| 1 | Preparation of nitrogen doped clews-like carbon materials and their application as the electrode in supercapacitor显示文摘In this work, nitrogen doped clews-like carbon materials were successfully fabricated through hydrothermal polymerization method, followed by post treatment that integrated the carbonization,activation and post-nitrogen doping into one process. This preparation method can form particular hierarchical porous structure without using any sacrificial templates. The experimental results show that the nitrogen doped clews-like hierarchical porous carbon materials possess a relatively high specific surface area of 815 m^2/g with the nitrogen content of 10.58 at%. The electrochemical properties show that the resulting sample delivers 258 F/g at a 0.5 A/g and excellent capacity retention of 79% at 20 A/g. After conducting 10,000 charge-discharge cycles at 10 A/g, the capacitance retention of 98.3% is achieved.These intriguing results demonstrate that the obtained nitrogen doped clews-like carbon materials will be promising electrode materials for supercapacitor and other energy storage devices. | Shengrui Chen Jiyuan Liang Jinxing Zhao Haifeng Li Yan Liu Heming Deng Chang Liu Shun Tang Yuan-Cheng Cao | 2019 | Chinese Chemical Letters2019，30，3： | 2 |
| 2 | Construction of [Cu_nI_n]-based coordination polymers via flexible benzimidazolyl-based ligands显示文摘Four new [CunIn]-based coordination polymers, [{Cu4(μ3-I)4(mbbm)2}·2DMF]n (1), [(CuI)2(mbbm)2]n (2), [{Cu2(μ-I)2-(ebbm)2}·2MeCN]n (3), and [Cu2(μ-I)2(prbbm)2]n (4), were prepared from solvothermal reactions of CuI with three flexible ligands [(bzim)(CH2)n(bzim)] (bzim = benzimidazole; n = 1, mbbm; n = 2, ebbm; n = 3, prbbm). These compounds were characterized by elemental analysis, IR and X-ray crystallography. 1 consists of cubanelike [Cu4(μ3-I)4] fragments that link the neighboring ones via mbbm bridges to form a 1D ladder-type chain. 2 contains mononuclear [CuI] fragments that are bridged by mbbm ligands to yield a 1D zigzag chain. 3 or 4 contains a [Cu2(μ-I)2] dimeric fragment, which works as a four-connecting node to link its four equivalent ones to form a 2D (4,4) network (3) or acts as a two-connecting node to connect its two equivalent ones via two pairs of prbbm bridges to form a 1D double chain (4). The photoluminescent properties of 1-4 in the solid state at ambient temperature were investigated. | LI LingLing, REN ZhiGang, Lü Xue, WANG HeMing, CHANG YuJie, LI HongXi, WU Bing & LANG JianPing College of Chemistry, Chemical Engineering and Materials Science, Suzhou University, Suzhou 215123, China | 2010 | Science China Chemistry2010，53，10： | 1 |
| 3 | SEPARATION OF Re AND Mo BY ADSORPTION OF ACTIVE CARBON显示文摘Separation of Re and Mo by adsorption of active carbon has been studied. The results show that Re and Mo can be separated effectively by adjusting the pH value. As pH>8.2. the coefficient of separation SRc/Mo>3.042. The adsorption isotherm for Re conforms to the Freundlich formula. | Chen, Delin Chang, Heming Meng, Qingying Xing, Changce Liaoning Institute of Technology, Jinzhou 121001, China | 1993 | 中国有色金属学会会刊:英文版1993，3，1： | 0 |
| 4 | Research advances in peptide-drug conjugates显示文摘Peptide-drug conjugates(PDCs)are drug delivery systems consisting of a drug covalently coupled to a multifunctional peptide via a cleavable linker.As an emerging prodrug strategy,PDCs not only preserve the function and bioactivity of the peptides but also release the drugs responsively with the cleavable property of the linkers.Given the ability to significantly improve the circulation stability and targeting of drugs in vivo and reduce the toxic side effects of drugs,PDCs have already been extensively applied in drug delivery.Herein,we review the types and mechanisms of peptides,linkers and drugs used to construct PDCs,and summarize the clinical applications and challenges of PDC drugs. | Liming Gong Heming Zhao Yanhong Liu Hao Wu Chao Liu Shuangyan Chang Liqing Chen Mingji Jin Qiming Wang Zhonggao Gao Wei Huang | 2023 | Acta Pharmaceutica Sinica B2023，13，9： | 0 |
| 5 | Multi-scale analysis on the pulverized coal flow behaviors under high,pressure dense-phase pneumatic conveying显示文摘To deeply knowledge of the flow behaviors of pulverized coal particles in dense gas-solid two-phase flow,a multi-scale analysis method based on electrostatic sensor array is applied for the multi-scale characterization of flow behaviors of dense gas-solid flow.The experimental results indicate that:for steady flow,with the increment of conveying pressure difference,the individual particles increase and the particle clusters decrease,the individual particle distribution is always inhomogeneous but the particle cluster distribution tends to be more homogeneous over the cross-section of pipe,while the average flow behavior of pulverized coal particles is always in the relatively static state.For unsteady flow,the average flow behavior of pulverized coal particles is dynamic,and the flow behaviors of the multi-scale flow structures over the cross-section of pipe are all significantly inhomogeneous.Moreover,the effect of particle size on flow behavior of pulverized coal is also investigated and validated. | Heming Gao Xiaojuan Wang Qi Chang | 2022 | Particuology2022，20，1： | 0 |
| 6 | Kinetics of Nitrogen Removal from Molten Steel under Vacuum and Gas-Blowing Conditions显示文摘The kinetics of nitrogen removal from molten steel under vacuum and gas-blowing conditions has beenstudied during the VIM process. The experimental results indicated that vacuum affected the kinetics of nitrogenremoval in the range of 67-5 360 Pa. At 67 Pa, the rate of nitrogen removal is controlled by the liquid phase masstransfer of nitrogen in molten steel. At 2 680Pa, the limited step for nitrogen removal from molten steel is the chemical reaction at the metal/gas interface. Under the present experimental conditions, the type (Ar, CO, CO2) and quantity of gas flowed have no evident influences on the rate of nitrogen removal. The ratio of nitrogen removal of gasbubbles is less than 3 %. Based on the experimental results, the mechanism of nitrogen removal during the VDprocess with argon blowing and the other melting or secondary refining processes with carbon-oxygen reaction havebeen discussed. Some new viewpoints are proposed. | Jie Fu Heming Chang Shixiang Zhou Boping Chen (Metallurgy Engineering School, University of Science and Technology Beijing, Beijing 100083, China) | 1998 | International Journal of Minerals,Metallurgy and Materials1998，12，1： | 0 |
| 7 | THERMODYNAMIC PROPERTIES OF Fe-V-Ce LIQUID SOLUTION显示文摘Thermodynamic properties of the Fe-V-Ce liquid solutions have been studied in the tempera-ture range of 1550-1650℃.
