation of CH_(2)CO^(*)or the direct reaction of H_(2)Owith CH_(2)CO^(*).Our study demonstrates the unprecedented synergetic catalysis of Cu FAC in promoting the selective CO electroreduction toward acetate production. | Weifeng Rong Haiyuan Zou Sha Tan Enyuan Hu Fan Li Chao Tang Hao Dai Shuting Wei Yongfei Ji Lele Duan | 2023 | CCS Chemistry2023，5，5： | 0 |
| 12 | Relative Varying Dynamics Based Whole Cutting Process Optimization for Thin‑walled Parts显示文摘Thin-walled parts are typically difficult-to-cut components due to the complex dynamics in cutting process.The dynamics is variant for part during machining,but invariant for machine tool.The variation of the relative dynamics results in the difference of cutting stage division and cutting parameter selection.This paper develops a novel method for whole cutting process optimization based on the relative varying dynamic characteristic of machining system.A new strategy to distinguish cutting stages depending on the dominated dynamics during machining process is proposed,and a thickness-dependent model to predict the dynamics of part is developed.Optimal cutting parameters change with stages,which can be divided by the critical thickness of part.Based on the dynamics comparison between machine tool and thickness-varying part,the critical thicknesses are predicted by an iterative algorithm.The proposed method is validated by the machining of three benchmarks.Good agreements have been obtained between prediction and experimental results in terms of stages identification,meanwhile,the optimized parameters perform well during the whole cutting process. | Yuyang Tang Jun Zhang Jia Yin Lele Bai Huijie Zhang Wanhua Zhao | 2022 | Chinese Journal of Mechanical Engineering2022，35，6： | 0 |
| 13 | Coordination-driven self-assembly of metallo-nanodrugs for local inflammation alleviation显示文摘Developing dedicated nanomedicines to improve delivery efficacy of anti-inflammatory drugs is still a formidable challenge.In this study,we present an extremely simple yet efficient approach to obtain hybrid nanodrugs through metal-drug coordination-driven self-assembly for carrier-free drug delivery.The resulting metallo-nanodrugs exhibit well-defined morphology and high drug encapsulation capability,allowing for the combination of magnetic resonance imaging and anti-inflammatory therapy.In the case of osteoarthritis(OA),the metallo-nanodrugs remarkably alleviate synovial inflammation,preventing cartilage destruction and extracellular matrix loss.In addition,it led to significantly improved therapeutic efficacy compared with intra-articular administration of the same dose of free drugs in OA mouse model.This work provides a very simple approach for the development of anti-inflammatory nanoformulations by exploiting coordination-driven self-assembly. | Lijuan Tang Zhenghan Di Jingfang Zhang Feiying Yin Lele Li Li Zheng | 2023 | Nano Research2023，16，12： | 0 |
