| 1 | Indirect mineral carbonation of titanium-bearing blast furnace slag coupled with recovery of TiO_2 and Al_2O_3显示文摘Large quantities of CO_2 and blast furnace slag are discharged in the iron and steel industry. Mineral carbonation of blast furnace slag can offer substantial CO_2 emission reduction and comprehensive utilization of the solid waste.This paper describes a novel route for indirect mineral carbonation of titanium-bearing blast furnace(TBBF) slag,in which the TBBF slag is roasted with recyclable(NH_4)_2SO_4(AS) at low temperatures and converted into the sulphates of various valuable metals, including calcium, magnesium, aluminium and titanium. High value added Ti-and Al-rich products can be obtained through stepwise precipitation of the leaching solution from the roasted slag. The NH_3 produced during the roasting is used to capture CO_2 from flue gases. The NH_4HCO_3 and(NH_4)_2CO_3 thus obtained are used to carbonate the CaSO_4-containing leaching residue and MgSO_4-rich leaching solution, respectively. In this study, the process parameters and efficiency for the roasting, carbonation and Ti and Al recovery were investigated in detail. The results showed that the sulfation ratios of calcium,magnesium, titanium and aluminium reached 92.6%, 87% and 84.4%, respectively, after roasting at an AS-to-TBBF slag mass ratio of 2:1 and 350 °C for 2 h. The leaching solution was subjected to hydrolysis at 102 °C for 4 h with a Ti hydrolysis ratio of 95.7% and the purity of TiO_2 in the calcined hydrolysate reached 98 wt%.99.7% of aluminium in the Ti-depleted leaching solution was precipitated by using NH_3. The carbonation products of Ca and Mg were CaCO_3 and(NH_4)_2 Mg(CO_3)_2·4H_2O, respectively. The latter can be decomposed into MgCO_3 at 100–200 °C with simultaneous recovery of the NH_3 for reuse. In this process, approximately 82.1% of Ca and 84.2%of Mg in the TBBF slag were transformed into stable carbonates and the total CO_2 sequestration capacity per ton of TBBF slag reached up to 239.7 kg. The TiO_2 obtained can be used directly as an end product, while the Al-rich precipitate and the two carbonation products can act, respectively, as raw materials for electrolytic aluminium,cement and light magnesium carbonate production for the replacement of natural resources. | Lin Wang Weizao Liu Jingpeng Hu Qiang Liu Hairong Yue Bin Liang Guoquan Zhang Dongmei Luo Heping Xie Chun Li | 2018 | Chinese Journal of Chemical Engineering2018，26，3： | 14 |
| 2 | Regenerative Role of Soil Seed Banks of Different Successional Stages in A Saline-alkaline Grassland in Northeast China显示文摘Soil seed banks can act as a potential seed source for natural revegetation and restoration. However, in a saline-alkaline grassland, it remains unclear how the stages of vegetation succession affect the characteristics of soil seed banks and the potential of soil seed banks of different successional stages for vegetation restoration. In this study, seasonal changes of the soil seed bank, and seed production and dispersal dynamics along degradation successional gradients were investigated in a saline-alkaline grassland in Northeast China, where the dominant grass during the 1960 s, Leymus chinensis was replaced with the secondary successional order of Puccinellia chinampoensis, Chloris virgata, and Suaeda salsa, together with bare patches. It was found that the soil seed bank composition varied according to the changing vegetation and had the highest species richness(7–16) in the climax successional stage, but had a low S?rensen similarity(0.22–0.37) with the aboveground vegetation. There was a high seed density of the soil seed bank(21 062–62 166/m2 in August and December) and also high S?rensen similarity index values(0.47–0.60) in the secondary successional stages of P. chinampoensis, C. virgata, and S. salsa. In bare patches, there were many seeds in the soil seed bank and some seedlings also appeared in the aboveground vegetation, indicating the existence of a persistent soil seed bank. Seed density and species richness differed substantially among the different successional stages, which was related to the reproductive characteristics of the standing plants in vegetation communities. Due to the lack of propagules of perennial species, especially the climax species of L. chinensis, in the soil, the successful restoration of the degraded saline-alkaline grassland was not possible. The study proved that in a degraded saline-alkaline grassland dominated by biennial or annual species, the soil seed bank was important for the revegetation of the current dominant plants, but not for the restoration of the original target species. Therefore, it is necessary to induce seeds or other propagules of the target perennial species. | MA Hongyuan LI Jingpeng YANG Fan Lü Xiaotao PAN Yuepeng LIANG Zhengwei | 2018 | Chinese Geographical Science2018，28，4： | 5 |
| 3 | In-situ/operando techniques to identify active sites for thermochemical conversion of CO_(2) over heterogeneous catalysts显示文摘The catalytic conversion of CO_(2) to fuels or chemicals is considered to be an effective pathway to mitigate the greenhouse effect. To develop new types of efficient and durable catalysts, it is critical to identify the catalytic active sites, surface intermediates, and reaction mechanisms to reveal the relationship between the active sites and catalytic performance. However, the structure of a heterogeneous catalyst usually dynamically changes during reaction, bringing a great challenge for the identification of catalytic active sites and reaction pathways. Therefore, in-situ/operando techniques have been employed to real-time monitor the dynamic evolution of the structure of active sites under actual reaction conditions to precisely build the structure–function relationship. Here, we review the recent progress in the application of various in-situ/operando techniques in identifying active sites for catalytic conversion of CO_(2) over heterogeneous catalysts. We systematically summarize the applications of various optical and X-ray spectroscopy techniques, including Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and X-ray absorption spectroscopy (XAS), in identifying active sites and determining reaction mechanisms of the CO_(2) thermochemical conversion with hydrogen and light alkanes over heterogeneous catalysts. Finally, we discuss challenges and opportunities for the development of in-situ characterization in the future to further enlarge the capability of these powerful techniques. | Kai Feng Yaning Wang Man Guo Jingpeng Zhang Zhengwen Li Tianyu Deng Zhihe Zhang Binhang Yan | 2021 | Journal of Energy Chemistry2021，30，11： | 5 |
| 4 | Preparation of poly(glutamic acid) shielding micelles self-assembled from polylysine-b-polyphenylalanine for gene and drug codelivery显示文摘A novel amphiphilic cationic block copolymer polylysine-b-polyphenylalanine(PLL-b-PPhe)was synthesized and self-assembled into micelles in aqueous solution,then shielded with poly(glutamic acid)(marked as PG/PLL-b-PPhe)to codeliver gene and drug for combination cancer therapy.Here,doxorubicin(DOX)was selected to be loaded into PLL-b-PPhe micelles and the drug loading efficiency was 8.0%.The drug release studies revealed that the PLL-b-PPhe micelles were pH sensitive and the released DOX could reach to 53.0%,65.0%,72.0%at pH 7.4,6.8 and 5.0,respectively.In order to reduce positive charge and cytotoxicity of PLL-b-PPhe micelles,PG was used as shelding,simultaneously condensed with Bcl2 siRNA to form gene carrier system.Compared with PEI,PG/PLL-b-PPhe had excellent gene transfection efficiency,especially when the molar ratio of PLL to PPhe was 30:60 and the mixed mass ratio of PLL-b-PPhe to gene was 5:1.More importantly,DOX and Bcl2 siRNA gene codelivery system displayed remarkable cytotoxicity against B16 F10 cells.Confocal laser scanning microscopy(CLSM)and flow cytometry were used to characterize endocytosis of the codelivery system,and confirmed that both DOX and Bcl2 siRNA had been endocytosed into B16 F10 cells.The above results indicated that gene and drug codelivery was a promising strategy in future cancer therapy. | Jing Ma Jingpeng Zhang Lin Chi Chong Liu Yanhui Li Huayu Tian | 2020 | Chinese Chemical Letters2020，31，6： | 4 |
| 5 | Evaluation of Surface Relative Humidity in China from the CRA-40 and Current Reanalyses显示文摘Recently,the China Meteorological Administration(CMA)released a new Global Atmospheric Reanalysis(CRA-40)dataset for the period 1979−2018.In this study,surface relative humidity(RH)from CRA-40 and other current reanalyses(e.g.,CFSR,ERA5,ERA-Interim,JRA-55,and MERRA-2)is comprehensively evaluated against homogenized observations over China.The results suggest that most reanalyses overestimate the observations by 15%−30%(absolute difference)over the Tibetan Plateau but underestimate the observations by 5%−10%over most of northern China.The CRA-40 performs relatively well in describing the long-term change and variance seen in the observed surface RH over China.Most of the reanalyses reproduce the observed surface RH climatology and interannual variations well,while few reanalyses can capture the observed long-term RH trends over China.Among these reanalyses,the CFSR does poorly in describing the interannual changes in the observed RH,especially in Southwest China.An empirical orthogonal function(EOF)analysis also suggests that the CRA-40 performs better than other reanalyses to capture the first two leading EOF modes revealed by the observations.The results of this study are expected to improve understanding of the strengths and weaknesses of the current reanalysis products and thus facilitate their application. | Jingpeng ZHANG Tianbao ZHAO Zhi LI Chunxiang LI Zhen LI Kairan YING Chunxiang SHI Lipeng JIANG Wenyu ZHANG | 2021 | Advances in Atmospheric Sciences2021，38，11： | 4 |
| 6 | Cellulose nanofiber separator for suppressing shuttle effect and Li dendrite formation in lithium-sulfur batteries显示文摘Lithium-sulfur battery(LSB) has high energy density but is limited by the polysulfides shuttle and dendrite growth during cycling. Herein, a free-standing cellulose nanofiber(CNF) separator is designed and fabricated in isopropanol/water suspension through vacuum filtration progress. CNFs with abundant polar oxygen-containing functional groups can chemically immobilize the polysulfides, and suppress the formation of the dendrites by controlling the surface morphology of the SEI on lithium metal in LSB. The isopropanol content in a suspension can fine-tune the pore structure of the membrane to achieve optimal electrochemical performance. The prepared separator displays integrated advantages of an ultrathin thickness(19 μm), lightweight(0.87 mg cm^(-2)), extremely high porosity(98.05%), and decent electrolyte affinity. As a result, the discharge capacity of the LSB with CNF separator at the first and 100 th cycle is 1.4 and 1.3 times that of PP separator, respectively. Our research provides an environmentalfriendly and facile strategy for the preparation of multifunctional separators for LSBs. | Jingxue Li Liqin Dai Zhefan Wang Hao Wang Lijing Xie Jingpeng Chen Chong Yan Hong Yuan Hongliang Wang Chengmeng Chen | 2022 | Journal of Energy Chemistry2022，31，4： | 4 |
| 7 | Direct aerobic oxidation of monoalcohol and diols to acetals using tandem Ru@MOF catalysts显示文摘The aerobic oxidation of monoalcohols and diols to acetals is an important academic and industrial challenge for the production of fine chemicals and intermediates.The existing methods usually rely on a two-step process in which alcohols are first oxidized to aldehydes over metal catalysts(Ru,Pt,Pd)and then acetalized using acids.Due to the instability of aldehydes,how to avoid over-oxidation to their respective carboxylic acids and esters is a long-standing challenge.For this reason,certain non-conjugated dialdehydes have never been successfully produced from diol oxidation.Hereby we report a Ru@metal-organic framework(MOF)tandem catalyst containing ultra-fine Ru nanoparticles(<2 nm)for direct alcohol to acetal conversion of monoalcohol and diols with noformation of carboxylic acids.Mechanistic study reveals that the presence of Lewis acid sites in the MOF work in concert with Ru active sites to promptly convert aldehydes to acetals thereby effectively suppressing the formation of over-oxidation byproducts. | Songwei Zhang Jerry Pui Ho Li Jingpeng Zhao Dan Wu Biao Yuan Willinton Yesid Hernandez Wen-Juan Zhou Tao He Yi Yu Yong Yang Vitaly Ordomsky Tao Li | 2021 | Nano Research2021，14，2： | 2 |
| 8 | Spatiotemporal distribution and decadal change of the monthly temperature predictability limit in China显示文摘Based on the nonlinear Lyapunov exponent and nonlinear error growth dynamics, the spatiotemporal distribution and decadal change of the monthly temperature predictability limit(MTPL) in China is quantitatively analyzed. Data used are daily temperature of 518 stations from 1960 to 2011 in China. The results are summarized as follows:(1) The spatial distribution of MTPL varies regionally. MTPL is higher in most areas of Northeast China, southwest Yunnan Province, and the eastern part of Northwest China. MTPL is lower in the middle and lower reaches of the Yangtze River and Huang-huai Basin.(2)The spatial distribution of MTPL varies distinctly with seasons. MTPL is higher in boreal summer than in boreal winter.(3) MTPL has had distinct decadal changes in China, with increase since the 1970 s and decrease since2000. Especially in the northeast part of the country, MTPL has significantly increased since 1986. Decadal change of MTPL in Northwest China, Northeast China and the Huang-huai Basin may have a close relationship with the persistence of temperature anomaly. Since the beginning of the 21 st century, MTPL has decreased slowly in most of the country, except for the south. The research provides a scientific foundation to understand the mechanism of monthly temperature anomalies and an important reference for improvement of monthly temperature prediction. | Weijing Li Jingpeng Liu Lijuan Chen Peiqun Zhang Hongli Ren | 2014 | Chinese Science Bulletin2014，59，34： | 2 |
| 9 | An improved estimation of distribution algorithm for multi-compartment electric vehicle routing problem显示文摘The multi-compartment electric vehicle routing problem(EVRP)with soft time window and multiple charging types(MCEVRP-STW&MCT)is studied,in which electric multi-compartment vehicles that are environmentally friendly but need to be recharged in course of transport process,are employed.A mathematical model for this optimization problem is established with the objective of minimizing the function composed of vehicle cost,distribution cost,time window penalty cost and charging service cost.To solve the problem,an estimation of the distribution algorithm based on Lévy flight(EDA-LF)is proposed to perform a local search at each iteration to prevent the algorithm from falling into local optimum.Experimental results demonstrate that the EDA-LF algorithm can find better solutions and has stronger robustness than the basic EDA algorithm.In addition,when comparing with existing algorithms,the result shows that the EDA-LF can often get better solutions in a relatively short time when solving medium and large-scale instances.Further experiments show that using electric multi-compartment vehicles to deliver incompatible products can produce better results than using traditional fuel vehicles. | SHEN Yindong PENG Liwen LI Jingpeng | 2021 | Journal of Systems Engineering and Electronics2021，32，2： | 2 |

| 11 | Robust Electric Vehicle Routing Problem with Time Windows under Demand Uncertainty and Weight-Related Energy Consumption显示文摘Vehicle routing problem with time windows(VRPTW)is a core combinatorial optimization problem in distribution tasks.The electric vehicle routing problem with time windows under demand uncertainty and weight-related energy consumption is an extension of the VRPTW.Although some researchers have studied either the electric VRPTW with nonlinear energy consumption model or the impact of the uncertain customer demand on the conventional vehicles,the literature on the integration of uncertain demand and energy consumption of electric vehicles is still scarce.However,practically,it is usually not feasible to ignore the uncertainty of customer demand and the weight-related energy consumption of electronic vehicles(EVs)in actual operation.Hence,we propose the robust optimization model based on a route-related uncertain set to tackle this problem.Moreover,adaptive large neighbourhood search heuristic has been developed to solve the problem due to the NP-hard nature of the problem.The effectiveness of the method is verified by experiments,and the influence of uncertain demand and uncertain parameters on the solution is further explored. | Yindong Shen Leqin Yu Jingpeng Li | 2022 | Complex System Modeling and Simulation2022，2，1： | 1 |

| 16 | CDK1、CDK2 siRNA干扰对肿瘤细胞凋亡和细胞周期的影响(英文)显示文摘Objective:We investigated the influence of CDK1 and CDK2 expression inhibited by cotransfection of CDK1 and CDK2 siRNA on cell cycle and apoptosis,explored the exact role of cell cycle master regulator in tumor cell apoptosis process.Methods:The siRNA targeting the CDK1 and CDK2 genes were synthesized and simultaneously cotransfected into Hela cells by lipofectamine 2000.48 or 60 h after the cotransfection,CDK1 and CDK2 protein expressions were examined by Western blot.Cell cycle distribution was analyzed by flow cytometry.Cell apoptosis was detected by the Annexin V/PI method.The changes of the transfected cell morphological under a microscope after Wright-Giemsa Staining were studied.Results:CDK1 and CDK2 protein expression was decreased at 48 or 60 h after cotransfection.The accumulation of the G2/M and S phase population in cell cycle of the cotransfected cells at 48 or 60 h after transfection was enhanced obviously compared with control.The ratio of apoptotic cell of cotransfected cells at 48 or 60 h after transfection was increased significantly compared with control.More binucleate or multinucleate cells among cotransfected cells were observed under the microscope.Conclusion:The decreased expression of CDK1 and CDK2 by cotransfection of CDK1 and CDK2 siRNA not only leads to tumor cell cycle arrest in S phase and G2/M phase,but also induces tumor cell apoptosis. | Hui Xiao Wanjun Gong Jingpeng Cao Xiaolan Li Deding Tao Junbo Hu Jianping Gong | 2009 | The Chinese-German Journal of Clinical Oncology2009，8，7： | 1 |
| 17 | Review of Carbon Dots from Lignin: Preparing, Tuning, and Applying显示文摘Carbon dots(CDs),emerging carbon materials with unique physical and chemical properties,have drawn extensive attention from researchers.In recent years,many carbon sources have been used as precursors for preparing CDs.In contrast to other types of precursors,lignin,as a renewable and available source of natural aromatic biopolymers,is believed to be a low-cost precursor for the large-scale preparation of CDs.However,the preparation of CDs with excellent optical properties from lignin has some drawbacks because of the complex structure of lignin.Hence,the methods for preparing the CDs from lignin are summarized in this paper,and the mechanism and physical and chemical properties of lignin-based CDs are discussed.Moreover,some approaches to tuning the optical properties of lignin-based CDs have been proposed.Additionally,the use of lignin-based CDs in the fields of sensing,supercapacitor,bioimaging,anti-counterfeiting,and information encryption is reviewed. | Tao Zhang Haiming Li Jingpeng Zhou Xing Wang Lingping Xiao Fengshan Zhang Yanzhu Guo | 2022 | Paper And Biomaterials2022，7，3： | 1 |
